  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments. In addition, about the location where description overlaps, description may be abbreviate | omitted suitably. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  First, with reference to FIG. 1, the lighting fixture 1 of this embodiment is demonstrated. FIG. 1 is a perspective view showing the lighting apparatus 1. The luminaire 1 of the present embodiment is typically used as an outdoor luminaire such as a pole lamp or a garden light.

  As shown in FIG. 1, the lighting fixture 1 includes a housing 2. The housing | casing 2 has the output part 21a. The emission part 21 a is an opening formed on the side wall of the housing 2. The lighting fixture 1 emits light to the outside of the housing 2 from the emitting portion 21a.

  Then, with reference to FIG. 2, the structure of the lighting fixture 1 is demonstrated. FIG. 2 is a cross-sectional view illustrating a configuration of the lighting fixture 1. In detail, FIG. 2 shows the cross section which looked at the lighting fixture 1 from the side. As shown in FIG. 2, the luminaire 1 further includes a lamp body 3, a reflection unit 4, a power supply unit 5, and a support member 6 in addition to the housing 2.

  The housing | casing 2 is installed in the installation surface G like a ground surface or a road surface, for example. In the present embodiment, the vertical direction is defined by setting the installation surface G side as “lower side” and the opposite side as “upper side”. Further, the front-rear direction is defined with the side on which the emitting portion 21 a is disposed in the housing 2 as the “front side” and the opposite side as the “rear side”.

  The housing 2 accommodates the lamp body 3, the reflector 4, the power supply unit 5, and the support member 6. Specifically, the housing 2 includes a cylindrical part 21, a cover part 22, and a base part 23.

  The tubular portion 21 is a tubular member and has an opening on each of the upper end surface and the lower end surface. Hereinafter, the upper opening of the tubular portion 21 may be referred to as “upper opening”, and the lower opening of the tubular portion 21 may be referred to as “lower opening”. In the present embodiment, the cylindrical portion 21 has a rectangular shape. The cylindrical part 21 has a front wall part 211 and a rear wall part 212, and the front wall part 211 has an emission part 21a.

  The cover portion 22 is disposed on the upper surface side of the tubular portion 21 and covers the upper opening of the tubular portion 21. The base portion 23 is disposed on the lower surface side of the tubular portion 21 and covers the lower opening of the tubular portion 21. In the present embodiment, the cover portion 22 is fixed to the tubular portion 21 from the outside of the cover portion 22 by a fixing member such as a screw.

  The lamp body 3 emits light toward the reflecting portion 4. Specifically, the lamp body 3 includes a light source 31 such as an LED (Light Emitting Diode). The light source 31 generates light according to the power supplied from the power supply unit 5. Light generated from the light source 31 is emitted from the lamp body 3. The lamp body 3 may include a lens and a heat sink. By providing the lamp body 3 with a lens, it is possible to efficiently send light toward the reflecting portion 4. Moreover, since the lamp body 3 includes the heat sink, heat generation of the lamp body 3 can be suppressed.

  The reflection part 4 reflects the light incident from the lamp body 3 toward the emission part 21a. As a result, light is emitted from the emission part 21 a to the outside of the housing 2. The luminaire 1 of the present embodiment emits light that illuminates the installation surface G. Specifically, the reflection portion 4 of the present embodiment is a plate-like member, has a curved shape that gently swells upward substantially obliquely, and the inner surface of the reflection portion 4 functions as a reflection surface.

  The power supply unit 5 generates power to be supplied to the lamp body 3. Specifically, the power supply unit 5 includes a power supply device 51. The power supply device 51 is supplied with a power supply voltage from a power supply such as a commercial power supply. The power supply device 51 generates power to be supplied to the light source 31 based on the power supply voltage. For example, when the light source 31 is an LED, the power supply device 51 transforms the AC power supply voltage and converts the AC power supply voltage after transformation into a DC power supply voltage. Furthermore, the power supply device 51 generates a constant current based on the DC power supply voltage. This constant current is supplied to the light source 31.

  The support member 6 supports the lamp body 3, the reflection unit 4, and the power supply unit 5. Specifically, the support member 6 includes a first support member 61, a second support member 62, and a third support member 63. The first support member 61 supports the reflecting portion 4, the second support member 62, and the third support member 63. The second support member 62 supports the lamp body 3. The third support member 63 supports the power supply unit 5.

  More specifically, the support member 6 of the present embodiment supports the power supply unit 5 at a position above the lamp body 3. Therefore, according to the present embodiment, the power supply device 51 is disposed at a position farther than the lamp body 3 with respect to the installation surface G. As a result, compared to a configuration in which the power supply device is arranged closer to the installation surface than the light source, moisture transmitted from the installation surface G through the support column, that is, moisture, is less likely to adhere to the power supply device 51. Therefore, the possibility that a short circuit occurs in the power supply device 51 can be reduced. Moreover, possibility that rust will generate | occur | produce in the power supply device 51 can be reduced.

