Abstract:
1. An apparatus for curing an ultraviolet (UV)-curable coating material applied to a substrate surface, the apparatus comprising: a curing head comprising: a shroud defining an interior volume, the shroud forming an opening along one side, the opening positionable proximate the substrate surface; and a UV radiation source attached to the shroud, wherein the shroud is configured to direct UV energy from the UV radiation source through the opening of the shroud and towards a portion of the UV-curable coating material applied to a first area of the substrate surface that is aligned with the opening; and a supplemental light source attached to the curing head outside of the shroud, the supplemental light source configured to deliver light to a portion of the UV-curable coating material applied to a second area of the substrate surface that is located beyond the shroud and selected to reduce a curing potential of stray UV energy that escapes laterally beyond the shroud, wherein the supplemental light source comprises an incandescent light source, a halogen light source, a fluorescent light source, or an LED light source.
