LED lighting-green lighting source

Since the emergence of Light Emitting Diode (Light Emitting Diode), people have been striving to achieve solid-state light sources. With the continuous progress of LED manufacturing technology and the development and application of new materials (nitride crystals and phosphors), LED semiconductor solids The performance of the light source continues to improve and enters the practical stage.

The emergence of white LEDs has enabled high-brightness LED applications to enter the high-efficiency lighting source market. The light-emitting diode is a semiconductor component with a long life; the conversion from electricity to light has high efficiency and low power consumption; at the same time, the light-emitting diode component is a very small light-emitting source, which can cooperate with the miniaturization of various application equipment. Compared with general lighting, white light-emitting diodes save power (the power consumption is 1/8 to 1/10 that of general light bulbs, and 1/2 of fluorescent lamps.

In addition, LED lighting has a long life (up to 100,000 hours or more), low heat generation, (less heat radiation), fast response speed (high-frequency operation possible), and it is safe and environmentally friendly for waste disposal (no mercury pollution) ).

Because of the above-mentioned advantages of LED lighting, it is expected to replace tungsten filament lamps and mercury lamps in the 21st century and become a new lighting source with both power saving and environmental protection. Therefore, it is hailed as the 'green lighting source' of tomorrow. star.
