Proof lamp refers to the presence of flammable gases and dust-proof metal halide Philips dangerous places, to prevent arcing, sparks and heat generated inside the lamp may ignite combustible environment surrounding gas and dust, so as to achieve the required proof lamps. Also known as explosion-proof lighting, explosion-proof lighting. Flammable gas mixtures of different environments and proof in the form of explosion proof lights grades have different requirements. With specific reference to GB3836, IEC60079. (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. 150w metal halide lamp explosion, explosion-proof metal halide Hengshui, Koretoyo by Zhejiang Koretoyo explosion-proof electrical Co., Ltd.
