With the the herd phenomenon of the market, as a consumer, the choice of LED is still to be calm. Today, we will introduce how to select the best cost-effective LED light sources and LED light fixtures to you, the followings are the basic points,
1, Different LED brightness different prices. LED for LED light fixtures should comply with Laser Class I standard.
2, The antistatic ability antistatic ability of LEDs, long life, and therefore higher prices. Usually antistatic than 700V LED can be used for LED lighting such as LED downlight fixtures, LED tube fixtures, LED flood light fixtures, LED ceiling light and so on..
3. Consistent wavelength wavelength LED, the same color, such as the requirement that the same color, the price is high. No the LED spectrophotocolorimeter instrument manufacturer is difficult to produce pure colors.
4. The leakage current LED is a one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, short life, low price.
5, Use a different angle of the light-emitting LED Beam Angle. Special light-emitting angle has the higher the price. If all diffusion angle, the price is higher.
6 Different key to the quality of life is life, life is decided by the light fades. Light decay, long life, long life, high price.
7, Chip LED emitters for the chip, different chips, the price difference is large. Japan, the United States more expensive chip, chip prices are lower than the general made in Taiwan and Japan, and the United States.
8, Chips the sizes: the size of the chip to the side of big chip LED quality is better than the small chip. Proportional to the price of the same chip size.
9. Colloidal Ordinary LED colloidal generally epoxy resin, plus LED expensive anti-UV and fire retardant, high-quality outdoor LED lighting should be UV and fire.
Each product will have a different design, different designs for different purposes, LED light fixtures design reliability include: electrical safety, fire safety, for environmental safety, mechanical safety, health and safety, and the safe use of the time and other factors. Electrical safety point of view, should be in line with relevant international and national standards. LED is a new product, the Chinese national standards lag, but the state provides product qualification testing. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of LED light fixtures prices higher, because these products in the security design is reliable. The attention of consumers to be careful identification certificate of authenticity, and now there are not many manufacturers international safety certification and national product certification.
From healthy, non-toxic materials designed product prices higher, especially indoor LED lighting, do not be cheap chosen the smell of LED lighting, only a handful of LED manufacturers currently use non-toxic materials, production, identified direct, respectively, with the nose, the smell of the product is much lower than the price no odor. Like lead, mercury, cadmium and other toxins to be professionals in the analysis. From the applicable environmental safety, reliable dust-proof design, the material fireproof, anti-UV, anti-low temperature cracking LED products price.
