A solar led street light by solar energy battery components and bracket, battery, charge and discharge controller, light source, light pole lamps, cables and connection of fastening accessories and so on six big basic parts. Involved in the design of solar led street lamp, solar energy battery components,

by solar energy battery components and solar led street light bracket, battery, charge and discharge controller, light source, light pole lights, cable and connection of six basic parts fastening accessories. In the design of solar led street lamp, involves many aspects, such as solar cell components, battery, charge and discharge controller, light source, etc. Any question any link will lead to defective products. Solar cells convert solar energy into electricity using photovoltaic (pv) effect. In the standard conditions, the silicon battery open circuit voltage is 0. 48 ~ 0. 6V。 More than a single solar cells are connected and packaging in order to form with different area and different power of the solar cell module, it can also be referred to as solar panels. A single solar cell usually is not available, but is actually used the solar cell module. Solar cells and the sun is directly proportional to the logarithm amplitude intensity of illumination, and has a negative temperature coefficient. Every time a temperature rise, voltage drops 2 ~ 3 mv. The solar cell ( Module) The output power depends on the sun illumination, amplitude spectral distribution and solar cells ( Module) The working temperature. The same power output of the solar cell is different in different time and different locations. Not, as some people think that as long as there is sunshine, there will be rated output power, even think that the solar cell can be used in normal light. Per square meters area computation, the output power of solar cell is about 120 watts. With the improvement of conversion efficiency, the output power also increases accordingly. The solar modules output power should be selected according to the solar lamp light source power, use of time, and to determine the local climate and geographical conditions. For any solar led street lamp lighting system, the merits of the charge and discharge control circuit will directly affect the success or failure of the system application. As a result of the solar photovoltaic power generation system input energy extremely unstable, the battery in the photovoltaic power generation systems control charging control is more complicated than normal ones. Good performance of the photovoltaic controller should have a variety of protection functions, such as the battery charge and discharge control, temperature control, maximum power tracking and over charging protection, discharge protection, short circuit protection, reverse connection protection, automatic regulating function switch and time. So as to ensure the reliable operation of the system, make the solar cell components under different temperature and irradiation intelligent maximum power output, make the lighting system with high efficiency. As a result of the solar lighting system battery charging directly provided by the solar cell, the unstable energy, therefore should configure reasonable and reliable performance of the battery capacity, in order to ensure the normal operation of photovoltaic power generation system. In the solar pv lighting system, usually choose maintenance-free lead-acid batteries. Maintenance-free lead-acid battery is a new type of battery. Adopts fully sealed method, flow rate is high, stable performance. Don't need to water; Installation is simple, cover an area of an area small, can be installed in horizontal and vertical. The average life expectancy for 5 ~ 7 years old. Solar led street lamp has the advantages of energy conservation and environmental protection. The load should be energy saving, low consumption, long life. Semiconductor light-emitting diode lamp, 12 v DC energy saving lamps, low voltage sodium lamp, high-pressure sodium lamp and electrodeless induction lamp can be used as a solar lamp light source. At present, the light-emitting diodes (leds) are widely used as solar lawn light. The light-emitting diodes (leds) more than 100000 hours service life, low work voltage, very suitable for application in solar energy lawn. Solar garden light with led light source and 12 v DC energy saving lamps. Voltage of DC DC energy saving lights, no inverter, convenient and safe.
