<P>PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp lighting device, capable of reducing noise with a simple structure, while being small and inexpensive. <P>SOLUTION: The electrodeless discharge lamp lighting device comprises a first capacitance element 6 connected to terminal parts 3a, 3b, to which high frequency is applied in an LC resonance circuit 19. A second capacitance element 7 is inserted between a conductor 4 communicating to the terminal part 2a of an induction coil 2 and the terminal part 3a. A third capacitance element 8 is inserted between a second conductor 5 communicating to the terminal part 2b of the induction coil 2 and the terminal part 3b. The second and the third capacitance elements have approximately the same capacity. Insulation bodies 4a, 5a, around the first and the second conductors 4, 5 have approximately the same thickness. Retaining means for maintaining approximately a fixed distance between the first conductor 4 and the second conductor 5 is provided. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
