Heater-plate-affixed light-emitting diode lava lamp

Abstract

The LED lava lamp comprises a base defining a chamber 4 and a transparent lava lamp bottle 2 located on the base. A control device 5 located in the chamber includes a circuit board 51 at the bottom of the chamber. A heat-generating module 53 is connected to the circuit board and comprises a heater plate including an adhesive layer, an insulating layer tightly adhered to the bottle, and a heating layer wrapped around the insulating layer by the wrapping layer. The control device may further comprise a lighting module 52 to illuminate the bottle, optionally via a hole or area of transparent film in a middle of the heater plate. The base may comprise a cup body defining the chamber and located at a top of a holder on a base body, optionally circular and provided with an anti-slip sheet. The cup body may comprise a hole 13a with an inductive probe for receiving control signals.
