| Title: |
Control System for Liquid Motion Lamp |
| Abstract: |
A control system for a liquid motion lamp maintains the proper temperature
of liquids within the lamp to provide desired motion within the lamp, and
reduces sensitivity to ambient temperature. The lamp preferably includes
two heating elements, a first element for initial heating, such as a heat
blanket, resistive glass coating, or a submerged ring, and a second
heating element generally providing both heat and lighting. A sensor
measures the temperature of the liquid inside the lamp and the control
system controls the heat sources to maintain the temperature within
operating limits.
