The principle of LED explosion-proof light
One of the very important explosion-proof principles of LED explosion-proof lamps is to limit the temperature of the surface of the shell, the surface of parts or the surface of electronic components in contact with explosive gases and explosive dust, and to limit the temperature of the surface of electrical contact to be lower than its minimum ignition temperature or ignition temperature. LED explosion-proof lights used outdoors require waterproof drivers. LED explosion-proof lights used in gas stations need to be shockproof!
Technical advantages of LED explosion-proof lights
Explosion-proof LED lamp manufacturers Because LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low calorific value, low power consumption, safe and low-voltage operating voltage, long service life, and low energy consumption; therefore, high-power white light LEDs are explosion-proof lamps. , especially a very ideal electric light source for portable explosion-proof lamps.
LED explosion-proof lights, road sealing technology; more in line with the national explosion-proof new technology. It belongs to a kind of electrical equipment used in special industries, mainly dealing with lighting problems. It includes a lamp housing, a lamp shade 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 exterior of the lamp housing. : The light-emitting body is a high-power LED module, and a wide-voltage input drive circuit is arranged between the light-emitting body and the battery; the wide-voltage input drive circuit includes a constant current chip, and the constant current chip and the battery form a power module, and the LED module is connected in On the constant current chip, the power module and the LED module are glued together; the lampshade and the lamp housing are ultrasonically welded.
It uses the low calorific value of LED to achieve practical safety level explosion-proof, and the LED light source has a long life; the battery maintains constant brightness at the end of charging and discharging and the end of discharge; the heat dissipation device is installed on the lamp housing, which can complete the effective heat dissipation of the LED module , to ensure the stability of use, suitable for coal mines, petroleum, railways, flood control and other industries lighting.
