32v鋰電池可以點亮LED燈珠嗎

當然(ran)可(ke)(ke)以(yi)了，led燈(deng)(deng)(deng)(deng)珠(zhu)很(hen)多額定電(dian)壓是(shi)3.2伏左右，用兩節干電(dian)池基本上就可(ke)(ke)以(yi)了。還有各種各樣的鋰電(dian)池也是(shi)可(ke)(ke)以(yi)給led燈(deng)(deng)(deng)(deng)珠(zhu)供電(dian)的。led燈(deng)(deng)(deng)(deng)珠(zhu)還可(ke)(ke)以(yi)通過串聯并聯形成燈(deng)(deng)(deng)(deng)板那么(me)還能用電(dian)壓較高(gao)的電(dian)池給它(ta)供電(dian)。led燈(deng)(deng)(deng)(deng)珠(zhu)本質上就是(shi)發光二(er)極管，因(yin)此(ci)只(zhi)能用直流電(dian)供電(dian)。

led燈條上的燈珠可以用37v電壓嘛

1W的大功(gong)率LED燈(deng)珠不能直(zhi)接用3.7V鋰電池點亮。

照明用的(de)白光LED燈(deng)(deng)珠(zhu)，其(qi)工作時(shi)(shi)的(de)正向壓降為(wei)3～3.3V，并且(qie)其(qi)正向電阻為(wei)非線性電阻，LED燈(deng)(deng)珠(zhu)在點亮時(shi)(shi)，若沒有(you)限流措施(shi)，只要電源電壓稍微增大一點，流過(guo)燈(deng)(deng)珠(zhu)的(de)正向電流便會劇增，這很容易損(sun)壞LED燈(deng)(deng)珠(zhu)（即使未(wei)壞，也會使其(qi)發光特性變差）。

一(yi)般(ban)LED燈(deng)珠使用時都要加(jia)限流電阻或用恒(heng)流驅動(dong)。對于1W的(de)大功率LED燈(deng)珠，一(yi)般(ban)都是用恒(heng)流驅動(dong)的(de)。

1W LED燈珠能用18650鋰電直接供電嗎

18650鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)與(yu)1WLED的(de)工作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)匹配(pei)的(de)，但鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池剛充滿(man)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)后輸出(chu)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)都(dou)會比(bi)額(e)定(ding)值(zhi)高一些，所以(yi)為(wei)(wei)了使(shi)燈(deng)珠(zhu)穩(wen)定(ding)的(de)工作(zuo)(zuo)，就(jiu)必須在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池與(yu)燈(deng)珠(zhu)之間(jian)加接限(xian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)。在(zai)市售(shou)(shou)的(de)成(cheng)品(pin)燈(deng)中，控制開關大多分為(wei)(wei)四擋(dang)(dang)，第(di)一擋(dang)(dang)時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中串(chuan)入(ru)的(de)限(xian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)為(wei)(wei)200Ω左(zuo)(zuo)右(you)，第(di)二(er)擋(dang)(dang)時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中串(chuan)入(ru)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)為(wei)(wei)100Ω左(zuo)(zuo)右(you)，第(di)三(san)擋(dang)(dang)為(wei)(wei)直通擋(dang)(dang)不接限(xian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)，第(di)四擋(dang)(dang)為(wei)(wei)斷開電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路擋(dang)(dang)，可(ke)以(yi)根據(ju)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)實際情況，選擇適當(dang)的(de)檔位，保(bao)證(zheng)燈(deng)珠(zhu)工作(zuo)(zuo)在(zai)安(an)全的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)范(fan)圍以(yi)內。你可(ke)以(yi)參考市售(shou)(shou)成(cheng)品(pin)燈(deng)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路組成(cheng)方式，在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中串(chuan)入(ru)功率、阻(zu)值(zhi)（建議(yi)選擇1W、100Ω左(zuo)(zuo)右(you)）適合的(de)限(xian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)，就(jiu)可(ke)以(yi)使(shi)LED燈(deng)珠(zhu)安(an)全、正(zheng)常(chang)的(de)工作(zuo)(zuo)了。

LED燈都會用到電池嗎如果要用一般用什么電池

LED是低(di)(di)壓直流下(xia)(xia)工(gong)(gong)作(zuo)的,可(ke)(ke)以不用到電(dian)(dian)池(chi),但一般為了(le)移動和使用方便,都會設計電(dian)(dian)池(chi)在(zai)燈(deng)內部,至于這(zhe)個電(dian)(dian)池(chi),沒有特殊要求,小電(dian)(dian)瓶(ping),普通干電(dian)(dian)池(chi),充電(dian)(dian)電(dian)(dian)池(chi),鋰電(dian)(dian)池(chi)等都可(ke)(ke)以,一般只要大于led的工(gong)(gong)作(zuo)電(dian)(dian)壓(3-3.3v)即可(ke)(ke),這(zhe)也(ye)是為了(le)簡化電(dian)(dian)路,當然更高或(huo)更低(di)(di)的電(dian)(dian)池(chi)電(dian)(dian)壓在(zai)專用線路下(xia)(xia)同樣(yang)能(neng)工(gong)(gong)作(zuo).

大功率led燈珠直接接18650電池

led燈珠直接接18650電池不可以。因(yin)為led燈珠的型號和顏色有很多種，每種的工作電壓(ya)(ya)都不一樣。比(bi)如0805型的led燈珠的工作電壓(ya)(ya)范圍(wei)是(shi)直流3V3.4V，電流為20mA，如果超過它的電壓(ya)(ya)范圍(wei)，燈珠就被燒毀。而18650鋰電池的標稱電壓(ya)(ya)是(shi)3.7V，實際電壓(ya)(ya)會高一點。如果隨意(yi)接一個led燈珠，就會燒毀燈珠。
