Title: Light bulb shaped lamp and lighting apparatus

Description:
TECHNICAL FIELD 
     The present invention relates to a light bulb shaped lamp having a semiconductor light-emitting device and a lighting apparatus which includes the light bulb shaped lamp. 
     BACKGROUND ART 
     Compared to conventional illumination light source, light-emitting diodes (LED) which are semiconductor light-emitting devices are small, have high efficiency and long product life. Recent market needs for saving energy and resource boosts the demand for light bulb shaped lamps using LEDs (hereafter simply referred to as “LED light bulb”) and lighting apparatuses including the LED light bulbs, replacing conventional incandescent light bulbs using filament coils. 
     Known properties of LEDs include reduced light output as temperature increases, which lead to shorter product life. In response to this problem, a metal case is provided between a semispherical globe and a base in a conventional LED light bulb so as to suppress the increase in the temperature of LED (for example, see Patent Literature 1). The metal case functions as a heat sink for radiating heat generated in LED to outside, making it possible to suppress the increase in the temperature of LED and prevent reduction in the light output.

     SUMMARY OF INVENTION 
     Technical Problem 
     However, in the conventional LED light bulb described above, LEDs are provided on the surface of the metal case in the globe. More specifically, the conventional LED light bulb has a configuration in which all of the light emitted by the LED travelling toward the base is blocked. Accordingly, there is a problem with the conventional LED light bulb that the most of the light emitted by the LED (semiconductor light-emitting device) is blocked by the case. 
     The present invention has been conceived to solve the problem described above, and it is an object of the present invention to provide a light bulb shaped lamp and others which suppresses the possibility of most of the light emitted by the semiconductor light-emitting device being blocked. 
     Solution to Problem 
     In order to solve the problem described above, the lightbulb-shaped lamp according to an aspect of the present invention includes a light-emitting module including: a base mount; and a semiconductor light-emitting device mounted on the base mount; and a lead wire for supplying power to the light-emitting module, in which the base mount is supported by the lead wire. 
     Accordingly, it is possible to suppress that a large amount of light emitted by the semiconductor light-emitting device is blocked. 
     It is preferable that the lead wire includes an elastic part which is elastic. 
     Stated differently, the lightbulb-shaped lamp includes a base mount and a light-emitting module having a semiconductor light-emitting device mounted on the base mount, and the lead wire for supplying power to the light-emitting module. The base mount on which the semiconductor light-emitting device is mounted is supported by the lead wire having an elastic part which is elastic. 
     Accordingly, even when the lightbulb-shaped lamp is shaken at the time of transportation by a truck, the elastic part suppresses (reduces) the vibration transmitted to the base mount. Accordingly, even when the lightbulb-shaped lamp is shaken, it is possible to reduce the possibility of malfunction caused by the vibration. 
     Here, for example, a lightbulb-shaped lamp (hereafter referred to as a solder-connected lamp) having a structure in which the end portion of the lead wire and the base mount are connected by solder is listed as an example. Furthermore, the lead wire of the solder-connected lamp does not have an elastic part.

