Retractable lighting fixture

摘要

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.

主权项

1. A retractable lighting fixture, comprising:
a lighting fixture housing; a flexible multilayer lighting sheet retractably retainable within said lighting fixture housing, said multilayer lighting sheet movable between a retracted position at least partially retracted within said lighting fixture housing and an extended position more protracted from said lighting fixture housing than said retracted position; said multilayer lighting sheet having a LED layer and an optical layer over said LED layer, said LED layer including a plurality of LEDs selectively generating a light output, said optical layer intersecting and transmitting at least some of said light output; wherein portions of said LED layer and said optical layer are in an expanded spaced relation to one another when in said extended position and in a compressed relation to one another when in said retracted position; and wherein the distance between said LED layer and said optical layer in said expanded spaced relation is at least two times the distance between said LED layer and said optical layer in said compressed relation.
