The present invention relates to a lighting fixture, a light source component that can be attached to a mounting component of the lighting fixture, and a mounting component to which the light source component of the lighting fixture can be attached.
In recent years, LED (Light Emitting Diode) lamps have attracted attention as light sources to replace incandescent bulbs and fluorescent lamps, and their spread is increasing. For example, as a lighting fixture that replaces a lighting fixture for a fluorescent lamp, there is a lighting fixture for an LED lamp that includes a light emitting portion having substantially the same shape as a fluorescent lamp, a base disposed at an end of the light emitting portion, and a base pin protruding from the base. (For example, Non-Patent Document 1).
Non-Patent Document 1 describes an LED lamp formed in substantially the same shape as a straight tube fluorescent lamp (for example, a fluorescent lamp with a G13 base). This LED lamp employs a base compliant with the Japan Light Bulb Industry Association standard (JEL801: 2010), and base pins are arranged on both sides of the straight tube lamp. The base pin is composed of a power supply pin and a grounding pin, and is inserted into a socket to supply power to the LED lamp, and holds the LED lamp to prevent it from falling.
In such an LED lamp having substantially the same shape as a fluorescent lamp, it is necessary to dispose a structure such as a base and a socket, so that it is difficult to reduce the size and thickness of the lighting fixture. Therefore, LED lamps have been developed that employ a lamp shape or structure different from fluorescent lamps.
For example, Patent Document 1 describes a semi-cylindrical LED lamp formed in a shape different from that of a fluorescent lamp. This LED lamp has a power supply connector and a locking member on the back surface. The power supply connector is connected to a power supply cord extending from the luminaire main body and supplies power to the LED lamp. The locking member is made of a metal wire bent into a substantially rhombus shape, and is inserted into a locking hole formed in the lighting fixture main body and locked to the edge of the locking hole. A hook is formed in the locking hole, and the LED lamp is prevented from falling when the locking member is hooked on the hook. In this LED lamp, since the power supply connector and the locking member are arranged on the back surface, it is not necessary to provide a non-light emitting structure such as a base of a fluorescent lamp or a socket on the front surface of the lighting fixture. For this reason, the lighting fixture can be reduced in size and thickness.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.
FIG. 1 is a plan view, a front view, and a side view showing a lighting apparatus according to an embodiment of the present invention. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a side view. As shown in FIG. 1, the luminaire 1 according to the present embodiment includes an attachment component 2 and an LED module 3. The attachment component 2 is a component that is fixed to the ceiling or the like and to which the LED module 3 is attached. The attachment component 2 may be referred to by a name such as a lighting fixture body or a mounting fixture. The LED module 3 is a light source component that constitutes the light source of the luminaire 1 and is a component called by a name such as a light source module or a light source unit.
The attachment component 2 is formed in a rectangular shape with a bottom surface and a trapezoidal cross section, and the LED module 3 is disposed at the center thereof. The inclined surfaces arranged on both sides are reflectors formed by applying a white paint or the like. Hereinafter, the detailed structure of the attachment component 2 and the LED module 3 will be described with reference to cross-sectional views.
FIG. 2 is a cross-sectional view taken along line AA of the lighting apparatus illustrated in FIG. In the mounting component 2 shown in FIG. 2, an LED module mounting portion 21 for mounting the LED module 3 is formed.
The LED module mounting portion 21 has a concave structure in which the LED module 3 is fitted. For example, the concave structure is formed integrally with the reflection plate of the attachment component 2 by bending a plate-like member (for example, a sheet metal). A fixture fixture 27 is provided on the bottom side of the recess structure, and the power terminal block 26 and the LED module 3 are accommodated inside the recess structure.
The fixture fixture 27 is a member for attaching the fixture 2 to the installation location of the lighting fixture 1. The fixture 27 is, for example, a fastener (bolt and bolt) for fastening the structure and the attachment component 2 in a state where the base portion 29 is in contact with the structure at the installation location such as the ceiling 9 of the building. Nut etc.) (see FIG. 3). Here, the base portion 29 is a member that forms an installation surface that can be installed at the installation location.
