不同光源对室内光感觉评价的影响与应用

本文主要通过不同光源在普通办公作业下,对室内光环境舒适性的实验研究,以确定适宜的光源选择策略。本次研究主要针对节能灯和白炽灯,采用现场测试+问卷调研的方法,开展两种光源作用下的室内光环境照度的变化情况测试,同时进行室内人员感观问卷调研。文中首先对不同光源的感观评价进行了分析,得到了两种光源的室内照度舒适区间;其次,讨论了光源颜色对室内照度的光感觉评价的影响;最后针对不同光源类型简要地进行了节能性分析。结果表明:不同光源作用下,人员对室内光感觉较舒适区间存在一定差异性,节能灯下人员光感觉较舒适的区间为310～600lux,白炽灯下为400～500lux,而光源颜色是造成室内光感觉舒适性区间差异的影响因素之一;节能灯相比白炽灯节能效果显著,平均每日节省电量5.5度。在普通办公建筑中,人们在使用照明时,应根据光源类型,进行合理的照度值选择,实现绿色照明。

Influence and Application of Different Light Source on Indoor Light Perception Evaluation

This paper presents an experimental study about the influence of different light sources on indoor lighting environment comfort during the general office work.This study mainly aimed at energy-saving lamps and incandescent lamp,adopting the method of questionnaire and measurement to determine suitable source selection strategy.Indoor illuminance was measured in physical means while conducting questionnaire surveys for the two light sources.Firstly,The indoor illumination comfortable interval was gained based on subjective scales used for the study on the sensory evaluation of the two light sources;Secondly,the influence of light color on indoor lighting feeling was discussed;Finally,the energy conservation of the two lamps was also analyzed.The results indicated that the illuminance comfortable interval for the self ballasted fluorescent lamp was 310～600lux,and for the incandescent lamp was that of 400～500lux.The light color was an important factor causing the difference of two lamps＇ comfortable interval.The energy conservation of two lamps was also analyzed,the result indicated that energy conservation of self ballasted fluorescent is significant with average 5.5 kwh electricity saving daily compared with incandescent lamp.People should selet illumination value reasonably based on the kind of light source to realize green lighting in the ordinary office building.
