Abstract

Automotive headlamps are critical in preventing traffic and pedestrian accidents at night. This article discusses how headlamping is being revolutionized by new lighting technologies. Several automobile manufacturers have already installed adaptive front lighting (AFL) systems with high-beam assist features that automatically adjust headlamps between low and high beam according to the level of oncoming traffic. The next generation of technology will combine satellite navigation with AFL to adjust headlamps based on data from digital maps. Systems would control the direction of vehicle lights both horizontally and vertically for better lighting on road curves, inclines and declines. Current AFL systems cost between $3000 and $5000, making price a hindrance to widespread AFL adoption. Another challenge is making these technologies compatible with light-emitting diode, which has the potential to be more energy-efficient than Xenon, but cannot yet provide the same level of brightness and visibility. Concerns have also been raised on whether these systems allow drivers to adequately detect pedestrians and bicyclists. To overcome this challenge, one manufacturer is using a advanced thermal imaging system that can alert drivers of pedestrians and cyclists in the road ahead.
