Working Principles of Patch Infrared LEDs

Patch infrared LEDs are based on the principles of solid-state lighting, where light is generated through the interaction of electrons and holes in a semiconductor material. The process begins with the injection of electrons and holes into the p-n junction of the semiconductor, typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When these electrons and holes recombine, they release energy in the form of photons, which correspond to infrared light. The key to the efficiency of patch infrared LEDs lies in their design. These LEDs are mounted on a substrate, which is typically made of ceramic or glass. The substrate provides a stable and thermally conductive platform for the LED, allowing for efficient heat dissipation. Additionally, the use of advanced packaging techniques ensures minimal light loss and optimal light extraction.
