  Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiments described below.

(One embodiment)
First, an embodiment of the structure of the room lighting device of the present invention will be described.
The configuration of one embodiment of the present invention is shown in FIGS. As shown in FIGS. 1 and 2, the indoor lighting device according to an embodiment of the present invention includes a lamp housing 1, a substrate 2, a plurality of light source modules 3, a translucent mask 4, and a reflective mask 5. As shown in FIGS. 2 and 3, the lamp housing 1 of the present embodiment has a circular case, has an opening 11 at the bottom, and has a plurality of heat radiation holes 12 at the periphery thereof. The lamp housing 1 is ventilated outside by a plurality of heat radiation holes 12.

  As shown in FIGS. 2 and 3, the substrate 2 of this embodiment has a circular shape corresponding to the lamp housing 1, and the substrate 2 is accommodated in the lamp housing 1. The substrate 2 has a plurality of through holes 21, and the holes 13 are formed so as to correspond to the light source module 3. In the present embodiment, the substrate 2 is accommodated horizontally in the lamp housing 1, and a plurality of protrusions 22 are installed on the periphery of the substrate 2. Each protrusion 22 is erected on the substrate 2, and a coupling member is passed through a predetermined portion of the lamp housing 1 corresponding to the position of the protrusion 22, so that the substrate 2 and the lamp housing 1 are combined. The As shown in FIG. 4, in this embodiment, the screw 23 corresponds to the coupling member. In the lamp housing 1, holes 13 are formed at locations corresponding to the protrusions 22. The screw 23 penetrates the hole 13 and is screwed to the protrusion 22 to fix the substrate 2 in the lamp housing 1.

  Further, as shown in FIGS. 2 and 3, each light source module 3 includes a light emitting member 31 and a heat radiating member 32. The light emitting member 31 is installed on the opposite side of the substrate 2 from the lamp housing 1. The heat radiation member 32 is installed between the lamp housing 1 and the substrate 2. The heat dissipation member 32 is installed between the substrate 2 and the lamp housing 1. One of the light emitting member 31 and the heat radiating member 32 is provided in the through hole 21 of the substrate 2, and the other is fixed to the substrate 2. As shown in FIG. 5, the heat radiating member 32 of each light source module 3 in the present embodiment has a connection portion 321 that can be penetrated into the through hole 21. This connection part 321 is a thread part in this embodiment. The heat radiating member 32 is fixed to the substrate 2 by coupling the substrate 2 and the connecting portion 321 by the fixing member. In this embodiment, the fixing member is a nut 33 that can be screwed to the connection portion 321. When the light emitting member 31 emits light, the released heat is sucked by the heat radiating member 32, and the heat is conducted to the lamp housing 1 to exchange heat with air. Hot air by heat exchange flows into the lamp housing 1 through the plurality of heat radiation holes 12. Therefore, the effect of radiating heat is achieved.

  As shown in FIGS. 2 and 3, the translucent mask 4 is provided on the opening 11 side of the substrate 1. The reflective mask 5 is installed in the lamp housing 1. The reflection mask 5 is provided between the substrate 2 and the translucent mask 4. The light emitting members 31 of the plurality of light source modules 3 protrude into the reflection mask 5. The upper end portion of the reflective mask 5 of the present embodiment has a shelf portion. The shelf unit 51 is installed under the substrate 2 and in parallel with the substrate 2. The shelf unit 51 has a plurality of holes 511. Each hole 511 corresponds to the light emitting member 31 of each light source module 3. When the light emitting member 31 of the light source module 3 emits light, the light beam is emitted from the direction of the opening 11.

  When the light source module 3 on the substrate 2 fails, the substrate 2 is installed in the lamp housing 1 by the coupling member. Therefore, if all the coupling members are removed from the lamp housing 1, the substrate 2 can be taken out from the lamp housing 1. . In this case, defective products of the light source module 3 on the substrate 2 are replaced one by one. That is, the light emitting member 31 is removed from one end of the connection portion 321 and the fixing member is removed from the connection portion 321. The heat radiation member 32 at this time can be easily removed from the substrate 2, and a new light source module 3 can be mounted on the substrate 2. This completes the replacement work of the light source module 3.

  As described above, when the light source module 3 mounted on the substrate 2 fails, the failed light source module 3 can be easily removed and a new light source module 3 can be replaced. In the prior art, a plurality of LEDs are mounted on an LED light source circuit board, and a technique that cannot be removed is posted. However, compared to the prior art, in the present embodiment, when only some of the LEDs fail and cannot emit light, it is not necessary to replace all the LED circuit boards, so that waste of members can be suppressed.

  By the way, when the shape of the lamp housing 1 is changed to a geometric shape such as a square or an ellipse, the appearance shape of the substrate 2 is changed according to the shape change of the lamp housing 1 and the projections 22 are penetrated by the screws 23. The housing 1 can be fixed. If it carries out like this, when changing the form of the board | substrate 2 and the lamp housing 1, it can mount easily.

  The above-described embodiments are merely for explaining the technical idea and features of the present invention, and are intended to allow those skilled in the art to understand the contents of the present invention and to implement them. It does not limit the scope of the utility model registration request. Therefore, improvements or replacements having various similar effects without departing from the spirit of the present invention are included in the scope of the utility model registration request.
