Claim Text:
1. A light-emitting diode (LED) emitter module, comprising: a substrate having a plurality of base layers of an electrically insulating material, a plurality of electrical contacts disposed on a top one of the base layer, and a plurality of electrical paths coupled to the electrical contacts, wherein at least a portion of the plurality of electrical paths is disposed between the base layers; first and second groups of LED dies disposed on the substrate, each group having one or more LED dies, each of the LED dies being coupled to an electrical contact, wherein the electrical paths are configured for feeding separate electrical currents to the groups of LED dies; a memory device containing information associating a plurality output light colors with a corresponding plurality of combinations of electrical currents, each combination specifying a first electric current for one of the first group of LED dies and a second electric current for one of the second group of LED dies; and a circuit for accessing the information in the memory device, wherein the substrate with the first and second groups of LED dies, the memory device, and the circuit are disposed on a same circuit board.
