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. Based on various power driver configurations, lighting apparatus incorporating one or more power drivers for one or more LED-based loads may be implemented, and multiple such lighting apparatus may be coupled together to form a lighting network in which operating power is efficiently provided throughout the network.
