摘要: An electronic lighting system and method described herein control energy provided to an device, such as one or more light-emitting diodes (LEDs) and/or compact fluorescent lamps (CFLs), of the system. A triac-based dimmer phase cuts a line voltage controller utilizes probing overcome idiosyncrasies allow probe sense voltage. To reduce consumption, rather than each cycle output dimmer, periodically intermittently probes dimmer.