     DESCRIPTION OF EMBODIMENTS 
     The following shall describe embodiments of the present invention with reference to the drawings. In the following description, the same reference numerals are assigned to the same components. The names and the functions of the components are the same as well. Accordingly, detailed description for these components may be omitted. 
     Note that the size, material, shape and relative arrangement of the components illustrated in the embodiments are appropriately changed depending on the configuration of the device to which the present invention is applied and various conditions. Accordingly, the present invention is not limited by the example. Furthermore, the size of the components in the drawings may be different from the actual size. 
     Embodiment 1 
     (Overall Structure of Light Bulb Shaped Lamp) 
     The overall structure of the light bulb shaped lamp  100  according to the embodiment 1 shall be described with reference to  FIG. 1  to  FIG. 3 . 
       FIG. 1  is a perspective view of the light bulb shaped lamp according to the embodiment 1. In  FIG. 1  to  FIG. 3 , the X, Y, and Z-axis directions are orthogonal to each other. The X, Y, and Z-axis directions in the drawings below are orthogonal to each other. 
       FIG. 2  is an exploded perspective view of the light bulb shaped lamp according to the embodiment 1. 
       FIG. 3  is a front view of the light bulb shaped lamp according to the embodiment 1. Note that, in  FIG. 3 , a lighting circuit  180  and part of lead wires  170   a  and  170   b  for power supply and for support which are positioned inside a base  190  are illustrated in dotted lines. 
     The light bulb shaped lamp  100  is a light bulb including a translucent globe  110  and a base  190  attached to the globe  110 . An LED module  200  in which a semiconductor light-emitting device is mounted is housed in the globe  110 . 
     More specifically, as illustrated in  FIG. 1  to  FIG. 3 , the light bulb shaped lamp  100  includes the LED module  200 , the lead wires  170   a  and  170   b , the globe  110 , a fixing part  120 , the base  190 , and the lighting circuit  180 . 
     The LED module  200  is a light-emitting module which emits illuminating light of a predetermined color. The detailed configuration of the LED module  200  shall be described later. Note that, the LED modules  200 A,  201 A,  202 A,  200 N,  200 B,  200 C,  200 D, and  200 E are the light-emitting modules similar to the LED module  200 . 
     The lead wires  170   a  and  170   b  are electric wires for supplying power to the semiconductor light-emitting device to be described later, and for holding (fixing) the LED module in a specific position in the globe  110 . The LED module  200  is electrically connected to the lead wires  170   a  and  170   b.    
     The lead wire  170   a  is a composite wire including an internal lead wire  171   a , a Dumet wire  172   a , and an external lead wire  173   a  joined in order. The lead wire  170   b  is a composite wire including an internal lead wire  171   b , a Dumet wire  172   b , and an external lead wire  173   b  joined in order. 
     In the following description, each of the lead wires  170   a  and  170   b  may be simply referred to as a lead wire  170 . Furthermore, in the following description, each of the internal lead wires  171   a  and  171   b  may be simply referred to as an internal lead wire  171 . Furthermore, in the following description, each of the Dumet wires  172   a  and  172   b  may be simply referred to as a Dumet wire  172 . Furthermore, in the following description, each of the external lead wires  173   a  and  173   b  may be simply referred to as an external lead wire  173 . 
     The internal lead wire  171  is an electric wire extending from the fixing part  120  to be described later to the LED module  200 . The internal lead wire  171  is joined with the base mount  210  to be described later, and supports the LED module  200  (the base mount  210 ). Stated differently, the base mount  210  to be described later is supported by the lead wires  170   a  and  170   b.    
     The Dumet wire  172  is sealed in the fixing part  120 . The external lead wire  173  is an electric wire extending from the lighting circuit  180  to the fixing part  120 . The internal lead wire  171  and the external lead wire  173  are, for example, metal wires containing copper. 
     Here, it is preferable that the lead wire  170  is a metal wire including copper having high thermal conductivity. With this, the heat generated at the LED module  200  can be actively transferred to the base  190  through the lead wire  170 . The lead wire  170  also has strength sufficient for supporting the LED module  200 . 
     Note that, the lead wire  170  is not limited to a composite wire, but may be a single wire composed of the same metal wire. In addition, two lead wires  170  do not have to be provided. For example, when the light bulb shaped lamp  100  includes a plurality of the LED modules  200  in the globe  110 , two lead wires  170  may be provided for each of the LED modules  200 . Accordingly, the light bulb shaped lamp  100  may include the lead wires  170  twice in number as the number of the LED modules  200 . 
     The fixing part  120  is a stem made of a material transparent to visible light. The transparent material is, for example, soft glass. 
     With this, the light bulb shaped lamp  100  can reduce the loss of light emitted by the semiconductor light-emitting device  330  to be described later caused by the fixing part  120 . The light bulb shaped lamp  100  can also prevent a shadow cast by the fixing part  120 . Since the fixing part  120  shines through the light emitted by the semiconductor light-emitting device  300 , the light bulb shaped lamp  100  also achieves visually superior appearance. 
     Note that, it is not necessary for the fixing part  120  to be transparent to the visible light, or to be made of soft glass. For example, the fixing part  120  may be a component made of a highly heat-conductive resin. As the highly heat-conductive resin, silicone resin in which metal particles such as alumina or zinc oxide are mixed may be used. 
     In this case, the light bulb shaped lamp  100  can actively transfer the heat generated at the LED module  200  to the base  190  through the fixing part  120 . As a result, the light bulb shaped lamp  100  is capable of suppressing reduction in light-emission efficacy and reduction in product life of the semiconductor light-emitting device  300  due to increased temperature. 
     Among the internal lead wire  171 , the Dumet wire  172 , and the external lead wire  173  composing the lead wire  170 , the fixing part  120  seals the Dumet wire  172 . To put it differently, the fixing part  120  fixes the lead wire  170  exposing a part of the lead wire  170  (the internal lead wire  171 ). 
     The fixing part  120  is provided extending from the opening  110  of the globe  110  toward the inside of the globe  110 . More specifically, the fixing part  120  is joined to an edge  111  of the opening of the globe  110  such that the longer direction of the fixing part  120  coincides with the Z-axis direction. In other words, the fixing part  120  according to the embodiment 1 is a component that would be obtained by extending the stem used for a common incandescent light bulb toward the inside of the globe  110   
     The fixing part  120  includes a rod part  120   a  having a rod shape. 
     Note that, the material composing the fixing part  120  is not limited to glass, but may be resin such as acrylic, metal, ceramic, or others. 
     The globe  110  covers the LED module  200 , part of the lead wires  170   a  and  170   b , a part of the fixing part  120 , and others. The LED module  200  is positioned at a part around the center of the globe  110 . The globe  110  is made of a translucent material. The translucent material is, for example, silica glass transparent to the visible light. 
     Accordingly, the user can see the LED module  200  housed in the globe  110  from outside of the globe  110 . With this, the light bulb shaped lamp  100  can reduce the loss of light emitted by the semiconductor light-emitting device  300  to be described later caused by the globe  110 . Furthermore, the light bulb shaped lamp  100  can achieve high heat resistance. 
     The light from the LED module  200  passes through the globe  110 , and is emitted to outside. 
     Since the LED module  200  is positioned around the center of the globe  110 , omnidirectional light distribution property is achieved when the LED module  200  emits light. 
     Note that, the material composing the globe  110  is not limited to glass, but may be resin such as acrylic. 
     The globe  110  has a shape with one end closed in a spherical shape, and the other end has an opening. In other words, the shape of the globe  110  is that a part of hollow sphere is narrowed down while extending away from the center of the sphere. The shape of the globe  110  is Type A (JIS C7710) which is the same as a common incandescent light bulb. 
     Note that, the shape of the globe  110  is not limited to Type A, but may also be Type G, Type E, or others. The globe  110  does not have to be transparent to visible light either, or made of silica glass. For example, the globe  110  may be a component made of resin such as acrylic. 
     The lower portion of the fixing part  120  is formed in a flared shape coinciding with the shape of the edge  111  at the opening. The lower portion of the fixing part  120  formed in the flared shape is joined to the edge  111  at the opening of the globe  110  so as to close the opening of the globe  110 . 
     With this structure, the inside of the globe  110  is kept airtight, and it is possible to prevent water or vapor from entering the inside of the globe  110 . Therefore, it is possible to suppress degradation in the LED module  200  and degradation in the part connected with the lead wire  170  caused by moisture. 
     Part of the two lead wires  170  are sealed in the fixing part  120 . Accordingly, it is possible to supply power to the LED module  200  in the globe  110  from outside of the globe  110  while keeping the globe  110  airtight. 
     Note that, the fixing part  120  does not necessarily close the opening at the globe  110 , and may be attached to the edge  111  of the opening  111 . 
     The base  190  is attached to the globe  110  using an adhesive such as cement to cover the opening of the globe  110 . The base  190  is a power receiving part for receiving the AC power. A conductive screw part  191  is formed on an outer side surface of the base  190 . An eyelet  192  is formed at the bottom part of the base  190 . 
     The base  190  is an E26 base, for example. The base  190  is attached to a socket for E26 base which is not illustrated. The AC power is supplied to the socket for E26 base from a commercial AC power supply which is not illustrated. More specifically, the screw part  191  and the eyelet  192  in the base  190  are supplied with the AC power from the socket for E26 base which is not illustrated. 
     Note that, the base  190  is not limited to an E26 base. The base  190  is, for example, an E17 base. Furthermore, the base  190  is not necessarily a screw-in base, but may be a plug-in base, for example. 
     The lighting circuit  180  is housed inside the base  190 . The lighting circuit  180  is electrically connected to the screw part  191  and the eyelet  192 . The lighting circuit  180  receives the AC power from the screw part  191  and the eyelet  192 . The lighting circuit  180  is electrically connected to the lead wires  170   a  and  170   b.    
     Although the details shall be described later, the lighting circuit  180  is a circuit for converting the AC power to the DC power. 
     Note that, the power supplied to the base  190  is not limited to the AC power from a commercial AC power source. The power supplied to the base  190  may be the DC power supplied from a battery, for example. In this case, the lighting circuit  180  is not necessary. 
     Note that, the base  190  has a structure which allows the base  190  to be directly attached to the opening of the globe  110 . However, the structure is not limited to this example. The base  190  may be attached to the globe  110  indirectly. For example, the base  190  may be attached to the globe  110  through a resin part such as a resin case. The resin case may store the lighting circuit and others, for example. 
     (The Configuration of LED Module) 
       FIG. 4  is a cross-sectional view illustrating the configuration of the LED module  200 . Note that, the lead wires  170   a  and  170   b  not included in the LED module  200  are also illustrated in  FIG. 4 . 
     Note that, the details on the shape of the lead wires  170   a  and  170   b  shall be described later. 
     The LED module  200  is housed in the globe  110 , and is preferably positioned at the center of the sphere defined by the globe  110 . The center is the center inside of the globe  110  at a part having a large inner-diameter. Since the LED module  200  is provided at the center, the light bulb shaped lamp  100  can achieve omnidirectional light distribution property when the light bulb shaped lamp  100  is switched on. The omnidirectional light distribution property is approximated to a common incandescent light bulb using conventional filament coil. 
     As shown in  FIG. 4 , the LED module  200  includes a base mount  210  and a plurality of semiconductor light-emitting devices  300 , and a sealing part  220 . 
     The base mount  210  is a component having translucent property with respect to visible light. The component is made of ceramic containing alumina, for example. 
     Note that, the translucent material is not limited to ceramic, and may be resin, glass, or others. 
     It is preferable that the base mount  210  is a component having high transmittance of visible light. With this, the light emitted from the semiconductor light-emitting device  300  passes through the inside of the base mount  210 , and the light is emitted from a part on which no semiconductor light-emitting device  300  is mounted. 
     Accordingly, even when the semiconductor light-emitting device  300  is mounted only on one side of the base mount, the light is emitted from the other surfaces, allowing to achieve the light distribution property equivalent to that of an incandescent light bulb. 
     Note that, only a part of the base mount  210  may be translucent with respect to visible light, instead of the entire base mount  210 . 
     Note that, the base mount  210  does not have to be translucent. In this case, the semiconductor light-emitting device  300  may be mounted on more than one side of the base mount  210 , for example. 
     The shape of the base mount  210  is a quadrangular prism, as illustrated in (a) in  FIG. 5 . Here, the length of the base mount  210  in the X-axis direction is 20 mm, for example. The length (width) of the base mount  210  in the Y-axis direction is 1 mm, for example. The thickness of the base mount  210  in the Z-axis direction is 0.8 mm, for example. 
     Note that, the shape of the base mount  210  is not limited to the quadrangular prism, and may be other shape. The shape of the base mount  210  may be like a board, as illustrated in  FIG. 5  ( b ). Here, the length of the base mount  210  in the X-axis direction is 20 mm, for example. The length (width) of the base mount  210  in the Y-axis direction is 10 mm, for example. The thickness of the base mount  210  in the Z-axis direction is 0.8 mm, for example. 
     If the shape of the base mount  210  is a quadrangular prism, the LED module  200  in the light bulb shaped lamp  100  can imitate the filament of an incandescent light bulb. 
     Note that, the shape and size of the base mount  210  are merely example, and may be in other shapes and sizes. The shape of the base mount  210  may be a hexagonal prism or an octagonal prism, for example. 
     Conductive power supply terminal  241   a  or  241   b  is provided on each of the ends of the base mount  210  in the longer direction (X-axis direction). 
     End portions of the lead wires  170   a  and  170   b  are fixed to the power supply terminals  241   a  and  241   b  by solder, respectively. Accordingly, the lead wires  170   a  and  170   b  are electrically connected to the power supply terminals  241   a  and  241   b , respectively. Stated differently, the lead wires  170   a  and  170   b  are fixed to the base mount  210  (LED module  200 ). 
     The base mount  210  has a main surface  211 . The semiconductor light-emitting devices  300  are mounted in a straight line on the main surface  211 . Stated differently, the semiconductor light-emitting devices  300  are mounted on the main surface  211  of the base mount  210  such that the semiconductor light-emitting devices  300  are arranged in a straight line between the power supply terminal  241   a  and the power supply terminal  241   b.    
     In the following description, the main surface of the quadrilateral or board-shaped base mount may also be referred to as the first surface. In addition, the surface of the base mount opposite to the first surface is referred to as the second surface. The first surface is the main surface  211 , for example. The second surface is the surface opposite to the main surface  211  of the base mount  210 . Accordingly, the base mount  210  has the first surface and the second surface. 
     A group of light-emitting devices  300   a  is composed of the semiconductor light-emitting devices  300  mounted on the main surface  211  on the base mount  210  in a straight line. The semiconductor light-emitting devices  300  composing the group of the light-emitting devices  300   a  are connected in series electrically. 
     The power is supplied to the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  from the lead wires  170   a  and  170   b . To put it differently, the lead wires  170   a  and  170   b  are electric wires for supplying power to the semiconductor light-emitting devices  300 . More specifically, the lead wires  170   a  and  170   b  are electric wires for supplying power to the LED module  200  as the light-emitting module. 
     Note that, if the shape of the base mount  210  is a quadrangular prism, the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  may be formed on a side surface of the base mount  210  different from the main surface  211 . 
     The base mount  210  has holes  250   a  and  250   b . Each of the holes  250   a  and  250   b  is a through hole passing through the base mount  210  from the main surface  211  (the first surface) of the base mount  210  toward the second surface opposite to the main surface  211 . 
     In the following description, each of the holes  250   a  and  250   b  may be simply referred to as the hole  250  as well. Each of the holes  250  extends diagonal to the Z-axis direction. 
     Note that, structure of the hole  250  is not limited to the structure in which the hole  250  extends diagonal to the Z-axis direction, and may extend along the Z-axis direction. 
     Note that, the fixing part  120  is provided on a side closer to a side of the base mount  210  (the second surface) opposite to the main surface  211  (the first surface). 
     In the following description, the semiconductor light-emitting device  300  on the left end of the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  in  FIG. 4  is also referred to as a left-end semiconductor light-emitting device. In addition, the semiconductor light-emitting device  300  at the right end of the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  is also referred to as a right-end semiconductor light-emitting device. 
     The semiconductor light-emitting device  300  is an LED chip which emits blue light, and shall be described in detail later. 
     The semiconductor light-emitting devices  300  mounted on the main surface  211  are connected in series electrically by the wire  301 . The wire  301  is, for example, a gold wire. 
     The left-end semiconductor light-emitting device is electrically connected to the power supply terminal  241   a  (lead wire  170   a ) through the wire  301 . The right-end semiconductor light-emitting device is electrically connected to the power supply terminal  241   b  (lead wire  170   b ) through the wire  301 . 
     The number of the semiconductor light-emitting device  300  composing the group of light-emitting devices  300   a  is, for example, 12. Note that the number of semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  is not limited to 12, and may be changed appropriately according to the purpose of the LED module. 
     The semiconductor light-emitting devices  300  arranged in a straight line and the wires  301  connected to the semiconductor light-emitting devices  300  are sealed by the sealing part  220 . The sealing part  220  seals the group of light-emitting devices  300   a . The sealing part  220  extends in the X-axis direction. Accordingly, the shape of the sealing part  220  is the straight-line shape. Stated differently, the shape of the sealing part  220  is an elongated shape. 
     Note that, if the semiconductor light-emitting device  300  is firmly fixed to the base mount  210 , the semiconductor light-emitting device  300  may not be sealed by the sealing part  220 . 
     The sealing part  220  is, for example, a translucent resin such as silicone resin. In the sealing part  220 , phosphor particles (not illustrated) which is a wavelength conversion material and light diffusion material (not illustrated) are dispersed. The phosphor is a YAG (yttrium, aluminum, and garnet) phosphor ((Y,Gd) 3 Al 5 O 12 :Ce 3+ , Y 3 Al 5 O 12 :Ce 3+ ), for example. The light diffusion material is silica, for example. 
     The cross-section in X-axis direction of the sealing material  220  formed as described above is dome-shaped, for example. The width of the cross-section is 1 mm, and the height of the cross-section is 0.2 mm, for example. 
     Note that, as illustrated in (b) in  FIG. 5 , if the base mount  210  is board-shaped, three sealing parts  220  for sealing the group of light-emitting devices  300   a  are formed on the main surface  211 , for example. Accordingly, three groups of light-emitting devices  300   a  are formed on the main surface  211  of the base mount  210 . In this case, the three groups of the light-emitting devices  300   a  are electrically connected in series. 
     Note that, the number of the group of the light-emitting devices  300   a  formed on the board-shaped base mount (base mount  210 ) is not limited to three, and may be two or four or more. 
     The LED module  200  is fixed by the lead wires  170   a  and  170   b  such that the main surface  211  of the base mount  210  faces toward the top of the globe  110 . 
       FIG. 6  is a diagram illustrating the configuration of a semiconductor light-emitting device  300  and the part around the semiconductor light-emitting device  300 . The semiconductor light-emitting device  300  is a face-up LED chip. 
     Note that, the semiconductor light-emitting device  300  is not limited to the face-up type, and may be an LED chip of face-down (flip-chip) type. Note that, the semiconductor light-emitting device  300  is not limited to an LED, and may be another device which emits light. 
     As illustrated in  FIG. 6 , the semiconductor light-emitting device  300  includes a sapphire board  310 , a nitride semiconductor part  320 , an anode  330   a  and a cathode  330   b.    
     The nitride semiconductor part  320  is formed on the sapphire board  310 . The nitride semiconductor part  320  includes nitride semiconductor layers  321 ,  322 , and  323 , each of which has a different composition. The nitride semiconductor layer  322  is a light-emitting layer (active layer) which emits light. 
     The anode  330   a  is formed on the nitride semiconductor part  320  (the nitride semiconductor layer  323 ). The cathode  330   b  is formed at an end portion of the nitride semiconductor layer  321 . 
     A wire bonding portion  331  is formed on the anode  330   a , and a wire bonding portion  332  is formed on the cathode  330   b . The wires  301  are electrically connected to the wire bonding portions  331  and  332 . Accordingly, the semiconductor light-emitting device  300  is supplied with power (voltage) through two wires  301 . 
     When power (voltage) is supplied between the anode  330   a  and the cathode  330   b , the light-emitting layer (nitride semiconductor layer  322 ) emits blue light. Part of the blue light is absorbed by the wavelength conversion material (phosphor) in the sealing part  220 , and is converted in to light in another wavelength. If the phosphor is a YAG phosphor, the blue light is converted into yellow light by the wavelength conversion material (phosphor). 
     The blue light not absorbed by the wavelength conversion material (phosphor) and the yellow light which is converted are diffused and mixed in the sealing part  220 . After that, the mixed light is emitted from the sealing part  220  as white light. 
     Since the base mount  210  is translucent, the white light emitted from the linear sealing part  220  transmits the inside of the base mount  210  and is emitted from the back surface and the side surfaces of the base mount  210 . 
     The sealing part containing the wavelength conversion material is arranged in a straight line on the main surface  211  of the base mount  210 . Accordingly, when the light bulb shaped lamp  100  is turned on, the sealing part  220  shines like a filament coil of a conventional incandescent light bulb when viewed from any side of the surface of the base mount  210 . 
     Note that, the sealing part  220  containing the wavelength conversion material may be provided on the back surface of the base mount  210  on which the semiconductor light-emitting devices  300  are not mounted. In this case, the white light is obtained by converting the blue light emitted from the back surface into the yellow light. 
     The sapphire board  310  is fixed to the main surface of the base mount  210  by the bonding material  302 . The semiconductor light-emitting device  300  is fixed to the main surface of the base mount  210  by the bonding material  302 . 
     The bonding material  302  is made of translucent material. The translucent material is, for example, a silicone resin containing filler made of metal oxide. Using the translucent material for the bonding material  302  can reduce the loss of light emitted from the side of the sapphire board  310  and the side surfaces of the sapphire board  310  in the semiconductor light-emitting device  300 , preventing the shadow cast by the bonding material  302 . 
     Note that, it is preferable that the base mount  210  is made of a material having a high thermal conductivity and high thermal emissivity in heat radiation. The material is referred to as a hard brittle material, which is a generic term for glass, ceramic, and others. 
     The emissivity is represented as a value between 0 and 1. 1 is a value representing the black body radiation. The emissivity of the glass or ceramic is in a range from 0.75 to 0.95, which is close to the black body radiation (1), although the value depends on the wavelength band or a state of surface. In terms of practical use, the emissivity of the base mount  210  is preferably 0.8 or higher, and is more preferably 0.9 or higher. 
     The volume of the LED module  200  is smaller than the entire light bulb shaped lamp  100 . Note that, when the heat capacity of the LED module  220  is small, a structure which increases the emissivity of the base mount  210  so as to radiate heat is preferable. 
     The wavelength conversion material contained in the sealing part  220  is not limited to a YAG phosphor. The wavelength conversion material may be a yellow phosphor such as (Sr,Ba) 2 SiO 4 :Eu 2+ , Sr 3 SiO 5 :Eu 2+ , for example. Alternatively, the wavelength conversion material may be a green phosphor such as (Ba,Sr) 2 SiO 4 : Eu 2+ , Ba 3 Si 6 O 12 N 2 : Eu 2+ . Alternatively, the wavelength conversion material may be a red phosphor such as CaAlSiN 3 :Eu 2+ , Sr 2 (Si,Al) 5 (N,O) 8 :Eu 2+ . 
     Note that, the material composing the sealing part  220  is not limited to a silicone resin. The material composing the sealing part  220  may be an organic material such as fluorine series resin or an inorganic material such as a low-melting-point glass or a sol-gel glass. Since the inorganic materials are more highly resistant to heat than the organic material, the sealing part  220  made of an inorganic material is advantageous to increase luminance. 
       FIG. 7  illustrates the configuration of the lighting circuit  180 . The lighting circuit  180  is a full-wave bridge rectification circuit. 
     As illustrated in  FIG. 7 , the lighting circuit  180  includes a diode bridge  181 , a capacitor  182 , a resistor  183 , and terminals  184   a ,  184   b ,  185   a , and  185   b.    
     The input terminals  181   a  and  181   b  of the diode bridge  181  are electrically connected to the terminals  184   a  and  184   b , respectively. The terminal  184   a  is electrically connected to a screw part  191 . The terminal  184   b  is electrically connected to an eyelet  192 . With this structure, when the base  190  is attached to a socket of a lighting apparatus not illustrated, the AC power is supplied to the terminals  184   a  and  184   b.    
     The resistor  183  is a resistor for adjusting the amount of current. An end of the resistor  183  is electrically connected to the terminal  185   a . An end of the capacitor  182  is electrically connected to the terminal  185   b.    
     The terminals  185   a  and  185   b  are electrically connected to the lead wires  170   a  and  170   b , respectively. The DC power (DC voltage) converted from the AC power by the diode bridge  181  and the capacitor  182  is supplied to the terminals  185   a  and  185   b.    
     Stated differently, the DC power (DC voltage) converted by the lighting circuit  180  is supplied to the lead wires  170   a  and  170   b.    
     Note that, the configuration of the lighting circuit  180  is not limited to the configuration including a smoothing circuit illustrated in  FIG. 7 . The lighting circuit  180  may be a circuit combining a dimming circuit, a boosting circuit, and others. 
     The following shall describe the structure for fixing the LED module included in the light bulb shaped lamp in detail. 
       FIG. 8  is a diagram for describing the fixing structure according to the embodiment 1. Here, the fixing structure refers to a structure for fixing the LED module (base mount). The fixing structure for the LED module  200  shall be described in the embodiment 1. 
     (a) in  FIG. 8  is a cross-sectional view illustrating the LED module  200  before being fixed and the lead wires  170   a  and  170   b  for fixing the LED module  200 . 
     (b) in  FIG. 8  is a cross-sectional view illustrating the LED module  200  before being fixed and the lead wires  170   a  and  170   b.    
     (c) in  FIG. 8  is a cross-sectional view of the LED module  200  supported (held) by the lead wires  170   a  and  170   b . As described before, each of the lead wires  170   a  and  170   b  may be simply referred to as the lead wire  170 . 
     As illustrated in  FIG. 4  and  FIG. 8 , the lead wire  170  includes the elastic part  17  which is elastic. 
     More specifically, the elastic part  17  is formed on each of the lead wires  170   a  and  170   b . The elastic part  17  is a part of each of the lead wires  170   a  and  170   b  formed in U-shape. To put it differently, the elastic part  17  is U-shaped. 
     Note that, as illustrated in (b) in  FIG. 8 , in each of the lead wires  170 , the shape of the part of each of the lead wires  170  closer to the end than the part in which the elastic part  17  is formed is straight before the lead wires  170  are fixed to the base mount  210 . In addition, the size of the elastic part  17  in the X-axis direction is larger than the diameter of the holes  250   a  and  250   b.    
     Accordingly, in the process for fixing each of the lead wires  170  to the base mount  210 , when the end portions of the lead wires  170  passes through the hole  250 , the uppermost part of the elastic part  17  contacts the base mount  210 . With this, the position of the base mount  210  in the globe  110  is fixed (see (b) in  FIG. 8 ). 
     Stated differently, the elastic part  17  in each of the lead wires  170  is capable of positioning the base mount  210  in the globe  110  in the process for fixing the lead wires  170  to the base mount  210 . 
     Note that, the shape of the elastic part  17  is not limited to the U-shape, and may be in other shape as long as the elastic part  17  is elastic. The elastic part  17  may be spring-shaped or a coil-shaped, for example. 
     The lead wire  170   a  is provided such that a part of the lead wire  170   a  passes through the hole  250   a  from the second surface which is opposite to the main surface  211  (the first surface) of the base mount  210  toward the main surface  211  (the first surface). The lead wire  170   b  is provided such that a part of the lead wire  170   b  passes through the hole  250   b  from the second surface which is opposite to the main surface  211  (the first surface) of the base mount  210  toward the main surface  211  (the first surface). 
     The end portion of the lead wire  170   a  in (b) in  FIG. 8  is bent toward the left-end semiconductor light-emitting device in the group of light-emitting devices  300   a  (see (c) in  FIG. 8 ). The end portion of the lead wire  170   a  is electrically connected to the wire  301  connected to the wire bonding portion  331  in the left-end semiconductor light-emitting device by solder or others, for example. 
     The end portion of the lead wire  170   b  in (b) in  FIG. 8  is bent toward the right-end semiconductor light-emitting device in the group of light-emitting devices  300   a  (see (c) in  FIG. 8 ). The end portion of the lead wire  170   b  is electrically connected to the wire  301  connected to the wire bonding portion  332  in the right-end semiconductor light-emitting device by solder or others, for example. 
     The lead wires  170   a  and  170   b  are electrically connected to the group of light-emitting devices  300   a  such that the DC power from the lighting circuit  180  can be supplied to the group of light-emitting group  300   a.    
     The elastic part  17  in each of the lead wires  170  is at least a part of the lead wire  170  not passing through the hole  250 . 
     Stated differently, the base mount  210  is supported by the elastic part  17  of each of the lead wires  170   a  and  170   b . Stated differently, the elastic part  17  is provided in the vicinity of the base mount  210 . 
     With this structure, for example, when the light bulb shaped lamp  100  as a product is transported by a truck, even if the light bulb shaped lamp  100  is shaken, the elastic part  17  absorbs the shake, and suppresses (reduces) the vibration transmitted to the base mount  210  (LED module  200 ). Accordingly, even if the light bulb shaped lamp is shaken, it is possible to suppress the possibility of malfunction caused by the shake. 
     Here, as a comparison, a light bulb shaped lamp having a structure in which the end portion of the lead wire and the base mount is connected by solder (hereafter referred to as a solder-connected lamp) shall be described as an example. Unlike the light bulb shaped lamp  100 , the lead wire of the solder-connected lamp does not have an elastic part. 
     In this case, if the solder-connected lamp is shaken, the vibration transmitted to the base mount is not suppressed. This is because the elastic part is not provided. Accordingly, the stress is exerted on the part connecting the lead wire and the base mount, and there is a possibility that the connection between the lead wire and the base mount are disconnected. Stated differently, the malfunction caused by the shake is that the light bulb shaped lamp  100  cannot be turned on due to disconnection between the lead wire and the base mount. 
     To put it another way, the malfunction caused by the shake is that the solder connecting the lead wire  170  to the base mount  210  comes off and no power is supplied to the semiconductor light-emitting device, resulting in the light bulb shaped lamp  100  unable to be turned on. 
     Accordingly, the light bulb shaped lamp  100  according to the embodiment 1 can suppress the possibility of the malfunction when the light bulb shaped lamp  100  is shaken. 
     The base mount  210  on which the semiconductor light-emitting device  300  is mounted is supported by the lead wires  170 . With this, it is possible to suppress the large part of the light emitted by the semiconductor light-emitting device  300  mounted on the base mount  210  being blocked. 
     Furthermore, the base mount  210  is translucent. Accordingly, the base mount  210  transmits the light emitted by the semiconductor light-emitting device  300  mounted on the base mount  210 . With this, it is possible to prevent the large part of the light emitted by the semiconductor light-emitting device  300  from being blocked. Accordingly, a sufficient light distribution angle can be achieved. 
     Note that, the elastic part  17  may be provided in the lead wire  170  at a position away from a predetermined distance from the base mount  210 . The predetermined distance corresponds to the length of the elastic part  17  in the Z-axis direction, for example.

