  "claims": [
    "1. A lighting display device comprising: a frame including a base on which a front frame body and a rear frame body are arranged; a film-coated glass mounted on the front frame body and having the front side with light transmittancy facing towards the front frame body as a window surface and the back side with reflectivity; a mounting seat arranged on the base, between the front frame body and the rear frame body with a positioning hole arranged thereon, on the inner periphery of which at least one positioning protrusion is arranged; a projecting device including at least one projecting light, disposed in an engaging room under the positioning hole of the mounting seat with a projecting light source thereof aiming at the positioning hole; a support bracket with the lower end thereof arranged on the base of the frame and a lighting source arranged on the upper end thereof; a transparent bottle filled with a filler of liquids with the bottom thereof being able to be fixed on the positioning hole of the mounting seat by spinning and located above the projecting device, corresponding to the height of the window surface; a first reflection mirror and a second reflection mirror fixed on the rear frame body, located behind the transparent bottle and having the reflection surfaces thereof facing forward, and a center thereof serving as a reference to define the first and second reflection mirrors symmetrically, inclined to form an angle θ between 145° and 175°, so that the window surface would display an unlimited extension of an inward serial arrangement of the transparent bottle from the middle after the contents thereof are reflected repeatedly and cumulatively by the first and second reflection mirrors; and a cover plate disposed on the rear frame body, behind the first and second reflection mirrors.",
    "2. The lighting display device as claimed in claim 1, wherein the first and second mirrors behind the rear frame body form an angle θ and have two symmetrical inclined surfaces to form a pre-determined slope when they are joined together.",
    "3. The lighting display device as claimed in claim 1, wherein the projecting device further includes a lamp base for the projecting light to be arranged thereon, and the projecting light includes a LED light or a bulb.",
    "4. The lighting display device as claimed in claim 3, wherein the projecting light is a LED light, and the bottom of the transparent bottle has contact with the top of the LED light where a heat conductive plaster is arranged thereon in order to conduct the heat to the transparent bottle.",
    "5. The lighting display device as claimed in claim 1, wherein the base has a power supply disposed inside and connected to the projecting device to supply the electric power.",
    "6. The lighting display device as claimed in claim 1, wherein the transparent bottle includes a lava lamp or a glitter lamp.",
    "7. The lighting display device as claimed in claim 1, wherein the bottom of the transparent bottle has at least one thread on the inner periphery for the positioning protrusion of the positioning hole to be fixed thereon by spinning.",
    "8. The lighting display device as claimed in claim 1, wherein the support bracket is arranged in an L shape and is hollow for the power supply to connect to an electric wire through which to supply the electric power for the lighting source on which a lampshade is covering."

  "description_excerpt": "This patent application is a continuation-in-part of Ser. No. 13/535,559 filed on Jun. 28, 2012, currently pending.\n\n1. Field of the Invention\n\nThe present invention relates to a lighting display device, particularly to one that not only has features of the original patent application but can further display a wider area and has the transparent bottle thereof to be fixed inside the positioning hole thereof by spinning.\n\n2. Description of the Related Art\n\nA 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 which has a high density than the liquid at room temperature and a lower density than the liquid 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 a plurality of glitters are put together with the liquid, 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.",
