Diode infrared (IR) technology has emerged as a crucial component in the field of infrared detection and communication. With its ability to efficiently convert infrared light into electrical signals, diode IR devices have found wide applications in various industries, including consumer electronics, automotive, and medical fields. This article aims to provide an in-depth introduction to the diode IR industry, covering its basic principles, applications, market trends, and future prospects.

Basic Principles of Diode IR Technology

Diode infrared technology is based on the principle of photoelectric effect, where photons (light particles) with sufficient energy strike a semiconductor material, causing electrons to be emitted and creating an electrical current. In the case of diode IR, the semiconductor material used is typically a combination of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which are known for their high efficiency in converting infrared light to electrical signals. The diode IR sensor consists of a photodiode and a photo-transistor. When infrared light falls on the photodiode, it generates an electrical current, which is then amplified by the photo-transistor. The output signal can be further processed to provide information about the intensity, wavelength, and direction of the infrared light.