     The shape of the base mount  210   a  is quadrangular prism or board. 
     Each of the holes  251   a  and  251   b  is a through hole passing though the board  210   a  from the main surface  211  (the first surface) of the base mount  210   a  toward the second surface which is opposite to the main surface  211 . In the following description, each of the holes  251   a  and  251   b  may be simply referred to as the hole  251  as well. Each of the holes  251  extends along the Z-axis direction. 
     (a) in  FIG. 9  is a cross-sectional view of the LED module  200 A fixed by the lead wires  174   a  and  174   b.    
     In the following description, each of the lead wires  174   a  and  174   b  may be simply referred to as the lead wire  174 . The fixing part  120  of the light bulb shaped lamp A 11  fixes the lead wire  174  such that a part of the lead wire  174  is exposed, in the same manner as the lead wire  170 . 
     The lead wire  174  is different from the lead wire  170  in  FIG. 4  in that a hole fixed part  20  is formed at an end portion of the lead wire  174 . Since the rest of the structure and function of the lead wire  174  are identical to those of the lead wire  170 , the detailed description shall not be repeated. The lead wires  174   a  and  174   b  correspond to the lead wires  170   a  and  170   b , respectively. 
     The LED module  200 A (the base mount  210   a ) is supported (held) by the lead wires  174   a  and  174   b.    
     More specifically, the hole fixed part  20  is formed at the end portion of each of the lead wires  174   a  and  174   b . The hole fixed part  20  is a part inserted into the hole  251  and fixed to the hole  251 . Stated differently, the hole fixed part  20  is a part which fixes the lead wire  174  to the base mount  210   a , using the hole  251 . 
     The hole fixed part  20  is a part in which the end portion of each of the lead wires  174   a  and  174   b  is formed in the shape illustrated in (a) and (c) in  FIG. 9 . 
     (b) in  FIG. 9  is a diagram illustrating the shape of the hole fixed part  20  before fixed to the LED module  200 A. As illustrated in (b) in  FIG. 9 , the hole fixed part  20  includes a plurality of leads  21  and a supporting part  23 . 
     Each of the leads  21  and the supporting part  23  is made of a material (metal) same as the material composing the lead wire  174 . The lead  21  is a bendable conductive metal. 
     The supporting part  23  is board-shaped. The size of the supporting part  23  in the X-axis direction is larger than the diameter of the holes  251   a  and  251   b . The lead  21  is fixed to the main surface of the supporting part  23 . 
     Accordingly, in the process for fixing each of the lead wires  174  to the base mount  210   a , when the leads  21  of each of the lead wire  174  pass through the hole  251  of the base mount  210   a , the upper surface (main surface) of the supporting part  23  contacts the base mount  210   a . With this, the position of the base mount  210   a  in the globe  110  is fixed. Stated differently, the supporting part  23  holds the part in the periphery of the hole  251  in the second surface opposite to the main surface  211  (the first surface) of the base mount  210   a.

