Solar street lights, as an energy-saving and environmentally friendly lighting facility, have received a strong market response since their promotion. Due to their electricity-free nature and convenient installation and maintenance, they have been favored by customers across the country, especially in vast rural areas undergoing development and construction. The main reason for the popularity of solar street lights lies in their intelligent control system, which can automatically control the on and off of the lights using solar energy.
Solar street lights have four intelligent control methods for turning on and off the lights. The best one is the light-controlled switch: When the light intensity drops below a certain value in the evening, the control unit senses the weakening of light and sends a signal to automatically turn on the light source. When the light intensity rises above a certain value in the morning, it sends a signal to automatically turn off the light source;
The second method is the light-controlled on-time-controlled off approach, which is similar to the first method. When the light intensity drops below a certain level in the evening, the light source automatically turns on and starts timing. When the preset turn-off time is reached, the light source automatically turns off. This approach is mainly suitable for areas where there is little variation in light intensity between morning and evening.
The third type is the time-controlled system for dawn-dusk operation: when the light intensity drops below a certain level in the evening, the solar streetlight source automatically illuminates; when the preset turn-off time is reached, the light source automatically turns off; in the wee hours, when the preset turn-on time is reached, the light source automatically illuminates; and when the light intensity rises above a certain level in the morning, the solar streetlight automatically turns off again. This is the intelligent way in which solar streetlights turn on and off.
The fourth type is dual-channel control of main and auxiliary lights: the light source is divided into two channels, namely the main light and the auxiliary light. When the light intensity drops below a certain value in the evening, the light source automatically turns on, and both the main and auxiliary lights can be controlled separately for turning off time, allowing for different working modes of the main and auxiliary lights to be combined.
