ABSTRACT:
A discharge-lamp lighting device has a housing with a power supply socket formed therein and accommodating a printed circuit board with a coil case having a primary coil formed by plural parallel plate-conductors insert-molded around the body thereof and a discharge lamp socket integrally fitted thereon and including a secondary coil therein. A lamp lighting circuit is formed by mounting the coil case on the printed circuit board. The discharge lamp lighting device is formed as a single solid device by potting all the components in the housing with insulating resin poured in a melted state and solidified therein, thus eliminating the need of providing a high-voltage cable between the circuitry and the lamp socket.
