Power over Ethernet lighting system

摘要

A system for controlling a plurality of LED lighting fixtures includes a Power over Ethernet (PoE) LED driver coupleable to a PoE switch via a first power and communication link. The PoE LED driver includes a microcontroller for receiving first power and control signals from the PoE switch and for controlling a first LED driver chip to operate an LED lighting fixture in response thereto. An LED slave controller is connected to the PoE LED driver via a second power and communication link. The LED slave controller includes a second LED driver chip for receiving second power and control signals from the microcontroller to operate an LED lighting fixture in response. The first power and control signals are different from the second power and control signals. The first power and communication link is a CAT5/CAT6 cable. The second power and communication link is a CAT5/CAT6 or other cable type.
