Abstract
This is directed to a lens for use with a LED light source. The lens can be placed on a top surface of a light fixture to direct light emitted by a LED module at a wide angle relative to the top surface of the fixture. The lens can include an elongated trench in which several LED light sources can be placed in a line such that light emitted within the trench is re-directed by the lens. The lens can include one or more knobs extending over the trench to facilitate diverting emitted light in a more lateral direction, as opposed to vertical direction. In some cases, the lens can be constructed using an extrusion process by which a lens having a constant cross-section allowing for a wide angle radiation pattern is provided.
