大家好(hao)我(wo)(wo)是小編沁夢今天(tian)我(wo)(wo)們來介紹如(ru)何用電(dian)池接(jie)(jie)led燈(deng)珠(zhu) led燈(deng)珠(zhu)怎樣接(jie)(jie)12伏(fu)電(dian)源的問(wen)題(ti)(ti)，以下就是沁夢對此問(wen)題(ti)(ti)和相關問(wen)題(ti)(ti)的歸納(na)整(zheng)理(li),一(yi)起來看看吧。 文章目錄導航: led燈珠可以直連電池嗎 大功率led燈(deng)珠可以自制手電(dian)，直接(jie)連接(jie)在電(dian)池上不(bu)(bu)可以，它的電(dian)壓3.2v-3.4v，電(dian)流0.3A，不(bu)(bu)過有(you)0.1A也可以正常發光(guang)，最好使用手機(ji)電(dian)池3.7v串聯(lian)一個10歐（1w）電(dian)阻就可以直接(jie)接(jie)燈(deng)珠了，如果找不(bu)(bu)到(dao)電(dian)阻或(huo)者安裝不(bu)(bu)方便(bian)，可以用300w以上電(dian)爐絲(si)截取10歐代(dai)替，只(zhi)要電(dian)路連接(jie)正確(que)就ok
一個74伏的電池怎么接LED燈珠的問題 最簡單的(de)(de)(de)方法就是(shi)兩顆(ke)(ke)燈(deng)珠串(chuan)聯再用(yong)這樣燈(deng)串(chuan)并聯，兩顆(ke)(ke)燈(deng)珠串(chuan)聯電壓大概是(shi)6.6伏左右(you)，再串(chuan)聯一(yi)(yi)顆(ke)(ke)電阻分(fen)一(yi)(yi)伏左右(you)的(de)(de)(de)電壓。但電池電壓會隨著放電的(de)(de)(de)進行遂步降低，用(yong)電池電壓直接給led燈(deng)珠供(gong)電也是(shi)不合適的(de)(de)(de)。最好(hao)的(de)(de)(de)辦法是(shi)根(gen)據led燈(deng)珠的(de)(de)(de)功率和額定電流選(xuan)擇一(yi)(yi)個合適的(de)(de)(de)恒流電源適配器。led燈(deng)珠就是(shi)發光二(er)極管，根(gen)據二(er)極管的(de)(de)(de)伏安特性(xing)曲線可(ke)知它是(shi)適宜于恒流驅動的(de)(de)(de)。 led燈珠怎么用電池供電 led燈(deng)珠(zhu)怎么用(yong)充電(dian)器的(de)(de)電(dian)壓一般是(shi)4.7-5.6V，LED燈(deng)珠(zhu)額定電(dian)壓一般3-3.6V，科瑞(rui)的(de)(de)電(dian)壓偏低，一般在(zai)3.1V左(zuo)右，如(ru)果不(bu)加(jia)限流，直接接到5V上去，電(dian)流會很(hen)大，燈(deng)珠(zhu)用(yong)不(bu)了多久就會燒壞。剛接上可以點亮，而(er)且很(hen)亮，但點的(de)(de)時間長了，燈(deng)珠(zhu)很(hen)快(kuai)就會被(bei)燒壞。 不可(ke)(ke)以(yi)。照明用(yong)(yong)高亮度LED的(de)工作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓大(da)約是3.2V左右(you)，工作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在100mA左右(you)，如果(guo)你直接(jie)(jie)使用(yong)(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)連接(jie)(jie)的(de)話，將會很快燒毀LED。二、不可(ke)(ke)以(yi)。原因同上三、不一定。如果(guo)是使用(yong)(yong)變壓器(qi)(qi)進行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)或者是開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路進行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，那么基本上可(ke)(ke)以(yi)在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)同時使用(yong)(yong)LED，但是對于使用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)限流(liu)的(de)簡(jian)易恒流(liu)式(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路（就是常見的(de)廉價的(de)那種(zhong)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)式(shi)手電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)筒內部的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路），就絕(jue)對不可(ke)(ke)以(yi)在開(kai)燈的(de)情況下(xia)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。 贊一下 led燈珠可以直連電池嗎 大功率led燈珠可(ke)以(yi)(yi)自制手電(dian)(dian)(dian)，直(zhi)接(jie)連接(jie)在(zai)電(dian)(dian)(dian)池上(shang)不(bu)可(ke)以(yi)(yi)，它(ta)的電(dian)(dian)(dian)壓3.2v-3.4v，電(dian)(dian)(dian)流(liu)0.3A，不(bu)過有(you)0.1A也可(ke)以(yi)(yi)正常發(fa)光，最好使用手機電(dian)(dian)(dian)池3.7v串聯一個10歐(ou)（1w）電(dian)(dian)(dian)阻(zu)就可(ke)以(yi)(yi)直(zhi)接(jie)接(jie)燈珠了，如(ru)果找不(bu)到電(dian)(dian)(dian)阻(zu)或(huo)者(zhe)安裝不(bu)方便，可(ke)以(yi)(yi)用300w以(yi)(yi)上(shang)電(dian)(dian)(dian)爐絲截取10歐(ou)代(dai)替，只要電(dian)(dian)(dian)路連接(jie)正確就ok 如何把led燈珠接到蓄電池上面 控(kong)制每個(ge)led燈珠電流在其額定電流內(nei)，串個(ge)適當的電阻，按正負極正確接到蓄電池正負極上即(ji)可。 以上就是天成小編對(dui)于(yu)如何用電(dian)池接led燈(deng)珠 led燈(deng)珠怎樣接12伏(fu)電(dian)源問題和相關問題的解答了，希望對(dui)你有(you)用 【責任編輯：沁夢(meng)】 |
