Abstract
PURPOSE:To suppress the increase of lamp current thus to prevent the increase of the ballast loss and to improve the total efficiency, by arranging the discharge shield across the filament coated with the electron emission subsistance to separate the discharge space at the end section of tube into two. CONSTITUTION:A counter U-shaped discharge shield 9 is provided across a filament 5 in the proximity of an electrode, where the base section of said shield 9 is fixed to a stem 4. Consequently the lamp current can be reduced without lowering the entire light flux emitted from the lamp, thereby a fluorescent lamp having high total efficiency can be obtained where the lamp current is reduced and the ballast loss is reduced without sacrifice of the advantage of high lamp efficiency of such fluorescent lamp as encapsulated with heavy rare gas such as krypton.
