Description

Technical Field

[0001] This invention relates to the field of security monitoring technology, and in particular to a traffic supplement light and camera device. Background Technology

[0002] Traffic auxiliary lights are facilities that provide supplemental lighting for vehicles traveling on highways. They are often used in conjunction with road surveillance cameras. The traffic auxiliary lights illuminate the license plates, bodies, and occupants of passing vehicles, and the road surveillance cameras capture images of the vehicles, license plates, and occupants. Typically, traffic auxiliary lights are installed on high-altitude cantilevered scaffolds above the road surface, and the emitted light is projected onto the road surface at a relatively horizontal downward angle.

[0003] The current problem is that when a vehicle is in motion, the license plate passes over the overhead cantilever before the driver and passengers. The distance and angle between the license plate and the traffic auxiliary lights are different from those between the driver and passengers and the traffic auxiliary lights. As a result, there is a differential illuminance distribution in the illuminated area (i.e., the area of ​​light spot projection) on the vehicle. The illuminance of the area relatively closer to the traffic auxiliary lights is greater than that of the area relatively farther away from the traffic auxiliary lights. This leads to excessive illuminance at the license plate area, resulting in overexposure, while the illuminance of the driver and passengers is too weak, resulting in a dim image. Summary of the Invention

[0004] In view of this, the present invention provides a traffic supplement light that, when illuminating a moving vehicle, can suppress the difference in illuminance distribution in the illuminated area of ​​the vehicle, reduce the illuminance at the license plate and increase the illuminance at the position of the driver and passengers, so that the road monitoring camera that is paired with it can obtain a clear vehicle image.

[0005] The traffic supplementary lighting provided by the present invention includes a light-emitting component and a beam-beaming component. The light-emitting component includes a lamp body, and the beam-beaming component includes a first reflector and has a light outlet. The first reflector includes a first fusion reflector and a polarizing reflector, both located on the light-emitting side of the lamp body. The first fusion reflector is used to reflect part of the light from the lamp body, and the light reflected by the first fusion reflector is fused with part of the light directly emitted from the light outlet of the lamp body to form a far supplementary beam. The polarizing reflector is used to reflect part of the light from the lamp body, and the light reflected by the polarizing reflector is polarized with part of the light directly emitted from the light outlet of the lamp body to form a near supplementary beam. The intensity of the near supplementary beam does not exceed the intensity of the far supplementary beam.

[0006] In one embodiment, the far-field beam and the near-field beam can be projected onto the road surface respectively, forming a second bright area and a third bright area that are sequentially arranged and adjacent to each other along the driving direction specified by the road surface, wherein the illuminance of the third bright area is not greater than the illuminance of the second bright area.

[0007] With this setup, there will be no dark areas between the second and third bright areas, or areas with lower illumination than the second or third bright areas. This allows the second and third bright areas to form a complete light spot. As a result, when the traffic auxiliary lights shine on the vehicle, there will be no shadows in the vehicle image captured by the road monitoring camera, ensuring that the front of the vehicle, the license plate, and the driver and passengers are all illuminated.

[0008] In one embodiment, the optical axis of the lamp body extends to the light outlet; along the direction of the lamp body pointing to the light outlet, a first fusion reflector and a polarizing reflector are arranged in sequence; the side wall of the polarizing reflector near the optical axis is inclined relative to the side wall of the first fusion reflector near the optical axis in the direction of the optical axis, and the distance between the polarizing reflector and the side wall near the optical axis and the optical axis tends to decrease along the direction of the lamp body pointing to the light outlet.

[0009] With this setup, the light reflected from the polarized reflector can be better directed towards the front of the vehicle compared to the light directly emitted by the lamp body. Furthermore, the angle of incidence of this light on the license plate is smaller, which helps to alleviate overexposure of the license plate. The areas illuminated by the near beam and the far beam can transition smoothly and gradually without clear boundaries of illuminance differences, resulting in a balanced illuminance distribution within the light spot area.

[0010] In one embodiment, the first reflector further includes a first enhanced reflective part, which is used to reflect part of the light from the lamp body. The light reflected by the first enhanced reflective part is combined with part of the light emitted directly from the light outlet of the lamp body to form an enhanced supplementary beam; wherein the intensity of the far supplementary beam does not exceed that of the enhanced supplementary beam.

[0011] With this setup, the traffic auxiliary lights form more beam branches. The enhanced auxiliary beam not only makes the beam angle of the light emitted from the light outlet larger, further expanding the illumination range and the size of the light spot formed by the traffic auxiliary lights, but more importantly, the enhanced auxiliary beam can make up for the limited illumination range of the far auxiliary beam. It can also provide supplementary lighting for the occupants inside the vehicle, thereby meeting the supplementary lighting needs of vehicles of different sizes and types.