     Note that, the structure is not limited to this structure, and the elastic part  17  may be provided at a position not contacting the supporting part  23 . 
     As illustrated in (a) and (c) in  FIG. 9 , the part of the leads  21  in the hole fixed part  20  projecting from the each of the holes  251  in the base mount  210   a  is crimped (bent) so as to contact the main surface  211  of the base mount  210   a.    
     Stated differently, a part of each of the leads  21  is crimped such that the lead  21  contacts the main surface  211  of the base mount  210   a  from the second surface opposite to the main surface (the first surface) of the base mount  210   a  to the main surface  211  (the first surface), through the hole  251 . 
     Furthermore, the lead wires  174   a  and  174   b  are electrically connected to the group of light-emitting devices  300   a  in the same manner as the embodiment 1 such that the DC power from the lighting circuit  180  can be supplied to the group of light-emitting devices  300   a.

When the conductive component  30  is metal, each of the holes  251   a  and  251   b  is filled with (press-fit) the conductive component  30 .

     The shape of the base mount  210   n  is quadrangular prism or board. 
     The LED module  200 N (the base mount  210   n ) is fixed (supported) by the lead wires  175   a  and  175   b . In the following description, each of the lead wires  175   a  and  175   b  may be simply referred to as the lead wire  175 . The fixing part  120  of the light bulb shaped lamp A 14  fixes the lead wire  175  such that a part of the lead wire  175  is exposed, in the same manner as the lead wire  170 . 
     The lead wire  175  is different from the lead wire  170  in  FIG. 4  in that a bent part  18  is formed at an end portion of the lead wire  175 . Since the rest of the structure and function of the lead wire  175  are identical to those of the lead wire  170 , the detailed description shall not be repeated.

     The four groups of light-emitting devices  300   a  that are not illustrated are formed on the base mount  210   b .

     Note that, the elastic parts  17  may be provided in the lead wires  170  and the fixing wires  162  at a position away from a predetermined distance from the base mount  210   b.

     As illustrated in  FIG. 21 , the LED module  200 C is different from the LED module  200 B in  FIG. 20  in that a base mount  210   c  is included instead of the base mount  210   b . The rest of the configuration of the LED module  200 C is identical to the LED module  200 B. Accordingly, the detailed description for the structure is not repeated. 
     The base mount  210   c  is different from the base mount  210   b  in that the holes  250   a ,  250   b ,  250   c , and  250   d  are not provided. The rest of the structure and the shape of the base mount  210   c  are identical to the base mount  210   b . Accordingly, the detailed description shall not be repeated.

     Note that, the four groups of light-emitting devices  300   a  formed on the base mount  210   c  are electrically connected in series such that the current flows through the current path PL 2 , for example. 
     In the same manner as the fixing structure according to the variation 6 of the embodiment 1, the LED module  200 C is fixed by the lead wires  175   a  and  175   b  and the fixing wires  161   a  and  161   b . Stated differently, each of the end portions of the base mount  210   c  in the LED module  200 C are fixed by one of the lead wires  175  or the fixing wires  161  clipping the end portion. Stated differently, the elastic parts  17  of the lead wires  175  and the fixing wires  161  are provided in the vicinity of the base mount  210   c.    
     Since the structure and function of the fixing wires  175   a  and  175   b  and the fixing wires  161   a  and  161   b  are described above, the detailed description is not repeated.

     Note that, the elastic parts  17  may be provided in the lead wire  175  and the fixing wire  161  at a position away from a predetermined distance from the base mount  210   c.    
     Variation 14 of Embodiment 1 
       FIG. 22  is a diagram for describing the fixing structure according to the variation 14 of the embodiment 1. The fixing structure for the LED module  200 C shall be described in the variation 14 of the embodiment 1. 
     In the following description, a light bulb shaped lamp according to the variation 14 of the embodiment 1 may be referred to as a light bulb shaped lamp A 114 . The light bulb shaped lamp A 114  is different from the light bulb shaped lamp A 111  according to the variation 11 of the embodiment 1 illustrated in  FIG. 19  in that the LED module  200 C is included instead of the four LED modules  200 N integrated. The rest of the structure of the light bulb shaped lamp A 114  is identical to the light bulb shaped lamp A 111 . Accordingly, the description for the structure shall be omitted. 
     As shown in  FIG. 22 , the LED module  200 C is fixed by the fixing structure as illustrated in  FIG. 19  described in the variation 11 of the embodiment 1. Stated differently, the LED module  200 C is fixed by the end portion fixing parts  40   a ,  40   b ,  40   c , and  40   d , the lead wires  170   a  and  170   b , and the fixing wires  160   a  and  160   b , in the same manner as the integrated base mount in  FIG. 19 . Stated differently, the elastic parts  17  of the lead wires  170  and the fixing wires  160  are provided in the vicinity of the base mount  210   c.    
     Note that, the four groups of light-emitting devices  300   a  formed on the base mount  210   c  are electrically connected in series such that the current flows through the current path PL 2 , for example. 
     With this configuration, even if the base mount is cross-shaped, the LED module  200 C (the base mount  210   c ) is fixed firmly, according to the configuration of the variation 14 of the embodiment 1. 
     Each of the lead wires  170  and the fixing wires  160  has the elastic part  17 . Accordingly, the same effect achieved by the embodiment 1 is achieved.

