Advanced production equipment, strong technical force, strict testing means, a scientific management system, creating a high quality lighting products. Through the ISO9001: 2000 quality system certification. Allows the company to be promoted in all aspects of the production, management, quality, etc., competitiveness increasingly strengthened. Explosion-proof electrical products are in strict accordance with the GB3836-2000 "explosive gas environment with electrical equipment" and other relevant standards, is committed to China's coal industry, petroleum, petrochemical, power, metallurgy, railway, ships, stadiums, military, aerospace , public security and fire and large chemical companies and other target markets and customer segments, to provide "simple, reliable, energy saving and environmental protection" products and "value for money, value for money" service, providing specialized lighting solutions and package system lighting service. LED (Light Emitting Diode) is a solid state semiconductor devices, which can be converted directly into electricity to light. LED's heart is the end of a semiconductor chip, the chip attached to a bracket on the LED, one end is negative, and the other end connected to the positive supply. A proof lighting allows the working position, some proof lighting installation only allowed within 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 will change, the Therefore, the operating position of the explosion-proof lighting explosion limit led lamp manufacturers, the main reason is to control for the maximum surface temperature, do not let it exceeds temperature class explosion proof lighting led lights specification itself signs, dangerous temperatures. In addition, the change in position will work on the life and performance of some impact-proof light led lights, 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 explosive gas mixtures, 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. Rated maximum operating temperature of the coil ballast F tω (C), the capacitor's rated maximum operating temperature tc (C), Qinhuangdao explosion led lights | decade integrity Koretoyo explosion | Explosion led lights where the good from Zhejiang Koretoyo proof Electric Co. Tianjin offices. Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (www.tjfangbao.com) is specialized in "proof lighting, explosion-proof motor, explosion-proof distribution box, explosion-proof switch, explosion-proof junction box" business, the company adhering to the "honesty, hard service "concept, to provide you with the highest quality products and services.
