Electrodeless low pressure lamp with bi-static matching at 2.45 GHz

New RF-driven lamps allow an electrode-free burner configuration by melting down the electrode into the glass. The glass acts as a dielectric barrier coupling the RF power into the burner. This paper presents the development of a novel RF-driven lamp using bi-static matching including simulation and measurement results. Furthermore the influence of the glass thickness surrounding the electrode on the ignition and operation is compared. The optimal driving power of the different lamps is 400Watt / 56dBm.
