礦用本安型防爆閃光燈外形小巧，使用安全，攜帶方便，性能穩定。
電(dian)(dian)(dian)(dian)(dian)(dian)路由(you)四部分(fen)組(zu)成(cheng)(cheng)(cheng):振蕩升壓(ya)(ya)(ya)部分(fen)、整流(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)部分(fen)、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)指示部分(fen)和(he)脈沖觸(chu)發閃(shan)光(guang)部分(fen)。 當電(dian)(dian)(dian)(dian)(dian)(dian)源接通后，利用晶體管V1的(de)開關特性，形(xing)成(cheng)(cheng)(cheng)一(yi)個(ge)間(jian)歇振蕩，使(shi)T1的(de)初級(ji)獲得一(yi)個(ge)交(jiao)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，經(jing)T1升壓(ya)(ya)(ya)，使(shi)其次級(ji)獲得大(da)于300V的(de)交(jiao)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)。交(jiao)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)經(jing)二極(ji)管D1半波整流(liu)后變(bian)(bian)成(cheng)(cheng)(cheng)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，對主電(dian)(dian)(dian)(dian)(dian)(dian)容C2和(he)觸(chu)發電(dian)(dian)(dian)(dian)(dian)(dian)容C3充電(dian)(dian)(dian)(dian)(dian)(dian)儲能。當電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)充至(zhi)額定電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)70%左右時，指示電(dian)(dian)(dian)(dian)(dian)(dian)路中的(de)氖燈(deng)(Ne)起輝，指示閃(shan)光(guang)燈(deng)處于正(zheng)常閃(shan)光(guang)等(deng)待狀(zhuang)態(tai)。當按下按鈕AN，觸(chu)發電(dian)(dian)(dian)(dian)(dian)(dian)路(由(you)R3、C3、T2和(he)Xe組(zu)成(cheng)(cheng)(cheng))產生脈沖電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，在(zai)T2的(de)次級(ji)感(gan)應出瞬間(jian)高壓(ya)(ya)(ya)(約(yue)10kV)脈沖，通過Xe閃(shan)光(guang)管的(de)觸(chu)發極(ji)使(shi)Xe閃(shan)光(guang)管內氮(dan)氣電(dian)(dian)(dian)(dian)(dian)(dian)離并導(dao)通，電(dian)(dian)(dian)(dian)(dian)(dian)容C2上儲存的(de)電(dian)(dian)(dian)(dian)(dian)(dian)能瞬間(jian)通過閃(shan)光(guang)燈(deng)管放電(dian)(dian)(dian)(dian)(dian)(dian)轉化為光(guang)能，完成(cheng)(cheng)(cheng)一(yi)次閃(shan)光(guang)。
礦用本安型防爆閃光燈大致可(ke)以分為三類，根據其(qi)類型不同(tong)，其(qi)功能和性能也不同(tong)。
內置閃光(guang)燈(deng)(deng) ，使用內置閃光(guang)燈(deng)(deng)會造成相機電(dian)量的(de)大量消耗，而且內置閃光(guang)燈(deng)(deng)不支持閃光(guang)燈(deng)(deng)的(de)各(ge)種高(gao)級功能。
外(wai)(wai)置閃(shan)光燈， 外(wai)(wai)置閃(shan)光燈一般位于相機機身頂部，一些外(wai)(wai)置閃(shan)光燈還提(ti)供各(ge)種高級的功能。
手柄式閃光(guang)燈(deng)，手柄式閃光(guang)燈(deng)常用于照(zhao)相館、影樓、婚紗攝影工作室等(deng)場所。
