led燈能直接接5v嗎

|ed燈(deng)(deng)使用(yong)直(zhi)(zhi)(zhi)流電(dian)，這(zhe)個5V應當是直(zhi)(zhi)(zhi)流電(dian)壓(ya)，可以直(zhi)(zhi)(zhi)接接，但不(bu)能保(bao)證正常工(gong)作(zuo)。每種不(bu)同(tong)型(xing)號(hao)的(de)led燈(deng)(deng)珠的(de)導通電(dian)壓(ya)和工(gong)作(zuo)電(dian)流，常用(yong)的(de)貼片燈(deng)(deng)珠一般(ban)電(dian)壓(ya)在23V左右，若干燈(deng)(deng)珠組成的(de)燈(deng)(deng)供電(dian)電(dian)壓(ya)也不(bu)同(tong)，所以用(yong)5v供電(dian)，燈(deng)(deng)不(bu)一定能工(gong)作(zuo)(正常發亮(liang))，常見的(de)小(xiao)夜燈(deng)(deng)基本上都(dou)是使用(yong)5V充電(dian)，這(zhe)種燈(deng)(deng)也可用(yong)5V充電(dian)頭直(zhi)(zhi)(zhi)接點亮(liang)

對(dui)于單顆燈珠直(zhi)接接5V電源(yuan)(如手機充電器(qi))，也有可(ke)能燒壞。

20顆led燈珠5v是多少瓦

LED燈(deng)(deng)(deng)珠有各類不同規格，主要元件參數是(shi)導(dao)通(tong)電(dian)(dian)壓和充許通(tong)過(guo)的(de)電(dian)(dian)流(liu)。有導(dao)通(tong)電(dian)(dian)壓最少為2伏，電(dian)(dian)流(liu)在(zai)十(shi)幾毫安。5Ⅴ下只能串聯(lian)兩個(ge)。20顆燈(deng)(deng)(deng)珠，可用10顆并聯(lian)，兩個(ge)并聯(lian)的(de)再串接于5V電(dian)(dian)路中，按每(mei)個(ge)電(dian)(dian)流(liu)設定(ding)的(de)電(dian)(dian)流(liu)算出總電(dian)(dian)流(liu)，乘上(shang)5V就是(shi)這個(ge)燈(deng)(deng)(deng)的(de)功率瓦數。因燈(deng)(deng)(deng)珠上(shang)電(dian)(dian)流(liu)大小(xiao)影(ying)響亮度(du)和壽命，必須要看燈(deng)(deng)(deng)珠的(de)設定(ding)大小(xiao)。

led燈珠怎么改成5v

led燈(deng)(deng)珠(zhu)是(shi)(shi)半導(dao)(dao)體發(fa)光元件，它(ta)的(de)(de)使用(yong)電(dian)(dian)壓(ya)(ya)就是(shi)(shi)燈(deng)(deng)珠(zhu)正向(xiang)(xiang)(xiang)導(dao)(dao)通(tong)電(dian)(dian)壓(ya)(ya)，不(bu)同半導(dao)(dao)體材(cai)料做的(de)(de)燈(deng)(deng)珠(zhu)，它(ta)的(de)(de)正向(xiang)(xiang)(xiang)導(dao)(dao)通(tong)電(dian)(dian)壓(ya)(ya)是(shi)(shi)不(bu)一樣的(de)(de)，燈(deng)(deng)珠(zhu)一經做成，它(ta)的(de)(de)正向(xiang)(xiang)(xiang)導(dao)(dao)通(tong)電(dian)(dian)壓(ya)(ya)是(shi)(shi)不(bu)可改變的(de)(de)。一般燈(deng)(deng)珠(zhu)導(dao)(dao)通(tong)電(dian)(dian)壓(ya)(ya)為23V左(zuo)。如果說(shuo)的(de)(de)是(shi)(shi)用(yong)5V為燈(deng)(deng)珠(zhu)供電(dian)(dian)，可在(zai)5V電(dian)(dian)源輸出端串接(jie)一個電(dian)(dian)阻加以分壓(ya)(ya)和限流(liu)。

led燈珠18w用五伏電壓能亮嗎

不知道(dao)你(ni)這(zhe)個led燈(deng)珠(zhu)(zhu)(zhu)額(e)(e)定電(dian)(dian)壓(ya)是多少，是一(yi)顆功(gong)率就有(you)1.8w嗎據我所知很(hen)多燈(deng)珠(zhu)(zhu)(zhu)的(de)額(e)(e)定電(dian)(dian)壓(ya)都是三點(dian)幾伏(fu)的(de)，這(zhe)樣的(de)燈(deng)珠(zhu)(zhu)(zhu)如果(guo)兩顆串聯起來(lai)用五(wu)伏(fu)電(dian)(dian)壓(ya)是可(ke)以(yi)(yi)點(dian)亮(liang)的(de)，但(dan)功(gong)率就不能滿(man)負(fu)荷了。當然，點(dian)亮(liang)燈(deng)珠(zhu)(zhu)(zhu)跟燈(deng)珠(zhu)(zhu)(zhu)正常工(gong)作還是有(you)差別(bie)的(de)，燈(deng)珠(zhu)(zhu)(zhu)只有(you)在額(e)(e)定電(dian)(dian)壓(ya)和(he)電(dian)(dian)流下才能正常工(gong)作但(dan)點(dian)亮(liang)燈(deng)珠(zhu)(zhu)(zhu)電(dian)(dian)壓(ya)和(he)電(dian)(dian)流都可(ke)以(yi)(yi)小一(yi)點(dian)。

5v的led燈珠能用12v的變壓器嗎

12Ⅴ變壓器(qi)不能(neng)直接為5Vled燈(deng)珠(zhu)(zhu)供電(dian)(dian)。在釆取(qu)一定措施后(hou)(hou)(hou)是可(ke)以的。5V的led燈(deng)珠(zhu)(zhu)其導通電(dian)(dian)壓為5V，達到(dao)(dao)5V后(hou)(hou)(hou)燈(deng)珠(zhu)(zhu)可(ke)點(dian)亮，其亮度與(yu)通過的電(dian)(dian)流有關，與(yu)電(dian)(dian)壓無關了。但是電(dian)(dian)壓超過5V很(hen)多(duo)會(hui)燒(shao)壞燈(deng)珠(zhu)(zhu)。12V的變壓器(qi)為5V燈(deng)珠(zhu)(zhu)供電(dian)(dian)應(ying)降壓，即12V降到(dao)(dao)5V后(hou)(hou)(hou)才可(ke)。另外還應(ying)考慮燈(deng)珠(zhu)(zhu)額定電(dian)(dian)流值，電(dian)(dian)流過大(da)也會(hui)燒(shao)壞燈(deng)珠(zhu)(zhu)。
