Illumination techniques and devices
First Claim
1. A lighting system comprising:
- a first luminaire including a first light source configured to emit white light from a front facing surface of the lighting system wherein the resultant white light simulates at least one of an intensity, color and/or color temperature of sunlight;
a second luminaire including a second light source configured to emit colored light from a rear facing surface of the lighting system and producing a wash of emitted colored light on a surface to which the lighting system is mounted and wherein the resultant mixed colored light simulates at least one of an intensity, color, and/or temperature of the sky; and
lighting controller circuitry operatively coupled with the first light source and the second light source wherein the light emitted by the first luminaire and by the second luminaire is tuned to adjust at least one of an intensity, color and/or color temperature to simulate changes in the sunlight and the sky over a period of daytime.

Abstract
Illumination techniques and related devices are disclosed. In some cases, a lighting device configured as described herein may include a front luminaire configured to emit white light and a back luminaire configured to emit colored light. The lighting device can be operatively coupled with controller circuitry programmed or otherwise configured, for example, with one or more algorithms which control the light output of the front and/or back luminaire so as to provide tunability. In some cases, device output may be controlled so as to: (1) simulate lighting conditions/patterns corresponding to the daytime/nighttime on Earth; (2) support/alter physiological processes; and/or (3) provide a specific ambient lighting for a given space. In some instances, a system of multiple such lighting devices can be provided, and in some cases, communication between constituent lighting devices may be provided. In some instances, the lighting device may be mountable as a sconce or other lighting fixture.
