Design and implementation of LED intelligent lighting system based on the technology of PoE

With the development of Internet of Things, technology of Power over Ethernet can take enough electricity to LED lighting system. Depending on the sensed information of the current brightness and the number of persons in a room, the system can automatically identify and apply a predefined brightness. Therefore, it overcomes the disadvantages of traditional light control systems, for example, inefficient management, uncomfortable, waste of energy and security. At the same time system can transfer DC power and data through Ethernet, reduce the power adapter failure which caused by data network failure and promote the application of the low power network equipment. In addition, it has a wireless control function and makes the system more humanized.
