Explosion proof lamps refer to lamps with various specific measures taken to prevent ignition of explosive mixtures around, such as explosive gas environment, explosive dust environment, gas gas, etc. One of the most important explosion-proof principles of explosion-proof lamps is to limit the temperature of shell surface, component surface or electronic component surface in contact with explosive gas and dust, and limit the temperature of electrical contact surface to be lower than its minimum ignition temperature or ignition temperature.

As LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat, low power consumption, safe low voltage working voltage, long service life, etc., so high-power white LED is an ideal electro-optical source for explosion-proof lamps, especially portable explosion-proof lamps.

LED explosion-proof lamp is a kind of electrical equipment used in special industries, which mainly solves the lighting problem. It includes a lamp housing, a lampshade arranged at the front end of the lamp housing, a luminous body and a battery arranged inside the lamp housing, and a switch arranged on the surface of the lamp housing. It is characterized in that: the luminous body is a high-power LED module, and a wide voltage input drive circuit is arranged between the luminous body and the battery; The wide voltage input driving circuit includes a constant current chip, the constant current chip and the battery form a power module, the LED module is connected to the constant current chip, and the power module and the LED module are sealed together; The lamp cover and lamp shell are welded by ultrasonic wave.

It takes advantage of the low heat value of LED to achieve intrinsically safe explosion-proof, and the LED light source has a long life; The LED of the battery keeps constant brightness at the end of full charge and discharge; The heat dissipation device is set on the lamp shell, which can realize the effective heat dissipation of the LED module and ensure the stability of use. It is suitable for lighting in various industries such as coal mine, petroleum, railway, flood prevention, etc.
