[0003] The utility model aims to provide a traffic sign to solve the problem that the existing prompt function is relatively weak.
[0004] To achieve this purpose, the utility model adopts the following technical solutions:
[0005] A traffic sign, characterized by comprising a back plate layer, a semi-transparent surface identification layer, a first light strip, and a second light strip having a different light color from the first light strip;
[0006] The front side of the backplane layer has an annular groove, the first light strip and the second light strip are both installed in the annular groove, the surface identification layer is stacked on the front side of the backplane layer, the second light strip irradiates toward the inner periphery of the backplane layer to form a first illumination area on the surface identification layer; the first light strip irradiates toward the outer periphery of the backplane layer to form a second illumination area on the surface identification layer.
[0007] In one embodiment, the surface marking layer includes a semi-transparent key marking area and a light-transmitting area surrounding the key marking area;
[0008] The key identification area is located in the first illumination area; the light-transmitting area is located in the second illumination area; the light transmittance of the light-transmitting area is S1, and the light transmittance of the key identification area is S2, wherein S1>S2.
[0009] In one embodiment, the surface identification layer further includes an edge area arranged at the periphery of the light-transmitting area, and the light transmittance of the edge area is S3, wherein S3 <S2<S1。
[0010] In one embodiment, the edge area is a light-proof area.
[0011] In one embodiment, a filter layer is further included, and the surface identification layer is stacked on a side of the filter layer away from the back plate layer.
[0012] In one embodiment, the back plate layer includes a first protruding member and a second protruding member located outside the first protruding member, and the first protruding member and the second protruding member enclose the annular groove;
[0013] The first light strip is located inside the annular groove, connected to the first protrusion, and irradiates in the direction of the second protrusion; the second light strip is located inside the annular groove, connected to the second protrusion, and irradiates in the direction of the first protrusion.

DETAILED DESCRIPTION
[0024] In order to make the technical purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.
[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0027] In actual use, existing traffic signs require drivers or pedestrians to actively look for them. However, if the driver drives too fast or the road environment is dark, the specific content of the traffic sign cannot be observed in time, resulting in greater traffic risks.
[0028] The embodiment of the utility model provides a traffic sign 100, which is intended to solve the problem that the traffic sign cannot be observed in time when the vehicle is traveling too fast or the road environment is dark.
[0029] See also Figure 1 and Figure 3 The traffic sign 100 comprises a back plate layer 120, a semi-transparent surface identification layer 150, a first light strip 130, and a second light strip 140 having a different light color from the first light strip 130;
[0030] The front side of the backplane layer 120 has an annular groove 120a, the second light strip 140 and the first light strip 130 are both installed in the annular groove 120a, the surface identification layer 150 is stacked on the front side of the backplane layer 120, the second light strip 140 irradiates toward the inner periphery of the backplane layer 120 to form a first illumination area on the surface identification layer 150; the first light strip 130 irradiates toward the outer periphery of the backplane layer 120 to form a second illumination area on the surface identification layer 150.
[0031] It can be understood that when the traffic sign located on the surface of the first illumination area needs a strong reminder, the second light strip 140 works; when the traffic sign on the surface of the first illumination area does not need a strong reminder, the first light strip 130 works. Therefore, the second light strip 140 and the first light strip 130 have different light colors and light-emitting areas, which greatly improves the visual appeal and visual difference of the traffic sign 100, so that drivers or pedestrians can accurately and quickly observe the traffic sign. Specifically, when the second light strip 140 works, the first illumination area can illuminate the traffic sign and serve as a backlight source for the traffic sign to play a warning role; when the first light strip 130 works, the second illumination area can illuminate the periphery of the traffic sign, but does not serve as a backlight source for the traffic sign. At this time, the first light strip 130 works only as a reminder of the sign. Therefore, the design of the traffic sign 100 of the technical solution of the utility model solves the problem that the traffic sign cannot be observed in time when the vehicle is driving too fast or the road environment is dark, and improves the reminder ability of the traffic sign 100.
[0032] See also Figure 1 and Figure 2 In one embodiment, taking the zebra crossing traffic sign 100 as an example, when the zebra crossing is in a passable state, the second light strip 140 works; when the zebra crossing is in a no-passable state, the first light strip 130 works.
[0033] It should be noted that the traffic sign 100 of the technical solution of the present utility model can be a zebra crossing traffic sign 100, but is not limited to a zebra crossing sign.
[0034] It should also be noted that the working state of the second light strip 140 can be long-on, flashing, or breathing flashing; the working state of the first light strip 130 can be long-on, flashing, or breathing flashing; the specific working state can be set by technical personnel in this field according to actual needs.
