1.LED (light emitting diode) lighting is the use of the fourth generation of green light LED made of a lighting lamps. LED is known as the fourth generation lighting source or green light source, with the characteristics of energy saving, environmental protection, long life, small size, can be widely used in a variety of instructions, display, decoration, backlight, general lighting and urban night scene and other fields.


Since 2000, a number of economically developed countries in the world have launched a fierce technical competition around the development of LED. The United States invested $500 million since 2000 to implement the national semiconductor lighting program, and the European Union announced the launch of a similar rainbow program in July 2000. Under the support of "863" plan, the ministry of science and technology of China first put forward the plan of developing semiconductor lighting in June 2003.


High energy saving: saving energy without pollution is environmental protection. Dc drive, ultra-low power consumption (0.03-0.06 watts per tube), electro-optical power conversion close to 100%, the same lighting effect than the traditional light source energy saving more than 80%.

Long life: LED light source is called longevity lamp, which means the lamp that never goes out. Solid cold light source, encapsulated in epoxy resin, no loose parts in the lamp body, no filament light burning, heat deposition, light decay and other shortcomings, the service life can reach 60,000 to 100,000 hours, more than 10 times longer than the life of traditional light source.

Multiple changes: the LED light source can make use of the principle of red, green and blue basic colors, and make the three colors have 256 levels of gray under the control of computer technology and mix them at will, so that 256 256 256=16777216 colors can be generated, forming multiple changes of different light color combinations, and realizing colorful dynamic changes and various images.

Benefit environmental protection: environmental protection benefit is better, there is no ultraviolet and infrared ray in the spectrum, neither heat, nor radiation, glare is small, and waste can be recycled, no pollution does not contain mercury element, cold light source, can safely touch, belongs to the typical green lighting light source.

High tip: compared with the traditional monotonous lighting effects, the LED light source is low pressure microelectronics products, successfully combines computer technology, network communication technology, image processing technology, embedded control technology, etc., so also is the digital information technology products, is a semiconductor photoelectric device "high point" technology, the online programming, unlimited upgrade, the characteristics of flexible.
