Accelerate the future development and application analysis of LED lighting in technology research

After the LED car headlights have undergone the development stage of technical verification and concept car demonstration in recent years, they have finally ushered in the promising prospects for mass production cars. There are three landmark events: Toyota's Lexus LS600h is the world's first The use of LED front light source of the listed car, but it only applies the LED in the low beam, the remote light source is still halogen. The Audi R8 features full LED headlamps, while the LED used in automotive lighting is provided by Lumileds and Osram. The Cadillac Platinum Escadael Platinum sports car is the first multi-purpose sports car with LED headlamps.

Obstacles that prevent LED light sources from quickly opening up the automotive market Do the landmark milestones mean that LED headlamps will immediately become an innovative technology that dominates the automotive lighting industry? According to experts predict: Maybe not. Because even if the cost of LEDs can continue to decline at the rate foreseen by Moore's Law, it will take many years to achieve the same price as HID (High Intensity Discharge) deuterium lamp; and the LED family's cost will be reduced to that of halogens. If the lights are equal, you will need to go through a longer period of time.

According to Fischer, president of Hella, the size of automotive LEDs currently represents only a small percentage of the market share of light sources, so it is in favor of high-volume models (such as the GM/Chevrolet Malibu model). The matching supply is of great interest. However, LED needs to overcome a series of technical and cost problems to achieve the level of supply as large quantities as Malibu models, and at least a decade away.

Visteon pointed out that the LED's pace of entering the market is indeed slower than originally expected. We predicted in 2004 that LED lights would soon be injected into the city and HID would be eliminated. Obviously, the current situation is not the same, although it is always expected that LED technology can evolve faster than reality. It seems that the high cost is not the only factor that hinders the LED market. There are still challenges in terms of technical performance that need to be overcome. For example, for a single light source, the LED's light intensity is still insufficient. A single point is not bright enough to achieve the following wishful calculations: Reducing the number of LED light sources that make up a combination of luminaires will help to reduce the footprint of automotive luminaires and allow for flexible placement, simplifying the wiring and installation of lighting systems and reducing production costs.