The power terminal block 26 is a terminal block for supplying power to the LED module 3. Wiring extends from the power terminal block 26 and is connected to the LED module 3 via a connector 28 provided at the tip of the wiring (see FIG. 3).
The LED module 3 is a light source component including a light source, and is attached to the attachment component 2 to function as a lighting fixture. The LED module 3 includes an LED 35, a power supply circuit 36, a module cover 37, a stopper 38, a main body 31, and leaf springs 32A and 32B.
The LED 35 is, for example, a white LED or an LED of each color of red, blue, and green. In the LED module 3, a plurality of LEDs 35 are used and arranged uniformly on a rectangular substrate 351. The plurality of LEDs 35 are combined to function as, for example, a daylight color light source.
The power supply circuit 36 is a circuit that controls the voltage applied to the LED 35 and controls the lighting of the LED 35. The power supply circuit 36 controls the lighting of the plurality of LEDs 35, so that the LED module 3 can be dimmed and toned.
The power circuit 36 has a connector 34 that can be connected to a connector 28 connected to the power terminal block 26 (see FIG. 4). For example, wiring extends from the power supply circuit 36, a connector 34 is provided at the tip thereof, and the connector 34 is connected to a connector 28 connected to the power supply terminal block 26. The power circuit 36 receives power from the power terminal block 26.
The module cover 37 is a cover that covers the light source, and is also a member called a globe. The module cover 37 has a function of protecting the light source and diffusing light from the light source. For example, it is formed in a rectangular parallelepiped shape that is hollow and has an opening by a translucent resin material (for example, acrylic resin). A substrate 351 on which the LED 35 is mounted is disposed in the opening.
The stopper 38 is a member that can contact the edge of the LED module mounting portion 21 in a state where the LED module 3 is stored in the LED module mounting portion 21, and the LED module 3 is stored in the LED module mounting portion 21. Has a function to determine the position. The stopper 38 is, for example, a back surface portion of the module cover 37 formed so as to extend from the opening of the module cover 37 toward the outer periphery. The back surface of the module cover 37 protrudes from the opening of the module cover 37 toward the outside of the LED module mounting portion 21.
The main body 31 is a housing that supports the module cover 37 and the substrate 351 of the LED 35 and accommodates the power supply circuit 36. For example, the main body 31 is hollow and is formed in a rectangular parallelepiped shape having an opening. A power supply circuit 36 is housed inside, a substrate 351 is disposed so as to cover the opening, and the opening side functions as a front side (light source side). The side surface is connected to the end of the module cover 37. The main body 31 is mounted and accommodated in the LED module mounting portion 21 by leaf springs 32A and 32B.
The leaf springs 32 </ b> A and 32 </ b> B are connecting tools for attaching the LED module 3 to the attachment component 2. In a state where the main body rear surface 31A of the LED module 3 is directed to the mounting component 2, the leaf springs 32A and 32B are inserted into the insertion holes 22A and 22B of the mounting component 2, and the LED module 3 is interposed between the insertion holes 22A and 22B. Is attached. Below, insertion hole 22A, 22B of the attachment component 2 is demonstrated.
FIG. 3 is a perspective view showing an attachment component according to the embodiment. In the attachment component 2 shown in FIG. 3, insertion holes 22 </ b> A and 22 </ b> B are formed on the side surface of the concave structure of the LED module attachment portion 21. The insertion holes 22A and 22B penetrate the plate-like member that constitutes the LED module attachment portion 21, and these form a pair. The pair of insertion holes 22A and 22B face each other. The number of insertion holes 22A and 22B is the same as the number of leaf springs.