[0035] The working state of the second light strip 140 and the working state of the first light strip 130 can change the pedestrians or drivers' active search for the traffic sign 100 into actively attracting the pedestrians and drivers to pay attention to the traffic sign 100, thereby improving the reminder function of the traffic sign 100 and ensuring traffic safety in a dim environment.
[0036] See also Figure 1 and Figure 2 On the basis of the above embodiment, the traffic sign 100 further includes a surface identification layer 150, and the surface identification layer 150 includes a semi-translucent key identification area 151 and a translucent area 152 surrounding the key identification area 151;
[0037] The key identification area 151 is located in the first illumination area; the second light strip 140 illuminates the key identification area 151 so that the key identification area 151 is illuminated. The light-transmitting area 152 is located in the second illumination area; the first light strip 130 illuminates the light-transmitting area 152 so that the light-transmitting area 152 is illuminated.
[0038] In a specific embodiment, the light transmittance of the light-transmitting area 152 is S1, and the light transmittance of the key identification area 151 is S2, wherein S1>S2. It is understandable that when the second light strip 140 is working, the second light strip 140 irradiates the inner periphery of the back plate layer 120 and forms a first illumination area. At this time, the first illumination area serves as the backlight source of the key identification area 151. In order to avoid the backlight source of the key identification area 151 being too bright, resulting in the inability to clearly observe the specific content of the traffic sign, the light transmittance of the key identification area 151 is set to be less than the light transmittance of the light-transmitting area 152.
[0039] Optionally, the light-transmitting area 152 is set to a white or yellow light-transmitting material, and the key identification area 151 is set to a semi-transmitting material, such as a semi-transmitting material with a blue background color as specified in the traffic sign design standard.
[0040] See also Figure 2In one embodiment, the surface identification layer 150 further includes an edge area 153 disposed on the periphery of the light-transmitting area 152, and the light transmittance of the edge area 153 is S3, wherein S3 <S2<S1。
[0041] Optionally, the edge area 153 is the opaque area 152 domain.
[0042] It should be noted that the configuration of the edge area 153 can highlight the overall shape of the traffic sign 100 .
[0043] See also Figure 1 In a preferred embodiment, the traffic sign 100 further includes a filter layer 160 , and the surface identification layer 150 is stacked on a side of the surface identification layer 150 away from the back plate layer 120 .
[0044] It is understandable that the filter layer 160 can soften the light. Optionally, the filter layer 160 is made of white light-transmitting material.
[0045] See also Figure 1 and Figure 3 In a specific embodiment of the present utility model, the back plate layer 120 includes a first protrusion 121 and a second protrusion 122 located outside the first protrusion 121, and the first protrusion 121 and the second protrusion 122 enclose the annular groove 120a;
[0046] The first light strip 130 is located inside the annular groove 120a, connected to the first protrusion 121, and irradiates in the direction of the second protrusion 122; the second light strip 140 is located inside the annular groove 120a, connected to the second protrusion 122, and irradiates in the direction of the first protrusion 121.
[0047] It should be noted that the first protrusion 121 and the second protrusion 122 are also made of light-transmitting materials. The light of the second light strip 140 passes through the first protrusion 121 and irradiates toward the inner periphery of the back plate layer 120. It can be understood that the first protrusion 121 can soften the light.
[0048] The light of the first light strip 130 is irradiated toward the periphery of the back plate layer 120 , so that the first light strip 130 only illuminates the light-transmitting area 152 , which is different from the display state of the second light strip 140 when it is working.
[0049] It should also be noted that the second light strip 140 is installed on the second protruding piece 122 and irradiates in the direction of the first protruding piece 121 , so that the second light strip 140 illuminates the light-transmitting area 152 and the key marking area 151 at the same time.
[0050] See also Figure 1 and Figure 3 In the above technical embodiment, the backplane layer 120 further includes a third protrusion 123 , and the third protrusion 123 is arranged around the front side of the backplane layer 120 and located at the edge of the backplane layer 120 .
[0051] It can be understood that the third protrusion 123 can reinforce the back plate layer 120, and the provision of the third protrusion 123 can play a light shielding role.
[0052] Optionally, the filter plate and / or the surface marking area is connected to the back plate layer 120 via the first protrusion 121 , the second protrusion 122 , and the third protrusion 123 .
[0053] Optionally, in a specific embodiment of the present utility model, the traffic sign 100 also includes a control system (not shown in the figure), which is used to receive external signals. The control system is connected to the first light strip 130 and the second light strip 140 by signal, and is used to control the first light strip 130 and the second light strip 140 to emit light.
[0054] It can be understood that the external signal that the control system can be used to receive may be a traffic light signal of road traffic, or a visual sensor signal.
[0055] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
