Abstract: A method of light source classification includes determining a plurality of color regions in the CIE 1976 chromaticity diagram according to desired classification criteria. The plurality of color regions of the CIE 1976 chromaticity diagram are converted into a plurality of color classification regions defined by color coordinates of the CIE 1931 chromaticity diagram. The light source is classified into one of the plurality of color classification regions. This classification method may allow for precise classification based on actual color differences, while providing light sources having color uniformity in the same classification region.

Abstract: In the color imaging system, multiple rendering devices are provided at different nodes along a network. Each rendering device has a color measurement instrument for calibrating the color presented by the rendering device. A rendering device may represent a color display in which a member surrounds the outer periphery of the screen of the display and a color measuring instrument is coupled to the first member. The color measuring instrument includes a sensor spaced from the screen at an angle with respect to the screen for receiving light from an area of the screen. A rendering device may be a printer in which the measuring of color samples on a sheet rendered by the printer is provided by a sensor coupled to a transport mechanism which moves the sensor and sheet relative to each other, where the sensor provides light from the sample to a spectrograph. The color measuring instruments provide for non-contact measurements of color samples either displayed on a color display, or printed on a sheet, and are self-calibrating by the use of calibration references in the instrument.

Abstract: A luminous intensity test device includes an optical frequency converter, a display, and a processor. The optical frequency converter selectively converts at least a portion of light emitted by a light source into a digital signal. The display displays a color selection interface. The processor processes the digital signal and obtains the luminous intensity. When a tester inputs a color parameter into the color selection interface via an input device, the optical frequency converter converts a kind of light to the digital signal and then the processor processes the digital signal to obtain a luminous intensity and display the luminous intensity on the display.

Abstract: System(s), apparatus(es), and method(s) are provided for control of quality of light emitted from a group of solid-state light (SSL) sources that are part of an illumination fixture. The control is based at least in part on regulation of the spectral power distribution (SPD) of the light to match a SPD of a reference light source. A spectroscopic analyzer collects electromagnetic (EM) radiation emitted from the group of SSL sources and EM radiation substantially emitted from the reference light source. A first controller analyzes spectroscopic data related to SPDs of the group of SSL sources and the reference light source and, based on the analysis issues a configuration of the group of SSL sources. Implementation of the configuration causes the group of SSL sources to emit EM radiation with a SPD that nearly matches the SPD of the EM radiation substantially emitted from the reference light source.

Abstract: Proposed is a light sensor (1), comprising at least one wavelength selective photo-detector (10), a lens (20) and an aperture (30).The wavelength selective photo-detector allows detecting light within a predefined wavelength range falling on the sensor. The lens project light on the photo-detector and the aperture defines a field of view of the light sensor. The photo-detector (10), the lens (20), and the aperture (30) are arranged in a telecentric configuration. Advantageously, this allows light to impinge on the wavelength selective photo-detector within a predefined range of angles irrespective of the direction of the light incident on the aperture, thus removing the angle dependent response of the wavelength selective photo-detector.
