光發射器件(Light-Emitting Devices, LED) 是指通過電能或其他能量激發後能夠主動發出可見光或非可見光(如紅外光、紫外光)的半導體電子器件。其核心原理是半導體材料中的電子與空穴複合時,以光子形式釋放能量,實現電光轉換。以下從技術定義、分類及原理進行詳細解釋:
光發射器件基于電緻發光(Electroluminescence) 效應工作:當電流通過半導體PN結時,電子從高能級躍遷至低能級,多餘能量以光子形式釋放。其發光波長由半導體材料的能帶間隙(Bandgap)決定,公式可表示為: $$ E_g = frac{hc}{lambda} $$ 其中 ( E_g ) 為能帶間隙,( h ) 為普朗克常數,( c ) 為光速,( lambda ) 為發射光波長。通過調整材料組分(如InGaN、AlGaAs),可精确控制發光顔色。
