Embodiments of the present disclosure relate to a luminescent reticle that may be used to identify pedestrians or motor vehicle drivers on the pavement of a roadway. For example, a pedestrian or a driver of a motor vehicle is informed of the road condition of a road ahead by emitting light having predetermined information. The luminous marking according to the embodiment can help pedestrians or motor vehicle drivers to know road conditions in time and optimize road traffic.

The light-emitting reticle according to the present embodiment may be also referred to as a road reticle, a reticle, an electronic reticle, or the like. The names are used to indicate markings for marking on the road surface according to the present embodiment, and should not be construed as limiting.

Fig. 1 is a schematic view showing an application scenario of a luminescent reticle 1 according to an example of the present embodiment.

As shown in fig. 1, in some examples, a light-emitting marking 1 may be provided on a road 100 for identifying road conditions of the road 100 ahead. In some examples, the luminescent reticle 1 may emit light of different colors, such as one or more of white, yellow, and green. In some examples, different colors of light may be used to represent different road conditions. In some examples, the luminescent reticle 1 may emit light in different ways, such as flashing twice consecutively or flashing three times consecutively, etc. In some examples, different lighting patterns of the lighted sign 1 can be used to represent different road conditions. Under the condition, the road condition information can be transmitted to pedestrians and motor vehicle drivers in real time through the color and/or the luminous mode, so that the pedestrians and motor vehicle drivers can reasonably select roads based on the road condition information, and the purpose of optimizing road traffic is achieved.

In some examples, the luminescent reticle 1 may be disposed in a recess formed on the road 100. In some examples, the upper surface of the luminescent reticle 1 may be flush with the road surface of the road 100. In this case, the function of transmitting information can be performed without affecting traffic. In some examples, the upper surface of the luminescent marking line 1 may also be higher than the road surface of the road 100. In other examples, the upper surface of the luminescent marking line 1 may also be lower than the road surface of the road 100.

In some examples, the road 100 may be a public road such as an urban road or an expressway.

In some examples, the luminescent reticle 1 may be rectangular in some examples. The length of the illuminated reticle 1 may be between 1000 mm and 3000 mm. For example, the length of the luminescent reticle 1 may be 1000 mm, 1100 mm, 1200 mm, 1300 mm, 1400 mm, 1500 mm, 1600 mm, 1700 mm, 1800 mm, 1900 mm, 2000 mm, 2200 mm, 2400 mm, 2600 mm, 2800 mm, or 3000 mm. The width of the illuminated reticle 1 may be between 100 mm and 200 mm. For example, the width of the luminescent reticle 1 may be 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 170 mm, 180 mm, 190 mm, or 200 mm. The thickness of the luminescent reticle 1 may be between 20 mm and 40 mm. For example, the thickness of the luminescent reticle 1 may be 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, or 40 mm.

In some examples, since the speed of the vehicle on the highway is generally higher than the speed of the vehicle on the urban road, the size of the illuminated marking 1 on the highway may generally be larger than the size of the illuminated marking 1 on the urban road so that the illuminated marking 1 can be more easily found by the motor vehicle driver. In some examples, when the luminescent marking 1 is disposed on a city road, the luminescent marking 1 is preferably 2000 mm long, 150 mm wide, and 30 mm thick. In other examples, when the luminescent marking 1 is disposed on a highway, the luminescent marking 1 is preferably 3000 mm long, 150 mm wide and 30 mm thick.

Fig. 2A is a schematic diagram showing a luminescent reticle 1 according to an example of the present embodiment; fig. 2B is an exploded view showing the luminescent reticle 1 according to the present embodiment example; fig. 2C is a cross-sectional view showing the luminescent reticle 1 according to the present embodiment.

In some examples, the luminescent reticle 1 may be designed in different shapes. For example, the luminous reticle 1 may be designed as a rectangle, triangle or diamond. In the embodiment shown in fig. 2A, the luminescent reticle 1 is rectangular. In some examples, differently shaped illuminated markings 1 may be stitched into pavement markings such as straight arrows, curved arrows, and the like. In some examples, the shape of the luminescent reticle 1 may meet the shape required in the specification of road traffic signs and reticles. In other examples, the luminescent reticle 1 may be used with conventional traffic reticles.

In some examples, the luminescent reticle 1 may include a light transmissive layer 20, a light guiding layer 30, and a light source 40 (see fig. 2B). The light source 40 may be used to emit light that makes the luminescent marking 1 marking. The light guide layer 30 may allow light transmission from the light source 40 and may be used to increase the lifetime or luminous efficacy of the luminous reticle 1. The light-transmitting layer 20 may be used to transmit light emitted by the light source 40. The light-transmitting layer 20 can reflect the light of the external environment to improve the recognition of the luminous marking 1 on the road 100, so as to strengthen the marking effect of the publication marking 1.

In some examples, the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 may be directly connected by bonding, clamping (using clamping members), screwing, or the like.

In some examples, a side of the light transmissive layer 20 remote from the light guide layer 30 may be a slip resistant wear resistant side (described in detail below). In other words, when the light-emitting marking 1 is disposed on the road 100, the upwardly facing surface of the light-transmitting layer 20 may be an anti-slip wear-resistant surface. In some examples, the anti-skid wear-resistant surface is a rough surface with certain roughness, and can diffusely reflect the light of a vehicle headlight and has anti-skid capability meeting the vehicle traffic safety standards. In this case, the light-emitting reticle 1 can be provided with a certain surface roughness and a certain reflectance, and the discrimination of the light-emitting reticle 1 when irradiated with light can be improved; further, the upward surface of the light-transmitting layer 20 is provided as an anti-slip wear-resistant surface, so that the problem of glare due to too strong light emitted from the headlight of the vehicle can be reduced as much as possible. In other examples, the anti-slip wear surface may be a diffuse reflective surface having a degree of reflectivity. In some examples, the degree of reflectance may refer to the degree to which an object reflects light in different directions, the higher the degree of reflectance of an object, the easier it is to observe light reflected by an object from different angles when the light impinges on the object.