[0012] In one embodiment, the enhanced supplementary beam can be projected onto the road surface to form a first bright area. The first bright area, the second bright area, and the third bright area are arranged sequentially and adjacent to each other along the driving direction specified by the road surface. The illuminance of the second bright area is not greater than the illuminance of the first bright area; and / or, the illuminance of the third bright area is not greater than the illuminance of the second bright area.

[0013] This configuration ensures that there are no dark areas, or areas with lower illumination than the second or third bright areas, between the first and second bright areas, thus forming a complete and larger light spot. When the traffic lights illuminate vehicles, the images captured by the road monitoring cameras will not show any bright area gaps or shadows, ensuring that all objects within the field of view are illuminated.

[0014] In one embodiment, the optical axis of the lamp body extends to the light outlet. Along the direction of the lamp body pointing to the light outlet, a first enhanced reflective part and a first fused reflective part are arranged in sequence. The side wall of the first enhanced reflective part near the optical axis is inclined relative to the side wall of the first fused reflective part near the optical axis in the direction of the optical axis. The distance between the side wall of the first enhanced reflective part near the optical axis and the optical axis tends to increase along the direction of the lamp body pointing to the light outlet.

[0015] With this configuration, compared to the light emitted directly from the lamp body and the light reflected by the first fused reflector, the light reflected by the first enhanced reflector can be projected to a farther position, thus better diffusing towards the rear of the vehicle, including the engine hood, driver's cab, and sunroof. This portion of light has a larger angle of incidence when it reaches the occupants, which helps to improve the illuminance for the occupants and alleviate the underexposure problem in the driver's cab. The illuminance of the area illuminated by the enhanced supplementary beam and the area illuminated by the far supplementary beam can transition smoothly and gradually, without any clear boundary between illuminance differences, resulting in a more balanced illuminance distribution within the light spot area.

[0016] In one embodiment, the sidewall of the first fused reflective portion near the optical axis is connected to the sidewall of the polarized reflective portion near the optical axis via a curved transition; and / or, the sidewall of the first enhanced reflective portion near the optical axis is connected to the sidewall of the first fused reflective portion near the optical axis via a curved transition.

[0017] With this setup, in the area where the vehicle or road surface is illuminated, the illuminance of the area illuminated by the enhanced supplementary beam and the area illuminated by the far supplementary beam have a smooth transition, and the illuminance of the area illuminated by the far supplementary beam and the area illuminated by the near supplementary beam have a smooth transition, so that there will be no clear boundary between illuminance differences in the light spot formed in the end.

[0018] In one embodiment, the first enhanced reflective portion, the first fused reflective portion, and the polarized reflective portion are integrally formed; or, the first enhanced reflective portion, the first fused reflective portion, and the polarized reflective portion are separately formed and spliced ​​and fixed into one unit.

[0019] With this configuration, when the first reflector is a one-piece molded part, the overall rigidity of the first reflector can be improved; when the first reflector is made of multiple split-formed structures and fixed by splicing, the shape and size accuracy of the first reinforced reflector, the first fused reflector and the polarized reflector can be controlled one by one to ensure that the direction and angle of the light reflected by different reflectors of the first reflector meet the design expectations.

[0020] In one embodiment, the intensities of the near-compensation beam, the far-compensation beam, and the enhanced compensating beam increase sequentially, wherein the spatial region occupied by the far-compensation beam is located between the spatial region occupied by the near-compensation beam and the spatial region occupied by the enhanced compensating beam.

[0021] With this setup, when the traffic auxiliary lights project light onto the road surface or vehicle, the resulting light spots can show a trend of increasing illuminance in one direction. The areas illuminated by the near auxiliary beam, the areas illuminated by the far auxiliary beam, and the areas illuminated by the enhanced auxiliary beam gradually increase in illuminance, which can be better suited for use in vehicle auxiliary lighting scenarios and meet the differentiated and gradual auxiliary lighting needs of different vehicle positions.

[0022] In one embodiment, the beam beam assembly further includes a hollow lampshade, which includes a first reflector and a light outlet at one end of the hollow lampshade, the edge of which is quadrilateral.

[0023] With this configuration, the area of ​​the road surface illuminated by the traffic auxiliary lights is quadrilateral. This ensures that the frontal outline of the vehicle is illuminated while avoiding the waste of light by illuminating other objects that do not need to be illuminated. It better matches the supplementary lighting needs within the rectangular target field of view and improves the light efficiency of the traffic auxiliary lights.

[0024] In one embodiment, the edge of the light outlet is trapezoidal in shape, and the edge of the light outlet includes two parallel sides. The end of the first reflector that is relatively far from the lamp body participates in forming the shorter of the two parallel sides of the light outlet edge.

