Research On The Interior Light Design Based On Visual Characteristics

As a breakthrough point the visual characteristics and the visual psychology generating process were analyzed.The main content of this thesis is lighting quality objective evaluation standard and lighting design mathematical model.This research's goal is for the creation green, comfortable, the health interior lighting environment provides the quota design data.The main research contents and achievements are as follows:1 On the basis of Weber—Fechner's law and visual brightness theory, research lighting quality objective evaluation standard.2 This thesis make use of image processing to study the visual brightness changes in the law when the target brightness and background brightness changes. This rule be applied to museum lighting design. Obtains the lighting design data that can help historical relic's protection as well as offer the good visual environment.3 This thesis takes the Weber—Fechner's law as the basis, has established the mathematical model of visual comfort. Obtains the visual comfort's formulas and the curves in the four kinds of light environment. The results indicated that:this visual comfort's mathematical model can better reflect the objective laws of visual comfort. and can provide the quantitative theoretical basis for energy-efficient lighting design.4 Based on the mathematical model which visual comfort level along with degree of illumination change,the illumination computation's analysis formula of green lighting design are established and applies this analysis formula in the degree of illumination design, then the green lighting illumination range is calculated under the several kind of light environment. This analysis formula is simple and brief, the variable value gain convenience. This is a broad new method to practical in green lighting.
