This time LASERS will only ZAP away darkness. Yes, LASER light is powerful, thousand times more powerful than LEDs. That's because - a Laser cell generates 170 Lumens of brightness compared to an LED cell, and on top of that it is much, much smaller. You can pack a 100 LASER cells in the space occupied by a single LED cell. So what you get is intense, bright well behaved light. Well behaved - because Laser light doesn’t radiate outwards. Remember Star Wars? LASER light shoots straight, it doesn’t spread out as the beams travel parallel to each other. Which means it will be possible to create very specific light patterns, which will be a big help for different speeds, oncoming traffic and cornering lights.
Now you won’t be able to use these lights as weapons... I know what a shame. Imagine pressing the high beam switch to “blind” that oncoming truck. Anyway, evil thoughts aside, it isn't possible because it isn't raw laser light that will shoot out of the head lamps. A fluorescent phosphor material will convert the bluish laser light into a bright white light, which will be safe for human or animal eyes.
Other than improved safety thanks to better visibility Laser will also improve fuel efficiency as it consumes even lesser energy than LEDs. Also, LASER cells will allow designers greater freedom with packaging the front end, so how cars look will also change. Although BMW insist that the "eyes" won’t be made smaller, how that space is used will change. And who knows, maybe laser light will replace LEDs on the inside of cars too.
So let’s see when LASER tech gets to us. BMW's says it is a "few years" away.