[0025] With this configuration, when the position of the first reflector in the traffic supplement light is set to the side of the traffic supplement light that is relatively far from the ground, and the tilt angle of the traffic supplement light relative to the road surface is adjusted, the light emitted from the light outlet can be projected onto the road surface to form a rectangular light spot. The rectangular light spot can fully meet the supplementary lighting needs of the rectangular field of view area, and can fully illuminate the front of the vehicle, avoiding insufficient local illumination.

[0026] In one embodiment, the beam beam assembly further includes a second reflector, which is arranged at a distance from the first reflector and faces it. The second reflector is used to reflect part of the light from the lamp body. The light reflected by the second reflector is combined with part of the light emitted directly from the light outlet of the lamp body to form a far-field beam and an enhanced beam.

[0027] With this configuration, the light reflected by the second reflector can illuminate the vehicle's cab and occupants together with the light emitted directly from the lamp body, thus making it easier for the road monitoring camera to obtain clearer images of the cab interior and occupants.

[0028] In one embodiment, the optical axis of the lamp body extends to the light outlet, and the second reflector includes a second fusion reflector. Along the direction of the lamp body pointing to the light outlet, the distance between the second fusion reflector and the optical axis tends to increase. The second reflector is used to reflect part of the light from the lamp body. The light reflected by the second fusion reflector is fused with part of the light directly emitted from the light outlet of the lamp body to form a far-compensation beam.

[0029] With this configuration, the second fusion reflector participates in the formation of the far-compensation beam by reflecting the light from the lamp body, thereby compensating for the energy of the light reflected by the first fusion reflector and helping to improve the energy intensity of the far-compensation beam.

[0030] In one embodiment, the second reflector further includes a second enhanced reflector, which is arranged in the direction of the lamp body pointing towards the light outlet. The second fusion reflector and the second enhanced reflector are arranged sequentially. The side wall of the second enhanced reflector near the optical axis is inclined relative to the side wall of the second fusion reflector near the optical axis in the direction near the optical axis. The distance between the side wall of the second fusion reflector near the optical axis and the optical axis tends to increase. The second enhanced reflector is used to reflect light from the lamp body. The light reflected by the second enhanced reflector is merged with part of the light directly emitted from the light outlet of the lamp body to form an enhanced supplementary beam.

[0031] With this configuration, the second enhanced reflector participates in the formation of the enhanced supplementary beam by reflecting the light from the lamp body, thereby compensating for the energy of the light reflected by the first enhanced reflector and helping to improve the energy intensity of the enhanced supplementary beam.

[0032] In one embodiment, the beam beam assembly further includes a third reflector and a fourth reflector, which are located between the first reflector and the second reflector and together with the first reflector and the second reflector to form a hollow lampshade; at least one of the third reflector and the fourth reflector can move relatively closer to or further away from the other to change the shape of the light outlet.

[0033] With this configuration, all light can only be emitted from the light outlet, avoiding light waste and further improving the luminous efficiency of traffic supplementary lights. Traffic supplementary lights can change the shape of the light spot they illuminate on the road or vehicles by changing the shape of the light outlet. The adjustable light spot shape means that traffic supplementary lights can adapt to the supplementary lighting needs of different shaped or sized field areas, as well as the supplementary lighting needs after the field area has shifted.

[0034] In one embodiment, the lamp body includes a light-emitting body, and further includes a collimating reflector. The collimating reflector has a collimating cavity with an opening facing the light outlet. The light-emitting body is disposed within the collimating cavity. The light received by the first reflector includes collimated reflected light, which is formed by reflecting a portion of the light from the light-emitting body through the collimating reflector. And / or, the lamp body also includes a lens disposed on the side of the light-emitting body facing the light outlet. The light received by the first reflector includes lens-refracted light, which is formed by refraction of a portion of the light from the light-emitting body through the lens.

[0035] With this configuration, both the collimating reflector and the lens are designed so that the light emitted by the light source is used as much as possible to project out of the light outlet and illuminate passing vehicles. This ensures that the energy of the formed light spot and each bright area meets the needs of vehicle lighting, avoids the waste of energy caused by some of the light from the light source not being utilized, improves the utilization rate of the light emitted by the light source, and thus improves the luminous efficiency of the traffic supplementary lights.

[0036] The present invention also provides a camera device, including a camera and the traffic supplement light provided by the present invention, the traffic supplement light being used to provide supplementary lighting for the target being photographed by the camera.

