Description of the Invention [Technical Field of the Invention] The present invention relates to a lighting fixture for use in lighting such as roads or parking lots. [Prior Art] Generally, a lighting fixture for lighting such as a road or a parking lot is provided with a light source lamp, and a reflecting plate that reflects light from the light source lamp toward a road surface or a ground (hereinafter, simply referred to as "ground"). Most of the reflectors are cup-shaped (dome-shaped). Conventionally, in such a lighting fixture, it is a main required characteristic to ensure illumination on the ground or to suppress illumination characteristics on the ground such as glare, but in recent years, for example, from the rear of the road lamp to the outside of the road. The light of a house or farmland has become a problem of light damage. Therefore, in addition to the above-mentioned lighting characteristics on the ground, it is necessary to properly illuminate only the place where the illumination is required, and it is required to minimize the light distribution control that does not require light. . As a technique for reducing unnecessary light, as disclosed in Patent Document 1, a technique of arranging a light shielding plate in a reflecting plate is known. However, in the technique of arranging the visor, the light originally intended to illuminate the ground is cut off, so that the lighting efficiency on the ground is deteriorated. [Patent Document 1] JP-A-2003-338215 SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a place where illumination is not required to be deteriorated, and -4-201007084 can be accurately illuminated, and can be reduced as much as possible. Lighting fixtures. A lighting fixture according to the present invention is a lighting fixture including a reflector and a light source lamp inside the panel, and is characterized in that: a reverse plane is formed by combining a plurality of planes, and is disposed in a reflection portion of the light source lamp and disposed in the light source lamp. The upper reflection portion above the rear reflection portion light source lamp and the reflection portion of the light source lamp φ portion are disposed, and the front reflection portion and the rear reflection portion are both forward. In the present invention, the front reflection portion and the rear reflection portion are disposed obliquely toward the front. The rear reflecting portion is configured to greatly reduce the unnecessary light of the light source by the light of the rear reflecting portion facing backward, thereby accurately illuminating the front only light, that is, in the present invention, In order to reduce unnecessary light, Patent Document 1 uses a visor, but reverses (light distribution control) its reflection direction, so that it does not take the illumination in the present invention. Specificity range The shape of the front reflection portion and the rear reflection portion, the inclination angle, and the like, and the specific range of the side of illumination is adjusted by adjusting the shape of the opposite side reflection portion In the invention, the reflecting plate is formed by a combination of a plurality of curved surfaces and a plurality of curved surfaces. Therefore, the reflecting plate has a strong directivity reflected by the "plane" and is not easily attenuated to reach a far distance. When the "plane" is reflected, the reflection of the light can be finely controlled. No light is required. The reflection plate has a front portion that is front and a side that is disposed on the side. The backlight of the light source is directed toward the light source for the rear. It is not the above-mentioned shots that the control efficiency is degraded by adjustment. Part reflection part and control. The light in this "plane" is a device with a multi-directional direction, and -5- 201007084 can correctly illuminate a place where only illumination is required. The reflecting portions of the reflecting plate formed by combining the planes in this manner are formed by flat plates or by bending. By forming the reflecting plate in such a configuration, the reflecting plate can be made more simply, and the cost can be reduced. In addition, when it is desired to obtain stronger light, the mirrors are processed by mirrors, and when soft light is desired, rough processing or embossing is performed. Further, in the present invention, the "light source lamp" is inserted into the reflecting plate from the opening portion provided in the rear reflecting portion, and can be disposed to be approximately horizontal or inserted into the reflecting plate from the opening portion provided in the upper reflecting portion. The inside may be arranged to be approximately parallel to the oblique direction of the front reflecting portion and the rear reflecting portion. However, if the latter arrangement is made, the rear reflecting portion can more reliably reflect the light behind the light source lamp, thereby improving the illumination efficiency. Further, in the present invention, a supplementary reflection plate for reflecting the light