一、手搖手電筒原理是什么
手電筒中(zhong)沒(mei)有電池(chi),在晃(huang)動(dong)手(shou)電筒時(shi),手(shou)電筒中(zhong)的永磁體(ti)(ti)在線(xian)圈中(zhong)運動(dong),運動(dong)是相(xiang)對(dui)而(er)言的,相(xiang)對(dui)于(yu)永磁體(ti)(ti)而(er)言,線(xian)圈在做(zuo)切(qie)割磁感線(xian)運動(dong),所以會產生感應電流,電流通過燈泡,燈泡就會發(fa)光(guang)。
二、手搖手電筒原理圖
手搖手電(dian)(dian)(dian)筒(tong)(tong)是一種(zhong)利用(yong)大功(gong)(gong)率的(de)(de)三(san)相交流發電(dian)(dian)(dian)機進行手搖發電(dian)(dian)(dian)的(de)(de)設備,利用(yong)此原理產生的(de)(de)電(dian)(dian)(dian)能可(ke)(ke)以(yi)通(tong)過(guo)開關電(dian)(dian)(dian)源來對手電(dian)(dian)(dian)筒(tong)(tong)的(de)(de)電(dian)(dian)(dian)路系統進行內置充電(dian)(dian)(dian)。此種(zhong)手電(dian)(dian)(dian)筒(tong)(tong)可(ke)(ke)以(yi)在較(jiao)(jiao)為緊急的(de)(de)情況下使(shi)用(yong)不僅具(ju)有(you)(you)較(jiao)(jiao)為便(bian)于攜(xie)帶的(de)(de)作用(yong)還具(ju)有(you)(you)結構簡單的(de)(de)功(gong)(gong)能。在一些特(te)殊(shu)的(de)(de)情況下可(ke)(ke)以(yi)進行突然(ran)性(xing)的(de)(de)照明使(shi)用(yong),不僅如此手搖電(dian)(dian)(dian)筒(tong)(tong)的(de)(de)發電(dian)(dian)(dian)量還可(ke)(ke)以(yi)在一定(ding)程度上用(yong)作手電(dian)(dian)(dian)筒(tong)(tong)的(de)(de)備用(yong)電(dian)(dian)(dian)量。
該手(shou)搖動式自(zi)發(fa)電(dian)(dian)手(shou)電(dian)(dian)筒原理圖(tu)(tu)如(ru)(ru)圖(tu)(tu)所示(shi)。其結(jie)構示(shi)意圖(tu)(tu)如(ru)(ru)圖(tu)(tu)2所示(shi)。在使(shi)用電(dian)(dian)筒時(shi),搖動電(dian)(dian)筒使(shi)它的磁鐵7上(shang)下(xia)移動,通(tong)過線(xian)圈6即產(chan)生電(dian)(dian)能,再經圖(tu)(tu)2中的D1-D4整(zheng)流,C1貯(zhu)能向電(dian)(dian)池CR2032充電(dian)(dian)通(tong)過開關控制使(shi)發(fa)白光(guang)二極管(guan)發(fa)光(guang)而實(shi)現(xian)自(zi)發(fa)電(dian)(dian)的功能。

三、 手搖手電筒內部結構是怎么樣的
在圖中,1為(wei)圓筒(tong)形的(de)(de)塑(su)(su)料(liao)骨(gu)架(jia)(jia)。2為(wei)發白(bai)光二(er)極管3為(wei)電(dian)(dian)路(lu)板(ban)。4為(wei)用(yong)銅片制作的(de)(de)開關。5為(wei)予留(liu)的(de)(de)CR2032電(dian)(dian)池位(wei)置。6為(wei)空芯(xin)線圈(quan),電(dian)(dian)感量約33mh,線徑約φ.2mm。7為(wei)強(qiang)力磁(ci)鐵,應(ying)使它能在圓筒(tong)內順(shun)利的(de)(de)上(shang)(shang)下(xia)移動。8為(wei)聚焦鏡片,它與(yu)(yu)塑(su)(su)料(liao)骨(gu)架(jia)(jia)之間裝有橡(xiang)膠(jiao)密封圈(quan),使光線更(geng)(geng)加集中,射(she)程更(geng)(geng)遠。9為(wei)橡(xiang)膠(jiao)減震圈(quan),避免磁(ci)鐵直(zhi)接沖擊塑(su)(su)料(liao)骨(gu)架(jia)(jia)。將上(shang)(shang)面的(de)(de)材(cai)料(liao)作為(wei)一體,然(ran)后放(fang)入右面的(de)(de)塑(su)(su)料(liao)電(dian)(dian)筒(tong)外殼10內。電(dian)(dian)筒(tong)的(de)(de)滑動開關11與(yu)(yu)電(dian)(dian)路(lu)板(ban)的(de)(de)銅片相(xiang)對應(ying),再(zai)旋上(shang)(shang)電(dian)(dian)筒(tong)蓋12。這個電(dian)(dian)筒(tong)就(jiu)能使用(yong)了。
我(wo)們可(ke)以上下搖動(dong)這(zhe)個(ge)(ge)電(dian)(dian)(dian)(dian)筒(tong)(tong)。它就(jiu)能(neng)(neng)源源不(bu)斷(duan)地發光了。由于(yu)(yu)采(cai)用(yong)(yong)了超亮(liang)度(du)的(de)發白光二(er)極(ji)管(guan)并(bing)且有(you)(you)鏡片(pian)聚焦,亮(liang)度(du)和(he)射程大(da)于(yu)(yu)只使用(yong)(yong)聚焦電(dian)(dian)(dian)(dian)殊的(de)五號電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)手(shou)電(dian)(dian)(dian)(dian)筒(tong)(tong)。但(dan)這(zhe)個(ge)(ge)電(dian)(dian)(dian)(dian)筒(tong)(tong)亦有(you)(you)個(ge)(ge)顯(xian)著的(de)缺點,就(jiu)是(shi)(shi)要不(bu)停(ting)地搖才能(neng)(neng)不(bu)斷(duan)地發光。為了克服這(zhe)個(ge)(ge)缺點和(he)節約成本,我(wo)們沒有(you)(you)采(cai)用(yong)(yong)鋰(li)充(chong)(chong)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)增(zeng)加儲能(neng)(neng)。而(er)是(shi)(shi)在C1兩端并(bing)接兩只CR2032鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。實踐證(zheng)明(ming),由于(yu)(yu)這(zhe)個(ge)(ge)電(dian)(dian)(dian)(dian)筒(tong)(tong)的(de)耗電(dian)(dian)(dian)(dian)量約為30mA,新的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)可(ke)以用(yong)(yong)較長的(de)時(shi)(shi)間,電(dian)(dian)(dian)(dian)量不(bu)足時(shi)(shi)搖動(dong)電(dian)(dian)(dian)(dian)筒(tong)(tong)又能(neng)(neng)用(yong)(yong)上一段時(shi)(shi)問。反(fan)復(fu)多次后電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)完(wan)全失(shi)效后,取下電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)仍然可(ke)以繼續工(gong)作。如果你的(de)經濟條件許可(ke),將(jiang)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)換成鋰(li)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)那是(shi)(shi)最理想的(de)了。
