An illuminant that also functions as decorative wallpaper or as an architectural decoration is disclosed. The illuminant may include a light generation part such as an organic light emitting material, a light guide such as a tapered light guide, and a surface pattern. The light source generates the light that is guided to small opening in the surface pattern to provide illumination. The surface pattern may be formed as a decoration or subsequently processed to form the decoration.
