Solar street light is a very good and promising type of street light. It is the most widely used type of road on the market. We usually see that our street light will automatically turn on at a certain time. By what principle has the principle been achieved? Today, Jiangsu New Era Lighting will introduce some features and selection issues of our
solar street light controller for everyone to understand. How to control solar street light—features of solar street light controller Guarantee current and constant current output Because the LED itself needs to carry out constant current or current limiting through technical means, otherwise it will not work properly at all. The general method of LED solar street light is usually to add a driving power supply to carry out the constant current of the LED, but this requires a power loss, which makes the addition of an independent driving power supply more power consumption, so this method is not very suitable. desirable. Control the output period The solar controller can set the time period, and the output current starts to work when the set time period is reached. Adjustment of output power In the application of solar street light, the power is adjusted. Adjusting the power can control the brightness of the LED solar street light. For example, the street light can be adjusted to 30W in the early morning and 15W in the middle of the night to save energy. This locks the current to meet the lighting needs at night, and saves the overall configuration and budget of batteries and solar panels. It can also greatly effectively extend the life of LED solar street light. How to control solar street light - how to choose solar street light controller Controllers that consume less than 1 mA. 2. To choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the battery panel, especially in winter or periods of insufficient light, the MCT charging mode is about 20% more efficient than others. 3. A controller with two-way power regulation should be selected. The controller with power regulation has been widely promoted. During the night when there are few pedestrians, one or two lights can be automatically turned off to save electricity. It can also be used for LED solar street light. Power regulation. In addition to selecting the above power-saving functions, you should also pay attention to the protection function of the controller for components such as batteries. For example, the controller with trickle charging mode can protect the battery well and increase the life of the battery. In addition, set the controller undervoltage protection. When the value is set, try to adjust the under-voltage protection value to ≥ 11.1V to prevent the battery from being over-discharged. The above are some of the options and features of our solar street light controller that Yangzhou Global Solar introduced to you. It can be seen that our solar street light generally realizes automatic switching. I hope you can understand. The solar street light controller is a very important issue, and everyone must pay special attention to it.
