Patent ID: 7380961

Claim:
A light source assembly comprising: a plurality of electrically connected light sources; and a connective conductor structure extending in a direction of arrangement of the light sources to join the light sources, wherein the connective conductor structure is formed by cutting off parts of a substantially plate-like patterned conductor as required, the patterned conductor being provided with a prescribed pattern, wherein each of the light sources has a pair of terminals; wherein the patterned conductor is of a longitudinal tape-like shape, and comprises: a plurality of light source attachment portions arranged in a longitudinal direction for electrical connection with the light sources; an interconnection path for connecting the light source attachment portions in the longitudinal direction; a pair of trunk paths disposed on either side of the patterned conductor so as to interpose the interconnection patch and the light source attachment portions therebetween and extending in the longitudinal direction; and a plurality of branch paths widthwise connecting the trunk paths to the interconnection path; each of the light source attachment portions has a pair of terminal connection parts corresponding to the pair of terminals of the light sources, and the interconnection patch comprises a plurality of connection paths each connecting the terminal connection parts contained in adjoining light source attachment portions such that each terminal connection part of each light source attachment portion is connected to one of the terminal connection part of an adjoining light source attachment portion by an associated connection path; wherein the connective conductor structure is formed by cutting off a portion of the branch paths, interconnection patch or trunk patch of the patterned conductor to select one of series, parallel and series-parallel connections of the light sources.
