Abstract: A light fixture for producing a light output. The light fixture includes a control printed circuit board and a light module printed circuit board. The control printed circuit board includes an aperture and a first number of printed circuit board layers. The control printed circuit board has a first surface area. The light module printed circuit board is configured to electrically connect to the control printed circuit board at the aperture to allow light from the light module printed circuit board to pass through the aperture. The light module printed circuit board includes a second number of printed circuit board layers. The light module printed circuit board has a second surface area. The first number of printed circuit board layers is greater than the second number of printed circuit board layers. The first surface area is larger than the second surface area.

Abstract: A lighting control system having a driver for independently controlling multiple light sources. One lighting control system includes an input capable of being driven in a first polarity and a second polarity reversed from the first polarity, a first light source connected to the input and configured to generate light when driven at the first polarity, and a second light source connected to the input and configured to generate light when driven at the second polarity. The lighting control system includes a steering bridge connected to the input and configured to control the polarity of the input, and a controller connected to the steering bridge. The controller is configured to control, based on a steering drive command, the steering bridge, and provide, to the input, lighting control signals to independently control the first light source and the second light source.

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.

Abstract: A method for control of a light fixture, the method including energizing the light fixture to produce a first light output with a first chromaticity and a first spectral power distribution, receiving a user input representative of a desired adjustment of a lighting effect, generating a target spectrum based on the user input, and energizing the light fixture to produce a second light output with the first chromaticity and a second spectral power distribution. The second power distribution approximates the target spectrum.

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: A luminaire including an input driven in a first polarity and a second polarity reversed from the first polarity, a first light source coupled to the input and adapted to generate visible light within a first wavelength range at a first intensity when the input is driven in the first polarity and adapted to generate visible light within the first wavelength range at a second intensity less than the first intensity when the input is driven in the second polarity, and a second light source coupled to the input and adapted to generate light within a second wavelength range, different than first wave length range, at a third intensity when the input is driven in the second polarity and adapted to generate light within the second wavelength range at a fourth intensity less than the third intensity when the input is driven in the first polarity.

Abstract: A lighting fixture including a light source including an array of light emitting diodes (LEDs) and a reflector including a input end adjacent the array of LEDs and an output end opposite the input end such that the light source emits light through the reflector from the input end through the output end. The reflector further includes a first, a second, a third, and a fourth sidewall that extend from the input end to the output end. The first and the second sidewalls each include an interior surface, the third and the fourth sidewalls each include an interior surface having a reflectivity that is more diffuse than the interior surfaces of the first and second sidewalls. A lens is adjacent the output end of the reflector.

Abstract: Methods and systems are provided for directing a lighting fixture in a venue. A user device is paired with a three-dimensional model space that represents a physical space of the venue. A lighting beam destination is indicated with the user device using a position and an orientation of the user device. The indicated lighting beam destination is converted into coordinates in the three-dimensional model space. A lighting fixture orientation value to direct a lighting beam of the lighting fixture to the lighting beam destination in the physical space of the venue is determined based on the coordinates of the lighting beam destination in the three-dimensional model space of the venue. A motor associated with the lighting fixture is actuated to move the lighting fixture to a lighting fixture orientation in the physical space of the venue based on the lighting fixture orientation values.
