摘要
本文分析了手术灯隔热、色温调整及高显色性的光学技术要求,采用在隔热玻璃基片上镀制多层干涉薄膜,设计了具有升色温、高显色性与隔热性能的手术灯用滤光片,再利用色温与显色指数模拟计算软件,对滤光片膜系及光谱进行了优化设计。采用该滤光片设计的手术灯色温达(4200±150)K,显色指数>92,隔热性>99%,达到了设计要求。
This paper introduces optical technology requirements for heat insulation, color temperature adjusting and high color rendering of surgical lights.Adopting the structure of multilayer interference films deposited on the heat-protecting glass substrate, the filter with functions of rising color temperature, high color rendering and heat insulation for surgical lights is designed. Simulation software using color temperature and color rendering index is developed, and the filter film series and spectral are optimally designed. Color temperature is （4200±150） K, color rendering index is greater than 92 and the insulation resistance is greater than 99% for the surgical lights which meet design requirements.
