2. Description of the Related Art
A conventional ceiling fitting is mounted on the ceiling of a house room to provide an illuminating function. In general, the conventional ceiling fitting is affixed to the ceiling by a plurality of fasteners, such as screws or expansion bolts, during the assembling process. The conventional ceiling fitting includes a mounting disk attached to the ceiling, a light emitting member (such as an LED) mounted in the mounting disk, and a lampshade mounted on the mounting disk and covering the light emitting member. However, the lampshade has a curved face with a constant curvature, such that the lampshade only provides a monotonous lighting effect and cannot satisfy the consumer's diverse requirements. In addition, the lampshade has a single structure, thereby decreasing the aesthetic quality of the ceiling fitting.
The primary objective of the present invention is to provide an art lamp with an optical application.
In accordance with the present invention, there is provided an art lamp comprising a mounting disk, a light source module, an inner lampshade, and an outer lampshade. The light source module is mounted on a bottom face of the mounting disk. The inner lampshade is mounted on the bottom face of the mounting disk and surrounds the light source module. The inner lampshade includes a main body and a plurality of locking portions arranged on a periphery of the main body. The locking portions of the inner lampshade are locked onto the mounting disk. The main body of the inner lampshade has a lower surface provided with a plurality of diamond cones extending downward. Each of the diamond cones of the main body is provided with a plurality of light output faces that are inclined and directed toward different directions. The outer lampshade is mounted on the bottom face of the mounting disk and surrounds the inner lampshade. The outer lampshade includes a fitting frame, a plurality of ornament units, and a plurality of connecting members. The fitting frame is mounted on the mounting disk. Each of the ornament units includes an outer ring, and a plurality of crystals mounted in the outer ring. The outer rings of the ornament units are connected with each other to construct an integrity. The crystals of adjacent two of the ornament units are detachably connected by one of the connecting members.
