Abstract:
[Problem] To provide an illumination system with which a visual effect is provided such that it is possible to give an appearance of expanding depth on the far side of a wall face, even if a person stands directly in front thereof. 
     [Solution] An illumination system ( 100 ) comprises a light source ( 130 ), and a reflection board ( 120 ) that provides a reflection face that reflects illumination light from the light source ( 130 ). The reflection lace of the reflection board ( 120 ) is a processed reflection face in which are disposed a plurality of grooves which are very narrow parallel straight lines or parallel curved lines with respect to a flat plane. A support body ( 110 ) supports the light source ( 130 ) facing and in close proximity to the processed reflection board of the reflection board ( 120 ). Light points appear, arranged perpendicularly in the center of the reflection board ( 120 ) facing the light source. The formation locations of virtual images of each of the light points are formed further in the depth direction from the processed reflection board the further apart they are vertically, and thus a viewer has the sense of viewing a light beam track which is formed when a horizontal plane, which seemingly expands horizontally in the depth of the wall face, is illuminated, and has the sense of viewing an expanding space in the depth direction of the wall face.

In addition, the present invention relates to a display object employing the illumination system of the present invention which can highlight the displayed merchandize by the visual effect of the light beam track of irradiation light and reflection light provided by the illumination system of the present invention. 
       BACKGROUND ART 
       [0003]    Various types of illumination system are developed. The illumination system of the present invention is not limited to the one as a merchandize display fixture, but as an example object, the conventional illumination system as applied as a merchandize display fixture is described below. 
         [0004]    For example, the illumination system shown in JP2006-346238 (prior art 1) comprises a longitudinal illumination such as a fluorescent lamp installed in front of a shelf board of a merchandize display fixture, and a sectionally U-shaped translucent illumination cover installed to cover the front of the longitudinal illumination and the shelf board of a merchandize display fixture.

       DISCLOSURE OF THE INVENTION 
     The Problems to be Solved 
       [0010]    Display for promotion applying the artificial illumination effect is increasing in importance in various spaces such as a store, an office and a private room in the house. 
         [0011]    The above mentioned conventional illumination system provides the illumination effect for emphasizing the merchandize arrayed in the merchandize display shelf. The illumination effect focuses on highlighting the merchandize for brightening and shining the merchandize itself. 
         [0012]    However, the required illumination system for the store, the office and the private room in the house is not only the illumination system applying the illumination effect for highlighting the merchandize for brightening and shining the merchandize itself, but also the illumination system applying the illumination effect for arousing aesthetic pleasure by the illumination and obtaining the visually decorated emotional effect at the surroundings of the merchandize. In other word, not only the illumination effect by the direct illumination focusing on the merchandize, but also the illumination effect by the indirect illumination around of the merchandize is becoming important, which gives people a sense of calm. 
         [0013]    The space around the wall in the store, the office and the private room in the house is important. If the space around the wall is utilized effectively, the value of the room space increases. Especially, the wall partitions space and could be considered as a physical obstruction, so it is important for wall to enhance space around the wall for giving the customer the feeling of an extended space spread toward the opposite side of the wall. In general, a mirror is utilized for this effect. By installing the mirror to the wall, the image of the room space can be seen in the mirror, and the people standing in front of the mirror do not recognize the wall to partition the room space and feel as if the extended space is spread toward the opposite side of the wall instead. 
         [0014]    However, if the mirror installed to the wall, the people standing in front of the mirror actually can recognize the mirror by watching themselves. In addition, the mirror can just reflect the image of the room space, so the mirror cannot provide the illumination effect which gives people an aesthetic sensation. Sometimes, the mirror may make the people anxious and cause an uncomfortable feeling. 
         [0015]    The value of the illumination system is large, when the visual effect can provide people standing in front of the wall with the feeling that the extended space is spread opposite side of the wall, instead of recognizing the mirror reflecting the image of the room space. 
