Air router for cooling light guide bundle

摘要

The present invention discloses an air duct for directing air onto an optical fiber bundle coupling. The air duct is used to siphon a portion of an air stream, which is used to cool an arc lamp, to the coupling end of the light guide bundle. After the air from the air duct cools the coupling of the light guide bundle, the air is routed back to provide additional cooling to the arc lamp.
