AI Technical Summary
At some intersections with relatively small angles between roads, there is interference problem with the traffic lights located directly in front of the intersection and the traffic lights located on the side of the intersection, which may cause the driver to mistake the traffic lights on the side of the intersection for the traffic lights in front of the road, thus forming wrong guidance to the driver and posing certain safety hazards.
A light directional protection device for traffic lights is designed, which includes a lamp holder, a lamp board, a transparent lampshade, a light shield and a mounting piece, and an anti-peeping film is attached to the surface of the lampshade. By applying a layer of anti-peeping film outside the lampshade of the traffic light, the viewing angle of the light is controlled so that the light of the traffic light can only be clearly seen by the drivers at the intersection facing the traffic light, and the drivers at other intersections facing the traffic light cannot see the light of the traffic light.
Effectively prevent drivers from mistakenly identifying traffic lights, avoid traffic accidents caused by mistakenly identifying traffic lights, and improve road traffic safety.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0019] like Figure 1-3As shown, in the first embodiment of the light directional protection device of the traffic light of the utility model, the protection device 10 includes a lamp holder 11, a lamp board mounted on the lamp holder 11, a transparent lampshade 12 fixedly covered on the periphery of the lamp board, a light shielding cover 14 mounted on the lamp holder 11 and covering the periphery of the lamp board, and a mounting member 15 connected to the lamp holder 11, and an anti-peep film 13 is attached to the surface of the lampshade 12.
[0020] When the light directional protection device 10 of the traffic light of the utility model is used, a layer of anti-peep film 13 is attached to the outside of the lampshade 12 of the traffic light. The anti-peep film is made by using visual microcrystalline grid technology and can control the visible angle of light. That is, the light of the traffic light can only be clearly seen by drivers at the intersection facing the traffic light, while drivers at other intersections not facing the traffic light cannot see the light of the traffic light. This can prevent drivers from mistaking the traffic light for the traffic light and avoid traffic accidents caused by mistaking the traffic light for the traffic light.
[0021] Preferably, a plurality of LED lamp beads are evenly mounted on the lamp board, and the plurality of LED lamp beads are connected in parallel with each other.
[0022] like Figure 1 , 2 As shown, the mounting member 15 includes a first end plate 16 rotatably connected to the first end of the lamp holder 11, a second end plate 17 rotatably connected to the second end of the lamp holder 11, and a connecting plate 18 fixedly connecting the first end plate 16 and the second end plate 17. The first end plate 16 is rotatably connected to the first end of the lamp holder 11 via a first rotating shaft 20, and the second end plate 17 is rotatably connected to the second end of the lamp holder 11 via a second rotating shaft 21.
[0023] Furthermore, the connecting plate 18 is provided with a plurality of fixing holes 19 for fixing and installing the connecting plate 18 .
[0024] Furthermore, a first connecting hole 24 is provided on the first end plate 16 at a position different from the first rotating shaft 20, and a plurality of first threaded holes 25 are provided at a position of the first end of the lamp holder 11 corresponding to the first connecting hole 24. The protective device 10 also includes a first positioning bolt 22 that can pass through the first connecting hole 24 and be screwed to the first threaded hole 25.
[0025] A second connecting hole is provided on the second end plate 17 at a position different from the second rotating shaft 21, and a plurality of second threaded holes are provided at a position corresponding to the second connecting hole on the second end of the lamp holder 11. The protection device 10 also includes a second positioning bolt 23 that can pass through the second connecting hole and be screwed to the second threaded hole.
[0026] Further, such as Figure 3As shown, the plurality of first threaded holes 25 are arranged at equal intervals on a circle with the first rotating shaft 20 as the center and the distance between the first rotating shaft 20 and the first connecting hole 24 as the radius.
[0027] The plurality of second threaded holes are arranged at equal intervals on a circle with the second rotating shaft 21 as the center and the distance between the second rotating shaft 21 and the second connecting hole as the radius.
[0028] When installing and debugging the traffic light, the connecting plate 18 can be first fixed to the lamp post, and then the lamp holder 11 can be rotated around the first rotating shaft 20 and the second rotating shaft 21 until the traffic light on the lamp holder 11 is facing the indicated intersection, and then the first positioning bolt 22 is passed through the first connecting hole 24 and screwed into the first threaded hole 25, and the second positioning bolt 23 is passed through the second connecting hole and screwed into the second threaded hole to achieve fixed positioning of the lamp holder 11.
[0029] Compared with the prior art, the embodiment of the utility model attaches a layer of anti-peep film outside the lampshade of the traffic light, thereby effectively shielding interfering light other than the light directly in front of the traffic light, so that the light of the traffic light can only be clearly seen by drivers at the intersection directly facing the traffic light, while drivers at other intersections not directly facing the traffic light cannot see the light of the traffic light. This can prevent drivers from mistaking the traffic light for the traffic light and avoid traffic accidents caused by mistaking the traffic light for the traffic light.
