ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a festival formative lamp, and more particularly to a formative lamp with the edge-lighting.
2. Description of Prior Art
In accordance with the conventional festival fancy lamps, most of them are constructed of twining a string lamp on a formative frame. But due to exposing the cords to the air, the whole formative art is affected a bit. So there is another kind of fancy lamp came out later, which is composed of two half of formative frame shells containing the entire string lamp and cords inside, so that the cords are not exposed to the air and the lamps are hidden into the shell.
But there are some shortcomings existing in the above-mentioned formative frame shell lamp as follows:
1. Because the light source is applied of the similarities of the conventional Christmas string lamp, and the light source is not treated in mean scatter, the lamp is looked to as a collected many spot lights in a longer distance, so that the outline of the formative lamp configured by the light of inside string lamp is so soft that the formative outline can not be presented.
2. Due to considering to the transparency of the shell of the formative lamp, the thickness of the shell is moulded into very thin so that the joint portion of the shell and the retainer is easy to be damaged by an extra force as plug the lamp socket of the lamp into the retainer of the shell.
3. Because the lamp is direct installed into inside of the shells, when plug the lamp socket into the thin portion of the pattern of formative lamp, the installation process becomes difficult due to the limited presetting space, it will affect the assembly operating efficiency directly.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore a main object of the present invention to provide a formative lamp that has a brightening outline along the pattern of it.
It is another object of the present invention to a formative lamp with an improved structure, which is easy to be manufactured and assembled, meanwhile the production cost will be decreased.
These objects are achieved by a formative lamp, which is consisted of two half of formative shells and a sandwich lighting plate. Wherein the formative shells are moulded into the desired pattern and outline, and the lighting plate is made of high transmissivity material, and moulded into the pattern outline as same as the shell's. In combination, the string lamps and the cords can be pre-inserted on the lighting plate, finally cover the formative shells from the both sides.
When cut-in the power, the lamps inserted on the lighting plate is lighten, the light ray not only shine through the formative shells, but also via the high transparency lighting plate to generate an edge-lighting source along with the edge of the formative pattern. Hence, due to the brightness difference of the formative shells and the edge-lighting source of the lighting plate, the outline of the formative lamp is drawn out to increase the funny of the product.
When increase the thickness of the lighting plate, it will reinforce the joint portion of the retainer on the lighting plate. And because the lamp sockets are installed on the lighting plate, so the force of plugging the lamp socket cannot damage the formative shells. And due to the lighting plate is flat, plugging the lamp sockets is became easy and convenient.
