A BMW M4 to light up your life


AT THE 2015 Consumer Electronics Show (CES) in Las Vegas, BMW is showing off its latest Laserlight technology, which it claims is now able to offer its long beam range of up to 600 metres in combination with the BMW Selective Beam function.

The technology is being displayed in a BMW M4 Concept Iconic Lights model which features a new interpretation of the typical BMW twin round headlights. The laser technology can be identified by the fine blue strips inside the lights.

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.

Integration of the Laserlight with the navigation system, for example, allows the proactive Adaptive Headlight control system to illuminate corners even before the steering wheel is turned. Laserlight also adds a new dimension to the Night Vision system's Dynamic Light Spot function. In dark conditions, people and animals can be detected from a distance of up to 100 metres, by infrared camera, and "spotlighted" by the laser-based Dynamic Light Spot. This is a longer range than that of any other system.

Normally the L-shape is wide and uniformly illuminated, in Sport mode a different-shaped light pattern can be used by activating only some of the OLED segments. The rear light then appears as a narrow, focused and sharply defined "strip" of light.
