Osram forecasts electric vehicles to benefit most from new LED lighting
Hillsboro, N.H. - When the travel range of electric vehicles determines who makes it home to re-charge their batteries and who is stranded by the side of the road, every watt saved and every additional mile counts.
So suggests Jonathan Dunlap, an automotive lighting engineer and product marketing manager with OSRAM SYLVANIA, the world's leading manufacturer of automotive lighting, in reference to an SAE paper regarding LED and power consumption of exterior vehicle lighting. Though the paper was written in 2008, the trend is now taking hold, he says.
OSRAM believes that "micro-hybrids" or mild hybrids, which feature engine stop/start mechanisms to boost the efficiency of conventional vehicles, will benefit greatly from LED lighting by reducing power draw and battery drain, as well as increasing light output during low power mode and startups.
"Just like going from a 75 watt incandescent light bulb down to a 18 watt compact fluorescent has made a significant difference to reduce the nation's energy consumption in the home, so too can LED lighting make a difference in automobiles, especially once alternators and generators in the cars are right-sized for higher efficiency," says David Hulick, marketing director for Automotive Solid State Lighting for OSRAM SYLVANIA.
The benefits are most notable in electric vehicles, which rely completely on stored electricity from batteries. "An efficient LED headlamp system can extend vehicle range by nearly six miles (9.5 km). Even with conventional vehicles, a 28 watt LED system emits only 196 grams of carbon dioxide per 100 kilometers compared to 768 grams of carbon dioxide per 100 kilometers from conventional 110 watt H7 halogen bulbs. Whether the goal is reduced fuel consumption or reduced carbon emissions, LED lighting is the best technology available," said Hulick.
Most people are aware of this surge in electric vehicles, but few realize that their headlights may soon have no light bulb to speak of. "Automakers are considering LED systems for forward and other lighting needs as one of the measures to achieve energy savings," says Dunlap.
But not only will electric vehicles benefit. The race is on to reinvent the automobile to meet ambitious new fuel economy standards. Vehicles are or will be receiving a super high-efficiency makeover in the form of downsized turbocharged engines, hybrid powertrains, low-rolling resistance tires and more efficient lighting systems.
Dunlap points out that lighting changes will make a significant contribution to fuel efficiency and carbon emission reduction goals both in the U.S. and abroad.
Traditional halogen bulbs can draw 240 watts in high beam mode, whereas OSRAM's JOULE® LED lights draw only 56 watts. While this may seem small, with more than 240 million vehicles on the road driving millions of miles every year, the energy and fuel savings will be significant.
OSRAM's LED lights are already featured on popular cars such as the tail lamps on the Ford Mustang.
