Solar Street Light 2020
Solar street lamps are powered by crystalline silicon solar cells, and with the maintenance-free valve-controlled sealed battery (colloidal battery) for energy storage, ultra-bright LED lamps as light source, and controlled by intelligent charge-discharge controller, used to replace the traditional public electric lighting street lighting.
Solar energy is inexhaustible, inexhaustible, clean and pollution-free and renewable green energy.
Photovoltaic energy is considered as the most important new energy in the 21st century due to its incomparable cleanness, high safety, relative universality and sufficiency of energy, long life and maintainability, and other advantages that other conventional energy sources do not have. Solar street lamps do not need cables, do not need ac power, do not generate electricity; Dc power supply and control ;It has the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economic and practical. It can be widely used in urban main and secondary roads, residential areas, factories, tourist attractions, parking lots and other places.
The solar cell module is usually made of monocrystalline silicon or polycrystalline silicon. LED lamp holder generally adopts high-power LED light source; The controller is generally placed in the lamp pole, with light control, time control, over-charge and over-discharge protection and reverse protection. The more advanced controller has the function of adjusting the lighting time of four seasons, half-power function, intelligent charging and discharging function, etc. Storage battery generally placed in the ground or there will be a special storage battery incubator, can use valve-controlled lead-acid battery, colloidal battery, iron and aluminum battery or lithium battery. Solar led street lamps are fully automatic and do not need to be ditched for wiring, but the poles need to be mounted on embedded parts (concrete bases).