  In addition, the support member 6 of the present embodiment supports the reflective portion 4 so that the reflective portion 4 is disposed between the lamp body 3 and the power supply unit 5. Therefore, according to the present embodiment, the reflecting portion 4 is disposed between the lamp body 3 and the power supply device 51. As a result, since the lamp body 3 and the power supply device 51 are arranged apart from each other, thermal interference between the lamp body 3 and the power supply device 51 can be suppressed. Therefore, the heat dissipation of the lighting fixture 1 can be improved. In addition, the reflective unit 4 is disposed between the lamp body 3 and the power supply device 51, so that the reflective unit 4 can suppress moisture from adhering to the power supply device 51.

  Further, the support member 6 of the present embodiment supports the power supply unit 5 at the upper part of the housing 2. Therefore, according to the present embodiment, the power supply device 51 is disposed on the upper portion of the housing 2. As a result, moisture transmitted from the installation surface G via the support column is difficult to adhere to the power supply device 51.

  Further, the support member 6 of the present embodiment supports the power supply unit 5 at a position in the vicinity of the cover portion 22. Therefore, according to the present embodiment, the power supply device 51 is disposed in the vicinity of the cover portion 22. As a result, the cover part 22 can be removed from the cylindrical part 21, and the power supply device 51 can be maintained. Therefore, the maintenance work of the power supply device 51 becomes easy.

  Further, in the configuration including the lamp body, the reflection section, and the power supply unit, when the power supply unit is disposed below the lamp body, it is difficult to lower the position of the emission section that emits light. On the other hand, according to this embodiment, since the power supply unit 5 is located above the lamp main body 3 and the reflection part 4, the position of the emission part 21a can be made low easily. In addition, when installing the lighting fixture 1 on the promenade of a park, etc., by making the position of the emitting portion 21a low, it becomes difficult for light to enter the eyes of passers-by on the promenade, and it becomes difficult for passers-by to feel dazzling. . Moreover, since it becomes difficult for a passerby to feel glare, the intensity | strength of the light radiate | emitted from the output part 21a can be strengthened, and the ground can be illuminated brightly and extensively.

  Then, the structure of the lighting fixture 1 is further demonstrated with reference to FIG. As shown in FIG. 2, the lighting fixture 1 includes a first panel 7, a second panel 8, a binding band 9, in addition to the housing 2, the lamp body 3, the reflection unit 4, the power supply unit 5, and the support member 6. And a mounting member 10. The housing 2 further accommodates the first panel 7, the second panel 8, the binding band 9, and the attachment member 10 in addition to the lamp body 3, the reflection unit 4, the power supply unit 5, and the support member 6.

  In the present embodiment, the support member 6 further supports the first panel 7. The 1st panel 7 is arrange | positioned between the reflection part 4 and the output part 21a. The first panel 7 is a spread panel, and spreads the light received from the reflection unit 4 in the horizontal direction. As a result, it is possible to irradiate the installation surface G with light spreading in the lateral direction. Moreover, the boundary of the area | region where light is irradiated in the installation surface G can be given.

  The second panel 8 is a cover member that covers the emission part 21a. The second panel 8 is made of a highly translucent material such as glass. By providing the lighting device 1 with the second panel 8, it is difficult for foreign matters such as insects and dust to enter the housing 2 from the emission portion 21 a. In addition, it becomes difficult for moisture such as rain to enter the inside of the housing 2 from the emitting portion 21a.

  The binding band 9 supports a third power line 113 described later with reference to FIG. The binding band 9 is attached to the first support member 61 and disposed below the lamp body 3. In other words, the binding band 9 is suspended from the first support member 61. Specifically, the first support member 61 has a lower plate portion 611. The lower plate portion 611 is a plate-like portion that extends from the rear side to the front side, and supports the lamp body 3 via the second support member 62. The binding band 9 is suspended from the lower plate portion 611.

  The attachment member 10 is fixed to the cylindrical portion 21 by a fixing member such as a screw. Furthermore, the attachment member 10 is fixed to the installation surface G via the base portion 23 by a fixing member such as a bolt. As a result, the cylindrical portion 21 is attached to the base portion 23 via the attachment member 10. Further, the base portion 23 is fixed to the installation surface G.

  Subsequently, the lighting apparatus 1 will be further described with reference to FIG. FIG. 3 is a cross-sectional view illustrating the configuration of the lighting fixture 1. Specifically, FIG. 3 shows a cross section of the bottom of the housing 2 as viewed from above.

  As shown in FIG. 3, the attachment member 10 has a wiring hole 101 and an attachment hole 102. Both the wiring hole 101 and the attachment hole 102 penetrate the attachment member 10. Similarly, the base portion 23 described with reference to FIG. 2 also has the wiring hole 101 and the mounting hole 102 that penetrate the base portion 23 at positions corresponding to the wiring hole 101 and the mounting hole 102 of the mounting member 10.

  A first power line 111 described with reference to FIG. 4 is inserted into the wiring hole 101. A fixing member such as a bolt is attached to the attachment hole 102. With the base portion 23 installed on the installation surface G described with reference to FIG. 2, the attachment member 10 and the base portion 23 are fixed to the installation surface G by attaching the fixing member to the attachment hole 102.

  Then, with reference to FIG. 4, the lighting fixture 1 is further demonstrated. FIG. 4 is an enlarged cross-sectional view showing the configuration of the lighting fixture 1. Specifically, FIG. 4 shows a wiring configuration of the luminaire 1.