In some examples, the light guiding layer 30 is configured to buffer the pressure transmitted by the light transmitting layer 20 and support and protect the light source 40, or to enable the light emitted by the light source 40 to spread out of the road surface along a preset light path, or to enhance the light emitted by the light source 40 to the light transmitting layer, or to enable the light guiding layer 30 to have at least two of three functions (described in detail later).

In the present disclosure, the light source 40 is capable of emitting light representing road information to thereby transmit the road information to pedestrians or drivers of vehicles on the road, and in addition, the light source 40 is capable of emitting light transmitted through the road surface, thereby enabling the luminous marking 1 to also play a role of identification in the case of dim light; in addition, the light-transmitting layer 20 positioned at the outermost layer of the luminous marking 1 is provided with an anti-skid and wear-resistant surface, and the anti-skid and wear-resistant surface is formed by matching the adhesive material and the reflective material, so that the reflectivity and the anti-skid performance of the luminous marking 1 can be improved, and the identification degree of the luminous marking when being irradiated by lamplight can be improved; in addition, the light guide layer 30 has one of buffering protection, changing the light path of light, and enhancing the performance of light source light, so that the service life or the light emitting effect of the light emitting reticle 1 on a road can be improved.

The light-transmitting layer 20, the light-guiding layer 30, and the light source 40 may be disposed in a groove of a road surface after being laminated. The light-transmitting layer 20, the light-guiding layer 30 and the light source 40 may not be connected, and the light-transmitting layer 20, the light-guiding layer 30 and the light source 40 may be fixedly connected by bonding, screwing, clamping by a clamping member, or the like.

In some examples, a buffer sheet may be disposed between any two of the light transmissive layer 20, the light guide layer 30, and the light source 40. Thus, the impact resistance among the three is enhanced.

In some examples, a waterproof glue, transparent glue, etc. may also be used to completely encapsulate the light transmissive layer 20, the light guiding layer 30, and the light source 40. Therefore, the three parts are connected and fixed, and the protection performance of the three parts can be enhanced.

In some examples, the luminescent reticle 1 may further comprise a housing 10. The housing 10 may be used to carry the light transmissive layer 20, the light guiding layer 30, and the light source 40 disposed in the housing 10.

In some examples, the housing 10 may be rectangular. The housing 10 may have a mounting chamber 11 and an opening 12 (see fig. 2B and 2C). The opening 12 may communicate with the mounting chamber 11. The mounting chamber 11 may be used to house the light transmissive layer 20, the light guiding layer 30, and the light source 40. In some examples, light emitted by the light source 40 may propagate out of the mounting chamber 11 through the light guiding layer 30, the light transmitting layer 20, and the opening 12 in this order. In some examples, the opening 12 may be oriented toward the road surface when the light emitting reticle 1 is embedded in the road surface of the road 100. In this case, the light transmitted from the opening 12 can be easily observed.

In some examples, the housing 10 may be made of a metallic material. Such as stainless steel, aluminum, titanium, aluminum alloys, titanium alloys, cast iron, magnesium alloys, or copper alloys, among others.

Additionally, in some examples, the housing 10 may preferably be made of aluminum, titanium, or the like. In this case, the design and installation of the housing 10 can be facilitated by using the lightweight advantage of aluminum and titanium, and the manufacturing cost of the housing 10 can be reduced by using the inexpensive advantage of aluminum.

Additionally, in some examples, the material of the housing 10 is preferably stainless steel. In this case, the light-transmitting layer 20, the buffer member 31, and the light source 40 in the mounting chamber 11 can be supported by providing the housing 10 with good strength by selecting a metal material having good heat conduction properties, and heat generated when the light source 40 emits light can be radiated.

In some examples, the thickness of the housing 10 may be 1 millimeter to 5 millimeters. For example, the thickness may be 1 millimeter, 1.5 millimeters, 2 millimeters, 2.5 millimeters, 3 millimeters, 3.5 millimeters, 4 millimeters, 4.5 millimeters, or 5 millimeters. In some examples, the thickness of the housing 10 is preferably 2 millimeters.

Hereinafter, for convenience of description, a direction in which the opening 12 is directed to the bottom of the installation chamber 11 is understood as a D1 direction. In some examples, the D1 direction may be a vertically downward direction when the light emitting reticle 1 is disposed on the road 100.

In some examples, the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 may be sequentially arranged in the mounting chamber 11 in the D1 direction (see fig. 2B). In some examples, the light-transmitting layer 20 may be the outermost layer when the luminescent marking 1 is disposed on the road 100. In other words, the light-transmitting layer 20 contacts the vehicle or the pedestrian when the vehicle or the pedestrian passes. In some examples, light emitted by the light source 40 may propagate out through the light guide layer 30, the light transmissive layer 20, and the opening 12 in that order.

In some examples, the light source 40 may be an LED lamp. In some examples, the light source 40 may be a single LED lamp. In some examples, the light source 40 may be comprised of a plurality of LED lamps. Under the condition, the LED lamp has the characteristics of long service life, low working voltage, low power consumption and convenience in control, and the application range of the luminous marking line 1 can be improved. In some examples, each of the plurality of LED lamps can cooperate to convey different information by changing the manner in which the light is emitted, thereby enabling the light-emitting reticle 1 to convey different information. In other examples, light source 40 may be any device that emits light.

In some examples, the light source 40 may be a single-color or multi-color LED lamp. In some examples, when the light source 40 is a single color LED lamp, the LED lamp may be a white LED lamp. The color of the light emitted by the white LED lamp can be the color of the light reflected by a traditional pavement marking. Therefore, the white LED lamp can emit warning light rays which are the same as the white light rays reflected by the normal pavement marking.

In some examples, when the light source 40 is a multicolor LED lamp, the LED lamp may be a white, red, yellow, or green LED lamp. The color of the light emitted by the red, yellow or green LED lamp may be the color of the light emitted by a traffic light. Thus, the red, yellow or green LED lamp can emit warning light with the same color as the light emitted by the traffic light.

