History of High Output IR LED

The development of high output IR LED can be traced back to the early 20th century. In 1908, Henry Joseph Round, a British physicist, discovered that certain materials could emit light when subjected to an electric current. This discovery laid the foundation for the development of the first LED, which was a red LED. Over the years, researchers have made significant progress in the field of IR LED technology, leading to the development of high output IR LED.

Technology of High Output IR LED

High output IR LED technology involves the use of semiconductor materials, such as gallium arsenide (GaAs), indium gallium arsenide (InGaAs), and indium phosphide (InP), to create a diode that emits infrared light. The key to achieving high output is the design of the LED's structure, which includes the active region, the p-n junction, and the metal contact. The active region is where the light is emitted. By using a wide bandgap semiconductor material, the LED can produce more intense light. The p-n junction is responsible for the electric current flow, while the metal contact provides a path for the current to enter the LED. The key factors that affect the performance of high output IR LED include the material quality, the epitaxial layer structure, the device structure, and the packaging technology. Advances in these areas have led to the development of high output IR LED with higher efficiency, longer lifespan, and better stability.
