The principle of the liquid flow lamp is to use the heat provided by the bulb to make the liquid of the first substance in the container move relative to each other, and the second substance floating in the liquid floats and sinks with the relatively moving liquid, and under the projection of the bulb's illumination, it makes it float from time to time. Many floating objects that rise and sink from time to time can produce gorgeous and vivid visual effects. Liquid flow lamps use light bulbs to provide the heat required for liquid movement, and also provide the projected illumination required for vision.

And the bottom of this cooling frame 45 is provided with a nut 46 can connect a fixed pipe 22, the lower end of this fixed pipe 22 communicates with this base body 10, and utilizes another nut 47 to be locked on this base body 10 (Fig. 5 shown).

Please refer to Figures 3 to 5, which are an exploded perspective view and an assembled cross-sectional view of the light-heat separation structure 40 of the present invention. The mechanism conversion of the current driver 41, its rear end output then becomes a constant DC power supply 13; in this embodiment, it is two groups of resistors 43, and its pins 431 have a considerable height, when it is soldered on the substrate 42, and with the DC After the power supply 13 is connected and energized, the resistor 43 will generate high heat. Since the resistor 43 is placed under the transparent bottle of the liquid flow lamp 30 and has a small distance G (as shown in FIG. 5 ), the heat will form a Heat source: Since the heating surface of the resistor 43 is far away from the substrate 42, the substrate 42 and the LED bulb 44 are kept at a distance from the resistor 43, so they will not be subjected to heat conduction.

The utility model is a structure in which the light source of the LED light bulb 44 and the radiated heat of the resistor 43 are separated from light and heat. When applied to the liquid flow lamp device, the LED bulb 44 will not be affected by the heat of the resistor 43, and the heat emitted by the LED bulb 44 will also be Diverge by means of the heat sink 45, therefore, the LED bulb will achieve a longer service life; and the utility model uses the embedded section 25 of the joint sleeve 23 to cooperate with the upper chamber 53 of the upper fixing seat 52, so that the The installation and disassembly of the transparent bottle of the liquid flow lamp 30 becomes convenient and easy; in addition, the utility model combines the liquid flow lamp 30 with the lighting device of the lighting bulb 55, so that the liquid flow lamp for viewing can also have the function of lighting .

The color of the light source can also make the onion slices fully exert the best reflection effect of the silver-plated onion slices themselves under white light.

With the help of the above technical means, the utility model constitutes the "heat source" and "light source" functions as independent circuits, and keeps the resistor 43 that generates the heat source and the LED bulb 44 that generates the light source at an appropriate height distance to form a A light and heat generation structure is separated, but the space is in a three-dimensional form with different heights. In addition to not occupying space, it also has a complementary effect, so that the "light source" and "heat source" required by the liquid flow lamp can be achieved separately. The best benefit distribution has the effect of saving electricity and prolonging the service life of LED bulbs.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form.
