A shutter apparatus for a curing lamp housing is provided. The shutter apparatus
may be pulled out of the housing along ribs. The ribs slide with respect to recesses
formed in rails of the shutter apparatus. When the shutter apparatus is pulled
out of the housing, easy access to fasteners holding the shutters onto drive and
pivot shafts enables the shutters to be readily replaced. A method detailing such
replacement is also provided. A drive mechanism enables the shutters to be opened
and closed in unison.
