As an important energy source for the development and utilization of new energy at this stage, solar energy is an important development direction of the world's energy utilization and can effectively reduce the consumption of conventional energy. With the adjustment of China's energy structure, new energy sources continue to replace old energy sources. At the same time, due to the national infrastructure construction investment and the development of solar cells and light-emitting diode lighting technology, the photovoltaic lighting market has ushered in an explosion period, and the solar street lamp market has a broad prospect.
Generally, solar street lights are mainly composed of solar panels, battery panel brackets, photovoltaic controllers, batteries, LED lamps, and hot-dip galvanized light poles. The solar street light adopts a modular integrated design. The lightweight lithium battery and the controller are integrated into the lamp, which is convenient for installation and maintenance. The patented lens bat-shaped light distribution makes the light distribution more even.
Through the scientific lens, the uniform distribution of light is realized, and the illumination range and height are wider and higher. The illuminance is 100% higher than that of traditional solar street lights, which can easily cope with the needs of different scenarios.
Most solar street lights use LED light sources because they can reduce energy consumption. The most important thing is that LED light sources have a long service life, but in addition to their own conditions, their service life is also affected by external factors. If you want to increase the service life of the LED light source, you should pay attention to its heat dissipation and constant current. A good heat dissipation function is the basis for controlling the internal temperature of the lamp. Keeping the internal temperature of the lamp constant can prolong the service life of the LED lamp beads.
Solar street lights use hot-dip galvanizing as the pole technology, and at the same time carry out electrostatic spraying, to ensure the life of the pole, anti-corrosion and anti-rust. Achieve good waterproof, anti-corrosion and anti-oxidation effects to extend the service life of street lights. The appearance of hot-dip galvanizing is slightly rougher than that of cold-dip galvanizing, and it is silvery white, and the appearance is prone to process water lines and a few drips, especially at one end of the workpiece. However, the slightly rough hot-dip galvanized zinc layer is dozens of times thicker than electro-galvanized, and its anti-corrosion performance is also dozens of times that of cold galvanized.
Solar street lights use lithium iron phosphate batteries, which have a long service life and can reach more than 1,000 deep cycles. The volume of lithium batteries with the same capacity is about two-thirds of the volume of colloidal batteries and the charging efficiency is longer.
Solar street lights use MPPT controller, and the maximum power generation efficiency is 25% higher than traditional solar street lights. After the protection of the lithium battery protection board is cut off, the controller can be charged through the solar panel; and it has a four-time control function, and the user can set the LED lights by themselves The working current to achieve intelligent control.
