A STUDY ON THE EXPERIMENTAL METHOD FOR LANDSCAPE LIGHTING OF WEAK CONTRAST IN MESOPIC VISION

摘要

This paper introduces a kind of experimental method which can revert, simulate and evaluate thescene in the laboratory by researching the landscape lighting of the Chinese classical garden which is a typical scene in mesopic vision. Through experiment observation, computer simulation, and taking into account the environment characteristics, the method relates the quantitative index and the qualitative description by using subjective evaluation in laboratory. Through the statistical analysis of experimental result, it can be seen that the luminance and the luminance ratio will have an important effect on the landscape lighting environment. Through the experimental research, the satisfactory luminance ratio is approximately 2approx6, the best ratio is 2approx3 in the environments which is similar to the Chinese classical garden.
