Abstract
A lighting control system for controlling a cumulative light emitted by a lighting fixture having a plurality of LED light sources may comprise a plurality of LED drivers adapted to be coupled to a respective one of the LED light sources and configured to control an intensity of the respective LED light source, and a controller configured to transmit a single digital message for controlling the cumulative light emitted by the lighting fixture. Each of the plurality of LED drivers is configured to adjust the intensity of the respective LED light source to a preset intensity in response to the single digital message transmitted by the controller.
Claims20
A lighting control system for controlling a cumulative light emitted by a lighting fixture having a plurality of light-emitting diode (LED) light sources, the lighting control system comprising:
- at least one LED driver located within the lighting fixture;
- a control module located within the lighting fixture and coupled to the at least one LED driver, and configured to control the at least one LED driver to control the cumulative light emitted by the plurality of LED light sources of the lighting fixture;
- and
- a controller located external to the lighting fixture and configured to transmit at least one digital message to the control module for controlling the cumulative light emitted by the plurality of LED light sources of the lighting fixture;
- wherein the control module is further configured to receive the at least one digital message from the system controller and to control the at least one LED driver to adjust respective intensities of the plurality of LED light sources to respective preset intensities in response to the at least one digital message transmitted by the controller.
A lighting fixture comprising:
- a plurality of light-emitting diode (LED) light sources configured to generate a cumulative light emitted by the lighting fixture;
- at least one LED driver;
- and
- a control module configured to control the at least one LED driver to control the cumulative light emitted by the lighting fixture, the control module further configured to:
- receive at least one digital message for controlling the cumulative light emitted by the plurality of LED light sources;
- and
- control the at least one LED driver to adjust respective intensities of the plurality of LED light sources to respective preset intensities in response to the at least one digital message.
A control module configured to be installed in a lighting fixture and for controlling a cumulative light emitted by the lighting fixture, the lighting fixture configured to include a plurality of LED light sources and a plurality of LED drivers, the plurality of LED drivers configured to be coupled to a respective one of the plurality of LED light sources and configured to control an intensity of the respective one of the plurality of LED light sources, the control module comprising:
- a communication circuit configured to receive a digital message;
- a memory configured to store a light engine defining preset intensities for the LED light sources;
- and
- a control circuit configured to use the light engine to control the plurality of LED drivers of the lighting fixture to adjust respective intensities of the plurality of LED light sources of the lighting fixture to respective preset intensities to control the cumulative light emitted by the lighting fixture in response to the digital message received via the communication circuit.
