Energy efficient multi-spectrum screen exposure system

摘要

A multi-spectrum screen exposure system for curing printing emulsions, including an enclosure with a platen that is transmissive to at least some ultraviolet wavelengths of light, a cover shiftable between an open orientation wherein the platen is accessible to an operator and a closed orientation wherein the platen is covered and inaccessible to the operator, a light emitting diode illumination (LED) light source assembly supported within the enclosure and oriented to direct illumination toward the platen, the light emitting diode illumination light source assembly emitting at least some light in the ultraviolet wavelengths, and a control unit operably coupled to the light emitting diode illumination light source assembly by which the light emitting diode illumination light source assembly can be operated in a controlled fashion.
