Abstract

The invention provides an alertness-considered non-visual optical biological effect evaluation method used in the mesopic vision category. The alertness-considered non-visual optical biological effectevaluation method comprises the following steps: S1, constructing a mesopic vision spectral optical visual efficiency calculation model and a non-visual optical biological effect model; S2, calculating an intermediate vision effect value and a non-vision optical biological effect value based on the intermediate vision spectrum optical visual efficiency calculation model and the non-vision opticalbiological effect model; calculating the ratio of the non-visual photo-biological effect value to the mesopic visual effect value; and S3, according to the light source brightness and spectrum of theactual lighting environment, selecting a lighting source by utilizing the ratio of the non-visual light biological effect value to the mesopic visual effect value and combining the degree of need ofthe lighting environment for alertness. From the perspective of the photobiological effect, the spectral composition capable of improving the alertness of a driver is studied, so that a safe and comfortable lighting environment is provided for highway tunnel traffic, and meanwhile, a theoretical basis is provided for formulating tunnel lighting rules in the future.

Description

technical field [0001] The invention relates to the technical fields of mesovision and road lighting, in particular to a method for evaluating non-visual photobiological effects in the category of mesovision considering alertness. Background technique [0002] Fatigue and drowsiness are one of the leading causes of driving accidents. According to the survey, up to 90,000 people in China are killed or seriously injured in accidents related to fatigue driving every year, and the serious traffic accidents caused by fatigue driving are as high as 40%. Due to the semi-enclosed space characteristics of highway tunnels, its visual oppression and monotonous environment are more likely to aggravate the driver's fatigue and irritability, resulting in decreased driver alertness, inattention and decreased performance. When the driver drives the vehicle through the interior of the tunnel, there is no natural light to provide illumination, and he can only rely on the lighting fixtures in...
