Patent ID: 8870408

Claim:
A portable light and light source adapter comprising: a light body having an open end for receiving a light source therein, the open end exposing a face including one or more raised bosses extending axially toward the open end in an asymmetric pattern and one or more electrical connections, said light body having a cavity for receiving a source of electrical power therein and optionally including an electrical switch for selectively energizing at least one of the electrical connections; a light source including an adapter base disposed in the open end of said light body, said adapter base having one or more raised bosses extending into the open end of said light body, said one or more raised bosses being in an asymmetric pattern that is complementary to the asymmetric pattern of the one or more raised bosses extending from the face of said light body, the one or more raised bosses extending from the face of said light body and the one or more raised bosses extending into the open end of said light body being complementary and asymmetric in that said adapter base cannot seat adjacent said face unless their complementary raised bosses are in a unique predetermined rotational relationship relative to each other for mating; said adapter base including one or more electrical connections that are located to mate with the one or more electrical connections on the exposed face only when said adapter base is seated adjacent said face in the unique predetermined rotational relationship for mating; whereby the orientation of said light source is uniquely predetermined relative to light body, said light source including a source of illumination electrically connected to the one or more electrical connections of said adapter base; and a retainer for retaining said light source disposed in the open end of said light body with said adapter base seated adjacent said face in the unique predetermined rotational relationship for mating.
