Discharge lamp unit

摘要

A discharge lamp unit which 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 consisting 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 and which is formed as a single solid device by potting the inner 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 cable and includes a very compact and light transformer having an increased conversion efficiency of the primary and secondary coils. <IMAGE>
