ELECTRODELESS PLASMA LAMP AND FILL

摘要

Electrodeless plasma lamp and fill is described. Power may be over coupled to the lamp during startup and a significant percentage of the power is reflected. In some examples, 40-80% of the power may be initially reflected and less than 100 watts of forward power may be provided to the lamp. A high pressure fill is used to increase resistance and coupling of power during startup. In one example, a fill of noble gas, Mercury and metal halide is used and the high pressure decreases the warm up time required to vaporize the Mercury and metal halide. In some embodiments, the pressure may be between 200 Torr to 3000 Torr. A combination of metal halides may be used to provide desired characteristics. For example, Aluminum Halide, Indium Halide and/or Thallium Halide may be combined with one or more metal halides having a metal from the Lanthanide series.
