Solid state lighting can be used for 50 years or will replace the traditional incandescent lamp

Since Edison invented the incandescent lamp in 1879, in addition to filament material from the original bamboo fiber to tungsten filament, the basic form is still in use. Fluorescent lamps, although more efficient, but still can not be separated from the electrode and lamp. Now, an all solid state light emitting device, semiconductor light-emitting diode (LED) and organic light emitting diode (OLED) has been a pioneer in the field of special lighting display skills to the full to further enhance the electro-optical conversion efficiency, and reduce costs, will become the field of general lighting.

China's lighting electricity consumption accounted for 12% of electricity consumption, has great potential to save. Today, a highly efficient green all solid state light-emitting devices will be expected to replace the traditional incandescent lamp for centuries - a new type of lighting for 50 years. Since Edison invented the incandescent lamp in 1879, in addition to filament material from the original bamboo fiber to tungsten filament, the basic form is still in use.

Now, an all solid state light emitting device, semiconductor light-emitting diode (LED) and organic light emitting diode (OLED) has been a pioneer in the field of special lighting display skills to the full to further enhance the electro-optical conversion efficiency, and reduce costs, will become the effective way to the field of general lighting energy-saving technology. Where is the God of solid-state lighting. The use of all solid-state light-emitting devices as light source lighting technology, in fact, is not a new thing.

A semiconductor light emitting diode (LED) on the instrument display, mobile phone and digital camera backlighting, full-color display (e.g. square display) in the application of already familiar to people, and is widely used in special lighting. For example, in addition to mark the traffic lights, lights, lights, car lights have been commercialized, with the improvement of people's living standard, the indoor night bright lamp, and public green garden villa building lawn lamp, landscape lamp also favored.

The magic of this lamp lies in: low voltage power supply, long service life, can be selectively issued red, green, blue, white light can also be issued, and very power-saving. Compared with the use of a hundred years of incandescent light, in the same brightness, it consumes only 1/10, life is up to 100 times, is a fluorescent lamp of 10 times. To 6 hours a day, a semiconductor lamp can be used for 50 years, a person can not use a lifetime of the lamp two. Its photoelectric conversion efficiency has been more than incandescent lamp, fluorescent lamp is not yet, is expected to reach 10 times the fluorescent lamp in the next 1.5 years.

Although solid-state lighting to really enter the general lighting market, there is a major breakthrough in technology and cost, which requires a lot of investment and long-term efforts. But it is expected that the market can not resist the charm, it is no wonder that countries have launched a national project to guide and support.
