Specifically, in this embodiment, the light source module further includes a light transmissive cover 21, and the light transmissive cover 21 covers the light source board 20 and is connected to the heat dissipation housing.
The working principle is as follows: under normal working conditions of the lamp, heat is transferred to the heat dissipation shell through the heat sink 30 and dissipated through air convection between the heat dissipation holes 111. When the load is reached and the heat dissipation cannot be satisfied, the memory spring 51 is heated and extended along with the temperature rise to a certain value, and drives the plug valve 41 to be separated from the spraying opening, the cooling liquid in the cooling device 40 is sprayed into the heat dissipation cavity 10 from the spraying opening, if the cooling liquid is directly sprayed onto the heat dissipation shell, the light source plate 20 and the heat sink 30, the cooling liquid is vaporized, volatilized and absorbs a large amount of heat, so that the temperature of the whole lamp is instantly reduced, and the abnormal condition of the whole lamp caused by the continuous rise of the temperature is prevented.
