Techniques and devices are provided for sensing image data from a scene and activating primary light sources based on information sensed from the scene. Subsets of a plurality of primary light sources may be activated to emit sensing spectrum of light onto a scene. Combined image data may be sensed from the scene while the subsets of the plurality of primary light sources are activated. Reflectance information for the scene may be determined based on the combined image data and combined sensing spectra. Spectrum optimization criteria for the primary light sources may be determined based on the reference information and a desired output parameter provided by a user or determined by a controller. The plurality of primary light sources may be activated to emit a lighting spectrum based on the spectrum optimization criteria.

An embodiment includes eyewear having an optical element, electronic components, a support structure configured to support the optical element and the electronic components, and light emitting diodes (LEDs) coupled to the electronic components and supported by the support structure. The LEDs are positioned to illuminate the support structure according to a lighting scheme.

A display device (1) for displaying a decorative object (2), including a case (4) provided with a support element (5) on which an area of interest (3) is defined, inside which the decorative object (2) is likely to be disposed and/or handled. A processing unit generates a command for controlling the illumination properties of a main illumination device (8a) and/or of a secondary illumination device (8b) as a function of criteria concerning the viewer's visual perception of the object (3) and controls the main illumination device (8a) and/or the secondary illumination device (8b) as a function of the command for controlling the properties of the illumination devices (8a, 8b).

A light fixture includes a housing adapted to secure the light fixture to a building. A lamp may be mounted to the housing. The light fixture further includes an actuator configured to move the device to move between a retracted position and an extended position so that the lamp can illuminate an area around the building.

A liftgate lighting system for a vehicle includes a liftgate assembly having a first liftgate panel and a second liftgate panel. Each of the first liftgate panel and the second liftgate panel is operable between an opened position and a closed position. The second liftgate panel has a proximal end and a distal end. A sensor proximate to the proximal end of the second liftgate panel. The sensor defines a sensor field. A lamp assembly is coupled to the second liftgate panel. A controller is communicatively coupled to the lamp assembly. The controller activates the lamp assembly and the lamp assembly directs light to a ground area proximate to the second liftgate panel when the lower liftgate panel is in the opened position.

A security light having optional and prioritized connection to multiple power supplies. The lighting controller can sense the appropriate connected supply and automatically connect to three different power supplies which include house voltage connection through a typical junction box, a remote solar charging station, and on board batteries that can be used as a third backup power supply. Additional implementations include prioritizing the connection to the plurality of electrical supplies and selecting one of the electrical supplies based upon a stored connection priority list or associated circuitry as well as including associated lighting characteristics for the prioritized selection.

In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

A lighting system has at least one luminaire (1) for illuminating a thoroughfare (10). At least one sensor (11,12,13) detects that a fallen object (30) may be at least partially blocking said thoroughfare (10). A traffic flow monitor (11,12,13) monitors traffic flow along said thoroughfare (10). The light output by the luminaire (1) is controlled to be of a first pattern in accordance with a determination that a fallen object (30) is at least partially blocking said thoroughfare (10). The light output by the luminaire (1) is controlled to be of a second pattern in accordance with the traffic flow monitor (11,12,13) determining that traffic is flowing along said thoroughfare (10).

An image sensor includes an active pixel array including a number of pixels and image sensor control circuitry configured to perform a read operation only on a subset of the pixels of the active pixel array such that pixels not in the subset remain inactive. By reading out only the subset of pixels in the active pixel array and keeping the remaining pixels inactive, the temperature of the active pixel array may be reduced compared to a conventional read out process, thereby reducing thermal noise in the resulting pixel data.
