On a sunny day, the illuminance in front of the highway tunnel entrance is as high as tens of thousands of lux, while the tunnel lighting is generally only about 100 lux. At this time, when the driver enters the tunnel, the eyes will have about 10s of visual impairment. The phenomenon that the driver feels that the cave is so dark that he cannot recognize the obstacles in the cave is called the "black hole effect", which will easily cause traffic accidents
Existing tunnel lights uniformly illuminate the entire tunnel and are prone to black hole effects

The invention provides an irradiation angle and lighting state adjustable tunnel lamp as well as a tunnel lamp system and a working method. The signal transmitting end of a brightness sensor is connected with the signal receiving end of a central processing unit; an infrared signal is transmitted by a signal transmitter to detect a vehicle running speed; the signal transmitted by the transmitter is received by a signal receiver; the signal output end of the signal receiver is connected with the signal input end of a central controller; the signal output end of the central controller is connected with the signal receiving end of a driving control module; and the driving signal output end of the driving control module is connected with the signal receiving end of the tunnel lamp. The brightness sensor is mounted outside a tunnel, and the lighting brightness of the tunnel lamp at an exit / entrance of the tunnel is regulated through the input of the sensor; and a set of induction system is additionally arranged inside the tunnel lamp to induce a traffic accident, and the irradiation state of the tunnel lamp is changed when the traffic accident happens in the tunnel.
Description
technical field [0001] The invention relates to the field of mechatronics control, in particular to a tunnel light with adjustable irradiation angle and lighting state, a tunnel light system and a working method. Background technique [0002] Existing tunnel lights include a lamp body with a radiator and a connecting seat for fixing the lamp body. The tunnel lamp is fixed on the fixed plate or wall of the tunnel through the connecting seat. The angle of the fixed tunnel lamp cannot be adjusted, and the light is scattered Distributed in the tunnel, the scattered light is not strengthened at the positions that are easy to be recognized by the human eye, such as the license plate, so that the driver cannot accurately judge the position and speed of the vehicle in front, which is likely to cause traffic accidents. [0003] When the human eye stays in a place with sufficient light for a period of time, when entering a dark room, the visual sensitivity suddenly decreases, and then...
