應急燈原理是什么? 消防(fang)應急照明燈布燈位置(zhi)

應急燈的作用

消防應急燈作為在(zai)火(huo)災現場(chang)及(ji)不可抗拒災難事故發生(sheng)時(shi)，為被困在(zai)事故現場(chang)的人員尋找（發現）緊急逃生(sheng)安全出口(kou)通道時(shi)提供(gong)應急照明(ming)和方向指示(shi)的必備燈具(ju)。

當(dang)發(fa)生突發(fa)性的(de)停(ting)電、火災事故的(de)發(fa)生或地(di)震(zhen)等不可抗拒的(de)災難事故發(fa)生時，用于事故現場(chang)人(ren)員(yuan)的(de)緊急疏散(san)，迅速逃(tao)離現場(chang)，對被困現場(chang)人(ren)員(yuan)的(de)營救，提供指示照明；并(bing)且適用于一般家庭的(de)使用。

應急燈原理

國內使用(yong)(yong)的應(ying)急照(zhao)(zhao)明系統以自帶電(dian)(dian)(dian)(dian)(dian)(dian)源獨立控制型為主，正常電(dian)(dian)(dian)(dian)(dian)(dian)源接自普通照(zhao)(zhao)明供電(dian)(dian)(dian)(dian)(dian)(dian)回路中(zhong)，平時(shi)對應(ying)急燈蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)，當(dang)正常電(dian)(dian)(dian)(dian)(dian)(dian)源切斷時(shi)，備(bei)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)源（蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)）自動供電(dian)(dian)(dian)(dian)(dian)(dian)。這種(zhong)形式的應(ying)急燈每個燈具內部都有(you)變壓、穩壓、充電(dian)(dian)(dian)(dian)(dian)(dian)、逆變、蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)等大量的電(dian)(dian)(dian)(dian)(dian)(dian)子元器(qi)件，應(ying)急燈在使用(yong)(yong)、檢修、故(gu)障時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)均需(xu)充放電(dian)(dian)(dian)(dian)(dian)(dian)。

另一種是集中(zhong)電(dian)(dian)(dian)源集中(zhong)控制型，應急燈(deng)(deng)具(ju)(ju)內無(wu)(wu)獨立(li)電(dian)(dian)(dian)源，正常照(zhao)明(ming)電(dian)(dian)(dian)源故障時，由集中(zhong)供(gong)電(dian)(dian)(dian)系(xi)統(tong)(tong)供(gong)電(dian)(dian)(dian)。在這(zhe)種形式的(de)(de)(de)(de)應急照(zhao)明(ming)系(xi)統(tong)(tong)中(zhong)，所有(you)燈(deng)(deng)具(ju)(ju)內部(bu)復雜(za)的(de)(de)(de)(de)電(dian)(dian)(dian)子電(dian)(dian)(dian)路被省掉了，應急照(zhao)明(ming)燈(deng)(deng)具(ju)(ju)與普通的(de)(de)(de)(de)燈(deng)(deng)具(ju)(ju)無(wu)(wu)異，集中(zhong)供(gong)電(dian)(dian)(dian)系(xi)統(tong)(tong)設置(zhi)在專用(yong)的(de)(de)(de)(de)房(fang)間內。

應急燈安裝高度

常(chang)見(jian)的(de)(de)(de)(de)消防應(ying)急(ji)照明燈，一(yi)般安裝在(zai)2.2米或(huo)(huo)以(yi)(yi)上的(de)(de)(de)(de)高(gao)度(du)，多以(yi)(yi)懸(xuan)掛(gua)式或(huo)(huo)壁掛(gua)式掛(gua)置于安全(quan)出口（消防安全(quan)通道）的(de)(de)(de)(de)上方或(huo)(huo)門框(kuang)的(de)(de)(de)(de)上方。在(zai)火災發(fa)(fa)生或(huo)(huo)停電之時，自動點(dian)亮，作(zuo)(zuo)為應(ying)急(ji)照明燈具，提供應(ying)急(ji)照明條(tiao)件。在(zai)火災發(fa)(fa)生的(de)(de)(de)(de)初期發(fa)(fa)揮的(de)(de)(de)(de)作(zuo)(zuo)用大一(yi)些(xie)。
