Abstract: Methods and apparatus for providing controllable power via an A.C. power source to LED-based lighting devices having an MR16 configuration.

Abstract: Methods and apparatus for providing and controlling power to loads including one or more LEDs. In one example, a controlled predetermined power is provided to a load without requiring any feedback information from the load (i.e., without monitoring a load voltage and/or load current). In another example, a “feed-forward” power driver for an LED-based light source combines the functionality of a DC-DC converter and a light source controller, and is configured to control the intensity of light generated by the light source based on modulating the average power delivered to the light source in a given time period, without monitoring and/or regulating the voltage or current provided to the light source. In various examples, significantly streamlined circuits having fewer components, higher overall power efficiencies, and smaller space requirements are realized.

Abstract: Power factor correction control methods and apparatus based on knowing in advance some information relating to anticipated load conditions (e.g., a desired power to be provided to a load). Based on “feeding-forward” known information about anticipated load conditions, power factor correction control loop response is significantly improved, particularly in situations in which the load power traverses a wide range in a short time period (e.g., load full off to load full on, or vice versa). As a result of improved control loop stability, smaller circuit components may be employed based on more predictable expectations for signal values, thereby reducing the cost and/or size of the implemented circuits. In one example, a processor controls both a feed-forward power factor correction apparatus and a feed-forward power driver for an LED-based light source to provide an efficient source of radiation using significantly streamlined circuits having fewer components and smaller space requirements.
