In recent years XiBao field high brightness LED lighting companies, a mineshaft homes in this kind of products in the propaganda GaoLiuMing/watt and long life advantages. However, the LED but need high costs for LED lighting installation and solve the technical problem. Meanwhile, other lighting technology still occupied every link of the lighting industry. For example, because the high-density discharge (HID) GaoLiuMing bulb can provide, good color rendering and a long battery life, in outdoor applications and retail still is very popular.

And early halogen lighting technology, HID can provide higher compared the efficiency. HID metallic halide lamp is the incandescent efficiency in five times, life is 20 times the incandescent. Always HID lamp is through the heavy and bulky, low electromagnetic ballast power, and will appear flicker. Therefore, adopt more effective electronic ballast replace electromagnetic ballast, for existing HID types of markets and new equipment is concerned, will save a lot of energy.

To truly realize the energy saving characteristics, the key still lies in the design of HID electric ballasts. Ballast should play for basic functions, such as power supply, but at the same time bulb glow, it also needs to have some additional performance to ensure strong and reliable design. Moreover, the appropriate rated device should be used to ensure ballast life, while should try to reduce a ballast the elements, to the number of the risk of further reducing the component fault. Now in the market a variety of HID ballasts products, each kind of internal has a and other products are slightly different control circuit. Control circuit generally includes all kinds of integrated circuit, from micro controller to complex ASIC. IR also offer this used for ballast IC, for example IRS2573D, this product will be a lot of devices and technology are integrated in a single single chip, to help simplify design and reduce components number.

Even in more extensive application LED has been the today, HID lighting products is also expected to gain further growth. These lighting technology is the key problem they have high ChuZhuang cost. But its stability determines the speed of investment returns, and each technology in future market further application of speed.
