Managed Illumination Lightguide

摘要

A lighting system can comprise an edgelit panel, for example a lightguide that may have a panel or slab shape with an edge that receives light from an array of light emitting diodes extending along the edge. The lightguide can guide the received light towards an opposing edge of the lightguide and gradually release light to provide illumination. An optic can manage light that reaches the opposing edge of the lightguide, for example via softening, spreading, concentrating, or diffusing the light. The optic can be mounted to or integrated in the opposing edge of the lightguide.

主权项

1. A lighting system comprising:
a light emitting diode; and a lightguide comprising:
a first face;a second face;a first edge that extends between the first face and the second face and that is disposed adjacent the light emitting diode to receive light emitted by the light emitting diode; anda second edge that extends between the first face and the second face and that is opposite the first edge to emit from the lightguide a portion of the received light; and an optical element that extends along the second edge and comprises a groove in which the second edge is disposed.
