LED靠電子在能帶間的躍遷來(lái)發(fā)光，它光譜單一，不含紅外部分，不同于傳統(tǒng)的固體熱致發(fā)光光源的白熾燈。因此將LED稱作“冷”光源，其實(shí)LED芯片*能將不到10%的電能轉(zhuǎn)化為光能，其余90%轉(zhuǎn)化為熱能。而且這些熱能的大部分只能靠傳導(dǎo)散發(fā)出去。因此，良好的散熱設(shè)計(jì)對(duì)LED的正常使用非常重要。2、LED對(duì)工作溫度要求嚴(yán) LED的芯片對(duì)溫度異常敏感，這也是半導(dǎo)體的共性。從下列的圖及表格中可以看出LED的使用壽命與結(jié)溫(Tj)關(guān)系。而當(dāng)LED照明產(chǎn)品的生產(chǎn)量大幅度提升后，相關(guān)的制造業(yè)和配套服務(wù)業(yè)也得到了發(fā)展。福建三防燈具</p><p
