LED explosion-proof lamp refers to the risk place of flammable gas and smoke, which can avoid the current, flame and high temperature that may be caused by the lamp to ignite the flammable gas and smoke in the surrounding environment, so as to achieve explosion-proof lighting. Different combustible gas compounds in the natural environment have different regulations on the protection level and explosion-proof method of explosion-proof lamps. According to the different regulations of the natural environment of flammable gas compounds, the common protection levels of explosion-proof lamps are IIB and IIC, and the explosion-proof methods include full explosion-proof (d) and composite explosion-proof (de). The light sources of explosion-proof lamps can be divided into two categories, one is common fluorescent tubes, metal halide lamps and metal halide lamps. The other is LED light source, which can be divided into SMD light source and COB integrated light source.

    The explosion-proof type of LED explosion-proof light is completely different from the definition of moisture-proof. LED explosion-proof lights are widely used in many industries. During the entire operation process, the LED explosion-proof lamp can show excellent characteristics, and can be safely plugged in without additional mechanical equipment such as electronic ballast stabilized power supply. In addition, explosion-proof lamps mainly show an excellent safety factor. Currently, they are considered lighting fixtures used in high-risk industrial production such as organic chemical companies and oil and gas fields. In terms of protection level, such as LED explosion-proof lights, explosion-proof type and waterproof level are the two major parameters. The moisture-proof rules that people generally call IP65-IP68. The total number of waterproof ratings indicates the following meanings: 6 in IP65 means that no dust enters, and 5 means that all-round watering is not harmful.

    For high-power LED explosion-proof lamps, the problem of heat dissipation has always been the bottleneck restricting the development trend of LED explosion-proof lamps. Electronic refrigeration technology has the advantages of small size, no refrigerant, simple structure, no noise, stability and reliability. With the development of semiconductor device technology and the development status of raw material high network hot spot conversion, it will be of practical significance to use electronic refrigeration technology to deal with the heat dissipation problem of LED explosion-proof lamp lighting system software.
