Abstract
Disclosed is a retractable lighting fixture having a retractable LED lighting layer. One or more optical layers (40, 240A/B, 340A/B, 440) may optionally be provided over the LED lighting layer (30, 230, 330, 430). The optical layer(s) and the LED lighting layer may optionally be movable relative to one another between at least being in an expanded spaced relation to one another and a compressed relation to one another. One or more LEDs (34, 134, 234A/B, 334A/B, 434) on the LED lighting layer may be individually controllable and such LEDs (34, 134, 234A/B, 334A/B, 434) may be selectively extinguished when they are in a retracted position.
