Ultraviolet illumination system for use in printing industry has strip light in focus of two-dimensional parabolic fixed reflector and has movable flat mirror to deflect light away from absorber

摘要

The ultraviolet illumination system (30) has a strip light (31). This is placed in the focus of a two-dimensional parabolic fixed reflector (32). An approximately parallel beam of light leaves the lamp and reflector assembly. A flat pivoting mirror (35) is mounted in front of the lamp and the parabolic mirror to deflect ultraviolet light away from an absorber. The flat mirror may be placed parallel to the light beam to let most of the light through, or may be turned through 45 degrees to reflect the beam through 90 degrees. The flat mirror may be made in several sections (35.1-35.3).
