When the tube rupture starter layer have been destroyed, light that is off), low (about 200 ℃) cathode temperature, is a safe and practical light source, very suitable into increased safety lighting. Eco-friendly self-ballasted high pressure mercury lamp light source is the use of high-pressure mercury vapor discharge and mixed light lamp incandescent body and the phosphor emits light three substances. It has high brightness, simple structure, start fast and so on. Shortcomings in the past to change the high pressure mercury lamp ballasts needs additional use of tungsten to play a limiting role, but also to improve the light color. The disadvantage is relative to the normal fluorescence lifetime to shorten some of the high-pressure mercury lamp. HPS is a high-pressure sodium vapor discharge lamp, explosion-proof lamps wholesale, high luminous efficiency, low power consumption, strong fog penetrating capacity, long life and other advantages of the explosive properties of grade, accurate selection of lamps explosion category, type, level and temperature class. Read the product manual, to understand product performance, precautions and limitations of the product, understand the content of the product of all flags. As proof certificate number after the "x" symbol, indicating that the lamp has a particular application space, Wuqing proof lighting, should consult the product manual and nameplates, specifically applicable site requirements. AⅠ class - the basic insulation on the basis of how much money explosion-proof lighting, the conductive parts accessible during normal operation are not charged to the fixed line connecting the protective ground conductor. BⅡ class - with double insulation or reinforced insulation as a safety measure, no ground protection. CⅢ class - with a valid value not greater than 50v safe voltage, explosion-proof lighting where there is, and where no higher than this value. D0 class - only rely on basic insulation as a safety measure. Most of explosion-proof lighting protection against electric shock Class I type lamps, only a small number of class Ⅱ, Ⅲ type lamps. For example: plastic explosion-proof lighting, explosion-proof flashlight. Proof lighting agents, professional well-known manufacturers Koretoyo explosion, explosion-proof lighting by Zhejiang West Green Koretoyo explosion-proof electrical Co., Ltd. Tianjin offices. Zhejiang Koretoyo explosion-proof electrical Ltd. Tianjin Office (www.tjfangbao.com) is Tianjin, 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 . Explosion in Koretoyo leadership with the staff warmly welcome all inquiries negotiations to create Koretoyo better future proof.
