LED Lamp-emitting diode is a solid-state Lamp source, when the LED plus forward voltage across the semiconductor minority carrier and the majority carrier recombination, release of excess energy will cause photon emission. Using different materials, can be made of different colors have Lamp-emitting diodes. As a new Lamp source, in recent years, major companies and research institutions on the LED Lamps in the ascendant, its Lamp efficiency can be greatly enhanced.
With the further research on LED, its luminous efficiency will be further improved and the cost will drop step by step. In the near future, LED will replace incandescent lamp or even fluorescent lamp and develop into a major Lamping source in the 21st century. trend.
The new Lamp source calls for a new electronic ballast, Philips Lamping Electronics in the development of new LED at the same time, in recent years in various major development centers around the world started the LED driver circuit research and development in this area has occupied the world's leading status.
In addition, led lamps, although not as bright as xenon or halogen incandescent, and three or four LED together, the Lamp produced by ordinary battery life is 10-20 times, which is widely used in the automotive industry, traffic Lamps , Display and other fields.
Compared to incandescent lamps, LEDs are less susceptible to damage, such as falling or impacting, which lasts up to 100,000 hours, compared to hundreds of hours for traditional incandescent bulbs. Based on these advantages, LEDs have been favored by cyclists and campers as they can buy 1-20 LEDs for just $ 10-100 and are easy to carry around.
We need special attention: the real potential of Lamp-emitting diodes is in the field of digital electronics applications. As a diode, it is designed to be closer to the design of a computer processor chip than an incandescent lamp invented by Thomas Edison in the 19th century. LEDs are especially suitable for opto-electronics because incandescent lamps consume a significant amount of energy to meet temperature requirements, while LEDs are brighter, faster, more efficient, more reliable, and more purely color targeted.
