Abstract: An emitter for an LED-based lighting device can incorporate “flip-chip” LEDs, in which all electrical contacts are disposed on the bottom surface of the chip. The emitter base can be a multilayer high-temperature cofired ceramic (HTCC) substrate, with metal traces formed between the layers and vias through the layers to join traces in different layers, thereby providing electrical connectivity to each LED. The paths can be arranged such that current can be supplied independently to different subsets of the LEDs. The top layer of the emitter base is fabricated with exposed vias at the top surface. Metal pads are then printed onto the exposed vias on the top surface, and flip-chip LEDs are bonded to the metal pads, e.g., using solder.

Abstract: LED-based light source modules can incorporate color tunability and brightness control, allowing a user to select a desired color temperature and/or brightness and to change either or both dynamically. An emitter can include multiple independently addressable groups of LEDs, each emitting light of a different color. By controlling the relative operating current provided to each group, a desired color temperature can be achieved, and by controlling the absolute operating currents, the brightness of the output light can be controlled. Pulse width modulation (PWM) can be used to control the relative and absolute operating currents. Smooth, gradual transitions between brightness and/or color temperature settings in response to changes can be provided.

Abstract: A color-tunable LED emitter with high CRI can be made by mounting multiple LED chips onto a ceramic substrate that has been patterned with metal contacts and paths so as to connect the LED chips into multiple independently addressable LED groups. Each LED group can produce light of a different color, allowing the color of the emitter to be tuned by adjusting the relative amount of operating current supplied to each LED group. At least some of the LED groups include LEDs coated with a broad spectrum phosphor that can reduce the sharpness of spectral peaks, thereby improving CRI and particular components of CRI, such as R9.
