How to identify tri-proof lights and explosion-proof lights, and how should we choose
The three-proof light refers to waterproof, dust-proof and anti-corrosion, and the explosion-proof light means that there is no spark. To know the difference between explosion-proof lights and tri-proof lights, we need to know their respective definitions.
Definition of explosion-proof lamp
Explosion-proof lamps refer to lamps that are used in dangerous places where flammable gases 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 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 level and explosion-proof form of explosion-proof lamps.
Definition of three-proof light
The three-proof light refers to: waterproof, dustproof and anti-corrosion. Special anti-oxidation and anti-corrosion materials and silicone sealing rings are used to achieve the protection requirements of lamps. This lamp carries out anti-corrosion, waterproof and anti-oxidation treatment on the circuit control board. In view of the weak sealing and heat dissipation capacity of the electrical box, the special working circuit for the intelligent temperature-controlled three-proof lamp reduces the working temperature of the power inverter and isolates the protection circuit against strong electricity. The double insulation treatment of the connector ensures the safety and reliability of the line. According to the actual working environment of the three-proof lamp, the surface of the lamp protective box is treated with nano-spraying, moisture-proof and anti-corrosion, so as to prevent the entry of dust and moisture.
Tri-proof lights are generally used in places with strong corrosive, dusty, rainy industrial lighting needs, such as power plants, steel, petrochemicals, ships, venues, parking lots, basements, etc.
How to choose explosion-proof lights
The selection, installation, use and maintenance of explosion-proof lamps are all indispensable links to ensure the long-term safety, reliability and work of explosion-proof lamps, and they need to be fully paid attention to.
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 the explosive hazardous area, accurately select the explosion-proof category, type, level and temperature group of the lamps.
3. Understand the environmental conditions and work requirements, and reasonably choose explosion-proof lamps with various functions. For example, the enclosure protection level of explosion-proof lamps used outdoors is at least IP43. In places where color identification is required, high-pressure mercury lamps and high-pressure sodium lamps cannot be used for explosion-proof lamps, because these two light sources have poor color rendering.
4. Read the product instruction manual in detail, understand the product's performance, precautions and product limitations, and understand the content of all signs of the product. If there is an "x" symbol after the explosion-proof certificate number, it means that the lamp has a specific applicable place. You should refer to the product instruction manual and nameplate to clarify the applicable place requirements.
How to choose a tri-proof light
Traditionally, due to the needs of different lighting environments, dustproof, moisture-proof, anti-corrosion, explosion-proof, waterproof, etc. may be required, but not every lamp can have these functions at the same time, we are accustomed to have at least one of them. The special lighting fixtures with three functions are called tri-proof lamps, and there are also tri-proof lamps suitable for straight fluorescent lamps called tri-proof lamp brackets.
Dustproof: In some special areas, if there is a requirement for dust-free purification, the lamps and lanterns are required to be dustproof;
Moisture-proof: Some lighting spaces with high humidity must be moisture-proof to avoid damage to the electrical parts of the lamps;
Anti-corrosion: In places such as chemical industry, where the content of corrosive substances such as acid and alkali in the air is high, the lamps have anti-corrosion requirements;
Explosion-proof: For areas such as warehouses, to eliminate the possibility of inflammable and explosive, it is necessary for lamps to be explosion-proof;
Waterproof: For example, outdoor lighting places may encounter rain and other washing, so the lamps and lanterns 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. LED lights can be used as three-proof lights if they are treated with dust-proof, waterproof, explosion-proof (anti-corrosion) treatment.