In some examples, the light source 40 may emit light vertically upward when the light emitting reticle 1 is disposed in the road 100. When the light emitting reticle 1 is disposed in the road 100, the opening portion 12 of the housing 10 may be disposed upward. In this case, the light emitted from the light source 40 can be sufficiently emitted out of the mounting chamber 11, so that the light-emitting reticle 1 is brighter with the same light source 40, thereby improving the recognition of the light-emitting reticle 1 on the road 100.

In some examples, a second gap f (see fig. 2C) may be formed between the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 and the side wall of the mounting chamber 11. In some examples, the second gap f may be filled with a waterproof glue. In other words, the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 are fixed in the installation cavity 11 by waterproof glue. In this case, the luminous reticle 1 can be provided with a certain waterproof performance by the waterproof adhesive, and the light source 40 is prevented from being damaged by water inflow during operation as much as possible.

In some examples, the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 may have a first gap e therebetween (see fig. 2C). The second gap f between the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 and the sidewall of the installation cavity 11 may be in communication with the first gap e between the light-transmitting layer 20, the light-guiding layer 30, and the light source 40. In this case, when the light-transmitting layer 20, the light-guiding layer 30, and the light source 40 are fixed in the mounting chamber 11, the waterproof glue can be poured into the second gap f directly, and the waterproof glue poured from the second gap f can flow to the first gap e, thereby facilitating the fixation of the light-transmitting layer 20, the light-guiding layer 30, and the light source 40.

In some examples, the waterproof glue may be a light transmissive material. In some examples, the light transmittance of the waterproofing adhesive may be not less than 50%. For example, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85% or 90%. This can increase the light emission luminance of the light-emitting reticle 1 as much as possible.

Fig. 3A is a schematic diagram showing the light-transmitting layer 20 according to the example of the present embodiment; fig. 3B is a sectional view showing the light-transmitting layer 20 according to the example of the present embodiment; fig. 3C is a cross-sectional view showing a modification of the light-transmitting layer 20 according to the present embodiment example.

In some examples, the light transmissive layer 20 may be planar. The light-transmitting layer 20 may include an adhesive material 21 and a light-reflecting material 22 (see fig. 3A). The retroreflective material 22 may be used to provide optical properties to the light transmissive layer 20 (e.g., to provide the light transmissive layer 20 with the ability to reflect light). The adhesive material 21 may be used to fix the reflective material 22. In some examples, the light transmissive layer 20 may be mixed from an adhesive material 21 and a light reflective material 22.

In some examples, the retroreflective material 22 may be granular. The reflective material 22 may reflect light. A number of retroreflective material 22 may be distributed in the adhesive material 21. In some examples, the reflective material 22 may be uniformly distributed inside the adhesive material 21. In other examples, the retroreflective material 22 may be embedded in the surface of the adhesive material 21. In other words, a part of the number of light reflecting materials 22 is located in the adhesive material 21, and another part is located outside the adhesive material 21. In other examples, the partially reflective material 22 may be uniformly distributed inside the adhesive material 21, and the partially reflective material 22 may be embedded on the surface of the adhesive material 21. Preferably, a portion of the light reflecting material 22 is located in the adhesive material 21 and another portion is located outside the adhesive material 21. In this case, the light reflecting material 22 can diffusely reflect light, so that the light reflecting degree of the luminous marking 1 can be improved, and the recognition degree of the luminous marking 1 when being irradiated by lamplight can be improved; in addition, the part of the reflective material 22, which is not embedded with the adhesive material 21, can improve the surface roughness of the light-transmitting layer 20, thereby improving the anti-slip property of the light-transmitting layer 20 and further improving the safety of the vehicle when driving through the luminous marking line 1.

In some examples, the adhesive material 21 may at least partially encapsulate the retroreflective material 22. In this case, the anti-slip wear-resistant surface can be formed by a plurality of reflective materials 22 which can reflect light and are distributed in the adhesive material 21 to diffusely reflect light irradiated on the reflective materials 22, so that the light-transmitting layer 20 can diffusely reflect light, and at the same time, the light-emitting marking 1 can be provided with a certain roughness or anti-slip capability.

In some examples, the adhesive material 21 may partially encapsulate the retroreflective material 22 (see fig. 3B). In other words, the reflective material 22 may be partially embedded in the adhesive material 21, i.e. distributed on the surface of the adhesive material 21. In some examples, the portion of the reflective material 22 not embedded in the adhesive material 21 may cooperate with the surface of the adhesive material 21 to form a slip resistant wear resistant surface. In this case, when light is irradiated to the anti-slip wear-resistant surface of the light-transmitting layer 20, the light can be diffusely reflected with the cooperation of the number of light-reflecting materials 22; in addition, the part of the reflective material 22, which is not embedded with the adhesive material 21, can improve the surface roughness of the light-transmitting layer 20, thereby improving the anti-slip property of the light-transmitting layer 20 and further improving the safety of the vehicle when driving through the luminous marking line 1.

In some examples, the adhesive material 21 may completely encapsulate a number of the retroreflective material 22 (see fig. 3C). In other words, a number of retroreflective materials 22 may be distributed inside the adhesive material 21. In this case, when light is irradiated to the inside of the reflective material 22, the light can be diffusely reflected with a plurality of the reflective materials 22 being matched; in addition, the reflective material 22 is distributed inside the adhesive material 21, so that the reflective material 22 is prevented from being worn during use as much as possible, and the wear resistance of the light-transmitting layer 20 is improved.

In some examples, the light reflective material may be made of a light reflective material such as polyurethane, polycarbonate, or the like.

In some examples, the retroreflective material 22 may be glass particles, plastic particles, rubber particles, or the like. In some examples, the retroreflective material 22 is preferably glass or plastic microbeads.

In some examples, the retroreflective material 22 may be spherical. In this case, the spherical reflective material 22 may reflect light from various angles, thereby enhancing the diffuse reflection ability of the light-transmitting layer 20.

In some examples, the adhesive material 21 may be one or more of epoxy, polyurethane, polyethylene, polyvinyl chloride, polypropylene, polyurea, acrylate, and plastic extender oil.

