大家好今天來(lai)介紹(shao)led小(xiao)燈(deng)珠(zhu)接(jie)(jie)電池(led燈(deng)珠(zhu)直接(jie)(jie)接(jie)(jie)12v電瓶可(ke)以嗎)的(de)問(wen)題(ti)，以下是(shi)小(xiao)編對此問(wen)題(ti)的(de)歸納(na)整理，來(lai)看看吧。 文章目錄列表:led燈珠怎么接12v電瓶首先(xian)要明確是(shi)10w大功(gong)率led燈珠，還是(shi)10w大功(gong)率led燈led燈珠和led燈是(shi)不同的(de)，接電瓶的(de)方法也不相同。 led燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)就是led發光二極管，10w如(ru)(ru)(ru)此大功(gong)率的(de)led燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)目前還不可能做到。如(ru)(ru)(ru)果真是10w大功(gong)率led燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)，還要知道燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)額定電(dian)(dian)(dian)壓參(can)數。在參(can)數不明的(de)情(qing)況下(xia)，估計單個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)額定電(dian)(dian)(dian)壓為3.5--4.5v，可以(yi)將4個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)串(chuan)(chuan)聯再(zai)連接(jie)12v電(dian)(dian)(dian)瓶。接(jie)線方(fang)法是：電(dian)(dian)(dian)瓶的(de)正(zheng)(zheng)極接(jie)第一(yi)(yi)個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)正(zheng)(zheng)極，第一(yi)(yi)個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)負(fu)(fu)極又接(jie)第二個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)正(zheng)(zheng)極，第二個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)負(fu)(fu)極再(zai)接(jie)第三個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)正(zheng)(zheng)極，如(ru)(ru)(ru)此類推(tui)，直至最(zui)后(hou)一(yi)(yi)個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)的(de)負(fu)(fu)極接(jie)電(dian)(dian)(dian)瓶的(de)負(fu)(fu)極。這時燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)就亮(liang)了。如(ru)(ru)(ru)果發現燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)發光暗淡，可改(gai)為3個(ge)(ge)燈(deng)(deng)(deng)(deng)珠(zhu)(zhu)(zhu)(zhu)(zhu)串(chuan)(chuan)聯。 如果是led燈(deng)(deng)(deng)(deng)，或(huo)led燈(deng)(deng)(deng)(deng)泡，也要知道其電壓參數。一般(ban)led燈(deng)(deng)(deng)(deng)或(huo)燈(deng)(deng)(deng)(deng)泡是由許多單個(ge)燈(deng)(deng)(deng)(deng)珠和(he)驅動芯片集成的產(chan)品，接(jie)法相(xiang)對簡單，只要其額定電壓是12v直(zhi)流(liu)，直(zhi)接(jie)和(he)12v電瓶的同極(ji)連接(jie)就(jiu)可以了(le)。但(dan)10w12v的led燈(deng)(deng)(deng)(deng)，其電流(liu)可能達到10/12=833ma，電瓶的容量要達到10ah，才能供電10小時以上。
led燈珠可以直連電池嗎大功率led燈(deng)珠(zhu)可(ke)以自制手電(dian)(dian)(dian)(dian)，直(zhi)接(jie)連(lian)接(jie)在電(dian)(dian)(dian)(dian)池上不可(ke)以，它的電(dian)(dian)(dian)(dian)壓(ya)3.2v-3.4v，電(dian)(dian)(dian)(dian)流(liu)0.3A，不過有0.1A也可(ke)以正常發光(guang)，最好使用(yong)手機電(dian)(dian)(dian)(dian)池3.7v串聯一個10歐(ou)(ou)（1w）電(dian)(dian)(dian)(dian)阻就可(ke)以直(zhi)接(jie)接(jie)燈(deng)珠(zhu)了，如(ru)果找不到(dao)電(dian)(dian)(dian)(dian)阻或者安裝(zhuang)不方便，可(ke)以用(yong)300w以上電(dian)(dian)(dian)(dian)爐絲截取(qu)10歐(ou)(ou)代替，只要電(dian)(dian)(dian)(dian)路(lu)連(lian)接(jie)正確就ok 強光手電筒燈珠能直接接電池嗎不可以(yi)，通常單獨的LED燈是不能直接(jie)接(jie)電源(yuan)的,需要匹配相符的電源(yuan)來供電,如恒(heng)流驅動電源(yuan)。 