Portable self contained light generating device powered by a flow of falling granular material

A portable self contained light generating device powered by a flow of falling granular material turning a paddle wheel, the light device comprising:

• a support means having two opposing substantially flat base members held in a distally spaced relationship by a plurality of support rods which span between the bases and are secured to the bases, the bases and support rods defining an interior region, the bases configured to support the light generating device in an upright position on the base when the base is resting on a substantially horizontal surface;
• first and second chambers for holding granular material, the chambers contained within the interior region of the support means;
• granular material received into and filling a portion of at least one chamber;
• a neck having a passage therethrough providing communication between the first and second chambers through which the granular material can flow;
• a paddle wheel rotatably mounted in the passage of the neck to intercept granular material flowing through the neck between the first and second chambers;
• a baffle secured to the interior of the neck, restricting the flow of granular material to one half of the paddle wheel;
• a generator connected to a shaft of the paddle wheel, wherein granular material flowing through the neck between the chambers urges that paddle wheel to rotate thereby operating the generator to produce an electric potential;
• one or more light emitting diodes (LEDs) secured to the support means, the light emitting diodes provided on at least one side of the support means;
• a multi-position power switch secured to the support means, the power switch interposed in at least one electrical circuit between the generator and the light emitting diodes,
• wherein the granular material flows from one chamber to the other chamber under the influence of gravity, the flowing granular material causing the paddle wheel to rotate operating the generator, the generator providing electric power to operate at least some of the light emitting diodes.
