Development of LED's for general lighting purposes Yinchuan showcase light bar manufacturers, people need a white light source. 1998 hair white LED developed. This is the GaN LED chip and yttrium aluminum garnet (YAG) packaged together to make. GaN chip emits blue light (λp = 465nm, Wd = 30nm), issued a yellow YAG phosphor containing Ce3 + after high-temperature sintering of blue excitation light emitted by this peak 550nm. Blue LED substrate is mounted in the reflective cavity bowl Yinchuan showcase light bar prices, covered with a thin layer of resin mixed with YAG, about 200-500nm. The blue part of the LED substrate phosphor emitted absorbed Yinchuan showcase light bar sales, and some blue mixed with yellow phosphor issued, may be too white. For InGaN / YAG white LED, the YAG phosphor by changing the chemical composition and adjust the thickness of the phosphor layer, the color temperature can be obtained 3500-10000K colored white. This method of phosphors excited by the blue LED white light, the structure is simple, low cost, technical maturity, and therefore use the most. LED light source of claim 1 and a brightness LED brightness showcase different lights, different prices. LED for LED lamps shall comply with Laser Class Class Ⅰ standards. 2, the antistatic ability antistatic ability of LED, long life, and therefore higher prices. The LED is usually static than 700V can be used for LED lighting. 3, the same wavelength wavelength LED light bar, and color, such as requiring the same color, the price is high. No LED spectral separation device manufacturer of products difficult to produce pure colors.
