Abstract: A method for identifying, recording, encoding, or reproducing electromagnetic radiation employs machine learning models. For example, each of multiple training illuminations may be measured using first and second types of systems. The first type of system may be a low-cost system that includes light sensors and measures an array of readings; the second type of system may be a precision spectrometer that measures the spectral power distribution. A trained machine learning model may predict the spectral power distribution of illumination from the array associated with the first type of system and may predict the representation of illumination understood by a spectrally tunable luminaire. The array of readings associated with the first type of system may be used to identify, record, encode, or reproduce electromagnetic radiation.

Abstract: A multi-track illumination content editing system allows creation or alteration of content using multiple input tracks representing illumination or other electromagnetic emissions and auxiliary content representing presentations other than electronic emissions, e.g., images, audio, or video. The editing system may particularly perform mixed media editing that manipulates both illumination and auxiliary content so that output illumination or auxiliary tracks depend on both illumination and auxiliary input tracks.

Abstract: A lighting system includes multiple light sources and a control system. The light sources have different emission spectra, and the control system may be configured to process a file containing lighting data to select respective intensities for emissions from the light sources. The file may particularly represent a light track that is synchronized with video content, to create a time-varying lighting ambiance for a movie or a video game.

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: 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 merit function of 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 value of the merit function thus determined can be used to identify a synthesized illumination, for example, the synthesized illumination that provides a smallest value. A luminaire system can implement such a process in a luminaire or in a control system for luminaires.

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: A luminaire produces lighting as a series of frames of constant spectral content includes sensors and an interpreter for executing scripts that describe the spectral contents of respective frames. The scripts may include spectral data and executable code for altering the spectral data and depend on sensor data. In particular, a frame descriptor may include data for a frame, a repeat count indicating a number of frames, and an identifier for a subroutine that uses sensor data. One or more luminaires can be network connected to one or more computers running applications providing user interfaces for script generation. A standardized interface can control communications with the luminaires and convey sensor data.

Abstract: An illumination content editing system and an illumination content translator allow creation or alteration of illumination content and translation of illumination content so that illumination represented by the illumination content can be played in disparate illumination systems. Translation may particularly employ characteristics of the disparate illumination systems, and the characterizations may be determined using automated or manual processes.

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.
