Abstract
A multiple waveguide edge lit structure includes a frame structure. The multiple waveguide edge lit structure also includes a circuit board including a first plurality of light emitting diodes (LEDs) and a second plurality of LEDs. The multiple waveguide edge lit structure further includes a first waveguide and a second waveguide. A light receiving edge of the first waveguide is positioned proximal to the first plurality of LEDs, and a light receiving edge of the second waveguide is positioned proximal to the second plurality of LEDs. The multiple waveguide edge lit structure also includes a pair of attachment structures configured to keep the first waveguide and the second waveguide attached to the frame structure.
