Abstract
A gateway controls a portion of lighting fixtures within a lighting system in response to a first digital signal and comprises a power input port to receive AC power, a power line filter to filter electrical noise from the received AC power, a power output port to output the filtered AC power to the portion of lighting fixtures, an input signal port to receive the first digital signal, an output signal port to pass the received first digital signal to a second gateway, a local controller, a first transceiver coupled to the input signal port to receive the first digital signal, and a second transceiver coupled to the power output port to couple the second digital signal to the power output port.
Claims25
A first gateway to control a portion of lighting fixtures within a lighting system, the first gateway installable within the lighting system to receive a first digital signal and control at least one lighting fixture of the portion of lighting fixtures in response to receipt of the first digital signal, the first gateway comprising:
- a power input port to receive AC power;
- a power line filter coupled to the power input port to filter electrical noise from the received AC power thereby producing filtered AC power when the first gateway is operating in the lighting system;
- a power output port to output the filtered AC power to the portion of lighting fixtures;
- an input signal port to receive the first digital signal;
- and
- an output signal port communicatively coupled to the input signal port to pass the received first digital signal to a second gateway, wherein the first gateway is configured to couple a second digital signal to the power output port in response to receiving the first digital signal to control the at least one lighting fixture of the portion of lighting fixtures,
- the first gateway further comprising:
- a local controller installed within the first gateway;
- a first transceiver coupled to the input signal port to receive the first digital signal;
- and
- a second transceiver coupled to the power output port to couple the second digital signal to the power output port.
A first gateway to control a portion of lighting fixtures within a lighting system, the first gateway installable within the lighting system to receive a first digital signal and control at least one lighting fixture of the portion of lighting fixtures in response to receipt of the first digital signal, the first gateway comprising:
- a power input port to receive AC power;
- a power line filter coupled to the power input port to filter electrical noise from the received AC power thereby producing filtered AC power when the first gateway is operating in the lighting system;
- a power output port to output the filtered AC power to the portion of lighting fixtures;
- an input signal port to receive the first digital signal;
- and
- an output signal port communicatively coupled to the input signal port to pass the received first digital signal to a second gateway, wherein the first gateway is configured to couple a second digital signal to the power output port in response to receiving the first digital signal to control the at least one lighting fixture of the portion of lighting fixtures,
- the first gateway further comprising:
- a local controller installed within the first gateway;
- memory communicatively coupled to the local controller;
- and
- a user interface integrated with the first gateway and communicatively coupled to the local controller, the user interface comprising at least one input to configure operation of the first gateway with the portion of lighting fixtures,
- wherein:
- the user interface is operable to initiate running of at least one program by the local controller;
- and
- the at least one program comprises a test of intensity control and color temperature control of the portion of lighting fixtures.
A first gateway to control a portion of lighting fixtures within a lighting system, the first gateway installable within the lighting system to receive a first digital signal and control at least one lighting fixture of the portion of lighting fixtures in response to receipt of the first digital signal, the first gateway comprising:
- a power input port to receive AC power;
- a power line filter coupled to the power input port to filter electrical noise from the received AC power thereby producing filtered AC power when the first gateway is operating in the lighting system;
- a power output port to output the filtered AC power to the portion of lighting fixtures;
- an input signal port to receive the first digital signal;
- and
- an output signal port communicatively coupled to the input signal port to pass the received first digital signal to a second gateway, wherein the first gateway is configured to couple a second digital signal to the power output port in response to receiving the first digital signal to control the at least one lighting fixture of the portion of lighting fixtures,
- the first gateway further comprising:
- a local controller installed within the first gateway;
- memory communicatively coupled to the local controller;
- and
- a user interface integrated with the first gateway and communicatively coupled to the local controller, the user interface comprising at least one input to configure operation of the first gateway with the portion of lighting fixtures,
- wherein:
- the user interface is operable to initiate running of at least one program by the local controller;
- and
- the at least one program comprises a test of connectivity of each lighting fixture of the portion of lighting fixtures to the first gateway.
