Abstract:
1. A solar powered light and alarm system comprising: a unitary semi-ellipsoidal housing having a planar back wall conjoined to an ellipsoidal front wall, said front wall having an aperture there through and a transparent lens seated within said aperture, a first surface area of said lens comprising a Fresnel surface area for light gathering and a second surface area of said lens comprising a smooth surface area for light transmission, said housing with lens defining a fully-enclosed hollow interior; a power distribution circuit, said power distribution circuit further comprising, a passive infrared (PIR) sensor seated in the interior of said housing behind the Fresnel surface area of said lens, said PIR sensor identifying changes in ambient infrared radiation indicative of movement; a circuit controller within the interior of said housing electrically connected to said PIR sensor and to said power distribution circuit; a light source seated within the interior of said housing behind the smooth surface area of said lens and electrically connected to said circuit controller; a speaker and speaker driver within said housing electrically connected to said circuit controller via a second switch for providing an audible alarm; whereby said circuit controller activates said light source and said audible alarm on receipt of a signal from said PIR sensor indicating that motion has been sensed.
