Meet the Future of Automotive Lighting: Laser Car Lights

LED headlights are only now becoming used regularly as manufacturer’s parts on vehicles. While most makers are now just starting to offer LED car lights as optional features, the most innovative automakers are already looking beyond LED lights to the next big breakthrough in automotive lighting–laser lights!

Laser Car Lights Are Real!

It may sound like something out of science fiction, but laser car lights are very real. Instead of conventional car bulbs, laser head lamps generate blue light with powerful laser diodes that are one-hundredth of the size of the emitters used in LED lights for cars. The light generated by the laser diode is passed through a phosphor converter that transforms the blue illumination into very bright white light. Special safety controls are built into the car lights to keep heat levels to a minimum, so the laser headlights won’t cut through metal like a laser in a sci-fi film.

Benefits of Laser Lights Compared to Conventional Car Bulbs

When compared to xenon car bulbs and LED headlights, laser car lights have a number of distinct advantages. They are:

Much Brighter. The white light generated by a laser headlight is 1000 times brighter than LED headlights.

More Efficient. It requires half as much power to operate a laser diode as it does an LED car bulb.

Much Smaller in Size. The tiny size of laser diodes allows cars to be lighter and gives automakers more room to add accent lights and other stylish features to the front ends of vehicles.

Customizable. Manufacturers can add all types of auto lighting technologies, like automatic dimming to laser lights, making car lights safer and more effective.

Who’s Making Laser Car Lights?

BMW unveiled the first-ever laser car lights design in 2011 and included them in the design of the BMW i8. Audi also featured laser headlights on the 2015 Audi R8 LMX, but the auto lighting was not approved for use on U.S. roads. The U.S. National Highway Transportation Safety Administration has a reputation for being resistant to adopting new automotive lighting technologies, so American drivers will likely have to wait a longer time than Europeans to see laser car lights up close and personal.
