Patent number: 7781713Abstract: One embodiment of the present invention provides a system for calibrating a lighting control system. The lighting control system is a daylight-harvesting system that controls the output of the lighting system based on available daylight and/or other light sources to reduce energy usage while providing lighting for an area. The lighting system includes multi-level lighting capabilities for one or more light sources. First, the system measures the light levels for the area when the lighting system: is turned on at a high energy-level; is turned on at an intermediate energy-level; and is turned off. The system determines from these measured light levels the light output of the lighting system in the different states. Then, during operation, the system measures a present light level for the area. The system then adjusts the light output of the lighting system for the area based on a lighting control parameter (e.Type: GrantFiled: February 8, 2007Date of Patent: August 24, 2010Assignee: The Regents of the University of CaliforniaInventors: Konstantinos Papamichael, Keith Graeber, Erik Page, Michael Siminovitch

Patent number: 7683301Abstract: One embodiment of the present invention provides a system for preventing incorrect lighting changes in a daylight-harvesting system, which controls the output of a lighting system based on the presence of daylight and/or other light sources to reduce energy usage. During operation, the system measures a first light level using a first sensor. Next, the system measures a second light level for a different field-of-view using a second sensor. When the system detects through the first sensor a change in the first light level, the system determines from the second sensor whether the second light level has also changed. If the first sensor and the second sensor both detect a change (in the same direction) in the measured light levels, the system adjusts the light output of the lighting system to maintain target light levels for the area.Type: GrantFiled: February 8, 2007Date of Patent: March 23, 2010Assignee: The Regents of the University of CaliforniaInventors: Konstantinos Papamichael, Keith Graeber, Erik Page, Michael Siminovitch

Publication number: 20080005044Abstract: One embodiment of the present invention provides a system that uses power-line phase-cut signaling to change energy usage for one or more devices that share a common power signal. During operation, the system receives a request to change power usage. In response to the request, the system inserts a phase-cut notch into the common power signal. A device that is located downstream from the inserted phase-cut notch detects this notch in the common power signal, and in response triggers a power-state change. For instance, the device may trigger a reduced-power state when it detects a phase-cut notch.Type: ApplicationFiled: May 24, 2007Publication date: January 3, 2008Inventors: James Benya, Joel Snook, Erik Page, Michael Siminovitch, Konstantinos Papamichael, Don Aumann, Margaret Aumann

Publication number: 20070290621Abstract: A modular lighting system for lighting a work area is disclosed. The system includes a power supply with power outlets for powering LED fixtures. The power supply preferably operates at or below a fixed power output level, such as to illuminate the work area using less than 0.2 Watts per square foot of energy. The lighting system also includes an occupancy sensor and/or a light level sensor for controlling lighting levels in the work area in response to detection of a person, ambient light levels and/or a combination thereof. The lighting system can also include computer unit with a micro-processor and a memory unit for running software or firmware the executes lighting programs, stores light usage histories and/or provides system reports to a remote computer by a wireless means and/or over a computer network.Type: ApplicationFiled: May 10, 2007Publication date: December 20, 2007Inventors: Walter Clark, Douglas Joseph Bourne, Erik Page, Michael Siminovitch, Kevin Gauna

Patent number: 6217197Abstract: Disclosed herein is a reflector system for a lighting fixture having a illumination source surrounded by an envelope. The reflector system includes a first reflector surrounding the illumination source. The reflector system also includes a second reflector which is non-contiguous with the first reflector and which surrounds the illumination source. The illumination source creates light rays which are reflected by the first and second reflectors. The first reflector directs light rays toward the center line of the fixture. However, the reflected rays despite being so reflected do not substantially intersect the envelope. The reflected light rays from the second reflector being directed so that they diverge from the center line of the fixture avoiding intersection with the semi-transparent envelope.Type: GrantFiled: July 31, 1998Date of Patent: April 17, 2001Inventors: Michael J. Siminovitch, Erik Page, Carl T. Gould
