The third radiator H3 includes a plurality of heat radiating fins H3L formed on the upper left surface of the lower panel 13.

(The heat dissipation fins H2L and H3L of the second and third heat sinks are provided on the left and right sides of the lower panel 13 in contact with the first PCB P1 for ensuring a compact structure and optimizing heat dissipation. Have different areas to fit the area width and the size of the room to ensure breathability),

The heat dissipation structure is a plurality of heat dissipation grooves H3U and H3u formed in two stages over the rim of the lower left side of the upper panel 15 and the inner accommodating recess 15B.

The first to third heat sinks H1, H2, and H3 as described above are respectively

Improvement of heat conduction and contact area (to outside air) through heat dissipation projection (H1L) of the lower surface of the lower panel 13 in contact with the first PCB (P1) and heat dissipation projection (H2M) of the fixing guide 19 in contact with the second PCB (P2). Realize heat dissipation through

In addition, as illustrated in [B] of FIG. 8, outside air flows in and out through the upper and lower heat dissipation grooves H2U and H2u of the side wall 11A of the main frame 11.

A gap G is formed between the sidewall 11A of the mainframe 11 and the edge of the window 17.

(In Fig. 9, reference is made to the left middle one-dot chain line circle showing the coupling plane view (upper panel removal) in the left middle).

The plurality of heat dissipation grooves H3U, H3u (H2U, 2D) formed in two stages through the gap G across the lower surface of the left and right short sides of the upper panel 15 and the inner accommodating recess 15B. H2u) to communicate in succession

Since convection occurs between the window 17 and the upper panel 15 and between the window 17 and the main frame 11, the heat dissipation efficiency can be maximized.

As described above, the lighting apparatus A according to the present invention separates the first PCB P1 of the light source unit L, the second PCB P2 of the operation unit C, and the third PCB P3 of the IC chip R, respectively. By providing a structure that individually manages heat generated from each PCB and optimizes heat dissipation management, the heat dissipation efficiency of the entire lighting device is maximized, and the convenience of assembly and maintenance can be greatly improved.

In the above description, the conventionally known techniques related to the light source unit, the LED, the LED control, the light source unit dimming, the material of each component, and the like are omitted, but those skilled in the art can easily infer, infer, and reproduce them.

In addition, in the above description of the present invention with reference to the accompanying drawings with reference to the accompanying drawings having a specific shape and structure, the present invention can be variously modified, changed and replaced by those skilled in the art, such modifications, changes and substitutions It should be interpreted as falling within the protection scope of the present invention.
