1. The constant current output of the LED itself requires constant current or current limiting through segments, otherwise there is no constant operation at all. The general method of selecting LED lights is usually to add a driver power supply to maintain the constant current of the LED, but this requires power loss, which leads to additional power consumption of the driver power supply. Therefore, this method is not recommended.

2. The solar street light controller can set the time period for controlling the output period, and when the set time period is reached, the output current begins to operate.

3. The adjustment of output power is used in the application of solar street lights to adjust the power. Adjusting the power can control the brightness of LED lights, such as adjusting the street lights to 30W in the morning and 15W in the late night,

This locks in the current, which not only meets the lighting needs at night, but also saves the overall equipment and budget of batteries and solar panels, and can greatly prolong the lifespan of LED lights.

1. A solar street light controller with lower power consumption should be selected. The controller operates continuously 24 hours a day. If its own power consumption is high, it will consume some electrical energy. It is better to choose a controller with a power consumption of less than 1 milliampere.

2. Choose a controller with high charging efficiency. A controller with MCT charging form can actively track the high current of the battery board. In winter or periods of low light, the efficiency of MCT charging form is about 20% higher than other forms.

3. A controller with two channels of power conditioning should be selected. A controller with power conditioning has been implemented, which can actively turn off one or both channels of lighting during nighttime pedestrian hours, saving electricity, and can also adjust the power of LED lights.

In addition to selecting energy-saving functions, attention should also be paid to the maintenance function of the controller for components such as the battery. For example, controllers with trickle charging can maintain the battery and increase its lifespan. When setting the undervoltage maintenance value of other controllers, it is best to adjust the undervoltage maintenance value to ≥ 11. 1V, battery over discharge.
