Description

Technical Field

[0001] This invention relates to the field of road lighting technology, and more particularly to a sidewalk supplement light and traffic road. Background Technology

[0002] Existing transportation systems typically include streetlights and other lighting components on roads to illuminate them at night. However, in some real-world scenarios, route planning and streetlight planning are not synchronized, which can lead to insufficient lighting at sidewalks on certain roads. Insufficient lighting at sidewalks can prevent drivers from seeing pedestrians in time, potentially causing traffic accidents.

[0003] Currently, supplemental lighting for sidewalks typically involves installing a floodlight on a surveillance light pole. This floodlight illuminates the sidewalk to improve its lighting. However, floodlights have a strong light diffusion effect, resulting in good illumination only in the central area, while the edges are significantly less illuminated due to light diffusion. Therefore, when using floodlights to illuminate sidewalks, only the central portion of the sidewalk is effectively lit, while other areas are poorly illuminated, leading to low light utilization. Furthermore, floodlights can cause glare when pedestrians or drivers look directly at them, reducing visual comfort and potentially causing traffic accidents due to limited visibility. Summary of the Invention

[0004] The purpose of this invention is to provide a sidewalk supplementary lighting and traffic road lighting to improve the utilization rate of light, enhance the visual comfort of people, and reduce the risk of glare.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A sidewalk supplement light includes a light-emitting element and a convex mirror disposed in front of the light-emitting element; the light-emitting element is installed on one side of the lane and located above the lane, the light-emitting element is used to illuminate the sidewalk, and the illumination direction of the light-emitting element is in the same direction as the vehicle travel direction of the corresponding lane; the convex mirror is used to focus the light generated by the light-emitting element into a predetermined illumination area.

[0007] Preferably, the convex lens has a spherical cap structure, and the upper and lower sides of the convex lens are respectively provided with tangent planes, which are horizontally arranged.

[0008] Preferably, a portion of the sidewalk is provided on the lane corresponding to the light-emitting element, and the convex mirror is used to converge the light generated by the light-emitting element to form an illumination area that matches the portion of the sidewalk on the corresponding lane.

[0009] Preferably, the edge of the lighting area is formed with a lighting cutoff line, and the illuminance within the lighting area is more than 20 times that of the area outside the lighting cutoff line;

[0010] And / or, the illuminance of light facing the supplementary light and within 10 meters of the supplementary light is greater than or equal to 30 lx.

[0011] Preferably, the installation height of the supplementary light is less than or equal to 1.2m.

[0012] Preferably, the first angle α formed between the illumination direction of the supplementary light and the horizontal plane in the vertical plane is 2~8°;

[0013] And / or, the second angle β formed by the illumination direction of the supplementary light and the vehicle travel direction in the corresponding lane on the horizontal plane is less than 45°.

[0014] Preferably, the light source also includes a heat sink located on the side of the light source away from the sidewalk, and the heat sink is in contact with the light source and dissipates heat from the light source.

[0015] A traffic road, comprising:

[0016] A lane is used for vehicles to travel on.

[0017] A sidewalk, which crosses the driveway and serves as a pedestrian passage;

[0018] Any of the above-mentioned sidewalk supplement lights are installed on one side of the driveway and used to illuminate the sidewalk.

[0019] Preferably, the lane includes a first lane and a second lane, the vehicles in the first lane and the second lane travel in opposite directions, and a portion of the pedestrian walkway is provided in the first lane and the second lane respectively;

[0020] There are two pedestrian walkway supplement lights, which are installed corresponding to the two lanes and are positioned opposite each other.

[0021] Preferably, the system also includes a post disposed on one side of the driveway, and the sidewalk supplementary lighting is fixedly installed on the post.

[0022] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0023] By using a convex mirror to focus the light from the light-emitting element, most of the light generated by the light-emitting element can be directed towards the illumination area, and the illumination effect is roughly the same everywhere in the illumination area. This effectively reduces waste caused by light diffusion, improves light utilization, and reduces energy consumption. Furthermore, by directing the diffused light source towards the illumination area, the illumination effect at the edges and the center of the illumination area can be made roughly the same, thereby achieving uniform and effective illumination of all locations in the illumination area.

