Detailed Description

The utility model will be described in further detail with reference to the drawings and the specific embodiments.

In the same tunnel, the illumination conditions of the tunnel entrance and the tunnel exit are different, and the natural illumination area and the illumination intensity of the tunnel entrance are different in the natural illumination state. When a vehicle enters the tunnel from the outside of the tunnel, the illumination intensity at the entrance of the tunnel is far lower than the intensity outside the tunnel, and the transition area of the light intensity is smaller. At this time, the driver will feel that the light 23 is changed from bright to dim instantaneously, and the vision system is not adjusted in time, so that the driver has a 'faint' feel. On the contrary, when the vehicle exits from the tunnel, the illumination intensity inside the tunnel is far lower than the illumination intensity outside the tunnel, and the driver can feel that the light 23 is instantaneously changed from dark to bright, and the vision system is not adjusted in time, so that the driver has a dazzle feel. Both visual perceptions lead to serious traffic accidents for vehicles traveling at high speeds.

At present, a common mode for illuminating a tunnel entrance and a tunnel interior is a method adopting lamplight illumination. The main problem of the method is that the illumination requirements and environmental factors of the tunnel entrance and the tunnel interior are greatly changed, and the illumination reliability is often not high. And the degree of automation is overall lower, and uninterrupted consumption of a large amount of electric energy is required. In addition, the tunnel area is longer, the influence of the environment of the current area of the tunnel is larger, and the requirements on the light intensity are different. The lighting devices at the tunnel entrance and the tunnel inside lack of differential treatment, which results in low light supplementing effect inside and outside the tunnel, so that the basic function of adjusting the lighting intensity difference requirements inside and outside the tunnel is lost.

In order to solve the above-mentioned problems, there is a problem in terms of the requirement for the difference in illumination intensity at the tunnel entrance and exit. According to the natural conditions of the area where the tunnel is located, the utility model adopts a clean energy linkage energy storage mode of abundant solar energy, wind energy and the like outside the tunnel to provide direct or indirect clean energy for the light supplementing device 4 at the tunnel entrance and exit, thereby developing a set of automatic control system and device for light supplementing and dizziness preventing at the tunnel entrance and exit based on the clean energy.

Furthermore, on one hand, clean energy such as solar energy, wind energy and the like is adopted to generate electricity, and electric energy support is provided for the light supplementing device 4; on the other hand, a light guide system is adopted to transmit a light source outside the tunnel to the tunnel entrance through an optical medium to perform a direct light supplementing function. Besides adopting an external light source to directly supplement light at the tunnel entrance, the LED lamp strip 24 can also be used for illuminating and supplementing light. Light supplementing characteristics at tunnel entrance: the illumination intensity of the light supplementing device 4 is gradually changed from strong to weak from strong until the illumination intensity approaches to the illumination intensity of the light in the tunnel. And, the diameter of the light filling lamp at the entrance of the tunnel gradually becomes smaller from large. Light supplementing characteristics at tunnel exit: the light supplementing device 4 changes the intensity of illumination from inside to outside gradually from weak to strong until the intensity of illumination approaches to the intensity of illumination of natural illumination outside the tunnel. And the diameter of the light supplementing lamp at the tunnel outlet gradually increases from small to large. The function of the tunnel entrance light supplementing device 4 is to gradually enlarge the transition area of the illumination intensity inside and outside the tunnel, reduce the illumination intensity difference inside and outside the tunnel entrance, keep the adjustment time for the vision system as long as possible, reduce the probability of the occurrence of the phenomena of 'dark halo' and 'glaring', and ensure the driving safety at the tunnel entrance.

The light supplementing device 4 at the outlet of the tunnel gradually increases the illumination intensity from inside to outside until the illumination intensity approaches the natural illumination intensity outside the tunnel. The main purpose of the light supplementing device 4 is to reduce the illumination intensity difference at the entrance and the exit of the tunnel and increase the transition area of the illumination intensity.

When the illumination intensity and light intensity sensor at the entrance and exit of the tunnel detects that the illumination intensity of the area is higher than the system set value, the opening degree of the light isolation film 27 on the outer cover of the illuminator 20 is reduced, and the exposure of the light guide medium 26 is reduced, so that the illumination intensity of the area is weakened. When the light intensity sensor at the tunnel entrance detects that the current illumination intensity is lower than the system set value, the opening degree of the light isolation film 27 on the outer cover of the illuminator 20 is increased, and the exposure of the light guide medium 26 is increased, so that the illumination intensity of the area is enhanced. If the light supplementing effect of the light emitter 20 does not reach the system set value, the LED lamp strip 24 at the outer ring of the light emitter 20 is electrified to emit light at the moment, so that auxiliary light supplementing is performed.

A plurality of groups of convex lenses 15 are arranged on the condensing frame 16 in an array to form a lighting device, and the positions of each convex lens 15 are dispersed on the end face of the condensing frame 16 so that light rays 23 are focused on the focus A of the concave lens 22. In order to increase the condensing effect, a layer of total reflection film 21 is wrapped on the inner surface of the condensing frame 16. The whole lighting device is connected to the light pipe 19 by adopting the spherical joint 17, so that the direction of the end face of the lighting device can be conveniently adjusted, and the lighting device can conveniently collect natural light. Further, a plurality of light emitters 20 having different diameters are mounted on the light guide 19 to directly light the light source lamp.
