LED lamp refers to the use of LED (light emitting diode) as light source lamp. Because LED has the advantages of high brightness, color rich variety, low power consumption, long service life, LED has been widely used in the automotive field. LED lamp profile LED lamp production requirements LED lights will become the future market mainstream characteristic of vehicle lighting LED lamp development and classification of domestic LED lights the bottleneck of the development of domestic LED lamp prospect Brief
introduction of LED lamp
Now the car lights had incandescent lamp, halogen lamp, xenon lamp etc.. In addition to headlamps, other lamps such as lights, litter lights, car lights is the use of incandescent lamp etc.. But in recent years also popular at LED as indicating lamp, such as brake indicator light, turning indication lamp etc. Why the instead of incandescent lamps with LED? The outer cover can be made with the PC pipe, maximal temperature up to 135 degrees. Greatly improve the light transmission effect, enhance the impact resistance!! Resistance to weak acid and neutral oil. Effective period of 20 years. The original advantages of LED are significant compared with incandescent lamps,
First is the long life, generally up to tens of thousands hours, even one hundred thousand hours. Some people think that if the car lighting the use of LED in future, the whole car use period without changing the lamp.
Secondly is very energy-efficient, more than half of the same brightness of the incandescent lamp energy saving at least.
Thirdly is the high quality light, basically no radiation, which belongs to the “green light”. Fourthly is a LED has the advantages of simple structure, the internal support structure, seal around with epoxy resin transparent, good seismic performance.
Fifthly is not need hot start time, lighting fast response (nanosecond), suitable for fast moving objects using.
Sixth is applicable at a voltage of 6-12 volts, can be applied in automobile.
Seventh is the LED occupancy volume is small, the designer can transform lighting mode freely, auto modeling diversification. Automobile manufacturers favor LED, is completely determined by the advantages of the LED. This is LED lamp production requirementsFirst according to the standard optical design need of light shape requirements, including the LED brightness, distribution of light beam, design of beam angle。 Although LED can save energy and has the advantages of small size, but the beam angle of narrow and LED heat treatment is higher requirements, so LED is used as the lamp on the processing of the need to pay particular attention to the uniform light. Another is heat treatment for LED, if the heat do not, will not only affect the life of LED, but also lead to LED appears in the light emitting device attenuation, based on two restrictions, LED lamp has not been very good development, only a few top grade car assembly. Secondly LED quality control and check of light production coordination, it is relatively simple when compared to the headlights, lights require. But the main thing is to solve the problem of uniform light LED, namely, how to make uniform distribution when output of the LED light, and good heat dissipation problem solving of LED. LED lamp is dong after need to do some performance testing and 3C certification,LED lamp will become the market mainstream of vehicle lighting in future.
With the continuous development and evolution of LED technology, its applications in the automotive industry have been more widespread. However, the current LED companies in the lights, backlight, lighting and other three major application market is still in the development stage, certification, lean on demand that this year industrial growth contribution is not big, but along with the industrialization speed, the next LED companies in the lights, backlight, lighting and other three areas have a large number of applications.