In some examples, the adhesive material 21 may be gelatinous when mixed with the retroreflective material 22 and may be cured after the mixed manufacture with the retroreflective material 22 is completed. In this case, it can be convenient to mix the adhesive material 21 with the light reflecting material 22 and can be cured after mixing to form a structure having a desired morphology.

In some examples, the adhesive material 21 may be a thermosetting material. In some examples, when the adhesive material 21 is a thermosetting material, the softening temperature of the cured adhesive material 21 is not less than 80 ℃. For example, the softening temperature of the cured adhesive material 21 may be 80 ℃, 90 ℃, 100 ℃, 110 ℃, 120 ℃, 130 ℃, 140 ℃, or 150 ℃. In this case, the light-transmitting layer 20 can be made to have good thermal stability when used on the road 100. In other examples, the adhesive material 21 may also be a thermoplastic material.

In some examples, the retroreflective material 22 may be 20 mesh to 250 mesh in size. For example, the retroreflective material 22 can be 20 mesh, 30 mesh, 40 mesh, 50 mesh, 60 mesh, 70 mesh, 80 mesh, 90 mesh, 100 mesh, 120 mesh, 140 mesh, 160 mesh, 180 mesh, 200 mesh, 220 mesh, 240 mesh, or 250 mesh in size. In this case, the reflective material 22 can be mixed with the adhesive material 21 in a proper size, so that the diffuse reflection capability of the light-transmitting layer 20 is improved as much as possible, and the adhesive material 21 is convenient to fix the reflective material 22, thereby improving the overall stability.

In some examples, the mass of the adhesive material 21 of the light transmissive layer 20 does not exceed 20% of the mass of the light reflective material 22. For example, the mass of the adhesive material 21 may be 20%, 18%, 16%, 14%, 12%, 10%, 8%, 6%, 4%, or 2% of the mass of the retroreflective material 22. In this case, it is possible to facilitate the bonding of the adhesive material 21 and the light reflecting material 22, and to improve the stability of the entire light transmitting layer 20.

In some examples, the light transmittance of the light transmitting layer 20 formed of the adhesive material 21 and the light reflecting material 22 is not less than 50%. For example, 50%, 60%, 70%, 80%, or 90%. In this case, the light emitted from the light source 40 can be transmitted through the light-transmitting layer 20 better, so that the luminous reticle 1 can perform a better marking function.

The present disclosure also provides a method for preparing the light-transmitting layer 20, and fig. 4 is a flowchart illustrating the preparation of the light-transmitting layer 20 according to an example of the present embodiment.

In this embodiment, the method for preparing the light-transmitting layer 20 may include: paving a layer of adhesive material 21 (step S100); uniformly embedding the reflective material 22 into the adhesive material 21 before curing the adhesive material 21 (step S200); the adhesive material 21 and the light reflecting material 22 are left standing for a preset time to cure the adhesive material 21 (step S300).

In some examples, in step S100, the thickness of the laid adhesive material 21 may be at least one half the diameter of the retroreflective material 22. In some examples, the thickness of the adhesive material 21 may be 0.03 millimeters, 0.05 millimeters, 0.07 millimeters, 0.09 millimeters, 0.1 millimeters, 0.15 millimeters, 0.2 millimeters, 0.25 millimeters, 0.3 millimeters, 0.35 millimeters, or 0.4 millimeters. In this case, the adhesive material 21 can be made to have a sufficient thickness to cover the light reflecting material 22.

In some examples, in step S200, one-half of the volume of the retroreflective material 22 may be embedded in the adhesive material 21. In this case, the portion of the reflective material 22 where the adhesive material 21 is not embedded may form a plurality of protrusions on the surface of the adhesive material 21, so that the friction coefficient of the light-transmitting layer 20 can be increased, and the anti-slip property of the light-transmitting layer 20 can be improved.

In some examples, in step S300, the adhesive material 21 and the light reflecting material 22 may be left standing at normal temperature for a preset time to cure the adhesive material 21. The preset time may be, for example, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, … …, 23 hours, 24 hours, or the like.

In some examples, after step S300, step S100 and step S200 may be repeated. In other words, after the first layer of adhesive material 21 is cured, a layer of adhesive material 21 is laid on the reflective material 22 fixed on the first layer of adhesive material 21, and the reflective material 22 is embedded into the newly laid layer of adhesive material 21 before the newly laid layer of adhesive material 21 is cured. In this case, the light-transmitting layer 20 can be made to contain more light-reflecting material 22, thereby improving the reflectance of the light-transmitting layer 20; in addition, the light-transmitting layer 20 has a larger thickness, and the light-reflecting material 22 inside the adhesive material 21 is not easy to wear, so that the service life of the light-transmitting layer 20 can be prolonged.

In some examples, steps S100 and S200 may be repeated multiple times. In other words, the light-transmitting layer 20 may be composed of a plurality of layers of adhesive material 21 and a plurality of layers of light-reflecting material 22 laid.

In other examples, the light-transmitting layer 20 may also be obtained by directly mixing and stirring the adhesive material 21 and the light-reflecting material 22.

By using the method of steps S100 to S300, a light-transmitting layer 20 is prepared, in which the ratio of the adhesive material 21 to the light-reflecting material 22 is 1:5, wherein the light-reflecting material 22 is glass beads, the adhesive material 21 is epoxy resin, and the performance of the light-transmitting layer 20 obtained by the preparation method is tested, and the results are shown in table 1. In some examples, the ratio 1:5 may be a mass ratio; in other examples, the ratio 1:5 may also be a volume ratio.

Fig. 5A is a schematic diagram showing a light guide layer 30 according to an example of the present embodiment; fig. 5B is an exploded view showing the light guide layer 30 according to the example of the present embodiment.

Referring to fig. 5A and 5B, in some examples, the light guide layer 30 may include a buffer member 31.

In some examples, the buffer member 31 may be configured to buffer pressure transmitted by the light-transmitting layer 20 and support and shield the light source 40. The buffer member 31 can provide the luminescent reticle 1 with compression resistance and impact resistance. In other words, the buffer member 31 may be configured to buffer the pressure transmitted from the light-transmitting layer 20 and support and protect the light source 40.

