Extra-long tunnel middle section illumination light environment color temperature setting method based on driving safety and comfort

Abstract

The invention discloses an extra-long tunnel middle section illumination light environment color temperature setting method based on driving safety and comfort, and belongs to the technical field of highway tunnel illumination. According to the method, the requirement of a driver for color temperature when the driver drives in the middle section of the extra-long tunnel is researched according to the influence of natural circadian rhythm of a human body and color temperature on visual efficacy and non-visual light biological effect of human eyes, and the illumination light environment color temperature setting method for the middle section of the extra-long tunnel, which meets the safe and comfortable driving requirement of the driver, is provided. According to the arrangement method, the effect of the LED light source is fully exerted, and the requirement for safe and comfortable driving of a driver in an extra-long tunnel is met.

Description

technical field [0001] The invention relates to a method for setting the color temperature of an illumination light environment in the middle section of an extra-long highway tunnel, and belongs to the technical field of highway tunnel lighting. Background technique [0002] Because LED light sources have the advantages of short response time, high energy efficiency, and adjustable color temperature, which can simulate natural light, they are increasingly used in road tunnel lighting. However, at this stage, there is no relevant standard basis and systematic and comprehensive theory and technology for the color temperature of the lighting source characteristics in the middle section of the extra-long highway tunnel. The selected color temperature ranges from 3000-6500K and is a fixed value for all weathers. This color temperature setting method has technical defects such as low color temperature, easy to cause driving fatigue at night, high color temperature to cause glare, ...

AI Technical Summary

Problems solved by technology

Relevant researchers found that the color temperature in the mesoscopic environment in the middle of the tunnel can affect the light and color sensitivity of the human eye and the ability to recognize the details and colors of the target, thereby affecting the visual performance of the human eye

Domestic and foreign studies on the selection of color temperature in highway tunnels lack the consideration of changes in the circadian rhythm of the human body. The color temperature is set to the same value during the day and night, which will affect the efficiency of visual recognition and driving comfort in the middle section of the tunnel.
