蔬果照明光源与物体的照明光谱反射关系研究

Study on the Relation between Vegetable and Fruit Illumination Light Source and Object Illumination Spectrum Reflection

目前大型超市的蔬果、鲜肉照明能满足基本的照明需求,但缺乏理论研究,鲜有对光源光谱与被照物光谱反射关系的实验,蔬果、鲜肉照明效果不能得到优化。通过比对仿真蔬果在高低两种色温的多个同色异谱光源下的呈现效果,对蔬果反射曲线与光源光谱关系进行分析研究,讨论光源色与物体色之间的相互作用。基于物体色选取预期的光源光谱,调配合适的光源光谱应用于蔬果照明,有利于超市照明定型化、定量化发展,优化超市照明光源选用。

At present,the current lighting situation of fresh meat of vegetables and fruits in large supermarkets in China can meet the basic lighting needs,and improve the saturation of illuminated goods to increase purchasing desire,but there is no theoretical research,and there are few experiments on the reflection relationship between light source spectrum and illuminated object spectrum.The lighting effect of fresh meat of vegetables and fruits can not be optimized by comparing the simulation of multiple homogeneous and heterogeneous light sources of vegetables and fruits at high and low color temperatures.The relationship between vegetable and fruit reflectance curve and light source spectrum is analyzed and studied.The interaction between light source color and object color is discussed.This research chooses the expected light source spectrum based on object color and applies it to vegetable and fruit lighting by adjusting the light source spectrum.It is beneficial to the development of supermarket lighting towards stereotyping and quantification,and optimizes the selection of lighting source in supermarket.
