Audi A8 Ostar.jpgThe South Korean chaebol LG Electronics and Osram are squaring up to each other - in suits and coutersuits - over the issue of LED headlights...

At the heart of the dispute is Osram purportedly infringing LG-owned patents involving LED chips and packaging technologies, and this has dragged in BMW and Audi cars featuring the contested LED technology.
 
Engadget writes:
You see, once upon a time LG was late to the LED patent game, and was content to fork over the cash to Osram for use of its tech. Skip to now, and the electronics giant's claiming it can get its lighting goods elsewhere, picking from a plethora of relevant IP-holding companies and combining that with its own patents.
Hella LuminatorTwo years ago, LED headlamps were in demand at motor shows, but xenon high-intensity discharge (HID) lights were brighter, and 99.9% of car buyers still got good old-fashioned halogen bulbs.

Now LED headlamp technology has matured and caught up, although, thanks to banking crisis, almost everyone still gets halogen bulbs, writes Steve Bush.

"There is not a big difference on the street between xenon and LED. LEDs have the same performance as a good xenon system, not just a low-end xenon system," Dr Wolfgang Pohlmann of German automotive lighting firm Hella told Electronics Weekly.

So why are car makers still using HID in their top models, despite their limited lifespan and the need for high-voltage inverters?

Bentley 2011 Mulsanne LED headlamp.JPGBuckingham-based Wipac has designed the LED headlamp in Bentley's 2011 Mulsanne, writes Steve Bush. The light is not all all-LED. Instead, eight power LEDs boost main beam mode from twin bi-xenon projectors.

The firm, now owned by LED lens maker Carclo, made its first vehicle light in the UK in 1948.

Its first solid-state car light was a 48-LED high-mounted stop lamp for Cadillac, way back in 1995, followed by one of the first multi-function LED tail lamps, for the Porsche Carrera GT in 2001.

Oxley Developments has been selected to supply a dual-mode LED lighting system for the Foxhound British army patrol vehicle, writes Steve Bush.

Foxhound is the British Army name for Ocelot, the Light Protected Patrol Vehicle (LPPV) designed and developed by Force Protection Europe.

Force Protection Europe has won a contract to supply 200 of the British-designed vehicles to the Ministry of Defence.

SignalSureLumileds has introduced an LED specifically for car indicators, writes Steve Bush.

Called SignalSure, the LEDs are AEC-Q101 qualified and meet Japanese and SAE/ECE requirements.

"Reliability and confidence in a surface mount signalling product has been our design objective from the start," said Paul Martin, director for automotive LEDs.
Lumileds LUXEON Altilon.jpgLumileds has announced a four die LED for automotive headlights, writes our Technology Editor Steve Bush.

Based on the firm's 'thin film flip chip' die and dubbed Altilon, Lumileds is claiming up to 850 lm and 60 million cd/m2 at 1A.

You can read a PDF on the LUXEON Altilon.
