Devices and methods for lighting reflector to visibly emphasize different lighting characteristics of multiple light groups

A lighting device, comprising:

• a reflector defining a reflective cavity having an interior surface and an opening;
• a first group of controllable light emitters positioned along a first edge of the opening of the reflective cavity to emit light away from the opening of the reflective cavity through the reflective cavity toward a first portion of the interior surface;
• a second group of controllable light emitters positioned along a second edge of the opening of the reflective cavity separate from the first portion to emit light away from the opening of the reflective cavity through the reflective cavity toward a second portion of the interior surface different from the first portion;
• a controller coupled to the first and second groups of light emitters, the controller being configured to:
• control the first group of emitters to emit light having a first value of a spectral characteristic of emitted light reflected from the first portion of the interior surface and visible through the opening of the reflective cavity;
• and
• control the second group of emitters to emit light having a second value of the spectral characteristic of emitted light reflected from the second portion of the interior surface and visible through the opening of the reflective cavity, the second value being different from the first value, such that the reflected light from the first group is visibly distinguishable to an observer from the reflected light from the second group.

A method comprising:

• emitting light from a first group of controllable light emitters positioned along a first edge of an opening of a reflective cavity of a reflector through the reflective cavity, an interior surface of the reflective cavity comprising at least one first feature adapted to reflect light in a first manner, and at least one second feature adapted to reflect light in a second manner different from the first manner, the first group emitting light away from the opening of the reflective cavity toward the at least one first feature;
• emitting light from a second group of controllable light emitters positioned along a second edge of the opening of the reflective cavity separate from the first portion through the reflective cavity away from the opening of the reflective cavity toward the at least one second feature;
• controlling the first group of emitters to emit light having a first value of a characteristic of emitted light reflected from the at least one first feature and visible through an opening of the reflective cavity;
• and
• controlling the second group of emitters to emit light having a second value of the characteristic of emitted light reflected from the at least one second feature and visible through the opening of the reflective cavity, the second value being different from the first value.

• control the second group of emitters to emit light having a second value of intensity reflected from the second portion of the interior surface and visible through the opening of the reflective cavity, the second value being different from the first value, such that the reflected light from the first group is visibly distinguishable to an observer from the reflected light from the second group;
• and
• adjust the intensity of the light emitted by at least one of the first and second groups over time while maintaining an overall level of intensity of light emitted by the lighting device.

A lighting device, comprising:

• a reflector defining a reflective cavity having an opening and an interior surface of the reflective cavity comprising:
• at least one first feature adapted to reflect light, received from a first direction, out through the opening;
• and
• at least one second feature adapted to reflect light, received from a second direction different from the first direction, out through the opening;
• a first group of controllable light emitters positioned along a first portion of a periphery of the opening of the reflective cavity to emit light away from the opening of the reflective cavity and from the first direction through the reflective cavity toward the at least one first feature;
• a second group of controllable light emitters positioned along a second portion of the periphery of the opening of the reflective cavity separate from the first portion to emit light away from the opening of the reflective cavity and from the second direction through the reflective cavity toward the at least one second feature;
• a controller coupled to the first and second groups of light emitters, the controller being configured to:
• in a first state, control the first group of emitters to emit light having a first value of a characteristic of emitted light reflected from the at least one first feature and visible through the opening of the reflective cavity to optically emphasize the at least one first feature;
• and
• in a second state, control the second group of emitters to emit light having a second value of the characteristic of emitted light reflected from the at least one second feature and visible through the opening of the reflective cavity, the second value being different from the first value, to optically emphasize the at least one second feature instead of the at least one first feature.
