First Claim
Patent Images
1. A wall controller for controlling at least one lighting fixture in a lighting network and configured as a power over Ethernet (PoE) powered device (PD), the wall controller comprising:
- switch circuitry configured to receive lighting level input information indicative of a desired lighting level;
a PoE interface configured to facilitate Ethernet-based communications over an Ethernet cable and receive sourced power via the Ethernet cable from a power sourcing entity (PSE);
a power supply unit associated with the PoE interface and configured to provide supply power from the sourced power; and
a controller configured to;
receive the supply power from the power supply unit for operation;
receive the lighting level input information from the switch circuitry; and
send switch control information based on the lighting level input information via the PoE interface toward the at least one lighting fixture via the PoE interface to control an output level of a light source of the at least one lighting fixture.

Abstract
In a first embodiment, a lighting fixture is configured as a power over Ethernet (PoE) powered device (PD), which is capable of facilitating Ethernet-based communications with and receiving power from a PoE device, such as a PoE switch, over a single cable. In a second embodiment, a lighting fixture is configured as a PoE power source equipment (PSE) device, which is capable of facilitating Ethernet-based communications with and supplying power to one or more control elements.
