Abstract
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. A set of corresponding light-emitting diodes together with the shunt couplings define a cell. The branches along with the shunts are coupled in a specifiable lattice arrangement.
