Analysis of solar street light structure
December 08, 2020
Solar street light is an intelligent control system. The solar street light system is composed of several parts, including LED lamp holder, solar lamp controller, battery (including battery incubator) and light pole. Solar cell components generally use monocrystalline silicon or polycrystalline silicon solar cell components; LED lamp holders generally use high-power LED light sources; controllers are generally placed in the light pole, with light control, time control, overcharge and overdischarge protection, and reverse connection protection. Advanced controllers are also equipped with functions of adjusting the lighting time in four seasons, half power functions, intelligent charging and discharging functions, etc.; batteries are generally placed underground or there will be special battery incubators, which can use valve-regulated lead-acid batteries, gel batteries, Iron-aluminum batteries or lithium batteries, etc. The solar lamps work fully automatically and do not need to dig trenches for wiring, but the poles need to be installed on the embedded parts (concrete base).
Description of the working principle of solar street lights: solar street lights during the day are under the control of the intelligent controller, the solar panels absorb solar light and convert it into electrical energy under the control of the intelligent controller. The solar battery modules charge the battery pack during the day, and the battery pack provides power to the LED at night The light source is powered to realize the lighting function. The DC controller can ensure that the battery pack is not damaged due to overcharging or overdischarging. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
