SMD LED Lamp Beads 5050 double color RGB high power

What is the working principle of LED strips? From the perspective of LED Light emission, Led Lights are made by encapsulating GaN chips and yttrium aluminum garnet (YAG) together High-Power Purple Lamp Beads. The GaN chip emits blue light (λp=465nm, Wd=30nm), and the Ce3+-containing YAG phosphor made by high-temperature sintering is excited by this blue light and emits yellow light with a peak of 550nm. The blue LED Lamp substrate is installed in a bowl-shaped reflecting cavity, covered with a thin layer of resin mixed with YAG, about 200-500nm Led Chip Processing. Part of the blue light emitted by the LED lamp substrate is absorbed by the phosphor, and the other part of the blue light is mixed with the yellow light emitted by the phosphor to obtain white light. Now, for InGaN/YAG white LED lamps, by changing the chemical composition of the YAG phosphor and adjusting the thickness of the phosphor layer, white light of various colors with a color temperature of 3500-10000K can be obtained Smd Lights With Led. This method of obtaining white light through blue LED lamps has simple structure, low cost, and high technological maturity, so it is most used. This is one of the principles of LED light bar luminescence.
