What Should You Know About LED? From:www.lgiled.com   Reporter:pamela   Date:2013/12/30 9:27:01   Tags:waterproof-led-module

With the rapid development of both science and technology, every one living in this changeable and progressing world should equip themselves with latest knowledge.

Take LED for an example. We widely used LED productions, like led downlight, in many fields of our normal life and work environment. However, we do not know it very well. As a matter of fact, LED is short for Light-Emitting Diode which is a luminous semi-conductor electric component. This electric component appeared in 1962. But, in the early time, it can only emit red light of low luminous intensity. Then it develops into many other monochromatic light versions. Till now,there are visible lights, infrared rays and ultraviolet rays. Of course,during this process,the luminous intensity also has been improved. The applications used as indicating lamp and display board in the earlier time have been applied in many other fields such as display device, television lighting decoration and lighting, with the constant progress of technology.

Besides, it can not be denied that the most popular and most widely used product of LED is LED tubes.It is known to us all that LED Tubes are now getting more and more popular in Home Furnishing field. As a matter of fact, a LED Tube is also commonly known as light pipe and fluorescent tube whose optical source is LED. Traditional fluorescent tube is also called fluorescence whose both ends have a directly heated cathode and the tube inside has little argon and lean mercury vapor. And there is fluorescent powder inside the tube. When the gas between the two directly heated cathodes electrifies, emitting ultraviolet, the fluorescent powder will emit visible light.

Compared with the small incandescent lamps and neon bulbs, the led downlight have following characteristics: the operating voltage is very low, sometimes only little; the operating current is very small that it can be lighting by a little of current. Besides that, the LED lights possess good properties for shock resistance and earthquake resistance, high reliability, long life circle and you can regulate the degree of the luminous emission by regulating the strength of working current. Due to all of these characteristics, Light-Emitting Diode is used as the source of light in some photoelectric control equipment and as a signal indicator in plenty of electric devices.

What's more, the LED of high efficiency is also energy conservation product which has high efficiency of driving power. And it is very important about the position of power supply installation in the whole structure of the LED lights. With the high efficiency of the power supply, it can be beneficial to set back the light decline of the LED downlights.

All in all, LED technology brings so much convenience to us all. It can not only used for general lighting, but also can be applied in a lot of fields such as office building, shopping mall, restaurant, school, house and factory,etc.
