Probe stabilized arc discharge lamp

A probe stabilized arc discharge lamp comprising:

• 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 defining a gas in the chamber;
• a gas in the chamber;
• a first electrode disposed vertically in the chamber and extending outward through the base portion;
• a second electrode also disposed vertically in the chamber and spaced from and extending outward through the base portion, the second electrode spaced from the first electrode defining an arc gap between distal ends of the first and second electrodes;
• a trigger probe extending to or proximate to the arc gap for triggering an arc in the arc gap;
• and
• a reflector disposed about the arc gap for directing radiation generated by the arc out the window.

• a reflector disposed on the concave surface and about the arc gap for directing radiation generated by the arc out the window.

A cathode jig for a probe stabilized arc discharge lamp, the cathode jig comprising:

• a multiple piece body having a first section with an internal channel for receiving an anode therein and a second section with a concave cavity on the distal end thereof for receiving the distal end of a cathode;
• the first section having a circumference sized to coaxially align the cathode with the anode when the first section is disposed over the anode;
• and
• the second section having a length sized to correctly distance the distal end of the cathode from the distal end of the anode.

A probe stabilized arc discharge lamp comprising:

• a monolithic base portion and side wall portion defining a concave surface;
• a window spaced from the base portion and sealed with respect to the side wall portion defining a chamber;
• a gas in the chamber;
• a reflector disposed on or integral with the concave surface, the reflector having a focal point;
• an anode support extending through the base portion and an anode vertically supported by the anode support;
• a cathode support vertically extending up through the side wall portion, a cathode support arm extending horizontally inward from the cathode support, and a cathode extending vertically downward from the cathode support arm to a location spaced from the anode to define an arc gap at the focal point of the reflector;
• a trigger probe support extending vertically upward through the side wall portion and having a reduced circumference region proximate the side wall portion, and a trigger probe extending inwardly and downward from the reduced circumference region to or proximate to the arc gap for triggering an arc in the arc gap between the anode and the electrode;
• and
• a sparker assembly with a lead disposed in the chamber.
