The screws 550 fasten the metal plate 530 to the power storage case 510. The heat radiation fins 560 are attached to the outer periphery of the power storage case 510.

*** Explanation of assembly procedure ***
An assembling procedure of lighting apparatus 900 that is an apparatus according to the present embodiment will be described.

  The lighting unit 300 is assembled as follows.

  First, the attachment member 420 is spot welded to the power storage case 510 and the power circuit unit 520 is inserted into the power storage case 510. A metal plate 530 is fastened to the periphery of the opening of the power storage case 510 in which the power circuit unit 520 is stored with screws 550, and the power terminal block 540 is attached to the metal plate 530.

  Next, the attachment auxiliary member 430 is attached to the attachment member 420, the light source module 410 is applied to the attachment auxiliary member 430 as guided by the attachment auxiliary member 430, and the light source module 410 is attached to a predetermined position of the attachment member 420. . Next, the fixed cover 440 is attached to the attachment member 420 so that the fixed cover 440 covers the light source module 410 and the attachment auxiliary member 430 in a state where the spring 450 is attached to the spring attachment portion 445 of the fixed cover 440. The fixed cover 440 is fastened with screws 460 and the light transmissive cover 470 is attached to the fixed cover 440.

  The lighting unit 300 is attached to the frame 100 as follows.

  As illustrated in FIG. 12, the lighting unit 300 is inserted into the rising portion 120 of the frame body 100 in a horizontal state. At this time, the first convex portion 434 of the attachment assisting member 430 is positioned above the first hole 150 of the rising portion 120, and the second convex portion 453 of the spring 450 is relative to the second hole 160 of the rising portion 120. Position it above. When the lighting unit 300 is pushed down, the first convex portion 434 and the second convex portion 453 are pressed by the inner wall of the rising portion 120 and elastically deformed. When the lighting unit 300 is further pushed down, the first protrusion 434 and the second protrusion 453 reach the first hole 150 and the second hole 160, respectively, and return to their original shapes when they reach the first hole 150 and the second hole 160, respectively. 150 and the second hole 160. Thereby, the illumination unit 300 is fixed to the frame 100.

*** Explanation of the effect of the embodiment ***
In the present embodiment, an attachment auxiliary member 430 for positioning the light source module 410 is installed at a position adjacent to the region where the light source module 410 is fixed on the attachment surface 425. For this reason, according to the present embodiment, the light source unit 400 can be easily assembled.

  In the present embodiment, a part of the attachment auxiliary member 430 is exposed to the outside from the notch 448 on the side surface of the fixed cover 440, and at least the mechanism for fixing the lighting unit 300 to the frame body 100 is exposed to the exposed portion. Some are provided. Specifically, a first protrusion 434 that is caught in the first hole 150 of the frame 100 is provided in a portion exposed to the outside of the attachment assisting member 430. For this reason, according to the present embodiment, the positioning of the light source module 410 on the mounting surface 425 and the fixing of the lighting unit 300 to the frame body 100 are both performed by the mounting auxiliary member 430 that is a single member. Can do.

  A cutout 448 is provided on the side surface of the fixed cover 440 in accordance with a portion exposed to the outside of the attachment auxiliary member 430. For this reason, according to the present embodiment, the fixing cover 440 can also be positioned by the attachment auxiliary member 430.

  In the present embodiment, by adopting a snap fit structure, when the lighting unit 300 is inserted into the frame body 100 from above, the first protrusion 434 and the second protrusion 453 are respectively connected to the first hole 150 and the first protrusion 150. The second holes 160 can be fitted almost simultaneously. For this reason, the workability | operativity at the time of attaching the illumination unit 300 to the frame 100 improves.

  Since the attachment member 420 is separate from the fixed cover 440, it can be made of a material different from the material of the fixed cover 440. Specifically, the material of the attachment member 420 can be an elastic member. Moreover, the 1st convex part 434 can be made conspicuous by making the attachment member 420 into a color different from the fixed cover 440, such as gray and red.

  The fixed cover 440 also functions as a reflector in the lighting unit 300, and reflects light emitted from the light source module 410 and light reflected inside without passing through the light transmissive cover 470 to transmit light. The light can be emitted outside the cover 470. This increases the light extraction efficiency. If the reflectance of the fixed cover 440 is greater than or equal to the reflectance of the substrate 412 of the light source module 410, the light emitted from the LED 411 is particularly easily reflected and emitted to the outside of the light-transmissive cover 470, so that the light extraction efficiency is further improved. Rise.

*** Other configurations ***
In the present embodiment, the lighting unit 300 is fixed to the frame body 100 by the first convex portion 434 and the second convex portion 453 being hooked in the first hole 150 and the second hole 160, respectively. The positional relationship between 434 and the first hole 150 or the positional relationship between the second convex portion 453 and the second hole 160 may be reversed. That is, the first convex portion 434 may be provided in the rising portion 120, and the first hole 150 may be provided in the attachment auxiliary member 430. Moreover, the 2nd convex part 453 may be provided in the standing part 120, and the 2nd hole 160 may be provided in the spring 450 or the fixed cover 440 grade | etc.,.

Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  As shown in FIGS. 13, 14, and 15, in the present embodiment, the attachment auxiliary member 430 does not have the first protrusion 434, and the protrusion 422 of the attachment member 420 becomes the first protrusion. Equivalent to. That is, in the present embodiment, instead of the first convex portion 434 of the attachment assisting member 430 in the first embodiment, the protruding portion 422 of the attachment member 420 is hooked in the first hole 150 of the rising portion 120. Therefore, the first hole 150 is provided at the same position as the attachment member 420 in the height direction, that is, at a position higher than that in the first embodiment.

  The procedure for assembling the lighting unit 300 is the same as that in the first embodiment.

  The lighting unit 300 is attached to the frame 100 as follows.

  As shown in FIG. 16, the projecting portion 422 of the mounting member 420 is inserted into the first hole 150 of the rising portion 120 with the illumination unit 300 tilted. Next, when the lighting unit 300 is pushed down so that the lighting unit 300 rotates around the protrusion 422, the second convex portion 453 is pressed by the inner wall of the rising portion 120 and elastically deforms. When the lighting unit 300 is further pushed down, the elastic force is exerted when the second convex portion 453 reaches the second hole 160 to return to the original shape and fit into the second hole 160. Thereby, the illumination unit 300 is fixed to the frame 100.

  As mentioned above, although embodiment of this invention was described, you may implement combining some of these embodiment. Alternatively, any one or some of these embodiments may be partially implemented. Specifically, any one of those described as “parts” in the description of these embodiments may be employed, or some arbitrary combinations may be employed.
