Technology of Mini IR LED
Mini IR LED technology is based on the principle of semiconductor physics. When a forward voltage is applied to a semiconductor material, electrons and holes are generated, which recombine and emit light. The color of the emitted light depends on the bandgap of the semiconductor material.
The key factors that determine the performance of a mini IR LED include its size, material, and structure. Mini IR LED chips are typically smaller than 1mm in diameter, which allows them to be integrated into various applications with high density. The most commonly used materials for mini IR LED are gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium indium phosphide (AlGaInP).
The structure of a mini IR LED includes an n-type layer, a p-type layer, and an active region. The active region is where the recombination of electrons and holes occurs, and light is emitted. To improve the efficiency and lifespan of mini IR LED, various surface treatment and packaging technologies are applied.
