Abstract
In accordance with certain embodiments, illumination systems include a flexible light sheet that may be wound within and unwound from, or folded within and unfolded from, a storage unit having a power source for powering light-emitting elements on the light sheet.
Claims28
An illumination device comprising:
- a flexible light sheet comprising (i) a flexible substrate, (ii) a plurality of light-emitting elements disposed over the substrate, and (iii) a plurality of conductive traces disposed on the substrate and electrically interconnecting the plurality of light-emitting elements;
- a storage unit configured to (i) accept and contain the light sheet in a rolled configuration therewithin, the light sheet being wound around an axis of the storage unit when contained therewithin, and (ii) dispense at least a portion of the light sheet therefrom via unwinding of the light sheet from the rolled configuration;
- a winding mechanism for at least one of winding or unwinding the light sheet around the axis of the storage unit;
- and
- disposed within or on the storage unit, a power source for supplying power at least to an unrolled portion of the light sheet and thereby illuminating the light-emitting elements of at least the unrolled portion.
