LED (發光二極體)

發光二極體 (LED) 是一種半導體裝置,在電流流經它時會發出可見光。光線並非特別明亮,但是在大部分的 LED 中,光線是單色,發生於單一波長。


LED 半導體元件所用的材質會決定其色彩。目前照明系統採用的 LED 有兩種主要類型:磷化鋁銦鎵 (AlGaInP 或 AlInGaP) 合金用於紅、橙與黃色 LED;以及氮化銦鎵 (InGaN) 合金用於綠、藍與白色 LED。這些合金的成份稍有變化就會改變發光的顏色。LED 的輸出可從紅色 (波長約 700 奈米) 至藍紫色 (約 400 奈米)。某些 LED 放射紅外線 (IR) 能量 (830 奈米以上);這種裝置稱為紅外線發射二極體 (IRED)。


與照明應用中採用的最典型光源相較之下,LED 仍然會具有相對低的光輸出,因此將繼續採陣列封裝以及在該應用中實用的其他配置。目前,單一白色 LED 封裝可達將近 100 流明。當然,光輸出視波長而異。LED 因為其高效率與低能量而具有重要地位,已經開始取代最傳統的光源。LED 針對一般照明應用而整合到燈泡與燈具中。LED 的尺寸小巧,提供獨特的設計契機。某些 LED 燈泡解決方案可能在實體上類似燈泡,較能搭配傳統燈泡的外觀。


LED 在照明設備的外觀尺寸上提供龐大的創新機會,而且應用範圍比傳統照明技術更寬廣。LED 採用散熱器吸收 LED 產生的熱量,然後將它消散到周圍環境中。此舉讓 LED 避免過熱和燒毀。LED 在其壽命期間能成功發揮效能的最重要單一因素,就是散熱管理。LED 的運作溫度越高,光線劣化的速度越快,使用壽命也隨之縮短。