     Note that, the elastic parts  17  may be provided in the lead wires  170  and the fixing wires  160  at a position away from a predetermined distance from the base mount  210   c.    
     Embodiment 2 
     (Overall Structure of Light Bulb Shaped Lamp) 
     The overall structure of the light bulb shaped lamp  100 A according to the embodiment 2 shall be described with reference to  FIG. 23  to  FIG. 25 . 
       FIG. 23  is a perspective view of the light bulb shaped lamp according to the embodiment 2. 
       FIG. 24  is an exploded perspective view of the light bulb shaped lamp according to the embodiment 2. 
       FIG. 25  is a front view of the light bulb shaped lamp according to the embodiment 2. 
     The light bulb shaped lamp  100 A is different from the light bulb shaped lamp  100  in  FIG. 1  in that lead wires  130   a  and  130   b  are provided instead of the lead wires  170   a  and  170   b , and an LED module  200 N is provided instead of the LED module  200 . The rest of the structure of the light bulb shaped lamp  100 A is identical to the light bulb shaped lamp  100 . Accordingly, the detailed description is not repeated. 
     The lead wires  130   a  and  130   b  have the same structure and function as the lead wires  170   a  and  170   b . Accordingly, the detailed description for the lead wires  130   a  and  130   b  is omitted. 
     Note that, in  FIG. 25 , the lighting circuit  180  and part of lead wires  130   a  and  130   b  for power supply and for support which are positioned inside the base  190  are illustrated in dotted lines. 
     The LED module  200 N is electrically connected to the lead wires  130   a  and  130   b.    
     The lead wire  130   a  is a composite wire including an internal lead wire  13   a , the Dumet wire  172   a , and the external lead wire  173   a  joined in order. The lead wire  130   b  is a composite wire including an internal lead wire  13   b , the Dumet wire  172   b , and the external lead wire  173   b  joined in order. 
     In the following description, each of the lead wire  130   a  and  130   b  may be simply referred to as the lead wire  130 . Furthermore, in the following description, each of the internal lead wires  13   a  and  13   b  may be simply referred to as the internal lead wire  13 . 
     The internal lead wire  13  is an electric wire extending from the fixing part  120  to be described later to the LED module  200 N. The internal lead wire  13  is joined with the base mount  210   n  to be described later, and supports the LED module  200 N (the base mount  210   n ). Stated differently, the base mount  210   n  to be described later is supported by the lead wires  130   a  and  130   b.    
     In addition, two lead wires  130  do not have to be provided. For example, when the light bulb shaped lamp  100 A includes a plurality of the LED modules  200 N in the globe  110 , two lead wires  130  may be provided for each of the LED modules  200 N. Accordingly, the light bulb shaped lamp  100 A may include the lead wires  130  twice in number as the number of the LED modules  200 N. 
     Among the internal lead wire  13 , the Dumet wire  172 , and the external lead wire  173  composing the lead wire  130 , the fixing part  120  seals the Dumet wire  172 . To put it differently, the fixing part  120  fixes the lead wire  130  exposing a part of the lead wire  130  (the internal lead wire  13 ). 
     The globe  110  covers the LED module  200 N, part of the lead wires  130   a  and  130   b , a part of the fixing part  120 , and others. The LED module  200 N is positioned at a part around the center of the globe  110 . The globe  110  is made of a translucent material, as described above. 
     With this, the light bulb shaped lamp  100 A can reduce the loss of light emitted by the semiconductor light-emitting device  300  caused by the globe  110 . 
     The light from the LED module  200 N passes through the globe  110 , and is emitted to outside. 
     Since the LED module  200 N is positioned around the center of the globe  110 , omnidirectional light distribution property is achieved when the LED module  200 N emits light. 
     The lighting circuit  180  is electrically connected to the lead wires  130   a  and  130   b.    
     (The Configuration of LED Module) 
       FIG. 26  is a cross-sectional view illustrating the configuration of the LED module  200 N. Note that, the lead wires  130   a  and  130   b  not included in the LED module  200 N are also illustrated in  FIG. 26 . 
     Note that, the details on the shape of the lead wires  130   a  and  130   b  shall be described later. 
     The LED module  200 N is housed in the globe  110 , and is preferably positioned at the center of the sphere defined by the globe  110 . With this structure, the light bulb shaped lamp  100 A can achieve omnidirectional light distribution property when the light bulb shaped lamp  100  is switched on. The omnidirectional light distribution property is approximated to a common incandescent light bulb using conventional filament coil. 
     As shown in  FIG. 26 , the LED module  200 N includes the base mount  210   n  described above, a plurality of semiconductor light-emitting devices  300 , and a sealing part  220 . 
     The shape of the base mount  210   n  is a quadrangular prism, as illustrated in (a) in  FIG. 27 . 
     Note that, the shape of the base mount  210   n  is not limited to the quadrangular prism, and may be other shape. The shape of the base mount  210   n  may be like a board, as illustrated in  FIG. 27  ( b ). 
     If the shape of the base mount  210   n  is a quadrangular prism, the LED module  200 N in the light bulb shaped lamp  100 A can imitate the filament of an incandescent light bulb. 
     End portions of the lead wires  130   a  and  130   b  are fixed to the power supply terminals  241   a  and  241  by solder, respectively. Accordingly, the lead wires  130   a  and  130   b  are electrically connected to the power supply terminals  241   a  and  241 , respectively. To put it differently, the lead wires  130   a  and  130   b  are fixed to the base mount  210   n  (the LED module  200 N) by solder. 
     The base mount  210   n  has a main surface  211 . The semiconductor light-emitting devices  300  are mounted in a straight line on the main surface  211 . Stated differently, the semiconductor light-emitting devices  300  are mounted on the main surface  211  of the base mount  210   n  such that the semiconductor light-emitting devices  300  are arranged in a straight line between the power supply terminal  241   a  and the power supply terminal  241   b.    
     The group of light-emitting devices  300   a  is formed of the semiconductor light-emitting devices  300  mounted on the main surface  211  on the base mount  210   n  in a straight line. The power is supplied to the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  from the lead wires  130   a  and  130   b.    
     To put it differently, the lead wires  130   a  and  130   b  are electric wires for supplying power to the semiconductor light-emitting devices  300 . More specifically, the lead wires  130   a  and  130   b  are electric wires for supplying power to the LED module  200 N as the light-emitting module. 
     Note that, if the shape of the base mount  210   n  is a quadrangular prism, the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  may be formed on a side surface of the base mount  210   n  different from the main surface  211 . 
     Note that, as illustrated in  FIG. 27  ( b ), if the base mount  210   n  is board-shaped, three sealing parts  220  for sealing the group of light-emitting devices  300   a  are formed on the main surface  211 . Accordingly, three groups of light-emitting devices  300   a  are formed on the main surface  211  of the base mount  210   n . In this case, the three groups of the light-emitting devices  300   a  are electrically connected in series. 
     The LED module  200 N is fixed by the lead wires  130   a  and  130   b  such that the main surface  211  of the base mount  210   n  faces toward the top of the globe  110 . 
     Since the base mount  210   n  is translucent, the white light emitted from the linear sealing part  220  is transmitted through the inside of the base mount  210   n  and is emitted from the back surface and the side surfaces of the base mount  210   n.    
     Note that, the sealing part  220  containing the wavelength conversion material may be provided on the back surface of the base mount  210   n  on which the semiconductor light-emitting devices  300  are not mounted. 
     The following shall describe the structure for fixing the LED module included in the light bulb shaped lamp in detail. 
     The fixing structure according to the embodiment 2 shall be described with reference to  FIG. 26 . The fixing structure for the LED module  200 N shall be described in the embodiment 2. 
     More specifically, the end portion of each of the lead wires  130   a  and  130   b  has a bent part  18  having a shape which allows the bent part  18  to clip the end portion of the base mount. The bent part  18  is an end portion clipping part clipping the end portion of the base mount. The bent part  18  is an end portion of each of the lead wires  130   a  and  130   b  formed in U-shape. 
     Stated differently, each of the end portion clipping parts (bend parts  18 ) is a bent part formed by bending the end portion of the lead wire corresponding to the end portion clipping part. To put it differently, the bent part  18  as the end portion clipping part is a bent part of the end portion of the lead wire. The bent portion  18  is U-shaped. 
     Note that, the shape of the bent portion  18  is not limited to U-shape, but may be square U-shape. 
     As illustrated in  FIG. 26 , the lead wire  130   a  is provided such that the bent part  18  in the lead wire  130   a  clips one of the two end portions of the base mount  210   n  orthogonal to the X-axis direction. The lead wire  130   b  is provided such that the bent portion  18  in the lead wire  130   b  clips the other of the two end portions of the base mount  210   n  orthogonal to the X-axis direction. 
     More specifically, at the end portion of each of the lead wires  130 , the bent part  18  as the end portion clipping part is formed. Each of the bent parts  18  in the lead wires  130  clips one of the end portions of the base mount  210   n . More specifically, the end portion clipping parts (the bent parts  18 ) formed in the lead wires  130  clips the end portions of the base mount  210   n . Accordingly, at least two end portions of the base mount  210   n  clipped by the bent parts  18  are parallel to the same direction (Y-axis direction). 
     Stated differently, the base mount  210   n  is fixed by the clipping by the bent parts  18  in the lead wires  130   a  and  130   b . Stated differently, the base mount  210   n  to be described later is supported by the lead wires  130   a  and  130   b . Accordingly, the base mount  210   n  is clipped and supported by the bent parts  18  (end portion clipping parts) in the lead wires  130   a  and  130   b.    
     The lead wires  130   a  and  130   b  are electrically connected to the group of light-emitting devices  300   a  such that the DC power from the lighting circuit  180  can be supplied to the group of light-emitting devices  300   a.    
     With the structure described above, the base mount  210   n  on which the semiconductor light-emitting device is mounted is supported by the lead wire having the end portion clipping part (the bent part  18 ) clipping the end portions of the base mount  210   n  at the end portion. Stated differently, the base mount  210   n  is fixed by the clipping by the bent parts  18  in the lead wires  130   a  and  130   b.    
     Accordingly, the base mount  210   n  is fixed firmly by the lead wires  130   a  and  130   b  clipping the end portions of the base mount  210   n . Accordingly, the base mount on which the semiconductor light-emitting device is mounted is fixed firmly. 
     Note that, in the embodiment, each of the left end portion and the right end portion of the base mount  210   n  is fixed by one lead wire having the bent part  18 . However, it is not limited to this example. For example, each of the left end portion and the right end portion of the base mount  210   n  may be fixed by a plurality of lead wires each having the bent part. 
     The base mount  210   n  on which the semiconductor light-emitting device  300  is mounted is supported by the lead wires  130 . With this, it is possible to suppress the large part of the light emitted by the semiconductor light-emitting device  300  mounted on the base mount  210   n.    
     Furthermore, the base mount  210   n  is translucent. With this, it is possible to prevent the large part of the light emitted by the semiconductor light-emitting device  300  from being blocked. Accordingly, a sufficient light distribution angle can be achieved. 
     Variation 1 of Embodiment 2 
       FIG. 28  is a cross-sectional view for describing the fixing structure according to the variation 1 of the embodiment 2. The fixing structure for the LED module  200 N shall be described in the variation 1 of the embodiment 2.

     Here, the shape of each of the main surfaces  211  of the multiple base mounts  210   n  is quadrilateral. Furthermore, each of the end portion fixing parts  40  as the end portion clipping part clips a part corresponding to a side of a quadrilateral in a different base mount. 
     More specifically, the end portion fixing part  40  as the end portion clipping part clipping a different end portion of the multiple base mount integrated is formed at the end portion of the lead wire  132   a  or  132   b . The end portion fixing part  40  as the end portion clipping part clipping the end portion of at least one of the multiple base mounts integrated is formed at the end of the lead wire  132 . 
     Accordingly, the multiple base mounts integrated are supported by at least two lead wires. Accordingly, at least one of the multiple bases integrated is supported by the end portion fixing parts  40  in one of the at least two lead wires clipping the base. 
     The lead wires  132   a  and  132   b  are electrically connected to the group of light-emitting devices  300   a  such that the DC power from the lighting circuit  180  can be supplied to the groups of light-emitting devices  300   a  corresponding to the base mount  210   na ,  210   nb ,  210   nc , and  210   nd  through the end portion fixing parts  40   a  and  40   b . With this, the four groups of light-emitting devices  300   a  emits light by the flow of current through the current path PL 2  in (b) in  FIG. 35 .

