Three-proof lamp refers to waterproof, dust-proof and anti-corrosion. Explosion-proof lamp means no sparks. Some explosion-proof lamps include three-proof, but three-proof lamp does not include explosion-proof. If you want to know the difference between explosion-proof lights and tri-proof lights, we need to know their respective definitions. The following is an introduction by Yangzhong Hengyuan Lighting.

　　Explosion-proof lamp definition:

　　Explosion-proof lamp refers to a lamp used in dangerous places where flammable gas and dust exist, and can prevent the arc, spark and high temperature that may be generated inside the lamp from igniting the flammable gas and dust in the surrounding environment, so as to meet the requirements of explosion-proof. 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. Refer to GB3836 and IEC60079 for details.

　　1. Suitable for hazardous locations in zone 1 and zone 2 of explosive gas environment;

　　2. Suitable for IIA, IIB, IIC level explosive gas environment;

　　3. Suitable for areas 20, 21, and 22 of combustible dust environment;

　　4. It is suitable for the environment where the temperature group is T1—T6.

　　 Three-proof light definition:

　　 Three-proof lamp refers to the three-proof: waterproof, dustproof, and anti-corrosion. 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 of the electrical box seal, the intelligent temperature control three-proof lamp special working circuit 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.

　　Three-proof lights are generally used in places where industrial lighting needs are more corrosive, dusty, and rainy, such as: power plants, steel, petrochemicals, ships, venues, parking lots, basements, etc.
