Do you have a 2 meters high solar street light

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,

a solar led street light is made up of six basic parts: solar energy battery components and bracket, battery, charge and discharge controller, light source, light pole lights, cable and connection fastening accessories. In the design of solar led street light, there are many links, 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. For silicon cells, the standard under the condition of 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. Monomer solar cells are usually not available, but the solar cell module is actually used. The solar cell is directly proportional to the logarithm amplitude with the sun of the intensity of illumination, and has a negative temperature coefficient. When temperature rises once, voltage drop in 2 ~ 3 mV mV. The solar cell ( Components) The output power depends on the sun illumination, amplitude spectral distribution and solar cells ( Components) The working temperature. In different time and place, the same power output of the solar cell is different. 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 power of light source, the use of time and to determine the local climate and geographic conditions. For any solar led street lamp system, the merits of the charge and discharge control circuit will directly affect the success or failure of the system application. Unstable as a result of the solar photovoltaic power generation system input energy, photovoltaic power generation system in the battery control is more complex than ordinary batteries. 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, over discharge protection, short circuit protection and reverse connection protection, regulating function and automatic switching 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. Because the solar lighting system directly by solar batteries, batteries of unstable energy, so it is necessary to configure reasonable and reliable performance of the battery capacity, in order to ensure the normal operation of photovoltaic power generation system. In solar photovoltaic lighting systems, usually use maintenance-free lead-acid batteries. Maintenance-free lead-acid battery is a new type of battery, adopts fully sealed method, high discharge rate and stable features; Do not add water; Installation is simple, cover an area of an area small, the horizontal and vertical installation; 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. Currently, most solar lawn using light-emitting diode as light source. Led life of up to 100000 hours, 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. The voltage of DC DC energy saving lamps, no inverter, convenient and safe.