     Embodiment 3 
     (Overall Structure of Light Bulb Shaped Lamp) 
     The overall structure of the lightbulb-shaped lamp  100 B according to the embodiment 3 shall be described with reference to  FIG. 38  to FIG.  40 . 
       FIG. 38  is a front view of the lightbulb-shaped lamp according to the embodiment 3. 
       FIG. 39  is an exploded perspective view of the lightbulb-shaped lamp according to the embodiment 3. 
       FIG. 40  is a perspective view of the lightbulb-shaped lamp according to the embodiment 3. 
     The lightbulb-shaped lamp  100 B is different from the lightbulb-shaped lamp  100  in  FIG. 1  in that lead wires  140   a  and  140   b  are provided instead of the lead wires  170   a  and  170   b , and an LED module  201 A instead of the LED module  200 . The rest of the structure of the lightbulb-shaped lamp  100 B is identical to the lightbulb-shaped lamp  100 . Accordingly, the detailed description is not repeated. 
     The lead wires  140   a  and  140   b  have the same structure and function as the lead wires  170   a  and  170   b . Accordingly, the detailed description for the lead wires  140   a  and  140   b  is omitted. 
     Note that, in  FIG. 40 , the lighting circuit  180  and part of lead wires  140   a  and  140   b  for power supply and for support which are positioned inside a base  190  are illustrated in dotted lines. 
     The LED module  201 A is electrically connected to the lead wires  140   a  and  140   b.    
     The lead wire  140   a  is a composite wire including an internal lead wire  141   a , a Dumet wire  172   a , and an external lead wire  173   a  joined in order. The lead wire  140   b  is a composite wire including an internal lead wire  141   b , a Dumet wire  172   b , and an external lead wire  173   b  joined in order. 
     In the following description, the lead wire  140   a  and  140   b  are simply referred to as the lead wire  140 . Furthermore, in the following description, each of the internal lead wires  141   a  and  141   b  may be simply referred to as the internal lead wire  141 . 
     The internal lead wire  141  is an electric wire extending from the fixing part  120  to the LED module  201 A. The internal lead wire  141  is joined with the base mount  210   a , and supports the LED module  201 A (the base mount  210   a ). Stated differently, the base mount  210   a  to be described later is supported by the lead wires  140   a  and  140   b.    
     In addition, two lead wires  140  do not have to be provided. For example, when the lightbulb-shaped lamp  100 B includes a plurality of the LED modules  201 A in the globe  110 , two lead wires  140  may be provided for each of the LED modules  201 A. Accordingly, the lightbulb-shaped lamp  100 B may include the lead wires  140  twice in number as the number of the LED modules  201 A. 
     Among the internal lead wire  141 , the Dumet wire  172 , and the external lead wire  173  composing the lead wire  140 , the fixing part  120  seals the Dumet wire  172 . To put it differently, the fixing part  120  fixes the lead wire  140  exposing a part of the lead wire  140  (the internal lead wire  141 ). 
     The globe  110  covers the LED module  201 A, part of the lead wires  140   a  and  140   b , a part of the fixing part  120 , and others. The LED module  201 A is positioned at a part around the center of the globe  110 . The globe  110  is made of a translucent material, as described above. 
     With this, the lightbulb-shaped lamp  100 B can reduce the loss of light emitted by the semiconductor light-emitting device  300  caused by the globe  110 . 
     The light from the LED module  201 A passes through the globe  110 , and is emitted to outside. 
     Since the LED module  201 A is positioned around the center of the globe  110 , omnidirectional light distribution property is achieved when the LED module  201 A emits light. 
     The lighting circuit  180  is electrically connected to the lead wires  140   a  and  140   b.    
     (The Configuration of LED Module) 
       FIG. 41  is a cross-sectional view illustrating the configuration of the LED module  201 A. Note that, the lead wires  140   a  and  140   b  not included in the LED module  201 A are also illustrated in  FIG. 41 . 
     Note that, the details on the shape of the lead wires  140   a  and  140   b  shall be described later. 
     The LED module  201 A is different from the LED module  200  illustrated in  FIG. 4  in that a base mount  210   a  is included instead of the base mount  210 . The rest of the configuration of the LED module  200 A is identical to the LED module  200 . Accordingly, the detailed description is not repeated. 
     The LED module  201 A is housed in the globe  110 , and is preferably positioned at the center of the sphere defined by the globe  110 . With this structure, the light bulb shaped lamp  100 B can achieve omnidirectional light distribution property when the light bulb shaped lamp  100  is switched on. The omnidirectional light distribution property is approximated to a common incandescent light bulb using conventional filament coil. 
     As shown in  FIG. 41 , the LED module  201 A includes the base mount  210   a , a plurality of semiconductor light-emitting devices  300 , and a sealing part  220 . 
     The shape of the base mount  210   a  is a quadrangular prism, as illustrated in (a) in  FIG. 42 . 
     Note that, the shape of the base mount  210   a  is not limited to the quadrangular prism, and may be other shape. The shape of the base mount  210   a  may be board-shaped, as illustrated in (b) in  FIG. 42 . 
     If the shape of the base mount  210   a  is a quadrangular prism, the LED module  201 A in the lightbulb-shaped lamp  100 B can imitate the filament of an incandescent lightbulb. 
     Each of the lead wires  140   a  and  140   b  is connected to the conductive component  30 . Each of the conductive components  30  is connected to the power supply terminal  241   a  or the power supply terminal  241   b  by solder. Accordingly, the lead wires  140   a  and  140   b  are electrically connected to the power supply terminals  241   a  and  241 , respectively. To put it differently, the lead wires  140   a  and  140   b  are fixed to the base mount  210   a  (the LED module  201 A) by solder. 
     The base mount  210  has a main surface  211 . The semiconductor light-emitting devices  300  are mounted in a straight line on the main surface  211 . Stated differently, the semiconductor light-emitting devices  300  are mounted on the main surface  211  of the base mount  210   a  such that the semiconductor light-emitting devices  300  are arranged in a straight line between the power supply terminal  241   a  and the power supply terminal  241   b.    
     The group of light-emitting devices  300   a  is formed of the semiconductor light-emitting devices  300  mounted on the main surface  211  on the base mount  210   a  in a straight line. The power is supplied to the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  from the lead wires  140   a  and  140   b.    
     To put it differently, the lead wires  140   a  and  140   b  are electric wires for supplying power to the semiconductor light-emitting devices  300 . More specifically, the lead wires  140   a  and  140   b  are electric wires for supplying power to the LED module  201 A as the light-emitting module. 
     Note that, if the shape of the base mount  210   a  is a quadrangular prism, the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  may be formed on a side surface of the base mount  210   a  different from the main surface  211 . 
     As illustrated in  FIG. 41  and  FIG. 42 , holes  251   a  and  251   b  are provided on the ends of the base mount  210   a  in the longer direction (X-axis direction). Each of the holes  251   a  and  251   b  is a through hole passing through the base mount  210   a . Stated differently, the base mount  210   a  has the holes  251   a  and  251   b  passing through the base mount  210   a . Each of the holes  251   a  and  251   b  extends along the Z-axis direction. 
     In the following description, each of the holes  251   a  and  251   b  may be simply referred to as the hole  251  as well. 
     Note that, as illustrated in (b) in  FIG. 42 , if the base mount  210   a  is board-shaped, three sealing parts  220  for sealing the groups of light-emitting devices  300   a  are formed on the main surface  211 , for example. Accordingly, three groups of light-emitting devices  300   a  are formed on the main surface  211  of the base mount  210   a . In this case, the three groups of the light-emitting devices  300   a  are electrically connected in series. 
     The LED module  201 A is fixed by the lead wires  140   a  and  140   b  such that the main surface  211  of the base mount  210   a  faces toward the top of the globe  110 . 
     Since the base mount  210   a  is translucent, the white light emitted from the linear sealing part  220  transmits the inside of the base mount  210   a  and is emitted from the back surface and the side surfaces of the base mount  210   a.    
     Note that, the sealing part  220  containing the wavelength conversion material may be provided on the back surface on which the semiconductor light-emitting devices  300  are not mounted in the base mount  210   a.    
     The following shall describe the structure for fixing the LED module included in the light bulb shaped lamp in detail. 
     The fixing structure according to the embodiment 3 shall be described with reference to  FIG. 41 . The fixing structure for the LED module  201 A shall be described in the embodiment 3. 
     As illustrated in  FIG. 41 , the conductive component  30  is filled in the holes  251   a  and  251   b  in the base mount  210   a.    
     The conductive component  30  is, for example, metal such as stainless, cermet, or others. When the conductive component  30  is metal, each of the holes  251   a  and  251   b  is filled (press-fit) with the conductive component  30 . 
     When the conductive component  30  is composed of cermet, each of the holes  251   a  and  251   b  is filled with the conductive component  30  by the thermal shrink-fit. Stated differently, the conductive component  30  in this case is made of cermet. 
     The conductive component  30  filled in the hole  251   a  is electrically connected to the wire bonding part  331  of the left-end semiconductor light-emitting device in the group of light-emitting devices  300   a  by a wire  301  which is not illustrated. The conductive component  30  filled in the hole  251   b  is electrically connected to the wire bonding part  332  of the right-end semiconductor light-emitting device in the group of light-emitting devices  300   a  by the wire  301 . 
     As illustrated in  FIG. 41 , the end portions of the lead wires  140   a  and  140   b  are bent so as to form parts parallel to the second surface of the base mount  210   a , and the parts of the end portions parallel to the second surface are welded to the conductive components  30  by laser, for example. Stated differently, the end portion of each of the lead wires  140  is angled so as to form a part parallel to the second surface of the base mount  210   a , and a part of the end portion of each of the lead wires  140  is connected to the conductive component  30 . The lead wire  140  is connected to the conductive component  30 . 
     Stated differently, the lead wire  140  is electrically connected to the conductive component  30  from the side of the second surface opposite to the main surface  211  (the first surface) of the base mount  210   a . Accordingly, the LED module  201 A (the base mount  210   a ) is held (supported) by the lead wires  140   a  and  140   b  connected to the conductive component  30 . 
     With this, the lead wire  140   a  is electrically connected to the left-end semiconductor light-emitting device in the group of light-emitting devices  300   a  through the conductive component  30 . Furthermore, the lead wire  140   b  is electrically connected to the right-end semiconductor light-emitting device in the group of light-emitting devices  300   a  through the conductive component  30 . 
     The lead wires  140   a  and  140   b  are electrically connected to the group of light-emitting devices  300   a  such that the DC power from the lighting circuit  180  can be supplied to the group of light-emitting group  300   a.    
     With the configuration described above, the conductive component  30  filled in the hole  251  in the base mount  210   a  is firmly fixed to the base mount  210   a . The base mount  210   a  on which the semiconductor light-emitting devices  300  are mounted is supported by the lead wire  140  connected to the conductive component  30  filled in the hole  251  in the base mount  210   a . Accordingly, the base mount  210   a  is fixed firmly by the lead wires  140   a  and  140   b . Accordingly, the base mount on which the semiconductor light-emitting device is mounted is fixed firmly. 
     The base mount  210   a  on which the semiconductor light-emitting device  300  is mounted is supported by the lead wires  140 . With this, it is possible to suppress the large part of the light emitted by the semiconductor light-emitting device  300  mounted on the base mount  210   a.    
     Furthermore, the base mount  210   a  is translucent. With this, it is possible to prevent the large part of the light emitted by the semiconductor light-emitting device  300  from being blocked. Accordingly, a sufficient light distribution angle can be achieved.

Stated differently, the end portion of each of the lead wires  140  is angled so as to form a part parallel to the second surface of the base mount  210   a , and the part of the end portion of each of the lead wires  140  parallel to the second surface is connected to the conductive component  31 . The lead wire  140  is connected to the conductive component  31 . 
     Stated differently, the lead wire  140  is electrically connected to the conductive component  31  from the side of the second surface opposite to the main surface  211  (the first surface) of the base mount  210   a . Accordingly, the LED module  202 A (the base mount  210   a ) is held (supported) by the lead wires  140   a  and  140   b  connected to the conductive component  31 . 
     With this, the lead wire  140   a  is electrically connected to the left-end semiconductor light-emitting device in the group of light-emitting devices  300   a  through the conductive component  31 . Furthermore, the lead wire  140   b  is electrically connected to the right-end semiconductor light-emitting device in the group of light-emitting devices  300   a  through the conductive component  31 . 
     The lead wires  140   a  and  140   b  are electrically connected to the group of light-emitting devices  300   a  such that the DC power from the lighting circuit  180  can be supplied to the group of light-emitting group  300   a.    
     With the configuration described above, the conductive component  31  filled in the hole  251  in the base mount  210   a  is firmly fixed to the base mount  210   a . The base mount  210   a  on which the semiconductor light-emitting devices  300  are mounted is supported by the lead wire  140  connected to the conductive component  31  filled in the hole  251  in the base mount  210   a . Accordingly, the base mount  210   a  is fixed firmly by the lead wires  140   a  and  140   b .

     The variation 2 of the embodiment 3 is different from the structure in the Embodiment 3 illustrated in  FIG. 41  in that the base mount  210   a  is fixed by a rod part  120   a  of the fixing part  120  as the stem as well. The structure other than the structure for fixing the base mount  210   a  is identical to the embodiment 3. Accordingly, the detailed description for the structure shall not be repeated. 
     As described above, the fixing part  120  as the stem is provided on a side (the second surface) opposite to the main surface  211  of the base mount  210   a.

