Abstract
A resistive bubble lamp structure is disclosed and claimed, which comprises a vacuum glass tube containing liquid CH2Cl2 with a low boiling point and a circuit mounted at the bottom end of the vacuum glass tube and externally connected to a power supply. The circuit comprises at least one heat-emitting resistive element, which closely surrounds the bottom end of the vacuum glass tube and provides heat to the vacuum glass tube to heat the liquid CH2Cl2 to its boiling point and generate bubbles therein. The circuit further comprises at least one LED to provide light emissions in various colors at the bottom of the vacuum glass tube. The circuit can be further fitted with an integrated circuit control board to control the light emission of the at least one LED.

A resistive bubble lamp structure, comprising:
- a vacuum glass tube containing liquid CH2Cl2 with a low boiling point, and
- a circuit mounted at the bottom end of the vacuum glass tube and externally connected to a power supply, said circuit comprising
- at least one heat-emitting resistive element, which closely surrounds the bottom end of the vacuum glass tube and, when electrical current is passed through the circuit, provides heat to the vacuum glass tube to heat the liquid CH2Cl2 to its boiling point and generate bubbles therein, and
- at least two light-emitting diodes (LED), which provide light emission in various colors when electrical current is passed through the circuit.