The insertion holes 22A and 22B have an opening in which an upper opening 221 and a lower opening 223 are continuous. For example, when two insertion holes 22A and 22B are formed, when the direction of the line connecting the two holes along the surface of the LED module mounting portion 21 is the vertical direction, the upper opening of the insertion hole 22A The insertion holes 22A, 22B are arranged such that the vertical distance between the upper opening 221 of the insertion hole 22B and the lower opening 223 of the insertion hole 22A is shorter than the vertical distance between the lower opening 223 of the insertion hole 22B. Are opposed to each other, and these openings are arranged in the vertical direction. The lower opening 223 and the upper opening 221 are continuous in the vertical direction. In other words, the lower opening 223 is arranged below the upper opening 221 (in the + Z direction in FIG. 3) and is arranged in contact with the sides.
The upper opening 221 is formed in a substantially rectangular shape having a long side with a predetermined width, and the leaf springs 32A and 32B can be inserted therein. For example, when the vertical direction is defined in the above direction, the long side is arranged in the horizontal direction, and the width of the long side is larger than the width of the distal end portion 321 of the leaf springs 32A and 32B, which will be described later. The width of the short side is larger than the thickness of the leaf springs 32A and 32B. The upper openings 221 of the insertion holes 22A and 22B are arranged parallel to the vertical direction. This is because it corresponds to the direction in which the leaf springs 32A and 32B can be elastically deformed (that is, the longitudinal direction), which will be described later.
The lower opening 223 is formed in a substantially rectangular shape, and is continuous with the upper opening 221 in the vertical direction with a width smaller than the width of the upper opening 221. For example, long sides are arranged in the horizontal direction, and the long sides are smaller than the width of the upper opening 221. Further, the width of the short side arranged in the vertical direction is larger than the thickness of the leaf springs 32 </ b> A and 32 </ b> B and larger than that of the upper opening 221.
In the lower opening 223, the distal end portions 321 of the leaf springs 32A and 32B, which will be described later, cannot be inserted, but the intermediate portion 323 can be fitted. For example, the insertion holes 22 </ b> A and 22 </ b> B are formed through the plate-like member constituting the LED module mounting portion 21, and as a result, a space having a width equal to or longer than the long side of the upper opening 221 is formed inside the lower opening 223. Is done. After inserting the tip portions 321 of the leaf springs 32A and 32B from the upper opening 221, the leaf springs 32A and 32B are moved from the upper opening 221 to the lower opening 223 inside the space, and the intermediate portion 323 is fitted into the lower opening 223. Is possible. Thereby, the front-end | tip part 321 can be latched to the lower opening 223, and the LED module 3 can be hold | maintained to insertion hole 22A, 22B via leaf | plate spring 32A, 32B. Hereinafter, the structure of the leaf springs 32A and 32B of the LED module 3 will be described with relation to the insertion holes 22A and 22B.
FIG. 4 is a perspective view showing the LED module according to the embodiment. In FIG. 4, the surface on the module cover 37 side where the LED 35 is disposed is the main body front surface 31B, and the opposite surface is the main body rear surface 31A. The LED module 3 shown in FIG. 4 is connected to the main body rear surface 31A of the main body 31, and has leaf springs 32A and 32B extending from the main body rear surface 31A toward the side (+ Y direction shown in FIG. 4). The two leaf springs 32A and 32B form a pair, and the pair of leaf springs 32A and 32B are arranged in opposite directions. The number of leaf springs 32A and 32B is the same as the number of insertion holes 22A and 22B.
The leaf springs 32A and 32B are elastic members that can be elastically deformed, elastically deformed in a state where stress is applied, and restored to the original shape by elastic force in a state where the stress is removed. For example, the end portions of the leaf springs 32A and 32B can be elastically deformed in the vertical direction from the state in which the end portions extend toward the side of the main body 31 to the state in which the end portions extend in the direction of the main body rear surface 31A. Further, the elastic state can be restored from the elastically deformed state to the original state, that is, a state where the end portion extends toward the side of the main body 31.
The plate springs 32A and 32B are, for example, a single plate-like member (metal plate, for example, stainless steel, spring steel) that is bent and integrated with the plate spring 32A, the support portion 33, and the plate spring 32B. A leaf spring is formed. The leaf springs 32 </ b> A and 32 </ b> B each have an intermediate part 323 and a tip part 321 extending from the intermediate part 323, and the intermediate part 323 is connected to the support part 33 fixed to the main body back surface 31 </ b> A of the main body 31. Each of the intermediate portion 323, the distal end portion 321, and the support portion 33 is disposed so that the plate-like surface faces the main body rear surface 31 </ b> A of the main body 31.
