Abstract
In one embodiment, a light-emitting apparatus includes a plurality of adjacent, overlapping light-guide plates formed of substantially transparent material, and a plurality of light sources. Each of the light-guide plates has i) first and second ends, ii) one or more substantially transparent surfaces through which light is emitted, and iii) one or more reflective surfaces to redirect light within the light-guide plate. Where first and second light-guide plates are adjacent, the first end of the first light-guide plate A) underhangs the second end of the second light-guide plate, and B) is positioned opposite a primary light-emitting side of the apparatus. The plurality of light sources are optically coupled to the first ends of the light-guide plates so as to illuminate the interiors of the light-guide plates.
