When solar stree light is turned on, it is turned off. The main working method of the solar street light is that the light is turned on and turned off. The principle of light control is that the solar panel is a photoreceptor that can generate different voltages and currents according to different light intensities. The stronger the light, the higher the voltage, the weaker the light, and the lower the voltage. In this way, the manufacturer sets the voltage value corresponding to the darkness as the voltage to turn on the lights. Every time it gets dark, the street lights turn on automatically. Time-controlled off is because a countdown is set in the controller program to turn on the dark light, the countdown clock starts to trigger, the power is automatically changed when the preset time period is reached, and the light source is turned off when the preset light-off time is reached.

●Pure light control Pure light control means that the light is controlled to turn on the light, and the light is controlled to turn off the light. The light source works overnight.

●Morning light Morning light means turning on the lights before dawn in the early morning, usually set for 1-2 hours, to illuminate people who get up early in the morning. The turn-on time of the morning light will automatically advance or delay with the change of seasons. However, in the first week or so after the installation of the street lights, the ones that are bright in the morning may not work normally, because the system is learning (detecting records) the time of dawn every day, and then calculating the average, and finally getting the time of dawn and pushing it back to the preset time to start lighting up. The morning three is generally added after the light-controlled opening and the time-controlled closing, and used together.

●Period The controller generally has 4 periods (some controllers have 3 segments, 5-6 segments), that is, the whole night is divided into 4 segments, each segment can be adjusted with different duration and different brightness. In this way, we can make the light source work with different brightness during the peak period, the second peak period, the trough period and the sporadic flow period, which can save energy to the maximum extent while meeting different lighting needs.
