  • Patent number: 11956868
    Abstract: A system for obtaining a multispectral image of a scene includes a first light source, a second light source, at least one imaging sensor, and a controller. The first light source emits light in a first wavelength range. The second light source emits light in a second wavelength range. The at least one imaging sensor senses light in the first wavelength range reflected off of the scene during a first illumination sensing period and senses light in the second wavelength range reflected off of the scene during a second illumination sensing period. The controller is electrically coupled to the at least one imaging sensor. The controller interprets signals received from the at least one imaging sensor as imaging data, stores the imaging data, and analyzes the imaging data with regard to multiple dimensions. The first illumination sensing period and the second illumination sensing period are discrete time periods.

    Abstract: Systems and methods for producing a lighting design for an event at a venue. One system includes a lighting fixture configured to project a light beam, an input device configured to receive a user input, and a controller including an electronic processor and a memory.

  • Patent number: 11747478
    Abstract: A system for mapping a stage includes a lighting fixture, a scanner, and a controller. The lighting fixture includes a visible light source and an infrared light source. The lighting fixture at least partially illuminates the stage with structured infrared light. The scanner detects the structured infrared light on the stage. The controller is connected to the lighting fixture and the scanner. The controller turns on the visible light source in a visible light mode and turns on the infrared light source in an infrared light mode. The infrared light source illuminates at least a portion of the stage with the structured infrared light. The controller also directs the scanner to scan the structured infrared light on the portion of the stage, receives signals from the scanner as scan data, and translates the scan data into three-dimensional location data.

  • Patent number: 11546982
    Abstract: Systems and methods for determining lighting fixture arrangement information (e.g., position and/or orientation). A lighting beam from the lighting fixture is directed among three discrete locations on a reference surface (e.g., by a controller). The fixture's position is determined using perspective inversion based on angular changes of the lighting fixture and coordinate data of the discrete locations (e.g., determined using a camera and a reference point on the surface). Distances from the fixture to the three discrete locations are estimated based on perspective inversion. The position of the lighting fixture is trilateralized based on the distances. Spherical coordinates of the fixture's orientation relative to the reference surface are determined, and yaw, pitch, and roll of the fixture are extracted.

  • Patent number: 11438978
    Abstract: Systems, devices, and methods for determining and displaying operational parameters of a light fixture that includes narrow band emitters. A controller includes stored information related to spectral power distributions of each of a plurality light wavebands generated by a plurality of narrow band emitters (e.g., LEDs). Based on the spectral power distributions, the controller is configured to determine an output spectrum of the light fixture and/or an output spectrum of individual wavebands. The controller is configured to generate an output display that includes the determined operational parameters associated with the light fixture and a mechanism for manipulating the outputs of the light fixture's wavebands. Using the mechanism, a user can manipulate the operational parameters of the light fixture and observe from the output display a substantially real-time representation of the operational parameters of the light fixture based on the user manipulations.

  • Patent number: 11320117
    Abstract: A light fixture includes a housing, a light source, and a zoom mechanism. The light source is supported within the housing and emits light. The zoom mechanism selectively varies a beam angle of the light emitted from the light fixture and includes a lens and a movable element. The lens is fixed relative to the light source. The movable element is movable relative to the lens between a first position and a second position. The lens reflects a portion of the light emitted by the light source via internal reflection when the movable element is in the first position. The movable element is closer to at least a portion of the lens when the movable element is in the second position to at least partially frustrate the internal reflection.
