18650的電池用多大的燈珠最亮

18650的電池用3.7v的燈珠最亮。

18650鋰電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)與1WLED的(de)工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是匹配的(de)，但鋰電(dian)(dian)(dian)(dian)(dian)池(chi)剛充滿電(dian)(dian)(dian)(dian)(dian)后輸(shu)出的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)和(he)電(dian)(dian)(dian)(dian)(dian)流(liu)都會比額(e)定(ding)值高(gao)一(yi)些，所以(yi)為(wei)(wei)了使燈(deng)珠穩定(ding)的(de)工(gong)作(zuo)，就必須在電(dian)(dian)(dian)(dian)(dian)池(chi)與燈(deng)珠之間(jian)加接限流(liu)電(dian)(dian)(dian)(dian)(dian)阻。在市售的(de)成(cheng)(cheng)品燈(deng)中，控制開關大多分為(wei)(wei)四擋(dang)，第一(yi)擋(dang)時電(dian)(dian)(dian)(dian)(dian)路中串入(ru)的(de)限流(liu)電(dian)(dian)(dian)(dian)(dian)阻為(wei)(wei)200Ω左右(you)，第二擋(dang)時電(dian)(dian)(dian)(dian)(dian)路中串入(ru)的(de)電(dian)(dian)(dian)(dian)(dian)阻為(wei)(wei)100Ω左右(you)，第三(san)擋(dang)為(wei)(wei)直通擋(dang)不接限流(liu)電(dian)(dian)(dian)(dian)(dian)阻，第四擋(dang)為(wei)(wei)斷開電(dian)(dian)(dian)(dian)(dian)路擋(dang)，可以(yi)根據電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)實際情況，選擇適(shi)當的(de)檔位，保證燈(deng)珠工(gong)作(zuo)在安(an)全的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)范圍(wei)以(yi)內。你可以(yi)參考市售成(cheng)(cheng)品燈(deng)的(de)電(dian)(dian)(dian)(dian)(dian)路組(zu)成(cheng)(cheng)方式，在電(dian)(dian)(dian)(dian)(dian)路中串入(ru)功率、阻值（建(jian)議選擇1W、100Ω左右(you)）適(shi)合的(de)限流(liu)電(dian)(dian)(dian)(dian)(dian)阻，就可以(yi)使LED燈(deng)珠安(an)全、正常的(de)工(gong)作(zuo)了。

18650電池能直接接led燈珠亮多長時間

可(ke)以(yi)亮(liang)2個(ge)多小(xiao)時(shi)，18650鋰電(dian)(dian)池2200毫安時(shi)就(jiu)是一節三(san)元18650鋰電(dian)(dian)，功(gong)率(lv)是8.14w，如此小(xiao)功(gong)率(lv)的電(dian)(dian)池可(ke)以(yi)點亮(liang)3w的LED燈2.5小(xiao)時(shi)。

18650鋰電池(chi)(chi)的使用壽命都只在三年五年。鋰電池(chi)(chi)一(yi)般能夠充放300－500次。

最好對鋰電(dian)(dian)池(chi)進行(xing)部分放電(dian)(dian)，而(er)不(bu)是放電(dian)(dian)，并且要盡量(liang)避免(mian)經常的放電(dian)(dian)。

18650燈珠 最亮的多少W

一節18650鋰電池(chi)，如果是三(san)元電池(chi)，功率為3.7x2.5=9.25w，可以點(dian)亮9w的燈泡。

led燈珠直接接18650電池可以嗎

led燈(deng)(deng)珠(zhu)直接接18650電(dian)(dian)池(chi)不(bu)可(ke)以。因為led燈(deng)(deng)珠(zhu)的(de)(de)(de)型(xing)號(hao)和顏(yan)色有很多(duo)種，每種的(de)(de)(de)工作(zuo)電(dian)(dian)壓(ya)都不(bu)一(yi)(yi)樣(yang)。比如0805型(xing)的(de)(de)(de)led燈(deng)(deng)珠(zhu)的(de)(de)(de)工作(zuo)電(dian)(dian)壓(ya)范圍(wei)是直流3V3.4V，電(dian)(dian)流為20mA，如果超過它的(de)(de)(de)電(dian)(dian)壓(ya)范圍(wei)，燈(deng)(deng)珠(zhu)就(jiu)被燒毀(hui)。而18650鋰電(dian)(dian)池(chi)的(de)(de)(de)標稱電(dian)(dian)壓(ya)是3.7V，實(shi)際電(dian)(dian)壓(ya)會高一(yi)(yi)點。如果隨意接一(yi)(yi)個led燈(deng)(deng)珠(zhu)，就(jiu)會燒毀(hui)燈(deng)(deng)珠(zhu)。

1500毫安的18650電池帶3瓦的led燈珠能亮多久

首(shou)先(xian)的(de)一個(ge)條(tiao)件就是3W燈(deng)的(de)額定工作電(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)壓相匹配。1500毫安電(dian)(dian)(dian)(dian)池(chi)，其(qi)容量(liang)等(deng)于(yu)1500毫安時(shi)，等(deng)于(yu)1.5安時(shi)，如果是18650鋰電(dian)(dian)(dian)(dian)池(chi)，電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓是3.7伏，那(nei)么電(dian)(dian)(dian)(dian)池(chi)的(de)存電(dian)(dian)(dian)(dian)量(liang)等(deng)于(yu)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓乘(cheng)以電(dian)(dian)(dian)(dian)池(chi)容量(liang)，W=UQ=3.7V*1.5ah=5.55Wh。3W燈(deng)使用時(shi)間是5.55Wh/3W=1.85h（小(xiao)時(shi)）。
