光发射器件（Light-Emitting Devices, LED） 是指通过电能或其他能量激发后能够主动发出可见光或非可见光（如红外光、紫外光）的半导体电子器件。其核心原理是半导体材料中的电子与空穴复合时，以光子形式释放能量，实现电光转换。以下从技术定义、分类及原理进行详细解释：
光发射器件基于电致发光（Electroluminescence） 效应工作：当电流通过半导体PN结时，电子从高能级跃迁至低能级，多余能量以光子形式释放。其发光波长由半导体材料的能带间隙（Bandgap）决定，公式可表示为： $$ E_g = frac{hc}{lambda} $$ 其中 ( E_g ) 为能带间隙，( h ) 为普朗克常数，( c ) 为光速，( lambda ) 为发射光波长。通过调整材料组分（如InGaN、AlGaAs），可精确控制发光颜色。
