LED Trend will surpass others in 2012 automotive world
With a vigorous campaign of energy and effort of saving suppress carbon dioxide emissions, LED lighting applications more attractive to car manufacturers. Especially for major lights. The reason, the electrical energy consumption only 19 watts for each lamp. For this reason, the lights and the car manufacturers now focus on developing full LED headlamps. Previously, still the combination with xenon.Tech light emitting diode (LED) - as long as it's just known as semiconductor components - in the near future are expected to master the lighting system on the car, both for exterior and interior.
LED properties
If given the power LED, semiconductor surface will glow. The resulting color depends on the difference in the valence and conductivity properties of semi-conductor materials digunakan.Contoh, for the LED with Aluminum Indium Gallium Phosphide (AlInGaP) produced gold color (amber). While the luminescence conversion process, the resulting white light. Blue diode combined with the converter material, blue and yellow, also will menghasikkan white light.
Energy efficient
"Compare with the halogen lamp takes 55 watts of energy or xenon, generally 35 watts," said Thomas Reiner, Director of Applications Osram, one of the famous car lamp manufacturers in the world. Even foreseen, with the continued development, the LED will only require 15 watts of energy for the headlamps.
Currently, the incentive to develop LED lighting manufacturer in terms of lighting and other parameters in order to replace the conventional light bulb or who are still using incandescent lamps, both in exterior and interior.
Meanwhile, Automotive Engineering International (AEI) reported, Osram Opto Semicondutors Inc.menjelang end of last year (2011) introduced a white LED light. Thus, the LED will be the main source of lighting for the automotive in the future.
"The ability to remove the LED heat better than conventional lighting, such as xenon," said Mike Godwin, Director of Visible LEDs Osram. Another advantage, do not produce ultraviolet (UV) or infrared radiation (IR).
The light given off is also cool. Precisely illuminate the object but not the heat raises. Therefore, the LED lights are ideal for sensitive objects. Due to the automotive lamp, lamp socket or the house did not become a serious problem such as halogen incandescent lamps today.
Growth
According to Strategies Unlimited, the agency analysis of the optical industry in the United States, the use of exterior LED lights for cars will grow very rapidly despite the current commonly used for the new daylight lamps (daylight) and the rear combination lamps. But for the front headlights, diperkirakan10 percent growth per year.
Meanwhile, Osram is also trying to continue to develop LEDs for lighting car interiors. Godwin added, with a size smaller LEDs and a longer lifespan, in the long term will dominate the segment interior lights.
Also expected, the instrument panel with LED lighting will dominate cars launched in 2015. Because the price of LED lights will be more expensive. In addition, with a special chip design, can be made of lights that can create a mood (mood) in the cabin. All of that certainly will make the LEDs more attractive, liked or sought after consumers.
"There are still a lot of creativity can be developed so that the lamp is more interesting. Among others making a congratulatory graphic format (welcome) and good-bye (farewell) in lieu of on-off functions, "Godwin unveil.
