18650電池能直接接led燈珠亮多長時間

60個(ge)左右(you)的白光高亮 Φ3的led并聯(lian)(lian),以(yi)每個(ge)led30mA計算，60個(ge)應該是1.8A/3.6V約(yue)為(wei)7W左右(you)，可(ke)以(yi)不(bu)串聯(lian)(lian)電阻(zu)，3.7v 2600mA.如果一(yi)直工作(zuo)，大約(yue)可(ke)以(yi)工作(zuo)80分鐘(zhong)以(yi)上（電池充滿(man)電且性能優良），如果用(yong)兩節電池，那工作(zuo)的時(shi)間應是一(yi)節電池的兩倍。

18650led燈珠怎么接

18650鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)與1WLED的(de)(de)工(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)是匹配的(de)(de)，但鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)剛充滿電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后輸出的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流都(dou)會比額定(ding)值高一些，所以(yi)(yi)(yi)為了使燈珠(zhu)(zhu)穩定(ding)的(de)(de)工(gong)(gong)作(zuo)(zuo)，就必須(xu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)與燈珠(zhu)(zhu)之間加接(jie)限流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)。 在(zai)市(shi)售的(de)(de)成品(pin)(pin)燈中，控制(zhi)開關大多分為四擋，第一擋時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中串(chuan)(chuan)入(ru)的(de)(de)限流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)為200Ω左(zuo)右，第二(er)擋時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中串(chuan)(chuan)入(ru)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)為100Ω左(zuo)右，第三擋為直通擋不接(jie)限流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，第四擋為斷開電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)擋，可(ke)以(yi)(yi)(yi)根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)實際情況，選擇(ze)適(shi)當的(de)(de)檔(dang)位，保證燈珠(zhu)(zhu)工(gong)(gong)作(zuo)(zuo)在(zai)安全(quan)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流范圍(wei)以(yi)(yi)(yi)內。 你可(ke)以(yi)(yi)(yi)參考(kao)市(shi)售成品(pin)(pin)燈的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)組成方(fang)式，在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中串(chuan)(chuan)入(ru)功率(lv)、阻(zu)(zu)值（建議選擇(ze)1W、100Ω左(zuo)右）適(shi)合的(de)(de)限流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，就可(ke)以(yi)(yi)(yi)使LED燈珠(zhu)(zhu)安全(quan)、正常(chang)的(de)(de)工(gong)(gong)作(zuo)(zuo)了。

led燈珠直接接18650電池可以嗎

led燈珠(zhu)(zhu)(zhu)直(zhi)(zhi)接(jie)接(jie)18650電(dian)池(chi)不可以(yi)。因為led燈珠(zhu)(zhu)(zhu)的型號和顏色(se)有很多(duo)種(zhong)，每種(zhong)的工作電(dian)壓(ya)都不一樣。比如0805型的led燈珠(zhu)(zhu)(zhu)的工作電(dian)壓(ya)范圍是直(zhi)(zhi)流(liu)3V3.4V，電(dian)流(liu)為20mA，如果超(chao)過它(ta)的電(dian)壓(ya)范圍，燈珠(zhu)(zhu)(zhu)就被燒毀。而18650鋰電(dian)池(chi)的標稱電(dian)壓(ya)是3.7V，實際電(dian)壓(ya)會(hui)高(gao)一點。如果隨意接(jie)一個led燈珠(zhu)(zhu)(zhu)，就會(hui)燒毀燈珠(zhu)(zhu)(zhu)。

18650能直接接led燈嗎

18650是(shi)3.7v2200毫安，led燈珠3.7v1w，直(zhi)接接要加(jia)上鋁(lv)制散熱(re)板。

3w37vled燈珠沒有驅動板直接接一節18650電源能亮嗎

能亮(liang)，但燈珠(zhu)的(de)電流有800多毫安(an)估計電池堅(jian)持不了多久，當電池電壓(ya)降低(di)以(yi)后燈珠(zhu)的(de)亮(liang)度也會慢慢降低(di)了。led燈珠(zhu)實際上(shang)就是發(fa)(fa)光二極管，根據二極管的(de)伏安(an)特性曲線可(ke)知適宜于恒流驅動(dong)(dong)。選用(yong)恒流驅動(dong)(dong)器可(ke)以(yi)保證電池電壓(ya)在一定的(de)范圍(wei)之內變動(dong)(dong)時燈的(de)亮(liang)度不發(fa)(fa)生變化。

以(yi)上就是(shi)天成小編(bian)對于(yu)led燈珠接18650 led燈珠直(zhi)接18650電池問(wen)題和相(xiang)關問(wen)題的解答了，希望對你有用 【責任編(bian)輯(ji)：榮姐】
