US Patent 10234116 Solar-powered lantern having collapsible shade structure

A portable and expandable solar-powered lantern that includes a light source, at least one solar panel in electrical communication with a battery to power the light source, and a self-erecting coil structure defining a frame covered by a compliant shade member. The frame includes an inner coil member coiled in a first direction relative to the longitudinal axis of the frame, and an outer coil member coiled in a second direction opposite to the first direction. The coil structure is moveable between a collapsed storage position and an expanded position, the compliant shade member limiting the length of the frame when the coil structure is in the expanded position.
