Claim:
1. A substrate for an LED emitter, the substrate comprising: a body with a recess region formed therein; a plurality of bonding pads disposed within the recess region, the plurality of bonding pads including a plurality of LED bonding pads and a plurality of supporting chip bonding pads; a plurality of external electrical contacts disposed outside the recess region; and a plurality of electrical paths disposed at least partially within the body of the substrate, the electrical paths connecting the external electrical contacts to a first subset of the supporting chip bonding pads and connecting a second subset of the supporting chip bonding pads to the plurality of LED bonding pads such that a controller/driver chip bonded to the supporting chip bonding pads is operable to deliver different operating currents to different ones of the LEDs in response to a control signal received via one of the external electrical contacts.
