Abstract:
A circuit board comprising:a board having a front face and a rear face; an original LED having a body disposed on the front face of the board and two terminals, each of which extends from the LED body through a respective through-hole in the board to attain conductive continuity with a respective conductive trace on the rear face at a respective joint; the board comprising first and second through-openings separated by a bridge that comprises a platform on which the LED body is disposed and first and second approaches extending radially of a center of the platform; each through-opening spanning a respective arc that is substantially concentric with the center of the platform; a first of the traces comprising a first segment running along at least a portion of the margin of the arc spanned by the first through-opening and a second segment running along the first approach to one of the through-holes; a second of the traces comprising a first segment running along at least a portion of the margin of the arc spanned by the second through-opening and a second segment running along the second approach to another of the through-holes; each through-opening comprising notches that extend radially outward at opposite ends of the arc spanned by the respective through-opening such that the first approach is bounded by a first notch of each through-opening and the second approach is bounded by a second notch of each through-opening, wherein the first notches and the first approach collectively have a construction and arrangement that is asymmetric to that of the second notches and the second approach collectively about the center of the platform for enabling a replacement LED to be mounted in unique circumferential orientation relative to the center of the platform in a opening created by removing the bridge, including the original LED, from the circuit board and to have proper polarity connection to the respective traces.
