     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The 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. 
     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 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. 
     Also, the lava lamp display device and the glitter lamp are both decorations with lighting and water-flow changes inside a single transparent bottle only, which seem to be monotonous and lacking of visual effects as decorations; in other words, there is still room for improvement in these devices. To improve the invention from the prior art, the mentioned original US Patent application disclosed a permeable vision window in the middle of the front side of the frame to displace the lighting object which forms an unlimited extension of an inward serial arrangement from the middle when the non-parallel reflection surfaces are reflected repeatedly, making the invention as a lamp and decoration with special visual effects. However, the vision window is only a small area at the front side of the lamp, leaving the invention to be improved as well. 
     SUMMARY OF THE INVENTION 
     A primary object of the present invention is to provide a lighting display device that has features of the original application, displaying an unlimited extension of an inward serial arrangement of a transparent bottle of the lighting object in the middle when the non-parallel reflection surfaces are reflected repeatedly, and further widens the visual angle and visual area as well. 
     Another object of the present invention is to provide a lighting display device that is easy for assembling and maintaining. 
     To achieve the objects mentioned above, the present invention comprises 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 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 from the middle after the contents of the transparent bottle 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. 
     In an applicable embodiment, 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. Additionally, the projecting device further includes a lamp base for the projecting light to be disposed thereon, and the projecting light can be a LED light or a bulb. Further, when the projecting light is a LED light, the bottom of the transparent bottle has contact with the top of the LED light where a heat conductive paster is arranged thereon in order to conduct the heat to the transparent bottle. Besides, the base has a power supply disposed inside and connected to the projecting device to supply the electric power for the device. 
     In an applicable embodiment, the transparent bottle can be a lava lamp or a glitter lamp. 
     In a preferred embodiment, the bottom of the transparent bottle has at least one thread on its periphery for the positioning protrusion of the positioning hole to be fixed thereon by spinning. 
     In a preferred embodiment, 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. 
     As structures disclosed above, the present invention not only has a window surface to enlarge the area of the unlimited extension of an inward serial arrangement of the transparent bottle from the middle, but can further display a wider area of visual effects. Also, the transparent bottle thereof is easy for assembling and maintaining.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIGS. 1-8 , in a preferred embodiment, the present invention comprises a frame  10 , a film-coated glass  20 , a mounting seat  32 , a projecting device  13 , a support bracket  30 , a transparent bottle  40 , a first reflection mirror  50 A, a second reflection mirror  50 B and a cover plate  60 . 
     The frame  10  includes a base  14  on which a front frame body  31 F and a rear frame body  31 R are arranged. The front frame body  31 F and the rear frame body  31 R can be assembled by a plurality of tappets  31  but are not limited to such application. 
     The film-coated glass  20  is mounted on the front frame body  31 F by a positioning element  21  or adhesive substances and has the front side with light transmittancy facing towards the front frame body  31 F as a window surface  20 ′ and the back side with reflectivity; in other words, the visual area of the present invention is not restricted to a small window but a wide area of a window surface  20 ′. 
     The mounting seat  32  is arranged on the base  14 , between the front frame body  31 F and the rear frame body  31 R and having a positioning hole  33  arranged thereon. On the inner periphery of the positioning hole  33  at least one positioning protrusion  331  is arranged. In the embodiment, the positioning protrusion  331  comprises a plurality of convexities but is not limited to such application; it can also be in a shape of a thread. 
     The projecting device  13  has at least one projecting light  131  and is disposed in an engaging room  322  under the positioning hole  33  of the mounting seat  32  with its projecting light source aiming at the positioning hole  33 . In this embodiment, the positioning hole  33  and the engaging room  322  are linked up, and the projecting device  13  further includes a lamp base  132  for the projecting light  131  to be disposed thereon; the projecting light  131  can be a LED light or a bulb. 
     The support bracket  30  has its lower end arranged on the base  14  of the frame  10  and its upper end having a lighting source  70  arranged thereon. In this embodiment, the support bracket  30  is arranged in an L shape, but is not limited to such application. 
