防爆LED閃(shan)光(guang)燈電(dian)(dian)(dian)(dian)(dian)路由四部(bu)(bu)(bu)分組成(cheng):振(zhen)蕩升壓(ya)部(bu)(bu)(bu)分、整(zheng)流(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)部(bu)(bu)(bu)分、電(dian)(dian)(dian)(dian)(dian)壓(ya)指示部(bu)(bu)(bu)分和脈沖觸(chu)發閃(shan)光(guang)部(bu)(bu)(bu)分。當電(dian)(dian)(dian)(dian)(dian)源(yuan)接通(tong)后,利用晶體管(guan)V1的(de)開關特性,形成(cheng)一(yi)個間歇振(zhen)蕩,使T1的(de)初級(ji)獲得一(yi)個交變(bian)電(dian)(dian)(dian)(dian)(dian)壓(ya),經T1升壓(ya),使其次級(ji)獲得大于(yu)300V的(de)交變(bian)電(dian)(dian)(dian)(dian)(dian)壓(ya)。交變(bian)電(dian)(dian)(dian)(dian)(dian)壓(ya)經二極(ji)管(guan)D1半波整(zheng)流(liu)(liu)后變(bian)成(cheng)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)壓(ya),對主電(dian)(dian)(dian)(dian)(dian)容C2和觸(chu)發電(dian)(dian)(dian)(dian)(dian)容C3充電(dian)(dian)(dian)(dian)(dian)儲能(neng)。當電(dian)(dian)(dian)(dian)(dian)壓(ya)充至額定電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)70%左右(you)時(shi),指示電(dian)(dian)(dian)(dian)(dian)路中的(de)氖(nai)燈(Ne)起輝(hui),指示閃(shan)光(guang)燈處于(yu)正常閃(shan)光(guang)等待狀(zhuang)態。當按下按鈕(niu)AN,觸(chu)發電(dian)(dian)(dian)(dian)(dian)路(由R3、C3、T2和Xe組成(cheng))產生脈沖電(dian)(dian)(dian)(dian)(dian)壓(ya),在(zai)T2的(de)次級(ji)感應出瞬間高壓(ya)(約10kV)脈沖,通(tong)過Xe閃(shan)光(guang)管(guan)的(de)觸(chu)發極(ji)使Xe閃(shan)光(guang)管(guan)內氮氣電(dian)(dian)(dian)(dian)(dian)離并導通(tong),電(dian)(dian)(dian)(dian)(dian)容C2上(shang)儲存的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)瞬間通(tong)過閃(shan)光(guang)燈管(guan)放(fang)電(dian)(dian)(dian)(dian)(dian)轉化(hua)為光(guang)能(neng),完成(cheng)一(yi)次閃(shan)光(guang)。