         [0016]    It is an object of the present invention to provide an illumination system which visual effect can provide people standing in front of the wall with the feeling that the extended space is spread toward the opposite side of the wall, instead of recognizing the mirror reflecting the image of the room space, and provide the illumination effect for arousing a beautiful feeling by the illumination and obtaining the visually decorated emotional effect at the around of the object. 
       Means for Solving the Problems 
       [0017]    In order to solve the problem shown above, the present invention comprises the following configuration. The components described below can be employed in an arbitrary combination as desired. The technical feature and embodiment of the present invention is not limited to the description below. It should be understood that various changes are possible based on the whole specification and drawings or the recognition of the ordinary skilled person in the technical field of the invention. 
         [0018]    In order to achieve the above-mentioned object, the present invention of an illumination system comprises; a light source; a reflection board for providing a reflection plane for reflecting light emitted by the light source; wherein the reflection plane of the reflection board is a processed reflection plane inscribed with numerous fine straight grooves arranged approximately in parallel or arranged in a curve approximately parallel to each other, providing an illumination effect with reflected light from the numerous fine grooves arranged approximately in parallel or arranged in a curve approximately parallel to each other generated by emitting light from the light source to the processed reflection plane of the reflection board. 
         [0019]    According to the above-mentioned configuration of the illumination system, an extremely large number of positional light sources is generated on the processed reflection plane because there is a lot of fine straight grooves arranged approximately in parallel or arranged in a curve approximately parallel to each other are inscribed to the processed reflection plane, with each edge of the grooves and ribs becoming an extremely small positional light source. In addition, the reflected light on the processed reflection plane shows a pattern in which light intensity becomes weakened geometrically corresponding to the emitted light angle, and there is not a high reflection ratio as a whole compared with that of mirror. Therefore, the reflected light pattern is generated by the superimposing of each extremely small positional light source, the processed reflection plane does not create glare of the object facing the processed reflection plane, and the reflection pattern along to the groove direction is hardly created. As a result, the reflection pattern on the processed reflection plane becomes a linear pattern crossing the groove direction, located in the center position facing to each light source. This linear pattern of the reflection pattern can be seen as the light track generated on the extended horizontal plane spread opposite side of the wall, so the people standing in front of the illumination system feels and recognize the extended horizontal plane to be spread toward the opposite side of the wall. 
         [0020]    In the above mentioned configuration, a groove pattern on the processed reflection plane is formed by a lot of fine straight grooves arranged approximately in parallel. Another groove pattern on the processed reflection plane is formed by a lot of fine grooves arranged in curve approximately parallel to each other. 
         [0021]    Either groove pattern on the processed reflection plane can provide the visual effect by the reflection pattern for the people standing in front of the illumination system the feeling and recognition of the light track being seen on the extended horizontal plane spread toward the opposite side of the wall. 
         [0022]    Next, in the above mentioned configuration, the light source may be a plurality of positional light sources, or may be a single or a plurality of linear light source. The reflection pattern on the processed reflection plane becomes different depending on the number of the light source and the type of the light source (such as a positional light source and a linear light source), and the visual effect can be varied. 
         [0023]    Next, there are a variety of patterns of the position where the light source is installed. 
         [0024]    For example, the light source can be installed to roof or wall nearby the processed reflection plane of the reflection board. 
         [0025]    In another configuration, the illumination system includes a light source support body for supporting the light source, and the light source is supported by the light source support body facing and being close to the processed reflection plane of the reflection board. For example, the light source support body is a structure including a shelf-shaped frame arranged in front of the reflection board apart from a certain gap, and the light source supporting position is located in a plane of the shelf-shaped frame facing the processed reflection plane of the reflection board. 
         [0026]    Next, there are a variety of patterns of the angle of the light emitting axis of the light source. 
         [0027]    For example, the emitting axis of the light source is supported in the direction of a right angle crossing the processed reflection plane of the reflection board. 