The intermediate part 323 is a belt-like structure and can be inserted into the upper opening 221 of the insertion holes 22A and 22B. The intermediate part 323 can be fitted into the lower opening 223 while the distal end part 321 enters the insertion holes 22A and 22B. It is. For example, the width of the intermediate portion 323 is smaller than either the long side of the upper opening 221 or the long side of the lower opening 223, and the thickness of the intermediate portion 323 is smaller than the short side of the upper opening 221. That is, the cross-sectional shape of the intermediate part 323 is smaller than that of the upper opening 221.
The intermediate portion 323 is bent from the support portion 33 in the order of the second bent portion 324 and the first bent portion 322. After being bent at the first bent portion 322, the intermediate portion 323 extends to and connects to the distal end portion 321.
The distal end portion 321 is formed in a substantially rectangular shape, and the long side is connected to the intermediate portion 323. The distal end portion 321 can be inserted into the upper opening 221 of the insertion holes 22A and 22B and cannot be inserted into the lower opening 223. Further, the distal end 321 can be locked to the lower opening 223 in a state where the distal end 321 enters the insertion holes 22 </ b> A and 22 </ b> B and the intermediate portion 323 is fitted in the lower opening 223. For example, the width of the long side of the tip 321 is smaller than the long side of the upper opening 221 and larger than the long side of the lower opening 223. The thickness of the tip 321 is smaller than the short side of the upper opening 221. That is, the cross-sectional shape of the distal end portion 321 is smaller than the upper opening 221 and larger than the lower opening 223.
The distance between the distal end portions 321, that is, the distance between the distal end portion 321 of the leaf spring 32 </ b> A and the distal end portion 321 of the leaf spring 32 </ b> B is a state in which the leaf springs 32 </ b> A and 32 </ b> B are not elastically deformed, that is, no stress is applied. It is larger than the distance between the insertion holes 22A and 22B. When the leaf springs 32A and 32B are inserted into the insertion holes 22A and 22B and the LED module 3 is attached to the mounting part 2, the above-mentioned distance is set by inserting a stress into the leaf springs 32A and 32B and elastically deforming the longitudinal direction. The distance is smaller than the distance between 22A and 22B.
The support portion 33 is a belt-like structure and can be fixed to the main body 31. Below, the attachment method of the support part 33 to the LED module 3 is demonstrated.
FIG. 5 is a cross-sectional view of the LED module and a perspective view showing an assembly method of the LED module. FIG. 5A is a cross-sectional view of the LED module, and FIG. 5B is a perspective view showing an assembly method of the LED module. A leaf spring 32A, 32B shown in FIG. 5A is formed with a groove insertion portion 333 that extends so as to branch from a connection portion between the support portion 33 and the intermediate portion 323 and is elastically deformable. The shape of the groove insertion portion 333 is a shape that can abut on a groove 317 described later. A mounting hole 331 is formed in the support portion 33.
On the other hand, grooves 317 are formed on both side surfaces of the casing of the main body 31. Further, a screw hole 315 is formed in the main body rear surface 31A of the casing of the main body 31 (see FIG. 5B).
As shown in FIG. 5B, first, a metal plate in which the leaf spring 32 </ b> A, the support portion 33, and the leaf spring 32 </ b> B are integrated is arranged so as to be parallel to the lateral direction of the main body 31. At this time, the main body 31 is disposed so as to be sandwiched between the groove insertion portions 333.
Next, the metal plate is pushed in from the main body rear surface 31 </ b> A side of the main body 31. As a result, the groove insertion portion 333 is elastically deformed once to sandwich the side surface of the main body 31 and is inserted into the groove 317 to restore the original shape.
