Abstract
A light emitting diode device which includes at least one light emitting diode, a heat-sink chassis having a surface upon which the at least one light emitting diode is mounted, and a waveguide having one end coupled to the at least one light emitting diode for receiving light therefrom. The waveguide has another end which includes a light extraction and redistribution region, and the waveguide is configured to guide light received from the at least one light emitting diode away from the heat-sink chassis and towards the light extraction and redistribution region. The light extraction and redistribution region is configured to extract and redistribute the light from the waveguide.
