850 infrared lamp beads, also known as 850nm infrared emitting diodes (IR LEDs), are a specialized type of semiconductor device that emits infrared light at a specific wavelength of 850 nanometers. These lamp beads are widely used in various applications, including automotive sensors, consumer electronics, and industrial automation. This article aims to provide a comprehensive introduction to the industry of 850 infrared lamp beads, covering their technology, applications, market trends, and future prospects.

Technology of 850 Infrared Lamp Beads

The technology behind 850 infrared lamp beads revolves around the use of semiconductor materials, primarily gallium arsenide (GaAs), which are capable of emitting infrared light when an electric current is applied. Here's an overview of the key aspects of the technology:

1. Semiconductor Material

The core of an 850 infrared lamp bead is a semiconductor material, typically GaAs, which has a direct bandgap at around 850nm. This bandgap allows the material to efficiently emit infrared light at this specific wavelength when excited by an electrical current.

2. LED Structure

The structure of an 850 infrared lamp bead consists of a p-n junction, which is formed by doping the GaAs material with impurities to create an electrically conductive region (n-type) and a non-conductive region (p-type). When a forward bias voltage is applied, electrons from the n-type region recombine with holes from the p-type region, releasing energy in the form of photons at the 850nm wavelength.

3. Packaging

After the LED chip is fabricated, it is mounted on a substrate and encapsulated in a package that protects the chip and provides electrical connections. The package may include a lens to focus the emitted light in a particular direction, enhancing the performance of the lamp bead.

Applications of 850 Infrared Lamp Beads
