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(jiàn)的LED驅(qū)動(dòng)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L(zhǎng)ED燈珠的類型，從草帽燈珠，食人魚(yú)這些都已經(jīng)消失的封裝開(kāi)始，到SMD，COB，CSP，日新月異，還需要適時(shí)補(bǔ)充。LED燈珠的組成LED燈珠由以下幾個(gè)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(méi)有導(dǎo)線的對(duì)比，如：發(fā)光原理從物理學(xué)角度來(lái)理解：當(dāng)電流通過(guò)晶片時(shí)，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(jiàn)的光）。不同材料的半導(dǎo)體會(huì)產(chǎn)生不同顏色的光色，如紅光、綠光、藍(lán)光等等。所以，沒(méi)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(méi)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(jiǎng)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(xiàng)重大的貢獻(xiàn)在2014年授予他諾貝爾物理學(xué)獎(jiǎng)。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。</p><p>雙隔離安全型LED投光燈產(chǎn)品名稱：雙隔離安全型LED工礦燈（吊燈）產(chǎn)品關(guān)鍵詞：雙隔離、安全型、內(nèi)置雙燈、進(jìn)口芯片、防眩透鏡、帶熱保護(hù)隔離型防水驅(qū)動(dòng)、高功率因數(shù)、AI防水風(fēng)扇防蚊蟲(chóng)、全鋁燈體。產(chǎn)品名稱：雙隔離安全型LED投光燈光源套件產(chǎn)品關(guān)鍵詞：雙隔離、安全型、內(nèi)置雙燈、進(jìn)口芯片、防眩透鏡、帶熱保護(hù)隔離型防水驅(qū)動(dòng)、高功率因數(shù)、AI防水風(fēng)扇防蚊蟲(chóng)、全鋁燈體。光源參數(shù)：原裝SAMSUNG芯片，3535燈珠、純金線、EMC支架、110lm/w、顯色指數(shù)≧80。光源防護(hù)：進(jìn)口PC料模壓成型透鏡罩，配有防護(hù)網(wǎng)。雙隔離安全型LED工礦燈（吊燈）產(chǎn)品關(guān)鍵詞：雙隔離、安全型、內(nèi)置雙燈、進(jìn)口芯片、防眩透鏡、帶熱保護(hù)隔離型防水驅(qū)動(dòng)、高功率因數(shù)、AI防水風(fēng)扇防蚊蟲(chóng)、全鋁燈體。技術(shù)特點(diǎn)：1、標(biāo)稱功率：150W（內(nèi)置雙燈）。本產(chǎn)品提供一路50W和一路100W兩路輸出線，可以并聯(lián)為150W，實(shí)現(xiàn)50W/100W/150W三檔功率組合，場(chǎng)館LED防震節(jié)能燈，適合外接三路線控分光器或遙控分光器，也適合分別外接聲控、光控、時(shí)控、紅外、微波感應(yīng)等自控開(kāi)關(guān)，工廠LED防震節(jié)能燈，或分出一路接后備電源提供應(yīng)急照明。2、觸電防護(hù)：雙隔離型（安全，LED防震節(jié)能燈，不漏電）。本產(chǎn)品采用隔離式燈具。上海先盛照明電器有限公司是一家專業(yè)提供LED的公司，有想法的不要錯(cuò)過(guò)哦！</p><div
