Light Guide Panel (LGP) is a transparent acrylic panel made from pure PMMA resin, on whose a line matrix is scratched or bottom face dot matrix is printed. The light source can be installed on its edge(s). It distributes the light coming from the light source evenly over the whole upper face of the acrylic panel. Its key components are to maximize the uniformity of light, to make back light slim and to recreate the line or dot light source such as fluorescent, decoration lamp or LED to the panel light source.
