20090127431ILLUMINATION SYSTEM CALIBRATION AND OPERATION HAVING A CALIBRATION MATRIX CALCULATION BASED ON A SHIFT IN COLOR SPACE (AS AMENDED) - A method for calibrating an illumination system is disclosed herein. The illumination system comprises at least one light emitter and at least one color sensor. The method comprises emitting a first wavelength of light from the a light emitter and measuring the color of light emitted by the light emitter using the color sensors. A second wavelength of light is emitted from the a light emitter and the color of light emitted by the light emitter is measured using the color sensors. The shift in color space based on the measurements is calculated. At least one calibration matrix based on the shift in colors space is calculated.05-21-2009
20110073878LED ARRAY PACKAGE COVERED WITH A HIGHLY THERMAL CONDUCTIVE PLATE - A light source includes a substrate, a light emitting diode on the substrate, and a phosphor layer over the light emitting diode. A plate is on the phosphor layer. An attachment member is coupled to the plate and is configured to conduct heat away from the plate.03-31-2011

20110045614Method and Apparatus for Providing LED Package with Controlled Color Temperature - An optical device capable of illuminating visual light with adjusting color temperature after fabrication is disclosed. The optical device includes a solid state light emitter and a phosphor layer, which is formed over the solid state light emitter. The solid state light emitter, which can be a light emitter diode (“LED”), converts electrical energy to blue light. The phosphor layer subsequently converts first light with a first wavelength to second light with a second wavelength. In one example, the first light is blue light while the second light is white light. A portion of the phosphor layer is adjusted after the phosphor layer is formed for adjusting color of the white light in accordance with color quality of the light detected by a light detector.02-24-2011

20080251699METHOD AND SYSTEM FOR WAVELENGTH-DEPENDENT IMAGING AND DETECTION USING A HYBRID FILTER - Apparatus and methods for wavelength-dependent detection are provided. A detector includes a hybrid filter having unpatterned and patterned filter layers and at least one light-detecting sensor that detects light in first and second wavelength bands from the patterned filter layer of the hybrid filter. The unpatterned filter layer passes light in two nonoverlapping wavelength bands relative to light in wavelength bands between or among the nonoverlapping wavelength bands. The patterned filter layer includes first and second regions configured respectively to pass light in the first and second wavelength bands of the nonoverlapping wavelength bands passed by the unpatterned filter layer.10-16-2008
