ABSTRACT:
A cathodolumineseent lighting system has a light emitting device having an envelope with a transparent face, a cathode for emitting electrons, an anode with a phosphor layer and a conductor layer. The phosphor layer emits light through the transparent face of the envelope. The system also has a power supply for providing at least five thousand volts of power to the light emitting device, and the electrons transiting from cathode to anode are essentially unfocused. Additional embodiments responsive to triac-type dimmers with intensity and color-changes in response to dimmer control. A power-factor-corrected embodiment is also disclosed.
