摘　　要：印制电路板生产设备紫外线曝光机的光源系统,其能耗大、使用维护成本高、含汞等缺陷,在倡导节能环保的当今,业界一直致力于改进。UV-LED面光源作为新一代绿色环保紫外线光源,为印制电路板曝光领域带来革命性的变化。文章通过分析传统平行光紫外曝光机光学系统特点,设计了一种平行光紫外线曝光机适用的UV-LED面光源系统,UV-LED灯珠光功率利用率大幅提高,光照均匀性优良,并且不改变曝光机结构的情况下,可直接安装使用。实验表明,采用了复眼式阵列光学透镜结构设计的UV-LED面光源系统,完全可替代传统平行光紫外曝光机光源。The light source system of ultraviolet exposure machine which is the PCB production equipment, has high energy consumption, high using and maintenance costs, mercury and other defects. To promote energy-saving environmental protection industry today, the industry has been working to improve. UV-LED surface light source as a new generation of green ultraviolet light source, brings the revolutionary change for the PCB exposure ifeld. In this paper, through the analysis of features of the traditional collimated light ultraviolet exposure machine, it designed a kind of UV-LED surface light source system for the collimated light ultraviolet exposure machine, a substantial increase in UV-LED light pearl power efifciency, illumination uniformity is good, and does not change the exposure machine structure, can be directly installed. Experiments show that, the UV-LED surface light source system using the optical lens structure of lfy＆#39;s eye array can completely replace the traditional collimated l light ultraviolet exposure machine light source.
