LED explosion-proof lamp installation to ensure reliable
LED is a light-emitting diode made of a compound containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc., and can emit visible light when electrons and holes are combined, so that it can be used for making As a light-emitting diode, LED is called the fourth-generation light source. It has the characteristics of energy saving, environmental protection, safety, long life, low power consumption, low heat, high brightness, waterproof, miniature, shockproof, easy dimming, concentrated beam, and easy maintenance. Can be widely used in various fields such as indication, display, decoration, backlight, general lighting.
The LED explosion-proof lamp housing is formed by high-pressure aluminum alloy casting, and the surface is sprayed with high-pressure electrostatic spray to effectively provide the heat dissipation performance of the shell. The aluminum substrate is closely attached to the aluminum alloy shell, which can instantly convert the point heat source into a surface heat source. The heat dissipation area is multiplied, which facilitates the rapid dispersion of heat and improves the heat dissipation efficiency; the surface of the casing has a split-distribution groove, which removes heat by means of air flow; the heat sink has a high density, which greatly provides a heat dissipation area, fully guarantees the heat dissipation requirement of the LED, and has a service life. Longer.
The use of LED explosion-proof lamps is very important for lighting in hazardous industries. In order to achieve good lighting and explosion-proof effects, the outer casing of LED explosion-proof lamps is made of cast aluminum alloy, while the transparent parts are generally made of tempered glass, and the surface can also be sprayed with anti-corrosion materials. . The inside of the lamp body of the LED explosion-proof oil depot lamp may generate arcs and sparks when it is used, and it may cause an explosion when it encounters an inflammable and explosive gas outside. The flameproof LED explosion-proof oil tank lamp housing can withstand internal explosion without damage. It can also ensure that the internal flame gas reduces energy when it propagates through the gap, which is not enough to detonate the gas in the outer casing.
The LED explosion-proof lamp should be checked from the nameplate and the product manual before installation: explosion-proof type, category, grade, group; protection grade of the enclosure; installation method and fastener requirements for installation. The installation of the LED explosion-proof lamp should ensure that the fixing is firm and the fastening bolts should not be replaced arbitrarily. The spring washers should be complete. The sealing ring for dustproof and waterproof should be placed as it is when it is installed. At the cable entry point, the cable and the sealing gasket should be closely matched. The section of the cable should be round, and the surface of the sheath should not have defects such as bumps. The excess inlet port shall be sealed according to the type of explosion-proof, coated with 201 displacement type anti-rust oil, and the compression nut is tightened to seal the inlet port. Led explosion-proof lights in places with strong vibration, use anti-fall ring to prevent the lamps from falling off.
Do you understand the nameplate information of the LED explosion-proof lamp?
As an operator of qualified LED explosion-proof lamps, you need to know some necessary LED explosion-proof lamps. Among them, the nameplate information for LED explosion-proof lamps needs to be clear, among which:
1. Explosion-proof mark.
2, the basic signs: including product name, model, manufacturer name, registered trademark, date of manufacture, etc.
3, performance safety signs: including rated voltage, current, nominal frequency, source power and quantity, allowable ambient temperature (this range is only -20 ~ +40 ° C when not marked), specific applicable environmental signs (if applicable only The product of an explosive gas mixture shall be marked with the name or molecular formula of the flammable gas, and the classification mark of the luminaire (such as 'numbers').
4, the explosion-proof certificate number, to prove that the product has been officially tested by the explosion-proof inspection station. Some products have an "x" symbol after the explosion-proof certificate number, which indicates that the product can only be used under certain special safe use conditions. The specified conditions should be clearly marked in the lamp housing or product manual.
5. Additional instructions. In addition to the above markings, the detailed instructions necessary to ensure proper installation, use and maintenance shall be given on the luminaire, on the ballast built in, or in the manufacturer's product manual supplied with the luminaire.