from the inside of the reflecting plate toward the inside of the reflecting plate may be disposed between the opposing side reflecting portions. When the auxiliary reflector is disposed, the intensity distribution of the light can be controlled within a predetermined illumination range Ο. According to the lighting fixture of the present invention, the lighting efficiency is not deteriorated, the place where only illumination is required is correctly illuminated, and the unnecessary light is greatly reduced. That is, in the present invention, since the rear reflecting portion reflects the light toward the rear of the light source lamp, the illumination efficiency is not deteriorated, and the light toward the rear of the light source lamp can also be used to illuminate the front side. Compared with the lighting device of the conventional cup-shaped (dome-shaped) reflecting plate, the illumination efficiency in front can be improved. Therefore, it is possible to reduce the number of lighting fixtures, or to reduce the output (wattage) of the light source lamp, and also to save energy. -6- 201007084

[Embodiment 1] Fig. 1 is a longitudinal sectional view showing a first embodiment of a lighting fixture according to the present invention. Fig. 2 is a perspective view showing a reflector of the lighting fixture of Fig. i. It is a top view, (b) is a side view '(c) is a front view. The lighting fixture of the present invention has a reflector 10 and a light source lamp 3 disposed inside the reflector 10. The reflector 10 is a front reflection portion 11' disposed in front of the light source lamp 30, a rear reflection portion 12 disposed rearward of the light source lamp 30, and an upper reflection portion 13 disposed above the light source lamp 30, and disposed on the reflection portion 13 The side reflector portion 14 of the side of the light source lamp 30 _ is formed. First, the front reflecting portion 1 1 is formed by sequentially bending one flat plate, and is inclined toward the front as a whole, and is formed in a shape along an arcuate curved surface which is convex toward the front. The front reflecting portion 1 1 and the opposing rear reflecting portion 1 2 are formed by bending a single flat plate, and are inclined forward as in the front reflecting portion 1 1 and formed along the rear side. The shape of a convex arc-shaped surface. The rear reflecting portion 12 is a flat plate that is not bent, and can be formed simply by a flat plate. On the other hand, the upper reflecting portion 13 is formed by sequentially bending a flat plate in a zigzag manner. Further, the side reflection portion 14 is formed by sequentially bending one flat plate, and the 201007084 is inclined toward the entire side, and is formed in a shape such as an arcuate curved surface which is convex on the side. The reflecting plate 10 is formed by joining the front reflecting portions 11, the rear reflecting portions 12' and the side reflecting portions 13 and the side reflecting portions 14 to form a box having a lower opening. As a result, the reflecting plate 10 is formed by combining a plurality of planes. Further, the reflecting plate 10 (each reflecting portion) is mirror-finished in order to increase the reflectance. Further, in the entire length of the side reflection portions 14 and 14 opposed to the reflection plate 1 经由, the light beam from the inside of the reflection plate 10 is reflected toward the rear of the reflection plate 10 through the entire length thereof. Reflector 20. The light source lamp 30 is inserted into the reflector 10 from the opening 15 provided in the rear reflection portion 12, and is disposed approximately horizontally. One end of the light source lamp 30 is mounted on a socket 41 provided in the luminaire main body 40. Further, the reflector 1〇 is also supported by the fixture body 40. In the above configuration, the light rays directed rearward from the light source lamp 30 are reflected forward by the rear reflecting portion 12 which is inclined forward by φ. Therefore, the unnecessary light of the light source lamp 30 to the rear can be greatly reduced. Further, the light toward the front is still partially straight forward, and the other portion is reflected obliquely downward by the front portion 1 1 which is inclined toward the front. Therefore, by adjusting the shape and the inclination angle of the front reflection portion 1 1 and the rear reflection portion 1 2, it is possible to control the illumination range in the front and rear directions. For example, when the lighting fixture of the present embodiment is placed on the shoulder of the road, it is possible to greatly reduce the unnecessary light on the outside of the road and accurately illuminate the only area in the width direction of the road to be illuminated. Further, the light rays upward from the light source lamp 30 are formed by the upper reflection portion 13 of -8-201007084 in a zigzag manner, and most of them are reflected toward the side reflection portion 14 and by the side reflection portion 14 It is reflected, thereby expanding to the side. Further, the light rays from the light source