Abstract:
A light emitting sign including a lightguide having a thickness not greater than 0. 5 millimeters. The lightguide having an array of elongated legs extending therefrom, wherein each leg terminates in a bounding edge and is folded such that the bounding edges are stacked. At least one light source emits light into the stacked bounding edges. The light travels within the legs to the lightguide, with the light from each leg combining and totally internally reflecting within the lightguide. A plurality of light scattering features frustrate totally internally reflected light within the lightguide such that the light exits the sign in a light emitting area.
