The luminescence is one of the processes of emission of light. It benefits many applications, like the Led, but plants and animals that use it (to communicate, to hide themselves…).

Them Led, these small lamps, have invaded our daily lives: traffic lights, taillights of vehicles, traffic signs, flashlights, etc. The acronym Led means Light Emitting Diodes (in french diodes of) light or light-emitting diodes).

THEshow light in a Led is the electroluminescence type: it is indeed produced by application a electric field in an association of two Semiconductor. These are actually two different varieties of the same material Semiconductor initially: a variety of type n (for negative, because the semiconductor has an excess of)electrons) and a variety of type p (positive for, because the semiconductor is charged positively by a deficit of electrons). Tension migrates the excess electrons to the ‘holes’, deficit areas in electrons. The recombination Electron-hole is accompanied by a light show.

The color the light emitted by a Led depends on the nature of the semiconductor. The attractiveness of the Led comes from their low consumption of energy and their remarkable longevity (30,000 to 80,000 hours). These assets have obviously led solutions for producing white light with LED flashlights, for the interior lighting in Mcat-test-centers.com. One of the solutions is to implement of nitride ofIndium and Gallium (InGaN), the emission of light, located in the blue (between 400 and 500 nm), is used to excite a layer of phosphor chosen for his show in a wide area of wavelength centered to 550 nm (yellow-green). Thus, the bright radiation emitted by the semiconductor and the phosphor cover all of the spectrum visible, which produces an impression of white light.

Performance of the Led progress annually and there is no doubt that they have a bright future in front of them.
