在選擇和(he)設計LED車燈(deng)電(dian)子驅動(dong)電(dian)源(yuan)時(shi)要(yao)(yao)考慮(lv)到一下幾點：1.恒流輸(shu)出供(gong)電(dian)方(fang)式：多路恒流輸(shu)出，組合靈(ling)活，一路LED故障(zhang)，不影響(xiang)其(qi)他(ta)LED工作，成本(ben)略(lve)高(gao)；直(zhi)接恒流供(gong)電(dian)，LED串(chuan)聯或并聯運行，成本(ben)低一點，但(dan)靈(ling)活性(xing)差(cha)，某(mou)個LED故障(zhang)，會影響(xiang)其(qi)他(ta)LED運行。這兩種形式，在一段時(shi)間內并存，多路恒流輸(shu)出供(gong)電(dian)方(fang)式，在成本(ben)和(he)性(xing)能方(fang)面(mian)會較好。2.浪(lang)(lang)(lang)涌(yong)保護：LED抗浪(lang)(lang)(lang)涌(yong)的(de)(de)能力是比較差(cha)的(de)(de)，特別是抗反向電(dian)壓能力。加強(qiang)這方(fang)面(mian)的(de)(de)保護也很重要(yao)(yao)，LED驅動(dong)要(yao)(yao)有抑制(zhi)浪(lang)(lang)(lang)涌(yong)的(de)(de)侵(qin)入，保護LED不被(bei)損壞的(de)(de)能力。3.防護功能：燈(deng)具外(wai)安(an)裝(zhuang)型特別是車燈(deng)，電(dian)源(yuan)結構要(yao)(yao)防水、防潮(chao)，外(wai)殼要(yao)(yao)耐曬。4.驅動(dong)電(dian)源(yuan)的(de)(de)壽(shou)命要(yao)(yao)與LED的(de)(de)壽(shou)命相適配(pei)。5.要(yao)(yao)符合安(an)規和(he)電(dian)磁兼容的(de)(de)要(yao)(yao)求。浙(zhe)江大豪車業始終(zhong)堅(jian)持(chi)以科技進步與創新為(wei)動(dong)力，以質量、信(xin)譽為(wei)基(ji)礎，生(sheng)產高(gao)性(xing)價比產品，提(ti)供(gong)貼心服務！遼(liao)寧(ning)車燈(deng)電(dian)子驅動(dong)批(pi)量定制(zhi)
