High frequency discharge energy supply means and high frequency electrodeless discharge lamp device |
摘要 |
Use of a side resonator group comprising a plurality of side resonators, each including both an electromagnetically inductive function section made of a substantially ringed conductive material and an electrically capacitive function section made of a gap, so arranged in a circle as to make said electrically capacitive function sections opposed to the center as high frequency energy supply means, enables a high frequency discharge to take place in a smaller space than that observed in use of a conventional cavity resonator. Besides, application of said high frequency energy supply means to a high frequency electrodeless lamp device enables high frequency energy to be effectively coupled even with a relatively small size of electrodeless discharge lamp. <IMAGE> |
