    Abstract: A substrate for an LED emitter includes a body with a recess region formed therein. Bonding pads are disposed within the recess region, including LED bonding pads for LEDs and supporting chip bonding pads for one or more semiconductor chips that provide supporting circuitry (e.g., driver and/or controller circuitry) to support operation of the LEDs. External electrical contacts can be disposed outside the recess region. Electrical paths, disposed at least partially within the body of the substrate, connect the external electrical contacts to a first subset of the supporting chip bonding pads and connect a second subset of the supporting chip bonding pads to the plurality of LED bonding pads such that one or more supporting chips connected to the controller pads can be operated to deliver different operating currents to different ones of the LEDs.

    Abstract: An LED-based lamp can be made to have a form factor compatible with fixtures designed for MR16 lamps. Such a lamp can have a housing that provides an external electrical connection. Inside the housing is disposed a single emitter structure having a substrate with multiple light-emitting diodes (LEDs) arranged thereon. Different LEDs produce light of different colors (or color temperatures). For example, at least one LED can produce a warm white light, while at least one other LED produces a cool white light and at least one other LED produces a red light. A total-internal-reflection (TIR) lens is positioned to collect light emitted from the single emitter structure and adapted to mix the light from the LEDs to produce a uniform white light. A diffusive coating is applied to a front face of the TIR lens for further color mixing.

    Abstract: An emitter for an LED-based lighting device has multiple groups of LEDs that are independently addressable, allowing the emitter to be tuned to a desired color bin (e.g., a specific white color) by adjusting the relative current supplied to different groups. The LED dies for the groups and a phosphor chip for each LED die are individually selected such that each LED-die/phosphor-chip combination produces light in a desired source region associated with the group to which the LED belongs. Robotic pick-and-place systems can be used to automate assembly of the emitters by selecting LED dies from a bin based on based on spectral characteristics and phosphor chips from a number of distinct phosphor chip types.
