BMW spotlights advanced lighting technologies in M4 model

At CES 2015 in Las Vegas, Nevada, USA, BMW has unveiled ways in which the company's Laserlight technology can be integrated with assistance systems and vehicle sensors to implement intelligent lighting functions for enhanced safety and comfort.

Laserlight technology, which is able to offer a long beam range of up to 600 metres in combination with the BMW Selective Beam function (anti-dazzle High-Beam Assistant), 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.

The BMW M4 Concept Iconic Lights model, with exterior paintwork in Cool White metallic, features a new interpretation of the typical BMW twin round headlights. On the move, the laser technology can be identified by the fine blue strips inside the lights. Meanwhile, the rear light clusters of the BMW M4 Concept Iconic Lights model are based on OLEDs, which produce light from wafer-thin semiconducting layers of organic material. For the first time, both the tail lights and rear direction indicators feature OLED technology. The illuminated surfaces are positioned to produce a three-dimensional effect. OLEDs also take up less room.

BMW's Laserlight technology claims to set 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 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.
