how luminescence can give us such as solar LED lights

A team of German scientists have come up with new luminescent materials for LED lamps. Phosphorus improve energy efficiency and create artificial light is almost as natural as the sun.

Wolfgang Schnick knows a thing or two about the quality of light. Not only has the German chemist examined the luminescent material since 2001 - but the shopping expedition with his wife has taught him first hand the difference between a good and bad light.

You may have experienced it as well. The lights in the store could be so distorted that blue dress can appear black.


  has developed a new luminophore - a chemical compound used in the luminescence. change the color of the light emitted by the LED (light emitting diodes) in such a way that they believe has "the potential to revolutionize the LED market."

Mixing bright colors

Since incandescent lamps were ordered from the EU market in 2012, LED lighting has been endorsed as the best alternative.

They are popular because they do not like energy-saving light, LED light up instantly, without the heating phase, and they contain virtually no toxic materials.

The problem is the usual LEDs emit only one color. But that's not how we want to experience light in everyday situations.

When we read a book on a dark afternoon or see ourselves in the bathroom mirror first thing in the morning, we expect white light - and the white light is a mixture of many colors.

It is possible to achieve this with LEDs by covering them with a luminescent material.

For white light, an amber-colored luminophore is usually applied to blue LEDs. It is the same principle as applying crepe paper for light to get the red or blue light luxury.

A few years ago, the team collaborated with Philips Lumileds Schnick Development Center to develop these materials not only for the LED. It is still on the market, which are used in LED lights are made by the parent company's development center, Philips.

better efficiency

The new luminophore also promised to create a more efficient LED light.

LED lights are currently using luminescent materials that add too much red to light. The resulting wavelength is similar to infrared light, the one that the human eye can not fully process.

And we can not light the light we can not "see" - and a waste of energy.

Scientists say a new luminescent material they fix this problem. It adds less red color to mix and as a result, the LED lights are up to 14 percent more energy efficient than current ones.
