[0003] With the development of urban construction, in order to improve the safety of pedestrians crossing crosswalks, some newly built urban areas are considering installing embedded ground traffic lights along zebra crossings. Specifically, the principle of embedded ground traffic lights is to use light panels to emit light and send signals to pedestrians or vehicles outside, or to play a role in auxiliary lighting in some scenarios. Their top is flush with the road surface and does not affect the passage of vehicles and pedestrians.
[0004] Existing embedded ground traffic lights illuminate the sky using light panels, providing a clear and immediate display for pedestrians at close range. However, drivers of vehicles at greater distances may have difficulty receiving the signal due to angle and other factors.
[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0006] The purpose of this invention is to provide an embedded ground traffic light that can guide part of the light in an oblique direction through a light guide plate set on the lighting device, thereby improving the driver's reception of the signal.
[0007] To achieve the above objectives, this utility model discloses an embedded ground traffic light, which includes:
[0008] A bottom shell having a top end and a bottom end oppositely disposed therefrom, the bottom shell being used to be embedded in the road surface;
[0009] A lighting device, comprising a lamp panel and a control line, wherein the lamp panel is installed in the bottom shell, the output end of the lamp panel is arranged facing the top of the bottom shell, one end of the control line is electrically connected to the lamp panel, and the other end of the control line passes through the bottom shell and extends to the main lighting control.
[0010] A light guide plate is installed in the bottom shell. The light guide plate includes a body and a light guide part. The body covers the top of the lamp plate and is connected to the body. The light guide part is located on one side of the top of the body and has an inclined surface that is not parallel to the body.
[0011] As a further description of the above technical solution, the embedded ground traffic light also includes a top cover, which is disposed on the top of the bottom shell, and there is a preset gap between the top cover and the top of the light guide plate body.
[0012] As a further description of the above technical solution, the vertical height of the light guide is equal to the height of the preset gap.
[0013] As a further description of the above technical solution, the inclined surface of the light guide has ribs arranged at intervals.
[0014] As a further description of the above technical solution, the light guide portion is disposed near the edge of the light guide plate body, and the side of the light guide portion with the inclined surface is disposed in a direction away from the light guide plate body.
[0015] As a further description of the above technical solution, the number of light guides is set to multiple.
[0016] As a further description of the above technical solution, the number of light guides is six, and the six light guides are arranged in groups of three, with two groups of light guides mirror-image arranged on both sides of the light guide plate along the center of the light guide plate.
[0017] As a further description of the above technical solution, the line connecting the two sets of light guides is parallel to the extension direction of the motor vehicle lane, and the line connecting the two sets of light guides is perpendicular to the extension direction of the pedestrian crossing.
[0018] Based on the above technical solution, the beneficial effects of this utility model are as follows:
[0019] This utility model discloses an embedded ground traffic light. By using a light guide plate on the lighting device, a portion of the light is guided at an angle, improving the driver's signal reception. Specifically, the output end of the lamp panel faces upwards, with its LEDs illuminating directly upwards towards the light guide plate. The horizontally covering light guide plate allows pedestrians at a distance to clearly see the flashing signal. Part of the light is diverted by the light guide portion on the light guide plate, illuminating one side of the angled surface, which is then oriented towards the driver, further enhancing the driver's signal reception. The light guide plate installation structure is stable and low-cost, effectively solving the problem of insufficient brightness for driver signal alerts.

[0031] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.
[0032] Please see Figure 1-2 This embodiment provides an embedded ground traffic light, which includes:
[0033] The bottom shell 1 has a top end and a bottom end that are disposed opposite to each other, and the bottom shell 1 is used to be embedded in the road surface;
[0034] Lighting device 2 includes a lamp panel 21 and a control line 22. The lamp panel 21 is installed in the bottom shell 1, and the output end of the lamp panel 21 is set towards the top of the bottom shell 1. One end of the control line 22 is electrically connected to the lamp panel 21, and the other end of the control line 22 passes through the bottom shell 1 and extends to the main lighting control.
[0035] The light guide plate 3 is installed in the bottom shell 1. The light guide plate 3 includes a body 31 and a light guide part 32. The body 31 is disposed covering the top of the lamp plate 21. The light guide part 32 is connected to the body 31 and disposed on one side of the top of the body 31. The light guide part 32 has a slope 321 that is not parallel to the body 31 and is raised.
[0036] For the above structure, during installation, first prepare the base shell 1 of the corresponding size, and then pass the control wire 22 of the lighting device 2 through the base shell to the corresponding position. This can be done from the side wall of the base shell 1 (e.g., Figure 1 As shown), or it can be inserted into the bottom of the bottom shell 1 through the bottom position, and after connecting the light plate 21, the light plate 21 is installed parallel to the bottom position of the bottom shell 1. Then, a light guide plate 3 is covered on the top of the light plate 21, so that the body 31 of the light guide plate 3 is parallel to the main body of the light plate 21 in the horizontal direction. In this embodiment, it can be parallel to the ground horizon. Then the embedded ground traffic light is sealed and adjusted.
