  • Systems, methods, and devices for influencing spectral content of a light output
    Patent number: 11849519
    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.
    Type: Grant
    Filed: January 25, 2022
    Date of Patent: December 19, 2023
    Assignee: Electronic Theatre Controls, Inc.
    Inventors: William R. Florac, Evan Gnam, Wendy Luedtke, James Uphoff
