LED燈三條線的接線方法(fa)要先分(fen)辨線的類型，再根據不(bu)同(tong)情(qing)況連接電源(yuan)和控制器。

LED燈(deng)三條(tiao)線(xian)(xian)(xian)(xian)通常分(fen)別是(shi)正極(ji)(ji)線(xian)(xian)(xian)(xian)、負(fu)極(ji)(ji)線(xian)(xian)(xian)(xian)和控(kong)制(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)。分(fen)辨線(xian)(xian)(xian)(xian)的顏色很(hen)重要(yao)，一(yi)般紅線(xian)(xian)(xian)(xian)為(wei)正極(ji)(ji)線(xian)(xian)(xian)(xian)，黑線(xian)(xian)(xian)(xian)為(wei)負(fu)極(ji)(ji)線(xian)(xian)(xian)(xian) ，黃線(xian)(xian)(xian)(xian)等可能是(shi)控(kong)制(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)。確定220v交(jiao)流(liu)電源(yuan)(yuan)后(hou)，要(yao)在(zai)操作(zuo)前關閉電源(yuan)(yuan)以保障安全(quan)。用(yong)萬用(yong)表歐姆檔測量(liang)可初步判(pan)斷燈(deng)是(shi)否正常。接(jie)(jie)(jie)地線(xian)(xian)(xian)(xian)不能接(jie)(jie)(jie)在(zai)正負(fu)極(ji)(ji)線(xian)(xian)(xian)(xian)上(shang)，條(tiao)件(jian)允許時(shi)應(ying)接(jie)(jie)(jie)在(zai)燈(deng)具上(shang)對應(ying)的接(jie)(jie)(jie)地位置。若使用(yong)直接(jie)(jie)(jie)接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)法，正接(jie)(jie)(jie)正、負(fu)接(jie)(jie)(jie)負(fu)，適合簡單無(wu)特殊控(kong)制(zhi)(zhi)(zhi)需求的情況。串聯(lian)接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)用(yong)于(yu)連接(jie)(jie)(jie)多(duo)(duo)個LED燈(deng)，將正、負(fu)極(ji)(ji)線(xian)(xian)(xian)(xian)依次相(xiang)(xiang)連后(hou)再接(jie)(jie)(jie)電源(yuan)(yuan)。并聯(lian)接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)能同時(shi)控(kong)制(zhi)(zhi)(zhi)多(duo)(duo)個LED燈(deng)，正、負(fu)極(ji)(ji)線(xian)(xian)(xian)(xian)分(fen)別相(xiang)(xiang)連接(jie)(jie)(jie)電源(yuan)(yuan)，控(kong)制(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)接(jie)(jie)(jie)控(kong)制(zhi)(zhi)(zhi)器(qi)。使用(yong)驅動(dong)器(qi)接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)時(shi)，驅動(dong)器(qi)正、負(fu)極(ji)(ji)接(jie)(jie)(jie)LED燈(deng)正、負(fu)極(ji)(ji)，控(kong)制(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)接(jie)(jie)(jie)驅動(dong)器(qi)。

接線時(shi)務必仔細，遵循正確方法，不確定時(shi)查看說明(ming)書。這不僅關乎(hu)LED燈(deng)能否正常(chang)使用，更關系到用電安全，不熟悉(xi)操(cao)作(zuo)的話最好請專業人(ren)士幫忙 。
