In the context of the current global energy shortages, the energy conservation is an important issue for us in the future. In the field of lighting, the application of LED lighting products is attracting the attention of the world. LED is a new type of green light source. It is bound to be the trend of future development. In the 21st century, it will enter the era of new lighting sources represented by LED.

LED is called the fourth-generation illumination source or green light source. It has the characteristics of energy saving, environmental protection, long life and small size. It can be widely used in various fields such as indication, display, decoration, backlight, general illumination and urban night scene. In recent years, some economically developed countries in the world have launched a fierce technical competition around the development of LED. The United States has invested $500 million since 2000 to implement the National Semiconductor Lighting Program. The European Union also announced the launch of a similar "Rainbow Program" in July 2000. With the support of the “863” program, the Ministry of Science and Technology of China first proposed the development of semiconductor lighting plans in June 2003.

Advantages of LED lights:
High energy saving: Energy-saving energy is environmentally friendly without pollution. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts) electro-optical power conversion is close to 100%, the same lighting effect is more than 80% energy saving than traditional light sources.
Long life: Some people call it a long-life lamp, which means a lamp that never goes out. Solid cold light source, epoxy resin package, there is no loose part in the lamp body, there are no shortcomings such as filament light-emitting, heat deposition, light decay, etc. The service life can reach 60,000 to 100,000 hours, which is 10 times longer than the traditional light source. the above.
Multi-variable: LED light source can use the principle of red, green and basket three colors. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, which can produce 256×256×256=16777216 colors to form different lights. The combination of colors is varied, enabling a variety of dynamic changes and various images.
Environmental protection: better environmental protection, no ultraviolet and infrared rays in the spectrum, no heat, no radiation, small glare, and waste can be recycled, no pollution, no mercury, cold light source, safe touch, typical green Lighting source.
High-tech tip: Compared with the monotonous lighting effect of traditional light sources, LED light source is a low-voltage microelectronic product, which successfully combines computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product. Semiconductor optoelectronic device "high-tech" technology, with online programming, unlimited upgrades, flexible and changeable features.
