Led Lighting applications in the expanding, while the use of LED automotive industry gradually coming into view, although its size is not as general lighting market as big, but still has a large market attractive, high-brightness LED in Application of the automotive industry not only business opportunities LED manufacturers, but also to the automotive manufacturing industry has brought some bright spots.
Investment Advisor in Senior Fellow in China, He pointed out that although high-brightness LED applications in the automotive industry is more innovative, but the favorable characteristics of the opportunities really are more alarming. Due to the high brightness LED with shock and vibration, thermal cycling and the advantages of long life, which greatly improve the performance of automotive lighting, it will gradually emerge in the automotive industry.
Although high-brightness LED use in the automotive industry to produce powerful effects, but current use of the many problems still exist, reliability and service life are the first issues to consider, followed by efficiency issues, again, the response rate in the brake lights and the use of direction indicators also need to stand on the test. Of course, the question of its direction is a key consideration, because the characteristics of light through the surface may not be suitable for automotive interior lighting for all areas.
According to the Investment Adviser's "2010-2015 China's semiconductor lighting (LED) industry, investment analysis and forecast report" shows that the use of LED automotive lighting has many complex criteria, such as whether the voltage is 40 volts, 60 volts, 80 V or 100 V LED driver circuit must meet the stringent requirements of automotive EMC specifications, for through the efficient and inductive switching regulator drives the LED, a certain degree of difficulty meeting the above requirements, the use of it will increase costs.
Investment Advisor, research director Zhang Yan Lin pointed out that because auto production limited size of the far field of general lighting of large-scale effect, therefore, try to tap the automotive industry, LED's can make use of the scope of a LED in the automotive sector by the next target, not only the use of external functionality, including car lights, pedals, lights are all worthy of the area in addition, using the same car entertainment is a great easy, flat panel displays will further increase the use of LED in scale automotive applications.
