[0022] like Figure 1 As shown, a heat dissipation structure includes: a cooling component 1, a light source component 2, and a heat dissipation component 3.

[0023] Specifically, the light source assembly 2 includes a reflector 21, a light emitting body 22, and a heat dissipation assembly 3 having an inner cavity 31 (combined with Figure 4), the inner cavity 31 includes a concave cavity 311 adapted to the outer surface of the reflector 21, and the reflector 21 is in contact and connected with the heat dissipation component 3.

[0024] Specifically, the cooling assembly 1 is provided with a cooling air outlet 121 which is in communication with the inner cavity 31 of the heat dissipation assembly 3, and the cooling assembly 1 drives the cooling medium to flow into the inner cavity 31.

[0025] Specifically, the heat dissipation assembly 3 includes a plurality of heat dissipation fins 32 disposed at intervals, and heat dissipation holes 33 communicating with the inner cavity 31 are formed between adjacent heat dissipation fins 32 .

[0026] like Figure 2 As shown, the reflector 21 is provided with a cavity 211 (combined with Figure 1 ), an air inlet 212, an air outlet 213, the light emitting body 22 is installed in the reflector 21, and the air inlet 212 is connected to the inner cavity 31 and the cavity 211 respectively.

[0027] Specifically, the reflector 21 is provided with an open spherical reflective portion 214. In this embodiment, the reflector 21 is a hemispherical structure.

[0028] Specifically, the air inlet 212 coincides with the projection of at least a portion of the light emitted by the light emitter 22 at the reflector 21 , that is, a portion of the light emitter 22 is located directly in front of the air inlet 212 . When the cooling medium enters the cavity 211 from the air inlet 212 , it can be directly blown to the surface of the light emitter 22 .

[0029] Therefore, in the heat dissipation structure of the present application, the light source assembly 2 is installed in the inner cavity 31 of the heat dissipation assembly 3, the reflector 21 is in contact with and connected to the heat dissipation assembly 3, and the heat of the reflector 21 is taken away by the heat dissipation assembly 3.

The heat is conducted to the heat dissipation component 3 through the heat conductive member 9 for heat dissipation, thereby achieving the technical effect of multiple heat dissipation of the cooling plate 8 and the light source.
