  • Patent number: 10386571
    Abstract: A system of light emitting diodes and lightguides can produce and distribute light in a luminaire. Two or more lightguides can be mounted adjacent one another so that their edges extend alongside one another. An optic can couple light between the light emitting diodes and the edges of the adjacent lightguides. The optic, which can be another lightguide in some examples, can mix, blend, or homogenize light received from the light emitting diodes and distribute the light among the adjacent lightguides. The optic can mix light emitted from multiple light emitting diodes so that light enters the adjacent lightguides uniformly along the edges of the lightguide, thereby eliminating or reducing any bright spots or visual inconsistencies. The optic can further allocate light uniformly among the adjacent lightguides.
