Abstract
A system for providing power over Ethernet illuminated signage is provided. The system includes receiving lighting instructions via an Ethernet compatible communications protocol, translating those instructions to a lower bandwidth, slower protocol while passing through DC power. Illumination fixtures are powered by the passed-through power and operated in accordance with the translated instructions.
Claims19
A PoE illumination system,
- a PoE input;
- a power and data separator in electronic communication with the PoE input, the power and data separator having a power output and a bi-directional data output;
- an Ethernet transceiver in electronic communication with the bi-directional output of the power and data separator;
- a communications interface module in electronic communication with the Ethernet transceiver,
- a digital lighting controller including a digital transceiver in communication with the communications interface module, the lighting controller having a data output;
- a power distribution module in electronic communication with the power output of the power and data separator, and
- a lighting power and control output having a plurality of conductor pairs, a first pair in electronic communication connected to receive an output of the power distribution module, and a second pair connected to receive an output of the digital lighting controller.
4 more elements
A method of supplying power and data to a plurality of lighting fixtures, comprising:
- receiving a first set of digital lighting control instructions encoded according to an Ethernet communication standard and DC power at a first voltage over an PoE link;
- providing the DC power at a first voltage to a plurality of lighting fixtures;
- translating the first set of digital lighting instructions to a second set of digital lighting instructions encoded under a second digital communications standard, the second set of lighting instructions including instructions for the plurality of lighting fixtures;
- providing the second set of instructions to the plurality of lighting fixtures.
1 more element
A method of operating a lighting fixture, comprising:
- at an interface converter and distribution module:
- receiving a first set of digital lighting control instructions encoded according to an Ethernet communication standard and DC power;
- providing the DC power to an Ethernet output;
- translating the first set of digital lighting instructions to a second set of digital lighting instructions encoded under the DALI standard;
- providing the second set of digital lighting instructions to the same Ethernet output.
