With the herd phenomenon of the market, as consumers, use LED 400W remains to be calm, scientific analysis, the choice of the best cost-effective light sources and lamps, here are several basic performance of the LED:
1, the brightness of the LED brightness, different prices. LED for LED lamps shall comply with the Laser Level Class I standards.
2, the antistatic ability antistatic ability IR LED Infrared , long life and therefore higher prices. Usually static than 700V LED can be used for LED lighting.
Wavelength wavelength LED, the same color, such as requiring the same color, the price is high. No the LED spectrophotocolorimeter instrument manufacturer it is difficult to produce pure colors products.
4, the leakage current LED is one-way conductive light, if the reverse current is called leakage, the leakage current of the LED, short life, low prices.
5, the use of different light angle of the LED emitting angle. Special light-emitting point of view, higher prices. If all diffusion angle, the higher prices.
6, critical to the quality of life is life, life light bad decision. Light decay, long life, long life and high price.
Chip LED Blue 150W emitter chips, different chips, the price difference. The chip is more expensive in Japan, the United States, generally made in Taiwan and chip prices lower than Japan, the United States.
8, the size of the chip size chip to the side of the quality of the chip LED is better than a small chip. Price proportional to the same chip size.
The colloid ordinary LED colloidal general epoxy resin, plus a more expensive LED UV and fire retardant, high-quality outdoor LED lighting should be UV and fire. Each product will have a different design, different design for different purposes, the reliability of the design of LED lighting include: electrical safety, fire safety, the application of environmental safety, mechanical safety, health and safety, safe use of time and other factors. From the electrical safety point of view, should comply with the relevant international and national standards.
LED strip lights is a new product, the Chinese national standards lag, but the national product qualification testing. LED lighting prices with the international safety certification (such as GS, CE, UL and so on) and the national product quality certification must be high, because these products in the security design is reliable. The attention of consumers is to carefully identify the authenticity of the certificate, certificate of international safety certification and the national product manufacturers are not many.
From health, the price of non-toxic materials designed to be high, especially in indoor LED 200W lighting, do not cheap selection of LED lighting, odor, currently only a few LED manufacturers is produced using non-toxic materials to identify the method can directly with the nose, the smell of products lower than the odor-free price of a lot. Like lead, mercury, cadmium and other toxins need professionals. Look for environmental safety, reliable dust-proof design, the high price of materials, fire protection, UV protection, anti-low temperature cracking of LED products.
