<p>A method of completely eliminating electrophoresis effect in a DC fluorescent lamp tube is discovered, which belongs to the electric lamp technology field, and is used for a DC fluorescent lamp. It is characterized in that the method comprises individually and/or simultaneously changing relative position of the cathode and the anode in two ends of the tube and structure of the same, coating a infrared thin film which is transmitting light at either inside or outer wall in the cathode end, disposing a mercury-absorbing metarial in a exhaustung tube in the anode end, mounting a thermal insulation sealing cover having high transmissivity below a lamp shade, and adding Kr and Xe gas at 20-60 % by volume in total inert gas. It has advantages that can completely eliminate 'electrophoresis effect' in a DC fluorescent lamp tube, solve a worldwide difficulty, lengthen life of the lamp tube, simplify the structure and reduce the cost, and so on.</p> |
