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, low operating voltage, safe and low voltage, long service life, etc. Therefore, high-power white light LED is an explosion-proof lamp, especially a portable explosion-proof lamp. A very ideal electric light source.
LED explosion-proof lamp is a kind of electrical equipment used in special industries. It mainly deals 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. , which is characterized by:
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 utilizes the characteristics of low calorific value of LED to achieve substantial safety-level explosion-proof, and the LED light source has a long life; the LED maintains a constant brightness during full charge and late discharge; a heat dissipation device is installed on the lamp housing to complete the 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.
