LED light theory

Light-emitting diodes, commonly known as LED. Light-emitting diode is just a tiny light bulb. But unlike common incandescent bulbs, light-emitting LED High Bay Light diode is no filament, but not particularly hot, it is merely by the semiconductor material in the electron moving it a light-emitting. Light emitting diodes no filament to burn out, so the longer life expectancy. And light-emitting diode small plastic bulb makes light-emitting diodes are more durable, plus LED can be easier to fit electronic circuit.

 The traditional incandescent light-emitting process consists of a lot of heat, this is a waste of energy. The heat emitted by the light-emitting diodes are very few, relatively speaking, more power to reduce the demand for energy is the greater the degree of direct light. A form of energy alone, one can be atoms released. Is a lot of energy and drive, but not quality like tiny particles composed of small bundles. These particles are called photons, which is the most basic unit of light.

The photon is released because electrons move. Atom, the electron orbital shape moving atoms around. Electrons in different orbital unequal energy. Usually have a greater energy electrons orbit moving away from nuclear. When electrons jump from a lower orbit to a higher orbit, theLED High Bay Lights IP65  energy levels increased and, in turn, would release energy electrons fall from a higher orbital to a lower orbital. Energy is based on a the photon form of release.

 Higher energy decreased release of higher-energy photons, it is characterized by its high frequency. The free electrons from the electron-hole P-type layer through the diode falls empty. This includes orbital of the drops from the conduction band to a lower, so the electronic release of energy is the form of a photon. This will happen in any diode, when the diode is a substance, you just can see the photons. In standard silicon diodes atoms, for example, when the electron drops to a relatively short distance atoms in such a manner arranged. The results, due to the electronic frequency so low human eyes can not be visible. Visible LED, such as used in the digital display-style clock, the size of the gap determines the frequency of the photon, in other words, is to decide the color of the light.

When all diodes emit light, the majority are not very effective. Ordinary diode, the semiconductor material itself to attract a lot of light and the end of. The light-emitting diode is covered by a plastic bulb concentrated light in a specific direction. Semiconductor parts prices have been significantly reduced over the past 10 years, I believe the future of light-emitting diodes in a wider range of applications, and is aLED Bulb Light more cost-effective lighting option.
