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.
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 .
Because 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 operating voltage, and long service life. Therefore, high-power white light LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal electric light source for 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 light-emitting body is a high-power LED module, and a wide-voltage input driving circuit is arranged between the light-emitting body and the battery; the wide-voltage input driving circuit includes a constant current chip, and the constant current chip and the battery form a power module, and the LED module is connected to the constant current. On the flow 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.
Suitable for Zone 1, Zone 2 hazardous locations, IIA, IIB, IIC explosive gas environment.
Example
LED explosion-proof platform light is suitable for fixed lighting in flammable and explosive places such as petrochemical installations, oil platforms, gas stations, oil pump rooms, transfer stations, etc.
