发明名称 ILLUMINATION APPARATUS
摘要 A point light source is converted into a plane light source having a satisfactory uniformity. The point light source is converted into a line light source by means of a linear light guiding plate, and further into the plane light source by means of a plane-like light guiding plate. Light from the point light source is reflected at a lamp reflector to be incident on at least two side surfaces of the plane-like light guiding plate.
