History of High Power IR LED
The concept of the light-emitting diode (LED) was first proposed by O. Hull in 1906, and it was not until the 1960s that the first LED was developed by Nick Holonyak at General Electric. In the early days, LEDs were primarily used for indicator purposes due to their low light output. However, with the advancement of semiconductor technology, the development of high-power IR LEDs has become possible, and they have found extensive applications in various fields.
Technology of High Power IR LED
High Power IR LED technology involves the use of semiconductor materials with specific bandgap properties to emit infrared light. The most commonly used materials for IR LED production include Gallium Arsenide (GaAs), Aluminum Gallium Arsenide (AlGaAs), and Aluminum Gallium Indium Arsenide (AlGaInAs). These materials can emit infrared light with wavelengths ranging from 700nm to 3000nm, depending on the application requirements.
The key factors affecting the performance of high power IR LEDs include the quality of the semiconductor materials, the structure of the LED chip, and the packaging technology. The LED chip structure typically consists of a p-n junction, with the n-type layer serving as the emitter and the p-type layer as the collector. The doping concentration and thickness of these layers are carefully controlled to optimize the light output and efficiency of the LED.
