This article aims to provide an in-depth introduction to the high power infrared LED diode industry, covering its history, technology, applications, market trends, and future prospects.

History and Development of High Power Infrared LED Diodes

High power infrared LED diodes have a relatively short history compared to other types of LEDs. The development of infrared LED technology dates back to the 1960s when the first infrared LEDs were invented. However, it was not until the late 1990s that high power infrared LED diodes began to gain attention from the industry. The early infrared LEDs were primarily used in simple applications such as remote controls and optical communication. With the advancement of semiconductor technology, the efficiency and brightness of infrared LEDs improved significantly. This led to the development of high power infrared LED diodes, which could emit light with higher intensities and cover a wider range of wavelengths.

Technology of High Power Infrared LED Diodes

High power infrared LED diodes are based on the same principles as other types of LEDs, but with some key differences. The main components of an infrared LED diode include a semiconductor material, a p-n junction, and a package. The semiconductor material is responsible for emitting light when an electric current passes through it. The most commonly used semiconductor materials for high power infrared LED diodes are gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs). These materials have excellent infrared emission properties and can be doped with different elements to achieve the desired wavelength and intensity. The p-n junction is the heart of the LED, where the electrons and holes recombine to emit light. High power infrared LED diodes require a large number of recombination events to produce high intensities of light. To achieve this, the p-n junction is designed with a high doping concentration and a large active area. The package is used to protect the LED and provide electrical and thermal connections. High power infrared LED diodes often require heat sinks to dissipate the heat generated during operation.
