Investigation Research on Lighting Environment Improvement of Outdoor Rescue Work at Night

本研究的目的是了解救援和医疗工作者在夜间户外工作时的障碍，如照明条件差和视觉物体因素，提取在夜间医疗工作救援活动的现状下，有关能见度和颜色条件的问题，并提出改善照明环境的建议，以确保更好的救援和医疗活动在未来。首先，我们对救援人员进行调查，提取出在灾难情况下的视觉环境的需求和问题。应该注意的是，在光通量、照射面积和显色性方面存在差异。关于设备规格的信息输入也应标准化。此外，我们报告收集光谱反射率数据，并建立彩色图表数据库的准皮肤在休克和充血状态下的健康青年/老年人的主题，以确定视觉条件下的灾难受害者的皮肤埋在瓦砾。在此过程中，我们研究了性别和年龄的影响。此外，我们开发的方法，高速连续测量的亮度分布在视野中使用运动图像，以评估在夜间救援情况下的适应亮度。

The purposes of this study are, to understand obstacles for rescue and medical workers such as poor lighting conditions and visual object factors at night time outdoor works, to extract problems regarding visibility and color conditions under current situations of medical work relief activities at night time, and to make proposals for the improvement of the lighting environment in order to secure better rescue and medical activities in the future. First, we conduct survey to rescue workers to extract needs and problems of visual environment in disaster situation. One should take note that there are differences with regard to luminous flux, irradiation area and color rendering. There also should be standardized input of information on specifications of equipment. Moreover wereports collecting the spectral reflectance data and creating the color chart database of quasi-skins in shock and congested state by healthy young/ elderly subjects, in order to determine the visual conditions of disaster victim’s skin under a situation like buried in rubble. In so doing we examine the influence of gender and age. Also, we develop the methods of high speed continuous measurement of luminance distribution in the visual field using moving images in order to assess the adaptation luminance in the nighttime rescue situation.