         [0028]    In other configuration, the emitting axis of the light source is supported in a predetermined angle crossing the processed reflection plane of the reflection board. 
         [0029]    The reflection pattern on the processed reflection plane can be varied according to the emitting axis of the light source. The visual effect can be varied for the people standing in front of the illumination system to feel and recognize as if the extended horizontal plane is spread toward the opposite side of the wall comparatively greatly or comparatively smally according to the variation of the length and the angle of the light track extended on the horizontal plane spread toward the opposite side of the wall. 
         [0030]    It is possible for the illumination system of the present invention to provide an illumination effect with a time variation by controlling the switching of the light source on and off or controlling the switching of the selected lighting light source. 
         [0031]    In other configuration, a multicolor light source can be employed as the light source. The illumination system of the present invention can provide the illumination effect having a color variation by controlling the switching the selected color in the light source. 
         [0032]    The illumination system of the present invention can applied to various objects. 
         [0033]    For example, the illumination system of the present invention can be applied to a wall of a construction decoration object. 
         [0034]    For example, the illumination system of the present invention can be applied to a roof of a construction decoration object. 
         [0035]    For example, the illumination system of the present invention can be applied to a store decoration object. 
         [0036]    For example, the illumination system of the present invention can be applied to a merchandize display object. 
         [0037]    For example, the illumination system of the present invention can be applied to furniture. 
         [0038]    For example, the illumination system of the present invention can be applied to a signboard. 
       Effect of the Invention 
       [0039]    According to the present invention of the illumination system, there is a lot of fine straight grooves arranged approximately in parallel or arranged in a curve approximately parallel to each other inscribed on the processed reflection plane, so the reflection pattern on the processed reflection plane can be seen as the light track generated on the extended horizontal plane spread toward the opposite side of the wall, so the people standing in front of the illumination system feel and recognize the extended horizontal plane to spread toward the opposite side of the wall. The processed reflection plane does not create glare of the object facing the processed reflection plane, so the people standing in front of the illumination system feel and recognize the extended horizontal plane to spread toward the opposite side of the wall. 
     
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0040]    Some embodiments of an illumination system according to the present invention are described below with reference to the relevant drawings. Needless to add, the claims of the present invention include but are not limited to the application, configuration, or quantity shown in the following embodiments. 
       Embodiment 1 
       [0041]    First of all, the principle of the particular visual effect obtained by the illumination system is described briefly. 
         [0042]    The illumination system  100  includes the reflection board  120  and the light source  130 . 
         [0043]    The light source  130  is a device for emitting the light. The principle of light emission is not limited. For example, a LED, a light bulb, a display device such as EL panel and LCR panel can be applicable as long as the device can provide light. There is an electric supply apparatus to provide electricity to the light source  130  (not illustrated in drawings). 
         [0044]    There are a lot of variations for the type and the number of the light source according to the configuration of the illumination system  100 . For example, the light source may be a plurality of positional light sources, may be the single linear light source or may be a plurality of linear light sources. 
         [0045]    Regarding the emitting axis of the light source  130 , it may be at a right angle relative to the processed reflection plane of the reflection board  120  or may be a predetermined certain angle relative to the processed reflection plane of the reflection board  120 . 
         [0046]    The reflection board  120  is a component for providing the processed reflection plane for reflecting the emitted light from the light source  130 . 
         [0047]    The feature of the reflection board  120  is that the processed reflection plane is inscribed a lot of fine grooves arranged approximately straight in parallel or arranged in a curve approximately parallel to each other. For example, a lot of fine grooves are inscribed in the smoothly finished metal surface in the same direction using a turning process with lathe. The processing material bundling a lot of fine wires may be used for inscribing fine grooves. Such processing may be called hair-line processing. The hair-line processing is a processing for scratching a lot of fine grooves on a metal surface in the same direction. 
