In this comprehensive industry introduction, we will delve into the world of LED infrared LEDs, exploring their technology, applications, market trends, and future prospects.

Introduction to LED Infrared LEDs

LED infrared LEDs, also known as infrared diodes or IR LEDs, are semiconductor devices that emit infrared light when an electric current is applied to them. Unlike visible light, infrared light is not visible to the human eye but is detectable by specialized sensors and devices. These LEDs are designed to emit light in the infrared spectrum, which ranges from 700 nanometers (nm) to 1 millimeter (mm) in wavelength.

How LED Infrared LEDs Work

The working principle of LED infrared LEDs is based on the semiconductor material used in their construction. Typically, these LEDs are made of gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs) materials. When an electric current passes through the semiconductor material, it excites electrons, causing them to move from the valence band to the conduction band. As the electrons return to the valence band, they release energy in the form of photons, which are emitted as infrared light.
