FIGS. 1-6 , the structure of the present invention mainly comprises abase frame 10, amounting seat 20, aliquid motion lamp 30 and anisolated heating device 40. - The
base frame 10 has anAC supply cord 12 arranged through. Themounting seat 20 is disposed on thebase frame 10 with ahollow section 21 arranged therein and at least oneheat dissipating hole 211 arranged on the periphery thereof. Theliquid motion lamp 30 is a transparent bottle disposed on themounting seat 20 withliquids 31 and a plurality ofglitters 32 therein. Theisolated heating device 40 is disposed in thehollow section 21 of themounting seat 20 and comprises a constantcurrent driver 41, at least onesubstrate 42, acement resistor 43, aLED bulb 44 and aheat dissipating rack 45. The constantcurrent driver 41 is connected to an ACpower supply cord 12 for converting AC power intoDC power supply 13. - In this embodiment, the
substrate 42 may include afirst substrate 42a and asecond substrate 42b. Thefirst substrate 42a is electrically connected to anAC power supply 14 and has aspace 421 in the middle; thecement resistor 43 is connected to thefirst substrate 42a with a pair of connectingpins 431 from above. TheLED bulb 44 is disposed on thesecond substrate 42b which combines with thefirst substrate 42a from below, exposing itself in the space of thefirst substrate 42a, thus forming a combinedcomposite module 42A with isolated circuits of lights and heat as thecement resistor 43, the source of heat energy, being arranged above theLED bulb 44, the source of lights, in a pre-determined distance. - In this embodiment, the
heat dissipating rack 45 is disposed in themounting seat 20 with thecomposite module 42A with isolated circuits disposed thereon; and the bottom of thecomposite module 42A can be fixed on theheat dissipating rack 45 with conductingadhesive 422. - Furthermore, the
heat dissipating rack 45 is a hollow case for the constantcurrent driver 41 to be disposed therein, and the bottom thereof has anut 46 connecting afixing tube 22 with the lower end of thefixing tube 22 penetrating through thebase frame 10 and being fixed on thebase frame 10 by anut 47. TheAC supply cord 12 is separately connected to the constantcurrent driver 41 and thefirst substrate 42a by passing through thefixing tube 22 from thebase frame 10 to theheat dissipating rack 45; and the first andsecond substrate heat dissipating rack 45 by ascrew 423. - In an applicable embodiment, the present invention may include an assembling
element 23 which has ahollow space 24 therein and anengaging section 25 at the lower end thereof, to fixedly engage in thehollow section 21 of themounting seat 20 so that the assemblingelement 23 would be fixedly engaging themounting seat 20; and theliquid motion lamp 30 has an insertingsection 33 to be inserted into thehollow space 24 in the assemblingelement 23 to fix theliquid motion lamp 30 on the assemblingelement 23. - In an applicable embodiment illustrated in

Theliquid motion lamp 30 is therefore located vertically along the axis Y-Y. Since theupper fixing seat 52 has theengaging space 53 and the assemblingelement 23 has theengaging section 25, theliquid motion lamp 30 is able to displace together with the assemblingelement 23, making it easily engaged and disengaged. The present invention further includes abulb holder 54 disposed on theupper fixing seat 52 connecting to theAC supply cord 12 through the hollow supportingbracket 51.FIG. 2 illustrates the present invention in an applicable embodiment, including abulb 55 disposed in thebulb holder 54 and alampshade 56 disposed above thebulb holder 54, so as to form a device combining the liquid motion lamp and a lighting bulb.

With the distance from thefirst substrate 42a to thecement resistors 43, thefirst substrate 42a would not be affected by the heat. TheLED bulb 44 is disposed on thesecond substrate 42b, fixed on theheat dissipating rack 45 by conducting adhesive 422 and connected to the constantcurrent driver 41 providing constantDC power supply 13. When being electrified, theLED bulb 44 would project lights to theliquid motion lamp 30 and the heat produced by theLED bulb 44 would be dissipated by theheat dissipating rack 45. Thus, the structure of separated sources of lights and heat is completed. - Whereby the
cement resistor 43 would produce heat when theAC supply cord 12 is electrified, causing the flowing of theliquids 31 in theliquid motion lamp 30, and theLED bulb 44 would project lights when receiving the DC power from the constantcurrent driver 41 and create a vivid visual effect when the lights are reflected by the plurality ofglitters 32 in the liquid motion lamp. -

The forward bias and the current of the DC power are in relation of index numbers; therefore, a small change in the voltages would hugely affect the currents and thus the lighting of theLED bulb 44 that obtains power from the DC power. TheLED bulb 44 may be permanently damaged with serious effects. The function of the drivingcircuit 412 is to convert the power supply into a specific voltages and ampere of currents for theLED bulb 44; consequently the output terminal of the drivingcircuit 412 is a constant current supply that can adjust the voltages with theLED bulb 44. TheDC power supply 13 in the figure is the constant current supply for theLED bulb 44 to emit lights and project the lights to theliquid motion lamp 30. - Also, in this preferred embodiment, the present invention has the
cement resistors 43 to produce heat. A cement resistor is formed by having a wire-wound resistor put inside a square case and filled with special cement with non-flammability and heat resistance. Such resistor has larger resistance that requires higher currents to pass through; therefore, as shown in the figure, theAC power supply 14 is directly connected to theAC supply cord 12. The rectifyingcircuit 411 includes a bridge rectifier D1 and related electrical components, and the drivingcircuit 412 includes a LED constant current IC U1 connected to related components. The LED constant current IC U1 has protection circuits for overload and over heat with a small volume, and therefore is suitable for the present invention. Such device is commonly seen in the markets and therefore is not the primary patented object. - The present invention applied the structure of separated circuits to the
