G7785B-60W免維護防爆LED節能照明燈燈(deng)(deng)(deng)是防(fang)(fang)爆(bao)燈(deng)(deng)(deng)的(de)(de)(de)一(yi)種，其(qi)原(yuan)理同防(fang)(fang)爆(bao)燈(deng)(deng)(deng)相同，只(zhi)不過(guo)光源是LED光源，是指為(wei)了(le)防(fang)(fang)止點(dian)燃(ran)周圍性(xing)混合物(wu)如性(xing)氣(qi)體環境(jing)、性(xing)粉塵環境(jing)、氣(qi)體等而采取的(de)(de)(de)各種特定措(cuo)施(shi)的(de)(de)(de)燈(deng)(deng)(deng)具(ju)。LED防(fang)(fang)爆(bao)燈(deng)(deng)(deng)是節能(neng)的(de)(de)(de)防(fang)(fang)爆(bao)燈(deng)(deng)(deng)具(ju)，廣泛用(yong)(yong)于油田-電(dian)廠-化工廠-石油-。LED防(fang)(fang)爆(bao)燈(deng)(deng)(deng)具(ju)的(de)(de)(de)其(qi)中(zhong)一(yi)個非常重要的(de)(de)(de)防(fang)(fang)爆(bao)原(yuan)理就是限制與性(xing)氣(qi)體、性(xing)粉塵接觸(chu)的(de)(de)(de)外(wai)殼(ke)表(biao)(biao)面(mian)、零部件(jian)表(biao)(biao)面(mian)或(huo)電(dian)子(zi)元器件(jian)表(biao)(biao)面(mian)的(de)(de)(de)溫(wen)度以及限制電(dian)氣(qi)接觸(chu)表(biao)(biao)面(mian)溫(wen)度低于其(qi)小點(dian)燃(ran)溫(wen)度或(huo)引燃(ran)溫(wen)度。在戶外(wai)使用(yong)(yong)的(de)(de)(de)led防(fang)(fang)爆(bao)燈(deng)(deng)(deng)，需(xu)要使用(yong)(yong)防(fang)(fang)水(shui)驅動。在加油站(zhan)使用(yong)(yong)的(de)(de)(de)led防(fang)(fang)爆(bao)燈(deng)(deng)(deng)需(xu)要防(fang)(fang)震(zhen)！由于LED屬于固態冷光源，具(ju)有電(dian)光轉(zhuan)換效率(lv)高、發(fa)熱(re)量(liang)小、耗電(dian)量(liang)小、工作電(dian)壓(ya)屬*低電(dian)壓(ya)、使用(yong)(yong)壽命長等優點(dian)，低能(neng)耗；因此大功率(lv)白光LED是防(fang)(fang)爆(bao)燈(deng)(deng)(deng)具(ju)。
特別是可攜式防爆(bao)燈(deng)(deng)(deng)(deng)具(ju)的(de)一(yi)種(zhong)非常理想(xiang)的(de)電(dian)(dian)(dian)(dian)(dian)光源(yuan)。LED防爆(bao)燈(deng)(deng)(deng)(deng)，區路密(mi)封技術；更(geng)符合*防爆(bao)新技術。屬于(yu)一(yi)種(zhong)特種(zhong)行業中用電(dian)(dian)(dian)(dian)(dian)氣設(she)備，主(zhu)要解決(jue)照明問(wen)題，它包(bao)括(kuo)燈(deng)(deng)(deng)(deng)殼(ke)、設(she)置在燈(deng)(deng)(deng)(deng)殼(ke)前端的(de)燈(deng)(deng)(deng)(deng)罩、設(she)置于(yu)燈(deng)(deng)(deng)(deng)殼(ke)內部的(de)發(fa)光體(ti)及電(dian)(dian)(dian)(dian)(dian)池、設(she)置于(yu)燈(deng)(deng)(deng)(deng)殼(ke)表面的(de)開(kai)關(guan)，其特征在于(yu)：發(fa)光體(ti)為大功(gong)率LED模(mo)(mo)(mo)組(zu)，在發(fa)光體(ti)與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)池之(zhi)間設(she)有寬電(dian)(dian)(dian)(dian)(dian)壓輸入(ru)驅(qu)(qu)動(dong)電(dian)(dian)(dian)(dian)(dian)路；寬電(dian)(dian)(dian)(dian)(dian)壓輸入(ru)驅(qu)(qu)動(dong)電(dian)(dian)(dian)(dian)(dian)路包(bao)括(kuo)恒流芯(xin)片(pian)(pian)，恒流芯(xin)片(pian)(pian)與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)池組(zu)成電(dian)(dian)(dian)(dian)(dian)源(yuan)模(mo)(mo)(mo)組(zu)，LED模(mo)(mo)(mo)組(zu)連接在恒流芯(xin)片(pian)(pian)上，電(dian)(dian)(dian)(dian)(dian)源(yuan)模(mo)(mo)(mo)組(zu)與(yu)(yu)LED模(mo)(mo)(mo)組(zu)膠封在一(yi)起；燈(deng)(deng)(deng)(deng)罩與(yu)(yu)燈(deng)(deng)(deng)(deng)殼(ke)之(zhi)間為超音波焊接。
G7785B-60W免維護防爆LED節能照明燈它利用LED低發熱量的(de)特點(dian)，實現本質*級防爆(bao)，而且LED光(guang)源壽(shou)命長；電池在充(chong)滿電和放電末期LED都(dou)保(bao)持恒定亮度；在燈殼上(shang)設置散(san)熱裝置，可以實現LED模組的(de)有效散(san)熱。
