Claim Text:
1. A liquid motion lamp with isolated heating device, comprising: a base frame having an AC supply cord arranged through; a mounting seat with a hollow section arranged therein disposed on the base frame; a transparent bottle disposed on the mounting seat as a liquid motion lamp with liquids and a plurality of glitters therein; an isolated heating device disposed in the mounting seat, comprising a constant current driver, at least one substrate, a cement resistor, and a LED bulb; the constant current driver including a rectifying circuit and a driving circuit with the front end thereof connected to a power supply cord for converting AC power into DC power; the cement resistor being disposed on the substrate and connected to the AC power to produce heat for the liquid motion lamp; the LED bulb being disposed on the substrate and connected to the constant current driver to obtain DC power and become the light source for the liquid motion lamp; the cement resistor being arranged in a pre-determined distance from the LED bulb so as to form an isolated heating device with an isolated circuit to be combined with a lighting circuit as a composite module; whereby the cement resistor would produce heat when the AC supply cord is electrified, causing the flowing of the liquids in the liquid motion lamp, and the LED bulb would project lights when receiving the DC power and create a vivid visual effect when the lights are reflected by the plurality of glitters in the liquid motion lamp.
