BMW engineers are currently working on the introduction of laser light for the BMW 6 Series. The company will use full LED lamps for the series which will also include new developments such as the ‘anti-dazzle high-beam assistant’, a statement said.

Laser light could then facilitate entirely new light functions for more safety and comfort and at the same time contribute significantly through its higher degree of efficiency towards a saving in energy and fuel respectively, the statement from the company said.

By definition, laser lighting is radically different from sunlight, and from the various types of artificial lighting in common use today. It is monochromatic, the light waves all have the same length, and is also known as a ‘coherent’ light source, meaning that its waves have a constant phase difference.

As a result, laser lighting can produce a near-parallel beam with an intensity that is a thousand times greater than that of conventional LEDs. In vehicle headlights, these characteristics can be used to implement entirely new functions. The high inherent efficiency of laser lighting also means that laser headlights have less than half the energy consumption of LED headlights, thus saving fuel, the statement said.

As the light is not emitted directly, the intensity of it poses no possible risks to humans, animals or wildlife when used in car lighting. The light is first converted into a form that is suitable for use in road traffic, making it very bright and white but also consumes less energy and is pleasing to the eye.

Completely safe laser lighting technology is already in use in a variety of consumer products, though in many cases this is a product feature that goes unnoticed by the customer, it said.

A further advantage of laser lighting technology, and one which the BMW engineers intend to use to full effect, is its high inherent efficiency.

Safety is a key consideration in the development of laser lighting for use in passenger cars. Before the light from the tiny laser diodes is emitted onto the road, the originally bluish laser light beam is converted by means of a fluorescent phosphor material inside the headlight into a pure white light which is pleasant to the eye, it said. – TradeArabia News Service
