Abstract: A cathodoluminescent lamp includes an anode constituted by an electrically conducting coating on the interior surface of the bulb wall, a phosphor coating over the whole of the bulb wall interior, a dome-shaped grid located near the junction of the bulb with the envelope neck and supported on a hollow metal cylinder, and an electron emissive cathode mounted within the grid/cylinder assembly. The cathode may be effectively circular and located near the grid, or may be a linear filament located near the open end of the cylinder remote from the grid. In the latter case a metal disc, connected to the negative lead to the cathode, is located near the open end of the cylinder, to repel electrons emerging therefrom. The leads to the anode, cathode and grid lie within the neck and pinched foot tube closing the neck, and are connected to contacts carried by the lamp cap, the anode lead passing through the exhaust tube in the foot tube.

Abstract: A circuit and method for providing a DC control signal for setting the lighting level in an energy management control system, for maintaining the lighting level between preset minimum and maximum levels, and for providing either a gradual or a rapid transition between lighting levels, as desired. 
     An oscillator provides a square or rectangular waveform the amplitude or duty cycle of which is controllable during each of a series of control intervals, each interval including the same number of waveform cycles. During the first interval one waveform cycle (or more) is set at an amplitude or duty cycle corresponding to a desired lighting level, while the other waveform cycles of the first interval are set at an amplitude or duty cycle corresponding to the initial lighting level. During each succeeding control interval the number of waveform cycles corresponding to the desired level is increased by one or more, while the number of waveform cycles corresponding to the initial level is similarly decreased, until the last control interval contains only waveform cycles corresponding to the desired level; after which the circuit continuously generates a waveform having an amplitude or pulse width corresponding to the (new) desired level. 
     A rapid transition between the initial and desired levels can be provided by programmably reducing the number of control intervals to two, i.e. so that the first interval contains only waveform cycles corresponding to the initial lighting level and the second interval containing only waveform cycles corresponding to the desired lighting level. 
     The oscillator waveform, thus amplitude or pulse width modulated, is rectified and filtered to provide a DC control signal which gradually or rapidly varies from the initial level to the desired new level. The control circuit is configured so that resistance values therein can be set to maintain the waveform amplitude or duty cycle within a selected range in response to minimum and maximum level set command signals.
