Solar sensor wall lamp

• Charging Phase: During the day, the solar panel of the solar wall light absorbs solar energy. By using the photovoltaic effect, it converts solar energy into direct current. Then, through the charge controller, it charges the built - in battery to store electrical energy.
• Lighting Phase: When night falls and the ambient light weakens, or when an emergency causes the interruption of normal lighting, the light - controlled sensor or the emergency - sensing device will be triggered. The charge controller then switches the power supply mode, enabling the battery to supply power to the light source of the lamp, thus achieving the lighting function.

Advantages

• Energy - Saving and Environment - Friendly: It utilizes clean energy from the sun, without consuming traditional fossil fuels, which reduces carbon emissions and is environmentally friendly. Moreover, it charges during the day and lights up at night, eliminating the need for additional consumption of mains electricity. Long - term use can save electricity costs for users.
• Convenient Installation: There is no need to lay complex wires and cables. Just fix the wall light in a suitable position on the wall, ensuring that the solar panel can receive sufficient sunlight. This installation method is simple and quick, suitable for various places, especially those areas where large - scale wiring is inconvenient.
• Safe and Reliable: It adopts low - voltage direct - current power supply. Compared with traditional mains - powered lighting, it greatly reduces the risk of electric shock. Additionally, since it is independent of the mains power grid, in case of power grid failures, natural disasters, etc., it can still ensure reliable lighting, providing safety protection for people.
