一、手搖手電筒原理是什么

手電筒中沒有電池，在晃(huang)動手(shou)電筒(tong)時，手(shou)電筒(tong)中的(de)永磁體在線(xian)圈中運動，運動是相對(dui)而言的(de)，相對(dui)于永磁體而言，線(xian)圈在做切割(ge)磁感線(xian)運動，所(suo)以會(hui)產生感應(ying)電流，電流通過燈泡，燈泡就會(hui)發光。

二、手搖手電筒原理圖

手(shou)(shou)搖手(shou)(shou)電(dian)(dian)(dian)(dian)(dian)筒(tong)是一(yi)種利用(yong)大功率的(de)三相交流發(fa)電(dian)(dian)(dian)(dian)(dian)機進行(xing)手(shou)(shou)搖發(fa)電(dian)(dian)(dian)(dian)(dian)的(de)設備，利用(yong)此原理(li)產生的(de)電(dian)(dian)(dian)(dian)(dian)能可(ke)(ke)以(yi)(yi)通過開關電(dian)(dian)(dian)(dian)(dian)源來對手(shou)(shou)電(dian)(dian)(dian)(dian)(dian)筒(tong)的(de)電(dian)(dian)(dian)(dian)(dian)路系統進行(xing)內置充電(dian)(dian)(dian)(dian)(dian)。此種手(shou)(shou)電(dian)(dian)(dian)(dian)(dian)筒(tong)可(ke)(ke)以(yi)(yi)在較(jiao)為緊急的(de)情(qing)況下(xia)使(shi)用(yong)不僅(jin)具有(you)較(jiao)為便于攜帶的(de)作用(yong)還(huan)具有(you)結(jie)構簡單的(de)功能。在一(yi)些特殊的(de)情(qing)況下(xia)可(ke)(ke)以(yi)(yi)進行(xing)突然性的(de)照明(ming)使(shi)用(yong)，不僅(jin)如此手(shou)(shou)搖電(dian)(dian)(dian)(dian)(dian)筒(tong)的(de)發(fa)電(dian)(dian)(dian)(dian)(dian)量還(huan)可(ke)(ke)以(yi)(yi)在一(yi)定(ding)程度上用(yong)作手(shou)(shou)電(dian)(dian)(dian)(dian)(dian)筒(tong)的(de)備用(yong)電(dian)(dian)(dian)(dian)(dian)量。

該(gai)手搖動(dong)式(shi)自發(fa)電(dian)手電(dian)筒(tong)原理圖如圖所示(shi)。其結(jie)構示(shi)意圖如圖2所示(shi)。在使(shi)(shi)用電(dian)筒(tong)時，搖動(dong)電(dian)筒(tong)使(shi)(shi)它的(de)(de)磁鐵7上下移動(dong)，通過(guo)線圈6即產生電(dian)能，再經圖2中的(de)(de)D1-D4整流，C1貯能向電(dian)池CR2032充電(dian)通過(guo)開(kai)關控制使(shi)(shi)發(fa)白光二極管發(fa)光而實現自發(fa)電(dian)的(de)(de)功能。

三、 手搖手電筒內部結構是怎么樣的

在圖(tu)中(zhong)，1為(wei)圓筒(tong)形的(de)塑料(liao)(liao)骨架(jia)。2為(wei)發白(bai)光(guang)二極管3為(wei)電(dian)路板。4為(wei)用銅片(pian)(pian)制作的(de)開(kai)關。5為(wei)予留的(de)CR2032電(dian)池位置(zhi)。6為(wei)空芯線(xian)圈(quan)，電(dian)感量約(yue)33mh，線(xian)徑約(yue)φ.2mm。7為(wei)強力磁(ci)鐵，應使它能在圓筒(tong)內順利(li)的(de)上(shang)下移動(dong)。8為(wei)聚焦鏡片(pian)(pian)，它與塑料(liao)(liao)骨架(jia)之間裝(zhuang)有橡(xiang)膠密封(feng)圈(quan)，使光(guang)線(xian)更(geng)加集中(zhong)，射程更(geng)遠(yuan)。9為(wei)橡(xiang)膠減(jian)震圈(quan)，避免磁(ci)鐵直接沖擊塑料(liao)(liao)骨架(jia)。將(jiang)上(shang)面(mian)的(de)材料(liao)(liao)作為(wei)一(yi)體，然后放入右面(mian)的(de)塑料(liao)(liao)電(dian)筒(tong)外殼(ke)10內。電(dian)筒(tong)的(de)滑動(dong)開(kai)關11與電(dian)路板的(de)銅片(pian)(pian)相對應，再旋上(shang)電(dian)筒(tong)蓋12。這個電(dian)筒(tong)就能使用了。

我(wo)們(men)可(ke)(ke)以上下(xia)搖(yao)(yao)動這(zhe)(zhe)個(ge)(ge)電(dian)筒。它(ta)就能(neng)源(yuan)源(yuan)不斷地(di)(di)發(fa)光了。由于采用(yong)(yong)了超亮(liang)度的(de)(de)(de)發(fa)白光二極管并且有(you)(you)鏡片聚焦(jiao)，亮(liang)度和射(she)程大于只使用(yong)(yong)聚焦(jiao)電(dian)殊(shu)的(de)(de)(de)五(wu)號電(dian)池(chi)手(shou)電(dian)筒。但(dan)這(zhe)(zhe)個(ge)(ge)電(dian)筒亦有(you)(you)個(ge)(ge)顯著的(de)(de)(de)缺點(dian)，就是要不停(ting)地(di)(di)搖(yao)(yao)才(cai)能(neng)不斷地(di)(di)發(fa)光。為了克服這(zhe)(zhe)個(ge)(ge)缺點(dian)和節約成本(ben)，我(wo)們(men)沒有(you)(you)采用(yong)(yong)鋰(li)充(chong)電(dian)池(chi)增加儲(chu)能(neng)。而是在C1兩端并接兩只CR2032鋰(li)電(dian)池(chi)。實踐證明，由于這(zhe)(zhe)個(ge)(ge)電(dian)筒的(de)(de)(de)耗電(dian)量(liang)約為30mA，新的(de)(de)(de)電(dian)池(chi)可(ke)(ke)以用(yong)(yong)較長的(de)(de)(de)時間，電(dian)量(liang)不足時搖(yao)(yao)動電(dian)筒又(you)能(neng)用(yong)(yong)上一(yi)段時問。反復多(duo)次后電(dian)池(chi)完全失效(xiao)后，取下(xia)電(dian)池(chi)仍然可(ke)(ke)以繼續工作(zuo)。如果你的(de)(de)(de)經濟(ji)條件許可(ke)(ke)，將電(dian)池(chi)換成鋰(li)充(chong)電(dian)電(dian)池(chi)那是最理想的(de)(de)(de)了。
