Aug 15, 2017: LED has extended its reach to a number of lighting applications including automotive. LED automotive lighting is becoming popular with each passing day, and converting halogen to LED facilitates the automakers to enhance night time visibility, said Steve Lietaert, the president of Hella Corporate Center USA, while talking to Automotive News.
Lietaert also said that LED automotive lighting allows automakers to include exciting and original features into their cars, and at the same, saves tremendous amount of valuable energy.
Among the possible lighting advancements by LEDs: the capability to project navigation directions directly onto the roadway ahead, being capable to decrease glare for drivers of approaching cars, and even allowing cars alter light colors to help other drivers see better.
Lietaert believes that the replacement of halogen headlamps to LEDs is in progress, and is set to quickly grow at the end of this decade. One of the main reasons for this will be vehicle power. A characteristic halogen headlight utilizes 55 watts of power to create 350 lumens of light, whereas LED headlight uses 17 watts to create 600 lumens of light, said Lietaert.
Furthermore, he predicted that the halogen lighting will go away by 2020, mainly from the point of view that no vehicle leading engineer will permit you to waste 55 watts on a headlamp. It will be an immense struggle for power in a vehicle. As more electrification is put in a vehicle, the more the need to decrease the load, added Lietaert.
Furthermore, he also added that LEDs already have a good impact inside the car. Automakers now use LED interior lights to permit customers to alter interior lighting colors according to their wish. Additionally, work is rolling that would utilize interior lighting to boost audible warnings to aware drivers of possible dangers.
The safety aspect
LED-based headlights have immense potential to enhance vehicle safety by improving driver visibility during the night, according to Lietaert. Banks of LEDs like the 84-LED stack utilized in the recent Mercedes Benz E-class headlights can be separately turned off and on to get rid of glare shining into the eyes of approaching drivers, added Lietaert.
He also said that LED-based headlamp has the ability to amplify illumination in areas that would otherwise be dark under conventional lighting systems. LEDs are very durable as compared to traditional source of lights. The light source strives to outlast the means of transport, added Lietaert.
