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: An optical waveguide body includes first and second pluralities of light extraction features disposed on a first side of the waveguide body and adapted to direct light out of the waveguide body through a second side of the waveguide body opposite the first side. Each of the first plurality of light extraction features has a linear shape and each of the second plurality of light extraction features has at least one of a piecewise linear shape and a nonlinear shape. The piecewise linear shape comprises two adjacent planar surfaces with an angle therebetween of at least about 30 and at most about 180 degrees. The waveguide body further has a light coupling cavity.

Abstract: A lighting device comprises a body of optically transmissive material exhibiting a total internal reflection characteristic, the body further comprising a light input surface for receiving light, a light extraction portion spaced from the light input surface, a light transmission portion disposed between the light input surface and the light extraction portion, and at least one light deflection surface for deflecting light toward the light extraction portion. Further in accordance with this aspect the light extraction portion comprises a first extraction surface for extracting light deflected by the at least one light deflection surface out of the body and a second extraction surface for extracting light other than light deflected by the at least one light deflection surface out of the body.

Abstract: A sensor module for a lighting fixture includes a light sensor and a sensor cover over the light sensor. The sensor cover includes a front surface and a light focusing surface opposite the front surface. The front surface is configured to face an area of interest that is generally illuminated by the lighting fixture. The light focusing surface is opposite the front surface and includes a number of lens sections, each of which is configured to focus light from a different portion of the area of interest toward the light sensor. By including a number of lens sections each focusing light from a different portion of the area of interest, a relatively large area of interest can be observed while maintaining desirable aesthetics of the sensor module.
