Abstract
A method for making a light-emitting diode (LED) emitter module includes providing a substrate and providing two or more groups of LED dies disposed on the substrate. Each group has one or more LED dies, and each of the LED dies is coupled to an electrical contact and electrical paths are configured for feeding separate electrical currents to the groups of LED dies. The method also includes determining information associating a plurality output light colors with a corresponding plurality of combinations of electrical currents, each combination specifying a plurality of electrical current values, each electrical current value being associated with an LED die from one of the two or more groups of LED dies. The method also includes storing the information in the memory device, and providing a circuit for accessing the information in a memory device.
