Choose from nine LED light source

As the herd market , as consumers, to choose LED remains calm, scientific analysis , the choice of the best cost-effective light sources and luminaires , LED Here are a few basic properties :
1 , the brightness of the LED brightness , different prices . LED for LED lamps shall comply with the Laser Class Class Ⅰ standards.
2 , antistatic ability antistatic ability of the LED, long life, and therefore higher prices . Typically the static than 700V LED can be used for LED lighting .
3 , consistent with the wavelength of the wavelength of the LED, the same color , the same color as requested , then the price is high . No LED spectral separation device manufacturers is difficult to produce pure colors .
4, the leakage current LED is one-way conductive light , if there is a reverse current is called leakage, leakage current is large LED, short life, low prices.
5 , the use of different light angle LED luminous angle is not the same. Special light-emitting angle , the higher the price . If all diffusion angle , the higher the price .
6 , different quality of life is the key to life, life is determined by the light fades . Light decay, long life, long life , high price.
7, the LED light-emitting body is a wafer chip , different chips , prices vary widely . Japan, the United States more expensive chips , chip prices generally lower than that made ​​in Taiwan and Japan and the U.S. .
8 , the size of the size of the wafer to wafer side expressed great quality LED chips are better than small chips . Chip size is proportional to the price of the same .
9 , colloidal ordinary LED colloidal generally epoxy resin, plus a UV resistant and fire retardant in LED expensive, high- quality outdoor LED lighting should be UV and fire . Each product will be
There are different designs, different designs for different purposes , the reliability of the design aspects of LED lighting include: electrical safety , fire safety, applicable environmental safety , mechanical safety , health and safety,
Safe use of time and other factors . From electrical safety point of view, should be consistent with relevant international and national standards.
       Since LED is a new product , China lags behind national standards , but the state provides product qualification testing . With international safety certification ( such as GS, CE, UL , etc. ) and national product quality certification of LED
Lighting the price is higher , because these products are designed to be safe and reliable . Consumers should carefully note that the certificate of authenticity , there are international and national product safety certification certificate manufacturers
Not much.
       From a health aspect , the use of non-toxic materials designed product prices to be high, especially indoor LED lighting, do not choose the smell of cheap LED lighting, LED manufacturers currently only a few
Is produced with non-toxic materials , the method can be directly used to identify each nose , the smell of the product is lower than the price of many odor -free . Professionals need a similar analysis of lead, mercury , cadmium and other toxins. From fitness
Look with the environment safe, reliable dust-proof design, material fire , UV, anti- low temperature cracking price LED products is high.
