LED light source of claim 1, the size of the chip size of the chip to side expressed great quality LED chip is better than small chips. Chip size is proportional to the price of the same. 2, LED colloidal colloid ordinary general epoxy resin, plus a UV LED and fire agents more expensive, high-quality outdoor LED lighting should be UV and fire. Development of LED's for general lighting purposes, people need a white light. 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), Yangling box lights supplier, high-temperature sintering of YAG containing Ce3 + phosphors excited by this yellow and blue light emission after the peak 550nm. Blue LED substrate is mounted in the reflective cavity bowl, covered with a thin layer of resin mixed with YAG, about 200-500nm. The blue part of the LED substrate phosphor emitted absorbed, mix yellow box lights Yangling price, some blue and phosphor emitted light box lights, can 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. Yangling box lights _ Chun away illumination (certification) _ Chun away from the light box lights lighting Limited. Lighting Co., Ltd.
