LED靠電子在能帶間的躍遷來發(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)計對LED的正常使用非常重要。2、LED對工作溫度要求嚴(yán) LED的芯片對溫度異常敏感，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。上海室外三防燈其看似只是款簡單的照明燈具，但是由于其很高的市場定位決定了客戶對這款產(chǎn)品的品質(zhì)要求極為苛刻。</p><div style="width:100%;text-align: center;"><img
