Abstract

A furlable lamp includes a translucent flexible sheet having left and right halves, a bent spine connecting the left and right halves, an opening and a space located between the left and right halves, a supporting structure including a plurality of hollow frame pairs and a light base pair, and a light source disposed on the light base pair. The opening is gradually narrowed from a first end to a second end of the translucent flexible sheet. Each of the hollow frame pairs and light base pair, which are arranged one by one from the first end to the second end of the translucent flexible sheet, includes left and right units symmetrically fixed on the left and right halves of the sheet respectively. The furlable lamp is capable of furling and unfurling to change the shape and light-emitting effect thereof.

Dependent claims

A furlable lamp comprising:

a translucent flexible sheet comprising a left half and a right half hingedly connected with the left half such that the left half and the right half are foldable relative to each other, the translucent flexible sheet being configured in a curved manner with a space within the left half and the right half and an opening gradually narrowed from a first end of the translucent flexible sheet to a second end of the translucent flexible sheet;
a supporting structure connected with the translucent flexible sheet and configured to constrain the translucent flexible sheet to furl in a way that the second end of the translucent flexible sheet moves toward the first end of the translucent flexible sheet when the opening is widened, and constrain the translucent flexible sheet to unfurl in a way that the second end of the translucent flexible sheet moves away from the first end of the translucent flexible sheet when the opening is narrowed;
and
a light source disposed to the second end of the translucent flexible sheet in the space for emitting light in the space and out of the opening.
