A proof lighting allows the operating position where the explosion led lights, some proof lighting installation is only allowed in a certain position or a certain angle range, which is set to change because of work pulling, explosion-proof lighting surface heat distribution and maximum surface temperature proof led light will change, the reason for the explosion-proof lighting work position limits, the main reason is that the maximum surface temperature in order to control, to prevent its explosion-proof lighting itself mark over temperature class, dangerous temperatures. In addition, changes in work location will have an impact on the life and performance of some light, have an impact on lighting insulation, electrical components, insulation of different lines, life, etc. will. Therefore, the installation location restrictions of explosion-proof lighting must be clearly defined. B To reduce the maximum surface temperature of explosion-proof lighting, reducing the product temperature grouping levels, design specifications of the light source is made of special explosion-proof lighting source shall indicate the name, type, shape and size of the bulb and plant. If not specified, the user switch to other same power of the bulb, the maximum surface temperature of explosion-proof lighting is likely to exceed the use of a bad environment in the ignition temperature of the explosive gas mixture explosion led lamp type, constitute an explosion hazard. C under the most unfavorable conditions of normal operation, the power cable or wire insulation material in the fixture by the maximum temperature exceeds 80t should be flagged so that matching the corresponding cables and wires. The introduction of cables or wires have special requirements, must be marked specifications, models and application temperature. D lamps with batteries stating the type of battery, nominal voltage and nominal capacity, so as to avoid damage and danger. E converging to have similar properties and explosion-proof lighting should be marked according to the shortest distance from the object to prevent the illuminated objects scorched and burned. F ballast coil rated maximum operating temperature tω (C), the capacitor's rated maximum operating temperature tc (C), multifunction LED searchlight to meet the railway, electricity, public security, fire, military, oil, petrochemical, metallurgy, and other enterprises over require high brightness lighting, research development and production of WXT2830 multifunction LED searchlight explosion led lamp manufacturers, for public security patrol, fire command, border patrol, electrical repairs, enterprises and institutions guards, at night incidents search, flood and so on. Light efficiency energy: source selection of imported special high brightness solid state maintenance-free LED light source, low energy consumption, high luminous efficiency, soft light, condenser, and do not cause workers eye visual fatigue, improve work efficiency, the average life of up to 10 million hours. Long lighting time, up to 5 hours of continuous illumination. Proof led light, where to sell _ leading professional manufacturers Koretoyo explosion proof led light _ peace by Zhejiang Koretoyo explosion-proof electrical Co., Ltd. Tianjin offices.
