Abstract
A fluidized bed lamp which provides a pleasing visual and audible display. A bed of particles is contained within an outside tube and supported by a distribution plate. A liquid is pumped through the bed of particles, causing the bed to be in a state of fluidization. Fluidization is characterized by the bed behaving as a suspension with the particles moving about in a chaotic manner. The liquid is returned to the pump with a downcomer tube. The fluidized bed of particles is illuminated with a light fixture contained within the downcomer tube or by lights on the top or bottom of the lamp assembly.