不能，因為當電池(chi)電量接近耗(hao)盡時，電池(chi)的等效內阻較大，如果嵌入式系統(tong)所需的電流較小(xiao)，則電池(chi)內阻上的損(sun)耗(hao)小(xiao)，嵌入式系統(tong)得(de)到的電壓就更容易滿(man)足其正常(chang)工作的值(zhi)。使系統(tong)在低電量的情況下(xia)也能順利啟動運行。 因為如果電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)直驅(qu)LED的(de)(de)(de)話，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)輸出的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)(dian)(dian)流會成(cheng)(cheng)逐漸減小的(de)(de)(de)趨勢，這樣(yang)會造成(cheng)(cheng)強光的(de)(de)(de)不穩定(ding)(ding)性。增(zeng)加了驅(qu)動(dong)板，就會自動(dong)調(diao)節(jie)，使輸出的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)一直穩定(ding)(ding)。電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)存電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)原理(li)是(shi)是(shi)根據(ju)某些化學反應制成(cheng)(cheng)的(de)(de)(de)，隨著(zhu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)使用，其內部(bu)的(de)(de)(de)化學反應也相應的(de)(de)(de)減弱(ruo)，這就造成(cheng)(cheng)的(de)(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)不穩定(ding)(ding)性。 led燈珠怎么用電池供電led燈(deng)珠(zhu)怎么(me)用充(chong)電(dian)(dian)器的(de)(de)電(dian)(dian)壓(ya)一(yi)般是4.7-5.6V，LED燈(deng)珠(zhu)額定電(dian)(dian)壓(ya)一(yi)般3-3.6V，科瑞的(de)(de)電(dian)(dian)壓(ya)偏(pian)低，一(yi)般在3.1V左右(you)，如果不(bu)加(jia)限(xian)流(liu)，直接(jie)接(jie)到(dao)5V上去，電(dian)(dian)流(liu)會很(hen)大，燈(deng)珠(zhu)用不(bu)了多久就(jiu)會燒壞。剛(gang)接(jie)上可(ke)以點亮(liang)，而(er)且很(hen)亮(liang)，但點的(de)(de)時(shi)間長了，燈(deng)珠(zhu)很(hen)快就(jiu)會被燒壞。 不(bu)(bu)可以。照明(ming)用(yong)高亮度LED的工作(zuo)(zuo)電(dian)(dian)(dian)壓(ya)大約是(shi)3.2V左(zuo)右，工作(zuo)(zuo)電(dian)(dian)(dian)流(liu)在100mA左(zuo)右，如(ru)果你直接(jie)使用(yong)充(chong)(chong)(chong)電(dian)(dian)(dian)器連接(jie)的話，將會很快燒(shao)毀LED。二、不(bu)(bu)可以。原因同(tong)上(shang)三(san)、不(bu)(bu)一定。如(ru)果是(shi)使用(yong)變壓(ya)器進行充(chong)(chong)(chong)電(dian)(dian)(dian)或者是(shi)開關電(dian)(dian)(dian)源電(dian)(dian)(dian)路(lu)(lu)進行充(chong)(chong)(chong)電(dian)(dian)(dian)，那么基本上(shang)可以在充(chong)(chong)(chong)電(dian)(dian)(dian)的同(tong)時使用(yong)LED，但(dan)是(shi)對于使用(yong)電(dian)(dian)(dian)容器限流(liu)的簡易恒流(liu)式充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路(lu)(lu)（就(jiu)是(shi)常(chang)見的廉價的那種充(chong)(chong)(chong)電(dian)(dian)(dian)式手電(dian)(dian)(dian)筒內部的充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路(lu)(lu)），就(jiu)絕對不(bu)(bu)可以在開燈的情況下充(chong)(chong)(chong)電(dian)(dian)(dian)。 贊一下 以上就是小編對于led小燈(deng)珠接(jie)電池(led燈(deng)珠直接(jie)接(jie)12v電瓶(ping)可以嗎)問題和相關(guan)問題的(de)解答了，希望對你有用(yong) |
