LED explosion-proof light is a kind of explosion-proof light. Its principle is the same as that of explosion-proof light, except that the light source is LED light source, which refers to various specific measures taken to prevent the ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. Measure light fixtures. LED explosion-proof lamps are currently the most energy-efficient explosion-proof lamps and are widely used in oil fields, power plants, chemical plants, oil, and troops.
One of the very important explosion-proof principles of LED explosion-proof lamps is to limit the temperature of the surface of the casing, 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 electrical contact surface to be lower than its minimum ignition temperature or ignition temperature . LED explosion-proof lights used outdoors need to use waterproof drivers. LED explosion-proof lights used in gas stations need to be shockproof!
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 operating voltage, long service life, etc., and low energy consumption; therefore, high-power white light LEDs are explosion-proof lamps, especially An ideal electric light source for portable explosion-proof lamps.
LED explosion-proof lights, patented area 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, which mainly solves 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 surface of the lamp housing. : The illuminator is a high-power LED module, and a wide voltage input drive circuit is arranged between the illuminator and the battery; the wide voltage input drive circuit includes a constant current chip, 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 characteristics of low heat generation of LED to achieve intrinsically safe explosion-proof, and the LED light source has a long life; the LED maintains a constant brightness at the end of full charge and discharge; a heat dissipation device is installed on the lamp housing to achieve effective heat dissipation of the LED module. , to ensure the stability of use, suitable for lighting in coal mines, petroleum, railways, flood control and other industries.
