Abstract: A light fixture has a linear LED array and a lens having a first surface and a second surface that covers the LED array. The light being received at the first surface and emitted from the second surface. The lens includes a plurality of light shaping features on at least one of the first surface and the second surface where the plurality of light shaping features are configured to generate a directional light distribution pattern. The light pattern may be symmetric or asymmetric relative to a longitudinal axis of the light fixture. The lens may comprise a plurality of sections where the plurality of sections made of material having different optical properties.

Abstract: A modular overhead lighting system includes a raceway element and one or more interchangeable lighting modules capable of variable positioning relative to the raceway element. Multiple raceway conductors are mounted in the raceway element, with a portion of each raceway conductor being exposed along a lower surface thereof to facilitate continuously variable positioning of lighting modules. An electrical connector for establishing electrical connections between a raceway element and a lighting module includes multiple ridges incorporating electrical contacts configured to contact raceway conductors, and includes terminals to removably receive electrical wires permitting electrical communication between a lighting module and the raceway element.
