Single chip LED as compact color variable light source

A color variable light-emitting device, comprising:

• an array of a plurality of light-emitting diodes formed on a resistive substrate so that said plurality of light-emitting diodes share said resistive substrate, said array comprising at least first, second and third sets including at least a first set of at least one light-emitting diode arranged to provide light of a first color, a second set of at least one light-emitting diode arranged to provide light of a second color and a third set of at least one light-emitting diode arranged to provide light of a third color;
• and
• a sub-mount on which resistive substrate including said array is arranged, said sub-mount being provided with a circuitry, to which said array of the plurality of light-emitting diodes is connected, wherein each light-emitting diode in said array has a separate connection to said circuitry;
• wherein at least one set of said at least first, second and third sets comprises at least two light-emitting diodes, interconnected in series via said circuitry;
• and
• wherein said circuitry comprises external connectors to independently address one set of said at least first, second and third sets.
