Yes, the solar trash can light box is an advertising carrier that has sprung up in major cities in China in recent two or three years. Many urban management departments often require media companies to build trash cans into solar trash can light boxes to respond to the requirements of energy conservation, environmental protection, efficiency and emission reduction.
In fact, there is nothing mysterious or scientific about this product. Yunnan Langpu is a relatively large-scale garbage can and light box manufacturer in Yunnan, Guizhou and surrounding areas. Simply put, it is the combination of traditional trash can+advertising light box+solar street lamp lighting power supply system.
If you want to provide wifi information, add a wifi signal transmitter to provide a certain network bandwidth.
However, when installing the solar trash can light box in the city, we must pay attention to the design of the solar panel bracket, try to choose a solar panel that is close to the square, and make the solar panel rotate to face the sunlight, so that the incident angle of the sunlight on the solar panel is close to 90 degrees. It's a pity that many manufacturers don't understand the working principle of solar panels, and fix them, making the solar power supply system a decoration.
The above (brown) is unreasonable, because the solar panel is fixed and cannot be adjusted to aim at the sunlight; The following model (black and white) can rotate within a certain range and aim at the sun through the sleeves of large and small tubes, so that no matter how the street goes, the solar panels can be adjusted to aim at the sun.
