Patent ID: 7786499

Claim:
A replaceable through-hole LED light source comprising: an electrically conductive hollow outer lead frame having a threaded lower portion and an upper rim, said upper rim having a first annular portion of outer radius r 1 and a second annular portion of outer radius r 2 extending upwardly from the first annular portion, wherein r 2 is less than r 1 , said first annular portion and said second annular portion providing a step and a wall, respectively, to receive and support an optical housing; an electrically conductive inner lead frame, disposed within the outer lead frame, comprising a well in an upper portion of the inner lead frame and a shaft portion that extends axially through and out of the threaded lower portion of the outer lead frame; an insulation layer electrically isolating the inner and outer lead frames; at least one LED mounted within the well and electrically connected to the inner and outer lead frames; and an optical housing mounted upon the rim of the outer lead frame, said housing having a height and a curvature, said housing further having an annular base portion having a thickness equal to r 1 minus r 2 and an inner wall of radius r 2 adjacent said annular base portion to support said optical housing against said upper rim, said inner wall being configured to abut the upwardly extending second annular portion of the upper rim and said annular base portion being configured to abut the step of the upper rim.
