Abstract
The invention is a collapsible lampshade that helps conserve shipping and storage volume. Current invention consists of a rigid upper structures, a rigid lower structure, a flexible fabric joining the rigid upper structure and rigid lower structure, supported by several trapezoidal frames after the lampshade is assembled. Using trapezoidal frames to prop up the fabric, and hence completing the assembly process is easier and faster than other means of propping up and support the tension created by the fabric joining the rigid structures.
