Abstract

The invention discloses a method for selecting a tunnel entrance section illumination light source based on driver visual adaptation. The method comprises the steps: measuring and recording light color data of sunlight outside a tunnel of different types within 24 h in one day; measuring and recording light color data of sunlight outside the tunnel under different weather conditions of the same tunnel; selecting tunnel lighting LED light sources with different light colors universal in the market; measuring and recording dark adaptation time data when a driver enters an entrance section for providing illumination by the LED light sources with different light colors when the light color of the sunlight is not changed; analyzing the measurement data, and determining the light color of the LED light source for providing illumination at the entrance section when the dark adaptation time of the driver is the shortest; and establishing a relation model of the tunnel external natural light color and the tunnel entrance lighting lamp light color. According to the invention, the light color of the LED light source most suitable for tunnel entrance illumination can be selected according to the light color data of sunlight in different time periods outside the tunnel, and the dark adaptation time of a driver can be reduced, and intelligent support is provided for tunnel illumination safety.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting, in particular to a method for selecting a lighting source for a tunnel entrance section based on driver's visual adaptation. Background technique [0002] The highway tunnel lighting system is an important guarantee to ensure the safe passage of vehicles. Different from general road lighting, the interior of the tunnel also needs to be illuminated during the day, and the lighting problems inside the tunnel are more complicated during the day. After the driver enters the tunnel during the day, the internal brightness suddenly decreases, and he has to adapt for a period of time to distinguish the internal situation of the tunnel, which is called "adaptation lag phenomenon". This kind of phenomenon that people's visual senses cannot adapt quickly due to the sharp change of ambient brightness is called "dark adaptation", and this process takes a long time. In order to enable drivers to adapt...
