E increased safety without arcing under normal operating conditions, the spark of electrical equipment to take some additional measures to improve its safety explosion-proof lighting group, to prevent dangerous temperature, the possibility of arcing and sparks explosion of its internal and external parts that may arise type of explosion-proof lighting, further protective measures on the structure and improve the reliability and safety of the device. All circuits are inside the device under standard conditions (including normal operation and specified fault conditions) explosion-proof lighting fittings, any spark or produce any effects are not the point of intrinsically safe circuits provided proof of natural gas environment. (1) The structure and principle: You can say that the efficiency of the high-pressure mercury lamp and color improvement by emitting tube out of a high-pressure discharge lamp enclosed gas types are as follows: Se-Na system Na-Tl-In system Dy- Tl-In relation to the light of the Sn-based system is concerned, can be divided into transparent type, diffusion (phosphor coating inside the outer tube) and a reflective type.
