为了简化手术灯照明系统的光学结构, 设计了一种新型宽入射角调色温冷反射镜。分析了医学手术灯的光谱技术要求, 分别使用三角垂直插值法计算光源系统的相关色温和标准三刺激值计算法计算显色指数编制程序计算。对比一种普通色温调整膜系的计算结果, 通过膜系和反光镜面型的优化设计, 得到了一种新型宽角度调整色温薄膜。实现了光线入射角度较大的范围内变化时, 出射光的色温变化小的要求, 显色性良好。这种薄膜减了小了手术灯整体结构的复杂程度, 提高了光能利用效率, 可以替代传统的手术灯光学结构。

The paper mainly discusses the design of a simplified operating lamp structure——an increase color temperature reflector with wide incident angle. We analyze the spectrum requirement on surgery light by using vertical triangular interpolation calculate color temperature and Tristimulus calculate color-rendering Index. And by comparing one result of an ordinary thin film, we optimized the design of on the film and shape of the reflector and designed a new color temperature reflector with wide incident angle. And the color rendition of the new design is even better when the incident angle changes in a wide range.As a result, the design of thin film decreases the complexity of the surgery light structure and enhanced the applying efficiency for the light which can be used as a replacement of traditional operating lamp structure.