In some examples, the cushioning members 31 may include a first cushioning member 311, a second cushioning member 312, and a third cushioning member 313 (see fig. 5B). The first, second, and third buffer members 311, 312, and 313 may be in a flat plate shape. In some examples, the first buffer member 311, the second buffer member 312, and the third buffer member 313 may be sequentially stacked. In other words, the second cushioning member 312 is sandwiched by the first cushioning member 311 and the third cushioning member 313. In some examples, when the buffer member 311 is disposed in the light emitting reticle 1, the first buffer member 311, the second buffer member 312, and the third buffer member 313 may be sequentially stacked along the D1 direction.

In some examples, the first, second, and third buffer members 311, 312, and 313 may be made of a light-transmitting material. In other words, the buffer member 31 may be made of a light-transmitting material. In some examples, the transmittance of the buffer member 31 is not less than 50%. For example, the transmittance of the buffer member 31 may be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, or 90%. This can increase the light emission luminance of the light-emitting reticle 1 as much as possible.

In some examples, the first and third cushioning members 311, 313 may be made of an impact-resistant material. In some examples, the first cushioning member 311 and the third cushioning member 313 may have impact resistance. In some examples, the second cushioning member 312 may be made of a compression resistant material. In some examples, the second cushioning member 312 may have compressive properties. In this case, the first buffer member 311 and the third buffer member 313 made of the impact-resistant material can provide the buffer member 31 with a certain impact resistance at the outermost layer of the buffer member 31, so that the buffer member 31 can provide the luminous reticle 1 with a certain impact resistance, thereby enabling the luminous reticle 1 to withstand the impact force when the vehicle passes; in addition, the second buffer member 312 made of a compression-resistant material between the first buffer member 311 and the third buffer member 313 can provide a certain compression resistance to the buffer member 31, so that the buffer member 31 can have a certain compression resistance to the light-emitting reticle 1, thereby enabling the light-emitting reticle 1 to withstand the pressure of the vehicle on the light-emitting reticle 1 when the vehicle is stopped on the light-emitting reticle 1; further, disposing the second cushioning member 312 made of a compression-resistant material between the first cushioning member 311 and the third cushioning member 313 made of an impact-resistant material can provide impact-resistant protection to the second cushioning member 312 by the first cushioning member 311 and the third cushioning member 313, avoiding as much as possible the second cushioning member 312 from being damaged when impacted.

In some examples, the impact resistant material may be polycarbonate, polymethyl methacrylate, or polyoxymethylene. In some examples, the impact resistant material is preferably polycarbonate. In some examples, the compressive material may be tempered glass. In some examples, the materials of the first, second, and third buffer members 311, 312, and 313 are preferably polycarbonate, tempered glass, and polycarbonate, in order. In this case, the cushioning member 31 can have impact resistance and compression resistance; in addition, the toughened glass is arranged between the two layers of polycarbonate, and the toughened glass can be protected through the polycarbonate, so that the toughened glass is prevented from being broken when in use as much as possible.

In other examples, the second cushioning member 312 may also include multiple layers of laminated impact and compression resistant materials. For example, the second buffer member 312 may include laminated polycarbonate and tempered glass; the second buffer member 312 may also include polycarbonate, tempered glass, and polycarbonate, which are sequentially stacked. In this case, the second cushioning member 312 can be made to have both impact resistance and compression resistance by providing the second cushioning member 312 in a multilayer structure, thereby improving the compression resistance and impact resistance of the cushioning member 31.

In some examples, the first, second, and third buffer members 311, 312, and 313 may be bonded by a thermal compression process. In this case, the first, second, and third buffer members 311, 312, and 313 can be more firmly connected, so that the buffer member 31 has stable impact resistance and compression resistance.

In other examples, the first, second, and third buffer members 311, 312, and 313 may also be integrally formed. In this case, the stability of the cushioning member 31 can be improved.

In some examples, the first, second, and third buffer members 311, 312, and 313 may be fixedly connected inside the housing 10. The connection method may be, for example, a fastening method such as a clamping method, an adhesive method, or a screw method.

In some examples, the thickness of the first cushioning member 311, the second cushioning member 312, and the third cushioning member 313 is at least 2 millimeters to 6 millimeters. For example, the thickness may be 2 millimeters, 2.5 millimeters, 3 millimeters, 3.5 millimeters, 4 millimeters, 4.5 millimeters, 5 millimeters, 5.5 millimeters, or 6 millimeters.

In some examples, cushioning member 31 may also include at least one shock absorbing tab (shown). This can further enhance the impact resistance of the luminescent marking 1, and reduce damage to the luminescent marking 1 caused by rolling of the vehicle.

In some examples, shock absorbing sheets may be disposed between the first, second, and third cushioning members 311, 312, 313.

In other examples, a shock absorbing sheet may be disposed between the first buffer member 311 and the light-transmitting layer 20, and a shock absorbing sheet may also be disposed between the third buffer member 313 and the light source 40.

It will be appreciated that the cushioning component may also be disposed between any other component or member to cushion the pressure transmitted by the vehicle to the housing 10 or components within the housing 10. Preferably, a cushioning member may be disposed between the more rigid components to cushion the pressure between the components.

In some examples, the size of the shock absorbing sheet may be smaller relative to the size designs of the first, second, and third buffer members 311, 312, and 313, thereby enabling a reduction in blocking of light.

Fig. 6 is a cross-sectional view showing a cushioning member 31 according to an example of the present embodiment.

Referring to fig. 6, in some examples, the buffer member 31 may further include a light refracting part 315, and the light refracting part 315 may be configured to transmit light emitted from the light source 40 out of the road surface along a preset light path. In other words, the light refracting part 315 may be used to deflect light incident on the buffer member 31 by a predetermined angle and then emit the deflected light. In this case, even for a unidirectional road surface such as a highway, the light refracting part 315 deflects the light emitting line in the direction in which the vehicle travels, and the light is deflected in one direction, so that the loss of light can be reduced and the light intensity can be improved.

