a.探照燈的反射器由兩半組合而成，裝在各自的轉(zhuǎn)軸上，轉(zhuǎn)動(dòng)其角度，可使單一光束分成各與正前方水平夾角至少為5°的兩束光。單光束在離燈1800m時(shí)應(yīng)有1lx的照度（大氣透射比為0.85）,兩光束之間的暗區(qū)可在0°～10°范圍內(nèi)平滑變化。b.燈內(nèi)必須裝有兩個(gè)燈泡,如果一個(gè)發(fā)生故障,可直接切換另一個(gè)并自動(dòng)接通電源。c.燈體為水密型（能承受0.0245MPa的壓力）和氣密型（電氣設(shè)備應(yīng)能在危險(xiǎn)區(qū)域內(nèi)使用），并用軟管與裝有安全閥的通氣管相聯(lián)，將燈體內(nèi)的熱量排至安全區(qū)。d.燈的功率按船舶的蘇伊士運(yùn)河總噸位選用,不超過3萬總噸位的船舶為2000W,超過3萬總噸位的為3000W。燈的發(fā)光強(qiáng)度應(yīng)不低于3×106cd。e.燈體和支架由耐腐蝕材料制造，燈具能在水平和垂直兩個(gè)方向上轉(zhuǎn)動(dòng)。f.探照燈前玻璃為鋼化玻璃。g.反射鏡用優(yōu)質(zhì)鏡面玻璃或高純錳鋼拋光后制作。
