Headlight manufacturing companies will set a new trend next year by switching headlights to LED lights. In fact, these companies are currently making very small LEDs for car headlights of the future.
LED stands for light-emitting diode and it is a semi conducting device emitting incoherent narrow-spectrum light when electrically biased in the frontward path. This light formation is categorized as electroluminescence and that light that is emitted by LEDs is actually dependent on what composition and condition the semi-conducting material are in, similar to ultraviolet and infrared.
Beginning in the 1970s, LEDs were first used in wristwatches. The use of them as lights did not occur until much more recently. LEDs are currently being used in traffic lights and in car taillights, and when car manufacturers begin mass-producing cars with LEDs as headlights it will not only make the headlights brighter but also help light up roads at night.
When car companies start using LEDs as a normal form of headlight it will truly help illuminate the streets at night. LED lights not only look sleek and sophisticated but they are also last a long time. Audi began using LEDs as headlights with their A8 model, and eventually used LEDs as headlights in their S6 and S8 models as well as the A8. LEDs are also be used in Audi's newly released R8 sports car, which is truly one of the classiest and slickest cars on the road.
"We are working on LED headlights. We hope to have them after 2007," said Audi spokesperson Jeff Kuhlman. "For now, it's so expensive it'll be for niche models," added Michael Hamm, Head of the Innovative Lighting Unit at Automotive Lighting in Reutlingen, Germany. Hamm's job consists of working with Audi on LED headlights.
LEDs, unfortunately, are more expensive than normal lights and can cost up to eight-times the cost of high-intensity HID lights. HID lights, icy blue in color, are not as good as LEDs as they produce high amounts of glare and can cost as much as $1,000 to replace, according to Fred Snow, an executive at Hella, an automotive lighting company. Fred worked at a display at the Specialty Equipment Market Association.
Many other cars are beginning to follow the trend of using LEDs. Cadillac will be putting LEDs in their Escalades, and Lexus LS and Lincoln Navigators will also be using LEDs as headlights in the near future. More and more car companies will continue to follow this trend as the years go by due to all of the positive aspects of using LEDs as headlights.
