DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 2 through 7, the preferred embodiment of a lava lamp display device in accordance with the present invention comprises: a frame 10, a film-coated glass 20, a support bracket 30, a transparent bottle 40, two pieces of reflection mirrors 50a, 50b, and a cover plate 60.
The frame 10 includes an opening at a back side thereof, a permeable vision window 11 at a middle of front side thereof, and a lamp base 12 and a projection light 13 at a bottom of inner side thereof. In this embodiment, the frame 10 has a base 14 arranged at a bottom surface thereof. With the reference to FIGS. 8 and 9, the frame 10 may have an illuminating light source 70 and a lamp shade 71 arranged at a top surface thereof; such that, the present invention may be an illumination lamp.
The film-coated glass 20 is mounted on the vision window 11 and includes a front side with light transmittancy and a reverse side with reflectivity, which are physical characteristics of the film-coated glass 20 and thus will not be described in details here. In this embodiment, the front side of film-coated glass 20 faces toward an external part of the vision window 11.
The support bracket 30 is arranged in the frame 10 and has at least one positioning hole 33 thereon. As shown in FIG. 2, the support bracket 30 includes two standing plates 31, an upper transom plate and a lower transom plate 32 are arranged between the two standing plates 31; the two positioning holes 33 are respectively arranged at a middle of the upper transom plate and the lower transom plate 32, and the positioning hole 33 of the lower transom plate 32 has a metal ferrule 34 with an opening facing upward for placing the bottom 41 of the transparent bottle 40.
The transparent bottle 40 corresponding to a height of the vision window 11 is arranged in the positioning holes 33 and has a bottom 41 on a top of the projection light 13. The transparent bottle 40 is filled with a filler 43 having two kinds of immiscible liquid; the filler 43 includes liquid, paraffin having a higher density than the liquid, or mineral oil. However, it is a prior art and thus will not be described in details here. In an applicable embodiment, the transparent bottle 40 further includes a plurality of paillettes 44 as shown in FIGS. 2 to 8.
The two pieces of reflection mirrors 50a, 50b fixed on the support bracket 30 are located at a rear side of the transparent bottle 40, and have reflection surfaces facing forward and a center serving as a reference to define the two pieces of symmetrical reflection mirrors 50a, 50b, and both sides of the two pieces of reflection mirrors 50a, 50b are inclined forward to form an angle θ being not parallel with the film-coated glass 20 with 180° angle, which the angle θ is between 160° to 175°. After the filler 43 of the transparent bottle 40 is reflected repeatedly and cumulatively by the two pieces of reflection mirrors 50a, 50b, the vision window 11 shows shapes being in an inward serial arrangement in the middle and unlimited extension and diffusion on both sides; and a cover plate 60 is arranged at the back opening of the frame 10.