         [0048]    The illumination system  100  provides an illumination effect by emitting light from the light source to the processed reflection plane of the reflection board and reflecting the emitted light with a lot of fine grooves arranged approximately straight in parallel or arranged in a curve approximately parallel to each other. 
         [0049]    The principle of the particular visual effect obtained by the illumination system is described briefly. 
         [0050]      FIG. 1  is an enlarged schematic view showing a part of the processed reflection plane. As shown in  FIG. 1 , there are a fine groove  122  and a rib  121  between grooves  122 . 
         [0051]    The actual processed reflection plane has a lot of fine grooves  122  arranged approximately straight in parallel or arranged in a curve approximately parallel to each other. The illustrated processed reflection plane shown in  FIG. 1  has grooves  122  arranged in approximately the horizontal direction. 
         [0052]    If the grooves  122  are not arranged in the same direction precisely in micro view, it is enough for the grooves  122  to be arranged in approximately in the same direction. 
         [0053]    If the reflection plane is just a mirror, the reflection plane has a high reflection ratio because the mirror has very smooth finished plane everywhere even in micro view. Therefore, the reflection angle is geometrically decided corresponding to the incidence angle, so the reflection light is uniquely obtained from the emitted light one by one. As a result, the reflection image is clearly seen as the mirror image. 
         [0054]    In contrast, if the reflection plane is the processed reflection plane having a lot of fine grooves  122  arranged approximately straight in parallel or arranged in a curve approximately parallel to each other as shown in  FIG. 1  there is a low reflection ratio, lower than that of mirror, and the emitted light may reflect and diffuse on ribs  121  and grooves  122 . The ribs  121  and the grooves  122  are arrayed approximately in parallel in macro, so the reflecting portion acts like the positional light source and light spots appear. 
         [0055]    The light spots of the positional light source are not spread uniformly but are located in the center line crossing the ribs  121  and grooves  122  because the ribs  121  and the grooves  122  are inscribed in horizontal in macro view. Horizontally, the ribs  121  may reflect the incident light symmetry direction, and the grooves  122  may absorb the incident light, so a light spot appears at the center line where the light source faces and no other light spots appear horizontally. 
         [0056]      FIG. 2  is a macro schematic view showing a behavior of the light reflecting on the horizontal axis. As shown in  FIG. 2 , the ribs  121  may reflect the incident light symmetry direction, the grooves  122  may absorb the incident light, so the attenuation is large in horizontal axis, so one light spot appears at the center and other light spots does not appear on horizontal axis. 
         [0057]    The emitted light from the light source  130  to the reflection board  120  spreads in various directions, not only the horizontal direction but also the vertical direction.  FIG. 3  is a macro schematic view showing a behavior of the light reflecting on the vertical axis in the center part of the reflection board facing to the light source  130 . As shown in  FIG. 3  ( a ), light is emitted from the light source  130 , then as shown in  FIG. 3  ( b ), light is reflected on the vertical axis. By this reflected light, a light spot appears in the center part. Therefore, as shown in  FIG. 3  ( c ), light spots appear along the vertical axis. However, the distance from the reflection plane of the position where the virtual image of each light spot forms depends on the vertical distance, so the people standing in front of the illumination system feel and recognize there to be an extended horizontal plane spread toward the opposite side of the wall, and the light track is recognized as the light track of the head light beam projecting on the extended horizontal plane. 
         [0058]    Each of  FIG. 4  to  FIG. 6  is a schematic view showing the above described phenomenon in detail. 
         [0059]      FIG. 4  is a schematic view showing the light behavior when the reflection plane of the reflection board  120  is a mirror and how the virtual image is seen. 
         [0060]    As shown in  FIG. 4 , a LED as a light source  130  is present facing and close to the mirror, and the watcher sees from behind the light source  130 . In  FIG. 4 , four light tracks are drawn as samples of the light emitted from the LED as the light source  130 . 