lamp 30 toward the side are also reflected by the side reflection portion 14 and spread to the side. In this manner, the zigzag-shaped upper reflecting portion 13 and the plurality of planar side-side reflecting portions 14 are combined to illuminate a wide range in the lateral direction, and the shape of the upper reflecting portion 13 and the side reflecting portion 14 are adjusted. The angle of inclination, etc., controls the range of illumination. Therefore, when the φ illuminating device of the present embodiment is disposed on the shoulder of the road, the traveling direction of the road can be widened, and the installation interval can be made wider, and as a result, the number of installations can be reduced. Further, in the present embodiment, the auxiliary reflecting plate 20 is disposed as described above, and the light from the inside of the reflecting plate 1 is reflected toward the rear of the reflecting plate 1A. Thereby, the light to be illuminated in front is reflected by the auxiliary reflector 20 toward the rear of the reflector 1 , and the light below the illumination fixture is exchanged, so that the light intensity under the lighting fixture can be further improved. Φ degree). The degree of enhancement of the illuminance below the lighting fixture is controlled by changing the inclination angle β of the auxiliary reflector 20 (see Fig. 1). Further, it is not necessary to provide the auxiliary reflector 20 when it is not necessary to enhance the illuminance under the lighting fixture. Further, when the illuminance in front of the lighting fixture is to be enhanced in contrast to the embodiment of Fig. 1, the auxiliary panel 20 is provided symmetrically with the first drawing, and the light from the inside of the reflecting plate 10 may be made to face the reflecting plate. 10 internal front reflection.

The lighting fixture of this embodiment also has a reflector 50, and a light source lamp 60 disposed inside the reflector 50. The reflector 50 is a front reflection portion 51 disposed in front of the light source lamp 60, a rear reflection portion 52 disposed behind the light source lamp 60, and an upper reflection portion 53 disposed above the light source lamp 60. And a side reflection portion 54 disposed on the side of the light source lamp 60. The front reflecting portion 51 is formed by sequentially bending one flat plate and tilting it as a whole toward the front and forming a curved arc-shaped curved surface which is convex toward the front. The front reflecting portion 51 and the opposing rear reflecting portion 52 are also sequentially bent by a single flat plate s which are inclined toward the front as a whole, and have a shape which is curved along an arcuate curved surface which is convex at the rear. On the one hand, the upper reflecting portion 53 is formed as a top plate portion by a flat plate Φ. Further, the side reflection portion 54 is formed by sequentially bending one flat plate and forming a curved arc-shaped curved surface which is convex on the side. The reflecting plate 50 is formed by joining the front reflecting portions 5 1 'the rear reflecting portions 52, the upper reflecting portions 513 and the side reflecting portions 504, and forming a box shape that is opened downward. As a result, the reflecting plate 50 is formed by combining a plurality of planes. Further, the reflecting plate 50 (each reflecting portion) is mirror-finished in order to increase the reflectance. The light source lamp 60 is inserted into the reflection plate 50 from the opening 55 provided in the upper reflection portion 53, and is disposed approximately parallel to the oblique direction of the front reflection portion 51 and the rear reflection portion 5 2 in the oblique direction. One end of the light source lamp 60 is mounted on a lamp holder 71 provided in the luminaire main body 7''. Further, the reflecting plate 50 is also supported by the lighting fixture body 70. The illuminating device of the present embodiment having the above configuration also exhibits the same effects as those of the previous embodiment, but in the present embodiment, the oblique direction of the light source lamp 60 and the front reflecting portion 5 1 and the rear reflecting portion 5 2 Arranged approximately in parallel, the rear reflecting portion 52 can surely reflect the light rays toward the rear of the light source lamp holder 60, and can be utilized for front illumination, thereby being compared with the previous embodiment, particularly for the front-rear direction. Strong lighting is possible. That is, the present embodiment is suitable for focusing on the front and rear directions of illumination as compared with the previous embodiment. Further, in the present embodiment, as described above, the light rays directed to the rear of the light source lamp 60 can be effectively utilized for the front illumination, and thus the lighting fixture using the conventional simple cup-shaped (dome-shaped) reflector can be used. In comparison, even if the output (wattage) of the light source lamp is reduced, the same illuminance can be obtained, and energy can be obtained.
