大(da)家好(hao)今天來介紹(shao)led燈珠(zhu)串聯的(de)接(jie)法(LED燈珠(zhu)怎么連接(jie)的(de))的(de)問題(ti)，以(yi)下是小編對此(ci)問題(ti)的(de)歸(gui)納整理，來看看吧。 文章目錄列表:
led燈珠怎么連接LED串(chuan)聯為正(zheng)、負(fu)(fu)連接(jie)(jie)，兩端僅(jin)為正(zheng)、負(fu)(fu)，分(fen)別與電(dian)(dian)源的(de)正(zheng)、負(fu)(fu)相(xiang)連接(jie)(jie)，限流(liu)(liu)電(dian)(dian)阻可以在這(zhe)組電(dian)(dian)路的(de)任(ren)何位置串(chuan)聯，當數(shu)量較大時(shi)，采用串(chuan)并聯連接(jie)(jie)，每組串(chuan)聯，并聯組的(de)數(shu)量根據電(dian)(dian)源的(de)額(e)(e)定電(dian)(dian)流(liu)(liu)確定，最并聯的(de)總電(dian)(dian)流(liu)(liu)是電(dian)(dian)流(liu)(liu)不應超過(guo)電(dian)(dian)源的(de)額(e)(e)定耐受電(dian)(dian)流(liu)(liu)。 LED的電(dian)(dian)壓一般在(zai)3V左右(you)，由于LED的電(dian)(dian)壓和(he)(he)電(dian)(dian)流(liu)(liu)特性，在(zai)使用(yong)中必須限制(zhi)電(dian)(dian)流(liu)(liu)，過(guo)大(da)的電(dian)(dian)流(liu)(liu)會(hui)導(dao)致led擊穿和(he)(he)光衰減，為了保(bao)證LED在(zai)正(zheng)常電(dian)(dian)流(liu)(liu)范(fan)圍內工(gong)作(zuo)(zuo)，當(dang)LED與穩壓電(dian)(dian)源(yuan)連(lian)接時(shi)，限流(liu)(liu)電(dian)(dian)阻(zu)必須串聯，限流(liu)(liu)電(dian)(dian)阻(zu)的作(zuo)(zuo)用(yong)是(shi)當(dang)電(dian)(dian)源(yuan)電(dian)(dian)壓過(guo)高或LED溫度過(guo)高時(shi)，主(zhu)要影響(xiang)。 當LED的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)減小(xiao)，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)增大時，與線路相(xiang)連的(de)(de)(de)限流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)增大，從而控(kong)制LED電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)直線上升。在LED串(chuan)聯(lian)電(dian)(dian)(dian)(dian)(dian)(dian)路中，LED串(chuan)聯(lian)次數與LED電(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)(de)乘積必須小(xiao)于穩壓電(dian)(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)最小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)壓，例如，如果電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓為12V DC，則只能有三個(ge)串(chuan)聯(lian)的(de)(de)(de)LED，中間必須串(chuan)聯(lian)一個(ge)150-200歐姆的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)器以限制電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。
led燈珠是怎樣串聯的第一個燈(deng)(deng)珠(zhu)的(de)負(fu)(fu)極(ji)(ji)接(jie)第二(er)個燈(deng)(deng)珠(zhu)的(de)正(zheng)極(ji)(ji)，第二(er)個燈(deng)(deng)珠(zhu)的(de)負(fu)(fu)極(ji)(ji)接(jie)第三(san)個燈(deng)(deng)珠(zhu)的(de)正(zheng)極(ji)(ji)，后邊以此(ci)類推。 led燈珠串聯接法LED串(chuan)聯(lian)方法是(shi)正(zheng)(zheng)負正(zheng)(zheng)負相連，兩(liang)端(duan)(duan)剛好是(shi)一端(duan)(duan)正(zheng)(zheng)極(ji)一端(duan)(duan)負極(ji)分別(bie)接在(zai)電(dian)(dian)(dian)源的正(zheng)(zheng)極(ji)和負極(ji)上，限流(liu)電(dian)(dian)(dian)阻可以串(chuan)在(zai)這組電(dian)(dian)(dian)路的任何位置，如(ru)果數(shu)(shu)量多就(jiu)采用串(chuan)并(bing)聯(lian)組合方式，每(mei)3顆一串(chuan)為一組，再(zai)把每(mei)組并(bing)聯(lian)起來，并(bing)聯(lian)的組數(shu)(shu)根(gen)據電(dian)(dian)(dian)源的額定(ding)(ding)(ding)電(dian)(dian)(dian)流(liu)來決定(ding)(ding)(ding)，最多并(bing)聯(lian)的總電(dian)(dian)(dian)流(liu)不能超(chao)過電(dian)(dian)(dian)源的額定(ding)(ding)(ding)承(cheng)受電(dian)(dian)(dian)流(liu)。 led燈條串聯并聯接線圖串聯(lian)(lian)就(jiu)(jiu)是把LED燈(deng)(deng)珠正(zheng)負腳(jiao)以：正(zheng)負，正(zheng)負連(lian)起來，這就(jiu)(jiu)是串聯(lian)(lian)。并聯(lian)(lian)就(jiu)(jiu)是把LED燈(deng)(deng)珠正(zheng)腳(jiao)都連(lian)在一起，負腳(jiao)連(lian)在一起，根據(ju)驅動電(dian)源(yuan)直流輸出的電(dian)壓，使LED燈(deng)(deng)珠發光。 led燈串聯接法原理LED燈串聯接法是要(yao)根(gen)據其工作電壓(ya)來(lai)決定(ding)的，掌握(wo)輸入電壓(ya)要(yao)等于LED燈串聯后(hou)總工作電壓(ya)即(ji)可。 以上就(jiu)是小編對于led燈(deng)珠(zhu)串聯的(de)(de)(de)接(jie)法(LED燈(deng)珠(zhu)怎么連接(jie)的(de)(de)(de))問題和相關(guan)問題的(de)(de)(de)解答了，希望(wang)對你有(you)用(yong) |
