Introduction of LED lights
1, LED lighting products in 1879 with the advent of carbon filament incandescent lamps , lighting technology has been rapid development. Fluorescent lamps, mercury lamps , high / low pressure sodium , metal halide lamps , compact fluorescent lamps , high-frequency and microwave electrodeless fluorescent lamps and other new sources of sulfur endless . To many people’s lives convenient place, but from the date of the invention of the incandescent lamp from , you always had a lot of flaws. Tungsten
heating power consumption, light bulbs fragile, and very easy to make an electric shock. Although energy- saving fluorescent light than incandescent , but because of its material composition containing mercury , a great impact on human health . Lead to a qualitative change in the real lighting technology is LED. Conventional LED lighting products are very different in structure and materials. It is a way to convert electrical energy into visible light semiconductor light emission through the upper and lower electrodes and the intermediate conductive material fitted . And the color of the light changes according to the different material properties.
2, LED cold light source are all solid , as opposed to the traditional incandescent lamp , the smaller, lighter , more robust structure , low voltage and long service life. The optical efficiency definition , LED luminous efficiency is not high , but because of its almost concentrated in the visible light spectrum , the efficiency can reach 80% to 90% . The visible efficiency equivalent incandescent light efficiency is only 10 % to 20% , single LED power is generally 0.05 ~ 1W, to meet different needs. LED as a new non-polluting energy sources, is sure to be recognized around the world .
