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.

A water-powered light comprising, in combination, a housing having a pair of end portions, one of which is substantially closed and the other of which is substantially open, a stationary shaft means having one end cantilever supported at the closed end portion of the housing, the shaft means projecting therefrom substantially axially of the housing and having a free end within the housing, a rotor assembly journaled on the shaft means, the rotor assembly including an impeller and further including a rotor member, passageway means within the closed end portion of the housing for directing water flow to the impeller, thereby driving the rotor assembly, permanent magnet means carried on the rotor member, a stator assembly mounted on the free end of the shaft means, the stator assembly being disposed axially forwardly of the rotor assembly and having an annular clearance relative to the housing, the stator assembly including a stator housing having first and second stator members secured therein and further having a coil nested between the stator members, a lamp assembly in the housing forwardly of the stator assembly and electrically connected thereto, and lens means mounted on the open end portion of the housing forwardly of the lamp assembly, the lens means having aperture means formed therein, whereby the water may flow out of the rotor assembly, through the annular clearance between the stator assembly and the housing, and out of the aperture means in the lens means.
