BMW M4 Concept – Iconic Lights
At the Consumer Electronics Show (CES ) 2015 in Las Vegas, BMW is providing further evidence that it is a world leader in the development of Laserlight. Having already supplied its first models with Laserlight to customers, it is now presenting further laser functions for vehicles of the future. Laserlight is now able to offer its impressively long beam range of up to 600 metres in combination with the BMW Selective Beam function (anti-dazzle High-Beam Assistant). At CES, BMW is unveiling ways in which Laserlight, extensively integrated with assistance systems and vehicle sensors, can be used to implement new intelligent lighting functions for enhanced safety and comfort. For example, it can work with the navigation system to illuminate corners well in advance, while a laser-based Dynamic Light Spot can provide early warning of people or animals at night from a distance of up to 100 metres.
BMW Laserlight sets new standards in terms of beam range and brightness. Inside the laser headlights, the “coherent” monochromatic blue laser light is converted into harmless white light. A special optical system directs the rays from the high-performance diodes onto a phosphor plate inside the light, which converts the beam into a very bright white light that is similar to natural daylight and pleasant to the eye. Despite consuming 30 percent less energy, the parallel light beam is ten times more intense than that produced by halogen, xenon or LED light sources. BMW Laserlight also has a beam range of up to 600 metres, more than twice that of conventional headlights, for increased safety in the dark. The camera-based BMW Selective Beam system, which is controlled by dynamic actuators, prevents oncoming or preceding vehicles being dazzled and allows the laser high beam to be left on at all times.
