Description

Technical Field

[0001] The utility model relates to a tunnel lighting technology, in particular to a tunnel entrance dimming system which dynamically adjusts the length of a shed hole based on external brightness. Background Art

[0002] The "black hole effect" at the entrance of a tunnel refers to the inability of the driver's visual system to quickly adapt to the change in brightness when entering a relatively dark tunnel from a bright external environment during the day when the sun is strong, resulting in temporary loss of vision or blurring of vision. This phenomenon greatly increases the risk of driving, especially in highway tunnels, where drivers may not be able to react in time if they cannot quickly adjust their vision, thus causing traffic accidents.

[0003] Traditional tunnel entrance lighting methods include alleviating this light difference through artificial lighting or shed structures. However, fixed-length sheds are usually difficult to cope with light changes in different time periods or weather conditions. For example, at noon or when the sun is strongest, the fixed shed length may not provide enough light buffer, and drivers will still feel that the contrast between light and dark is too large when entering the tunnel, resulting in a black hole effect. On the other hand, when the sun is weak, the fixed shed may unnecessarily block natural light, making the tunnel entrance too dim and not conducive to driving safety.

[0004] Therefore, there is an urgent need to develop a tunnel entrance dimming shed system that can dynamically adjust the length of the shed according to the external brightness. The length of the shed can be dynamically adjusted according to changes in external brightness, especially the intensity of daytime light, to effectively reduce the black hole effect at the tunnel entrance. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a tunnel entrance dynamic adjustment dimming shed system to alleviate the brightness difference between the inside and outside of the tunnel and enhance driving safety.

[0006] The utility model discloses a tunnel opening dynamic adjustment light reduction shed system, which comprises a plurality of movable frames arranged along the road direction and flexible light reduction films evenly laid on the movable frames, wherein the flexible light reduction films have a set foldable property and can be folded along with the telescopic movement of the movable frames.

[0007] Furthermore, the movable frame is laid on the guide rail of the road outside the tunnel entrance, and the guide rail extends along the tunnel pavement direction. A guide rail is provided on each side of the road. The movable frame near the tunnel entrance is fixed to the tunnel entrance, and the length of the light-reducing shed hole can be slidably adjusted on the guide rail as needed.

[0008] Further, the movable frame includes guide wheels, a base, diagonal braces, and a flexible light-reducing film bracket, and also includes a hinge installed between adjacent movable frames. The length of the hinge is slightly greater than the maximum extension length of the flexible light-reducing film laid between adjacent movable frames.

[0009] Further, the movable frame further includes a driving device located on the base of the first movable frame. The driving device drives the first movable frame to move along the guide rail, and the first movable frame drives the remaining movable frames to move through the hinge, thereby changing the extension length of the light-reducing shed opening.

[0010] Further, a light intensity measuring device is provided on the road surface below the light-reducing shed opening. The light intensity measuring device is installed below the road surface line, and the photosensitive surface of the light intensity measuring device is flush with the road surface line.

[0011] Further, the light intensity measuring device is used to collect the light intensity and transmit the data to the control system.

[0012] Further, the light-reducing shed opening further includes a control system. The control system receives the data from the light intensity measuring device and analyzes it, and controls the driving device according to the analysis result to further control the expansion and contraction of the light-reducing shed opening.

[0013] Further, the flexible light-reducing film has the characteristic of weakening the light intensity, and can form a continuous light-reducing area when the light-reducing shed opening is unfolded, so as to buffer the brightness difference between the external light and the darker environment inside the tunnel.

[0014] The beneficial effects of the present utility model: The dynamic adjustment light-reducing shed opening system at the tunnel entrance of the present utility model, through the design of the guide rail system and the movable frame, and using the flexible light-reducing film as the main material of the light-reducing shed opening, enables the length of the light-reducing shed opening to be flexibly adjusted according to the light intensity of the external environment, forming a continuous light-reducing area, thereby providing sufficient brightness buffer when the sun is strong, reducing the occurrence of the black hole effect, and ensuring the safety of tunnel traffic.
