Brief. Introduction

The illumination using LED start to enter the civil domain massively, Along with semiconductor luminescent device LED unceasingly mature. At present, LED is applied massively in the back light, monitor and commercial illumination. LED has the long life, the highly effective energy conservation, does not have radiation and so on, which already became the new standard of the new generation green illumination. LED substitutes for other photo sources in the illumination domain, that already became the tendency.

Compare with the traditional lamp , This LED fluorescent have following advantages: 

1.The service life is long, may amount to 30,000 - 50,000 hours, design standard life is 10 ten thousand hours by the luminous flux weakens to 70%; 

2.Led tube light is free for the maintenance, using the aluminum + PC structure, not easy break, reliable durable, does not have the tungsten wire and the component which the glass shell is easy to damage, the unusual condemnation factor is very small, the maintenance cost is extremely inexpensive 

3. Energy saving: the illumination brightness of 12W LED tube lamp is equal to the traditional 40W tube lamp, the electricity saving effect is obvious. Generally, the power consumption of 40W energy conservation lamp is 45W to 55W, As the ballast is the inductive character component, energy expended is big; 

4.Response time short when circular pass, the illumination have no twinkle when frequent switching, it can work in the high frequency operation field; 

5.Environmental protection: The reject of led tube light can be recycle, and it does not pollute enviroment, also does not look like the traditional tube lamp include the mercury.

6. High optical efficiency : The spectrum concentrates most completely in the visible light frequency, the efficiency may achieve 80%-90%. But the light effect similar incandescent lamp that the visible optical efficiency is only 10%-20%; 

7.The optical quality is high: In the spectrum, it does not have the ultraviolet ray and infrared that lead to produce the quantity of heat and the radiation, threfore ,  it  belongs to the model green lighting source; 

8.Safe: Unit working voltage approximately between 1.5-5V, operating current between 20-85mA; 

9.No noise: Actuated by constant current , it does not have the noise, but the traditional tube lamp give off heat by ballast, and also cuase the magnetic core noise as operating in high voltage.
