Recently in Las Vegas ended Consumer Electronics Show CES. Reporters vied talked about fold into a tube OLED-TV prototype LG and Chinese phone with a folding screen in half, but missed a revolutionary new product.
The inventor of the blue LED Shuji Nakamura, won in 2014 for his invention of the Nobel Prize, and his company SLD Laser provided first industrial samples LaserLight laser light sources.
The principle of operation is similar to the white LED - light blue laser is converted to white using the phosphor.
It is alleged that the laser light source is a hundred times brighter than conventional LED. He gives 500 lumens per square millimeter. Unfortunately, the developers do not say anything about the effectiveness, but claiming low power consumption and long service life.
According to the company, the headlights with laser light sources will be installed at premium automobiles this year. LaserLight can be used in a flashlight (the visibility of the beam reaches 1 km), as well as unmanned aerial vehicles, devices for search and rescue operations.
The company's website has several videos of LaserLight trials. Here is one of them

One of the advantages LaserLight called very narrow illumination angle <2 °. It's good for lamps and spotlights, and bad for conventional lighting, but a narrow beam can be dissipated.
It is possible that Shuji Nakamura, a revolution in lighting (thanks to his invention the whole world is now illuminated LEDs), will make a second revolution and after a few years, even in ordinary homes will use laser lighting.
