In industrial and mining workshops with flammable gas and dust environments, 220V AC incandescent lamps are used for lighting fixtures. Because the voltage exceeds the safety voltage of the human body, it is not safe to use; Flammable gases are prone to combustion, dust, and high-voltage electric sparks are prone to burst in contact, resulting in poor explosion-proof performance; LED lights are powered by low-voltage direct current, with low voltage and low heat, making them inherently explosion-proof. Therefore, LED is a more popular explosion-proof light, but for explosion-proof purposes, it is also a necessary condition to solve the heat dissipation problem of LED lights. ZL. 8 'High power cold light source explosion-proof lighting' discloses an LED explosion-proof lamp, whose LED illuminator and driving circuit are separated by zones. However, as stated in the instruction manual, the function of the zones is to install lamp holders [0x4e20] and heat dissipation without considering the isolation of electric sparks. In addition, LED lamps do not have special heat dissipation facilities, and the heat dissipation effect is not good, which is easy to cause cracks due to overheating. The overall safety property is not high.

The LED explosion-proof lamp includes a housing, and the explosion-proof lamp includes a front light source chamber, a rear electric chamber, and a heat dissipation chamber located between them. The light source chamber and electric chamber prevent leakage of electric sparks. Forming a heat dissipation through hole on the peripheral wall of the heat dissipation chamber; The LED module is installed in the light source cavity, and the power driver matched with the LED module is installed in the electrical cavity. The power driver is connected to the LED module. The wire is led out from the electrical cavity to the light source cavity through a sealing device; The heat sink is connected to the LED module in the light source cavity, and the rear end of the heat sink is connected to the heat sink cavity HJTRKjjk587.