In the present embodiment, the light emitted from the light source 40 is deflected by a predetermined angle through the light refracting part 315 and then exits the mounting chamber 11. In this case, the light emitted from the light source 40 can be deflected by the light refracting part 315, so that the light emitted from the light source 40 can be deflected toward the human eye, and thus it is possible to facilitate the driver or pedestrian of the motor vehicle on the road 100 to find the light emitting reticle 1 within a predetermined distance through the light emitted from the light emitting reticle 1, thereby improving the recognition of the light emitting reticle 1 on the road 100.

In some examples, the light source 40 may emit light vertically upward when the light emitting reticle 1 is disposed in the road 100. The light refracting part 315 may deflect light emitted vertically upward from the light source 40 by 20 ° to 70 °. In some examples, the deflected light rays are at an angle of 20 ° to 70 ° to the surface of the road 100. For example, the included angle may be 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 65 °, or 70 °.

In some examples, the light refracting part 315 may be disposed on the first buffer member 31, the second buffer member 32, or the third buffer member 33. In the embodiment shown in fig. 6, the light refracting part 315 is provided at the first buffer member 31.

In some examples, the first cushioning member 311 may have a notch 314. The notch 314 may be quadrilateral. The notch 314 may be located on a side of the first cushioning member 311 adjacent to the second cushioning member 312. The plane on which the top of the notch 314 is located (i.e., plane L shown in fig. 6) and the plane of the second cushioning member 312 facing the first cushioning member 311 are not parallel to each other. In this case, when light is irradiated from the bottom vertically upward to the plane L, the light is refracted rightward in the light refracting part 315 until being emitted from the first buffer member 311, whereby the light emitted from the first buffer member 311 can be obliquely irradiated to the human eye, and the warning effect of the light-emitting reticle 1 on a distant pedestrian or driver can be enhanced. The oblique direction of the light rays can be adaptively adjusted according to the oblique angle of the plane L.

In some examples, the portion above plane L may be referred to as light refracting part 315. In some examples, the light refracting part 315 may correspond to a prism provided on the first buffer member 311. The prism may be a transparent object surrounded by planes intersecting each other but not parallel to each other. When light passes through the prism, the path of the light is deflected. In this case, the light can be deflected when passing through the light refracting part 315, so that the light emitted from the light-emitting reticle 1 is more easily directed toward the human eye, thereby improving the recognition of the light-emitting reticle 1 on the road 100.

In other examples, the light refracting part 315 may also be disposed on the second buffer member 312 or the third buffer member 313. The light refracting part 315 is disposed on the second buffer member 312 or the third buffer member 313 in a manner similar to that of the first buffer member 31, and will not be described again.

In other examples, light refracting part 315 may be a polygonal prism. The light refracting part 315 may be disposed on the first buffer member 311, the second buffer member 312, or the third buffer member 313. In some examples, light refracting portion 315 may be a triangular prism, a four-prism, a five-prism, or a six-prism. The light ray may be deflected after passing through the light refracting part 315. In some examples, a particular prism may be selected for the angle of the light deflection as desired.

In summary, according to the present disclosure, it is possible to provide a luminous marking 1 that transmits road information according to road conditions and can perform a marking function on the road surface of a road 100 in the case of dim light; furthermore, it is provided that; the anti-slip wear-resistant surface of the light-transmitting layer 20 of the light-emitting marking 1 can diffusely reflect light irradiated on the light-transmitting layer 20, so that in the case, the light reflection degree of the light-emitting marking 1 can be improved, the identification degree of the light-emitting marking 1 when being irradiated by lamplight is improved, the surface roughness of the light-transmitting layer 20 can be improved by the part of the light-reflecting material 22, which is not embedded with the adhesive material 21, and the anti-slip property of the light-transmitting layer 20 is improved; in addition, the surface of the light-transmitting layer 20 close to the road surface of the road 100 is set as an anti-skid and wear-resistant surface, and the anti-skid and wear-resistant surface is a rough surface with certain roughness, and can diffuse reflection of the light rays of the headlight of the vehicle, so that the dazzling problem caused by the too strong light rays irradiated by the headlight of the vehicle can be avoided as much as possible, and the luminous marking 1 can have anti-skid capability; further, the buffer member 31 can provide the luminous reticle 1 with a certain compression resistance and impact resistance, and thus can improve the life of the luminous reticle 1 in use.

Fig. 7 is an exploded view showing another example of the luminescent reticle 1 according to the present embodiment example.

Referring to fig. 7, in some examples, light guiding layer 30 may also include a lens assembly 32. The lens assembly 32 may be configured to enhance the light emitted from the light source 40 to the light transmissive layer. In this case, the dispersion of light can be reduced by the lens assembly 32, and the brightness of light emitted from the light source 40 can be enhanced.

In some examples, the lens assembly 32 may include a plurality of lenses arranged in an array, and the lens assembly 32 may be disposed between the buffer member 31 and the light source 40. In other words, the lens assembly 32 may be disposed proximate to the light source 40. In this case, the brightness of the light emitted from the light source 40 can be made more uniform by the plurality of lenses arranged in an array.

In some examples, the lens assembly 32 may also be disposed between the buffer member 31 and the light transmissive layer 20. This enhances or focuses the light transmitted through the buffer member 31, and then uniformly emits the light to the light-transmitting layer 20.

Referring to fig. 7, in some examples, the light source 40 may include a circuit board 42 and a plurality of LED lamps 41 disposed on the circuit board 42.

In some examples, a plurality of LED lamps 41 may be arranged in an array on a circuit board 42.

In some examples, the plurality of lenses arranged in an array and the plurality of LED lamps 41 arranged in an array may be in one-to-one correspondence. That is, each lens may be disposed above each LED lamp 41, respectively, to ensure that light emitted from each LED lamp 41 can pass through the lens disposed in front thereof. In this case, it can be ensured that each lens converges and enhances the light emitted from the single LED lamp 41, and the plurality of lenses arranged in an array can ensure that the light emitted from the plurality of LED lamps 41 can be emitted uniformly.

