LED Lighting to Reduce Vehicles Power Consumption 2009-01-0059

When LED appeared on the market, it was claimed that reduced power consumption was one of their stronger advantage.
Today we see that the major contributor for introducing LED technologies, in both rear and then front lighting, is rather style driven while other potential benefits such as improved performances, reliability and power consumption are usually considered at a lower rate by the market.
Nowadays, when we analyze the market motivations and the different questions from OEMs on LED lamps characteristics, we see that power consumption of each lighting function is becoming a recurrent question
The goal of this paper is to describe the real impacts of LED on vehicle consumption, based on the different functions and their mission profile. It will also compare existing solutions for the major contributors (DRL, Stop/Tail, Low Beam).
Moreover some of the latest optic solutions for low beam will be described, solutions which will combine style & efficiency, for SAE and ECE beam patterns
