Custom LED Wall Washer Light are based on the principle of photovoltaic effect of solar cells. During the day, solar cells absorb solar photon energy to generate electric energy, which is stored in the battery through the controller. When night falls or the light brightness around the lamps is low to a certain value, the controller will discharge and turn on the street lamps to start lighting.

Precautions for use of led street lamps

1. The LED street light device shall be installed in sunny days at all times. If it is installed in rainy days, it will only consume electricity without charging after lighting up, which will fail to meet the demand for description. The LED street light device shall not be lit on the day when it is finished.

2. The view point of the LED street lamp battery panel is usually depicted by the manufacturer at a 45 degree tilt angle, so as to ensure a better charging capacity in winter.

3. The connection of led street lamp controller. The waterproof controller shall be used as far as possible to ensure long-term stability and prevent users from changing the lighting time at will. If a non waterproof controller is used, the wiring is bent into a U shape because the terminal is facing down, which can prevent water from pouring into the controller from the line.
