1. An illumination apparatus comprising:
- a plurality of LEDs;
a control system connected to receive dimmer-modulated AC line voltage and control the plurality of LEDs, the control system configured to;
operate in a default mode wherein changes in dimmer-modulated AC line voltage adjust a first characteristic of the plurality of LEDs until the dimmer-modulated AC line voltage manifests a first mode change condition;
enter a scanning mode upon determining that the dimmer-modulated AC line voltage manifests the first mode change condition wherein the control system automatically adjusts a second characteristic of the plurality of LEDs to scan through a range of adjustment settings; and
,set the second characteristic of the plurality of LEDs based on a current setting in the range of adjustment settings and enter a different mode upon determining that the dimmer-modulated AC line voltage manifests a second mode change condition.

23. A method for controlling an LED-based illumination apparatus comprising a plurality of LEDs, the method comprising:
-
receiving dimmer-modulated AC line voltage; controlling the LEDs in a default mode whereby changes in the dimmer-modulated AC line voltage are transformed into changes in a first characteristic of the plurality of LEDs until the dimmer-modulated AC line voltage manifests a first mode change condition; controlling the LEDs in a scanning mode upon determining that the dimmer-modulated AC line voltage manifests the first mode change condition wherein in the scanning mode a second characteristic of the plurality of LEDs is automatically adjusted to scan through an available range of adjustment settings; and
,setting the second characteristic based on a current setting in the range of adjustment setting and controlling the LEDs in a different mode when the dimmer-modulated AC line voltage manifests a second mode change condition. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
