1. Field of the Invention
The present invention relates to an improved structure of a lighting display device, particularly to one that can replace a lighting object thereof and stably fix the position of the lighting object.
2. Description of the Related Art
A lava lamp display device disclosed in U.S. Pat. No. 3,570,156 comprises a glass vessel having a bottom arranged in a hollow conical metallic seating and located on an electric light bulb. Moreover, the glass vessel has two immiscible components, for example, liquid and paraffin. Paraffin has a higher density than liquid at room temperature and a lower density after heating. After the electric light bulb is turned on, the paraffin at the bottom of the glass vessel is heated and flows in the liquid. At the same time, the electric light bulb projects the light to the glass vessel, forming a lighting effect which becomes a decoration at homes and offices. In addition, if the liquid has a plurality of glitters as contents, the glitters would move and flow with the liquid; such application is called a glitter lamp. However, the lava lamp display device or the glitter lamp only has lighting effects in a single glass vessel. As a decoration, it seems to be monotonous and lacking of visual effects.
Therefore, the inventor has disclosed a lighting object disposed in a frame body with a window at the front that would display an inward serial arrangement of lights and moving shadows from the middle with non-parallel reflection surfaces being repeatedly reflected, creating a mixed feature combining a lighting fixture with an artificial decoration with special visual effects. However, there is only a front window displaying the visual effects of lights and moving shadows, which confines the visual area for the audience; and the transparent bottle as the lighting object needs to be maintained and replaced regularly, which would cause inconveniences for the users as well, leaving the invention to be improved.
A primary object of the present invention is to provide an improved structure of a lighting display device that can replace a lighting object thereof and stably fix the position of the lighting object.
To achieve the objects mentioned above, the present invention comprises a base; a mounting seat perpendicularly arranged on the base with the top thereof having an opening; a circuit module disposed in the mounting seat as the lighting source and the heating source; a lighting object formed by a light-emitting transparent bottle with a top and a bottom, the bottom thereof being disposed on the opening of the mounting seat; and a supporting bracket having the foot thereof disposed on the base; wherein an engaging element is arranged at the top of the supporting bracket to engage a positioning element; the positioning element is connecting a linking tool aside and the bottom end of the linking tool is mounted on the engaging element so that the positioning element and the mounting seat are arranged on the same axis perpendicular to the base; the positioning element is detachable from the supporting bracket for placing the lighting object on the mounting seat and fixing the position thereof
In a preferred embodiment, the linking tool may be arranged in an L shape with an end thereof linking to the positioning element and the other end thereof being mounted on the engaging element, and the linking tool and the engaging element each has a positioning hole arranged at the corresponding position to each other, and the positioning holes are fixed in position by a screw or a bolt.
In an embodiment, the lighting object is a lava lamp or a glitter lamp, and the transparent bottle thereof is filled with heat-sensitive liquid that would flow around when receiving heat; near the top of the transparent bottle an engaging portion with a diameter less than the one of the transparent bottle is arranged, and a top end with a much less diameter than the one of the engaging portion is arranged at the top of the transparent bottle; the bottom of the transparent bottle has an inserting section with a diameter less than the one of the transparent bottle to be mounted on the mounting seat. The inner edge of the positioning element is arranged in a shape to be mounted on and fix the engaging portion of the transparent bottle; or it can be arranged in a shape to be mounted on and fix the top end of the transparent bottle in another embodiment.
In an embodiment, the positioning element has a lighting source disposed atop, and the supporting bracket is hollow for a stretchable wire to pass through; the stretchable wire is connected to the lighting source above the positioning element and to a power supply as well, so as to provide electricity for the lighting source. The present invention further includes a body disposed on the base with an opening arranged atop, including: a light-transmitting front surface; a rear surface; a film-coated glass arranged on the front surface with the front of the film-coated glass being light-transmitting and the back being reflective, forming a window at the front of the body; and a first reflection mirror and a second reflection mirror being fixed on the rear surface of the body behind the transparent bottle and having the reflection surfaces facing towards the transparent bottle.
With the features stated, the body further includes a first bottom surface having a first through hole arranged thereon, and the mounting seat includes a second bottom surface having a second through hole arrange thereon, corresponding to the first through hole; the base has a third through hole corresponding to the first and second through hole; the circuit module has a heat dissipating element, at the bottom of which a threaded hole is arranged to engage an upper section of a hollow bolt; the hollow bolt further has an abutting portion arranged above a lower section thereof for abutting on the base as the lower section being engaged through the first, second, and third through holes, then fixed on the base by a nut, so that the mounting seat and the body are fixed on the base, and an electric wire is able to pass through the base and connect to the circuit module for electricity supply.
As structures disclosed above, the present invention has a detachable positioning element for replacement of the lighting object and stably fixing the position of it. Also, the body has surrounding surfaces to increase the visual area by having the surfaces on both sides projecting the lights and moving shadows of the contents in the lighting object, enriching the visual effects and making it easier for replacement and maintenance.

The body 20 is disposed on the base 10 with an opening 23 arranged atop, including a light-transmitting front surface 21, a rear surface 22, a film-coated glass 40 arranged on the front surface 21 with the front of the film-coated glass 40 being light-transmitting and the back being reflective, forming a window at the front of the body 20.
The mounting seat 50 is perpendicularly arranged on the base 10 with the top thereof having an opening 51; the circuit module 60 is disposed in the mounting seat 50 as lighting and heating source.
The lighting object 70 is formed by a light-emitting transparent bottle 70a with a top 72 and a bottom 71; the bottom 71 thereof is mounted on the opening 51 of the mounting seat 50.
The first reflection mirror 40a and the second reflection mirror 40b are fixed on the rear surface 22 of the body 20 behind the transparent bottle 70a, and have two reflection surfaces 41 of the reflection mirrors 40a, 40b facing towards the transparent bottle 70a. The supporting bracket 80 has the foot thereof disposed on the base 10.
The lighting object 70 is a lava lamp or a glitter lamp, and the transparent bottle 70a thereof is filled with heat-sensitive liquid that would flow around when receiving heat; near the top 72 of the transparent bottle 70a an engaging portion 721 with a diameter less than the one of the transparent bottle 70a is arranged, and a top end 722 with a much less diameter than the one of the engaging portion 721 is arranged at the top 72 of the transparent bottle; the bottom 71 of the transparent bottle 70a has an inserting section with a diameter less than the one of the transparent bottle 70a to be mounted on the mounting seat 50.
