When using aluminum and other light alloys as flameproof enclosure Explosion-proof lights, due to the lower strength aluminum alloy, therefore, always open (such as replacement of light required to open) flameproof enclosure when using screws proof lights, not directly on the aluminum alloy shell tapping proof lights bcd200, should by rebar embedded and external locking sleeve proof lights, to increase the strength of the screw holes and screw to prevent tooth decay and failure; not require the user to replace the light source when you open or repair has been installed and the factory bolts can be fastened directly tapping screw holes on the case, but you can not use fine thread, try to use coarse thread, and there is enough to satisfy the number of meshing buckle fastening requirements . Similar construction to the mercury lamp, and then the light emitting tube, in addition to mercury, argon gas, but also other metal halide compound is enclosed as a luminescent substance, the use of these elements is sealed to emit light.
