Technology of High Power Infrared LED Diodes

High power infrared LED diodes are semiconductor devices that emit infrared light when an electric current passes through them. The key components of these diodes include a p-n junction, a chip, a lead frame, and a lens. The p-n junction is the active region where the infrared light is generated, while the chip is the semiconductor material that carries the current. The lead frame provides electrical connections, and the lens focuses the emitted light into a narrow beam. The manufacturing process of high power infrared LED diodes involves several steps, including epitaxial growth, wafer slicing, dicing, and packaging. Epitaxial growth is a process where a thin layer of semiconductor material is deposited on a substrate to form a p-n junction. Wafer slicing involves cutting the epitaxial wafer into individual chips, and dicing further divides the chips into smaller units. Finally, the chips are packaged with a lens and lead frame to form a high power infrared LED diode.
