Bo said the cause of some companies now sell not only street light pole, street lamps, while providing support construction services. 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 LED Chinese knot lights, 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. Metal cable pipe connection should be firmly LED lights purchasing whom Chinese knot home, 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, short sleeve or socket Bands threaded pipe, metal conduit should not be where the production of welded directly LED Chinese knot lights good sealing should be good. 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. Bo cause crop just about one of the most important environmental factors What LED lights good quality Chinese knot, plant photosynthesis, growth and development, morphogenesis and regulation of metabolism and others have, Dutch scholar pointed out that "one percent of the light 1% of the output is "visible importance in crop production. However, the nature of sunlight affected by the weather can not control, so artificial light as an alternative option. Compared to conventional electric light, LED used in modern agriculture has unparalleled advantages and applicability on principle. In recent years, various wavelengths of LED research and application in the field of agriculture has been widespread concern at home and abroad, it has become a new hot spot for LED lighting applications. Currently, artificial light has become an important means of plant production, while artificial light in the plant used in the field before the main high-pressure sodium lamps, fluorescent lamps, metal halide, incandescent and other traditional sources, highlight the shortcomings of these light sources are energy consumption, high operating costs, energy costs accounted for about 50% to 60% of the total operating costs. "Compared to traditional light sources, in addition to the well-known energy-saving features, LED also has a narrow wavelength, light quality pure, high luminous efficiency, rich wavelength type, energy spectrum modulation convenient and low heat, small size, long life and other prominent advantages, easy to focus on Plants desired wavelength implement balanced brachytherapy. "Guangdong Austrian its Andean Technology Co. official said. LED lighting as a plant can be widely used in plant cultivation, greenhouse fill light, plant tissue culture, plant factory, with the promotion of plant growth, regulation of plant morphogenesis, environmental protection and many other advantages. LED lights purchasing whom Chinese knot home | cause | LED lights provided by the Henan Chinese knot 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.
