Luminaire with integrated lightguide
Abstract
A luminaire can comprise a lightguide, a substrate to which an array of light emitting diodes is mounted, and a cover that extends over the substrate. A light-receiving edge of the lightguide can be positioned adjacent the array of light emitting diodes so that emitted light couples into the lightguide via that edge. The lightguide can guide the coupled light from the light-receiving edge to an opposing, light-emitting edge that emits the coupled light to provide illumination. The cover can comprise an aperture through which the lightguide extends, so that the cover may enclose the light-receiving edge while the light emitting edge may protrude through the aperture.
