The design of the solar led street lamp controller integrated solar street light

Design including solar street lamps light source, solar battery, storage battery charging and discharging control, etc. , any one link problems will cause defects. Solar street lamps by solar panels, charge and discharge controller, storage battery shell, load and lamps and lanterns five



the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Design including the light source, solar cell' Solar cells can effectively absorb solar energy and convert it into a power semiconductor components. 】 System, storage battery charging and discharging control, etc. , and any one link problems will cause defects. Solar street lamps by solar panels, charge and discharge controller' This controller is intelligent to adjust the working voltage of solar panels, always work in V - making solar panels A characteristic curve of maximum power point. 】 Shell, battery, load and lamps and lanterns of five parts, we to the charge and discharge controller introduced below. Regardless of the size of the solar street lamps, a good performance of charge and discharge control circuit is necessary. In order to prolong the service life of the battery, prevent a battery charging and depth discharge is essential. In addition, because the solar photovoltaic power generation system of unstable input energy, photovoltaic power generation system for battery charging control than normal battery charging control is more complicated. Solar street lamps design success often depends on the success and failure of control circuit of charging and discharging. Don't have a good performance of charge and discharge control circuit, is impossible to have a good performance of solar street light. Charge and discharge controller must have the following characteristics: the counter-attack charging control, prevent charging control, prevent discharge control, temperature compensation.
