First, understand led explosion-proof lights
Many people know that explosion-proof lights include LED explosion-proof lights, and the principle is basically the same. It's just that the light source of the LED explosion-proof lamp is derived from the LED light source, which is a kind of lamp that can effectively prevent ignition and explosion of the surrounding environment. Its scope of application includes gas gas, explosive dust environment, explosive gas environment and so on.
Second, the technical advantages of led explosion-proof lights
1. Ideal light source
Because LED is a solid-state cold light source, it has a long service life, the use voltage is a safe low voltage, and it has less power consumption and heat generation, high electro-optical conversion efficiency, and low energy consumption, so use led The LED explosion-proof lamp as a light source is a very ideal light source.
2. Excellent explosion-proof technology
The circuit sealing technology used by the Led explosion-proof lamp is a patent, and its explosion-proof technology can meet the requirements and regulations of the country. It is a kind of top-use electrical equipment for special industries.
3. Low heat dissipation
The calorific value of led explosion-proof lamp is very low, so it is a very safe explosion-proof lamp, which can be used for lighting in various industries.
Through the above content, you can understand the technical advantages of LED explosion-proof lights and what they include.
Explosion-proof structure
The explosion-proof structure type of explosion-proof lamps should be determined according to the regional level and scope of the explosive gas environment. For example, explosion-proof lamps must be used in Zone 1; fixed lamps in Zone 2 can adopt explosion-proof and increased safety types, and mobile lamps must be used. Adopt explosion-proof type. The class or group of the selected explosion-proof lamp should not be lower than the class and group of the explosive mixture in the explosion-hazardous environment. At the same time, the influence of the environment on the explosion-proof lamp should be considered, and it should meet the requirements of various environments such as ambient temperature, air humidity, corrosive or polluting substances. The protection level and anti-corrosion level of lamps and lanterns should be selected according to different environmental requirements. Especially in the presence of corrosive gases in explosive gas environments, it is crucial to choose lamps with corresponding anti-corrosion properties.
In petrochemical enterprises, the lighting fixtures in explosion-hazardous occasions mainly use flameproof type. With the wide application of increased-safety electrical equipment in Zone 2 explosion-hazardous occasions, increased-safety and compound lighting fixtures are also being used more and more. On the basis of certain explosion-proof performance, increased safety lamps have the advantages of light weight, low price, convenient installation and maintenance, and long service life compared with explosion-proof lamps. The most widely used composite electrical equipment in petrochemical enterprises is the increased safety-explosion-proof composite explosion-proof electrical equipment, which generally consists of three parts: flameproof components, increased safety terminals and increased safety enclosures. performance, but also has the advantages of increased safety.
