WAVE GUIDE SYSTEM FOR ELECTRODE-LESS LIGHTING DEVICE Russian patent published in 2007 - IPC H01J65/04 

FIELD: wave guide system for electrode-less lighting device.

SUBSTANCE: proposed is wave guide system for electrode-less lighting device, containing wave guide, directing microwave energy, originating from antenna of microwave generation means, which is stably inserted into internal surface of wave guide, and having a slit formed on internal surface of wave guide and connected to resonator, where envelope is positioned for feeding microwave energy into resonator, first rod, projecting from one internal surface of wave guide so that it is positioned close to slit, for synchronization of impedance with antenna and adjustment depending on output frequency of antenna; and second rod, projecting from internal surface of wave guide at certain distance relatively to first rod and extending pass band jointly with first rod, for adjustment depending on output frequency of antenna, changing in accordance to change of antenna impedance, while capability for injection of maximal microwave energy, emitted from antenna, to resonator, is provided, and stability of resonance is guaranteed.

EFFECT: possible control over pass band with small dimensions.
