Abstract:
A current regulator controls the electron emission from a cold cathode using closed-loop feedback from a current sensor in the cathode connection. The regulator circuit includes a cold cathode, a current-sensing element, a current-limiting element, and current-control element. Additionally, the closed-loop current regulator may comprise a reference element for generating the reference level, a circuit power supply and a cathode bias supply. The regulator and cathode may be assembled from separate components, or the entire circuit may be integrated onto a single substrate. In one embodiment, the current level is set by adjusting the reference element directly. In a second embodiment, the current level is set by adjusting the circuit power supply, so that the current level can be set remotely without the need to adjust the reference element directly. The second embodiment is preferably suited for the regulation of beam current in analytical instrumentation. In a third embodiment, the fixed reference element is replaced with a time-varying voltage signal. The current from the cathode then becomes a linear function of the time-varying reference signal. The third embodiment is preferably suited for application as an amplifying element or as the electron source in an emissive display.
Abstract:
A non-power generating current limiting device such as a field effect transistor is provided to output a regulated current in dependence upon a control voltage. An electron field emitter is connected to a drain or output of the non-power generating current limiting device to receive the regulated current. A tip of the electron field emitter emits electrons towards a collector anode. An extractor gate can be provided between the electron field emitter and the collector anode to control the rate of electron emission from the electron field emitter. Because the non-power generating current limiting device regulates the current to the electron field emitter, a maximum current output of the electron field emitter is limited to the regulated current from the voltage controlled current source. The electron field emitter is thus protected from destruction due to excess current. The non-power generating current limiting device can also be used to modulate electron emission from the field emitter.
Abstract:
A flashing and sound generating lamp that repeats on-off operation and generates a characteristic audible sound when an electric current is supplied to the lamp. The lamp comprises a thermally bendable member connected in series or in parallel with the lamp filament to effect on-off energization of the filament as a result of the bending of the member due to the presence and absence of radiant heat from the filament, and a concavity is prefabricated into the thermally bendable member to cause the member to bend with a snap action thereby to generate a characteristic sound each time the lamp is turned on and off.
