GLOW DISCHARGE LAMP

摘要

The disclosure includes a glow-discharge lamp including: an elongate casing transparent to illuminating radiation and containing a plasma gas; a device for applying an electric field for maintaining a plasma in the so-called positive column region of the casing, the device including two electrodes forming an anode and a cathode located in the casing at each end thereof; and a radio-frequency or microwave cathode plasma source arranged in the casing in relation to the cathode-forming electrode, such as to generate a high-frequency discharge located on the surface of the electrode in order to generate the plasma. The disclosure also includes a lighting method of such a glow-discharge lamp.

主权项

1. A glow discharge lamp comprising:
an elongated envelope, transparent to lighting radiation and containing a plasma gas; a device for applying an electric field suitable for maintaining a plasma in the region of the envelope called a positive column, including two electrodes constituting an anode and a cathode situated in the envelope, at each end of the envelope; and a microwave or radio-frequency cathode plasma source positioned in the envelope relative to the electrode constituting the cathode so as to generate a localized high-frequency discharge on the surface of the electrode to generate the plasma.
