Learning more about LED

More and more people are getting interested with the very useful light-emitting diode, or more popularly known as LED. This is a very reliable semiconductor kind of light source. In the year 1962, it was introduced to the public as an electronic component that is very convenient to make use of.

When you take a close look at LEDs, you would be able to see that it is based on what is known as semiconductor diode. The moment that you try to switch the diode on, the electrons are given the means to go and recombine in areas where there are holes that are encapsulated in the device. This, in turn, releases energy, or it could be photons. The effect is known as electroluminescence, and the light’s color, which corresponds to the photon’s energy, may be ascertained by the gap of energy, found on the semiconductor. Most of the time, the LEDs are considered to be small in terms of area, which may possibly measure 1 mm2. With the use of certain kinds of optical components, the pattern of radiation, as well as the reflection is shaped by these said components. There is no doubt that there are numerous advantages that may be derived from LEDs, in the form of radiant or luminous light sources and an example would be a decrease on the consumption of energy.
