How Patch Infrared LEDs Work

Patch infrared LEDs operate on the principle of semiconductor physics. They consist of a semiconductor material, typically gallium arsenide (GaAs), which emits light when an electric current passes through it. The emitted light is in the infrared spectrum, which ranges from 700 nanometers to 1 millimeter in wavelength. This light is not visible to the naked eye but can be detected by specialized sensors and cameras. The key components of a patch infrared LED include the semiconductor chip, a lens, and a package. The semiconductor chip is the heart of the LED, where the light is generated. The lens is designed to focus the emitted light into a specific beam pattern, ensuring optimal performance. The package, which includes the semiconductor chip and lens, is mounted on a substrate using surface mount technology.
