1. An assembly for an illumination device that incorporates a light fixture, the assembly comprising:

  • a printed circuit board having (i) top and bottom opposed, substantially rectangular surfaces, and (ii) first and second shorter-length sides (a) having lengths less than lengths of the remaining two sides and (b) spanning the top and bottom surfaces;

    first and second electrically conductive bumps on opposing ends for (a) use as electrical input and output and (b) direct physical mounting in and direct electrical connection with the light fixture without wires attached to the first and second electrically conductive bumps, wherein (i) the first electrically conductive bump is disposed on the first shorter-length side, (ii) the second electrically conductive bump is disposed on the second shorter-length side, and (iii) the first and second electrically conductive bumps protrude from the first and second shorter-length sides (a) in opposite directions, and (b) in directions substantially parallel to surface normals of the first and second shorter-length sides;

    at least one solid-state light emitter electrically connected to the printed circuit board; and

    disposed on the printed circuit board, a driving circuit in electrical communication with the electrically conductive bumps and the at least one solid-state light emitter for providing suitable current to the at least one solid-state light emitter.