     Note that, the fixing structure according to the variation 2 of the embodiment 3 may be applied to the fixing structure according to the variation 1 of the embodiment 3 illustrated in  FIG. 43 . More specifically, the base mount  210   a  in the LED module  202 A may be fixed by the rod part  120   a  of the fixing part  120 . 
     In addition, the shape of the fixing part  120  may allow the tip of the rod part  120   a  of the fixing part  120  to contact the surface opposite to the main surface  211  of the base mount  210   a . In this case, the adhesive  122  may not be necessary.

The internal lead wire  151  is joined with the base mount  210   a , and supports the LED module  200 A (the base mount  210   a ). Stated differently, the base mount  210   a  to be described later is supported by the lead wires  150   a  and  150   b.    
     In addition, two lead wires  150  do not have to be provided. For example, when the lightbulb-shaped lamp  100 C includes a plurality of the LED modules  200 A in the globe  110 , two lead wires  150  may be provided for each of the LED modules  200 A. Accordingly, the lightbulb-shaped lamp  100 C may include the lead wires  150  twice in number as the number of the LED modules  200 A. 
     Among the internal lead wire  151 , the Dumet wire  172 , and the external lead wire  173  composing the lead wire  150 , the fixing part  120  seals the Dumet wire  172 . To put it differently, the fixing part  120  fixes the lead wire  150  exposing a part of the lead wire  150  (the internal lead wire  151 ). 
     The globe  110  covers the LED module  200 A, part of the lead wires  150   a  and  150   b , a part of the fixing part  120 , and others. The LED module  200 A is positioned at a part around the center of the globe  110 . The globe  110  is made of a translucent material, as described above. 
     With this, the lightbulb-shaped lamp  100 C can reduce the loss of light emitted by the semiconductor light-emitting device  300  caused by the globe  110 . 
     The light from the LED module  200 A passes through the globe  110 , and is emitted to outside. 
     Since the LED module  200 A is positioned around the center of the globe  110 , omnidirectional light distribution property is achieved when the LED module  200 A emits light. 
     The lighting circuit  180  is electrically connected to the lead wires  150   a  and  150   b.    
     (The Configuration of LED Module) 
       FIG. 49  is a cross-sectional view illustrating the configuration of the LED module  200 A. Note that, the lead wires  150   a  and  150   b  not included in the LED module  200 A are also illustrated in  FIG. 49 . 
     Note that, the details on the shape of the lead wires  150   a  and  150   b  shall be described later. 
     The LED module  200 A is different from the LED module  200  illustrated in  FIG. 4  in that a base mount  210   a  is included instead of the base mount  210 . The rest of the configuration of the LED module  200 A is identical to the LED module  200 . Accordingly, the detailed description is not repeated. 
     The LED module  200 A is housed in the globe  110 , and is preferably positioned at the center of the sphere defined by the globe  110 . With this structure, the light bulb shaped lamp  100 A can achieve omnidirectional light distribution property when the light bulb shaped lamp  100  is switched on. The omnidirectional light distribution property is approximated to a common incandescent light bulb using conventional filament coil. 
     As shown in  FIG. 49 , the LED module  200 A includes the base mount  210   a  described above, a plurality of semiconductor light-emitting devices  300 , and a sealing part  220 . 
     The structure of the base mount  210   a  has been illustrated using  FIG. 42 . Accordingly, the detailed description for the integrated structure is not repeated. 
     The hole fixed part  20  to be described later is formed at the end portion of each of the lead wires  150   a  and  150   b . Each of the conductive components  20  is connected to the power supply terminal  241   a  or the power supply terminal  241   b  by solder. Accordingly, the lead wires  150   a  and  150   b  are electrically connected to the power supply terminals  241   a  and  241 , respectively. To put it differently, the lead wires  150   a  and  150   b  are fixed to the base mount  210   a  (the LED module  200 A) by solder. 
     The power is supplied to the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  from the lead wires  150   a  and  150   b.    
     To put it differently, the lead wires  150   a  and  150   b  are electric wires for supplying power to the semiconductor light-emitting devices  300 . More specifically, the lead wires  150   a  and  150   b  are electric wires for supplying power to the LED module  200 A as the light-emitting module. 
     Note that, if the shape of the base mount  210   a  is a quadrangular prism, the semiconductor light-emitting devices  300  composing the group of light-emitting devices  300   a  may be formed on a side surface of the base mount  210   a  different from the main surface  211 . 
     The LED module  200 A is fixed by the lead wires  150   a  and  150   b  such that the main surface  211  of the base mount  210   a  faces toward the top of the globe  110 . 
     Since the base mount  210   a  is translucent, the white light emitted from the linear sealing part  220  transmits the inside of the base mount  210   a  and is emitted from the back surface and the side surfaces of the base mount  210   a.    
     The following shall describe the structure for fixing the LED module included in the light bulb shaped lamp in detail. 
       FIG. 50  is a diagram for describing the fixing structure according to the embodiment 4. The fixing structure for the LED module  200 A shall be described in the embodiment 4. 
     The fixing structure according to the embodiment 4 shall be described with reference to  FIG. 49  and  FIG. 50 . 
     (a) in  FIG. 50  is an enlarged view of the LED module  200 A fixed by the lead wires  150   a  and  150   b.    
     (b) in  FIG. 50  is a diagram illustrating the shape of the hole fixed part  20  before fixed to the LED module  200 A. 
     (c) in  FIG. 50  is a diagram illustrating the shape of the hole fixed part  20  before fixed to the LED module  200 A. 
     As illustrated in  FIG. 49  and  FIG. 50 , the hole fixed parts  20  are formed at the end of the lead wires  150   a  and  150   b . The hole fixed part  20  is a part inserted into the hole  251  and fixed to the hole  251 . Stated differently, the hole fixed part  20  is a part for fixing the lead wire  150  with the base mount  210   a , using the hole  251 . 
     The hole fixed parts  20  are end portions of the lead wires  150   a  and  150   b  formed into shapes of the hole fixed part  20  illustrated in  FIG. 49 , (a) in  FIG. 50  and (c) in  FIG. 50 . Stated differently, the hole fixed part  20  and the lead wire  150  are integrally formed. 
     Note that, the hole fixed part  20  and the lead wire  150  are not limited to the integrally formed structure. For example, the hole fixed part  20  may be weld to the end of the lead wire  150 . 
     As illustrated in (b) in  FIG. 50 , the hole fixed part  20  includes four leads  21  and a supporting part  23 . 
     Each of the leads  21  and the supporting part  23  are composed of the same material (metal) as the material composing the lead wire  170 . The lead  21  is a bendable conductive metal. 
     The supporting part  23  is board-shaped. The size of the supporting part  23  in the X-axis direction is larger than the diameter of the holes  251   a  and  251   b . Each lead  21  is formed on the main surface of the supporting part  23 . 
     Accordingly, when fixing each lead  150  with the base mount  210   a , the lead  21  in each lead wire  150  passes through the hole  251  in the base mount  210   a , the position of the base mount  210   a  in the globe  110  is fixed by the upper surface (main surface) of the supporting part  23  contacting the base mount  210   a . Stated differently, the supporting part holds the part in the periphery of the hole  251  in the second surface opposite to the main surface  211  (the first surface) of the base mount  210   a.    
     Stated differently, the hole fixed part  20  (supporting part  23 ) of the lead wire  150  is capable of positioning the base mount  210   a  in the globe  110  when fixing the lead wire  150  to the base mount  210   a.    
     Note that, the number of the leads  21  included in the hole fixed part  20  is not limited to four, but may be three or larger than or equal to 5. 
     As illustrated in (a) in  FIG. 50  and (c) in  FIG. 50 , the part of the leads  21  of the hole fixed part  20 , projecting from the holes  251  are crimped (bent) such that the projecting part contact the main surface  211  of the base mount  210   a.    
     Stated differently, part of each of the four leads  21  is crimped from the second surface toward the main surface (the first surface) of the base mount  210   a  through the hole  251  and contacting the main surface  211  (the first surface) of the base mount  210   a . The hole fixed part  20  is fixed to the hole  251  by clipping the periphery of the hole  251  in the main surface  211  (the first surface) of the base mount  210   a  and the periphery of the hole  251  in the second surface of the base mount  210   a . Accordingly, the hole fixed part  20  is firmly fixed to the hole  251 . 
     Accordingly, the hole fixed part to be inserted into the hole  251  and fixed to the hole  251  is formed at the end of each of the lead wires  150 . 
     One lead  21  in the hole fixed part  20  fixed to the hole  251   a  is electrically connected to the wire bonding part  331  of the left-end semiconductor light-emitting device included in the group of light-emitting devices  300   a . One of the leads  21  in the hole fixed part  20  fixed to the hole  251   b  is electrically connected to the wire bonding part  332  of the right-end semiconductor light-emitting device in the group of light-emitting devices  300   a.    
     To put it differently, the lead wires  150   a  and  150   b  are electrically connected to the group of light-emitting devices  300   a  such that DC power from the lighting circuit  180  can be supplied to the group of light-emitting devices  300   a.    
     With the structure described above, the base mount  210   a  on which the semiconductor light-emitting devices  300  are mounted is supported by the lead wires  150   a  and  150   b  each having the hole fixed part  20  firmly fixed to the hole  251 . Accordingly, the base mount  210   a  can be firmly fixed by the lead wires  150   a  and  150   b . Accordingly, the base mount on which the semiconductor light-emitting device is mounted is fixed firmly. 
     In addition, the DC power can be supplied to the group of light-emitting devices  300   a  by using the lead wires  150   a  and  150   b.    
     Furthermore, the lead wire  150  supports the base mount  210   a  on which semiconductor light-emitting devices  300  are mounted. With this, it is possible to suppress a large part of the light emitted by the semiconductor light-emitting device  300  mounted on the base mount  210   a  being blocked. 
     Furthermore, the base mount  210   a  is translucent. With this, it is possible to prevent the large part of the light emitted by the semiconductor light-emitting device  300  from being blocked. Accordingly, a sufficient light distribution angle can be achieved. 
     Variation 1 of Embodiment 4 
       FIG. 51  is a cross-sectional view for describing the fixing structure according to the variation 1 of the embodiment 4. The fixing structure for the LED module  200 A shall be described in the variation 1 of the embodiment 4. 
     The variation 1 of the embodiment 4 is different from the structure in the Embodiment 4 illustrated in  FIG. 49  and  FIG. 50  in that the base mount  210   a  is fixed by a rod part  120   a  of the fixing part  120  as the stem as well. The rest of the structure for fixing the base mount  210   a  is identical to the embodiment 4. Accordingly, the detailed description is not repeated. 
     As described above, the fixing part  120  as the stem is provided on a side (the second surface) opposite to the main surface  211  of the base mount  210   a.    
     The shape of the fixing part  120  in the variation 1 of the embodiment 4 is described as the rod part  120   a  of the fixing part  120  extending to the vicinity of the surface opposite to the main surface  211  of the base mount  210   a.    
     The surface (the second surface) opposite to the main surface  211  of the base mount  210   a  is fixed to the tip of the rod part  120   a  of the fixing part  120  by adhesive  122 . The surface (the second surface) opposite to the main surface  211  of the base mount  210   a  is fixed to the tip of the rod part  120   a  of the fixing part  120 . Stated differently, the base mount  210   a  is also supported by the rod part  120   a.    
     According to the structure in the variation 1 of the embodiment 4, the base mount  210   a  is supported by the rod part  120   a  more firmly than the fixing structure according to the embodiment 4. Accordingly, the base mount  210   a  (the LED module  200 A) is fixed even more firmly than the fixing structure in the embodiment 4. 
     In addition, the shape of the fixing part  120  may allow the tip of the rod part  120   a  of the fixing part  120  contacts the surface opposite to the main surface  211  of the base mount  210   a . In this case, the adhesive  122  may not be necessary. 
     In the following description, a lightbulb-shaped lamp according to the variation 1 of the embodiment 4 may be referred to as a lightbulb-shaped lamp A 41 . 
     Variation 2 of Embodiment 4 
     The fixing structure for the LED module  200 A shall be described in the variation 2 of the embodiment 4. 
     In the variation 2 of the embodiment 4, the four LED modules  200 A are also referred to as an LED module  200 Aa,  200 Ab,  200 Ac, and  200 Ad in order to distinguish the four LED modules  200 A. The base mounts corresponding to the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad are also referred to as the base mount  210   aa ,  210   ab ,  210   ac , and  210   ad , respectively. 
       FIG. 52  is a cross-sectional view for describing the fixing structure according to the variation 2 of the embodiment 4. 
     (a) in  FIG. 52  illustrates the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad fixed. 
     (b) in  FIG. 52  is a cross-sectional view illustrating the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad fixed. More specifically, (b) in  FIG. 52  is a cross-sectional view of LED modules along the line A-A′ in (a) in  FIG. 52 . 
     In the following description, a lightbulb-shaped lamp according to the variation 2 of the embodiment 4 may be referred to as a lightbulb-shaped lamp A 42 . The lightbulb-shaped lamp A 42  is different from the lightbulb-shaped lamp  100 C according to the embodiment 4 illustrated in  FIG. 46  to  FIG. 49  and others in that the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad integrated by a connecting part  70  are included instead of the LED module  200 A, and fixing wires  152   a  and  152   b  are further included. The rest of the structure of the lightbulb-shaped lamp A 42  is identical to the lightbulb-shaped lamp  100 C. Accordingly, the detailed description is not repeated. 
     In this case, the lightbulb-shaped lamp A 42  includes the base mount  210   aa ,  210   ab ,  210   ac , and  210   ad  integrated by the connecting part  70 , as illustrated in (a) in  FIG. 52 . Stated differently, the lightbulb-shaped lamp A 42  has more than one base mount. Each of the base mount  210   aa ,  210   ab ,  210   ac , and  210   ad  is board-shaped. Each of the base mount  210   aa ,  210   ab ,  210   ac , and  210   ad  is not only board-shaped, but may be in a shape of quadrilateral prism. 
     The configurations of the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad are identical to the configuration of the LED module  200 A. Stated differently, a plurality of the semiconductor light-emitting devices  300  are mounted on the main surface  211  of each of the base mounts  210   aa ,  210   ab ,  210   ac , and  210   ad  corresponding to the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad, respectively. Accordingly, the group of light-emitting devices  300   a  is formed on the main surface  211  of each of the base mounts  210   aa ,  210   ab ,  210   ac , and  210   ad.    
     Furthermore, in the same manner as the base mount  210   a  in  FIG. 49 , the holes  251   a  and  251   b  are provided on ends of the base mount  210   a  in the longer direction of the base mounts  210   aa ,  210   ab ,  210   ac , and  210   ad . As described above, each of the holes  251   a  and  251   b  is a through hole passing through the base mount  210   a.    
     In the following description, each of the holes  251   a  and  251   b  is referred to as a first hole or a second hole, depending on the position of the hole in the corresponding base mount  210 . Stated differently, each of the base mounts has the first hole and the second hole passing through the base mount. 
     The hole fixed part  20  is firmly fixed to each of the holes  251   a  and  251   b  in the base mount  210   a  by using the fixing structure illustrated in  FIG. 50 . More specifically, the hole fixed part  20  is firmly fixed to each of the first hole and the second hole in the base mount  210 . 
     As illustrated in (a) in  FIG. 52 , the four bases  210   a  are arranged such that one end of each of the bases  210   a  is close to one ends of the other bases  210   a . Accordingly, the bases are arranged such that the one ends of the bases are close to one another. 
     In the following description, the hole  251  provided in one end of the base mount may be referred to as the second hole. 
     For example, in (b) in  FIG. 52 , the right end part of the base mount  210   aa  and the left end part of the base mount  210   ab  are close to each other. Stated differently, one ends of the base mounts close to one another include the right end part of the base mount  210   aa  and the left end part of the base mount  210   ab  in (b) in  FIG. 52 , for example. Accordingly, the hole  251   b  provided at the right end part of the base mount  210   aa  and the hole  251   a  provided at the left end part of the base mount  210   ab  are the second holes. Therefore, the second hole is provided at one ends of the base mounts close to one another. 
     Furthermore, in the following description, the hole  251  other than the second hole among the two holes  251  provided in the base mount is referred to as the first hole. For example, in (b) in  FIG. 52 , the hole  251   a  provided on the left end of the base mount  210   aa  and the hole  251   b  provided on the right end of the base mount  210   ab  are the first holes. 
     As illustrated in (a) in  FIG. 52  and (b) in  FIG. 52 , the connecting part  70  integrates the hole fixed part  20  fixed to the second holes in the bases  210   aa ,  210   ab ,  210   ac ,  210   ad . To put it differently, the four base mounts  210   a  are integrated by the connecting part  70  integrating the hole fixed parts  20  fixed to the second holes in the four base mounts  210   a.    
     The base mounts are integrated by the connecting part integrating the hole fixed parts fixed to the second holes in the base mounts. Accordingly, the LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad are integrated by the connecting part  70 . The integrated LED modules  200 Aa,  200 Ab,  200 Ac, and  200 Ad are light-emitting modules. 
     As illustrated in (a) in  FIG. 52 , the connecting part  70  is cross-shaped when viewed from the Z-axis direction. The connecting part  70  is composed of a conductive material. The conductive material is metal, for example. The metal is, for example, stainless, aluminum, or others. 
     As described above, the hole fixed part  20  is formed at the end of each of the lead wires  150   a  and  150   b . Stated differently, the hole fixed part  20  and the lead wire  150  are integrally formed. 
     Accordingly, the hole fixed part  20  to be fixed to the hole  251   a  provided at the left end part of the base mount  210   aa  is formed at the end of the lead wire  150   a . The hole fixed part  20  to be fixed to the hole  251   b  provided at the right end part of the base mount  210   ab  is formed at the end of the lead wire  150   b.    
     Stated differently, the hole fixed part  20  for a different hole provided on the base mounts integrated is formed at the end of each of the lead wires  150   a  and  150   b . Accordingly, the hole fixed part  20  to be fixed to the first hole provided in at least one base of the bases integrated is provided at the end of the lead wire  150 . 
     An end portion of the each of the fixing wires  152   a  and  152   b  is fixed by the fixing part  120 , in the same manner as the lead wires  150   a  and  150   b  in  FIG. 46 . Note that, the fixing wires  152   a  and  152   b  are metal wires not used for supplying power. 
     The shape of the fixing wires  152   a  and  152   b  is identical to the shape of the lead wire  150 . In the following description, each of the fixing wires  152   a  and  152   b  may be simply referred to as the fixing wire  152 . Stated differently, the hole fixed part  20  is formed at the end portion of each of the lead wire  152 . Stated differently, the hole fixed part  20  and the fixing wire  152  are integrally formed. 
     Accordingly, as illustrated in (a) in  FIG. 52 , the four base mounts integrated are supported by the lead wires  150   a  and  150   b  and the fixing wires  152   a  and  152   b  each having the hole fixed part  20 . Stated differently, the base mounts integrated are supported by at least two of the lead wires  150 . Stated differently, at least one of the base mounts integrated are supported by the lead wire  150 . 
     The group of light-emitting devices  300   a  formed on the base mount  210   aa , the group of light-emitting devices  300   a  formed on the base mount  210   ad , the group of light-emitting devices  300   a  formed on the base mount  210   ac , and the group of light-emitting device  300   a  formed on the base mount  210   ab  are electrically connected in series. 
     The lead wires  150   a  and  150   b  are electrically connected to the group of light-emitting devices  300   a  such that the DC power from the lighting circuit  180  can be supplied to the groups of light-emitting devices  300   a  corresponding to the base mount  210   aa ,  210   ab ,  210   ac , and  210   ad  through the hole fixed parts  20 . 
     With the structure described above, the base mounts  210   a  integrated are supported by the lead wire  150  and the fixing wire  152  each having the hole fixed part  20  at the end. The hole fixed part  20  is firmly fixed to the base mount. With this structure, it is possible to fix the base mounts  210   a  integrated may be fixed firmly. Accordingly, the base mounts integrated on which the semiconductor light-emitting device is mounted are fixed firmly. 
     In addition, the DC power can be supplied to the four groups of light-emitting devices  300   a  by using the lead wires  150   a  and  150   b  and the fixing wires  152   a  and  152   b.

