This heat raises the heat in the light diffusion guide frame 200 and the space inside the light emitting device 1, which is air-cooled by the cutout 230 formed at the four corners of the light diffusion guide frame 200. Can be dissipated. Here, the cutout 230 emits light from the LEDs 320 as described above, since the two air flow paths (the air flow path and the auxiliary air flow path) may form air flows into different spaces. Heat due to light can be easily cooled.

In addition, heat generated in the substrate 310 itself is primarily air-cooled in a space between the support bodies 223, and the heat is transferred to the support body 223, and the transferred heat is supported by the support body ( 223 may be radiated to the outside.

That is, the outer surfaces of the support bodies 223 are physically formed in close contact with the inner surface of the second body 420 of the wading frame 400, which may be formed of aluminum, and thus, the support bodies 223. Heat transmitted to) is transferred to the outer frame 400 through the inner surface of the outer frame 400, whereby the heat can be radiated to the outside through the outer frame 400 to be cooled.

The incision groove 421 is formed to extend laterally along the outer surface of the second body 420, contributing to the reduction of the weight of the outer frame and the increase of the heat radiation effect according to the increase of the heat radiation surface. The cutting groove 421 may be formed in plurality, or may be formed up and down according to the embodiment.

In addition, since the hollow 422 forms a hermetically sealed flow path therein, the hollow 422 can be expected to reduce weight, reduce costs, and cool the air.
