The future is an era of scarce resources, so we are all looking for new alternative energy-saving and environmentally-friendly new energy sources. Nowadays, solar energy products can be seen everywhere in our lives, such as solar water heaters, solar power stations, etc. The more common ones are solar street lights. As a new energy-saving and environmentally-friendly new energy product, it is becoming more and more popular.
Solar street lights use crystalline silicon solar panels to achieve photoelectric conversion, and then store the converted electrical energy in a maintenance-free valve-regulated sealed battery (gel battery or lithium battery), super bright LED lamps as the light source, and intelligent charging Discharge controller control, used to replace traditional public electricity lighting street lights. It avoids the requirements of laying cables and no need for AC power supply. At the same time, because it uses solar photoelectric conversion to achieve lighting, no electricity bills will eventually be generated; it is completely DC power supply and control; it has good stability, long life, high luminous efficiency, and easy installation and maintenance , High safety performance, energy saving, environmental protection, economical and practical advantages. It can be widely used in urban main and secondary arterial roads, communities, factories, tourist attractions, parking lots and other places.
Solar street lights are composed of LED light sources, solar panels, lead-acid batteries or lithium batteries (including battery incubators), solar street light controllers, and street light poles (including basic ground cages).
The solar cell module is a charging and discharging system composed of solar panels and storage batteries. Generally, monocrystalline silicon or polycrystalline silicon raw materials are used as the raw materials of solar panels. Usually, the photoelectric conversion efficiency of solar panels made of monocrystalline silicon is better than that of polycrystalline silicon solar panels. Solar panels, at the same time, because of their high conversion efficiency and complicated process, their cost is relatively high, and the price will be higher than that of crystalline silicon.
LED lamp holders generally use high-power LED light sources. Generally, we use a 1W white LED light source arranged side by side on the circuit board, through welding, assembling, and installing the lamp housing to finally form the finished lamp holder we need. The power of the lamp holder is based on the requirements of the customer's order. For actual production.
The controller is generally placed in the light pole, with light control, time control, overcharge and overdischarge protection and reverse connection protection, adjustment of the lighting time function, half power function, intelligent charging and discharging functions, etc.; lead-acid batteries due to their large size and weight Heavier, generally placed underground or there will be a special storage battery incubator, externally sealed with cement, basically no maintenance, except for maintenance when replacing, and lithium batteries are generally placed because of their small size and light weight. The battery rack under the bracket of the solar panel is located at the top of the light pole, which also avoids the possibility of theft due to its high price.
For the light pole part, I generally use Q235 steel plate for folding production. The thickness of the steel plate is determined according to the height of the light pole and related standards. The rolled steel plate is welded, polished, hot-dip galvanized, Follow-up finishing such as spraying and baking, and finally forming, become the finished product we need.
The installation of solar lamps is easy and convenient, and there is no need to dig trenches for wiring. The depth and width specified by the standard are dug in advance, and the corresponding ground cage foundation is placed in it, and it is poured with cement. After assembling the other parts, install the flange at the bottom of the light pole on the embedded part (concrete base), fix the light pole, and the installation is complete.
