應急管理綜合行政防爆LED閃光燈裝備的電路由四部分組成：振蕩升壓部分、整流充電部分、電壓指示部分和脈沖觸發閃光部分。

當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)接(jie)通后，利用晶體(ti)管(guan)(guan)V1的(de)(de)(de)開關特性(xing)，形成(cheng)一個間歇振(zhen)蕩，使T1的(de)(de)(de)初級獲得(de)一個交變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，經T1升壓(ya)，使其次(ci)級獲得(de)大于300V的(de)(de)(de)交變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。交變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)經二極(ji)管(guan)(guan)D1半波(bo)整流(liu)后變(bian)成(cheng)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，對(dui)主電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C2和觸發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C3充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)儲能(neng)。當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)充至額定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)70%左(zuo)右時(shi)，指示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中的(de)(de)(de)氖(nai)燈（Ne）起輝，指示(shi)閃(shan)光(guang)(guang)燈處于正常閃(shan)光(guang)(guang)等(deng)待狀態。當(dang)按下(xia)按鈕AN，觸發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路（由(you)R3、C3、T2和Xe組成(cheng)）產(chan)生脈沖(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，在T2的(de)(de)(de)次(ci)級感應出瞬間高壓(ya)（約10kV）脈沖(chong)，通過(guo)Xe閃(shan)光(guang)(guang)管(guan)(guan)的(de)(de)(de)觸發(fa)極(ji)使Xe閃(shan)光(guang)(guang)管(guan)(guan)內(nei)氮氣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離并導通，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C2上儲存的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)瞬間通過(guo)閃(shan)光(guang)(guang)燈管(guan)(guan)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)轉化為光(guang)(guang)能(neng)，完成(cheng)一次(ci)閃(shan)光(guang)(guang)。

應急管理綜合行政防爆LED閃光燈裝備大致的可以分為三類，根據其類型不同，其功能和性能也是不同。

內(nei)置閃(shan)光(guang)燈(deng)(deng) ，使用內(nei)置閃(shan)光(guang)燈(deng)(deng)會造成相(xiang)機電量的大量消耗，而且內(nei)置閃(shan)光(guang)燈(deng)(deng)不支持(chi)閃(shan)光(guang)燈(deng)(deng)的各種高級功能。

外置閃(shan)光燈， 外置閃(shan)光燈一般位于(yu)相(xiang)機(ji)機(ji)身頂部(bu)，一些外置閃(shan)光燈還提(ti)供各種高級的功(gong)能(neng)。

手柄(bing)(bing)式閃(shan)光燈(deng)，手柄(bing)(bing)式閃(shan)光燈(deng)常用于照(zhao)相館、影樓、婚紗攝影工(gong)作室等(deng)場(chang)所(suo)。
