ABSTRACT:
This invention relates to apparatus for cooling a mercury vapor lamp, or other longitudinally-extending body, by causing a flow of cooling air to pass along a conduit extending along the length of the lamp. The source of the coolant is a blower directing air along the interior of an open-sided housing extending in parallel with the direction of movement of the lamp. A scoop at one end of the conduit projects into the interior of the housing so as to direct the flow of cooling air passing along the housing into the interior of the conduit at all relative positions of the lamp and housing. In one preferred form of the invention the housing functions as one of the guide rails on which the lamp is mounted for reciprocal movement.