Then, the position is adjusted so that the positions of the screw holes 315 on the main body 31 side and the mounting holes 331 on the support portion 33 side coincide. In this state, the bolt is inserted into the mounting hole 331 and fastened with the screw hole 315. Thus, the leaf springs 32A and 32B are attached to the LED module 3. The leaf springs 32A and 32B are used for assembling the lighting fixture 1. Below, the method to assemble the lighting fixture 1 using the attachment component 2 and the LED module 3 is demonstrated.
6 and 7 are diagrams showing a method of assembling the lighting fixture. As shown in FIG. 6A, first, the distal end portion 321 of the leaf spring 32 </ b> A is inserted into the insertion hole 22 </ b> A of the module attachment portion 21. The tip 321 is inserted from the upper opening 221 of the insertion hole 22A. Then, the distal end 321 is inserted into the insertion holes 22A and 22B, that is, into a space formed to have a size larger than the width of the long side of the upper opening 221, and the intermediate part 323 is moved from the upper opening 221 to the lower opening 223. Fit into the lower opening 223.
Next, the intermediate portion 323 is further advanced into the insertion hole 22A. The first bent portion 322 of the intermediate portion 323 is advanced until it reaches the lower opening 223, and the first bent portion 322 is hooked on the lower opening 223. In this state, it is possible to keep the state where the intermediate portion 323 is fitted into the lower opening 223 by the weight of the LED module 3. Further, since the width of the tip portion 321 located on the tip side of the intermediate portion 323 is larger than the width of the lower opening 223, the tip portion 321 can be locked to the lower opening 223 to prevent the LED module 3 from falling. Is possible. Since the 1st bending part 322 is hooked in the lower opening 223, the operator does not need to support the LED module 3 by hand from this state.
In this state, the wiring connector 28 extending from the attachment component 2 side and the wiring connector 34 extending from the LED module 3 are connected.
Next, as shown in FIG. 6B, the distal end portion 321 of the leaf spring 32 </ b> B is inserted into the insertion hole 22 </ b> B of the module attachment portion 21. The operation of inserting the leaf spring 32B into the insertion hole 22B is the same as that of the leaf spring 32A. When both the leaf springs 32A and 32B are inserted into both the insertion holes 22A and 22B, the leaf springs 32A and 32B are elastically deformed from a state extending toward the side of the main body 31 to a state extending toward the back surface of the main body 31. . For example, when the intermediate portion 323 of the leaf springs 32A and 32B is inserted into the insertion holes 22A and 22B up to a position exceeding the first bent portion 322, the connecting portion between the intermediate portion 323 and the support portion 33 is bent and elastically deformed. The angle formed by the intermediate portion 323 and the support portion 33 decreases from the angle P (see FIG. 6A) to the angle Q.
Next, as shown in FIG. 7C, the intermediate portion 323 of the leaf springs 32A and 32B is inserted into the insertion holes 22A and 22B up to the second bent portion 324. The leaf springs 32A and 32B are somewhat restored from the elastic deformation of FIG. Due to the elastic force, the bending of the connecting portion between the intermediate portion 323 and the support portion 33 is reduced, and the angle formed by the intermediate portion 323 and the support portion 33 is an angle R (angle R> angle Q). For this reason, the operator can push in the leaf springs 32A and 32B with a weaker force than the state of FIG.
Next, as shown in FIG. 7D, the leaf springs 32 </ b> A and 32 </ b> B are inserted to a position near the connecting portion between the intermediate portion 323 and the support portion 33 of the leaf springs 32 </ b> A and 32 </ b> B. The leaf springs 32A and 32B are further restored from the elastic deformation, and the bending of the connecting portion between the intermediate portion 323 and the support portion 33 is further reduced. In this state, the angle formed by the intermediate portion 323 and the support portion 33 is the angle S (angle S> angle R). As can be seen from a comparison with the state of FIG. 6A, this state is a state in which the leaf springs 32A and 32B are elastically deformed (angle P> angle S). For this reason, the LED module 3 is pulled to the back side by the elastic force of the leaf springs 32A and 32B. Then, when the stopper 38 of the module cover 37 abuts against the edge of the concave portion of the LED module mounting portion 21, the LED module 3 is arranged at a predetermined position. Thereby, the assembly of the lighting fixture 1 is completed.
