一、手搖手電筒原理是什么

手電筒中沒有電(dian)池(chi)，在(zai)(zai)晃動(dong)手電(dian)筒時，手電(dian)筒中的永磁(ci)體在(zai)(zai)線圈(quan)中運動(dong)，運動(dong)是(shi)相對而(er)言(yan)的，相對于永磁(ci)體而(er)言(yan)，線圈(quan)在(zai)(zai)做切(qie)割磁(ci)感(gan)(gan)線運動(dong)，所以會(hui)(hui)產生感(gan)(gan)應(ying)電(dian)流(liu)，電(dian)流(liu)通過燈泡(pao)，燈泡(pao)就會(hui)(hui)發(fa)光。

二、手搖手電筒原理圖

手(shou)搖手(shou)電(dian)(dian)(dian)筒(tong)是一(yi)種利(li)用(yong)大功率的(de)(de)(de)(de)(de)三(san)相交流發電(dian)(dian)(dian)機(ji)進(jin)(jin)行(xing)手(shou)搖發電(dian)(dian)(dian)的(de)(de)(de)(de)(de)設備，利(li)用(yong)此(ci)原(yuan)理(li)產(chan)生(sheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)能可(ke)以(yi)(yi)通過(guo)開(kai)關電(dian)(dian)(dian)源來(lai)對手(shou)電(dian)(dian)(dian)筒(tong)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)路系統進(jin)(jin)行(xing)內置(zhi)充電(dian)(dian)(dian)。此(ci)種手(shou)電(dian)(dian)(dian)筒(tong)可(ke)以(yi)(yi)在較(jiao)為緊急的(de)(de)(de)(de)(de)情況下(xia)使(shi)用(yong)不僅具(ju)有較(jiao)為便于攜帶的(de)(de)(de)(de)(de)作(zuo)用(yong)還(huan)具(ju)有結構簡單的(de)(de)(de)(de)(de)功能。在一(yi)些(xie)特殊(shu)的(de)(de)(de)(de)(de)情況下(xia)可(ke)以(yi)(yi)進(jin)(jin)行(xing)突(tu)然性(xing)的(de)(de)(de)(de)(de)照明使(shi)用(yong)，不僅如此(ci)手(shou)搖電(dian)(dian)(dian)筒(tong)的(de)(de)(de)(de)(de)發電(dian)(dian)(dian)量還(huan)可(ke)以(yi)(yi)在一(yi)定(ding)程度上(shang)用(yong)作(zuo)手(shou)電(dian)(dian)(dian)筒(tong)的(de)(de)(de)(de)(de)備用(yong)電(dian)(dian)(dian)量。

該手(shou)(shou)搖動(dong)式自發電(dian)(dian)手(shou)(shou)電(dian)(dian)筒(tong)原理圖如(ru)圖所(suo)示(shi)。其結構示(shi)意圖如(ru)圖2所(suo)示(shi)。在使(shi)用電(dian)(dian)筒(tong)時，搖動(dong)電(dian)(dian)筒(tong)使(shi)它(ta)的(de)磁鐵7上下移(yi)動(dong)，通過(guo)線圈6即產生(sheng)電(dian)(dian)能，再經圖2中(zhong)的(de)D1-D4整(zheng)流，C1貯能向電(dian)(dian)池CR2032充(chong)電(dian)(dian)通過(guo)開關控制(zhi)使(shi)發白(bai)光(guang)(guang)二極管發光(guang)(guang)而實現(xian)自發電(dian)(dian)的(de)功能。

