Abstract
A lens comprises a light receiving side comprising grooves for receiving light emitting diodes, the grooves defined by a central refractive region and walls comprising total internal reflection faces; and a light extraction side opposite the light receiving side, the light extraction side comprising refractive extraction surfaces, total internal reflection extraction surfaces, or combinations thereof. In some embodiments, luminaire comprises an array of light emitting diodes, and the lens positioned over the array of light emitting diodes.
