Explosion-proof LED lamp

Abstract

The invention discloses an explosion-proof LED (light-emitting diode) lamp and belongs to the technical field of illumination. The explosion-proof LED lamp comprises a lamp body, a lamp holder, a lampcover and an outgoing guide sleeve, wherein the lamp body is connected with the lamp holder through four stop screws; the outgoing guide sleeve is in threaded connection onto the lamp cover; a heat shield is fixedly connected into the lamp cover; a circuit board is fixedly connected into the heat shield; a heat collection housing is fixedly connected into the lamp body; an LED aluminum substrateis fixedly connected with one end, far away from the lamp holder, of the heat collection housing; a plurality of LED lamps are connected onto the LED aluminum substrates; reflection cups are mounted on the LED lamps; a convex lens is further fixedly connected into the lamp body; and a wire is connected between the circuit board and the LED aluminum substrate. According to the explosion-proof LED lamp, the sealability of the lamp body can be improved by collecting heat dissipated from LED light sources; an explosion-proof barrier is provided at last; dust explosion can be inhibited even if a poor sealing situation appears; the safety protection of the explosion-proof lamp is significantly improved; and the probability of safety accidents due to a problem of the explosion-proof lamp is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of illumination, and more specifically, relates to an explosion-proof LED lamp. Background technique [0002] Explosion-proof LED lamp is a kind of explosion-proof lamp. Its principle is the same as that of explosion-proof lamp, except that the lamp bead is an LED lamp bead. One of the very important explosion-proof principles of explosion-proof lamps is to limit the temperature of the shell surface, component surface or electronic component surface that is in contact with explosive gas and explosive dust, and limit the temperature of the electrical contact surface below its minimum ignition. Temperature or ignition temperature, because LED is a solid-state cold light source, it has the advantages of high electro-optic conversion efficiency, low heat generation, low power consumption, safe and low working voltage, and long service life, so high-power white LED is an explosion-proof lamp. Especially a very i...
