Abstract
A uniform reflective light-guide apparatus can accompany an optional edge light source and includes a light-guiding layer, a reflective layer and a light-exiting surface. The light-guiding layer further has a lateral side to define a light-introducing surface for allowing entrance of lights from the edge light source. The reflective layer is to reflect incident lights back to the light-guiding layer. The light-exiting surface perpendicular to the light-introducing surface is to allow at least a portion of the lights in the light-guiding layer to leave the light-guide apparatus. The reflective layer and the light-guiding layer are manufactured integrally by a co-extrusion process so as to avoid possible existence of an air spacing between the reflective layer and the light-guiding layer.
