Comprehensive evaluation of the visual impression of artificial lighting luminous environment for the residential living room

Based on the field survey and the analysis of typical civil residences, a experimental model of artificial lighting luminous environment for residential living rooms was established, and psychological evaluation indexes including spaciousness, pleasantness, privacy, clarity, order, relaxation, subjective impression of colour temperature and glare were made. Furthermore, the property matrix was set up after sampling survey and evaluation of lighting experts. With the method of mean square deviation, a comprehensive evaluation function was proposed for living room with verification by experts grading. It is found that the comprehensive evaluation function matches experts grading very well. For the average illumination of about 150lx at the horizontal plane of 0.75m, people would get the higher psychological satisfaction when the uniformity of illumination is 0.4 to 0.5 in artificial lighting luminous environment, while the lower psychological satisfaction would get when the uniformity of illumination is greater than 0. 6.
