Bo said that according to the great cause of national standards, test methods and performance of traditional fluorescent energy saving lamp is tested 2000h and 6000h life light fades. LED lighting products currently CQC energy certification is a measure of 3000h, 6000h and 10000h to judge LED light failure lamp life; while the US Energy Star certification for LED lighting products, light attenuation test minimum requirement is 6000 hours. While these testing methods to detect the actual life situation of the sample, but the test time is too long, the test costs are exorbitant price Zhengzhou Spotlights know how, can not meet the needs of the market. Because unlike traditional lighting technology is relatively mature and stable Zhengzhou largest Spotlights manufacturer, rapid development of LED technology, chip and product appearance products every six months, with great changes have until 6000 hours of light fades test done finished, this product may have been out of the market, so we have to find a faster and more reliable scientific detection methods LED lamps. If the LED lamps cast light as a system, based on the reliability of detection, we can divide it into three subsystems, namely the light source module (module) subsystem, power supply subsystem and interface subsystem. I believe that some of the current research institutes to carry out the overall lighting life accelerated test and then to predict the life of this method is not appropriate. Failure principle and acceleration principle different systems are huge differences, get out of the data is not reliable. Therefore, it should be treated separately according to different subsystems. Bo said the cause of some companies now sell not only street light pole, street lamps cast light Zhengzhou production which company is good, while supporting the construction of the service provided. At this time, if you have such a need, you provided the company with the drawings, the manufacturer will send a site survey to determine the size of the project the amount of quotes, and finished in the newspaper price, and street construction company reached, what you need to pay attention? In this article and you specific description. Manufacturers cooperate in determining the construction, it will be the overall implementation plan street construction. First, according to the construction drawings and site conditions, a pitch designed to determine between lamp post lights installed. Then according to construction plans embedded pipe trench excavation cable, pay attention to the upper part of the cable channel should be slightly higher than the ground, stamped with the production of concrete cover, and no debris to facilitate embedded trench corresponding cable duct. Cable pipe connections, corrosion should be specified. About connecting cable pipe, here are metal and plastic cable ducts points. Short sleeves metal cable pipe connection should be firm, two nozzle should be aligned with the length of the joint should not be less than 2.2 times the outer diameter of the cable pipe, socket, or Bands threaded pipe, metal conduit should not be directly welded seal should be well . Hard plastic pipe at socket or plug, the insertion depth should be 1.1 to 1.8 times the inside diameter of the pipe. The docking surfaces should be coated with glue cement seal, using socket casing ends should be closed when welding. Zhengzhou floodlight factory production strength _ cause (certified) _ Spotlights provided by the Henan cause Bo Lighting Equipment Limited. Henan cause Bo Lighting Equipment Co., Ltd. (www.zzdybcdj.com) is Zhengzhou City View light fixtures leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the cause of the leadership with the staff warmly welcome all inquiries negotiations to create the great cause of a better future.
