Abstract

A lighting fixture incorporates a peripheral light emission feature, such as a peripheral waveguide and/or a peripheral reflector region. A peripheral light emission feature may at least partially surround a non-peripheral feature that may include a light-transmissive panel. At least one first light source may illuminate a peripheral light emission feature, and at least one second light source may illuminate a light transmissive panel. Control circuitry is configured to selectively adjust intensity and/or color temperature of the light sources to cause aggregate emissions of the lighting fixture (or a lighting system with multiple lighting fixtures) to dynamically change over time (e.g., with different intensities and color temperature), so as resemble a skylight or window. A viewer may thereby perceive at least portions of a space as being naturally illuminated.
