Just a few years ago, the LED (English for light-emitting diode, in German light-emitting diode) is known at most as display lighting in technical devices. It seemed unrealistic that such an LED could illuminate entire rooms. That has changed in the meantime: LEDs have long since made their triumphant advance in modern lamps and luminaires. There is hardly a manufacturer who is not aware of this. And the EU lightbulb ban with the end of all standard incandescent lamps with an output of more than 10 watts has done the rest to Saving energy with light to bring into the consciousness of consumers. As the current generation of light sources, luminaires and lamps with LEDs are increasingly in focus.

LED - what does that mean exactly?

While a twisted metal thread lights up in the light bulb, an LED works differently. An LED is on electrical componentcontaining a small crystal that is excited to glow by electricity. This explains the name: light-emitting diode - LED. In contrast to other light sources, LEDs convert electricity into light without great loss of energy take place. An LED can convert up to 30 percent of the electricity into light. In comparison: with a conventional light bulb, only 5 percent of the electricity generates light. The rest goes as warmth lost. An LED lamp can save up to 90 percent electricity compared to a conventional incandescent lamp.