三、 手搖手電筒內部結構是怎么樣的

在圖中(zhong)，1為(wei)(wei)(wei)(wei)圓筒(tong)(tong)(tong)(tong)(tong)形的(de)(de)塑(su)(su)料骨架。2為(wei)(wei)(wei)(wei)發白光二極管3為(wei)(wei)(wei)(wei)電(dian)路(lu)板。4為(wei)(wei)(wei)(wei)用銅片制作的(de)(de)開關。5為(wei)(wei)(wei)(wei)予留的(de)(de)CR2032電(dian)池位置(zhi)。6為(wei)(wei)(wei)(wei)空芯線圈，電(dian)感量約33mh，線徑約φ.2mm。7為(wei)(wei)(wei)(wei)強力(li)磁(ci)鐵，應使(shi)它(ta)能(neng)在圓筒(tong)(tong)(tong)(tong)(tong)內(nei)順利的(de)(de)上下移動。8為(wei)(wei)(wei)(wei)聚(ju)焦鏡片，它(ta)與塑(su)(su)料骨架之間裝有橡(xiang)膠密封圈，使(shi)光線更(geng)加集中(zhong)，射程更(geng)遠。9為(wei)(wei)(wei)(wei)橡(xiang)膠減(jian)震(zhen)圈，避免(mian)磁(ci)鐵直接沖擊(ji)塑(su)(su)料骨架。將上面(mian)的(de)(de)材料作為(wei)(wei)(wei)(wei)一體(ti)，然后放入右面(mian)的(de)(de)塑(su)(su)料電(dian)筒(tong)(tong)(tong)(tong)(tong)外殼10內(nei)。電(dian)筒(tong)(tong)(tong)(tong)(tong)的(de)(de)滑動開關11與電(dian)路(lu)板的(de)(de)銅片相對(dui)應，再(zai)旋上電(dian)筒(tong)(tong)(tong)(tong)(tong)蓋12。這(zhe)個(ge)電(dian)筒(tong)(tong)(tong)(tong)(tong)就(jiu)能(neng)使(shi)用了。

我們可(ke)(ke)以上(shang)下搖(yao)動(dong)這個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)筒(tong)(tong)。它就(jiu)能(neng)源(yuan)源(yuan)不斷地發(fa)光(guang)了。由于(yu)采用(yong)(yong)(yong)了超亮度(du)的(de)(de)(de)發(fa)白(bai)光(guang)二極管并且有(you)鏡片聚焦(jiao)，亮度(du)和射程大于(yu)只(zhi)使用(yong)(yong)(yong)聚焦(jiao)電(dian)(dian)(dian)(dian)(dian)殊的(de)(de)(de)五(wu)號電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)手電(dian)(dian)(dian)(dian)(dian)筒(tong)(tong)。但這個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)筒(tong)(tong)亦有(you)個(ge)(ge)顯(xian)著的(de)(de)(de)缺(que)點，就(jiu)是(shi)(shi)(shi)要不停地搖(yao)才能(neng)不斷地發(fa)光(guang)。為(wei)了克服這個(ge)(ge)缺(que)點和節約成(cheng)本，我們沒有(you)采用(yong)(yong)(yong)鋰充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)增(zeng)加儲能(neng)。而是(shi)(shi)(shi)在C1兩端并接兩只(zhi)CR2032鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。實踐證明，由于(yu)這個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)筒(tong)(tong)的(de)(de)(de)耗電(dian)(dian)(dian)(dian)(dian)量約為(wei)30mA，新的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)可(ke)(ke)以用(yong)(yong)(yong)較(jiao)長(chang)的(de)(de)(de)時間，電(dian)(dian)(dian)(dian)(dian)量不足時搖(yao)動(dong)電(dian)(dian)(dian)(dian)(dian)筒(tong)(tong)又能(neng)用(yong)(yong)(yong)上(shang)一段(duan)時問。反(fan)復多(duo)次后電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)完(wan)全失(shi)效后，取下電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)仍然可(ke)(ke)以繼續工作。如(ru)果你的(de)(de)(de)經濟(ji)條(tiao)件許可(ke)(ke)，將電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)換(huan)成(cheng)鋰充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)那是(shi)(shi)(shi)最(zui)理想(xiang)的(de)(de)(de)了。
