Bright showing from long-life LEDs
The Luxeon III is a new high-power 100kh-life LED that generates typical light output of 65 and 80 lumen from a single emitter at 700 and 1000mA operation, respectively.
The latest LED automotive lighting firsts for production passenger cars made possible by Luxeon LED technology include: the first power LED backup lamps, featured in both the 2006 Cadillac DTS (two Luxeon I emitters in each of two lamps) and the 2006 Jaguar XK (three Luxeon I emitters in a single lamp); the first power LED stop-tail lamp in the U.S.
market, incorporating two Luxeon I LEDs on the 2006 Lexus IS; the first power LED rear fog lamp, built with three Luxeon I emitters for the 2006 Jaguar XK; the first power LED front turn signal, consisting of a six-Luxeon I LED assembly on the 2006 Porsche Turbo; and the first single, power-LED mirror side-turn lamp, featured on both side mirrors of the 2006 Audi Q7 using a Luxeon I LED.
In each case except the mirror side-turn lamp, the Luxeon LED assembly replaces a conventional 21 Watt incandescent bulb.

High-power LEDs claim new standards
Lumileds Lighting is expanding its Luxeon high-power LED family with new emitters claimed to set industry-wide performance standards.
LED emitters need no heatsink up to 40C
LED emitters will yield more usable light per dollar by reducing heatsink requirements and permitting higher current operation for more applications and opening new design possibilities.
In the mirror side-turn lamp, each Luxeon I LED replaces what is usually an array of low-power LEDs.
Audi has also expanded its use of Luxeon technology in daytime running lamps (DRLs) that began with the 2004 Audi A8W12.
In that vehicle, five Luxeon I LEDs created a distinctive cloverleaf-shaped DRL within the headlamp assembly, marking the first appearance of an LED DRL in a production vehicle.
This year, Audi expanded their DRL program and incorporated Luxeon LEDs in the DRL of the 2006 Audi S6.
Although conventional LEDs are commonly used for a variety of exterior automotive lighting applications, Luxeon power LEDs can reduce the number of emitters required from as many as 18 to just one or two.
They also meet or exceed stringent automotive standards; offer significant power savings compared to incandescent bulbs; and will last for the life of the vehicle.
"Given the design cycles for automotive lighting projects, we expect to see a significant number of vehicles utilising Luxeon LEDs hit the road over the next few years," said Jason Posselt, Marketing Director for Automotive Products.
"The Luxeon based systems are approaching cost parity with other systems, introduce new design opportunities for stylists, and minimise the weight and dimensions of each lighting solution, thereby further reducing power usage and costs".
The recently released Luxeon K2 and the company's continued development of power LED solutions for the automotive industry will drive adoption of the power-saving, environmentally friendly technology into headlamps and other applications that until now have required the light output of conventional bulbs.
The company recently announced its breakthrough development of LEDs that surpass the luminance of the halogen bulb commonly used in vehicle headlamps.