In some examples, the inner wall of the housing 10 may be provided with a light reflecting layer 50 that reflects light of the light source 40 to the opening 12. The light reflecting layer 50 may be disposed on at least one inner wall of the housing 10 to the upper. Of course, a reflective layer may be provided on each inner wall of the housing. Therefore, the absorption of the inner wall of the shell to the light can be reduced, and the light emission rate can be increased.

In some examples, the light reflecting layer 50 may be a plate-shaped mirror structure for reflecting light of the light source 40. In some examples, the retroreflective layer 50 may be retroreflective material applied to the interior walls of the housing 10. In some examples, the thickness of the retroreflective layer 40 may be less than 1 millimeter. In some examples, the light reflecting layer 40 may be a light reflecting film, which may be one of tin foil, white plastic paper, and pineapple. Preferably, the light reflecting layer 40 may be a tinfoil.

Referring to fig. 7, in some examples, the luminescent reticle 1 may further include a heat sink 60. The heat sink 60 may be configured to radiate heat generated from the light source 40 to the outside of the luminous reticle 1. Accordingly, the heat generated by the light source 40 can be dissipated to the outside of the luminescent reticle 1 by the heat sink 60, and the heat accumulation in the luminescent reticle 1 can be reduced.

In some examples, the heat sink 60 may include stacked laminations and a cannula through which the laminations are threaded. In some examples, the laminate may be used for heat dissipation and the cannula may be used for heat conduction. In this case, the heat generated from the light source 40 can be sufficiently dissipated to the outside of the luminous reticle 1 by using the combined structure of the lamination and the cannula.

In some examples, the laminations may be equidistantly disposed. In some examples, the stacking direction of the laminations may be D1 as shown in fig. 2B, at which time the cannula may extend through the laminations in a direction opposite D1 to the opening 12 of the housing 10. Thereby, it is possible to easily conduct heat generated by the light source 40 to the outside of the casing 10.

In some examples, the stacking direction of the lamination may be a direction toward the side wall of the housing 10 as shown in fig. 7, and the insertion tube may be inserted through the lamination in the stacking direction of the lamination and then extend to the opening 12 of the housing 10 in the opposite direction of D1. Thereby, it is possible to easily conduct heat generated by the light source 40 to the outside of the casing 10.

In other words, one end of the heat sink 60 may be in proximity to or in contact with the light source 40, and the other end of the heat sink 60 may leak out of or be in contact with the housing. Under the condition, the heat emitted by the heat dissipation piece can be used for melting ice cubes or ice and snow, so that the travel of people is facilitated.

In some examples, pre-holes may be pre-formed in the laminate, and the laminate may be connected through the pre-holes. In some examples, the diameter of the cannula may be greater than the diameter of the preformed hole, thereby enabling an interference fit of the cannula and the lamination.

In some examples, the spacer may be a heat sink of any material, such as copper or aluminum. In some examples, the cannula may be a heat pipe of any material, such as copper, aluminum, iron, tungsten, and alloys thereof.

In some examples, the heat pipe may preferably be a hollow pipe. Therefore, compared with a solid pipe, the heat conduction and radiation performance can be enhanced.

Referring again to fig. 7, in some examples, the luminescent reticle 1 may further comprise a stiffener 9 disposed at least partially around the light transmissive layer. In some examples, the stiffener 9 may be disposed on top of the housing 10 and configured to enhance the protective properties of the illuminated reticle. Thereby, the protective performance or the wear resistance of the luminous marking can be enhanced by the reinforcement member provided around the light-transmitting layer.

In some examples, the stiffener 9 may be additionally added to the top of the housing 10. The reinforcement 9 may be flush with the road surface or slightly protrude from the road surface. Thus, the portion protruding from the road surface can increase the wear resistance of the luminescent marking. In addition, the additional reinforcement 9 can also facilitate the installation of the components within the housing 10.

In some examples, the stiffener 9 may be integrally designed with the housing 10. The reinforcement 9 may be of the same material as the housing 10. In some examples, the stiffener 9 may be made of a metallic material. Such as stainless steel, aluminum, titanium, aluminum alloys, titanium alloys, cast iron, magnesium alloys, or copper alloys, among others.

In some examples, the stiffener 9 and the shell 10 may be an aluminum casting, a titanium casting, an aluminum alloy casting, a titanium alloy casting, or the like.

Fig. 8 is a structural diagram showing one example of the reinforcing member 9 according to the present embodiment example.

Referring to fig. 8, in some examples, the stiffener 9 may include a grid bracket 91. In this case, the mesh holder 91 can be used to enhance the impact resistance of the luminescent reticle 1, and can also be used to further protect the components within the housing 10.

In some examples, mesh holes 92 may be formed in the mesh support 91. In some examples, the light transmissive layer 20 formed of the adhesive material 21 and the light reflective material 22 may be exposed to the road surface through the mesh holes 92. This allows light to pass through the mesh voids 92, ensures that the light-transmitting layer 20 is exposed to the road surface, and further exhibits the anti-skid and wear-resistant properties of the light-transmitting layer.

In some examples, a plurality of protrusions 93 may be provided on the grid support 91. In this case, the vehicle can be further made slip-resistant by using the plurality of projections 93 on the mesh bracket 91.

In some examples, the plurality of protrusions 93 may be arranged on the grid support 91 in a uniform or non-uniform manner. In some examples, the plurality of protrusions 93 may be hemispherical, polygonal, or other irregular shapes, etc.

In some examples, the plurality of protrusions 93 may be the same material as the mesh support 91. That is, the plurality of projections 93 may be made of a metal material. Such as stainless steel, aluminum, titanium, aluminum alloys, titanium alloys, cast iron, magnesium alloys, or copper alloys, among others. Therefore, the plurality of protrusions 93 made of metal can not only improve the anti-skid performance of the luminous marking 1, but also improve the wear resistance of the luminous marking 1.

In some examples, the plurality of protrusions 93 may be formed on the grid support 91 using spot welding.

Referring to fig. 9, further embodiments of the present disclosure are also directed to a smart road marking system that may include a plurality of traffic markings 100 comprised of illuminated markings as described above.

