<p>A lighting system comprising a plurality of light-emitting diodes and a current driver for driving current through a plurality of parallel disposed, electrically conductive branches, wherein the branches comprise at least one cell. In each cell, each branch has a light-emitting diode with an anode terminal and a cathode terminal. The anode terminal of each light-emitting diode is coupled to the cathode terminal of a light-emitting diode of an adjacent branch via a shunt. The shunt further comprises a light-emitting diode. In each cell, each light-emitting diode may have a different forward voltage characteristic, while still insuring that all of the light-emitting diodes in the arrangement have the same brightness. Upon failure of one light-emitting diode, the remaining light-emitting diodes in the lighting system are not extinguished.</p> |
