diode縮寫）。它是一種通過控制半導體發(fā)光二極管的顯示方式，由鎵（Ga）與砷（As）、磷（P）、氮（N）、銦（In）的化合物制成的二極管，當電子與空穴復合時能發(fā)射出可見光，因而可以用來制成發(fā)光二極管。在電路及儀器中作為指示燈，或者組成文字或數(shù)字顯示。磷砷化鎵二極管發(fā)紅光，磷化鎵二極管發(fā)綠光，碳化硅二極管發(fā)黃光，銦鎵氮二極管發(fā)藍光。</p><p style="text-indent:25px">LED模壓封裝：將壓焊好的LED支架放入模具中，將上下兩副模具用液壓機合模并抽真空，將固態(tài)環(huán)氧放入注膠道的入口加熱用液壓頂桿壓入模具膠道中，環(huán)氧順著膠道進入各個LED成型槽中并固化。LED固化與后固化，固化是指封裝環(huán)氧的固化，一般環(huán)氧固化條件在135℃，1小時。模壓封裝一般在150℃，4分鐘。后固化是為了讓環(huán)氧充分固化，同時對LED進行熱老化。后固化對于提高環(huán)氧與支架（PCB）的粘接強度非常重要。一般條件為120℃，4小時。從指示燈水平到超過通用光源水平的技術(shù)**導致各種新的應(yīng)用。LED的控制模式有恒流和恒壓兩種，有多種調(diào)光方式，比如模擬調(diào)光和PWM調(diào)光。</p><div
