Lighting design by supporting surface material classification: Indoor proof lighting may be installed in a number belonging to the ordinary combustible material surface proof lights, such as wooden walls and ceilings, they do not allow installation of explosion-proof lighting surface temperature exceeds a safe value. According to whether the explosion-proof lighting can be installed directly in ordinary combustible materials can be divided into two classes surface. One for the only suitable for installation in a non-combustible surface lamps. Another is suitable for direct installation in ordinary combustible materials, surface lighting lamp factory explosion, marked symbols. In addition, according to the installation can be divided into fixed, transportable, and portable. Incandescent although still more use, but due to the low luminous efficiency, shorter life expectancy, is gradually being replaced by other sources. Where the application is a single plug no more starter and self-ballasted fluorescent lamps and high pressure sodium high-pressure mercury lamp. No single plug starter is a cold cathode fluorescent lamp gas explosion-proof lights, emitting principle is the use of a discharge between the electrodes so that mercury atoms produce ultraviolet radiation, thereby stimulating the fluorescent substance luminous tube wall. This high luminous efficiency fluorescent lamps (incandescent about 3 times) proof lamp, long life, no starter when starting (usually in the tube wall of a conductive layer, a layer known as the starter, fluorescent lamps starter is sufficient to complete the proof lights 200w, Koretoyo proof (certified), Hebei explosion proof lights by Zhejiang Electric Co. Koretoyo offices in Tianjin, Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (#) is Tianjin Tianjin City, explosion-proof lighting leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Koretoyo explosion leadership with the staff warmly welcome all inquiries negotiations to create Koretoyo Explosion a better future.
