Abstract
PURPOSE:To facilitate the start of discharge without requiring the thermal decomposition in vacuum and to prevent the blackening due to the impurity gas, by applying the electron emission substance such as titanic acid barium on the electrode of a tungsten coil filament having specific cold resistance. CONSTITUTION:A phosphor film 3 is stretched over the inner face of a tube type light permeable air-tight container 2 of a fluorescent lamp 1, while the electrodes 4 are encapsulated at both end sections of the container 2. An electron emission subsistance 5 produced by burning the powder of titanic acid barium or titanic acid barium.calcium is spread over the tungsten filament of the electrode 4. The tungsten filament of the electrode coated with the electron emission subsistance 5 has the cold resistance or the electric resistance at 30 deg.C of 0.8-1.8OMEGA. Consequently sufficient electron can be emitted from the electron emission subsistance resulting in the facilitation of the start of discharge of the fluorescent lamp and the prevention of the blackening phenomena.
