Patent ID: 7365991

Claim:
A printed circuit board for use in a lighting system, comprising: a board; a plurality of identical lighting emitting diode (LED) landing zones printed on the board, wherein: each of the identical LED landing zones includes two sets of LED contact pads, a first of the two sets of LED contact pads is configured to mate with a first contact configuration for a LED of a first structural type, a second of the two sets of LED contact pads is configured to mate with a second contact configuration for a LED of a second structural type different from the first structural type, the second contact configuration is different from the first contact configuration, within each identical LED landing zone: the first set of LED contact pads is arranged along a first axis, and the second set of LED contact pads is arranged along a second axis substantially orthogonal to the first axis, a portion of the board supporting the identical LED landing zones is circular; a line between two pads of the first set of LED contact pads is substantially non-tangential with respect to the circular portion of the board; and a line between two pads of the second set of LED contact pads is substantially tangential with respect to the circular portion of the board.
