A lamp 2 for curing inks comprises elongate radiation source 18, an elongate reflector partly surrounding source which comprises three spaced elements 4, 6, one above source 18 and one either side. According to a further invention a lamp 2 comprises a hole 16 in elongate reflector 4 above elongate source 18, shutters 6 either side of source 18 and an extractor which draws air over source 18 and through hole 16, so that when shutters 6 are closed air is drawn into lamp 2 over the top of shutters (fig. 1B). In a third invention a lamp 2 comprises an aperture in elongate reflector 4 through which radiation from elongate source 18 can be measured by monitor (26, fig. 4) when shutters 6 are closed. Shutters 6 may be the side reflectors 6 and comprise a body 8 with passages 10 for cooling fluids and a reflective sheet 12 coated with a dichroic coating and attached by releasable clips 14. Reflectors 6 may have a straight or only slightly curved reflective surface. |
