Abstract
A method for control of a light fixture, the method including energizing the light fixture to produce a first light output with a first chromaticity and a first spectral power distribution, receiving a user input representative of a desired adjustment of a lighting effect, generating a target spectrum based on the user input, and energizing the light fixture to produce a second light output with the first chromaticity and a second spectral power distribution. The second power distribution approximates the target spectrum.
Claims20
A method for control of a light fixture, the method comprising:
- energizing the light fixture to produce a first light output with a first chromaticity and a first spectral power distribution;
- receiving a user input representative of a desired adjustment of a lighting effect;
- generating a target spectrum based on the user input;
- and
- energizing the light fixture to produce a second light output with the first chromaticity and a second spectral power distribution, the second power distribution approximates the target spectrum.
A lighting control system comprising:
- one or more light fixtures;
- one or more driver circuits configured to provide drive signals to the one or more light fixtures;
- a user interface configured to receive an input related to a light output of the one or more light fixtures, the input being representative of an adjustment of a lighting effect;
- and
- a controller connected to the one or more driving circuits and the user interface, the controller including a processor and a memory, the controller configured to:
- energize the one or more light fixtures to produce a first light output with a first chromaticity and a first spectral power distribution,
- receive the input representative of the adjustment of the lighting effect,
- generate a target spectrum based on the input, and
- energize the one or more light fixtures to produce a second light output with the first chromaticity and a second spectral power distribution, the second power distribution approximates the target spectrum.
A controller for controlling a light output of a light fixture, the controller including a non-transitory computer readable medium and a processor, the controller including computer executable instructions stored in the computer readable medium for controlling operation of the controller to:
- energize the light fixture to produce a first light output with a first chromaticity and a first spectral power distribution;
- receive an input representative of an adjustment of a lighting effect;
- generate a target spectrum based on the user input;
- and
- energize the light fixture to produce a second light output with the first chromaticity and a second spectral power distribution, the second power distribution approximates the target spectrum.
