Patent number: 8222584Abstract: A light fixture, using one or more solid state light emitting elements utilizes a diffusely reflect chamber to provide a virtual source of uniform output light, at an aperture or at a downstream optical processing element of the system. Systems disclosed herein also include a detector, which detects electromagnetic energy from the area intended to be illuminated by the system, of a wavelength absent from a spectrum of the combined light system output. A system controller is responsive to the signal from the detector. The controller typically may control one or more aspects of operation of the solid state light emitter(s), such as system ON-OFF state or system output intensity or color. Examples are also discussed that use the detection signal for other purposes, e.g. to capture data that may be carried on electromagnetic energy of the wavelength sensed by the detector.Type: GrantFiled: April 5, 2011Date of Patent: July 17, 2012Assignee: ABL IP Holding LLCInventors: Jack C. Rains, Jr., Don F. May, David P. Ramer

Patent number: 7148470Abstract: A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination of light) uses an optical integrating cavity to combine energy of different wavelengths from different sources. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the cavity. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture. A variety of different elements may optically process the combined light output, such a deflector, a variable iris, a lens, a variable focusing lens system, a collimator, a holographic diffuser and combinations thereof. Such systems are useful in various luminous applications as well as various illumination applications.Type: GrantFiled: December 6, 2005Date of Patent: December 12, 2006Assignee: Advanced Optical Technologies, LLCInventors: Jack C.
