Abstract

A lamp assembly for use in the printing and coating industries has an elongate source of radiation and a reflector with an elongate reflective surface partly surrounding the source for reflecting radiation from the source down onto a substrate for curing a coating thereon. A shutter system is provided for shuttering the source to prevent radiation from reaching the substrate. The condition of the lamp assembly is monitored by shuttering the source and measuring the level of reflected radiation exiting through an aperture in the reflector.
