LED lighting lighting

Under the current background of increasing global energy shortages, energy conservation is an important issue that we face in the future. In the field of lighting, the application of LED light-emitting products is attracting people's attention. LED is a new type of green light source product. It must be the trend of future development. In the 21st century, we will enter the era of new lighting sources represented by LEDs.

 LED is known as the fourth generation lighting source or green light source, has the characteristics of energy saving, environmental protection, long life, small size, etc., can be widely used in a variety of instructions, display, decoration, backlight, general lighting and urban nightscapes and other fields. In recent years, some of the world's economically developed countries have launched a fierce technological competition around the development of LEDs. The United States has invested 500 million U.S. dollars to implement the "National Semiconductor Lighting Plan" since 2000, and the European Union announced in July 2000 that it would launch a similar "Rainbow Plan." China's Ministry of Science and Technology, with the support of the "863" Program, proposed the development of a semiconductor lighting plan for the first time in June 2003.

  LED lights advantages:
  High energy-saving: energy-saving energy is pollution-free. DC drive, ultra-low power (single tube 0.03-0.06 watts) electro-optical power conversion close to 100%, the same lighting effect than traditional light sources, energy saving more than 80%.
  Long life: Some LED light sources call it a longevity light, meaning a light that never goes out. Solid cold light source, epoxy resin encapsulation, there is no loose part of the lamp body, there is no weakness of the filament luminescence, heat deposition, light decay, etc., the service life of up to 60,000 to 100,000 hours, 10 times longer than the traditional light source life the above.
  Changeable: LED light source can use red, green, basket three color principle, under the control of computer technology so that three colors with 256 gray levels and arbitrary mixing, you can generate 256 × 256 × 256 = 16777216 colors to form a different light The combination of colors changes, achieving rich dynamic effects and various images.
  Li environmental protection: better environmental benefits, there is no ultraviolet and infrared light in the spectrum, there is no heat, no radiation, little glare, and waste can be recycled, no pollution, no mercury elements, cold light source, can be safely touched, belonging to the typical green Lighting source.
  High-tech tip: Compared with the monotonous luminous effect of traditional light sources, LED light source is a low-voltage microelectronics product that successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, and so on, so it is also a digital information product. Semiconductor Optoelectronic Devices "high-tech tip" technology, with online programming, unlimited upgrades, flexible features.
