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 housing; a flexible LED lighting sheet retractably retainable within said housing, said LED lighting sheet movable between a retracted position at least partially retracted within said lighting fixture housing and an extended position protracted from said lighting fixture housing more than said retracted position; said LED lighting sheet having a plurality of LEDs selectively electrically connected to a power supply; a plurality of electrical switches, each of said switches electrically interposed between at least one of said LEDs and said power supply; said switches actuable between at least a first state and a second state; wherein in said first state each of said switches enables electrical interconnectivity between said power supply and LEDs associated therewith; and wherein in said second state each of said switches prevents electrical interconnectivity between said power supply and LEDs associated therewith; and wherein each of said switches is in said first state when LEDs associated therewith are protracted from said lighting fixture housing; and wherein each of said switches is in said second state when LEDs associated therewith are retracted within said lighting fixture housing.
