Abstract: A method of utilizing a light replication luminaire to match the spectral characteristics of light that is output from the luminaire to the spectral characteristics of a target light spectrum is provided. In one example, the method permits the user to assign a weight to one or more characteristics of the target light spectrum to be replicated. A best approximation of the target light spectrum is then determined, taking into account the weight assigned to each characteristic. In another example, the target light spectrum is provided to the luminaire by the user through the specification of various characteristics of the target light spectrum.

Abstract: Systems and methods permit use of efficient solid state emitters for broad spectrum continuous spectrum lighting defined by illumination data. The illumination data, which can be sold as a commercial product, can be recorded or authored and include spectral, temporal, and spatial information. A lighting fixture can use information such as the illumination data, emitter age, temperature, and calibration data to calculate drive levels as needed to control intensities of individual emitters and thereby produce desired patterns of spectral content and time variation.

Abstract: A system may include: a light valve exposed to incident light from an external light source. The light valve may independently modulate multiple wavelength bands of the incident light that are transmitted through the light valve and into an environment that the system illuminates. A control system can operate the light valve to control a spectral distribution of light transmitted through the light valve.

Abstract: Illumination of an environment can be selected based on target colors that the illumination would provide for specific samples. One process for synthesizing the illumination includes repeatedly selecting settings for separate light sources in a luminaire system and determining a difference between the target colors of the samples and apparent colors of the samples under illumination that the luminaire system would produce with the settings selected. The differences thus determined can be used to identify a synthesized illumination, for example, the synthesized illumination that provides a smallest difference. A luminaire system can implement such a process in a luminaire or in a control system for luminaires.

Abstract: Systems and methods permit use of efficient solid state emitters for broad spectrum continuous spectrum lighting defined by illumination data. The illumination data, which can be sold as a commercial product, can be recorded or authored and include spectral, temporal, and spatial information. Intensities of individual emitters such as LEDs can be controlled through a combination of pulse width modulation (PWM) and amplitude modulation (AM) of drive currents. The combination of PWM and AM permits fine tuning of the spectrum of emissions and creation of free space optical data channels.

Abstract: A lighting system includes multiple light sources, a sensing unit, and a control system. The light sources have different emission spectra, and the sensing unit is configured to measure a spectral content of light. The control system may be configured to use measurements from the sensing unit to select respective intensities for emissions from the light sources and then independently control the light sources to emit the respective intensities. In particular, the control system can select and render a spectral distribution selected based on the light reflected from objects that are being illuminated or render a spectral distribution to supplement light from other light sources and achieve a lighting objective.

Abstract: Embodiments of the present invention relate to systems and methods for creating, distributing and playing illumination data files. The illumination data files, created using luminaire development systems are uploaded to a luminaire management system, where they are further processed and packaged for sale or license within a luminaire marketplace. Consumers and enterprises using luminaires may establish accounts with the luminaire management system and marketplace to access illumination data files for playback on individual or multiple luminaires. Consumers and enterprises may also create play lists and uniquely configure the luminaires to display various lighting effects based on user preferences, environmental factors or energy efficient settings.

Abstract: A linear lamp is provided having one or more light emitting elements provided therein. The light emitting elements are directed to emit light in a direction different from the primary direction of the illumination of the lamp. The light emitting elements may be supported by a supporting optical element. The supporting optical element may permit the transmission of light therethrough. The supporting optical element may be an integral window upon which the light emitting elements are disposed.

Abstract: A light emitting device is produced by depositing a layer of wavelength converting material over the light emitting device, testing the device to determine the wavelength spectrum produced and correcting the wavelength converting member to produce the desired wavelength spectrum. The wavelength converting member may be corrected by reducing or increasing the amount of wavelength converting material. In one embodiment, the amount of wavelength converting material in the wavelength converting member is reduced, e.g., through laser ablation or etching, to produce the desired wavelength spectrum.
