    Abstract: A linear LED lighting system, assembly and/or fixture distributes luminance efficiently in certain applications, such as for ceiling lighting used in certain retail environments. According to example embodiments of the invention, a linear LED lighting system includes at least two tilted, parabolic reflecting surfaces and a linear array of LED devices, wherein at least some of the LED devices are substantially disposed at a focus line of at least one of the tilted, parabolic reflecting surfaces. A diffuser or diffusive lens can be disposed adjacent to the parabolic reflecting surfaces where light exits the system to provide color mixing and/or eliminate potential hot spots. The tilt of the reflecting surfaces can be changed to adjust the illumination pattern. A lighting system according to example embodiments of the invention can be designed for retrofit installation or as a complete fixture.

    Abstract: A sensor module for a lighting fixture includes a module housing configured to be mounted to a lighting fixture, a light sensor mounted in the module housing, and a sensor cover over the light sensor. The sensor cover includes a first surface oriented to face a task surface within an area of interest, and a second surface opposite the first surface. The first surface includes a first Fresnel lens having a number of Fresnel ridges oriented in a first direction. The second surface includes a second Fresnel lens having a number of Fresnel ridges oriented in a second direction, which is different from the first direction. Providing the first Fresnel lens and the second Fresnel lens with differently oriented Fresnel ridges allows the sensor cover to focus light from a relatively large portion of the task surface to the light sensor while remaining small.

    Abstract: A sensor module for a lighting fixture includes a housing configured to be mounted to a lighting fixture, a light sensor mounted in the housing, and a sensor cover over the light sensor. The sensor cover includes a parallel surface and an angled surface. The parallel surface is parallel to a task surface within an area of interest, and includes a first number of lens sections, each of which are configured to focus light from a different portion of a first subset of the task surface to the light sensor. The angled surface includes a second number of lens sections, each of which extend from an edge of the parallel surface to form a facet of the angled surface and are configured to focus light from a different portion of a second subset of the task surface to the light sensor.

    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: 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.
