tri color led (Light-Emitting-Diode Chinese meaning for light-emitting diode) is a kind of energy can be converted into visible light semiconductor, it has changed the incandescent tungsten filament light-emitting energy-saving lamp with three light-emitting color dye-based principle, the use of electric light-emitting.According to analysis, LED is very obvious characteristics, long life, light-efficient, non-radiation and low power.bi color led supply spectrum almost all concentrated in the visible light spectrum, and its luminous efficiency up to 80 ~ 90%. To compare LED with ordinary incandescent lamp, spiral energy-saving lamps and T5 fluorescent trichromatic comparison, results showed that: ordinary incandescent light efficiency to 12lm / W, life expectancy is less than 2000 hours, spiral energy-saving lamps for light efficiency 60lm / W, life less than 8000 hours, T5 fluorescent lamps compared with 96lm / W, life expectancy is approximately 10,000 hours, while the diameter of 5 mm white Super bright LED Manufacturer for 20 ~ 28lm / W, life can be more than 100,000 hours.It was also predicted that the future of superflux led lighting lifetime limit will be infinite.
