• The difference between LED street lights and ordinary sodium lights

  2020 / 11 / 25

  health LED street lights are free of environmental pollutants such as mercury and lead, and will not pollute the environment. We know that mercury is an extremely toxic substance, but most of the high-efficiency electric light sources currently used contain mercury. According to the study of mercury by Stanford University in the United States, 1 mg of mercury is enough to pollute 5454.5 kg of drinking water. long life The LED light source has a long service life, with a service life of 5-10 times that of traditional lamps. Low carbon Bo Siwei Optoelectronics LED Street Light (120W) = Less use of 298 kg of standard coal per year = 1092 kg of CO2 less emissions per year saving The energy-saving rate of the LED (110W) street lamp of Broadway Optoelectronics is 63% compared with the high-pressure sodium lamp of 250W (system power 300W). It saves 762 kWh/year, which is about RMB 670. Calculated by 5 years of use, it can save electricity costs of 3350 yuan and save traditional lighting supplies by 300 yuan. For new roads, each LED street light can save about cable and transformer costs. 1830 yuan.

• Introduction to Solar Street Lights

  2020 / 11 / 25

  Nowadays, solar energy has become a recognized clean and green energy, and it is gradually applied to people's livelihood to benefit mankind. Among them, solar street lights are one of the solar energy applications. The solar street light system consists of solar panels, controllers, storage batteries or lithium batteries, lamps, light poles, cables and other parts. What is the future of solar street lights? The answer is yes. From the perspective of economic benefits, according to calculations, based on the calculation of 5m street lights and 8m street lights, after adopting solar street lights, 5m street lights and 8m street lights save about 2,290 kilowatt-hours of electricity each year, and the electricity bill saves 1,633 yuan. It has a good profit margin. From the perspective of energy saving and environmental protection, its electricity comes from solar power generation, which does not consume traditional energy, and is energy-saving and environmentally friendly. In the future, the solar street lamp industry will receive support and promotion from many parties due to its obvious social and economic benefits. The market scale of solar street lamps may show a rapid growth trend. When many customers first come into contact with solar street lamps, they always like to search the Internet for solar street lamp manufacturers and their rankings. Since 2005, although solar street lights have been used more and more, especially in the vast rural areas, there are still many shortcomings, so far no large-scale production has been used, so many manufacturers are not For stocking, customers usually place orders, and produce according to customer requirements.

• Types of conventional road lighting poles and lamp arms

  2020 / 11 / 24

  According to the types of lamps used in road lighting design and the height of the poles, road lighting poles can be divided into three categories: conventional poles, medium poles, and high poles. Conventional light poles can be divided into wooden poles, reinforced concrete poles, steel poles and glass fiber reinforced plastic poles according to the material. The poles for medium and high pole lighting are mainly made of steel. The decorative courtyard lamps are summarized and casted by aluminum alloy lamps. Aluminum or cast iron poles, ceramic poles, etc. The lamp arm (frame) on the top of the pole has forms such as single pick, double pick and dobby. The most widely used road lighting is the steel pole, which has the advantages of beautiful, strong and durable. This chapter mainly introduces steel poles. 1. Steel poles can be divided into equal-diameter poles, cones, and polygonal cones. The common typical cross-sectional shapes are hexagons, octagons, and circles. Usually, the whole steel plate is cut and formed by folding at one time. The light pole taper ratio is generally 10‰~12.5‰, using high-quality steel plate such as Q235 type, and the wall thickness is ≥3.5 or 4.0mm. The advantages of the tapered steel pole are reasonable structure, novel and beautiful appearance, and convenient construction and installation. 2. The installation methods of steel poles are divided into three types: direct-buried, flanged and tiltable. The direct-buried type is simple to install. The entire light pole is directly buried in the earth pit, returned to the soil and tamped or fixed by concrete pouring on site. The disadvantage is that the light pole must be re-poured for maintenance and updating. The flange-type light pole is connected by the bottom flange of the light pole and the prefabricated reinforced concrete foundation foot bolts. The installation is extremely simple, and the rep
