14 Claims

1. A lighting fixture comprising:

a light-transmissive panel;

at least one waveguide positioned along a perimeter of the light-transmissive panel, wherein the at least one waveguide comprises a face that is transversely oriented relative to the light-transmissive panel and extends from the light-transmissive panel to a waveguide distal edge spaced from the light-transmissive panel;

at least one first light source configured to illuminate the light-transmissive panel;

at least one second light source configured to illuminate the at least one waveguide; and

control circuitry configured to selectively adjust, for one or more of the at least one first light source and the at least one second light source, at least one of intensity and color temperature to cause aggregate emissions of the lighting fixture to dynamically change over time;

wherein the lighting fixture is configured to be suspended by one or more elongated suspension elements from, and spatially segregated from, a ceiling structure.
