I am trying to power a deuterium lamp. I have a power supply for the tungsten filament and another for running the arc from the filament to the anode.

What I need is an igniter circuit. I have considered using a piezo igniter but I am worried about the power supply components. I've been looking at a ballast that had an input side transformer burn out, my first pass at a diagram is posted.

The pins are to a L6561 power factor correction IC, there are some oddities EG pin 5 only goes to ground... however my REAL quandry is how the bulb side works.

If it's not obvious, L5-L10 are one side of a transformer and L11 is the other side. I have found almost no information on transformers, flyback or otherwise, with 7+2 pins. I think this is an oscillator circuit?

The other issue is on the power side, the initial transformer seems like it's purely for isolation (AKA 1:1) so since that's what burned out I'm tempted to hook 110 up to the diode bridge.

Can anyone help me out with this?

 

For ignition may be used a) high voltage sparklet galvanically isolatod fro grid (batteries driven) b) another ICP or CCP lamp just near it to the output window c) any other hard UV source d) even moderate beta emitter from weak radioactive element like thoriated welding (TIG) rods. The simplest way how to build the (a) is battery, resistor to lade up 1 uF capacitor, and dinistor to the vehicle spark coil or TV kinescope coil to consume this charge.
