[Abstract]:With the advent of the Internet era, network technology is booming, the level of network in various regions has been improved, Ethernet has been extended to every corner of the world. People began to try a network to solve both communication problems and power supply problems, so Ethernet power supply has gradually become a new direction in the field of power supply. However, the problem of energy shortage in the world is becoming increasingly prominent. With the improvement of people's quality of life, the demand for energy saving and comfort of indoor lighting system is also becoming higher and higher.

In summary, the solar energy LED intelligent lighting system based on PoE technology is an innovative application of PoE technology in low-voltage DC intelligent lighting, which greatly reduces the cost of network construction. The 48V low-voltage DC power supply with full use of solar energy has high safety and reliability, and realizes the green idea of maximizing solar power supply by solar energy. A natural light indoor illumination attenuation model is set up. The complex arrangement method of indoor illumination acquisition device is avoided, which provides a new idea for improving indoor light environment, saving resources and protecting environment.
