Choose Solar Powered Street Lamp Controller
The solar powered street lamp controller is the core component of the entire solar street light system, so the quality of the solar street light controller directly affects the life of the entire solar street light system, and has a great impact on the lifespan of the battery.
The following three points should be considered when choosing a solar powered street lamp controller:
1. First, there must be complete protection functions, such as battery charging over-voltage protection, discharge under-voltage protection, reverse connection protection, LED output short-circuit protection, lightning protection and other protection functions.
2. The higher the charging efficiency of the solar powered street lamp controller and the efficiency of constant current driving LED lights, the better. The high charging efficiency can save solar panels and charging time. The high efficiency of driving the LED lamp with constant current can save battery power. The overall realization is more energy-saving and environmentally friendly.
3. It must have light control function, three-stage time control function, dimming function, and be able to drive LED lights intelligently.
a. Light control function: When the solar panel receives sunlight, the solar panel battery reaches a certain voltage and then starts the voltage, the LED street light turns off, and the solar panel starts to charge the battery. Otherwise, the LED light is on and the battery discharges.
b. Time control function: Generally, it is a three-stage time control function, which can realize the setting of LED lights in three stages, each lighting for a few hours, generally 3 hours + 3 hours + 2 hours configuration, a total of 8 hours. The lighting hours can be set, of course.
c. Dimming function: It is possible to set the brightness of the LED light. For example, the brightness of the LED light can be set to 100% in the first period of 3 hours, the brightness of the LED lamp in the second period of 3 hours is 50%, and the brightness of the LED lamp in the third period is 30% for 2 hours, which can save energy effectively.
Performance is the first point that many people would consider when purchasing cost effective solar powered street lamp. What factors will affect the price of the controller?
