求翻譯:LED上游磊芯片制作約占制造成本7成,其原理為將一層或多層單晶層成長于基板上,形成含有多種化學元素累積的芯片,其發光顏色 與亮度由磊晶材料決定;中游則將磊芯片蒸鍍金屬后制作電極,經蝕刻再切割崩裂成晶粒;下游則封裝晶粒,制成如指示燈、數字顯示器及紅外線發射器等各式 LED產品。而LED的產品特性,因其發光原理為將化合物半導體施加電流,透過電子與電洞的結合,其過剩能量以光的形式釋放出來,達到發光效果,因其發光 現象屬冷性發光,故無須暖燈時間,且壽命可長達10萬小時以上,并具有體積小、用電省、反應速度快及高可靠度等等優點。是什么意思?![]() ![]() LED上游磊芯片制作約占制造成本7成,其原理為將一層或多層單晶層成長于基板上,形成含有多種化學元素累積的芯片,其發光顏色 與亮度由磊晶材料決定;中游則將磊芯片蒸鍍金屬后制作電極,經蝕刻再切割崩裂成晶粒;下游則封裝晶粒,制成如指示燈、數字顯示器及紅外線發射器等各式 LED產品。而LED的產品特性,因其發光原理為將化合物半導體施加電流,透過電子與電洞的結合,其過剩能量以光的形式釋放出來,達到發光效果,因其發光 現象屬冷性發光,故無須暖燈時間,且壽命可長達10萬小時以上,并具有體積小、用電省、反應速度快及高可靠度等等優點。
