    Abstract: The invention relates to a method and apparatus for forming a coating over an inner wall of a tube. A method for forming a coating over an inner wall of a tube includes: winding a tube onto a mold to form the tube into a desired shape, when the mold is heated by a flame; and blowing a coating material with a first potential into the tube from at least one end of the tube, wherein the mold and the flame have a second potential and a third potential, respectively, which are different from the first potential, so that a coating is formed over the inner wall of the tube with the coating material by utilizing a potential difference between the first potential and the second and third potentials. The invention further provides a tube having at least one coating formed through such a method and a lamp including such a tube.
