A kind of vehicle tunnel safe driving lighting system and lighting control method

Abstract

A lighting system for safe driving in a car tunnel, comprising an entrance speed measuring radar and a tunnel speed measuring radar, the entrance speed measuring radar and the tunnel speed measuring radar are respectively electrically connected to an input terminal group of a controller, and the output terminal of the controller is connected to the input terminal of a lighting control circuit, The output end group of the lighting control circuit is connected with a group of lighting lamps in turn. The speed measuring radar at the entrance detects the vehicle in front of the tunnel entrance, and controls the lighting in the tunnel through the controller. The speed measuring radar is used to detect whether there is a vehicle in the tunnel or not. When the tunnel entrance speed radar detects that there is a vehicle in front of the tunnel entrance, all the lights in the tunnel will be turned on, and the first 10 lights at the tunnel entrance will be controlled to be the brightness of other lights. 3 times or even more times of that, which is beneficial for the driver to avoid traffic accidents when entering the tunnel due to the darkened eyes caused by brightness changes and unable to see the road conditions clearly.

Description

technical field [0001] The invention relates to the technical field of lighting technology, in particular to a lighting system and a lighting control method for safe driving in an automobile tunnel. Background technique [0002] At present, high-power lighting lamps are widely used for driving lighting in tunnels, and 24-hour lighting consumes a lot of energy. [0003] Chinese patent, titled Highway Tunnel Lighting Intelligent Control System, the patent number is: CN201320287934.9, the patent discloses an energy-saving lighting method, but the method has the following problems: when the light outside the tunnel is strong, the driver enters In the tunnel, it is easy to cause darkness in front of the eyes, and it is difficult to see the situation in the tunnel clearly, and the safety problem of tunnel lighting cannot be well solved. Chinese patent, the application number is: 201310125219.X, the name is a kind of road tunnel lighting system and its lighting method, adopts the ...

Problems solved by technology

[0003] Chinese patent, titled Highway Tunnel Lighting Intelligent Control System, the patent number is: CN201320287934.9, the patent discloses an energy-saving lighting method, but the method has the following problems: when the light outside the tunnel is strong, the driver enters Tunnel, it is easy to cause blackness in front of the eyes, and it is difficult to see the situation in the tunnel clearly, and it cannot solve the safety problem of tunnel lighting well.

By physically installing the device, there is undoubtedly a costly problem

The patent application number is 201020571536.6, and the name is a tunnel lighting system with light-sensing automatic control brightness mode. It can only solve the lighting problem according to the weather conditions, but it cannot solve the problem of power failure and energy saving when there is no car.
