Explosion-proof LED lamp is a kind of explosion-proof lamp. Its principle is the same as that of explosion-proof lamp. However, the lamp bead is LED lamp bead. It refers to the various measures taken to prevent ignition of explosive mixtures such as explosive gas environment, explosive dust environment and gas. A specific measure of luminaires. One of the most important explosion-proof principles of explosion-proof luminaires is to limit the temperature of the surface of the enclosure in contact with explosive gases, explosive dust, the surface of components or the surface of electronic components, and to limit the temperature of electrical contact surfaces below their minimum ignition or ignition temperatures.
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 voltage and low voltage, and long service life. Therefore, high-power white LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal electric light source.
LED explosion-proof lamp, which belongs to a kind of electrical equipment used in special industries, mainly solves lighting problems. It includes a lamp housing, a lamp cover disposed at the front end of the lamp housing, an illuminator and a battery disposed inside the lamp housing, and a switch disposed on the surface of the lamp housing. , which is characterized by:
The illuminant is a high-power LED module, and a wide voltage input driving circuit is arranged between the illuminant and the battery; the wide voltage input driving circuit comprises a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected at a constant On the flow chip, the power module and the LED module are glued together; ultrasonic welding is performed between the lamp cover and the lamp housing.
