Advantages of LED car lighting applications

In spite of various problems, such like expensive costs, heat dissipation problems, technical difficulties, automotive manufacturers still strived to introduce LED car lighting applications. The main reason is this new lighting source can unprecedentedly make vehicle lighting design more flexible. It is even possible for consumers to customize their automotive style. In addition, the light efficiency of LED lights has already been able to match with HID lamps. Therefore, it is highly hopeful that LED can surpass other existing lighting technology and dominate car lighting market.

 

In spite of various problems, such like expensive costs, heat dissipation problems, technical difficulties, automotive manufacturers still strived to introduce LED car lighting applications.

 

According to the product manager of Cadillac Escalade Platinum, the light distribution spectrum of LED is closed to natural light, making the reflecting efficiency from objects (such as road traffic instruction signage / line) be much higher than other lighting sources. Thus drivers can observe from a far distance and we take an early respond.

 

The temperature color of LED car lighting applications is around 5500K-6000K, whiter than other car lamps (HIP lamps that send out light blue rays have temperature colors around 4000K and halogen lamps send out yellow rays have temperature colors around 3000K). Therefore, in the optical design of HID lamps, scientists usually shifted the blue rays in the spectrum to the edge of emission spot, which places drivers rarely took notice of, in order to reduce the uncomfortable interference caused by colored rays.

 

But for oncoming drivers, still will be interfered by Blue-rays in the marginal area, causing dazzling and consequently increasing the risk of accidents. In the anti-glare aspect, high-power LED lamps (large LED lamps) have big advantages: not only provide sufficient comfort for the owner, but also keep nearby drivers from visual interference. Since Toyota Lexus applied different lighting sources on dipped headlights (LED lighting technology) and high beam lights (halogen lighting technology), owners of LS600h may interfered by color difference during the switching.

 

In a word, according to Mr. Asif Anwar from the marketing research and consulting department of Strategy Analytics: although LED car lighting applications are in the very early stage of development, the market has huge potentials. It is expected that, by 2012, the market of LED car lamps will reach up to 80 million dollars. LED will become the new darling of the automotive lighting industry due to its advancing in security, reliability, energy efficiency and ease of aesthetic design.

The feasibility and advancement of LED car lighting applications

As the 4th generation lighting source, LED car lighting applications are feasible and advanced than other traditional car lights. In this article, we will discuss about the current situation of LED lights applied in automobile industry.

 

As the 4th generation lighting source, LED car lighting applications are feasible and advanced than other traditional car lights.

 

Vehicle lighting industry was emerged in the early of 20 centuries. Kerosene lamps and acetylene lamps were two oldest lamps that used in cars. After the invention of electricity in 1910, incandescent lamps, halogen lamps and high-intensity discharge lamps (HID) became the main vehicle lighting products in succession. Since 1985, LED lighting technology started to emerge in a verity of vehicle lighting applications and meanwhile the LED used Adaptive Front Lighting System (AFS).

 

Currently, LED has been made used of by many vehicle manufacturers: BWM, Ford, Honda, Toyota, Mercedes-Benz, Audi, etc.. In order to improve the overall competitiveness, they have launched new cars with applications of vehicle LED lights.

 

LED car lighting applications have many advantages: 1) longer service life, better anti-vibration capability. In theory, LED can maintain a normal work for more than 50,000 hours, the practical working time is no less than 20,000 hours (still longer than the that of traditional halogen bulbs, which can continue to work about 150 to 500 hours). That means, LED lights have longer service lives even than cars themselves. Besides, there are no moveable compartments within the entire structure of LED car lighting applications, giving them a much better anti-vibration capability. 2) Environmental friendly. LED can obtain sufficient luminous flux under low voltage and low current, consuming only 10%-20% energy of other traditional lamps, no health-hazard mercury, there is no environmental pollution during production and recycling. 3) Fast respond. Unlike incandescent lamps, the respond time of LED lamps has reached tens of nanoseconds. Thus LEDs are more competent in vehicle tail lighting applications, which can speed up the respond of the follow-up driver. 4) Small size. Compact LED can diversify the automotive-style design, and consequently make the model more stylish. Compared with traditional lamps, the installation depth of LED signal lighting system can decline by 80mm, which is rather significant for the layouts of internal compartments.

 

At present, the automotive industry is still the pillar industry in the global economy, and in the phase of rapid development. There is no doubt that all this will drive the development of vehicle compartments, including LED car lighting applications.
