Abstract
Embodiments of the invention include a plurality of semiconductor light emitting diodes attached to a mount. A plurality of lenses are disposed over the plurality of semiconductor light emitting diodes. A lens disposed over a semiconductor light emitting diode proximate an edge of the mount is rotationally asymmetrical and is shaped such that for a portion of the lens light emitted at an intensity that is half a maximum intensity is emitted at an angle of at least 70° relative to a normal to a top surface of the semiconductor light emitting diode.
