Audi and BMW Race to Adopt Laser Lights

Las Vegas - Two German manufacturers , Audi and BMW are not only competing as a number 1 beside the world for premium car sales , as well as technology . Competition for most brand is immediately utilize laser technology for headlights or main .

In December last year , Audi announced , will use lasers to light future e - tron R18 for Le Mans endurance race world or alias WEC ( World Endurance Championship ) , DTM and GT Sport . Even last week , at the Consumer Electronics Show ( CES ) 2014 , Las Vegas , Audi re- introduce the laser light , this time mounted on the sports car coupe concept plug-in hybrid or PHEV latest .

BMW
Previously , in September 2013 - at the Frankfurt Auto Show - BMW menggumumkan will use laser technology as the main light sports car plug-in hybrid ( HEV ) which will be launched at the end of this year , the i8 ( as optional ) . A year earlier ( 2011) , BMW announced , has successfully developed the laser light .

The use of lasers as an illumination more interesting because it can make the car look more cool , both exterior and interior . Some lighting companies in China , in recent years , incentive to offer a variety of laser light for interior lighting that produce various forms of light in the form of images .

Lasers are now widely used in everyday human activities . One is a computer user , ie mouse or laser mouse . Also used for audio devices equipped with connectors ( input and output ) or optical S / PDIF ( Sony / Philips Digital Interface Format ) , stage lights and disco .

LED rival
The laser light LEDs is expected to be a rival to the maximum undeveloped until now because it was too expensive . According to experts Audi and BMW , the laser has several advantages compared to LEDs . One of them , the element or cell size smaller than the LED .

The diameter of the laser diode element is very small . For comparison - according to experts BMW - a cell surface area of the LED lights square military . While the laser light is only a few microns or one-hundredth of a cell LED lights . Aspect is exactly the main attraction experts utilize lasers as the main car wars . With the smaller size , the designer can make the car more aerodynamic face .

Another advantage , the density of the light produced is higher . If the LED light produces 100 lumens for each watt , lasers can reach 170 lumens . The length sorotannya reach 500 meters or 5 times the length of a football field .

To produce white light color unsightly eye ( no glare ) , the resulting beam laser diode , first converted by a phosphor fluorescent lamp in the main . This must be done because the original color of the laser light bluish .

Audi has also been announced , will utilize laser technology as car headlights racing Le Mans , R18 e - tron Quattro launched in April.

Especially for a car that is on display at CES , laser headlights are combined with LED . Therefore, each side there are two layers of light trapezoid-shaped . According to Audi , the LED light for close range ( low beam ) , while the laser for long distance ( high beam ) . Here is the video.
