As the pace of new town development accelerates and road energy-saving upgrades progress rapidly, the demand for solar street lights in rural road energy-saving projects has gradually increased. Supported by government policies, the use of solar street lights has become an important trend in rural road lighting. However, due to differences in geographical locations, the lighting time also varies. So how can we specifically control the lighting time of solar street lights? Here is an introduction from Century Sunshine Lighting.
1. Timing Mode
The solar street lighting system consists of key modules such as solar panels, batteries, and controllers. The controller plays a role in voltage detection, battery charge and discharge management, and controlling the on-off function of the street lights. The turning on and off times of the street lights can be set. The opening time is from late summer to early winter. The on and off times can be configured. This is a universal control mode, where the management personnel only need to adjust the time in the control room according to the regulations.
2. Automatic Mode
Some solar street lights feature an automatic mode, which can be realized through photoresistors or by detecting the panel voltage. A photoresistor is a special resistor whose resistance is closely related to light intensity. The stronger the light, the smaller the resistance; the weaker the light, the larger the resistance. Components such as photoresistors, comparators, and transistors can form a light-controlled circuit. It can turn off the lights when the light is strong and turn them on when the light is weak. Additionally, when the light intensity is high, the output power of the solar panels is greater, and when the light intensity is low, the output power is lower, thereby achieving automatic lighting control.
This concludes our sharing on how to control the lighting time of solar street lights. It is important to note that the timing control mode of solar street lights is the mainstream control mode, which allows for precise control of the street lights’ on and off times and can be adjusted flexibly according to weather conditions; the automatic mode significantly reduces the need for intervention by staff.