As described above, in the lighting fixture 1 according to the present embodiment, the attachment parts 2 are provided with the insertion holes 22A and 22B, and the LED module 3 is provided with the leaf springs 32A and 32B. Further, the distance between both ends of the leaf springs 32A and 32B is larger than the distance between the insertion holes 22A and 22B, and the leaf springs 32A and 32B can be elastically deformed to reduce this distance by applying stress. It is. In such a structure, the LED module 3 can be attached to the attachment component 2 by the elastic force of the leaf springs 32A and 32B by inserting the leaf springs 32A and 32B elastically deformed into the insertion holes 22A and 22B. Thus, compared with the existing lighting fixture (for example, nonpatent literature 1), the lighting fixture 1 has a simple structure and few parts.
In addition, the insertion holes 22A and 22B of the attachment part 2 are formed in an opening in which the upper opening 221 and the lower opening 223 are continuous, and the inner side of the lower opening 223 is larger than the width of the long side of the upper opening 221. A space is formed. Further, the leaf springs 32 </ b> A and 32 </ b> B of the LED module 3 each have a tip portion 321 and an intermediate portion 323. As a result, when the leaf springs 32A and 32B are inserted into the insertion holes 22A and 22B and enter the inside, the distal end portion 321 can be locked to the lower opening 223. Therefore, in the lighting fixture 1, the LED module 3 is prevented from falling from the attachment component 2.
As mentioned above, although embodiment of this invention was described, various deformation | transformation are possible for the lighting fixture 1, the attachment component 2, and LED module 3 which concern on embodiment of this invention.
For example, in the above embodiment, the metal plate in which the leaf spring 32A, the support portion 33, and the leaf spring 32B are integrated is fixed to the main body 31 of the LED module 3 with bolts. However, the leaf springs 32A and 32B of the present invention are used. The fixing means is not limited to this. For example, a fitting hole is formed in the main body 31 of the LED module 3, and a fitting portion that can be fitted into the fitting hole and connected to the intermediate portion 323 is formed in the leaf springs 32A and 32B. The main body 31 and the intermediate part 323 may be fixed by being fitted into the fitting holes.
FIG. 8 is a sectional view showing a modification of the LED module and a perspective view showing an assembling method thereof. FIG. 8A is a cross-sectional view showing a modification of the LED module, and FIG. 8B is a perspective view showing an assembly method of the LED module. As shown in FIG. 8A, a single metal plate is bent to form an integrated leaf spring arranged in the order of leaf spring 32A, support portion 33, leaf spring 32B, and support portion 33. The fitting part 332 is formed in the upper part. The fitting portion 332 is formed by cutting a part of the support portion 33 and bending it into an L shape. An L-shaped corner portion of the fitting portion 332 protrudes from the surface of the support portion 33.
On the other hand, the main body 31 of the LED module 3 shown in FIG. 8B has a fitting hole 316 formed on the rear surface 31A of the main body. The fitting hole 316 has a substantially rectangular shape.
As shown in FIG. 8B, the fitting portion 332 formed in the support portion 33 is fitted into the fitting hole 316 of the main body 31, and the leaf springs 32 </ b> A and 32 </ b> B are fixed to the LED module 3. Since the fitting portion 332 is made of the same material as the leaf springs 32A and 32B, it can be elastically deformed. It is elastically deformed in the fitting hole 316 and can be fixed by its elastic force.
Moreover, although said embodiment demonstrated the case where two pairs of leaf | plate springs 32A and 32B were provided, the number of leaf | plate springs is arbitrary.
