Patent ID: 8901829

Claim:
A solid state lighting apparatus comprising: a circuit comprising a plurality of light emitting devices wherein the solid state light emitting devices are connected in series to form a string including an anode terminal at a first end of the string and a cathode terminal at a second end of the string; a first configurable shunt directly coupled between a terminal of a first light emitting device in the string and at least one of the cathode or anode terminal of the string and configured to bypass at least sonic current around the first light emitting device; a second configurable shunt directly coupled between a terminal of a second light emitting device and a same end terminal of the string as the first configurable shunt and configured to bypass at least some current around the first light emitting device and the second light emitting device, wherein the second light emitting device emits light of a different color than the first light emitting device; and a thermistor, tunable resistor and/or variable resistor coupled in parallel with the first and second configurable shunts, wherein the thermistor, tunable resistor and/or variable resistor is different than the first and second configurable shunts.
