Discharge lamp unit with RF shield primary coil |
摘要 |
A discharge lamp unit has a housing provided with a lamp socket fitted thereon and accommodating a printed circuit board with a lamp lighting circuit and a high voltage generating transformer assembly mounted thereon. The transformer assembly consists of a primary coil being a plate conductor spirally wound around a coil case containing a secondary coil-wound bobbin with a core inserted in a hollow center thereof. The discharge lamp unit is formed as a single solid device by potting all of the components in the housing with insulating resin poured in a melted state and solidified therein. This unit is easy to mount with no need for laying a high-voltage between the circuitry and the lamp socket, and includes a very compact and light transformer having an increased conversion efficiency of the primary and secondary coils.
