Since the sixties of the last century, lava lamps have become a common device in the worldwide university student dormitories and teenage children bedrooms. Lava lamps have been deeply implanted into the popular culture of the United States and many other countries.

With reference to FIG. 1, US Patent No. 3,570,156 discloses a lava lamp display device 60 comprising: a glass vessel 61 having a bottom 62 arranged in a hollow conical metallic seating 63 and located on an electric light bulb 64. Moreover, the glass vessel 61 has two immiscible substances. For example, the first substance is liquid 65 and the second substance is paraffin 66 which has a higher density than the liquid 65 at room temperature and a lower density than the liquid 65 after heating. After the electric light bulb 64 is turned on, the paraffin 66 in the bottom 62 of the glass vessel 61 is heated and flows in the liquid 65. At the same time, the electric light bulb 64 projects the light in the glass vessel 61, forming a lighting effect and becoming decorations at home and office. The solid paraffin requires a long time for heating to melt while suspended in the liquid. Therefore, in recent practice, the second substance is set to be a solid or liquid, and the specific gravity value thereof must be similar to the liquid of the first substance such that the lava lamp has it a dynamic function via the short heating time. Such improvement and the aforesaid lava lamp structure are so called liquid motion lamp.

The principle of the liquid motion lamp is to provide a heat from a bulb for the liquid of first substance within the container to produce convection for the second floating substance in the liquid moving up and down with the liquid. Under the illumination of the projection light, the floating objects float and sink, producing brilliant and vivid visuals.

However, the transparent container without stable installation structure is easily overturned and broken, which allows the internal liquid to harm human body. Therefore, the present invention is provided for enhancing the stability and safety of the liquid motion holder and the convenience of the installing and removing the transparent bottle.

It is the first primary object of the present invention to provide a liquid motion lamp holder combined lighting to combine lighting and decoration functions.

It is the second object of the present invention to provide stable liquid motion lamp holder to avoid overturning and falling apart the transparent container which is able to harm human body by flowing-out liquid of the transparent container.

It is the last object of the present invention to provide a liquid motion lamp transparent bottle and a bulb which are easy to be installed and removed for increasing the convenience and security effects.

In order to achieve the above objects, the liquid motion lamp holder improvement comprises: a holder having a base on a bottom thereof; a first mounted seat having a bottom mounted on the base and a first containing room with an upward opening at an inner periphery thereof; a second mounted seat arranged on a top of the holder and having a second containing room with a downward opening at an inner periphery thereof and the second containing room having a containing height of at least 5cm; a support bracket having an end connecting to a lower end of the holder and another end connecting to the second mounted seat for centers of the first mounted seat and second mounted seat to be vertically located on an axis of the base, being in an up-down corresponding state; a projecting light source including a first lamp seat mounted in the first containing room of the first mounted seat and a bulb mounted on the first lamp seat; a lighting lamp including a second lamp seat mounted on the support bracket and a lighting bulb mounted on the second lamp seat; and a transparent bottle arranged between the first mounted seat and second mounted seat and having two immiscible substances therein, an upper end for moving upward to the second containing room to a predetermined height and a lower end for moving downward to the first containing room so that the transparent bottle is securely positioned between the second containing room and first containing room.

Whereby the transparent bottle turns into liquid motion lamp visual effect through the projecting light source and required lighting is available through the lighting bulb, and the design of the second containing room allows an end of the transparent bottle to be moved in the containing height along the vertical axis of the base up and down for the transparent bottle to be easily installed and removed between the first mounted seat and second mounted seat.
