Abstract: A decorator lamp is composed of a glass body having a surface concave toward the center of the surface and defining a through-hole formed at a desired position of the glass body in such a manner that the outer dense layer of the glass body is removed at the desired position, and a light source placed within the bore. The light source may be formed of a central bulb and a plurality of miniature bulbs arranged underneath the central bulb in such a way that the miniature bulbs are located within the through-hole and when seen in a plan view of the decorator lamp, the miniature bulbs surround the central bulb. The light from the light source is thus reflected back inwardly by the outer dense layer of the glass-made main body. It is also reflected by the walls of lands and recesses formed in the circumference of the glass-made main body. A variety of colors are thus produced at such dense layer, lands and recesses, depending on the angles of reflected light beams, thereby making the decorator lamp useful.
