BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention.
FIG. 1 is a schematic view of a conventional cold mirror UV curing lamp housing;
FIG. 2 is a schematic view of the conventional cold mirror UV curing lamp housing of FIG. 1 illustrating how some of the light generated by a light source is reflected by a band-pass filter so as to leave the housing via a window, whereas other light generated by the light source passes through the band pass filter and into a heat sink;
FIG. 3 is a schematic view of a conventional hot mirror UV curing lamp housing in which some of the light generated by a light source is transmitted through a band-pass filter so as to leave the housing via a window, whereas other light generated by the light source is reflected by the band pass filter;
FIG. 4 is a schematic view of a cold mirror UV curing lamp housing of the type shown in FIGS. 1 and 2 but additionally including a second heat sink behind the web;
FIG. 5 is a schematic view of a hot mirror UV curing lamp housing of the type shown in FIG. 3 but additionally including a heat sink behind the web;
FIG. 6 is a schematic view of an electron beam curing housing;
FIG. 7 is a break-away, perspective view of the window outlet of a UV curing lamp housing such as one of the types shown in FIGS. 1, 2, and 4 and a web passing thereby, the view showing that the length of the light source is greater than the width of the web;
FIG. 8 is a schematic view of a curing device that includes a curing housing such as one of the types shown in FIGS. 1-6 and a control system; and
FIG. 9 is a block diagram that depicts an embodiment of a control method according to the present invention.
