大(da)家(jia)好我(wo)是天成照明LED燈(deng)珠(zhu)(zhu)廠家(jia)小編(bian)燈(deng)漂亮今天我(wo)們(men)來(lai)介紹led小燈(deng)珠(zhu)(zhu)電路(lu) led燈(deng)條燈(deng)珠(zhu)(zhu)接線原(yuan)理圖的(de)問題，以下就是燈(deng)漂亮對此問題和相(xiang)關問題的(de)歸納整理,一起來(lai)看看吧。 文章目錄導航: led小燈珠怎么接線 led小燈珠接線路：電源正負(fu)極就是GND和MODE那(nei)兩(liang)條線，現(xian)在(zai)控制器輸出(chu)有四個(ge)孔(kong)(kong)，先看(kan)下那(nei)個(ge)帶十(shi)號的(de)孔(kong)(kong)在(zai)這四個(ge)孔(kong)(kong)的(de)中間還(huan)是邊上，如果在(zai)邊上那(nei)你就把三(san)顆LED的(de)正極連在(zai)一起(qi)接到這個(ge)孔(kong)(kong)上，三(san)顆LED的(de)負(fu)極分別接到另外三(san)個(ge)孔(kong)(kong)。 是否有外(wai)置驅(qu)動電源(適(shi)配器，或者(zhe)叫(jiao)鎮流器)如果(guo)有適(shi)配器，那么(me)隨便拿適(shi)配器的輸出端的兩條線接到燈(deng)上即(ji)(ji)可。如果(guo)第(di)一(yi)次(ci)的接法燈(deng)不亮(liang)，那對換一(yi)下(xia)兩條線，燈(deng)即(ji)(ji)可亮(liang)了。即(ji)(ji)使第(di)一(yi)次(ci)接錯也不會(hui)影響LED燈(deng)。 如果(guo)沒有(you)外置驅動電源，那就不能直(zhi)接接AC220V的市電了。如果(guo)你想判斷正(zheng)負極，也(ye)可以拆開燈(deng)看看，里面一般會有(you)+-標注正(zheng)負極。
220v的g4小led燈珠怎么降壓的 是(shi)可(ke)以的。如果是(shi)直流220伏(fu)(fu)(fu)電(dian)(dian)壓需要安裝一個(ge)電(dian)(dian)路(lu)降壓。輸(shu)220伏(fu)(fu)(fu)接上(shang)電(dian)(dian)路(lu)，通(tong)過電(dian)(dian)路(lu)(通(tong)常用電(dian)(dian)子電(dian)(dian)路(lu)，可(ke)控硅也可(ke))輸(shu)出二(er)路(lu)九伏(fu)(fu)(fu)和六十伏(fu)(fu)(fu)。 如(ru)是交流(liu)220伏(fu)則要用(yong)(yong)變(bian)壓(ya)器降壓(ya)，整流(liu)，濾(lv)波之后(hou)再通過電(dian)子電(dian)路輸出二路直流(liu)電(dian)壓(ya)。如(ru)需(xu)九伏(fu)和六十伏(fu)交流(liu)電(dian)壓(ya)用(yong)(yong)變(bian)壓(ya)器降壓(ya)即可。 led貼片燈珠驅動原理 led貼片燈(deng)珠驅動的(de)原理： 恒流式驅動電源。 a、 恒流(liu)驅動電(dian)路輸出(chu)的電(dian)流(liu)是恒定的，而輸出(chu)的直(zhi)流(liu)電(dian)壓卻隨著負載阻值的大小不同在一定范圍內變化，負載阻值小，輸出(chu)電(dian)壓就低，負載阻值越(yue)大，輸出(chu)電(dian)壓也就越(yue)高。 b、 恒流電路(lu)(lu)(lu)不怕(pa)負(fu)載(zai)短路(lu)(lu)(lu)，但嚴(yan)禁負(fu)載(zai)完全(quan)開路(lu)(lu)(lu)。 c、 恒流驅(qu)動(dong)電路驅(qu)動(dong)LED是較為理(li)想的，但相(xiang)對而(er)言價格較高。 d、 應注(zhu)意所使用最大承受(shou)電(dian)流及電(dian)壓值(zhi)，它限制(zhi)了LED的使用數量。 led小燈珠如何點亮 單只LED燈(deng)珠一般電壓在3-3.5V左右，想(xiang)點亮一個LED燈(deng)，可以給(gei)它的兩端加3-3.2V電壓即可。 一個LED燈珠電路中的電壓電流瓦數的計算 電流并聯(lian)(lian)增(zeng)倍，串聯(lian)(lian)電壓(ya)增(zeng)倍具體值按倍數計算。例如(ru)：一只(zhi)LED 工作電壓(ya)為3.2V 20MA，二個并聯(lian)(lian)工作所需電流為40MA，電壓(ya)不變。 串(chuan)聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)、電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)關系(xi)和(he)并聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)關系(xi)分(fen)別(bie)如(ru)下：1.串(chuan)聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)、電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)關系(xi)：串(chuan)聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)處處相等，電(dian)(dian)(dian)(dian)壓(ya)(ya)倍(bei)減。如(ru)一(yi)只(zhi)LED 工作電(dian)(dian)(dian)(dian)壓(ya)(ya)為3.2V 5A，兩只(zhi)串(chuan)聯(lian)(lian)(lian)后電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)仍為5A，而電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)會(hui)下降6.4V。所以(yi)(yi)2只(zhi)LED燈串(chuan)聯(lian)(lian)(lian)后會(hui)看到燈點不亮，是因為電(dian)(dian)(dian)(dian)壓(ya)(ya)下降了(le)。2.并聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)、電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)(de)關系(xi)：并聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)電(dian)(dian)(dian)(dian)壓(ya)(ya)不變(bian)，電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)倍(bei)增。如(ru)一(yi)只(zhi)LED 工作電(dian)(dian)(dian)(dian)壓(ya)(ya)為3.2V 5A，兩只(zhi)并聯(lian)(lian)(lian)后電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)為10A，而電(dian)(dian)(dian)(dian)路(lu)(lu)上(shang)(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)仍為3.2V。使用(yong)的(de)(de)(de)(de)時(shi)候(hou)用(yong)并聯(lian)(lian)(lian)的(de)(de)(de)(de)接口(kou)12V，充電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)時(shi)候(hou)用(yong)串(chuan)聯(lian)(lian)(lian)的(de)(de)(de)(de)接口(kou)48V，這個想(xiang)法(fa)是可以(yi)(yi)的(de)(de)(de)(de)，但(dan)實(shi)際接線會(hui)較復雜，并且(qie)需要一(yi)個復雜的(de)(de)(de)(de)多位換向開關用(yong)來(lai)轉換充電(dian)(dian)(dian)(dian)和(he)使用(yong)狀態。 以上就是天成小(xiao)編對于led小(xiao)燈珠(zhu)電路 led燈條燈珠(zhu)接線原理圖問題和相(xiang)關(guan)問題的解答了，希(xi)望對你有(you)用 【責(ze)任編輯(ji)：燈漂亮(liang)】 |
