Abstract

A lighting fixture made in the form of a wall (floor) tile or a light box is disclosed to include a holder base holding a substrate, a plurality of light emitting devices, for example, LEDs or luminescent lamps installed in the substrate and electrically connected to together, and a cover shell, which is directly molded on the holder base and the substrate and the light emitting devices and has a patterned light-permeable area for the passing of the light from the light emitting devices.

Claims

1. A lighting fixture comprising:

a holder base;

a substrate fixedly mounted on said holder base;

a plurality of light emitting devices installed in said substrate and electrically connected to together; and

a cover shell package covering said holder base and said substrate and said light emitting devices.

2. The lighting fixture as claimed in claim 1, wherein said substrate is selected from one of board members including printed circuit board, polycarbonate board and acrylic board, having a circuit arranged thereon and electrically connected to said light emitting devices and an electric wire for connection to external electric means.

3. The lighting fixture as claimed in claim 1, wherein said light emitting devices are selected from:

light emitting diodes, luminescent lamps, and their combination.

4. The lighting fixture as claimed in claim 1, wherein said cover shell is molded from a resin mixture containing hard grain members selected from sands, glass grains, metal grains and ceramic grains.

5. The lighting fixture as claimed in claim 1, wherein said cover shell is molded from a resin mixture containing a fire retardant.

6. The lighting fixture as claimed in claim 1, wherein said cover shell is molded from a resin that guides lights.

7. The lighting fixture as claimed in claim 6, wherein said cover shell is molded from a resin containing at least one color pigment.

8. The lighting fixture as claimed in claim 1, wherein said cover shell has a light-permeable area that shows a predetermined pattern, and an opaque area surrounding said light-permeable area.

9. The lighting fixture as claimed in claim 1, which has the shape of a tile for construction.

10. The lighting fixture as claimed in claim 1, wherein said cover shell has light-permeable chips fixedly fastened the outer surface thereof and the area of the outer surface beyond said light-permeable chips darkened to block light.
