Abstract
In one aspect, a lens comprises a light receiving side comprising grooves for receiving light emitting diodes, the grooves defined by refractive walls. The lens also comprises a light extraction side opposite the light receiving side, the light extraction side comprising refractive extraction surfaces diverging light from a central axis of the lens. In some embodiments, the refractive walls of the grooves work in conjunction with the refractive extraction surfaces to diverge light from the central axis of the lens. In some embodiments, luminaire comprises an array of light emitting diodes; and the lens positioned over the array of light emitting diodes.
