Introducing Infrared Patch LEDs: The Future of Lighting Technology

Introduction to Infrared Patch LEDs

Infrared patch LEDs (Infrared LEDs) are a cutting-edge lighting technology that has gained significant attention in recent years. These LEDs emit light in the infrared spectrum, which is invisible to the human eye. Despite their invisible nature, infrared patch LEDs offer numerous advantages over traditional lighting solutions, making them a popular choice for various applications. This article aims to provide an in-depth overview of infrared patch LEDs, their working principle, applications, advantages, and future prospects.

Working Principle of Infrared Patch LEDs

Infrared patch LEDs operate on the principle of electroluminescence, where a semiconductor material emits light when an electric current passes through it. The semiconductor material used in these LEDs is typically gallium arsenide (GaAs) or gallium nitride (GaN), which has a direct bandgap structure. This direct bandgap structure allows the electrons to recombine with holes, emitting infrared light in the process. The working principle of an infrared patch LED can be broken down into the following steps: 1. Electric current is applied to the LED, causing electrons to move towards the cathode. 2. As the electrons move towards the cathode, they collide with the holes in the semiconductor material. 3. The collision of electrons and holes results in the recombination of the two particles, releasing energy in the form of infrared light. 4. The emitted light is then focused and directed through a lens or reflector to achieve the desired beam pattern.
