Advantages of Semiconductor Light Emitting Diodes Semiconductor light emitting diodes are extremely popular in optoelectronic systems because of their simple structure, small size, low operating current, ease of use, and low cost.
Under forward bias, a semiconductor PN junction or a structure similar thereto can emit visible or near-infrared light. This device that directly converts electrical energy into light energy is called a light-emitting diode (LED). Welcome to the company **http://
Luminescence is the process by which energy stored in a certain manner inside an object is converted into light radiation. The optical radiation of a luminescent object is produced when the excited electrons in the material transition to the ground state. A semiconductor (mainly a compound semiconductor composed of Group III and Group V elements in the periodic table) is a current-excited electroluminescent device.
The phenomenon of electroluminescence was discovered in 1923, and it did not attract people's attention. Laser Diodes With the development of modern technology, new requirements have been put forward for light-emitting devices. It is hoped that the light-emitting tubes are simple, reliable, long-life, low-priced, and compact. So the research on electroluminescence since the 1960s is very active.
