Abstract: A fixture configuration module comprises fixture control circuitry and range control circuitry. The fixture control circuitry is configured to control a light fixture to produce light in accordance with 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 range control circuitry is communicatively coupled to the fixture control circuitry and comprises a mechanical switch. The range control circuitry is configured to designate the range to the fixture control circuitry in response to the mechanical switch being positioned into at least one of a plurality of switch positions into which the mechanical switch is positionable.

Abstract: An LED bulb with a down-reflecting optic is disclosed. Embodiments of the present invention can provide for an omnidirectional intensity distribution in the vertical plane for a vertically oriented solid-state lamp. In example embodiments, an optically transmissive enclosure is installed on the driver base. A plurality of LEDs are mounted on a mounting surface of the driver base, and an optical arrangement is disposed at least partially in an optical path from the plurality of LEDs to a central area of the optically transmissive enclosure to down-reflect at least some light from the plurality of LEDs. The optical arrangement can include a TIR optic with a spline-driving surface to down-reflect the at least some light from the plurality of LEDs, or a substantially flat mirror. Either may include a central aperture, and the optical arrangement may include a diffuser or diffusive areas.

Abstract: In one aspect, luminaires are described herein enabling independent thermal management of driver and LED assemblies. For example, a luminaire comprises a driver assembly vertically integrated with a LED assembly, the driver assembly comprising a driver heatsink having an interior in which a circuit board assembly is positioned, and the LED assembly comprising an array of LEDs and LED heatsink, wherein a barrier is positioned between the driver heatsink and the LED heatsink, separating convective cooling of the driver assembly from convective cooling of the LED assembly.

Abstract: An LED-based lighting fixture sets or adjusts a parameter of a drive signal that is used to drive its LEDs to be more compatible with the camera system; the camera system sets or adjusts an image capture parameter to be more compatible with the LED-based lighting fixture, or a combination thereof. The drive signal may be a PWM signal with a variable PWM frequency and/or duty cycle, a variable DC signal, or any combination thereof. The parameter of the drive signal that may be set or adjusted includes, but is not limited to, a PWM period, PWM frequency, PWM duty cycle, amplitude of the active and inactive portions of the PWM signal, and the like. The image capture parameter that may be adjusted includes, but is not limited to, frame rate, frame period, integration time, gain, shutter type (i.e. rolling shutter, global shutter, etc.), and the like.

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.

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.
