Explosion-proof lamp definition:
Let us emphasize again that explosion-proof lamps are used in dangerous places where flammable gas and dust exist, and can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, so as to meet explosion-proof requirements Of lamps. Also known as explosion-proof lamps, explosion-proof lighting. Different flammable gas mixture environments have different requirements for the explosion-proof grade and explosion-proof form of the explosion-proof lamp.
Three-proof light definition:
The three-proof lamp refers to the three-proof: waterproof, dustproof, and anticorrosive. Special anti-oxidation and anti-corrosion materials and silica gel sealing ring are used to achieve the protection requirements of lamps. This lamp carries out anti-corrosion, waterproof, and anti-oxidation treatments on the circuit control board. Aiming at the characteristics of the weak heat dissipation capacity of the electrical box seal, the special working circuit for the intelligent temperature control three-proof lamp reduces the working temperature of the power inverter and isolates the protection circuit from strong electricity. The double insulation treatment of the connector ensures the safety and reliability of the circuit. According to the actual working environment of the three-proof lamp, the surface of the lamp protective box is treated with nano-sprayed moisture-proof and anti-corrosion treatment to prevent the entry of dust and moisture.
Tri-proof lights are generally used in places where industrial lighting needs are relatively corrosive, dusty, and rainy, such as: power plants, steel, petrochemicals, ships, venues, parking lots, basements, etc.
How to choose a suitable explosion-proof lamp:
The selection, installation, use and maintenance of explosion-proof lamps and lanterns are all indispensable links to ensure the long-term safety, reliability and work of explosion-proof lamps and lanterns, and full attention must be paid.
1 The selection personnel must understand the basic working principle of explosion-proof lamps and be familiar with explosion-proof signs.
2 According to the level of explosive hazardous areas, accurately select the explosion-proof category, type, level and temperature group of the lamp.
3 Understand the use environmental conditions and work requirements, and reasonably choose explosion-proof lamps with various functions. For example, the enclosure protection level of explosion-proof lamps and lanterns used outdoors should reach at least IP43. In places where color discrimination is required, explosion-proof lamps such as high-pressure mercury lamps and high-pressure sodium lamps cannot be used, because these two light sources have poor color rendering.
4 Read the product manual in detail, understand the product's performance, precautions and product limitations, and understand the content of all product marks. If there is an “x” symbol after the explosion-proof certificate number, it means that the lamp has a specific applicable place. You should consult the product manual and nameplate to clarify the applicable place requirements.
How to choose a suitable three-proof lamp:
Traditionally, because of the use needs of different lighting environments, it may need to be dust-proof, moisture-proof, anti-corrosion, explosion-proof, waterproof, etc., but not every lamp can have these functions at the same time. We are used to the least of them. Special lighting fixtures with three functions are called three-proof lamps, and three-proof lamps that are adapted to straight tube fluorescent lamps are also called three-proof lamp brackets.
Dust-proof: In some special areas, there are dust-free purification requirements, and the lamps must be dust-proof;
Moisture-proof: In some lighting spaces, where the humidity is high, it must be moisture-proof to avoid damage to the electrical parts of the lamps;
Anti-corrosion: In places such as chemical industry, the content of corrosive substances such as acid and alkali in the air is high, so the lamp has anti-corrosion requirements;
Explosion-proof: in areas such as warehouses, to prevent the possibility of flammability and explosion, the lamps must be explosion-proof;
Waterproof: For example, outdoor lighting places, which may be washed by rain, etc., need to be waterproof.
The essential difference between the two in the core design is that the LED explosion-proof lamp is to protect the safety of the environment, and the three-proof lamp is to protect the service life of the lamp itself. If the LED lamp is dustproof, waterproof, and explosion-proof (anti-corrosion) treatment, it can be used as a three-proof lamp.
