Abstract

PURPOSE:To prevent the condensation of discharge gases in each luminous chamber of a lamp selectively made luminescent via luminous chambers separated from but adjacent to one another as a common electrode by providing a divisional plate in each luminous chamber and bending a discharge route. CONSTITUTION:A plurality or, for example, four square luminous chambers 2R, 2G1, 2B and 2G2 are adjacent to one another. Each luminous chamber is respectively provided with main electrodes 5R, 5G1, 5B and 5G2 and one of the electrodes is selected, thereby causing discharge lighting with a common electrode 6. Discharge gases are common via communication holes 3R, 3G1, 3B and 3G2 formed on each luminous chamber. By providing a divisional plate 19 between the communication hole and the main electrode in each luminous chamber, a discharge route is bent in an approximate U-shape along the divisional plate 19 and passes uniformly through all luminous chambers without any deflection and the discharge gases become uniform in thermal distribution, thereby preventing the condensation thereof.