[0024] By setting the illumination direction of the light-emitting element to be in the same direction as the driving direction of vehicles in the corresponding lane, drivers in the corresponding lane will not be directly facing the light-emitting element, effectively preventing the light-emitting element from causing strong light or glare to people; and when the light is restricted outside the illumination area, people will not be visually affected by the setting of the supplementary light, improving people's visual comfort and reducing the risk of traffic accidents caused by people's visual impact.

[0029] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0030] The terms used to express position and direction in this invention are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0031] like Figures 1 to 3As shown, the present invention provides a sidewalk supplement light 100, which is used to provide supplemental lighting for a sidewalk 200, thereby making it easier for drivers of vehicles on the road to observe whether there are pedestrians crossing the sidewalk 200, reducing the risk of traffic accidents caused by insufficient lighting on the sidewalk 200. The sidewalk supplement light 100 includes a light-emitting element 1 and a convex mirror 2, and may also include a heat sink 3.

[0032] Reference Figure 1 and Figure 3 The light-emitting element 1 is used to generate light that shines towards the sidewalk 200 to illuminate the sidewalk 200. The light-emitting element 1 can be a single high-power LED. The light-emitting element 1 can be connected to a power supply via a wire, so that the power supply can supply power to the light-emitting element 1 and cause it to generate illumination. The use of a high-power LED in the light-emitting element 1 allows a single LED to generate sufficient intensity of light to illuminate the sidewalk; in other embodiments, the light-emitting element 1 can also be formed by combining multiple LEDs to form an array, which is used to generate light that shines towards the sidewalk 200.

[0033] The heat sink 3 can be attached to and relatively fixed to the light-emitting element 1. The heat sink 3 can dissipate heat from the light-emitting element 1 to prevent heat buildup from affecting the light-emitting element 1 after long-term operation. The heat sink 3 is located on the side of the light-emitting element 1 away from the sidewalk 200 so that the heat sink 3 will not affect the lighting effect of the light-emitting element 1.

[0034] The convex mirror 2 is located in front of the light-emitting element 1 so that the light emitted by the light-emitting element 1 will propagate towards the convex mirror 2. The convex mirror 2 has a focusing effect. When the light emitted by the light-emitting element 1 passes through the convex mirror 2, it will be focused by the convex mirror 2 so that the light is focused by the convex mirror 2 within a certain angle range. The area within this angle range corresponds to the illumination area of ​​the sidewalk supplementary lighting 100.

[0035] After focusing the light using convex lens 2, a clear illumination cutoff line exists. The area inside the illumination cutoff line is the illuminated area, and the area outside the illumination cutoff line is the non-illuminated area. There is a significant difference in illuminance between the illuminated and non-illuminated areas, allowing them to be distinguished by the illumination cutoff line. The illumination area of ​​one sidewalk supplementary light 100 can correspond to a portion of the sidewalk 200, and multiple sidewalk supplementary lights 100 working together can effectively illuminate the entire sidewalk 200; for example, the illumination area of ​​one sidewalk supplementary light 100 can correspond to half of the sidewalk 200 adjacent to that light.

[0036] By using a convex mirror 2 to converge the light from the light-emitting element 1, most of the light generated by the light-emitting element 1 can be directed towards the illumination area, and the illumination effect is roughly the same throughout the illumination area. This effectively reduces waste caused by light diffusion, improves light utilization, and reduces energy consumption. Furthermore, directing the diffused light source towards the illumination area ensures that the illumination effect at the edges and center of the illumination area is roughly the same, thereby achieving uniform and effective illumination of all locations within the illumination area.

[0037] In this system, the light emitted by the light-emitting element 1 passes through the convex mirror 2 and is primarily contained within the illuminated area, with a small amount of light potentially diffusing into the non-illuminated area. Because the light intensity in the non-illuminated area is low, the supplementary light 100 provides weak illumination to this area, or even negligible illumination. By focusing the light within the illuminated area, the illuminated area corresponds to the location requiring illumination, i.e., the sidewalk 200 area, thus preventing the light from spreading to other locations and affecting the visibility of people in those areas.

