ABSTRACT:
A method for manufacturing a flat illumination unit provides light guide channels in the form of transparent rods arranged in lines on the upper side of a plate. The upper side of a plate is coated with a casting compound and, after hardening of the casting compound, the plate is eroded from the opposite side until only the light guide channels remain respectively surrounded on three sides by the casting compound and therewith form a film.
