摘要： The present invention relates to a visual efficacy measuring method for objects in different light environments, which comprises: (a) setting a light environment; (b) measuring a relationship between color temperature and time; (c) a driver visually recognizing a target object; (d) resetting the light environment, and repeating the step (c); (e) processing the visual recognition information data collected by the experiments so as to establish a relationship of the visual recognition time in relation with the light environmental parameters of color temperature, color rendering index and brightness; (0 performing visual efficacy analysis according to the processing results of the visual recognition information data. The present invention also provides a color temperature standard determining method for a tunnel middle section in day time, which comprises: (a) setting a light environment; (b) measuring a relationship between color temperature and time; (c) selecting a stably distributed color temperature segment; (d) determining the color temperature standard. The method of the present invention performs visual efficacy analysis of the influence that light environment settings of illumination on a night road or in a tunnel middle section have on drivers' visual recognition activity, thereby providing a good guiding standard for reasonable and efficient setting of color temperature, color rendering index and average brightness of an illumination device.