FIG. 9 is a perspective view showing another modification of the LED module. FIG. 9A and FIG. 9B show other modified examples of different LED modules. As shown in FIG. 9A, the LED module 3 may be provided with a pair of leaf springs 32A and 32B, for example. Also in such a form, when the LED module 3 is substantially rectangular parallelepiped shape, that is, when the module cover 37 side is substantially rectangular, a form in which the pair of leaf springs 32A and 32B extend in the short direction is preferable. In existing luminaires (for example, fluorescent lamps), a plurality of lamps are often arranged in the longitudinal direction. Therefore, when the pair of leaf springs 32A and 32B extend in the short direction, the luminaires 1 are mutually connected. Hard to interfere.
In the above-described embodiment, the pair of leaf springs 32A and 32B is configured by an integral plate member, and the pair of leaf springs 32A and 32B is integral with the support portion 33. It does not matter whether the leaf springs 32A and 32B are integral or separate members. For example, as illustrated in FIG. 9B, the plate springs 32 </ b> A and 32 </ b> B may be configured by separate plate-like members connected to separate support portions 33.
Further, the pair of leaf springs 32A and 32B may not be arranged substantially in a straight line via the support portion 33. For example, as shown in FIG. 9B, the leaf springs 32A and the leaf springs 32B are alternately arranged. May be. It suffices if the leaf springs 32A and 32B are respectively disposed on one side surface of the LED module 3 and the other side surface opposite to (or opposed to) the side surface, and it does not matter at which position on the side surface.
In the above-described embodiment, the form in which the pair of leaf springs 32A and 32B has the tip portion 321 and the intermediate portion 323 having the same size has been described. However, the leaf springs 32A and 32B have different sizes. It may be a shape. For example, as shown in FIG. 9B, the tip portion 321 of the leaf spring 32A may be wider than the tip portion 321 of the leaf spring 32B. In this case, the insertion holes 22A and 22B corresponding to the leaf springs 32A and 32B are also formed in different sizes and shapes.
In the above-described embodiment, the mode in which the back portion of the module cover 37 forms the stopper 38 has been described. However, the shape of the stopper 38 of the present invention is not limited to this. For example, like the LED module 3 shown in FIG. 9 (A) and FIG. 9 (B), a stopper 38 protruding toward the side may be used. Specifically, the stopper 38 may be a plate-like member that protrudes from the side surface of the main body 31 in a direction substantially perpendicular to the side surface and that is substantially parallel to the main body back surface 31A. The stopper 38 only needs to be able to contact the edge of the concave portion of the LED module mounting portion 21 when the leaf springs 32A and 32B are inserted into the insertion holes 22A and 22B to be elastically deformed and restored from the state. It does not matter which member the stopper 38 is part of. For example, it does not matter whether the stopper 38 is integral with the module cover 37 or the main body 31 or is a separate structure. In the present invention, the stopper 38 has an arbitrary configuration.
In the above embodiment, the module cover 37 has a rectangular parallelepiped shape, but the shape of the module cover 37 is not limited thereto. For example, in order to make it easy to grasp the module cover 37, an uneven portion may be formed on the surface.
FIG. 10 is a cross-sectional view showing a modification of the module cover in the LED module. The module cover 37 shown in FIG. 10A has a non-slip portion 391 having a semicircular cross section and a concave shape on the side surface. The module cover 37 shown in FIG. 10B is provided with a non-slip portion 392 having a Z-shaped cross section and an uneven shape on the side surface. If it is such a form, when removing the LED module 3 from the attachment component 2, it is possible to grasp the module cover 37 easily.
In the above embodiment, the tip portions 321 of the leaf springs 32A and 32B and the upper openings 221 and the lower openings 223 of the insertion holes 22A and 22B are formed in a substantially rectangular shape, but these shapes are substantially omitted. It is not limited to a rectangle.
FIG. 11 is a perspective view showing a modification of the leaf spring and the insertion hole of the LED module. 11A and 11C show a modification of the leaf spring, and FIGS. 11B and 11D show a modification of the insertion hole. In the leaf spring 32A shown in FIG. 11A, the tip portion 321 has a hexagonal shape. On the other hand, in the insertion hole 22A shown in FIG. 11B, the upper opening 221 has a quadrangular shape and the lower opening 223 has an oval shape.
