Abstract
A hanging decoration lamp with an active scenery disposed inside a transparent shell of a lamp constituting an illumination bulb has a plurality of glittering flakes and light grains made of foamed polystyrene. The transparent shell has a lid disposed at the top thereof and having a number of holes through which air can convect. The glittering flakes and light grains are made to move actively inside the shell as a result of air convection and the electrostatic force produced by the illumination bulb, making the scenery to appear vivid and active.