[0038] In some specific embodiments, the convex lens 2 can be roughly in the form of a spherical cap structure, with the cross-section of the spherical cap structure facing the light-emitting element 1 and serving as the light-incident surface of the convex lens 2. In order for the convex lens 2 to effectively keep the light from the light-emitting element 1 within the illumination area, the upper and lower sides of the convex lens 2 can each form a cutting plane 21, that is, a portion of the upper and lower sides of the spherical cap structure can be cut off to form a flat cutting surface.

[0039] When the convex mirror 2 is a complete spherical cap structure, the light after being focused by the convex mirror 2 is generally a circular or nearly circular spot. However, the sidewalk 200 is generally a rectangular structure. If the illumination area formed after being focused by the convex mirror 2 is roughly circular, and the circular area completely covers the corresponding area of ​​the sidewalk 200, the supplementary light 100 will illuminate most of the area outside the sidewalk 200 at the same time, which may cause visual interference to drivers or other people outside the sidewalk 200. If the circular area is located inside the corresponding area of ​​the sidewalk 200, the supplementary light 100 will not be able to provide complete and effective illumination to the sidewalk 200.

[0040] In this application, by forming tangent planes 21 on the upper and lower sides of the convex mirror 2, the aperture of the convex mirror 2 in the vertical direction is limited, and the vertical divergence angle of the beam generated by the sidewalk supplementary lighting 100 is reduced accordingly. The projected light spot of the sidewalk supplementary lighting 100 naturally changes from a circle to an approximately rectangular or elliptical shape. Furthermore, the physical edges of the upper and lower tangent planes 21 act as an "aperture" for the light, cutting off stray refraction of light at the edge of the convex mirror 2. This results in very clear and sharp light-dark boundaries on the upper and lower sides, making the boundary of the final illuminated area clear and distinct. This effectively confines the light to the desired illuminated area and improves the utilization rate of light.

[0041] The curved portions of the upper and lower parts of the spherical surface of the original spherical structure refract some light outside the intended illumination area, resulting in wasted light energy and potentially glare. By forming tangent planes 21 on both the upper and lower sides of the convex mirror 2, these scattered light rays can be fundamentally eliminated. Therefore, the light emitted from the convex mirror 2 can be more precisely controlled within the illumination area, increasing the effective luminous flux ratio. For drivers or other observers outside the illumination area, the bright surface of the pedestrian supplementary lighting 100 is almost invisible, resulting in better visual comfort for drivers and other observers.

[0042] In addition, the tangent planes 21 formed on the upper and lower sides of the convex mirror 2 can make the beam angle narrow in the vertical direction and wide in the horizontal direction, thus forming a typical wide and flat light distribution and being able to adapt to the scene of the sidewalk 200 that requires horizontal stretching and strict vertical light control.

[0043] When the light-emitting element 1 emits light, to prevent the light emitted by the light-emitting element 1 from affecting the driver's vision, the illumination direction of the light-emitting element 1 can be in the same direction as the vehicle's travel direction in the corresponding lane 300. At this time, when the vehicle is traveling in lane 300, the driver will not face the emitting side of the light-emitting element 1, and the driver's vision will not be affected by the strong light or glare of the light-emitting element 1, reducing the safety risks when driving the vehicle.

[0044] In this configuration, the light-emitting element 1 is positioned adjacent to the corresponding lane 300, and the light emitted by the light-emitting element 1 can be focused by the convex mirror 2 onto the portion of the sidewalk 200 located in the corresponding lane 300. In other words, the illumination area of ​​the sidewalk supplementary light 100 corresponds to the portion of the sidewalk 200 located in the corresponding lane 300. At this time, the light emitted by the light-emitting element 1 will not significantly affect the vision of pedestrians in other lanes. By setting the light-emitting element 1 to travel in the same direction as the vehicles in the corresponding lane, it is possible to effectively prevent the light-emitting element 1 from causing strong light irradiation or glare to pedestrians.