     Since the base mount  210   d  is described with reference to  FIG. 45 , the detailed description is not repeated. The following is a simplified description. 
     As illustrated in  FIG. 53 , the holes  251   a ,  251   b ,  251   c , and  251   d  are provided at the four ends of the base mount  210   d.    
     In the following description, each of the holes  251   a ,  251   b ,  251   c , and  251   d  may be simply referred to as the hole  251 . 
     The holes  251  in  FIG. 53  have the same shape as the hole  251  illustrated in  FIG. 41  and others. The hole fixed part  20  is firmly fixed to each of the holes  251  in  FIG. 53 , as described with reference to  FIG. 50 . 
     The four groups of light-emitting devices  300   a  that are not illustrated are formed on the base mount  210   d . The four groups of light-emitting devices  300   a  are sealed by the four sealing parts  220 , respectively. 
     Note that, the four groups of light-emitting devices  300   a  formed on the base mount  210   d  are electrically connected in series such that the current flows through the current path PL 2 , for example. 
     The LED module  200 E is fixed by the lead wires  150   a  and  150   b , and the fixing wires  152   a  and  152   b.    
     Since the shape, structure, and function of the lead wires  150   a  and  150   b  and the fixing wires  152   a  and  152   b  are the same as described with reference to  FIG. 52 , the detailed description shall not be repeated. The hole fixed part  20  is formed at the end of each of the lead wires  150   a  and  150   b  and the fixing wires  152   a  and  152   b . Accordingly, the base mount  210   d  is supported by the lead wires  150   a  and  150   b , and the fixing wires  152   a  and  152   b.    
     With the structure described above, the cross-shaped base mount  210   d  is supported at the four parts by the lead wires  150  and the fixing wires  152  each having the hole fixed part  20  at the end. The hole fixed part  20  is firmly fixed to the base mount  210   d . With this structure, even if the base mount is cross-shaped, the LED module  200 E (the base mount  210   d ) can be fixed firmly. 
     Note that, the LED module  200 E may be fixed by the rod part  120   a  of the fixing part  120  at the center part on the back surface of the base mount  210   d , as illustrated in the fixing structure according to the variation 1 of the embodiment 4 ( FIG. 51 ). 
     Note that, the fixing wires  152   a  and  152   b  may be wires for supplying power to the group of light-emitting devices  300   a  in the same manner as the lead wires  150   a  and  150   b . In this case, the fixing wires  152   a  and  152   b  are electrically connected to the lighting circuit  180  such that the DC power from the lighting circuit  180  can be transmitted therethrough. In this case, the fixing wires  152   a  and  152   b  and the lead wires  150   a  and  150   b  are electrically connected to group of light-emitting devices  300   a  such that the power can be supplied to the group of light-emitting devices  300   a.
