Abstract
Lighting control systems including a driver circuit. One example lighting control system includes an input node, a first light source connected to the input node and configured to generate a first light, and a second light source connected to the input node and configured to generate a second light. The lighting control system also includes a driver circuit connected to the input node. The driver circuit is configured to receive a first signal indicating a driving state of the lighting control system, receive a second signal indicating a magnitude value of an output signal, and generate the output signal based on the first signal and the second signal. The driver circuit is configured to provide the output signal to the input node to control the first light source and the second light source.
Claims17
A lighting control system comprising:
- an input node;
- a first light source connected to the input node and configured to generate a first light;
- a second light source connected to the input node and configured to generate a second light;
- a driver circuit connected to the input node and configured to:
- receive a first signal indicating a driving state of the lighting control system,
- receive a second signal indicating a magnitude value of an output signal,
- generate the output signal based on the first signal and the second signal, and
- provide the output signal to the input node to control the first light source and the second light source;
- and
- a switching device configured to control whether power is provided to the first light source or the second light source based on an amplitude of the output signal.
A method for controlling a plurality of light sources including a first light source connected to an input node and a second light source connected to the input node, the method comprising:
- receiving, with a driver circuit, a first signal indicating a driving state of the driver circuit;
- receiving, with the driver circuit, a second signal indicating a magnitude value of an output signal;
- generating, with the driver circuit, the output signal based on the first signal and the second signal;
- providing, with the driver circuit, the output signal to the input node to control the first light source and the second light source;
- and
- controlling, with a switching device, whether power is provided to the first light source or the second light source based on an amplitude of the output signal.
A lighting control system comprising:
- an input node;
- a first light source connected to the input node and configured to generate a first colored light;
- a second light source connected to the input node and configured to generate a colored second light different from the first colored light;
- a multiplexer configured to generate a first signal based on a driving state of the lighting control system;
- a driver circuit connected to the multiplexer and to the input node and configured to:
- receive, from the multiplexer, the first signal,
- receive a second signal indicating a magnitude value of an output signal,
- generate the output signal based on the first signal and the second signal, and
- provide the output signal to the input node to control the first light source and the second light source;
- and
- a switching device configured to control whether power is provided to the first light source or the second light source based on an amplitude of the output signal.
