Problems solved by technology

[0002] Walkway lights are an important part of urban landscape and residential area lighting. Traditional walkway light sources usually use high-pressure sodium lamps, which consume a lot of energy and have low luminous efficiency. The disadvantages cause a huge waste of energy, which is not conducive to the construction of green and environmentally friendly cities.
