Abstract

A plasma light bulb, comprising a hollow sphere (1) of a translucent material, a substance (3) within the hollow sphere, wherein the substance can be excited electromagnetically so as to form a plasma, which radiates visible light, and a stem (5) protruding from the hollow sphere, wherein the hollow sphere is tip- or tail-less, and the stem is bonded to the hollow sphere.
