The difference between LED explosion-proof lights and traditional metal halide explosion-proof lights

The difference between LED explosion-proof lamp and traditional metal halide explosion-proof lamp LED explosion-proof lamp is a kind of explosion-proof lamp, and its principle is the same as that of explosion-proof lamp, except that the light source is LED light source, which is to prevent the surrounding explosive mixture such as explosive gas environment and explosive dust from being ignited. Lamps and lanterns that take various specific measures for the environment, gas, etc. LED explosion-proof platform lights are suitable for fixed lighting in flammable and explosive places such as petrochemical equipment, petroleum platforms, gas stations, oil pump rooms, and transfer stations. Explosion-proof mark: Exd II BT Gb Protection level: IP It uses the characteristics of low heat generation of LED to achieve intrinsically safe explosion-proof, and the LED light source has a long life; the battery is fully charged and the LED remains constant at the end of discharge; it is set on the lamp housing The heat dissipation device can realize the effective heat dissipation of the LED module and ensure the stability of use. It is suitable for lighting in various industries such as coal mines, petroleum, railways, and flood control. The light-emitting body is a high-power LED module, and a wide voltage input drive circuit is set between the light-emitting body and the battery; the wide voltage input drive circuit includes a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected to the constant On the flow chip, the power module and the LED module are glued together; the lampshade and the lamp housing are ultrasonically welded. In the past, in petrochemical enterprises, explosion-proof lighting fixtures were mainly used in explosion-dangerous places. With the wide application of increased-safety electrical equipment in explosive hazardous areas, increased-safety and composite lighting fixtures have also been increasingly used. On the basis of certain explosion-proof performance, safety-increased lamps have the advantages of lighter weight, lower price, convenient installation and maintenance, and long service life compared with explosion-proof lamps. The most common composite electrical equipment used in petrochemical enterprises is increased safety-flameproof composite explosion-proof electrical equipment, which is generally composed of explosion-proof components, increased-safety terminal blocks and increased-safety enclosures. It has both flameproof safety Performance, and has the advantage of increased safety.
