Analysis of LED explosion-proof lights!

Mobile phone //./ Explosion-proof lamps refer to lamps that endanger various specific measures taken to prevent the ignition of surrounding explosive mixtures such as explosive gas atmospheres, explosive dust environments, and methane gas. One of the most important principles of explosion-proof lighting is to limit the temperature of the surface of the enclosure, the surface of parts or the surface of electronic components that are in contact with explosive gases and explosive dust, and to limit the temperature of the electrical contact surface below its minimum ignition temperature or ignition temperature. . Since LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe and low voltage, long service life, etc., so high-power white light LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal electric light source for lamps. The LED explosion-proof lamp belongs to a kind of electrical equipment used in special industries. It mainly solves lighting problems. It includes a lamp housing, a lamp cover 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 , Its special emblem is: the light-emitting body is a high-power LED module, and a wide-voltage input drive circuit is set between the light-emitting body and the battery. The wide-voltage input drive circuit includes a constant current chip. The constant current chip and the battery form a power supply module. The LED module is connected to the constant current chip, and the power module and the LED module are glued together: the lampshade and the lamp shell are ultrasonically welded. It uses the characteristics of low heat generation of the LED to achieve intrinsically safe explosion-proof, and LED Long lifespan of the light source: The LED keeps constant brightness when the battery is fully charged and at the end of discharge. The heat dissipation device is set on the lamp housing, 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 mines, petroleum, railways, and flood control. Analysis of LED explosion-proof lights! Analysis of LED explosion-proof lights!