         [0061]    The emission light ( 1 ) is light emitted toward the upper direction. The reflection light ( 1 ) reflecting on the mirror turns upward corresponding to the incidence angle. The watcher does not see the reflection light ( 1 ). 
         [0062]    The emission light ( 2 ) is light emitted toward the upper direction but lower than the emission light ( 1 ). The reflection light ( 2 ) reflecting on the mirror turns up corresponding to the incidence angle, and the reflection light ( 2 ) just goes to the watcher&#39;s eye. The watcher can watch the virtual image. The position where the virtual image forms is the symmetry folded position of the emission light ( 2 ) on the mirror surface. 
         [0063]    The emission light ( 3 ) is light emitted toward the lower direction. The reflection light ( 3 ) reflecting on the mirror turns downward corresponding to the incidence angle. The watcher does not see the reflection light ( 3 ). 
         [0064]    The emission light ( 4 ) is light emitted toward the lower direction. The reflection light ( 4 ) reflecting on the mirror turns downward corresponding to the incidence angle. The watcher does not see the reflection light ( 4 ). 
         [0065]    As shown above, when the reflection plane is a mirror, the watcher can see one virtual image clearly. 
         [0066]    Next,  FIG. 5  is a schematic view showing the light behavior when the reflection plane of the reflection board  120  is the processed reflection plane and how the virtual image is watched. 
         [0067]    As shown in  FIG. 5 , a LED as a light source  130  is present facing and close to the processed reflection plane, and the watcher sees from behind the light source  130 . In  FIG. 5 , the same as  FIG. 4 , four light tracks are drawn as samples of the light emitted from the LED as the light source  130 . 
         [0068]    The emission light ( 1 ) is light emitted toward the upper direction. A part of the reflection light ( 1 ) goes to the watcher&#39;s eye because the light spot appears on the processed reflection plane. The watcher can see the virtual image. It is recognized that the position where the virtual image forms is the symmetry folded position of the emission light ( 1 ) whose distance is the same as that of the emission light ( 1 ) traveling to the processed reflection plane. 
         [0069]    The emission light ( 2 ) is light emitted toward the upper direction. A part of the reflection light ( 2 ) goes to the watcher&#39;s eye because the light spot appears on the processed reflection plane. The watcher can see the virtual image. It is recognized that the position where the virtual image forms is the symmetry folded position of the emission light ( 2 ) whose distance is the same as that of the emission light ( 2 ) traveling to the processed reflection plane. 
         [0070]    Both of the emission light ( 3 ) and the emission light ( 4 ) are light emitted toward the lower direction. The same as the emission light ( 1 ) and the emission light ( 2 ), a part of the reflection light ( 3 ) and the reflection light ( 4 ) also go to the watcher&#39;s eye because the light spot appears on the processed reflection plane. The watcher can see the virtual image. It is recognized that the position where the virtual image forms is the symmetry folded position of the emission light ( 3 ) and the emission light ( 4 ) whose distances are the same as that of the emission light ( 3 ) and the emission light ( 4 ) traveling to the processed reflection plane respectively. 
         [0071]    As shown in  FIG. 5 , when the reflection plane is the processed reflection plane, the watcher can see the virtual image of a LED as a light source  130  present facing and close to the processed reflection plane, when the watcher watches from behind the light source  130 . In  FIG. 5 , the same as  FIG. 4 , four light tracks are drawn as samples of the light emitted from the LED as the light source  130 . 
         [0072]    As shown above, when the reflection plane is a mirror, the watcher can see the series of plural positional light in vertical on the processed reflection plane according to the distance and the angle. 
         [0073]      FIG. 6  is a schematic view showing the series of the virtual images and the series of the light tracks formed by a series of the emission light emitted by a LED as the light source  130 . As shown in  FIG. 6 , numerous virtual images are arrayed vertically. These are recognized as the lower the virtual image is formed, the larger the distance between the virtual image and the processed reflection plane. In result, the light track formed by overlapping of the numerous virtual images can be seen as if there is an extended horizontal plane spread toward the opposite side of the wall, and the light tracks are recognized as the light track of the head light beam projecting on the extended horizontal plane. 
