ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to a light picture, more particularly, to a luminescent jigsaw picture or pattern serving as a light decorative article on the wall.
2. Description of the Prior Art
A decorative framed wall-picture depicting a historic or scene spot or a cartoon figure will inevitably fade its freshness out gradually in the long run, no matter how attractive its debut could be. Instead, this invention, engaged in a structural breakthrough by putting together luminescent jigsaw pieces to form a light lining with indispensable electric circuits, is to provide a light picture with diversified configurations for keeping its attractiveness.
SUMMARY OF THE INVENTION
The primary object of this invention is to arrange a plurality of luminescent jigsaw pieces to form a lining as light sources for lightening a picture or pattern thereon.
Another object of this invention is to arrange the plurality of luminescent jigsaw pieces together with commensurate conductive lines to form diversified patterns in different light configurations.
Yet another object of this invention is to present diversified colors of the luminescent jigsaw pieces.
Furthermore, the luminescent jigsaw pieces can be designed in relatively larger scale English characters or animals for serving as an advertisement signboard.
For building abovesaid structure, a plurality of conductive lines aligned in a sequence a positive wire prior to a negative or vice versa is formed in a frame body, and a wiring box and a multistage switch are disposed at a peripheral frame beam for switching operation among different circuits. When assembling, a pattern or a picture formed in a translucent material is firstly mounted in a frame, a plurality of luminescent jigsaw pieces is then laid on back of the picture or pattern at where seen fit. Under the layer of the luminescent jigsaw pieces, a transparent conductive layer, a lightening layer, and another conductive layer are introduced one after another so that lightening the pattern and changing the light position in the pattern are made possible.
