Solar-powered outdoor devices integrate solar power, LED lighting, and advertising displays. Their core advantages are the absence of an external power grid, flexible installation, and energy efficiency.

1. Solar Panel: Absorbs sunlight during the day and converts it into electricity, providing the device with energy. Commonly made of monocrystalline silicon, they offer a high conversion efficiency of 23% and are adaptable to varying lighting conditions.

2. Energy Storage Battery: Stores the electricity generated by the panels for use at night or on cloudy days. Lithium batteries are the most popular choice due to their lightness and long lifespan. The choice should be based on the application scenario.

3. Control System: This is the core component responsible for managing charging and discharging (to prevent overcharging and overdischarging of the battery), controlling the LED lighting on/off/brightness, and adjusting the display of advertising images (such as scrolling and switching).

4. Light Box Body: Contains the LED light source (providing both lighting and advertising backlighting) and the advertising display area (which can accommodate posters, scrolling images, or LED electronic screens). The outer shell is typically constructed of aluminum alloy or galvanized steel, providing waterproof and sun-resistant properties.
