LED light source selection feature

LED light source selection feature


As the herd of the market, as consumers, use LED still be calm, scientific analysis, the choice of the best cost light sources and luminaires, LED Here are a few basic properties:
1, brightness LED brightness is different, different prices. LED LED lamps for laser level should be consistent with class Ⅰ criteria.
2, antistatic ability Antistatic ability of the LED, long life, and therefore higher prices. The LED is usually static than 700V can be used for LED lighting.
3, the same wavelength LED, and color, such as requiring the same color, 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 reverse current is called leakage, leakage current is large LED, short life, low prices.
5, different lighting angles which uses LED light emitting angle is not the same. Special light-emitting angle, higher prices. If all diffusion angle, higher prices.
6, different quality of life is the key to life, life is determined by the light fades. Light is small, long life, long life, high price.
7, LED chip emitting body for the chip, different chips, prices vary widely. Japan, the United States more expensive chips, generally made in Taiwan and chip prices lower than Japan, the United States.
8, the size of the chip size of the chip to side, said the quality of the big chip LED is better than small chips. Proportional to the price of the same chip size.
9, colloidal ordinary LED colloidal generally epoxy resin, plus a UV LED and fire agents more expensive, high-quality outdoor LED lighting should be UV and fire.
Each product will have different designs, different designs for different uses, LED lighting design reliability comprising: electrical safety, fire safety, for the environment safety, mechanical safety, health and safety, safe use of time and other factors. From the electrical safety point of view, it should comply with the relevant international and national standards. Because 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 national product quality certification of LED lighting prices higher, because these products in the security design is reliable. Consumer attention is to be carefully identified the authenticity of the certificate, there are national and international safety certification product certification are not many manufacturers.
From a health aspect, the use of non-toxic materials designed to be high prices, especially in indoor LED lighting, do not cheap selection of LED lighting odor, currently only a few LED manufacturers is produced using non-toxic materials, identify methods can directly with the nose, respectively, the smell of products lower than the odor-free price of a lot. Professionals need a similar analysis of lead, mercury, cadmium and other toxins. Look from the application of environmental safety, reliable dust-proof design, material fire, UV, anti-low temperature cracking price of LED products is high.
