LED explosion-proof lamp is a kind of lamp whose principle is the same as that of the explosion-proof lamp. Still, the light source is LED light source, which refers to the lamp with various specific measures taken to prevent the ignition of explosive mixtures such as flammable gas, combustible dust, and so on. Therefore, selecting an LED explosion-proof lamp is very important, and we must consider the four technical standards below.
First: LED light source.
We must use high brightness, high efficiency, and low light decline led chips. We’d better choose well-known brand chip manufacturers such as the United States CREE or Germany Osram brand, standard channel chip package led lamp beads, and packaging gold wire/phosphor/insulating glue to meet the material’s requirements. When purchasing, it is best to choose manufacturers specializing in producing industrial lighting lamps, whose products cover lights used in professional fields and all kinds of explosion-proof lighting lamps used in explosion-proof areas.
Second, driving the power supply.
Led is a semiconductor component of DC electronic conversion of light energy. Hence, a good LED lamp requires a high-performance power driver and high power factor to ensure efficiency. The power supply is a crucial factor for the whole lamp, but the quality of the led power supply in the current market could be better and more balanced. A good driving power supply ensures a stable DC supply and comprehensiveimproves conversion efficiency. This parameter reflects the energy-saving type of lamps and lanterns and does not cause waste to the grid.
Third, LED explosion-proof lamps appearance structure close cooling system.
An excellent lamp, in addition to the appearance of a high-grade generous, high-quality light source and power source, but also more important is the rational structure of the shell, which involves the heat dissipation of led lamps, because, at the same time showed the conversion of light energy, there is also a part of the electric energy into heat, the heat needs to be emitted into the air, to ensure the stability of led lighting, The high temperature of the led lamp will cause accelerated light decay, affecting the life of the led lamp. It is worth mentioning that the led chip technology continues to improve, the conversion efficiency is also improved, the amount of electrical energy conversion heat will be less, and the cooling device will use thinner, which will also reduce the cost, conducive to the promotion of Led, but this is only a technical development direction, at present, the shell of the heat or must focus on the parameters.
Fourth, LED explosion-proof lamp lens
.
The refraction of light will cause light loss, and the lens rate also profoundly impacts the final output of the light flux. The lens with a relatively good transmittance can reach more than 93. Because the lens is also expensive, some factories, to save costs, and some cheap lens materials must be secondary, with a transmittance of about 70. It is not apparent to the naked eye to deceive consumers, but it is easy to test the result with the instrument. The lens with relatively poor material will turn yellow and have other undesirable effects after a long time.
