With the introduction of the i8 later this year, BMW is also going to introduce their new laser light technology as an optional upgrade to their upcoming hybrid sports car. The laser boost feature ensures a high beam range of up to 600 metres which is double to what is offered by a modern LED high beam. Besides increasing the range, the laser technology can also increase energy efficiency by 30%.
BMW Laser Light illuminates the road ahead with a significantly higher light intensity without heating up the surrounding area. Laser diodes are ten times smaller than conventional light diodes. They help to save not only available installation space inside the headlamp, but also weight. The size of the reflector surface can be reduced by a factor of up to ten vs. LED light. The height of the reflector has now been reduced from the previous 9 cm to less than 3 cm.
The light of a laser headlamp is extremely bright, similar to daylight, which is perceived by the human eye as pleasant. Several high-performance diodes emit a strongly bundled beam via special lenses onto a fluorescent phosphorus substance inside the headlamp.This substance transforms the beam into an exceptionally bright white light that is ten times more intensive than conventional light sources. Due to their highly intensive and virtually ideal beam properties, laser diodes render the overall system even more efficient. In conjunction with the camera-aided digital highbeam assistant, dazzling of oncoming traffic or vehicles ahead is reliably eliminated.
