Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] as attached Figure 1 to Figure 3 As shown, the LED explosion-proof lamp of the present invention is composed of LED1, lens 2, radiator 3, aluminum-based circuit board 4, cover plate 5, support plate 6, drive circuit 8 and its protective shell 7 and other components.
[0025] The LED light source is sensitive to temperature, and reasonable heat dissipation measures should be taken to keep the junction temperature of the LED within the rated range during normal operation. In an explosive environment, the LED1 and its driving circuit 8 are installed in a sealed protective casing 7 , and the heat generated by the LED1 needs to be dissipated to the external environment through the protective casing 7 . The present invention adopts the heat sink 3 in the form of a heat sink, utilizes the characteristics of the small size of the LED, and uses the heat...
