一、手搖手電筒原理是什么

手電筒中沒有電池(chi)，在晃動(dong)手電筒時，手電筒中的(de)永(yong)磁(ci)體在線圈中運(yun)動(dong)，運(yun)動(dong)是相(xiang)(xiang)對而(er)(er)言的(de)，相(xiang)(xiang)對于永(yong)磁(ci)體而(er)(er)言，線圈在做切割磁(ci)感線運(yun)動(dong)，所以會(hui)產生(sheng)感應電流，電流通過燈泡(pao)(pao)，燈泡(pao)(pao)就(jiu)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)筒(tong)(tong)是一種利用(yong)(yong)大功(gong)率的(de)三相(xiang)交(jiao)流發(fa)電(dian)(dian)(dian)(dian)機(ji)進(jin)行手(shou)(shou)搖發(fa)電(dian)(dian)(dian)(dian)的(de)設備，利用(yong)(yong)此(ci)原理(li)產生的(de)電(dian)(dian)(dian)(dian)能(neng)可(ke)(ke)以(yi)通過開關電(dian)(dian)(dian)(dian)源(yuan)來對手(shou)(shou)電(dian)(dian)(dian)(dian)筒(tong)(tong)的(de)電(dian)(dian)(dian)(dian)路(lu)系統進(jin)行內置充電(dian)(dian)(dian)(dian)。此(ci)種手(shou)(shou)電(dian)(dian)(dian)(dian)筒(tong)(tong)可(ke)(ke)以(yi)在(zai)較(jiao)為緊急(ji)的(de)情(qing)況下使用(yong)(yong)不(bu)僅(jin)具(ju)有(you)較(jiao)為便于攜帶的(de)作用(yong)(yong)還(huan)具(ju)有(you)結構簡(jian)單的(de)功(gong)能(neng)。在(zai)一些特殊的(de)情(qing)況下可(ke)(ke)以(yi)進(jin)行突(tu)然性的(de)照明使用(yong)(yong)，不(bu)僅(jin)如此(ci)手(shou)(shou)搖電(dian)(dian)(dian)(dian)筒(tong)(tong)的(de)發(fa)電(dian)(dian)(dian)(dian)量還(huan)可(ke)(ke)以(yi)在(zai)一定(ding)程度上用(yong)(yong)作手(shou)(shou)電(dian)(dian)(dian)(dian)筒(tong)(tong)的(de)備用(yong)(yong)電(dian)(dian)(dian)(dian)量。

該手搖動式(shi)自(zi)發(fa)電(dian)(dian)(dian)手電(dian)(dian)(dian)筒(tong)(tong)原(yuan)理圖(tu)(tu)如(ru)圖(tu)(tu)所(suo)示。其結構示意圖(tu)(tu)如(ru)圖(tu)(tu)2所(suo)示。在使(shi)(shi)用電(dian)(dian)(dian)筒(tong)(tong)時，搖動電(dian)(dian)(dian)筒(tong)(tong)使(shi)(shi)它的磁鐵7上(shang)下移動，通過線圈6即(ji)產生電(dian)(dian)(dian)能(neng)(neng)，再經圖(tu)(tu)2中(zhong)的D1-D4整(zheng)流(liu)，C1貯能(neng)(neng)向(xiang)電(dian)(dian)(dian)池CR2032充(chong)電(dian)(dian)(dian)通過開關控制(zhi)使(shi)(shi)發(fa)白光二極管發(fa)光而實現自(zi)發(fa)電(dian)(dian)(dian)的功能(neng)(neng)。

三、 手搖手電筒內部結構是怎么樣的

在(zai)圖中(zhong)，1為(wei)圓筒形的(de)塑(su)料(liao)(liao)骨架。2為(wei)發白光二極管3為(wei)電(dian)(dian)路(lu)板(ban)。4為(wei)用(yong)銅(tong)片(pian)制(zhi)作(zuo)的(de)開關(guan)。5為(wei)予留的(de)CR2032電(dian)(dian)池(chi)位置。6為(wei)空芯線(xian)圈，電(dian)(dian)感量約(yue)33mh，線(xian)徑(jing)約(yue)φ.2mm。7為(wei)強力(li)磁(ci)鐵，應使它能在(zai)圓筒內(nei)順利(li)的(de)上(shang)下(xia)移動。8為(wei)聚(ju)焦鏡片(pian)，它與塑(su)料(liao)(liao)骨架之(zhi)間裝有橡(xiang)膠密封圈，使光線(xian)更加集中(zhong)，射程(cheng)更遠。9為(wei)橡(xiang)膠減震圈，避免磁(ci)鐵直接(jie)沖擊塑(su)料(liao)(liao)骨架。將上(shang)面(mian)的(de)材料(liao)(liao)作(zuo)為(wei)一體，然后放入右面(mian)的(de)塑(su)料(liao)(liao)電(dian)(dian)筒外殼10內(nei)。電(dian)(dian)筒的(de)滑動開關(guan)11與電(dian)(dian)路(lu)板(ban)的(de)銅(tong)片(pian)相對應，再旋上(shang)電(dian)(dian)筒蓋(gai)12。這個電(dian)(dian)筒就能使用(yong)了。

我們(men)可以上下搖動這個電(dian)(dian)(dian)(dian)筒(tong)(tong)。它就能(neng)源源不斷地發(fa)光(guang)了。由于采用(yong)了超亮度的(de)發(fa)白光(guang)二極(ji)管(guan)并且有鏡片聚焦(jiao)，亮度和(he)射程大于只使用(yong)聚焦(jiao)電(dian)(dian)(dian)(dian)殊的(de)五號電(dian)(dian)(dian)(dian)池手電(dian)(dian)(dian)(dian)筒(tong)(tong)。但這個電(dian)(dian)(dian)(dian)筒(tong)(tong)亦有個顯著的(de)缺(que)(que)點(dian)(dian)，就是要不停(ting)地搖才能(neng)不斷地發(fa)光(guang)。為了克服這個缺(que)(que)點(dian)(dian)和(he)節約成(cheng)本(ben)，我們(men)沒有采用(yong)鋰(li)充電(dian)(dian)(dian)(dian)池增加儲能(neng)。而是在(zai)C1兩(liang)(liang)端并接兩(liang)(liang)只CR2032鋰(li)電(dian)(dian)(dian)(dian)池。實踐(jian)證明，由于這個電(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)池可以用(yong)較長的(de)時間，電(dian)(dian)(dian)(dian)量不足時搖動電(dian)(dian)(dian)(dian)筒(tong)(tong)又能(neng)用(yong)上一(yi)段時問。反復(fu)多次后(hou)電(dian)(dian)(dian)(dian)池完(wan)全(quan)失效(xiao)后(hou)，取下電(dian)(dian)(dian)(dian)池仍(reng)然可以繼續工作。如果你的(de)經濟條件許可，將(jiang)電(dian)(dian)(dian)(dian)池換(huan)成(cheng)鋰(li)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池那是最理想(xiang)的(de)了。
