Abstract: An improved lighting system (10) which in the preferred embodiment includes a cathode (12) having an external surface (34) being coated with a cathode outside film (40) for emitting electrons therefrom. A first anode (14) extends internal to the cathode (12) for heating the cathode (12) to thereby emit electrons from the external surface (34). A second anode (16) is positionally located external to the enclosed cathode (12) for accelerating the electrons emitted from the cathode external surface (34). A bulb member (18) encompasses the cathode (12), the first anode (14), and the second anode (16) in a hermetic type seal. The bulb member (18) has a predetermined gas composition contained therein with the gas composition atoms being ionized by the cathode emitted electrons. The gas composition ionized atoms radiate in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb member (18) is coated with a fluorescent material (20) for intercepting the ultraviolet energy responsive to the ionization of the gas composition atoms. The fluorescent material (20) radiates in the visible bandwidth of the electromagnetic spectrum to give a visible light output.

Abstract: In a preferred embodiment a lighting system contains a cathode 12 with an external surface 34 coated with an external cathode film 40 for the emission of electrons. A first anode 14 runs inside the cathode 12 to heat up the cathode in order to emit electrons from the external surface 34. A second anode 16 is arranged outside the cathode 12 to accelerate the electrons which are emitted from the external surface 34 of the cathode. A bulb body 18 surrounds the cathode 12, the first anode 14 and the second anode 16 in a hermetic seal. The bulb body contains a predetermined gas composition, the atoms of which are ionized by the electrons emitted by the cathode. The ionized atoms in the gas composition emit rays in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb body 18 is coated with a fluorescing material 20 to trap the ultraviolet energy originating from the ionization of the atoms in the gas composition. The fluorescing material 20 emits rays in the visible bandwidth in the electromagnetic spectrum and emits a visible light.

Abstract: According to the invention, a fluorescent tube is powered by a ballast system comprising a transformer connected to an AC power source via a rectifying diode. The primary winding of the transformer is connected in series with the power source and filament of the tube via a capacitor. The secondary winding of transformer is connected to in positive feed-back relation with the base (44) and emitter (42) of a transistor. The collector of the transistor is connected to the capacitor. The second capacitor is connected in series with the transformer secondary winding to apply a pulse voltage to the second filament of the tube.
