Abstract: A lighting device has a base body of translucent material, in which several light-emitting diodes, which are applied to a flexible adhesive strip having integrated conductors, are arranged at intervals. A cavity is milled into the rear of the base body, the width and length of the cavity being slightly smaller than the width and length of the base body. A closed edge web is created along the periphery of the base body. An adhesive strip having light-emitting diodes is applied to the interior side of the edge web over the entire length in such a way that light-emitting diodes are arranged on the interior sides of opposing edge web sections. The light-emitting diodes illuminate a solid section of the base body in front of the cavity and produce a high luminous density on the front side. The rear side of the cavity is closed by a cover.