         [0074]    In the above description, the angle of the emitting axis of the light source  130  is a right angle relative to the processed reflection plane of the reflection board  120 . The emitting axis of the light source  130  may be supported at a predetermined angle relative to the processed reflection plane of the reflection board  120 . If the angle of the emitting axis of the light source  130  is varied, the strength and the position of the light tracks formed by merging the virtual images are varied. 
         [0075]    In the above description, numerous fine grooves inscribed to the processed reflection plane of the reflection board  120  are arranged approximately straight in parallel. Numerous fine grooves may be arranged in a curve approximately parallel to each other. If numerous fine grooves are arranged in a curve approximately parallel to each other, the strength and the position of the light tracks formed by merging the virtual images are also varied. 
         [0076]    As shown above, the strength and the position of the light tracks formed by merging the virtual images can be varied corresponding to the status of the inscription numerous fine groove, the position of the light source  130  supported by the light source support body  110 , and the angle of the emission axis of the light source  130 . 
         [0077]    Various materials can be employed as the material of the reflection board  120 . For example, metal such as stainless steel, aluminum and brass; glass; plastic board such as acrylic resin board; and wood can be employed. According to the difference of the material, the color and impression of the light tracks may vary, and a variety of visual effects may be obtained. 
         [0078]    By the above described principle, the particular visual effect can be obtained by the illumination system  100 . In addition to the visual effect, the illumination system  100  of the present invention can provide a decoration effect that works on the object put on the shelf-shaped frame. The illumination effect of the illumination system  100  of the present invention is not the direct illumination focusing on the shining the merchandize, but the indirect illumination around the merchandize whose visual effect provides the calm space including the merchandize for attracting people. 
         [0079]    As shown above, the illumination system  100  comprises a light source  130  and a reflection board  120  providing the processed reflection plane in which numerous fine grooves are inscribed to the surface arranged approximately straight in parallel or arranged in a curve approximately parallel to each other, and the illumination system  100  can obtain the illumination effect provided by the reflection on numerous fine grooves arranged approximately straight in parallel or arranged in a curve approximately parallel to each other. 
         [0080]    When the emission light from the light source  130  is projected on the reflection board  120 , the reflection light pattern can be seen as the light track of the headlight beam projecting on the extended horizontal plane as if there is an extended horizontal plane spread toward the opposite side of the wall. There is no glare of the object facing to the processed reflection plane, so the visual effect is achieved whereby the watcher can recognize that there is an extended horizontal plane spread toward the opposite side of the wall. 
         [0081]    The basic principle of the visual effect is the same even if the type and the number of the light source  130  vary. Therefore, there are many variations of the illumination system  100 . The light source  130  may be a plurality of positional light sources, may be the single linear light source or may be a plurality of linear light sources. The angle of the emission axis of the light source  130  may be a right angle relative to the processed reflection plane of the reflection board  120  or may be a predetermined angle relative to the processed reflection plane of the reflection board  120 . 
         [0082]    The illumination effect may include time variation by controlling the switching of the light source on and off or the controlling the switching of the selection of the light among a plurality of the light sources  130 . For example, the light selection may be switched one by one among the plurality of the light sources  130 , and the visual effect is that the light track may move time by time. 
         [0083]    The illumination effect may include color variation by switching the selected color in the light source  130  if multicolor light sources are employed. For example, if the light source  130  is a multicolor light source that can emit red, green and blue light, the visual effect can include the color variation by switching among the red emission, green emission and blue emission time by time.

       [0084]    As Embodiment 2, various embodiments employing the illumination system  100  of the present invention are described. 
