Abstract

A light engine includes a first plurality of diodes coupled in series. The first plurality of diodes includes a first anode end and a first cathode end. A second plurality of diodes is coupled in series. The second plurality of diodes includes a second anode end and a second cathode end. A first terminal is electrically coupled to the first cathode end and said second anode end to form a first node. The second terminal is coupled to said first anode end. A third plurality of diodes is coupled in series. The second plurality of diodes includes a third anode end and a third cathode end. The third terminal is coupled to the third cathode end. A fourth terminal is electrically coupled to the second cathode end and the third anode end to form a first node.
