A lampshade is a covering for a light bulb that serves to protect it and to distribute the light in a certain direction. It usually consists of a frame, made from materials such as paper, plastic or fabric, which holds a translucent or opaque material intended to shield the light source from direct view while diffusing its illumination through the covering. Lampshades come in various shapes and sizes, designed for different types of lamps, including table lamps, floor lamps, desk lamps, and chandeliers. They can also be decorative or functional, serving as a design element to complement the room's décor while providing lighting.
