Greatly expanded the application of LED in the signal display and lighting source areas, automotive interior and exterior lights and traffic lights, including urban transport, railways, highways, airports, seaports, lighthouses, safety warning lights, etc.. Power white LED as special illumination source has started for the automotive and aircraft reading lights, portable lighting source (such as a key light, flashlight), backlight and miners lamps has also been an increasing number of applications. White addition of synthesized by the three primary colors, but also through a specially designed phosphor coated on the GaN blue or ultraviolet wavelength of the power-type LED chip is formed. Power type LED in building decorative lighting, stage lighting, store windows, lighting, advertising light boxes lighting, garden lawn lighting, city night scene compared to their similar products shows its unique characteristics. Use power type RGB tricolor LED, can be made into a compact structure, the tone light source of high luminous efficiency than traditional incandescent light source digital tune, with computer-controlled technology, can be obtained very colorful glow. Power type LED low voltage, low power consumption, small size, light weight, long life, high reliability, it can also serve as the military field, diving, aerospace, aviation, special solid light source. Optimize the design of the progress of the power type LED structure, take the heat and light lining continuously improve its luminous efficiency and luminous flux from multiple 5mm LED lamp panel and lamp assembly will be replaced by power type LED assembly wick. From 1970 to 2000, the last 30 years, the luminous flux every 18 to 24 months to 2-fold increase. Since the advent of the 1998 Norlux Series Power LED, luminous flux increasing trend faster. With the improvement of the performance of power type LED, LED lighting source has attracted greater attention in the field of lighting. General lighting market demand is huge, power white LED technology will be better able to adapt to the application of the general lighting. Sustainable development direction as long as the LED industry, LED solid-state lighting will be achieved in the next five to 10 years, a major breakthrough in the market.