In some examples, the smart light reticle system may further include a light sensor 600, a power supply 200, and a control 300.

In some examples, the light sensor 600 may be configured to sense the light intensity of the environment in which the traffic marking 100 is located.

In some examples, the power supply 200 may be configured to supply power to the traffic marking 100.

In some examples, the control device 300 may be configured to control the power supply output from the power supply device 200 to the traffic marking 100 according to the light intensity sensed by the light sensor 600, thereby controlling the luminous intensity of the traffic marking 100.

In some examples, referring again to fig. 9, an output of the light sensor 600 may be connected to the control device 300, an output of the control device 300 may be connected to the power supply device 200, and an output of the power supply device 200 may be connected to the traffic marking 100.

In the intelligent road marking system according to the present disclosure, the light sensor 600 can monitor the brightness of the environment where the traffic marking 100 is located in real time, and the control device 200 can regulate and control the luminous intensity of the traffic marking 100 according to the brightness monitored by the light sensor 600, so that the traffic marking 100 can switch different luminous brightnesses in different environments, the electric quantity consumption of the luminous marking 1 can be reduced, and the service life of the luminous marking 1 can be prolonged.

In some examples, the light sensors 600 may be equally distributed along the traffic segment. For example, the light sensors 600 are uniformly arranged every 50 meters, 100 meters, 150 meters, 200 meters, or the like on the traffic section. Therefore, the ambient light brightness of each road section can be fully detected, and the reflection intensity of the traffic marking in the road section can be controlled according to the ambient light brightness, so that the aim of saving energy is achieved.

In some examples, the configuration of the light sensor 600 may also be slightly adjusted according to the actual situation. For example, some light sensors 600 may be densely arranged in a relatively dark road section. Thus, the luminous intensity of the traffic marking 100 can be timely controlled according to the monitored ambient light level of the road section.

Referring to fig. 10, in some examples, the intelligent road marking system may further include a pedestrian monitoring device 500 and a vehicle monitoring device 400.

In some examples, the pedestrian monitoring device 500 may be configured to monitor pedestrian signals that will pass through the traffic reticle 100.

In some examples, the vehicle monitoring device 400 may be configured to monitor vehicle signals that will pass through the traffic reticle 100.

In some examples, the control device 300 may control the power supply device 200 to supply power to the traffic marking 100 when the pedestrian monitoring device 500 monitors a pedestrian and the vehicle monitoring device 400 monitors a vehicle, so that the traffic marking 100 emits a prompt light. In this case, when the pedestrian is detected by the pedestrian detection device 500 and the vehicle is detected by the vehicle detection device 400, the power supply device 100 is caused to supply power to the traffic sign 100 under the control of the control device 300, whereby the traffic sign 100 can be caused to emit the presentation light to warn the vehicle and the pedestrian, and in a normal case, the traffic sign 100 can be caused to be in a non-light-emitting state, whereby the power consumption can be further reduced.

In some examples, the traffic marking 100 may be a zebra line that indicates the passage of pedestrians through a road.

In some examples, the vehicle monitoring device 400 may be disposed at a curb a distance from the zebra stripes. The distance may be, for example, 50 meters, 60 meters, 70 meters, 80 meters, 90 meters, 100 meters, etc. Thus, a certain inertial distance can be reserved for the type of vehicle.

In some examples, the pedestrian monitoring device 500 may be disposed on both sides of the zebra stripes. Therefore, pedestrians passing through the zebra stripes can be timely monitored.

Under the above circumstances, when a road section with a zebra crossing but without a traffic light is encountered, or a road section in darkness, a curved road section is encountered, and a vehicle is difficult to find a pedestrian in time, by the above-mentioned intelligent road marking system, it is possible to ensure that the traffic marking 100 lights a warning light in time when the vehicle is about to drive over the zebra crossing or a crosswalk while the pedestrian is about to pass over the zebra crossing, and it is possible to ensure the safe passage of the pedestrian.

This is particularly effective when the road 2 is curved and the crosswalk 1 is invisible but the notification mark is visible. Furthermore, in the evening, particularly in rainy weather, pedestrians passing through the dark crosswalk 1 without a night light are very difficult to see. The vehicle can be reliably stopped before.

In some examples, referring again to fig. 10, the intelligent road marking system may further include a first transmitter 410, a second transmitter 510, and a receiver 310.

In some examples, the first transmitter 410 may be integrated on the vehicle monitoring device 400, the second transmitter may be integrated on the pedestrian monitoring device 500, and the receiver 310 may be integrated on the control device 300. Therefore, long-distance transmission of each monitoring signal can be facilitated, and trouble caused by wire connection can be reduced.

Fig. 11 is a schematic diagram showing the connection between the power feeding device 200 and the light-emitting reticle 1 according to the example of the present embodiment.

In some examples, power supply 200 may include solar panel 210 and power store 220. Solar panel 210 may convert solar energy into electrical energy for storage in electrical storage 220. The power storage device 220 may supply power to the light emitting reticle 100 under the control of the control device 300.

In some examples, solar panel 210 may be laid on top of the road surface, or may be embedded in the road surface as is luminescent reticle 1. In some examples, solar panels 210 may be laid on a dock or a roadway in a barrier tape.

In some examples, the electrical storage device 220 may be buried under the road surface. One end of the electricity storage device 220 may be electrically connected to the solar panel 210, and the other end may be connected to the light emitting reticle 1.

In the disclosure, the intelligent road marking system formed by the control device 300, the light sensor 600, the vehicle detecting device 400, the pedestrian monitoring device 500, and the power supply device 200 composed of the solar panel 210 and the power storage device 220 can improve traffic safety, can switch the light-emitting brightness of the traffic marking according to the road environment, can save energy, and can ensure the power supply requirement of the power supply device 200 through the combination of the solar panel 210 and the power storage device 220.

While the disclosure has been described in detail in connection with the drawings and examples, it is to be understood that the foregoing description is not intended to limit the disclosure in any way. Modifications and variations of the present disclosure may be made as desired by those skilled in the art without departing from the true spirit and scope of the disclosure, and such modifications and variations fall within the scope of the disclosure.
