Background

When the natural light environment outside the tunnel enters the artificial light environment inside the tunnel, the brightness of the light environment inside the tunnel is far lower than that outside the tunnel, so that the driver is difficult to identify objects inside the tunnel outside the tunnel, namely the so-called 'black hole effect' occurs. The 'black hole effect' reduces the driving safety of the tunnel section, so the reduction of the 'black hole effect' is an important target of the illumination design of the highway tunnel.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-4, an entrance section lighting system for weakening black hole effect of a highway tunnel comprises a solar energy collecting device, a vehicle information collecting device, an environment information collecting device and a reinforced lighting device arranged at the entrance section of the tunnel, wherein the solar energy collecting device, the vehicle information collecting device, the environment information collecting device and the reinforced lighting device are arranged outside the tunnel entrance, the reinforced lighting device comprises at least two groups of arc steel frames, each group of arc steel frames comprises two arc steel frames which are annularly and symmetrically arranged along the side wall of the tunnel, a group of reinforced lighting lamps are annularly arranged on each arc steel frame, each reinforced lighting lamp is sleeved with a cylindrical lampshade which is used for limiting a light beam and enabling the light beam to point to the center of a traffic lane, and all the reinforced. The shading in fig. 1 is the bright light range produced by the ring-shaped luminaire. In fig. 3, Ds is the parking sight distance, I is the distance from the boundary line of sunlight in the hole to the hole opening, and the shadow in fig. 4 is the bright light range generated by reflected sunlight.

The solar energy collecting device is any one of a solar light reflector, a solar cell or a light guide. The vehicle information acquisition device is arranged at a parking sight distance between the tunnel entrance and the tunnel outside distance entrance and is connected with the lamp controller through a line; the environment information acquisition device is arranged in a 20m range in the tunnel and at a parking sight distance outside the tunnel, acquires the brightness inside and outside the tunnel, and is connected with the lamp controller through a circuit. And the lighting controller controls the running time and the quantity of the tunnel lamps through the speed of the vehicle and the brightness inside and outside the tunnel.

The reinforced lighting lamp is annularly arranged on the arc steel frame on the side wall of the tunnel at intervals, the cylindrical lamp covers matched with each group of lamps limit the light beam emission direction, the light beams point to the center of the lane, and the lamp installation angles are different due to different erection heights of the lamps, but the axis of the lamp after installation points to the center line of the lane.

In practical application, the reinforced illumination of the entrance section from the tunnel entrance to 20m in the entrance cannot obviously reduce the black hole effect because the reinforced illumination is arranged along the depth of the tunnel, the front 20m of the entrance section is not linearly arranged along the depth of the tunnel but annularly arranged along the cross section of a certain tunnel, and the light beam projection direction is restrained by the lampshade, so that vehicles within the range of 20m in the entrance are irradiated by the light beam, the contrast between the vehicles in the hole and the dark environment of the tunnel is improved, the black hole effect is finally weakened, and the driving safety is improved.
