LED Illumination


 

What is LED really?

LED (Light Emitting Diode) is a lightdiode. An LED is an electronic light source, a so-called semiconductor. LED's work in an entirely different premise that match transistors or other electronic equipment along those lines. There is no wire to burn. It is also a much more efficient light source that produces significantly more light per watt than normally seen. 

What is LED?
lightdiodes are real heroes in the electronics world. They do different jobs and are found in all kinds of equipment. Among other things, they transmit the information from remote controls, light up watches and tells you when your devices are turned on. If they gather, they can form images on a television screen or illuminate a traffic light.

How does a LED?
An LED is a device consisting of two different semiconductor materials contaminated. P-material and the N-material. Therefore is LED also called a semiconductor. P-material, also called the anode, are contaminated in such a way that there is a deficit of free electrons. N-material - also called the cathode, is contaminated in some way so there is an excess of free electrons.

When there is passing  current through the LED,  there is released a so-called photons which are generated when the electrons goes from the cathode to the anode. Photons are free electron emitting a light, which is used by the human eye. The release of photons takes place when electrons must go through a micro hole in the LED chip in which they have to release photons to pass through the hole.

The principle behind the LED was already invented in 1907 by a man named Henry Joseph Round. He discovered that if he let a current pass a silicon carbide (SiC) crystal, it began to emit a faint light.
