Abstract: A lighting system configured for daylight emulation. The system includes a plurality of light sources for generating a daylight-emulating output light spectrum and a ventilation element for generating a simulated breeze to artificially emulate conditions in an outside environment of an enclosed structure in which the lighting system is disposed. The system also includes a controller for dynamically controlling at least one of the intensity, directionality and color temperature to emulate sun position for at least one of a geography and time of day.

Abstract: An optical beam scanner includes a first optical beam steering device having a first surface thereon, which is configured to redirect a first optical beam incident thereon through reflection, refraction and/or diffraction of the first optical beam, and a second optical beam steering device having a second surface thereon, which is configured to reflect the redirected first optical beam incident thereon at a scanning target when both first and second surfaces are rotating about respective first and second axes of the first and second optical beam steering devices and the redirected first optical beam is tracing an uninterrupted loop on the second surface. The first optical beam steering device may be configured as a first monogon, a first prism, or a first grating, and the second optical beam steering device may be configured as a second monogon. The first and second axes may be collinear.

Abstract: An optical beam steering device includes an at least partially optically transparent container having a polygonal reflector therein that is at least partially surrounded within the container by an optically transparent liquid. The polygonal reflector may be configured to have a center of mass, which is equivalent to its geometric center. In addition, the polygonal reflector may be configured so that a difference between an effective density of the polygonal reflector and a density of the optically transparent liquid is preferably less than about 2.1 grams per cubic centimeter. More preferably, the polygonal reflector and the optically transparent liquid may be collectively configured to be neutrally buoyant relative to each other within the container.

Abstract: An optical beam steering device can include a first electrically conductive fluid having an optically reflective surface thereon, and this first electrically conductive fluid may include a material that deforms in response to application of a first magnetic field and/or first electric field thereto. This first electrically conductive fluid may be an optically reflective material. The optically reflective surface may at least partially cover a non-fluid substrate that maintains its shape in response to the application of the first magnetic field and/or first electric field. A sealed package may be provided, which includes the optical beam steering device, and the first electrically conductive fluid, the non-fluid substrate and an ambient within the package may be collectively configured to yield a substantially neutrally buoyant condition therein.

Abstract: A natural light emulation system employs at least one lighting assembly for providing light simulating natural light. The lighting assembly has several light engines around a light well. The light engines each have a number of light sources capable of providing light to the light well. A controller calculates lighting parameters for natural light received at a location on earth, at a day of the year and time of day. The controller then selectively operates light sources to provide light of a calculated spectrum and intensity that simulates light of a given direction. A master controller may be employed to control a group of lighting assemblies, or to control several different groups which may be simulating natural light relating to different locations, time of day or day of the year parameters.
