Then , how to pick a good LED lamps do the following reference:
1, LED brightness , different prices . LED lamps should be suitable for LED Laser Level Class Ⅰ standards.
2 , antistatic ability of the LED, long life, and therefore higher prices . Typically the static than 700V LED can be used for LED lighting .
3 , the same wavelength LED, consistent color , such as requiring the same color , the price is high. No LED spectral separation device manufacturers is difficult to produce pure color products .
4 , leakage current , LED is a one-way conductive light , if there is a reverse current is called leakage, leakage current is large LED, short life, low prices.
5 , light angle, its different uses LED emitting angle is not the same . Viewing angle specific higher prices .
6 , life, quality is the key to a different life, life is determined by the light fades . Light decay, long life , high price.
7 , the wafer , LED chips emitting body is , different chips , prices vary widely . Japan, the United States more expensive chips , chip prices generally lower than in Taiwan , Japan , the United States , made a minimum.
8 , colloids, colloidal generally ordinary LED epoxy resin, plus a UV resistant and fire retardant in LED expensive, high- quality outdoor LED lighting should be UV and fire .
