Self-powered illumination device
First Claim
1. A self powered illumination device for floating on a surface of a body of water having a water-air interface, said device including a power source and an illumination source contained within a buoyant body, the buoyant body having:
- a) an undersurface portion and a protruding, light transmitting, lower surface for projecting light into a body of water when the illumination device is floated in an upright orientation on the surface of such body of waterb) a dome having faceted surfaces surrounding the light source, the faceted surfaces surrounding the light source being angled to redirect a portion of light emitted downwardly towards a more upwardly direction wherein;
the source of illumination is of a dimension and is positioned at a distance below the undersurface portion to provide that a greater portion of light emitted therefrom is directed for emission in the lateral direction rather than the downward direction and a portion of the downwardly emitted light is directed at an upward angle for reflection off of the water-air interface and then outwardly and laterally from the fight source.

Abstract
A self-powered illumination device includes an illumination source protruding from its lower surface for projecting light into a body of water to provide light that is emitted preferentially outwardly to illuminate the sides of a pool. Light emitted with an upward angle of inclination strikes the underside surface of the water-air interface surrounding the device and is reflected outwardly and laterally away the from the light source after striking such underside surface. Preferably, the illumination source has a length that extends downwardly that is commensurate or greater than its width and may be in the form of a fluorescent tube. The illumination device is fully self righting when inverted on the surface of a body of water.
