中性色调起居室光照环境人因工学研究

Study on the Human Factors of Lighting in Neutral Color Living Room

对中国(以上海地区为主)起居室及其照明现状进行了深入调研,分析、总结了其基本功能布局与照明特点。基于调研结果,搭建了真实尺度的起居室模拟实验室。通过主观评价实验,从人因工学角度探讨了中国人对起居室光照环境中色温、光源及显色性的视觉偏好。总结了适合中国人的起居室照明设计策略,为半导体照明技术在起居室的应用提供研究基础和理论支持。通过研究,对主观评价实验的方法进行总结,为下一阶段实验提供理论及经验支持。结果显示:(1)色温与被试对空间的主观感受的相关性在数理统计上显著(P=0.001),并在一定范围内,在相同照度和光分布下,对比2700K,被试认为色温4000K的照明场景的主观亮度更高;(2)光源、显色性与被试对空间的主观感受的相关性在数理统计上不显著。

This research focuses on Chinese living rooms and their lighting environments .After a field survey the indoor functional layout and lighting status quo is summarized .A full scale living room is designed and built for subjective experiments , which is used to explore the Chinese people ＆#39;s preferences on color temperature , color rendering index and light sources .This study will also discuss the methodologies of subjective experiments and provides some theoretical and empirical support for the next stage of the experiment, to be reported later.The results of the first phase of the experiment show that： （1） the apparent brightness of 4000K lighting environment is higher than those of 2700K, （2） the effect of color temperature on people ＆#39;s subjective evaluation is significant , but the effect of light sources and CRI on people＆#39;s subjective evaluation is not significant .
