Revolutionizing Technology: The Power of Infrared LED Innovations

Infrared LED, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied. It is widely used in various fields such as remote control, automotive, medical, and industrial applications. In this article, we will introduce the infrared LED industry, covering its history, technology, market trends, and future development.

History of Infrared LED

The history of infrared LED can be traced back to the 1960s when scientists discovered that certain semiconductors could emit infrared light when forward biased. In the early days, infrared LEDs were primarily used in applications such as burglar alarms and remote controls. With the advancement of technology, the applications of infrared LEDs have expanded to more fields, making it an essential component in modern electronics.

Technology of Infrared LED

Infrared LED technology involves the use of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and aluminum gallium arsenide (AlGaAs), to emit infrared light. The structure of an infrared LED typically includes a p-n junction, where electrons and holes recombine to produce photons. The wavelength of the emitted light is determined by the bandgap of the semiconductor material used.

Several factors affect the performance of an infrared LED, including its forward voltage, forward current, and light output. To enhance the performance of infrared LEDs, manufacturers have employed various techniques, such as surface texturing, antireflective coatings, and quantum wells. These techniques help to improve the light extraction efficiency, reduce the forward voltage, and increase the light output.
