The characteristics of LED lamps
With the development of new materials and technology improvement, LED lighting to highlight and full color change. Gallium nitride base blue LED, also extends the application domains of LED. The current LED applications includes large screen color display, lighting, laser imaging, multimedia, LCD background light source, detector, traffic lights, instrumentation, optical fiber communication, satellite communication, optical communication and ocean image recognition, but it is mainly used for lighting and display.
LED is composed of superconducting luminous crystal to produce high strength light, it emits little energy, unlike the incandescent lamp that waste too much heat, unlike fluorescent lamp that consumption of high energy and produce toxic gases, like neon lights that require high voltage and easy to damage. LED has been recognized worldwide as a new generation of environmentally friendly high-tech light source.
LED has the advantages of high light efficiency, than the traditional neon lamp energy saving more than 80%, safe and reliable work. LED changed the incandescent tungsten filament light and energy saving lamp three-Toner light-emitting principle, and the electroluminescent. LED wash wall lamp with a long life, high luminous efficiency, no radiation and low power consumption. LED spectroscopy to focus almost entirely on visible light spectrum, the luminous efficiency of up to 80% ~ 90%. LED and ordinary incandescent lamp, energy saving lamp and T5 three fluorescent lights were compared, the results showed: the common incandescent lamp light effect as 12lm / W, life is less than 2000h; spiral energy saving lamp light effect as 60lm / W, life is less than 8000h; T5 three band fluorescent lamp light effect for 96LM life is about 10000h / W, 5mm diameter; and the white light LED light effect as 20 ~ 28lm / W, life can be more than 100000h.

In 1879 Edison invented the carbon filament incandescent lamp, lighting technology will enter a new era. Review twentieth Century lighting history, fluorescent lamp, mercury lamp, high / low pressure sodium lamp, metal halide lamp, compact fluorescent lamp, high frequency electrodeless fluorescent lamp and microwave sulfur lamp light source emerge in an endless stream. Incandescent lamp from the advent of the day with congenital defects, a tungsten filament heating energy consumption, the bulb is fragile, and easy to make people get electric shock. Fluorescent lamp though than incandescent lamp energy saving, but the vision is adverse, the lamp tube Mercury also harmful to human body and environment. The real cause qualitative change or LED lighting technology. Compared with traditional lighting technology, LED is the biggest difference between different structures and materials, it is capable of converting electrical energy into visible light in the semiconductor, upper and lower two layers of electrode is provided, the middle conductive materials, luminous materials in the two electrode layer, the color of the light according to material properties vary change.
LED belongs to the solid cold light source, smaller volume, lighter weight, firmer structure, and low working voltage, long life. According to the usual definition of the efficiency of light, the luminous efficiency of LED is not high, but because the LED spectrum to focus almost entirely on the visible light band, efficiency can reach 80% ~ 90%. And the same luminous efficiency incandescent lamp visible efficiency is only 10% ~ 20%. Monomeric LED power is generally 0.05 ~ 1W, through the cluster mode can meet the different needs of.
LED lighting products is the use of LED as a light source manufactured lighting, lighting in the area of LED light-emitting products application is attracting the world's attention. LED as a new type of green lighting products, is the future trend, twenty-first Century will enter LED as the representative to the era of new lighting source.
