The technical revolution from Germany:
Photon pump® – LED lenser® - choose your favorite colour (white, blue, green, red or orange).
Length 60 mm
Diameter 13 mm
Runs with 3 button cells 1.5 V; type AG 13
Life time of the diode: up to 100 000 hours
Operation time with three button cells: about 100 hours
The fascinating power station for your key ring. A sophisticated high-tech gift. Just like a laser pointer but much more attractive.
Usual flashlights resemble to cave fire compared with the photon pump. Burning wood and the filament of a bulb are emitting a high amount of heat. These high-end luminescent lensers (artificially grow semiconductor crystals doped with foreign atoms, advanced chip technology, type 5.2000, high-quality microswitch PS 22E09) are cold emitting monochrome photon pumps.
Using quantum physics we can explain the principle of these devices. The electrons going around the nucleus (semiconducting material is GaN, SiC, (Al,In,Ga)P) are put to a higher energy level by an electrical current. A very short time later they go back to their former energy level thus emitting the absorbed electrical energy as light.
The wavelength (colour) of the emitted light is depending on the band gap and layer structure of the semiconductor.
People having no favourite colour are facing a hard decision between the five light colours (470 to 660 nanometers).
