A Research Based On The Cirtopic Of Natural Lighting Of Office Space

This paper is the National Natural Science Foundation of China Youth FundProject "based on light biological effects of natural lighting and the visual effect ofoffice"(grant number:51108479) and Subtropical Building Science, State KeyLaboratory of "based on photobiomodulation of Subtropical Building Energy Research"(project number:2012KB19) for the study, focusing on the office space in the light ofbiological effects, and based on this the natural lighting office staff perception ofpsychological feelings, and physiological responses and natural light, for office space inthe light of biological effects of quantitative research provide a more scientific basis.There are third types of retinal photoreceptor cells--nerve cell (ipRGCs) studyfound, it passed on into the human visible light radiation generated in the biologicalresponse to control the human circadian rhythms, clock and pupil size, thus the body’sphysiology, mental health influence.Light on the human body for this non visualbiological reaction and effect is called Cirtopic (management optical non visual effect ofthe visual, or optical biological vision), referred to as "light biological effect".The office is in the people daily life work important venues, office space lightenvironment quality not only relates to people with eye health, but also to theirpsychological and physiological changes and biological reaction to the impact.Studieshave shown that, for the use of lighting performance in office building is veryimportant.But the existing lighting design standard for illumination, the illuminationuniformity of other visual effects for specification, lighting performance only on thebasis of the lighting coefficient, room depth and glare index assessment, withoutconsidering the photobiological effect; at the same time also lack of different regions oflight climate, seasons, lighting mouth toward the visual efficacy studies, thereforeunable to accurately reflect the office place actual lighting effects and worker’sphysiological and psychological feeling.Therefore, in the light of biological effectsunder the guidance of the theory, research is more suitable for office space lightingdesign ideas and measures, not only have office staff’s physical and mental health, butalso satisfy the building lighting energy saving significance, so as to realize greenlighting and health for lighting purposes.Perception of light is the main body of people, office space lighting developmentshould be more people-oriented, study of human visual perception psychology, physiological responses and visual effects such as optical biological effect, thus foroffice staff to provide a visual look easy, which is conducive to physical and mentalhealth, and improve the work efficiency of the office space lighting suggestion.Colourof light source and light biological effects are closely related, photobiological effect hasa specific spectrum, light, light intensity and pupillary characteristics.The light from thebiological effect sets out, comprehensive analysis of people’s subjective perception,physiological response, visual effects and different natural light color luminance,illuminance objective data change relations, embodies the combination of qualitativeand quantitative analysis for the study of strategy.Based on the real office room, byrecording under different weather conditions and natural color temperature of the lightsource of the visual task pupil size data and comparative analysis of natural lighting,office space in color and visual perception function relation, influence to workefficiency.Through visual perception psychology perception and physiologicalresponses of experimental analysis, research, further confirmed the colour of lightsource on human has obvious biological effects.In this paper, the natural lighting and office of photobiological effect combinationin Chongqing area, through the analysis of different light climate, seasons, lightingmouth towards, luminance levels in natural lighting conditions, pupil size, subjectivefeelings change rule, in the light of biological effect for, natural light (spectrum), lightintensity (brightness) and people’s visual psychological and physiological changes in therelationship between different color, finishing pupil change and the brightness level offunction type, with a view to put forward to meet the energy requirements for officeworkers and mental health, and improve the efficiency of office space light environmentplan, perfect office space daylighting health model, to further promote the green lightingand healthy lighting.
