LED explosion proof lighting technology is typically led lights used in places which have relatively high risks in explosion, such like chemical plants, mines and gas stations. These places are full filled with explosive mixtures: explosive gas atmospheres, explosive dust environment and methane gas. Specific measurements should be taken before installing corresponding explosion-proof lamps. One of the most important working principles of LED explosive lights is restrict the contact surface of covers/shells with explosive gases or dusts and meanwhile keep the surface temperature of lamp compartments and electronic components under a safe level. Normally, this safe level is set as the minimum ignition temperature of the surrounding explosive gases. That the reason why measurements and tests should be conducted before installing these lamps. Only in the condition of knowing the major constitutions of the gas mixtures that suitable LED explosion proof lamps can be chosen.
LED is classified as a type cold solid lighting source, with high eletro-optical conversion efficiency, lower level of heat generation and longer service life. Thus high-power White-ray LED Explosion Proof Lamps are ideal lighting applications. Once promoted, LED explosion proof lighting technology gain a rapid development in this area.
LED explosion proof lights are mainly composed of lamp shells, lamp covers mounted in front of metal shells, internal lighting sources and batteries, switches and other compartments. Their major properties:
Lighting sources are made up of high-power LED modules. Wide input voltage drives (include constant-current chips, power supplier module) are set between lighting sources and batteries. In most cases, power supplier modules are connected directly with constant-current chips and plastically sealed together with LED modules.
The low heat generation of LED lighting sources helped to realize the internal temperature control property to some degrees. Both in battery-fully-charged phases and in battery-nearly-worn-out phases, LED lighting sources can maintain a constant brightness. Low-power LED explosion-proof lights are usually made as portable. It is a recently-developed technology according to the demand of the market. Heat sinks are set on the surface of shells (within lamp covers), which can effectively conduction unwanted heat created during the operation. LED explosive-proof lamps are more reliable than other LED lighting products and were used in a variety of industries, such as coal, petroleum, railway, etc.
