Earlier on, it was reported that BMW was set to present a concept car featuring an advanced version of its Laserlight system at the 2015 Consumer Electronics Show in Las Vegas. Well, here it is – arriving in the form of the BMW M4 Concept Iconic Lights.

As far as concept vehicles go, this BMW M4 is quite the looker with its Cool White metallic paint scheme coupled to the company’s trademark halo running lights – this time in an alien shade of blue thanks to the fine blue strips housed inside the headlight assembly.

Moving on to the rear, the lamp clusters on the M4 are comprised of OLEDs (organic light-emitting diodes). Measuring just 1.4 mm thick, the OLEDs are featured in both the tail lamps and rear indicators assembly and are arranged to produce a three-dimensional effect.


The OLEDs themselves are said to consume far less energy than conventional lighting systems, effectively helping to reduce vehicle CO2 emissions. Apart from that, production of OLEDs require no rare earth metals, leading to lower costs. Unlike conventional LEDs, OLEDs produce light uniformly across the entire surface.

BMW’s laser lighting technology – first seen on its i8 electric sports car – takes another step forward on the M4. Said technology utilises an optical system that directs the rays from the “high-performance diodes onto a phosphor plate inside the light,” turning the monochromatic blue laser into harmless, bright white light.

Compared to conventional LED, xenon or halogen light sources, BMW’s laser lighting system consumers “30% less energy” and “has a beam range of up to 600 metres.” Coupled to BMW’s camera-based Selective Beam platform, the laser lights are, essentially, turned into always-on lights.

With the laser lighting system paired up to most of the car’s onboard electronics, such as the Adaptive Headlight and navigation system, it is able to illuminate corners as the car approaches said bend. In addition to that, BMW’s Night Vision system gets a boost in ability.

By being able to pinpoint objects, animals or people from a distance of up to 100 metres using an infrared camera, the laser-based Dynamic Light Spot will highlight said obstacle, further decreasing the chances of an accident. A “narrow clearance” feature ensures that the laser rays illuminate the entire road ahead.

The system calculates the width of vehicles in front before adjusting the beam clearance to ensure that the road and only the road ahead receives the full intensity of the laser rays. BMW claims additional benefit in terms of lighting design as such systems enable a wider range of light shapes to be employed on future models.
