Features and selection method of LED solar street light controller

November 13, 2020

LED solar street light is a very good type of street light for us, and it is the most widely used road type on the market. Then we usually see that our street light will automatically light up at a certain time, then what exactly does it pass? The principle has reached the principle? Today, street light manufacturers will introduce some of the characteristics and selection issues of our LED solar street light controllers for everyone to understand.

Ensuring constant current output Because the LED itself needs to be constant current or current limited by technical means, otherwise it will not work properly. The general method of LED lights is usually to add a driving power supply to carry out the constant current of the LED, but this requires a loss of power, which makes the addition of an independent driving power more power consumption, so this method is not desirable.

Control the output time 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 lights, the power is adjusted. Adjusting the power can control the brightness of the LED lights. For example, the street light can be adjusted to 30W in the early morning and 15W in the late night to save energy. This locks the current to meet the lighting needs at night, and saves the overall configuration and budget of the battery and solar panels. Greatly and effectively extend the life of LED lights.

1. The controller with lower power consumption should be selected. The controller works 24 hours a day. If its own power consumption is large, it will consume part of the power. It is best to choose a controller with a power consumption of 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 when the light is insufficient, the MCT charging mode is about 20% higher than other efficiency.

3. The controller with two channels of power regulation should be selected. The controller with power regulation has been widely promoted. It can automatically turn off one or two channels of lighting at night when pedestrians are scarce, saving electricity, and can also adjust the power of LED lights. . In addition to selecting the above power-saving functions, you should also pay attention to the controller's protection function for the battery and other components. For example, the controller with trickle charging mode can protect the battery well, increase the battery life, and set the controller under-voltage protection. When setting the value, try to adjust the undervoltage protection value to ≥ 11.1V to prevent the battery from over-discharging.

The above are some of the options and features of our LED solar street light controllers introduced by landscape light manufacturers. It can be seen that our LED solar street lights generally realize automatic switching, and I hope everyone can understand. LED solar street light controller is a very important issue, everyone must pay special attention to it.