[0045] In some specific embodiments, there may be two lanes 300 on the road, with vehicles traveling in opposite directions on the two lanes 300. A pedestrian walkway 200 may cross both lanes 300, with part of the pedestrian walkway 200 located on one lane 300 and part on the other. Each lane 300 may be equipped with a corresponding pedestrian auxiliary light 100, which is installed on one side of the corresponding lane 300 and used to illuminate the pedestrian walkway 200 located in that lane 300.

[0046] The illumination area of ​​the pedestrian supplement light 100 can be adapted to the outline of the pedestrian walkway 200 on the corresponding lane 300. For example, the length and width of the illumination area of ​​the pedestrian supplement light 100 are the same as or approximately the same as the length and width of the outline of the pedestrian walkway 200 on the corresponding lane 300. Specifically, the width of the illumination area of ​​the pedestrian supplement light 100 can be 1.0 to 1.2 times the width of the outline of the pedestrian walkway 200 on the corresponding lane 300, and the length of the illumination area of ​​the pedestrian supplement light 100 can be 1.0 to 1.2 times the length of the outline of the pedestrian walkway 200 on the corresponding lane 300. The width direction of the illumination area and the width direction of the pedestrian walkway 200 can be parallel to the extension direction of the lane 300, and the width direction of the illumination area and the length direction of the pedestrian walkway 200 can be parallel to the width direction of the lane 300.

[0047] By adapting the illumination area of ​​the pedestrian supplement light 100 to the outline of the pedestrian walkway 200 on the corresponding lane 300, the pedestrian supplement light 100 illuminates the pedestrian walkway 200 on the corresponding lane 300, and the pedestrian supplement light 100 has virtually no impact on the illumination of the other lane 300. At this time, the driver traveling in the other lane 300 will not be affected by the supplement lights 100 corresponding to different lanes 300, further reducing the safety risks when driving.

[0048] In some specific embodiments, when facing the supplementary light 100, the illuminance produced by the supplementary light 100 within a distance of 10m can be no less than 30lx to ensure that the supplementary light 100 has sufficient lighting effect. Furthermore, when facing the supplementary light 100 at the same distance, the illuminance of the light within the illuminated area of ​​the same supplementary light 100 is more than 20 times that outside the illuminated area, so that the supplementary light 100 can produce an effective lighting effect in the illuminated area that needs illumination, while producing virtually no lighting effect in the non-illuminated areas of the supplementary light 100.

[0049] To reduce the visual impact of the supplementary lighting 100 on pedestrians, the installation height H of the supplementary lighting 100 can be less than 1.2m, meaning the vertical distance between the highest point of the supplementary lighting 100 and the road is less than or equal to 1.2m. Most pedestrians walking on the sidewalk 200 are taller than 1.2m. By limiting the installation height H of the supplementary lighting 100 to less than 1.2m, most pedestrians will not have their line of sight directly facing the supplementary lighting 100, and most pedestrians will not experience glare from the illumination of the supplementary lighting 100. Furthermore, the installation height H of the supplementary lighting 100 can be adjusted as needed to minimize glare for pedestrians of corresponding heights walking on the sidewalk 200. Preferably, the installation height H of the supplementary light 100 can be 1m or less. In this case, the glare problem of pedestrians taller than 1m when walking on the sidewalk 200 can be solved. Those shorter than 1m are generally children under 4 years old. These children are usually taken care of by their elders. Therefore, setting the installation height H of the supplementary light 100 to less than or equal to 1m can effectively reduce the safety problems caused by glare from pedestrians while illuminating the sidewalk 200.

[0050] In some specific embodiments, the supplementary light 100 is positioned on one side of the corresponding lane 300, and the illumination direction of the supplementary light 100 is tilted downwards so that the light generated by the supplementary light 100 can illuminate the corresponding area of ​​the sidewalk 200. The first angle α formed between the illumination direction of the supplementary light 100 and the horizontal plane in the vertical plane is less than or equal to 15°, preferably 2~8°. When the installation height H of the supplementary light 100 is low, by reducing the first angle α formed between the supplementary light 100 and the horizontal plane, the width of the illuminated area generated by the supplementary light 100 can be effectively stretched, thereby allowing the illuminated area generated by the supplementary light 100 to correspond to the size of the corresponding area of ​​the sidewalk 200.

