Abstract

A solar charging lamp is set forth wherein a twelve-volt direct current lamp is illuminated by means of a wet-cell battery recharged by solar cells integrally secured to said lamp. An optional cord for attachment to an automotive cigarette lighter is available to enable charging of an automotive battery by means of the solar cells or alternatively, illuminate the lamp during continuous overcast conditions from an auxiliary battery source, as in an automoile. A photo-electric eye is operative to automatically illuminate the light in evening hours with an optional infra-red sensor operative to activate by operation in response to physical movement proximate the infra-red sensor.

Claims

1. A solar charging lamp post comprising,

a vertical housing means including a transparent globe protectively containing an illumination bulb therein secured to an upper terminal end of said housing means, and

photo-voltaic cell means for collecting and converting solar energy to direct current electrical energy, and

a direct current storage battery secured within a battery housing means operatively associated with said photo-voltaic cell means for accepting and storing said electrical energy from said photo-voltaic cell means, and

further housing means secured to said vertical housing means for storage of a length of electrical cord formed with an adaptor at one end thereof operatively associated with said photo-voltaic cell means for selective electrical association with an automobile for providing electrical energy to a storage battery within said automobile, and

wherein said illumination bulb is a direct current bulb of a wattage range of ten to twenty watts, and

wherein said photo-voltaic cell means are secured to brackets on said vertical housing means wherein said vertical means is cylindrical and said bracket means include a plurality of brackets diametrically opposed proximate said upper terminal end of said vertical housing means, and

wherein said globe is of polyhedral configuration formed with an upper surface wherein said upper surface has positioned thereon said photo-voltaic cell, and

wherein said battery housing means is secured to a lower terminal end of said vertical housing means for providing stability to the solar charging lamp post, and

wherein a photo-cell is operatively associated with said bulb for enabling illumination of said bulb during periods of darkness, and

wherein infra-red movement sensor is operatively associated with said photo-electric cell further including switch means for disengaging said cell and providing switching of said bulb through said infra-red movement sensor for illuminating said bulb upon sensing movement proximate said sensor.
