Patent ID: 8911100

Claim:
A self-generating lighting shower head, comprising: A top hood with a through hole; An upper holder held inside said top hood and comprising a joint part at top and a water bearing space at bottom: said joint part which protrudes from said through hole on said top hood and links an outlet hose of a bathroom comprises a clearance hole leading to said water bearing space to which water flows from said outlet hose is conveyed; An inlet header held in said upper holder's water bearing space and comprising (a) a water feeding space centrally and downward and (b) a number of water inlets arranged circumferentially and leading to said water feeding space, both of which allow ater originally held in said upper holder's water bearing space to pass through and run downward; A revolving part comprising a core hole centrally and a number of radial rotary vanes circumferentially which are held in said water feeding space of said inlet header and rotate under rush of water flows; A lower holder, a component slightly smaller than said water bearing space of said upper holder, comprising (a) an assembly-related core hole at top which is located under said water bearing space of said upper holder for development of an appropriate gap, (b) a watertight cavity under said core hole, and a number of discharge orifices on circumference of said watertight cavity through which downward water flows out of said inlet header's water feeding space pass through said gap between said lower holder and said upper holder and run outward; An electric module provided with a spindle, a protective shell, a printed circuit board and a number of luminous components on said printed circuit board and held in said watertight cavity of said lower holder: said spindle protruding from said watertight cavity is pivoted to said core hole of said revolving part and synchronously driven by said revolving part for output of electric energy transformed from dynamic energy because of rush of external water flows; A shade unit comprising a shade, a first washer, and a bolt-on disc, all of which are assembled with female threads on said bolt-on disc screwed onto male threads at a lower end of said lower holder; A shower head disc unit installed at said upper holder's bottom and comprising a center hole aligning said lower holder's watertight cavity, separating luminous components from water, and surrounded by a plurality of nozzles through which water flows passing through said gap between said lower holder and said upper holder are sprayed downward.
