Working principle and composition of
solar street light Solar street light utilizes the principle of photovoltaic effect of solar cells. During the day, solar cells absorb solar photon energy to generate electricity, which is stored in the battery through the controller. When night falls or the illumination around the lamp is low, the battery passes through The controller will cut off the power supply to the light source after the set time. The composition of solar street light The solar street light is mainly composed of the following parts: solar cell components, component brackets, solar controllers, batteries, light sources, light poles (including lamps), etc. Controller Regardless of the size of the solar luminaire, a charge and discharge controller with good performance is essential. In order to prolong the service life of the battery, its charging and discharging conditions must be limited to prevent overcharging and deep charging of the battery. In places with large temperature difference, a qualified controller should also have temperature compensation function. At the same time, the solar controller should have both street lamp control functions, light control and time control functions, and should have the function of automatic load cutting at night, which is convenient for extending the working time of street lamps in cloudy and rainy days. This controller is specially designed for solar-powered DC street lamps, with light control start + timing delay shutdown. Timing shutdown time can be adjusted; with short circuit, overload, unique anti-reverse connection protection and full-function protection measures such as full, over-discharge automatic shutdown, charging indication, fault and over-discharge indication. Special maintenance-free storage for solar energy Because the input energy of the solar photovoltaic power generation system is extremely unstable, it is generally necessary to configure a battery system to work. Generally, there are lead-acid batteries, Ni-Cd batteries, and Ni-H batteries. The selection of battery capacity generally follows the following principles: first, on the premise that it can meet the night lighting, the energy of the solar cell components during the day should be stored as much as possible, and at the same time, the electric energy should be able to be stored to meet the continuous cloudy and rainy night lighting needs. The battery capacity is too small to meet the needs of night lighting, and the battery is too large. The light source used by the light source battery is an important indicator of whether solar lamps can be used normally. Generally, solar lamps use low-voltage energy-saving lamps, low-pressure sodium lamps, electrodeless lamps, and LED light sources.
