The laser diode - the future of modern lighting

Completed in Las Vegas Consumer Electronics Show CES marked not only a demonstration of the roll-up TV and folding screen of the phone, but also a demonstration, I'm not afraid of the word, the revolutionary new items.

received Nobel Prize in 2014 for the creation of a blue LED Shuji Nakamura together with his company SLD Laser We presented the first serial instances of laser light sources LaserLight.

new design algorithm is similar to the principle of the white LED that is blue laser light is transformed into normal white due to phosphor. And the converted white light is incoherent, or absolutely safe for the human eye.

According to the developers, they were able to increase the brightness of the laser light source, compared to the conventional LED, up to 100 times. When this diode is capable of producing up to 500 lm per square millimeter. This laser diode (also according to developers) capable of up to 10,000 hours.

In this case the beam angle is <2 degrees at a rate of 35 mm lens. A ready-made SMD the product has more than modest size.

Starting as early as this year, such laser diodes will be used as a beam on some vehicles, the premium segment. In addition, they will also be used in lighting optics miniature aerial vehicles (drones) and portable lanterns.

Of course, single-minded focus of incoherent white light for home lighting is a greater disadvantage than advantage. But it is likely that Shuji Nakamura and his team will solve the problem of dispersion, and after a couple of three years in each house will burn longer bulb, which will be used laser diodes, as they are now burning conventional LED.

In this video you can see the official test LaserLight.

That's all I wanted to tell you about a new stage in the development of LED lighting. If the article is to provide you with interesting and useful, you will appreciate it Like. Thank you for your attention!
