    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 the memory device.

    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: Packages for LED-based light devices include interface structures that can facilitate heat transfer from the package to a heat sink. The package can include multiple LEDs mounted on a ceramic substrate that provides electrically conductive pathways between the LEDs and metal contact pads at a peripheral region of a top surface of the substrate. A bottom surface of the substrate can be patterned with a plate, such as a thick supporting plate, made of metal and/or other materials with high thermal conductivity, that can be attached to an external heat sink.

    Abstract: The color of an LED-based lamp can be tuned to a desired color or color temperature. The lamp can include two or more independently addressable groups of LEDs associated with different colors or color temperatures and a total-internal-reflection (TIR) color-mixing lens to produce light of a uniform color by mixing the light from the different groups of LEDs. The color of the output light is tuned by controllably dividing an input current among the groups of LEDs. Tuning can be performed once, e.g., during manufacture, and the lamp does not require active feedback components for maintaining color temperature.
