Abstract
Methods and systems are provided that control devices using signals transmitted over power lines in many different applications and configurations. They provide a lower cost approach for controlling devices via signals transmitted over power lines. The methods and systems may control intensity, spectral, and other characteristics of lighting devices, such as light-emitting diodes (LEDs) or assemblies thereof, via power lines. They may also control other types of loads, such as motors, relays, valves or the like. Additionally, techniques for independently controlling intensity and spectral content of selected high efficiency lighting devices are also described. For example, the brightness and color of an LED may be controlled via the power lines that supply power to the LED.
