Lamp Assembly

摘要

A lamp assembly for curing of inks or the like has an elongate UV radiation source 26 partly surrounded by an elongate reflective surface. Air is supplied from above the source and an air vortex is generated such that the cooling air flows around the source 26. The vortex may be generated by supplying the air tangentially and to one side of a elongate UV radiation source 26 and/or by providing the reflective surface with an appropriate profile and/or by use of at least one filter 40.
