The BMW M4 Concept Iconic Lights model 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 (organic light-emitting diodes), which produce light from
wafer-thin layers of organic material.
A special optical system converts the coherent monochromatic blue
laser light into a bright white light, 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, over twice that of conventional headlights, increasing
safety in the dark. The camera-based BMW Selective Beam system prevents
oncoming or preceding vehicles being dazzled.
Integration with the navigation system allows the
proactive Adaptive Headlight control system to illuminate corners even before
the steering wheel is turned. With the Night Vision system’s Dynamic Light Spot
function, people and animals can be detected from a distance of up to 100
metres in pitch-dark conditions by infrared camera, and spotlighted by the
laser-based Dynamic Light Spot.
Organic light-emitting diodes – OLEDs – are
innovative, efficient, sustainable light sources that form the basis for the
BMW Organic Light system. OLEDs have low power consumption which further reduce
vehicle emissions. Another sustainable feature of this technology is that no
expensive rare earth metals are required in the production process. Unlike
ordinary LEDs, OLEDs produce light uniformly over their entire surface.
In the past, rigorous legal requirements
regulating the brightness of vehicle lighting have limited the number of
lighting functions that were possible to implement with OLED technology. On the
BMW M4 Concept Iconic Lights model, BMW Organic Light is used in the tail
lights and rear direction indicators, making it possible to create different
rear lighting effects in different driving modes.
The BMW M4 Concept Iconic Lights model presents a
new interpretation of the twin circular headlight theme. The headlights feature
laser technology which is attractively highlighted by fine blue LED strips when
the vehicle is on the move. Thanks to the new laser technology it was also
possible to give the headlights a flat and sharply sculpted design.
BMW first presented a rear light cluster with OLED
elements on the BMW Vision Future Luxury concept model, which made its world debut
in Beijing in April 2014. BMW M4 Concept Iconic Lights displays its own version
of this design. Its M-style OLED rear light cluster marks a new evolution of
the BMW L-shaped lighting design which, making it possible to create a new,
more three-dimensional and at the same time very sharply defined appearance.
