The explosion-proof form of explosion-proof lamps is mainly in the product structure, with a certain explosion-proof joint surface or explosion-proof thread, through a whole explosion-proof shell, to withstand the explosion pressure of the explosive mixture that may be generated inside the lamp , the well prevents the explosion to the surrounding explosive mixture to achieve the purpose of explosion protection.

What is a flameproof explosion-proof lamp?

Explosion-proof lamps and lanterns of explosion-proof type, applicable to incandescent lamps, tungsten halogen lamps, fluorescent lamps (including compact fluorescent lamps), high-pressure mercury lamps, high-pressure sodium lamps, self-ballasted high-pressure mercury lamps and metal halide lamps, etc. . Its structural characteristics are first of all that it must have a flameproof enclosure that can withstand the explosion strength test specified in GB3836.2. This integral flameproof enclosure includes the lamp body parts that must be made of metal materials in principle and the matching equipment. Solid lampshade and other transparent parts are divided into two parts. According to the shape of the light source and the distribution of the illuminants, common flameproof lamps can be generally classified into vertical lamps equipped with gas discharge light sources such as incandescent lamps and high-pressure mercury lamps, and horizontal lamps equipped with straight fluorescent bulbs. There are two basic types of lamps. Its common components are lamp body, transparent parts, sealing parts, lamp sockets, inner reflectors and outer lamp umbrellas. And a good flameproof lamp. The main reason for the judgment of the lamp body is to have a reasonable structure of the lamp body and the matching flameproof joint surface, a transparent part that can withstand the impact test and thermal shock test, and use a rubber seal with strong anti-aging ability to fix the lamp body and the transparent part. Equipped with a lamp holder with reliable electrical performance, the luminous flux of the light source inside the lamp is reasonably irradiated to the outside of the lamp through the transparent parts through a reasonably designed inner reflector and an outer lamp umbrella, giving ideal lighting effects in explosion-hazardous places. How to organically combine these elements and make a reasonable layout is the key to the current and future design and development of explosion-proof lamps.
