Discharge lamp lighting device

摘要

A discharge-lamp lighting device has a housing (7) with a power supply socket (8) formed therein and accommodating a printed circuit board (5) with a coil case (2) having a primary coil formed by plural parallel plate-conductors insert-molded around the body thereof and a discharge lamp socket (1) integrally fitted thereon and including a secondary coil (4) therein. A lamp lighting circuit is formed by mounting the coil case (2) on the printed circuit board (5). The discharge lamp lighting device is formed as a single solid device by potting all the components in the housing (7) with insulating resin poured in a melted state and solidified therein, thus eliminating the need of laying a high-voltage cable between the circuitry and the lamp socket. <IMAGE>
