    • A light source for a photo-reactive curing apparatus is provided, which includes a plurality of light source elements or modules, such as, UV or visible LEDs or LED arrays, arranged to provide a beam profile comprising irradiation zones separated by a dark zone. Photo-polymerization occurs during periods of irradiation and dark polymerization occurs during dark intervals between irradiation. The relative positioning or spacing of light source elements or modules is set to provide an exposure profile with a dark interval which matches the required dark reaction interval for optimal curing efficiency. In modular or adjustable light sources, the spacing is adjustable dependent on process parameters. For processes such as inkjet printing, the beam profile may be better matched to the ink chemistry, so as to control the polymerization reaction to meet a required process speed for single pass or multiple pass applications.
    • 提供了一种用于光反应固化设备的光源,其包括多个光源元件或诸如UV或可见LED或LED阵列的模块,其布置成提供包括由暗区隔开的照射区域的光束轮廓。 在照射期间发生光聚合,并且在照射之间的暗间隔期间发生暗聚合。 光源元件或模块的相对定位或间隔被设置为提供具有与所需的暗反应间隔匹配的暗区间的曝光分布,以获得最佳的固化效率。 在模块化或可调光源中,间距可根据工艺参数进行调整。 对于诸如喷墨印刷的工艺,光束轮廓可以更好地与油墨化学性质匹配,以便控制聚合反应以满足单程或多次应用所需的加工速度。