[0037] With the above structure, during use, the control line 22, under the control of the main lighting control, supplies power to the lamp panel 21 of the lighting device 2 and controls it to emit signals. The lamp panel 21 illuminates upwards, and most of the light, after passing through the horizontally placed body 31 of the light guide plate 3, is dispersed towards the top of the embedded ground traffic light, so that pedestrians near the embedded ground traffic light can directly receive the light signal guided and dispersed by the body 31 of the light guide plate 3. At the same time, a light guide part 32 is installed above the body 31. The light guide part 32 is materially connected to the body 31. At least part of the light passes upwards through the body 31 of the light guide plate 3 and then through the light guide part 32. Under the guidance of the light guide part 32, at least part of the light is emitted from the inclined surface 321 of the light guide part 32.
[0038] like Figure 1 As shown, due to the tilt angle of the inclined surface 321, the light emitted from the inclined surface 321 of the light guide 32 can illuminate the motor vehicle lane at a greater distance. Therefore, it is easier for drivers in vehicles at a greater distance to receive the light signal from the light guide plate 3 more clearly.
[0039] In the above embodiments, a light guide plate 3 installed on the lighting device 2 can guide some light in an oblique direction using the light guide portion 32, thereby improving the driver's signal reception. Specifically, the output end of the lamp plate 21 of the lighting device 2 is positioned facing upwards, and the lamp beads on it illuminate directly upwards towards the light guide plate 3. The horizontally covering light guide plate 3 body 31 allows pedestrians at a distance from the embedded traffic light to visually observe the flashing signal. Part of the light is diverted by the light guide portion 32 on the light guide plate 3 body 31, illuminating one side of the oblique surface 321 of the light guide portion 32, which is then positioned towards the driver, improving the driver's signal reception of the embedded traffic light. The installation structure of the light guide plate 3 is stable and low-cost, effectively solving the problem of insufficient brightness for driver signal reminders.
[0040] Specifically, such as Figure 2As shown, the lighting device 2 in this embodiment has a lamp plate 21 with spaced-out lamp beads. The lamp plate 21 has a sufficiently large coverage area, so that the body 31 of the light guide plate 3 and the light guide part 32 can receive a large amount of light input and output the light accordingly.
[0041] The embedded ground traffic light also includes a top cover 4, which is placed on top of the bottom shell 1. There is a preset gap between the top cover 4 and the top of the light guide plate 3. During installation, the gap at the bottom of the top cover 4 can be filled with glue to achieve a better sealing effect on the light guide plate 3 and the lighting device 2 at the bottom, preventing liquid leakage and short circuits during outdoor use.
[0042] Furthermore, based on the above structure, the vertical height of the light guide 32 is equal to the height of the preset gap. The aforementioned height refers to the vertical height from top to bottom. In this structure, the height of the light guide 32 can be maximized, so that after it guides the light, the coverage angle can be wider.
[0043] In this embodiment, the inclined surface 321 of the light guide 3 has spaced-apart ribs 322. The ribs 322 extend along the short side of the inclined surface 321 and are spaced-apart along the long side of the inclined surface 321. The structure of the ribs 322 itself can simulate a diffuse reflection effect, increase the richness of the angle of light output of the inclined surface 321 of the light guide 32, and maximize the visibility of the driver from multiple angles at a distance.
[0044] The light guide portion 32 is disposed near the edge of the light guide plate 3 body, and the side of the light guide portion 32 with the bevel is disposed in a direction away from the light guide plate 3 body 31. Therefore, the light guide portion 32 itself can be avoided from being blocked by the surrounding ground or top cover 4 and the angle range of light venting can be maximized.
[0045] In this embodiment, the number of light guide portions 32 is set to multiple. For example... Figure 2 As shown, there are six light guide sections 32, arranged in groups of three. Two groups of light guide sections 32 are mirror images of each other on both sides of the light guide plate 3. The line connecting the two groups of light guide sections 32 is parallel to the extension direction of the motor vehicle lane, and perpendicular to the extension direction of the pedestrian crossing. In current use, the main function of the light guide sections 32 is to provide signal prompts to drivers in the motor vehicle lane. Therefore, by limiting the direction of the light guide sections 32, drivers in the motor vehicle lane can clearly receive the light from the light guide sections 32 in most cases. Since the inclined surface 321 of the light guide section 32 is perpendicular to the pedestrian crossing, pedestrians receive less light from the inclined surface 321. Through reasonable light transmission and distribution, visual pollution to pedestrians is avoided, and drivers at a distance are effectively alerted.
