The lampshade of the present disclosure may thus allow for the convenient and quick interchanging of different covers with each other on the upper rigid frame and with the lower rigid frame as desired.
Such a lampshade may provide much greater benefits than a conventional lampshade which securely fastens or sews the cover around the frame of the lampshade. To replace the cover of a conventional light shade, the entire light shade must be replaced, which means that the mechanical fasteners connecting the frame of the light shade to the lighting assembly must be removed to remove the light shade from the lighting assembly. Then, mechanical fasteners must be used to mount the new lamp cover to the lighting assembly.
