Infrared LED lamp beads, also known as infrared emitting diodes, have become an essential component in various industries due to their unique properties and wide range of applications. This article aims to provide an in-depth introduction to the infrared LED lamp bead industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared LED Lamp Beads

The concept of infrared light has been known for centuries, but it was not until the 20th century that infrared LED lamp beads were developed. In the 1960s, the invention of the first infrared LED by Nick Holonyak Jr. marked the beginning of a new era in infrared technology. Since then, the technology has evolved significantly, with continuous improvements in efficiency, brightness, and lifespan.

Technology of Infrared LED Lamp Beads

Infrared LED lamp beads are made of semiconductor materials, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared light when an electric current is applied. The key parameters of an infrared LED lamp bead include wavelength, luminous intensity, and forward voltage. The wavelength of an infrared LED lamp bead determines the color of the light it emits. Common wavelengths range from 780 nm to 3,000 nm, with different applications requiring specific wavelengths. The luminous intensity refers to the brightness of the light, which is measured in milliwatts (mW). The forward voltage is the voltage required to make the LED emit light.