Further, in the leaf spring 32A shown in FIG. 11C, the tip portion 321 has an oval shape. On the other hand, in the insertion hole 22A shown in FIG. 11D, the upper opening 221 has an oval shape and the lower opening 223 has a rectangular shape.
As described above, the distal ends 321 of the leaf springs 32A and 32B and the upper opening 221 and the lower opening 223 of the insertion holes 22A and 22B are not limited to a substantially rectangular shape or an oval shape. For example, as shown in FIGS. 11A and 11B, the widest portions (for example, the long axis portions) of the upper opening 221 and the lower opening 223 of the insertion hole 22A are W11 and W22, respectively. When the portion where the lower opening 223 is in contact with the opening 221 is W21 and the widths of the tip portion 321 and the intermediate portion 323 are W1 and W2, respectively, W11> W1> W21> W2 is satisfied and W1> W22> W2 is satisfied That's fine. The shape of the leaf springs 32A and 32B and the insertion holes 22A and 22B is not particularly limited as long as such a relationship is satisfied.
In the above embodiment, the upper opening 221 and the lower opening 223 of the insertion hole 22A and the upper opening 221 and the lower opening 223 of the insertion hole 22B have been described as being arranged in a substantially straight line. It suffices if they are arranged in the vertical direction, and do not have to be arranged substantially in a straight line.
FIG. 12 is a perspective view showing a modified example of the attachment component. 12 (A) and 12 (B) show modifications of different mounting parts. As shown in FIG. 12A, for example, the insertion holes 22A and the insertion holes 22B are alternately arranged. Thus, the insertion holes 22A and 22B may be arranged obliquely in the vertical direction. The insertion holes 22 </ b> A and 22 </ b> B only need to have a vertical distance between the upper openings 221 of the insertion holes 22 </ b> A and 22 </ b> B shorter than a vertical distance between the lower openings 223. In this case, if the insertion holes 22A and 22B are assumed to be in the respective vertical directions in the direction in which the lines connecting the upper openings 221 or the lower openings 223 are oriented, the respective vertical directions are arranged in parallel. Good.
Moreover, although said embodiment demonstrated the form in which insertion hole 22A, 22B was formed inside the recessed part of LED module attaching part 21, LED module attaching part 21 is not restricted to a recessed part shape. For example, as shown in FIG. 12 (B), the LED module mounting portion 21 may be formed to have a horizontal surface with the installation surface (for example, the ceiling), and insertion holes 22A and 22B may be formed on the surface. Also in this case, as described above, in the insertion holes 22A and 22B, the vertical distance between the upper openings 221 of the insertion holes 22A and 22B is shorter than the vertical distance between the lower openings 223, and the upper opening 221. Assuming that the direction in which the lines connecting the two or the lower openings 223 face is the respective vertical directions, the respective vertical directions may be arranged in parallel. Moreover, the LED module attachment part 21 may be formed in a convex shape, and the insertion holes 22A and 22B may be formed in the convex surface. Thus, in the present invention, the shape of the LED module mounting portion 21 may be a flat surface or a convex surface.
In the above embodiment, the form using the leaf springs 32A and 32B has been described. For example, the elastic deformation from the state extending toward the main body 31 of the LED module 3 toward the back direction of the main body 31 is performed. It can be replaced with possible elastic members. Further, the leaf spring may be, for example, a thin leaf spring, a stacked leaf spring, a flat spring, or the like.
In the above embodiment, the insertion holes 22A and 22B have been described as penetrating through the plate-like member constituting the LED module attachment portion 21. However, in the present invention, the insertion holes 22A and 22B serve as the LED module attachment portion 21. It does not restrict to the form which penetrates. For example, the insertion holes 22 </ b> A and 22 </ b> B have an opening in which the upper opening 221 and the lower opening 223 are continuous in the vertical direction, and a space having the same width as the width of the upper opening 221 is formed inside the lower opening 223. There may be. A space having a lateral width equal to or larger than the lateral width of the upper opening 221 may be formed inside the lower opening 223.
