The second mounting surface 42a is inclined with respect to the mounting surface 70a, and is neither perpendicular nor parallel to the mounting surface 70a. More specifically, the second mounting surface 42 a is inclined so that the second light emitting device 30 emits light toward the wall 200. Thereby, the lighting apparatus 10 can illuminate the surroundings of the user with the soft indirect light of the light intensity while operating in the reading light mode.

  The second plate 42 is painted white. Thereby, the light which the 2nd light-emitting device 30 emits is reflected in the 2nd plate 42, and the utilization efficiency of light is improved.

  Each of the plurality of protrusions 42b is formed, for example, by pressing the second plate 42, but may be formed by bonding or welding separate protrusions.

  In the first plate 41 and the second plate 42 described above, for example, L-shaped protrusions formed by cutting and raising one of the first plate 41 and the second plate 42 are the same as those of the first plate 41 and the second plate 42.

[Mounting member]
The attachment member 70 is a plate-like member for attaching the main body 40 of the lighting apparatus 10 to a structure such as a ceiling or a wall. The mounting member 70 is, in other words, a mounting plate. When attaching the lighting fixture 10 to the wall 200, the mounting member 70 is screwed to the wall 200 first, and then the main body 40 is attached to the mounting member 70. As a result, the attachment member 70 is interposed between the main body 40 and the wall 200. The mounting member 70 and the main body 40 are screwed, for example. The mounting member 70 has a mounting surface 70 a facing the wall 200.

  The mounting member 70 is a long plate member, and is formed, for example, by bending a steel plate such as SPCC. The shape of the mounting member 70 as viewed in a direction parallel to the X-axis is rectangular, and the length of the mounting member 70 in the Y-axis direction is substantially the same as the length of the main body 40 in the Y-axis direction.

  A light bulb 75 is disposed on the surface of the mounting member 70 on the main body 40 side. FIG. 9 is a view showing the structure of the surface of the mounting member 70 on the main body 40 side. The surface on the main body 40 side is, in other words, the surface on the opposite side to the mounting surface 70a.

  The light bulb 75 is a so-called bean bulb. The light bulb 75 emits white light of bulb color while operating in the nightlight mode. The light bulb 75 is, for example, an LED light bulb, but may be an incandescent light bulb or the like.

  The light bulb 75 mainly illuminates the Z-axis side (that is, the lower side). Here, in the luminaire 10, miniaturization is achieved by shortening the length in the Z-axis direction, and the optical axis is in the Z-axis direction so that the light bulb 75 emits light toward the Z-axis − side. The bulbs 75 can not be arranged to be parallel to. Thus, the optical axis of the light bulb 75 is inclined with respect to the longitudinal direction of the luminaire 10 so that the light bulb 75 emits light to the second plate 42 side (that is, the Z-axis side). Thus, the amount of light emitted to the second plate 42 side can be increased compared to the case where the light bulb 75 is disposed such that the optical axis is parallel to the longitudinal direction. That is, the utilization efficiency of the light which the light bulb 75 emits can be improved.

The reflection plate 76 is disposed such that the reflection surface of the reflection plate 76 faces the light bulb 75, and the reflection surface faces the light axis of the light bulb 75. The reflection plate 76 is formed, for example, by bending a steel plate such as SPCC. The reflective plate 76 is painted white and has enhanced light reflectivity. According to the reflecting plate 76, the amount of light emitted to the Z axis minus side (that is, the second plate 42 side) can be increased.

  In addition, the opening 42c which passes the light which the light bulb 75 radiate | emits is provided in the part facing the light bulb 75 of the 2nd plate 42 so that the light which the light bulb 75 emits may not be interrupted.

The mounting member 70 has a mounting surface 70a facing the wall 200, and each of the first mounting surface 41a and the second mounting surface 42a is inclined with respect to the mounting surface 70a. The first power supply device 50 and the second power supply device 60 are a surface opposite to the first mounting surface 41 a of the first plate 41 and a surface opposite to the second mounting surface 42 a of the second plate 42. Placed between The wall 200 is an example of a structure.

  Thereby, since the first power supply device 50 and the second power supply device 60 are disposed inside the main body 40, the lighting device 10 has the first power supply device 50 and the second power supply 60 disposed outside the main body 40. Miniaturization is possible more easily than the luminaire. That is, the lighting fixture 10 which is easy to miniaturize is realized. In the lighting device 10, the first light emitting device 20 is disposed on one of the front surface and the back surface of one plate material, and the second light emitting device 30 is disposed on the other of the one surface and the back surface of the one plate material. The heat dissipation of the first light emitting device 20 and the second light emitting device 30 can be further improved.
