<P>PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp lighting device capable of making low in height and easy in manufacture. <P>SOLUTION: The lighting device is provided with a filling frame 4 which surrounds a conductive pattern provided on a printed surface of a printed-circuit board 1 in a face extending along the printed surface, and a sealing resin 3 which is filled in the filling frame 4 and covers the conductive pattern. The printed-circuit board 1 is supported with a gap between the inner face of a housing 2 opposed to the printed surface of the printed-circuit board 1 and the sealing resin 3. At the sealing, since leakage of the sealing resin 3 is prevented by the filling frame 4, a sealing resin 3 of low viscosity can be used, thereby, manufacturing becomes easier compared with the case in which conductive pattern is sealed by coating of the sealing resin 3. Furthermore, compared with the case in which the printed-circuit board 1 is sealed by filling the sealing resin 3 in the housing 2, the height of the lighting device can be reduced and the distance between the printed-circuit board 1 and the housing 2 can be made small, while restraining the stray capacity between the conductive pattern of the printed-circuit board 1 and the housing 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
