1. What street lights are Solar street lights

Solar street lights use crystal silicon Solar batteries to power. The maintenance valve controlled sealing battery (collagen battery) storage electricity is stored. The ultra -high -bright LED lamps are used as a light source and controlled by intelligent filling controller. It is used to replace traditional public power lightingStreet Lights.Solar street lights are composed of several parts such as LED light sources, Solar cell panels, batteries, battery insulation boxes, Solar street light controllers, street lights, and auxiliary materials wires.

The working principle of Solar street lights is: Under the control of intelligent controllers, Solar cell panels absorb Solar light during the day and convert into electric energy, charge the battery pack, and provide electricity to the LED light source to power the LED light source at night.Electricity can be stored to ensure the normal work of rainy weather.

2. How much is a set of rods in Solar street lights?

The price of Solar street lights is affected by factors such as the height of the light pole, the light of the light head, the power of the power, the length of the lighting time., Lantern flange sleeves, basic embedded parts and built-in wires, ranging from about 2500-1000 yuan according to the configuration.For example, a 6 -meter -high, 30 watts of Lights, and 6 hours of light per day.
