產品功能特(te)性：

鑄鋁合(he)金外客，表(biao)面噴塑(su)，防爆應急燈應急燈中正常照明燈和應急照明燈各自(zi)獨立,適合安裝條件許可的(de)場所;照明應急(ji)兩用(yong)燈(deng), LED防(fang)爆應急(ji)燈(deng)正常照明和應急(ji)照明共用(yong)一個燈(deng)體,光(guang)源獨立。防(fang)爆應急(ji)燈(deng)內裝免維護鎳(nie)鎘(ge)電池組，在正(zheng)常(chang)供電下自動(dong)充(chong)電，事故(gu)斷電或停(ting)電時應急燈自動(dong)點亮。　鋼管或電纜布線(xian)均可(ke)。LED防爆應急燈可(ke)根據(ju)用戶(hu)要求設置試驗按鈕和(he)指示燈具


產品工(gong)作原理：

防爆應急燈應急照明(ming)系(xi)統以自(zi)帶電源獨立控制型為主，正(zheng)常電源接自普(pu)通照明(ming)供電回路中，平時對應(ying)急燈(deng)蓄電池充(chong)電(dian)(dian)(dian)(dian)，當正(zheng)常(chang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)切斷時(shi)，備(bei)用(yong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)（蓄電(dian)(dian)(dian)(dian)池(chi)）自動(dong)供電(dian)(dian)(dian)(dian)。這種(zhong)(zhong)(zhong)形式的(de)(de)應急(ji)燈每個燈具(ju)內(nei)部都有(you)變(bian)壓、穩(wen)壓、充(chong)電(dian)(dian)(dian)(dian)、逆(ni)變(bian)、蓄電(dian)(dian)(dian)(dian)池(chi)等(deng)大量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)元器件，應急(ji)燈在(zai)使用(yong)、檢(jian)修(xiu)、故(gu)障(zhang)時(shi)電(dian)(dian)(dian)(dian)池(chi)均(jun)需充(chong)放電(dian)(dian)(dian)(dian)。 另一種(zhong)(zhong)(zhong)是集(ji)中(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)集(ji)中(zhong)(zhong)(zhong)控制型，應急(ji)燈具(ju)內(nei)無(wu)獨立電(dian)(dian)(dian)(dian)源(yuan)(yuan)，正(zheng)常(chang)照(zhao)(zhao)(zhao)明電(dian)(dian)(dian)(dian)源(yuan)(yuan)故(gu)障(zhang)時(shi)，由集(ji)中(zhong)(zhong)(zhong)供電(dian)(dian)(dian)(dian)系統(tong)供電(dian)(dian)(dian)(dian)。在(zai)這種(zhong)(zhong)(zhong)形式的(de)(de)應急(ji)照(zhao)(zhao)(zhao)明系統(tong)中(zhong)(zhong)(zhong)，所(suo)有(you)燈具(ju)內(nei)部復雜的(de)(de)電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)路被省掉了，應急(ji)照(zhao)(zhao)(zhao)明燈具(ju)與普通的(de)(de)燈具(ju)無(wu)異，集(ji)中(zhong)(zhong)(zhong)供電(dian)(dian)(dian)(dian)系統(tong)設(she)置在(zai)的房間內。


防爆燈具的(de)分類：

◆防(fang)爆燈具(ju)的防(fang)爆類別(bie)(bie)、級別(bie)(bie)與(yu)溫度組別(bie)(bie)見國(guo)家標準規定。

◆按防爆型(xing)(xing)式分(fen)為隔(ge)爆型(xing)(xing)、增安(an)型(xing)(xing)、正壓(ya)型(xing)(xing)、無火花(hua)型(xing)(xing)和粉塵防爆型(xing)(xing)共5種主要類型(xing)(xing)

◆按防觸電保護(hu)型式可分為(wei)Ⅰ、Ⅱ、Ⅲ類(lei)。

◆按(an)外(wai)殼的防(fang)護(hu)等級分類：為了防(fang)護(hu)塵埃(ai)、固體異物和水進(jin)入燈(deng)腔內(nei)，觸(chu)及或積集在帶電部件上產生跳火、短路或破壞電氣絕(jue)緣等危(wei)險，有多種外(wai)殼防(fang)護(hu)方式起到保(bao)護(hu)電氣絕(jue)緣的作用(yong)。

◆按燈(deng)具設計的支撐(cheng)面材料(liao)分類：室內(nei)防爆燈(deng)具可能安裝在許多屬于普通(tong)可燃材料(liao)表(biao)面，如木質(zhi)的墻和天花板，它(ta)們(men)不(bu)允許防(fang)爆燈(deng)具安裝表面(mian)的溫度超過安全數(shu)值。

◆按安(an)裝使用形式(shi)可(ke)分(fen)為固(gu)定(ding)式(shi)、可(ke)移式(shi)、攜帶式(shi)。
