    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: 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.

    Abstract: Tenon-mounted lighting fixtures with high structural integrity are provided. In one embodiment, the lighting fixture has a housing that has an integrally formed tenon cradle, which is configured to receive a tenon of a light pole. A light source is also mounted on a bottom side of the housing. The tenon cradle is between a first bolt boss and a second bolt boss, and is in communication with a rear opening of the housing. The first and second bolt bosses may be integrally formed in the housing. The tenon cradle includes multiple ribs. An arcuate cross rib resides in a first plane in which a first bolt shaft of the first bolt boss and a second bolt shaft of the second bolt shaft reside. An axial rib intersects the arcuate cross rib and runs perpendicular to the first plane.

    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 distributed, parallel, image capture and processing architecture provides significant advantages over prior art systems. A very large array of computational circuits—in some embodiments, matching the size of the pixel array—is distributed around, within, or beneath the pixel array of an image sensor. Each computational circuit is dedicated to, and in some embodiments is physically proximal to, one, two, or more associated pixels. Each computational circuit is operative to perform computations on one, two, or more pixel values generated by its associated pixels. The computational circuits all perform the same operation(s), in parallel. In this manner, a very large number of pixel-level operations are performed in parallel, physically and electrically near the pixels. This obviates the need to transfer very large amounts of pixel data from a pixel array to a CPU/memory, for at least many pixel-level image processing operations, thus alleviating the significant high-speed performance constraints placed on modern image sensors.