[0051] When the supplementary light 100 is installed on one side of the corresponding lane 300, in addition to being tilted downwards, the supplementary light 100 also needs to be tilted horizontally towards the lane 300 so that the illumination area generated by the supplementary light 100 falls on the corresponding area of ​​the sidewalk 200 located on the lane 300. The second angle β formed by the illumination direction of the supplementary light 100 and the vehicle travel direction of the corresponding lane 300 in the horizontal plane can be less than 45°. By limiting the angle value of the second angle β between the supplementary light 100 and the vehicle travel direction of the corresponding lane 300, it is possible to effectively prevent the light generated by the supplementary light 100 from propagating to the other lane 300 and affecting the viewing angle of people in the other lane 300; furthermore, limiting the angle value of the second angle β also allows the light to diffuse more gently into the corresponding lane 300, improving the visual comfort of people in the corresponding lane 300. In this lane, the vehicles in the lane 300 corresponding to the supplementary light 100 travel in the same direction as the illumination direction of the supplementary light 100, while the vehicles in the other lane 300 travel in the opposite direction to the illumination direction of the supplementary light 100.

[0052] Reference Figure 1 and Figure 2 The present invention also provides a traffic road, including a lane 300 for vehicles, a sidewalk 200 that crosses the lane 300 for pedestrians, pillars 400 set on both sides of the lane 300, and the aforementioned sidewalk supplement lights 100.

[0053] The sidewalk supplementary lighting 100 can be fixedly installed on the post 400 and illuminate the corresponding area of ​​the sidewalk 200. The post 400 can be hollow internally and have light-transmitting holes facing the sidewalk 200, with the sidewalk supplementary lighting 100 installed inside the post 400 and exposed to the outside through the light-transmitting holes; alternatively, the sidewalk supplementary lighting 100 can be directly fixedly installed on the surface of the post 400. Two sidewalk supplementary lighting 100s can be provided, with each pair installed on opposite sides of the driveway 300, and the sidewalk supplementary lighting 100s on the left and right sides of the driveway 300 can be positioned opposite each other.

[0054] As a specific example, lane 300 includes a first lane 301 and a second lane 302. Vehicles in the first lane 301 travel from left to right, and vehicles in the second lane 302 travel from right to left. A pedestrian auxiliary light 100 is installed on the side of the first lane 301 opposite to the second lane 302. The pedestrian auxiliary light 100 is located on the left side of the pedestrian walkway 200, and its illumination direction is from left to right. The pedestrian auxiliary light 100 is used to illuminate the portion of the pedestrian walkway 200 located in the first lane 301. Another pedestrian auxiliary light 100 is installed on the side of the second lane 302 opposite to the first lane 301. The pedestrian auxiliary light 100 is located on the right side of the pedestrian walkway 200, and its illumination direction is from right to left. The pedestrian auxiliary light 100 is used to illuminate the portion of the pedestrian walkway 200 located in the second lane 302.

[0055] By setting the illumination direction of the supplementary light 100 to be in the same direction as the vehicles traveling in the corresponding lane 300, drivers in the corresponding lane 300 will not be directly facing the supplementary light 100, thus minimizing glare for them. Furthermore, the illumination area of ​​the supplementary light 100 is limited to the corresponding lane 300 by the convex mirror 2 and will not illuminate the other lane 300, so drivers in the other lane 300 will also be largely unaffected by the supplementary light 100. Therefore, by setting up two pedestrian supplementary lights 100, the pedestrian crossing 200 that crosses the two lanes 300 can be effectively illuminated, and drivers of passing vehicles will not experience glare from the supplementary lights 100, ensuring traffic safety.

[0056] The pillars 400 set on both sides of the lane 300 can be support pillars for structures such as traffic warning signs, street lights, and billboards. The sidewalk supplementary lights 100 can be fixedly installed on the support pillars of the traffic warning signs, street lights, and billboards. Alternatively, when there are no traffic warning signs, street lights, billboards, or other structures in the area where the sidewalk supplementary lights 100 need to be installed, a pillar 400 can be set up by oneself, and the sidewalk supplementary lights 100 can be installed on the self-set pillar 400.

[0057] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
