Abstract: A lamp illuminates a waterfall from behind as a liquid cascades down the outside of a housing into a basin. From the basin, the liquid flows through a cavity in the housing, behind a body and through a pump, through an outflow line, through a cap with filter, and into a liquid retainer at the top of the body. The liquid retainer overflows, allowing the liquid to cascade down the outside of the body and back into the basin for recirculation. The enclosure comprises alternating opaque and translucent bands. A light source within the cavity behind the enclosure illuminates an inside surface of the body with the translucent bands transmitting light through the cascading liquid, producing an appealing visual effect.
