Infrared LED lamp beads, also known as infrared emitting diodes (IR LEDs), have become increasingly popular in various applications due to their compact size, low power consumption, and efficient heat dissipation. This article provides an in-depth introduction to the infrared LED lamp bead industry, covering its history, technology, applications, market trends, and future prospects.

History and Development of Infrared LED Lamp Beads

The concept of infrared LED lamp beads dates back to the early 20th century when scientists began to experiment with semiconductor materials. However, it was not until the 1960s that the first practical infrared LED was developed. Since then, the technology has undergone significant advancements, with improvements in efficiency, lifespan, and cost-effectiveness. The early infrared LEDs were primarily used in industrial applications, such as remote controls and optical communication systems. Over time, the technology has expanded to include consumer electronics, automotive, medical, and security sectors. Today, infrared LED lamp beads are an integral part of numerous everyday devices, thanks to their versatility and reliability.

Technology of Infrared LED Lamp Beads

Infrared LED lamp beads are made from semiconductor materials, typically gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). These materials emit infrared light when an electric current is applied, making them ideal for applications that require invisible light. The manufacturing process of infrared LED lamp beads involves several steps, including epitaxial growth, wafer slicing, dicing, and bonding. During epitaxial growth, a thin layer of semiconductor material is deposited on a substrate to create a p-n junction. The wafer is then sliced into individual chips, which are diced into smaller pieces and bonded to substrates for further processing. The key parameters of an infrared LED lamp bead include its wavelength, forward voltage, and forward current. The wavelength determines the color of the emitted light, with shorter wavelengths producing a more intense infrared signal. The forward voltage and current are critical for ensuring the LED operates efficiently and reliably.
