Abstract
A system and method for dimming an LED lighting installation using an AC power source are disclosed. The disclosed LED lighting system includes an LED light having one or more LEDs, a dimming control module for controlling and adjusting brightness level of the LED light toward a desired target brightness, and a user-operated lighting control device including a power on/off switch and a dimmer. The power on/off switch passes or interrupts the AC power fed into the dimming control module. A series of turned-off operations of the power on/off switch of transitory duration causes LED light target brightness levels to be progressively increasing or decreasing leading to a desired target brightness. Operations of the dimmer result in a target brightness setting signal being generated for the dimming control module, representative of a desired target brightness as well.
