摘要
传统印刷业中用于固化的光源多采用高压水银灯和金属卤素灯等,传统光源的紫外固化技术已经趋于成熟,不过由于光源本身和光学系统的局限,它们会聚出来的线形光线辐照度较低,且光场均匀度不够高,因此固化效率不够高。提出一种自由曲面透镜的设计方法,将发光二极管灯源和自由曲面透镜结合,可以有效实现光线聚焦的效果,提高光效和均匀性。使用三维机械设计软件SolidWorks设计透镜的初始结构,将透镜模型导入光学优化软件LightTools中对透镜进行光线追迹模拟。通过建立目标函数,执行优化方案,对出射光的均匀度、辐照度不断进行优化,实现出射光为高亮度、高均匀度的线形光。
Abstract
In the traditional printing, curing light source always uses high pressure mercury lamp, metal halide lamp and so on. The traditional light source of ultraviolet curing technology has been matured. But because of the light source itself and the limitations of the optical system, the linear light radiation intensity of illumination is low. And the uniformity of the light field is not high enough. This paper provides a design of freeform surface which makes the emergent light of ultraviolet-LED becoming a linear light source effectively. The SolidWorks software is used to design initial structure of the lens. And then the structure is imported into LightTools software to simulate the light. The light is optimized by establishing the objective function and changing the parameters, so that the emergent light can present high brightness and high linear light evenness.
