Patent number: 9055622Abstract: Disclosed examples of optical systems having a plurality of light sources with each source having a different spectral outputs may be calibrated by measuring a spectral characteristic of the combined light with two measurements, e.g., one from a colorimeter and one from a sensor included in the system. Accordingly, one can determine a transform function in response to the two measures that models a feedback response of the optical system for each of a plurality of the inputs that would cause the optical system to generate radiant energy within a predetermined range of a spectrum. In order to calibrate the optical system, the transform function is programmed in the optical system to enable the optical system to transform an input to the optical system to a plurality of unique control signals each for controlling a respective light source of the plurality of light sources.Type: GrantFiled: January 29, 2013Date of Patent: June 9, 2015Assignee: ABL IP HOLDING LLCInventors: Matthew H. Aldrich, Michael E. Garbus, Jr.

Patent number: 8294074Abstract: A solid state lighting system controls overall light output level in a step-wise manner by discretely controlling the ON/OFF state of its light emitters. Solid state emitters that are ON at a given time are set and kept at a level intended to produce a desired output characteristic, e.g. at a level to produce a described color of light. The system utilizes optical processing of the generated light, for example by diffuse reflection in an optical integrating cavity, sufficient to convert the point source output(s) from the emitting elements into a uniform virtual source output. The virtual source output appears uniform regardless of how many emitters are ON or OFF, and only the perceptible intensity of the light output changes with the number of emitters that the system has ON.Type: GrantFiled: May 12, 2009Date of Patent: October 23, 2012Assignee: ABL IP Holding LLCInventors: Steve S. Lyons, Michael E. Garbus, Jr., Matthew H. Aldrich

Publication number: 20090034249Abstract: Disclosed examples of lighting systems having at least three light sources of different colors may be controlled by validating input settings representing chromaticity and/or intensity of desired light to be generated by determining if the respective lighting system is capable of generating the desired light. This may involve comparing the chromaticity and/or intensity to a three-dimensional gamut representing chromaticity and associated intensities that the lighting system is capable of generating. The top contour of the gamut represents the maximum intensities for every chromaticity which the lighting system is capable of generating. Specifically the top contour is defined by points representing the maximum attainable intensities that each light source is capable of generating and the maximum intensity attainable by the lighting system.Type: ApplicationFiled: October 1, 2008Publication date: February 5, 2009Applicant: RENAISSANCE LIGHTING, INC.Inventor: Michael E.

Publication number: 20080228508Abstract: Techniques are disclosed to monitor the time of operation of a solid state lighting system, e.g. for warranty purposes. Examples are disclosed that measure time of system connection to power and/or time of light output from the solid state emitter(s) of the system. A service under the warranty is provided if operation time does not exceed the warranty eligibility criteria, e.g. maximum limit(s). The service provided under the warranty may be pro-rated based on the time of operation.Type: ApplicationFiled: March 13, 2007Publication date: September 18, 2008Inventors: Steve S. Lyons, Michael E.
