摘　　要：光环境作为菜市场物理环境的重要部分,对农产品的颜色呈现具有较大影响,决定了购买者对农产品的品质评价。当前,针对LED光源相关色温对农产品颜色感知的影响研究较少,存在着不同类型农产品外观展示的适用光源无法明确的问题。为了探究中国人对菜市场展示光源的视觉偏好,改善菜市场照明环境质量,提高购买者的体验感和满意度,本研究基于菜市场光环境现状调研结果,以蔬菜、水果和鲜肉三类典型农产品为观察样本,选择不同相关色温的LED(2500 K、3000 K、4000 K、5000 K、6500 K)作为测试光源,通过心理物理实验,从人因工学角度探讨LED光源相关色温对农产品颜色感知的影响。研究表明:当测试光源相关色温增加,农产品更加接近标准光源下的颜色,显色指数不能很好地反映光源的颜色还原性;不同类型的农产品在色彩偏好度上具有差异,水果的偏好度在相关色温4000~5000 K时最高,蔬菜类的偏好度在相关色温5000~6500 K时最高;测试光源下,人们对鲜肉的色彩偏好度总体低于水果和蔬菜。本研究探讨了菜市场光源相关色温对农产品颜色感知的影响,为中国人色彩感知研究和LED光源在菜市场中科学合理的应用提供参考与依据。The light environment is an important part of the indoor physical environment of wet markets,especially the display light source have a large impact on the color rendering of agricultural products,it determines the quality judgment of the purchasers.Therefore,quantitative evaluation of color rendering of light source is an important aspect to study light environment of wet markets.In recent years,relevant scholars have discussed the color rendering of LED light sources and the evaluation of LED lighting for Chinese human eye vision,and have made efforts to improve the color rendering of LED light sources.However,there are few studies on the influence of LED light source correlated color temperature(CCT)on color perception of agricultural products,and there is the problem that the characteristics of light sources suitable for the appearance of different types of agricultural products on display cannot be clarified.This study takes wet markets light environment as the research object,combines the field research studies and psychophysical experiments,explores the visual preferences of Chinese people for wet markets display light sources,in order to improve the quality of wet market lighting environment and enhance the experience and satisfaction of consumers.This study consists of two parts:the first part is to investigate the current situation of the light environment in the wet market,focusing on the study of the light environment of vegetables,fruits and fresh meat stores and comparing their differences.The research content mainly includes the lighting mode,light source type,light source correlated color temperature(CCT),general color development index and subjective evaluation of the light environment in the store space of the wet market.The results show that:different kinds of stores have great differences in light source correlated color temperature(CCT),and the subjective satisfaction of consumers is low.Due to the complex environment of the wet market and the differences between customers,it is impossible to