     With reference to  FIGS. 7 and 7A , the transparent bottle  40  is filled with a filler  43  of liquids and the bottom  41  thereof is able to be disposed on the positioning hole  33  by spinning, and it is vertically located above the projecting device  13 , corresponding to the height of the window surface  20 ′. The bottom of the transparent bottle  40  has at least one thread  411  on the inner periphery for a positioning protrusion  331  of the positioning hole  33  to be fixed thereon by spinning, making the transparent bottle  40  easy for assembling and maintaining. In  FIG. 7A , the projecting light  131  is a LED light, and the bottom of the transparent bottle  40  has contact with the top of the LED light  131  where a heat conductive paster  132  is arranged thereon in order to conduct the heat to the transparent bottle  40 . Or the projecting light  131  can be a bulb as shown in  FIG. 7B . In such case, the heat conductive paster  132  is not needed since the bulb has higher watts to provide the heat for the filler  43  of liquids inside the transparent bottle  40  to flow around without the heat conductive paster  132 . 
     Since the transparent bottle  40  needs electric power, in a preferred embodiment, the base  14  has a power supply  16  disposed inside and connected to the projecting device  13  to supply the electric power. The power supply  16  can be a transformer or an electric supplier disposed inside the base  14 ; connecting to an external electric wire  161  and an external transformer is also applicable. In this embodiment, the transparent bottle  40  can be a lava lamp or a glitter lamp. 
     The first reflection mirror  50 A and a second reflection mirror  50 B are fixed on the rear frame body  31 R and located behind the transparent bottle  40 . The back sides thereof are spread over a layer of reflector  51  and the reflection surfaces  52  thereof are facing forward; a center thereof serves as a reference to define the first and second reflection mirrors  50 A,  50 B symmetrically, inclined to form an angle θ between 145° and 175°, so that the window surface  20 ′ would display an unlimited extension of an inward serial arrangement of the transparent bottle  40  from the middle after the contents thereof are reflected repeatedly and cumulatively by the first and second reflection mirrors  50 A,  50 B. 
     The cover plate  60  is disposed on the rear frame body  31 R behind the first and second reflection mirrors  50 A,  50 B. In this embodiment, the cover plate  60  is fixed on the inclined faces  321  of the rear frame body  31 R together with the first and second reflection mirrors  50 A,  50 B by a plurality of positioning elements  61 . The cover plate  60  functions as a protection for the first and second reflection mirrors  50 A,  50 B. The surface area of the cover plate  60  is larger than the ones of the first and second reflection mirrors  50 A,  50 B, so as to protect them from external impacts. 
     As presented in  FIG. 7 , in this embodiment, the support bracket  30  is hollow for the power supply  16  to connect to an electric wire  162  through which to supply the electric power for the lighting source  70  on which a lampshade  71  is covering, making the present invention a lighting fixture. 
     Moreover, referring to  FIGS. 1 and 6 , the first and second mirrors  50 A,  50 B behind the rear frame body  31 R form an angle θ and have two symmetrical inclined surfaces  131  to form a pre-determined slope when they are joined together. In an applicable embodiment, the angle θ between 145° and 175° is the most preferred angle, repeatedly and cumulatively reflecting at least 6 reflections of the transparent bottle  40  and displaying an extended three-dimensional visual effect. 
       FIG. 8  illustrates the practical applications of the present invention. When the present invention is turned on, the transparent bottle  40  would display visual effects of flowing glitters  44 . When the transparent bottle  40  is placed between the film-coated glass  20  and the first and second mirrors  50 A,  50 B as presented in  FIG. 6 , the flowing glitters  44  of the single transparent bottle  40  would be reflected repeatedly and cumulatively as shown in  FIG. 8 , displaying an unlimited extension of an inward serial arrangement of the transparent bottle  40  from the middle  40   a ,  40   b ,  40   c , . . .  40   n . The reflection is rich in visual effects instead of being a monotonous display. 
     With structures disclosed above, the present invention can not only display an unlimited extension of an inward serial arrangement of the transparent bottle  40  from the middle, but can further display a wider area of visual effects. Also, the transparent bottle  40  thereof is easy for assembling and maintaining. 
     Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
