ABSTRACT:
A xenon short-arc lamp system includes a choice of two anode heatsinks with different mechanisms for thermally interfacing to, and supporting, e.g., a 300W-400W xenon short-arc lamp. One heatsink, allows a conventional mounting in which a split ring and clamp combination accommodate and clamp to a screw-on base adapter fitted to the 300W-400W xenon short-arc lamp. The lamp can then be operated at 300W. The second heatsink accommodates the 300W-400W xenon short-arc lamp directly without the adapter. A large threaded stud on the lamp is screwed directly into the heatsink and is seated such that a large orthogonal flat planar annular ring area also makes a tight thermal connection. The lamp can then be operated at its higher limit because of the much improved thermal resistance.
