本篇文章介紹如何判斷燈珠類型，燈珠的串并數(shù)，以及判斷燈珠板的額定輸入電壓和電流；另外，還介紹了市面上常見的LED驅(qū)動器的類型，參數(shù)規(guī)格，以及如何配套好你想要的燈珠板。LED燈珠LED燈珠的類型，從草帽燈珠，食人魚這些都已經(jīng)消失的封裝開始，到SMD，COB，CSP，日新月異，還需要適時補(bǔ)充。LED燈珠的組成LED燈珠由以下幾個部分組成：晶片，基板支架，導(dǎo)線，熒光粉，光學(xué)透鏡，支架塑料，如下圖：也有CSP就是沒有導(dǎo)線的對比，如：發(fā)光原理從物理學(xué)角度來理解：當(dāng)電流通過晶片時，N型半導(dǎo)體內(nèi)的電子與P型半導(dǎo)體內(nèi)的空穴在發(fā)光層劇烈地碰撞復(fù)合產(chǎn)生光子，以光子的形式發(fā)出能量（即大家看見的光）。不同材料的半導(dǎo)體會產(chǎn)生不同顏色的光色，如紅光、綠光、藍(lán)光等等。所以，沒有熒光粉的，直接就是晶片本身發(fā)光顏色，一般彩色燈珠都是這種類型。但是，到目前為止還沒有任何一種半導(dǎo)體材料能發(fā)出白色的光。這里就需要提到一位諾貝爾獎獲得者——中村修二博士。他發(fā)明出了藍(lán)光LED，由此也為白光LED奠定了一定的基礎(chǔ)?；谶@項重大的貢獻(xiàn)在2014年授予他諾貝爾物理學(xué)獎。至于藍(lán)光LED是如何轉(zhuǎn)變?yōu)榘坠釲ED，大的原因在于晶片中多了一層熒光粉。LED，就選上海先盛照明電器有限公司，有想法的可以來電咨詢！吉林節(jié)能LED三防燈</p><p
