    Abstract: One example solid state lighting type lamp for a three-way luminaire includes a power source, a controller, an output stage, switching logic circuitry and multiple sets of light emitters. The logic circuitry receives input signals from tip and ring power contacts on a lamp base. The controller provides power from the power source to the output stage which is controlled by the switch logic circuitry to selectively apply power to different ones of the sets of light emitters responsive to the input signals. Each set of light emitters emit light having different color temperatures. In another three-way luminaire example, the control circuitry is configured to control drive current in a sequence to toggle the lamp consecutively between an OFF state and ON state in response to inputs from a three-way socket. Another type of lamp includes circuitry to permanently disable the lamp on detection of an end-of-life condition.

    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.
