| Title: |
Method for Cooling an Arc Lamp |
| Abstract: |
A xenon arc lamp for a motion picture projector is cooled by providing the
anode end of the lamp with a shroud that forms part of a support for that
end of the lamp. Cooling air flows into the shroud along the support arm
and enters the shroud through a slot in its side wall. The shroud provides
an annular air space around the anode end of the lamp and has an annular
air outlet through which the cooling air leaves as a "sheet" of laminar
air flow which tends to adhere to the surface of the bulb, thereby
providing precise cooling. In this way, arc instability is avoided or
minimized, while lamp life is extended.
