  • Patent number: 11778707
    Abstract: Disclosed herein are methods for controlling light fixtures comprising unique color light sources with independently controllable luminous flux, comprising controlling a luminous flux of each of the light sources, wherein a spectral distribution of light emitted from the light sources upon being controlled according to settings within a plurality of setting is different between settings, and a color of light emitted from the light sources is similar or identical between settings. The methods may improve color rendering where a certain color of emitted light is required, e.g., where a certain prop or costume is better illuminated with one setting compared to another setting, drawing attention to certain objects in a scene, e.g., by choosing a setting which makes a certain object stand out, and/or providing an intriguing optical effect, e.g., by shifting between settings, which makes certain objects appear to change color while others appear to keep same color.
