US 5,362,267 A · Solar powered buoy

Abstract

A solar powered lantern device is visible even without a beacon under reflected light and can be easily color coded to conform to the marking requirements of a new location. The lantern device includes a housing, a lighting element supported by a luminescent internal frame, a photovoltaic power supply, and an omnidirectional reflector. In particularly preferred forms, the lantern device is a buoy having a modular housing with interchangeable colored elements. A lighting element is centrally supported inside the housing by a luminescent frame, which serves to reflect light from approaching craft when the lighting element fails. The device may also be mounted atop a pole. In preferred forms the frame is hollow and forms a conduit for electrical conductors from the power supply to the lighting element. A pair of conical reflectors is positioned within the housing to reflect the beacon light omnidirectionally.

Dependent claims

A self-contained floating buoy with a solar powered lantern, comprising:

(a) a housing, having a bottom portion including a flotation assembly in a lowermost section and an uppermost transparent lens section, and a top portion;
(b) a lighting element for emitting a signal light;
(c) a frame supporting said lighting element inside said housing in spaced relationship to said top portion and said lowermost section of said bottom portion;
(d) a photovoltaic power supply including a solar panel, and a storage battery;
(e) electrical conductor means coupling said power supply with said lighting element;
and
(f) reflecting means coupled with said housing for omnidirectional reflecting of said signal light, said reflecting means including a pair of spaced, generally parabolic reflector members, one positioned above and one positioned below said signal light, one of said parabolic reflectors being coupled with said top portion of said housing and the other of said reflector members being attached to said lowermost section of said bottom housing portion.
