Technology of Infrared LED Lamp Beads

The technology behind infrared LED lamp beads involves the use of semiconductor materials that emit infrared light when an electric current is applied. The most commonly used materials include gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium indium phosphide (AlGaInP). The manufacturing process of infrared LED lamp beads involves several steps: 1. Material Growth: The first step is to grow a thin layer of semiconductor material on a substrate using techniques such as molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). 2. Structural Design: The next step is to design the structure of the LED, which includes the p-n junction, the reflector, and the lens. The reflector is used to concentrate the light output, while the lens helps to focus the light into a specific beam. 3. Doping: Doping is the process of adding impurities to the semiconductor material to alter its electrical properties. This step is crucial for achieving the desired emission characteristics of the LED. 4. Mounting: The final step is to mount the LED on a substrate, which provides electrical connections and thermal management.
