Abstract: A fixture configuration module comprises range control circuitry and fixture control circuitry. The range control circuitry is configured to store a range of a lighting parameter. The range identifies at least a subset of values of the lighting parameter supported by the light fixture to produce light. The fixture control circuitry is communicatively coupled to the range control circuitry and is configured to control the light fixture to produce the light in accordance with the range stored by the range control circuitry.

Abstract: A lighting fixture includes a solid-state light source, communications circuitry, and control circuitry coupled to the communications circuitry and the solid-state light source. The control circuitry is configured to receive a message from a neighboring device via the communications circuitry, the message indicating the detection of an occupancy event by the neighboring device. Further, the control circuitry is configured to adjust a light output provided by the solid-state light source based on a neighbor ranking of the neighboring device, wherein the neighbor ranking indicates a number of intermediate devices located between the lighting fixture and the neighboring device.

Abstract: A lighting fixture including a light source, a housing, an image sensor, and a lens is disclosed. The housing is coupled to the light source and includes an opening through which light from the light source is emitted to fill an illumination area. The image sensor is configured to capture one or more images of the illumination area. The lens is over the image sensor, and provides the image sensor a field of view that substantially corresponds with the illumination area. By tailoring the lens such that it provides the image sensor a field of view that substantially corresponds with the illumination area, the image sensor can collect information relevant to the lighting fixture.

Abstract: A lighting fixture includes a fixture body, a lighting bay, a light source, and an auxiliary bay. The lighting bay is in a first portion of the fixture body. The light source is in the lighting bay, and is configured to provide light suitable for general illumination. The auxiliary bay is adjacent to the lighting bay in a second portion of the fixture body. The auxiliary bay includes a mounting surface suitable for mounting an auxiliary device in the auxiliary bay and an auxiliary bay frame surrounding the auxiliary bay, which supports and therefore allows for the installation of a removable auxiliary bay cover over the auxiliary bay. Providing the auxiliary bay in the fixture body allows auxiliary devices to be installed in a ceiling without any changes to the ceiling.

Abstract: A frame is obtained from an image sensor. The frame may include a number of zones, each of which in turn includes a number of pixels. Each one of the pixels may be associated with a pixel value. A pixel change value for each one of the pixels in the frame may be determined based on an average pixel value of the pixel over a number of frames. The pixel change value for each pixel may then be normalized based on an average zone change value for the zone in which the pixel is located. The average zone change value may be based on the pixel change value for each one of the pixels in the zone. By using the average zone change value to normalize the pixel change value, an image frame may be analyzed in an efficient and fast manner.

Abstract: A method includes the steps of obtaining distance measurements between a device and a number of lighting fixtures, processing the distance measurements to assign coordinates to each one of the lighting fixtures, and facilitating registration of the coordinates of a subset of the lighting fixtures to obtain registered coordinates for all of the lighting fixtures. The coordinates indicate a relative location of each one of the lighting fixtures with respect to one another. The registered coordinates indicate a location of each lighting fixture in a desired coordinate space. Accordingly, a location of a lighting fixture within a desired coordinate space can be easily obtained, which may enable significant additional functionality of the lighting fixture.

Abstract: A lighting fixture includes an outer frame, a solid-state light source, a lens, and a sensor module connector. Driver circuitry is coupled to the outer frame and provides one or more drive signals for powering the light source. The lens is supported by and attached to the outer frame. The solid-state light source is mounted to the outer frame and at least partially surrounded by the lens, such that at least a portion of the light provided by the solid-state light source is transmitted through the lens towards an area of interest. The sensor module connector is mounted to the outer frame and configured to accept a connector from a sensor module such that when the sensor module is installed in the lighting fixture, a surface of the sensor module faces the area of interest towards which light from the solid-state light source is provided.

Abstract: A lighting fixture includes a control system, a light source, and an image sensor module. The image sensor module is configured to capture image data and process the image data to provide derived image data, such that the derived image data is downsampled from the image data. The derived image data is used by the control system to adjust one or more characteristics of light provided by the light source.
