Multi-electrode array for a beam mode fluorescent lamp |
摘要 |
The lamp shown herein is a beam mode fluorescent lamp for general lighting applications. The lamp comprises a light transmitting envelope, having a phosphor coating on its inner surface, the envelope encloses a thermionic cathode having a number of segments for emitting electrons, a plurality of anodes for accelerating the electrons and forming a corresponding number of electron beams, and a fill material, such as mercury, which emits ultraviolet radiation upon excitation. The multi-electrode array configuration provides an extended region of electron beam excitation and thereby more visible light. A single power source and pair of connecting conductors perform both cathode heating current and electrode potential difference functions. In addition, this configuration provides for a greater and more complete discharge of the volume within the envelope than single electrode elements. The present invention permits a higher operating voltage, lower power density and a lower operating temperature for the lamp.
