Yufai: Is there no street light controller for 100w led solar street light?

In recent years, the country has begun to promote energy conservation and environmental protection, and solar new energy street lights are also under construction. 100w led solar street lightwill become the choice of road lighting energy-saving transformation. Its characteristic advantages are easy installation, low maintenance cost, long service life, and wide range. Used in rural and urban areas, solar street lights can be divided into solar panels, batteries (divided into lithium batteries and gel batteries), controllers, light poles, lamp holders, etc. The controller is an important component. The following editor analyzes why solar street lights need a controller to light up? Why do street lights need a controller to light up?

1. Control

Under normal working conditions, when the solar panel charges the battery through the street light controller, the controller automatically detects the charging voltage. At this time, the smart chip in the solar controller will control the output voltage of the street lamp, so as to control the street lamp light.

2. Boosting effect

Under normal working conditions, when the street light controller cannot detect the output voltage, the controller controls the output voltage of the output terminal. At this time, if the battery voltage is 12 volts, the normal light demand requires 18 volts. In order to meet the requirements of the input voltage of the light source, the controller will increase the voltage. At this time, the street light controller must be able to achieve lighting.

3. Stabilizing effect

When the 100w led solar street light battery board is charging the battery, its voltage is very unstable. If the battery is charged directly, the battery life or damage will be reduced. At this time, the regulator function of the controller will limit the input battery voltage with a constant voltage. When the battery is sufficient, it will charge its small current or not.
