Abstract
Abstract A hydroelectric illumination source powered by a small alternator designed to provide underwater illumination or in-stream illumination such as for a shower head, fountain, or swimming pool. The water pressure from a direct line or recirculation pump is used to drive a small armature that produces an alternating current which illuminates a bulb operatively connected thereto.

Claim 1
Independent Claim
212 words
A hydro-light, comprising a main body having a substantially longitudinal axis and further having forward and rearward end portions, a pair of support webs within the body and constituting first and second support webs axially spaced relative to one another, an electrical generator including a stator mounted within the first and second support webs, the generator further including an armature within the stator, a vaned wheel in the main body rearwardly of the generator and arranged for driving the armature, means for accommodating water flow into the rearward end portion of the body, against the vaned wheel and axially of the body, and through the first and second support webs between the generator and the body, a third support web mounted substantially on the forward end portion of the body, the third support web including a reflector portion and having an opening therein for flow of water therethrough, a light bulb mounted in a socket on the reflector and connected to the generator, a substantially-cylindrical elongated lens cap mounted on the forward end portion of the body, and the lens cap having a substantially flat end wall provided with a plurality of apertures for flow of water therethrough, thereby providing a substantially fine spray illuminated by the light radiating from the bulb.
