Led Is New Light Source

Before 1879 Edison invented the electric light, people used candle, kerosene lamp and gas light to light up in the dark, just like its name, the electric lamp is an artificial lighting appliances, it uses electricity as energy, converted electric light energy into light energy, light up the darkness in the open air or in the room. The electric light has greatly promoted the development of the human race in a long time since its invention. But on the other hand, along with the development of human society, human beings find the incandescent light bulb has many shortcomings, it cannot meet the increasing demands, and cannot catch up with the development of the society. Nowadays lighting is not only to satisfy the life needs, more functions are in need, such as commercial lighting, public lighting, and so on, requirements of illume has developed from the original light up the dark to a higher level, lighting tools need beautiful, need to fit environmental, need to send light of a certain intensity.


Used principle of semiconductor PN junction shining, science and technology researcher manufactured LED light emitting diode in the 1960s. In the initial stage of LED development, they used the GaASP material because of this material the color of LED light is red. Now people are more familiar with the LED light source after development of nearly 30 years, it can give out many kinds of colored light for example red, orange, yellow, green, blue and white LED lighting. However, the need is only in recent years developed. Below is about white LED lighting. Using the latest LED light source technology, digital visual design, LED fluorescent lamp can save electricity as high as 70% above.

LED Light almost does not need to maintain and it does not need to change components and parts often and the service life of LED fluorescent lamp is ten times of common fluorescent lamp. The light of Led light is mild, spectrum is pure, and it will help users with eyesight protection and health, so we can say LED light source is the green environmental protection semiconductor electric light source. 6000K of cold light source gives human eyes cool and refreshing feeling, humanized intensity of illumination difference design, can improve the work efficiency for it is more helpful to focus your attention.

There are filament at the tail ends of common fluorescent lamp, the tubes are filled with argon and thin trace mercury steam, fluorescent powder painting, gas in two filament gave a kind of conductive ultraviolet ray, making phosphor soft light. Compared to common fluorescent lamp, the main characteristics of the LED fluorescent lamp are high quality led, durable, energy-saving. LED fluorescent lamps have a projection angle adjustment range, the brightness of 15 W LED fluorescent lamp is equivalent to 40W common fluorescent lamp. It has high temperature resistant, moistureproof, prevent leakage. The voltage is available to 110V and 220V optional, its cover is made of optional glass or PC material, the lamp holder is the same as general fluorescent.

The technolgy of  the LED can be used many industries , for example : LED watches and tokyo flash watches .
