Characteristics of White LED

Since the world's first commercial white LED (blue LED chip + yag: yellow phosphor) was manufactured by Nichia, white light LED has revolutionized the field of lighting, judging from the history of human lighting. It is known as the most likely to replace the traditional lighting equipment such as incandescent lamps, fluorescent lighting technology of the fourth generation.

It has the following characteristics:

1）Energy saving and environmental protection. White LED is a novel energy-saving lighting source because of its low energy consumption and high luminous efficiency. The LED is now more efficient than incandescent lamps for general lighting, but uses far less power than incandescent lamps. In addition, now widely used energy-saving lamps, such as fluorescent lamps, their lamps contain environmental pollution chemicals Hg, which is easy to bring harm to the environment. White LED does not contain toxic substances, so it is a "green" lighting equipment.

2) long life. The lifespan of white light LED is generally tens of thousands of hours, while that of ordinary incandescent lamp is about 1000 hours, and that of fluorescent lamp is not more than 10, 000 hours. This shows that the life of white LED is obviously higher than that of ordinary lighting equipment.

3）Solid, small size, easy to design a variety of products. White LED is a kind of solid state lighting source which is fixed and encapsulated by epoxy resin. It has no fragile parts and can withstand some mechanical damage. At the same time, the white LED shape is exquisite, can be developed into a variety of shapes of products, can be simple plane packaging, but also used in complex stereo lighting system.

4) Color temperature, color rendering and brightness are almost close to those of fluorescent lamp, but the reaction speed is faster.

5) the drive current is low DC voltage, which is safe and easy to realize by computer system.

6）Automatic control of the source circuit.