         [0085]    As shown in Embodiment 1, the illumination system  100  can provide the visual effect if it comprises the reflection board  120  and the light source  130  installed at the predetermined position. 
         [0086]    The application of the illumination system  100  includes the reflection board  120  shown in Embodiment 1 and the light source  130  in the predetermined position relative to the reflection board  120 . 
         [0087]    In addition, the application of the illumination system  100  may include the light source support body  110  for supporting the light source  130 . By utilizing the light source support body  110 , the light source  130  can be supported in the position facing the processed reflection board  120  to obtain the visual effect shown in Embodiment 1. In addition, the light source  130  can be supported by the light source support body  110  on the roof or the wall nearby the reflection board  120 . 
         [0088]    First, the example of the merchandize display fixture  200   a  employing the illumination system  100  of the present invention is described. 
         [0089]      FIG. 7  is a schematic view showing a merchandize display fixture  200   a  employing the illumination system  100  of the present invention.  FIG. 7  ( a ) is the front view,  FIG. 7  ( b ) is the right-side view. 
         [0090]    As shown in  FIG. 7 , the merchandize display fixture  200   a  employing the illumination system  100  of the present invention comprises at least a light source support body  110 , a reflection board  120 , and a light source  130  (not shown in  FIG. 7 ). 
         [0091]    The figure of the light source support body  110  is not limited. For example, the light source support body  110  shown in  FIG. 7  includes plural shelves which are often used in utensil furniture in front of the reflection board  120 . These shelves have depth to some extent, the light sources  130  are installed on those shelves, bodies facing the reflection board  120  for projecting the emission light to the reflection board  120 . 
         [0092]    The light source support body  110  is installed in front of the reflection board  120  at a certain distance as shown in  FIG. 7  ( b ). In other words, the light source  130  is supported in front of the reflection board  120  at a certain distance. 
         [0093]      FIG. 8  is a schematic cross sectional view showing the inner structure of the merchandize display fixture  200  employing the illumination system  100  of the present invention.  FIG. 8  ( a ) is the frontal cross sectional view,  FIG. 8  ( b ) is the vertical cross sectional right side view. 
         [0094]    As shown in  FIG. 8  ( a ), a plurality of light sources  130  are embedded into the shelves of the light source support body  110 , and these light sources  130  are arrayed for projecting the emission light to the reflection board  120 . In this example, the shelves are installed approximately horizontally, LED of the light sources  130  are also installed approximately horizontally, and numerous fine grooves  122  inscribed in the processed reflection plane of the reflection board  120  are arranged approximately horizontally in parallel. 
         [0095]    When the light sources  130  are turned on, the merchandize display fixture can obtain the visual effect as described in embodiment 1 by employing the illumination system of the present invention shown in embodiment 1. 
         [0096]    As described in embodiment 1, the processed reflection plane of the reflection board  120  does not reflect the light as a virtual image like a mirror. It gives people standing in front of the illumination system a visual effect. The reflection pattern makes the watcher feel and recognize as if there is an extended horizontal plane spreading toward the opposite side of the wall, and the light track is recognized as the light track of the head light beam projecting on the extended horizontal plane. 
         [0097]      FIG. 9  is a schematic view showing the visual effect obtained by the merchandize display fixture  200   a  employing the illumination system of the present invention. 
         [0098]      FIG. 10  is a schematic view showing the light tracks  140  of the reflection pattern seen in the trial piece of the actual processed reflection plane of the reflection board  120  (part  1 ). 
         [0099]      FIG. 11  is a schematic view showing the light tracks  140  of the reflection pattern seen in the trial piece of the actual processed reflection plane of the reflection board  120  (part  2 ). 
         [0100]      FIG. 12  is a schematic view showing the image if the reflection plane is a mirror for comparing with the visual effect between the mirror and the processed reflection plane. 
