Abstract
A probe stabilized arc discharge lamp including a base portion, a window spaced from the base portion, a side wall interconnecting the base portion with the window. The side wall, the base portion, and the window define a chamber. A first electrode is disposed vertically in the chamber and extends outwardly through the base portion. A second electrode is also disposed vertically in the chamber and is spaced from the first electrode. The second electrode extends outwardly through the base portion. The first and second electrodes define an arc gap. There is also at least one trigger probe extending to or proximate to the arc gap for triggering an arc in the arc gap. Also, a reflector is disposed about the arc gap for directing radiation generated by the arc out the window. A sparker may also be provided.
