摘要： The invention relates to a retractable lighting fixture, comprising an elongated drum rotatable over a length axis; and a flexible multilayer lighting sheet movable between a retracted position and a protracted position, with the multilayer lighting sheet in the retracted position being at least partially retracted in one or more windings around the drum and with the multilayer lighting sheet in the protracted position being fully unwound from the drum; the multilayer lighting sheet being composed of at least one LED layer and at least one diffusing optical layer, the at least one LED layer having a first LED layer edge mounted at a first mounting position of the drum and the at least one diffusing optical layer having a first optical layer edge mounted at a second mounting position of the drum, the first mounting position being located at an arc length from the second mounting position.
