Abstract
Systems are disclosed for providing ultraviolet (UV) energy to items on a processing surface. The system includes a lamp positioned over the processing surface to provide UV energy to the processing surface and a reflector cell positioned to cause UV energy emitted from the lamp in a direction away from the processing surface to be reflected toward the processing surface. The system includes the reflector cell having a reflector cap positioned above the lamp and a shroud extending downwardly from the reflector cap toward the conveyor wherein the shroud has a vertical dimension, a longitudinal dimension, and a horizontal dimension along the direction of the conveyor such that the horizontal dimension and the longitudinal dimension define a treatment area on the conveyor. The lamp is configured to deliver energy to the treatment area such that the delivered energy to the processing surface is substantially uniform over the treatment area.
