A consensus on energy saving LED shines a light green

May 1, 2011 - PRLog -- A consensus on energy saving LED shines green light recently, Wuhan National Laboratory for Optoelectronics and Energy Engineering, Huazhong University of Science and Technology Cooperation, developed an international leader in LED automotive lighting technology. LED is a theory made of the use of electronic light-emitting semiconductor devices, which can be directly converted into a variable optical power with high luminous efficiency, long life, low power consumption, small size and other characteristics, known as the 21st century "car Green light source. "

According to Associate Professor of Huazhong University of Science introduced Luo XB, LED, also known as light emitting diodes, the use of solid semiconductor chip as luminescent materials. When coupled with a positive voltage across the semiconductor carrier in place complex, will be able to release excess energy photon emission caused by visible light. LED production can be divided into upper, middle and lower reaches. In recent years, foreign rapid development of LED technology and industry, Japan, the United States and some European companies, in the upper light-emitting material, that is, the chip manufacturing and middle reaches of the cutting, grading and other fields has become highly technical monopoly. Independence in terms of the Wuhan High-power LED light source technology to develop, so that part of our package in the downstream reaches of the world leading level on the LED light source and the promotion of a wide range of applications will have an important significance.

Currently, energy saving green products have become the mainstream auto industry, automotive lighting is no exception. Speaking from the manufacturing process, production of materials used in LED light source does not contain heavy metals, compared with other light emitting efficiency can be increased by 20% or more. LED lighting is not only a vehicle with both environmental protection and, more importantly, to ensure safety and reliability. LED life span is very long, the average time between failures of 10 million hours, considerably more than incandescent life of 3,000 hours to achieve the requirements. LED light sources are solid, solid package, and its Vibration resistance but also in other sources can not be compared. By the semiconductor light-emitting LED, light of only the nanosecond. Real vehicle in real trials, the same person in the case of 80 kilometers per hour started braking, watching led lantern than incandescent reaction speed, 4 to 5 meters ahead of schedule to achieve full braking. This highlights the rapid reaction capability used in the rear, you can greatly improve the safety of motorists.

According to the information, LED light source can be divided into vehicle interior and exterior LED lights LED lights two categories (led flashlights). LED is mainly used in car dashboard digital display backlight assembly of the light, the angle of the LED, color, brightness, voltage, current and other optical and electrical properties of consistency and higher reliability. LED lights outside the car is mainly used for brake lights, front turn lamps, rear turn lights, side turn signals, rear fog and reversing lamp and so on. From a security point of view, the current on the LED taillights are more applications, while the headlamps are relatively small.

Recently, European analysts predicted that by 2012 the market share of LED lamps will be increased dramatically. But experts stressed that it also depends on a wide range of LED light sources to promote primarily their own technical problems. One is the luminous flux to be further improved. Using LED as the light source, you must have a higher luminous efficiency. Second, the LED emitted light and natural light is still a certain gap. LED light is not emitted a continuous spectrum of white light emitted by the yellow light and blue light "blending" together, so its color is not high. This is also the constraints one of the main headlamp LED used. Third, the high cost of the LED light source of popularity. Currently, the assembly of LED lights is also limited as only Reiz, Crown, Cadillac, Sagitar, Rong Wei, high-end cars. Due to the continuous improvement of wafer technology, manufacturing costs are currently falling sharply, nearly three LED's prices have fallen by 50%, is moving in high efficiency, low-cost direction, which is the field of LED lighting to the overall promotion of car Provided favorable conditions. However, some industry insiders believe that when the LED's cost down to 90%, is when the true popularity. From: led bulb light
