Explosion-proof light emitting diode (LED) lamp

Abstract

The invention discloses an explosion-proof light emitting diode (LED) lamp, and belongs to the technical field of illumination lamps. The lamp comprises an explosion-proof lampshade upper seat made of a metal material, an explosion-proof lampshade body matched with the explosion-proof lampshade upper seat and an LED lamp device; a mounting hole is formed in the explosion-proof lampshade upper seat; the mounting hole of the explosion-proof lampshade upper seat is matched with the LED lamp device and connected with the LED lamp device in small clearance fit, and the clearance is 0.005 to 0.15 millimeter; and a snap spring is arranged at the joint of the explosion-proof lampshade upper seat and the LED lamp device. By the technology, the conventional first-generation, second-generation or third-generation bulb (light source) in the explosion-proof lamp is replaced by the fourth-generation illumination LED bulb, so that the lamp has good heat dissipation performance, high power-saving capability, long service life and low light attenuation; the explosion-proof LED lamp has the advantages of attractive appearance, simple structure, high explosion-proof performance and convenience in installation and maintenance, and can be popularized and applied on a large scale; and due to good explosion-proof performance and high safety, the lamp is particularly suitable for inflammable and explosive occasions in the industries of petrochemical, mine, chemical engineering and the like.

Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to an explosion-proof LED lamp used in petrochemical, mining, chemical and other inflammable and explosive places. Background technique [0002] In flammable and explosive places in petrochemical, mining, chemical and other industries, explosion-proof lamps are basically used to replace ordinary lighting lamps in order to improve safety performance. At present, there are two types of explosion-proof light sources used, one is thermal light sources, such as metal halide lamps, high-pressure sodium lamps, ordinary tungsten filament bulbs, etc., and the other is fluorescent glass tube energy-saving lamps. These are all traditional light sources, belonging to the first to third generation light sources respectively. The service life of ordinary tungsten filament bulbs is 1500-2000 hours, the service life of metal halide lamps and high-pressure sodium lamps is 3000-40...

AI Technical Summary

Problems solved by technology

These two types of lamps have obvious disadvantages, such as short life, high light decay, high energy consumption, low light efficiency, and sensitivity to peripheral voltage fluctuations. The outer shell is made of glass and is easily broken. Moreover, the lamp contains heavy metals or rare earth materials. There is a very serious problem of environmental pollution. At present, my country does not have a perfect recycling system for such light bulbs. The environmental pollution of such light bulbs has become an unavoidable real problem.
