Abstract
A light guiding strip and a double-sided planar light apparatus are provided. According to one embodiment of the present invention, the double-sided planar light apparatus includes a plurality of light guiding strips, wherein the plurality of light guiding strips are positioned in a planar arrangement, each of the plurality of light guiding strips including a first plurality of light emitting surfaces disposed toward a first direction and a second plurality of light emitting surfaces disposed toward a second direction, each of the plurality of light guiding strips further including a first end and a second end configured to receive light, wherein the plurality of light guiding strips emit light from the first and second plurality of light emitting surfaces. Reflectors and light diffusion patterns on the light guiding strips provide control and independence over the two sides of the planar light apparatus.
