Characteristics and Selection Methods of LED Solar Street Lamp Controller

Safeguard current constant current output Since the LED itself needs to be constant or currently flowing through technical means, it will not work at all. The general LED light uses the way is usually plus a driving power supply to perform the constant current of the LED, but this requires a power loss that makes it more powerful than the independent drive power supply, so this method is not preferable.

The control output time period solar controller can set the time period, and the output current starts working in the set period of time.

The adjustment of the output power is adjusted to the power in the application of solar street lamps. Adjusting power can control the brightness of the LED lamp, such as the early morning light adjustment to 30W, late night to adjust to 15W energy conservation, so that the current is only satisfied with nighttime lighting demand, and saves the battery, solar panels, the overall configuration and budget, can also It is greatly effective to extend the life of the LED lamp.

1. Should choose a low power consumption controller, the controller is not intermittently operated 24 hours, such as its own power consumption, it consumes some power, it is best to select the controller of power consumption at 1 mAfter.

2. To select a controller with high charging efficiency, the controller with the MCT charging mode can automatically track the maximum current of the panel, especially during the period of winter or lack of light, and the MCT charging mode is more than about 20% higher than other high.

3. The controller with two adjustment power should be selected. The controller with power regulation has been widely promoted. You can automatically close all the way or two lighting in the rare period of the night. . In addition to selecting the above power saving function, you should also pay attention to the control of the controller to the protection of the battery, like a controller with trickle charging mode, can protect the battery, increase the life of the battery, and set the controller undervoltage protection. Try to adjust the undervoltage protection value when value≥11.1V to prevent the battery from being overlapping.

The above is some of the characteristics of the LED Solar Lights Controller for everyone. It can be seen that our LED solar street light is generally automatic switch, I hope everyone can understand. LED solar street lamp controller is a very important issue, everyone must pay special attention.
