The Research on Quantificational Method of Chromatic-Light Emotion in Automotive Interior Lighting

Abstract

With the development of new lighting technologies, automotive interior ambient light extends from basic Illumination function to comfort and personalization function. However, the application of ambient lamp light lacks theoretical support and scientific quantitative basis, and has great blindness and randomness. How to use the emotion and preference aroused by chromatic-light scientifically is the key to solve the above problems. In the experiment, 12 chromatic-light stimuli were output with chroma and hue as variables. The emotions aroused by light were quantitatively studied by experimental psychological methods. By factor analysis, we obtained three monochrome affective factors: activity, evaluation and adaptability. In the correlation analysis of the influence of chromatic-light attributes on emotion, it was found that the chroma had the greatest influence on chromatic-light emotion, followed by the hue of chromatic-light. By analyzing the preference of chromatic-light, we find that yellow light is preferred.
