Abstract (en)
The lamp shown herein is a beam mode fluorescent lamp for general lighting applications. The lamp comprises a light transmitting envelope (31), having a phosphor coating (37) on its inner surface, enclosing a single electrode (29) including a thermionic cathode (34) for emitting electrons and an integral anode (35) for accelerating the electrons and forming an electron beam, and a fill material, such as mercury, which emits ultraviolet radiation upon excitation. The electrode configuration provides for use of a single power source and minimal number of power leads. In addition, a separate cathode heater filament is not required.
