ABSTRACT:
A water-powered light for decorative or utilitarian purposes has a stator assembly mounted on the forward end of a fixed shaft within the housing. The shaft is cantilever supported at one end of the housing and projects forwardly therefrom. A rotor assembly is journaled on an intermediate portion of the shaft. The rotor assembly is axially separated from, but in close proximity to, the stator assembly on the end of the fixed shaft; and the rotor assembly carries permanent magnet means for cooperation with a coil in the stator assembly. A lamp assembly is mounted on the stator assembly forwardly thereof, and a lens cap is mounted on the housing forwardly of the lamp assembly. Water under pressure enters into the housing and passes through canals in a stationary disc member to impinge on an impeller nested within the disc member, the impeller being part of the rotor assembly. The water exits from the impeller, passes around the stator assembly and the lamp assembly and into the lens cap, and exits as a fine spray out of apertures formed in a flat end wall of the lens cap.
