Abstract

The present invention relates to a system, method, and apparatus for powering intelligent lighting networks. The power for the intelligent lighting network is supplied by Power-over-Ethernet (PoE) switches and/or Mid-Spans, which are conditioned by a powered device to distribute power tuned specifically for each, at least one light emitting diode (LED) fixture. The Power-over-Ethernet switch and/or Mid-Span with associated router and wireless access point can be used to communicate with, and power a sensor network that collects data relevant to the intelligent lighting network. Optionally, the Power-over-Ethernet switch and/or Mid-Span can be used to communicate with, and power a network of sensors that collects data relevant to the space the intelligent lighting network is operating in, or can be used to communicate with and power a network of AC wall plugs that can be turned on and off, and various switches, relays, and PLCs, RFID systems, USB hubs, etc.
