  • System and method for selectively dimming an LED
    Patent number: 8729810
    Abstract: Embodiments of the present disclosure include an LED ballast circuit for dimming one or more LEDs using a phase controlled dimmer switch. The LED ballast circuit has a power conditioning unit which includes a substantially fixed duty cycle clock for outputting a clock cycle and a transformer configured to store energy and discharge a substantial portion of the stored energy once per clock cycle in order to power one or more LEDs.
    Type: Grant
    Filed: March 23, 2012
    Date of Patent: May 20, 2014
    Assignee: Permlight Products, Inc.