         [0101]      FIG. 9  shows a part of the light source support body  110  simply. The light sources  130  are hidden in the back side of the light source support body  110  for facing the reflection board  120 .  FIG. 9  also shows a part of the processed reflection plane of the reflection board  120  simply. The fine grooves inscribed in the processed reflection plane are not shown in  FIG. 9  to understand the reflection pattern easily.  FIG. 9  shows additional lines drawn by dotted line to assist the description. 
         [0102]    As shown in  FIG. 9 , the emission light emitted by the light source  130  hits the processed reflection plane of the reflection board  120  and forms the light tracks  140  as the reflection pattern. In this example, the watcher recognizes the reflection pattern as the light tracks  140  appear on the reflection board  120 . The example shown in  FIG. 9  is drawn very simply. The light tracks  140  as the reflection pattern are recognized by the watcher as if there is an extended horizontal plane spreading toward the opposite side of the wall, and the light tracks  140  are recognized as the light tracks of the headlight beam projecting on the extended horizontal plane. 
         [0103]    The actual light tracks  140  as the reflection pattern appearing on the processed reflection pattern of the reflection board  120  are shown in  FIG. 10  and  FIG. 11 . As shown in  FIG. 10  and  FIG. 11 , the actual light tracks  140  as the reflection pattern appearing on the processed reflection pattern of the reflection board  120  are actually recognizable as if they were light tracks of a headlight beam projecting on the extended horizontal plane spreading toward the opposite side of the wall. When the watcher watches these light tracks  140 , he will recognize as if there is an extended horizontal plane spreading toward the opposite side of the wall. In  FIG. 11 , several objects are put on the frame of the light source support body  110  to understand the visual effect easily. As shown in  FIG. 11 , the watcher recognizes as if there is an extended horizontal plane spreading toward the opposite side of the wall, but actually there is the reflection board  120  behind the light source support body  110  nearby. This visual effect is one of an optical illusion for recognizing the light tracks  140  as the light tracks of the headlight beam projecting on the virtually extended horizontal plane. 
         [0104]    The light tracks  140  on the processed reflection plane of the reflection board  120  can be seen clearly with high luminance. However, the reflection images of the watcher, the light source support body  110 , and the objects in background are not seen or are hard to recognize compared with the light tracks  140  because of the downgraded reflection ratio of the processed reflection plane inscribed with numerous fine grooves arranged approximately straight in parallel or arranged in a curve approximately parallel to each other. 
         [0105]    In contrast, as shown in  FIG. 12 , if the reflection plane of the reflection board  120  is a mirror, the watcher will see the mirror image simply, such as the light source support body  110  and the light sources  130  embedded into the light source support body  110 . The light sources  130  are seen as high illumination shining positional light sources. In addition, the objects in the background and the watcher himself are seen in the mirror image. Therefore, the watcher can recognize that there is a mirror on the reflection board  120 . 
         [0106]    However, as shown in  FIG. 9 , the merchandize display fixture  200   a  employing the illumination system  100  of the present invention provides the special visual effect as if there is an extended horizontal plane spreading toward the opposite side of the wall even if he may recognize somewhat that a glass-like boundary exists. 
         [0107]    Another merchandize display fixture  200   b  is described as follows. 
         [0108]      FIG. 13  is a schematic view showing another type of merchandize display fixture  200   b  employing the illumination system  100  of the present invention. The light source support bodies  110  are provided as the merchandize display tool and the reflection board  120  is provided as the background board of the merchandize display space. The visual effect allows the customer to feel as if there is an extended horizontal plane spreading toward the opposite side of the wall and allows the customer to feel a calm space around the merchandize. 
         [0109]    As described in embodiment 1, the illumination system  100  of the present invention can provide the special visual effect when it comprises a light source support body  110 , a reflection board which reflection plane is a processed reflection board, a light source  130 , and the light source  130  is supported by the light source support body  110  to face the processed reflection plane reflection board  120 . Therefore, the configuration of the illumination system can be employed in various types of objects and various types of fixtures.
