The Primary Research On Quantification Of Chromatic Light Preference In Landscape Illumination

In the modern city, with the rapid development of social economy, the urbanconstruction is being completed day by day. The development of the urban landscapeillumination is paid extensive attention to by more and more people. The urbanlandscape illumination is developed and already been established as "the importantcomponent of urban environment and important infrastructure of city". But nowadayschromatic lights as the important expressive means in landscape lighting, have a lot ofproblems which are nonstandard in using and only rely on the experience whendesigning. So this article found out the scientific laws from these kinds of experiencethings, in order to instruct illumination design. It meant to carry on the basic researchon the psychogenic feeling tendencies which produces by chromatic lights simulatingin the laboratory, in order to finish the quantification of psychogenic feeling of colorlights. The research on quantification of chromatic light preference in landscapeillumination will have important meaning to realize city environment's highpsychological satisfaction and build suitable atmosphere.First, according to the deep research on some basic knowledge, such as the basiccharacter of color, the expression system of color, color temperature and the characterof showing color of lamp-house, the article confirmed the principle of the chromaticlights' choice in the research. And it completed the measurement and demarcation ofthe physical parameters which can exactly express these chromatic lights. And then,the article briefly analyzed the advantages and disadvantages of the subjectiveevaluation method. According to the fact of the research, it confirmed to simulate darkvision environment of landscape illumination in the lab by the way of the subjectiveevaluation investigation. I classified he confirmed homochromy chromatic lightsaccording their brightness, and used the computer projection system which had beenmeasured to project and reappearance, then carry on the subjective evaluationexperiment of chromatic light feeling preference faced to the people of big swatch. Onthe basic of various researches on the emotion effect of color itself made by formerpeople, I abstracted some refined index options which are used to express the mentalfeelings of seven chromatic lights and designed the subjective questionnaire.Through the statistical analyses on the experiment results of different people, Iconcluded and summed up the rule and degree of mentality cognizance and preferencewhen the testees feel the homochromy chromatic lights, and confirmed thequantification relationship truss of color lights "stimulation-response". It made thesubjective feelings transform into the quantified impersonal parameter. I made variouscontrast analyses among the several experiment results came from several differentexperiment people, and summed up some macroscopical and microcosmic regularconclusions. In the last chapter, I put forward the improvement ideas according to theresults of subjective evaluation experiment of homochromy color lights. In order tointegrate the fact of urban landscape illumination, I also simulated thethree-dimensional surface floodlight illumination of architecture. Then changed thehue and brightness degree of chromatic lights, used the computer projection systemwhich had been measured to project and reappearance, finally let testees evaluate andanalyzed the result simply.
