Solar lighting, an application of photoelectric conversion technology, represents a significant development in new energy. It offers advantages such as energy conservation, environmental protection, safety, no wiring required, simple installation, intelligent control, and the ability to relocate as needed. It has strong scalability in cities facing severe energy shortages and power outages, as well as in remote areas where electricity access is difficult. Currently, solar lighting systems are developed based on national conditions and public opinion, offering high cost-effectiveness. The main types of solar lamps include solar street lights, solar garden lights, solar lawn lights, solar landscape lights, and solar signal lights.

Currently, the most popular are integrated solar street lights. These do not require pre-installed cabling. They actively absorb sunlight and convert it into electricity. Compared to conventional street lights, they have a longer lifespan and require less maintenance. Solar panels are a key component of solar street lights. During the day, the panels absorb sunlight, convert it into electricity, and store it in batteries. At night, the battery electricity is automatically converted into light (via a light controller), which is then illuminated by LEDs.
