  熒光燈分傳統型熒光燈和無極熒光燈,傳統型熒光燈即低壓汞燈,是利用低氣壓的汞蒸氣在放電過程中輻射紫外線,從而使熒光粉發出可見光的原理發光,因此它屬于低氣壓弧光放電光源。主要用放電產生的紫外輻射激發熒光粉而發光的防爆放電燈稱為防爆熒光燈。
  LED防爆熒光燈產品特點:
  1.高導熱性拉伸鋁外殼,陽極氧化處理,強度高,散熱好,耐腐蝕;
  2.硅橡膠密封,防護和耐老化性能優異,可適應各種惡劣環境;
  3.LED芯片,光效高、顯色性好;抗振動、耐沖擊;
  4.恒流式驅動,寬電壓輸入,智能保護電路;內部澆封,不產生電弧、火花及危險高溫;
  5.一體化應急功能設計,內置應急裝置,光感控制。
  LED防爆熒光燈安裝應符合下列規定:
  a、燈具的防爆標志、外殼防護等級和溫度組別與爆炸危險環境相適配。當設計無要求時,燈具種類和防爆結構的選型應符合下表的規定;
  b、燈具配套齊全,不用非防爆零件替代燈具配件(金屬護網、燈罩、接線盒等);
  c、燈具的安裝位置離開釋放源,且不在各種管道的泄壓口及排放口上下方安裝燈具;
  d、LED防爆熒光燈及開關安裝牢固可靠,燈具吊管及開關與接線盒螺紋嚙合扣數不少于5扣,螺紋加工光滑、完整、無銹蝕,并在螺紋上涂以電力復合酯或導電性防銹酯;
  e、開關安裝位置便于操作,安裝高度1.3m。
