摘要
荧光玻璃凭借其出色的热稳定性、加工便利性及经济性,在现代大功率照明应用中占据了重要地位。传统的干法成型技术在制造复杂形状产品方面存在局限,促使科研工作者探索更多荧光玻璃成型工艺,如丝网印刷、旋转涂覆、凝胶注模和3D打印成型。这些湿法成型技术为荧光玻璃的制造提供了新途径。本文综述了荧光玻璃成型技术的研究进展,分析了干法成型的生产便捷性、丝网印刷的图案精确性、旋转涂覆的均匀性、凝胶注模的复杂形状制造能力以及3D打印成型的灵活性。这些技术在制备荧光玻璃的应用中优势明显,但也面临挑战。文章深入讨论了荧光玻璃湿法成型技术所面临的挑战,并对其未来发展的融合趋势进行了前瞻性展望,旨在为荧光玻璃材料的性能优化及应用拓展提供科学指导。
Phosphor-in-glass(PiG)occupies an important position in modern high-power lighting applications by virtue of its excellent thermal stability,processing convenience and economy.The limitations of traditional dry molding techniques in manufacturing complex shaped products have prompted researchers to explore more PiG molding processes,such as screen printing,rotary coating,gel injection molding,and 3D printing molding.These wet forming techniques provide a new way for the manufacture of PiG.In this paper,the research progress of PiG molding technology is reviewed,and the production convenience of dry molding,the pattern accuracy of screen printing,the uniformity of rotary coating,the complex shape manufacturing capability of gel injection mold and the flexibility of 3D printing molding are analyzed.The application of these technologies in the preparation of PiG has obvious advantages,but it also faces challenges.In this paper,the challenges faced by PiG wet forming technology are discussed in depth,and the fusion trend of its future development is prospected,in order to provide scientific guidance for the performance optimization and application expansion of PiG materials.