[0037] Compared with existing technologies, this invention utilizes a first reflector to reflect the received incident light rays in a multi-angle, multi-directional divergent manner, achieving on-demand energy distribution of the light beam illuminating different parts of the vehicle. The near-compensation beam formed by the polarizing reflector is responsible for supplementing the license plate illumination, while the light reflected by the first fusion reflector, combined with the light rays directly emitted from the lamp body, forms a far-compensation beam responsible for supplementing the illumination of the driver and passengers. The energy relationship between the near-compensation beam and the far-compensation beam ensures that the illuminance of the license plate is not greater than that of the driver and passengers, overcoming the defect of license plate illuminance being greater than that of the driver and passengers that easily occurs when using existing similar products. This can improve the problem of overexposed license plates and underexposed drivers and passengers when photographing passing vehicles on the road, and is conducive to obtaining higher quality vehicle images for road monitoring cameras used in conjunction with traffic supplementary lights, ensuring that both the license plate and the driver and passengers are clearly distinguishable.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] This invention provides a traffic supplement light 100, which is a facility for providing supplemental lighting to vehicles 300 on highways. It is typically installed high above the road surface 200 together with a road monitoring camera, and the two are used in conjunction. The traffic supplement light 100 illuminates the license plate 310, body, and occupants of passing vehicles 300, while the road monitoring camera captures images of the vehicles 300, license plate 310, and occupants.

[0051] Please see Figures 1-2 The traffic supplementary lighting 100 provided by the present invention includes a fixedly installed light-emitting component 10 and a beam-beaming component 20. The light-emitting component 10 includes a driving unit 12 and a lamp body 11 connected to one end of the driving unit 12. The lamp body 11 includes a light-emitting element 112 electrically connected to the driving unit 12. The specific type of the light-emitting element 112 is not limited, and it can be a flash lamp, a halogen lamp, or a xenon lamp. The shape of the light-emitting element 112 is also not specifically limited, and it can be spherical, hemispherical, conical, cylindrical, frustum-shaped, or truncated cone, etc. The driving unit 12 includes a driving power supply for supplying power to the light-emitting element 112, a circuit unit for connecting the driving power supply and the lamp body 11, and a heat dissipation device for cooling the driving power supply and the circuit unit.

[0052] The beam-beaming assembly 20 includes a hollow lampshade, which adjusts and concentrates the direction / angle of the light emitted by the lamp body 11. The direction of the light emitted by the lamp body 11 is divergent and not unique. For example, when the light source 112 has a spherical structure, the light is distributed radially around the center of the sphere. The hollow lampshade can concentrate the divergent light in a certain direction or angle so that as much light as possible can illuminate the target area approximately along that direction / angle.

[0053] See Figure 2The lamp body 11 also includes a collimating reflector 113 fixedly connected to the driving unit 12. The collimating reflector 113 has a hollow interior forming a collimating reflective cavity 1131. One end has a splicing interface 1133 communicating with the collimating reflective cavity 1131, and the other end has a lamp body mounting hole 1132 communicating with the collimating reflective cavity 1131. The light emitter 112 extends into the lamp body mounting hole 1132 and is located inside the collimating reflective cavity 1131. At the same time, the optical axis of the light emitter 112, that is, the optical axis 111 of the lamp body 11, extends out of the splicing interface 1133. The end of the collimating reflector 113 with the lamp body mounting hole 1132 is fixedly connected to the driving unit 12. The inner wall of the collimating reflective cavity 1131 reflects the light emitted by the lamp body 11, thereby changing the direction and angle of the light illumination.

[0054] The optical axis 111 is an imaginary ray that passes through the center of the light emitter 112, and its extension direction is approximately the projection direction after the light beam is focused and concentrated by the beam-focusing assembly 20. After the light from the light emitter 112 is reflected by the inner wall of the collimating reflector cavity 1131, its angle relative to the optical axis 111 does not exceed a preset upper limit of the divergence angle. Therefore, the inner wall of the collimating reflector cavity 1131 can make the light beam as parallel to the optical axis 111 as possible. Optionally, the shape of the collimating reflector cavity 1131 can be a conical surface, a frustum, a spherical cap, a parabolic surface, etc. Figure 2 In the traffic supplement light 100 shown, the inner wall of the collimating reflector cavity 1131 is spherical.

[0055] The hollow area inside the hollow lampshade forms a beaming cavity 253, which passes through both ends of the hollow lampshade to form a light inlet 251 and a light outlet 252. The edge of the light inlet 251 has the same shape as the edge of the splicing interface 1133 and is fixedly connected, forming a sealed fit between them. The light outlet 252 is located at the end of the hollow lampshade that is relatively far away from the light-emitting component 10, and is used to release light and define the initial illumination range of the light. The initial illumination range of the light determines the shape of the light spot formed by the light projected onto the road surface 200. The optical axis 111 of the lamp body 11 extends in the beaming cavity 253 and extends out of the light outlet 252.

[0056] Specifically, please refer to Figure 1 The hollow lampshade includes a first reflector 21 and a second reflector 22 that are arranged facing each other and spaced apart, and a third reflector 23 and a fourth reflector 24 located between the first reflector 21 and the second reflector 22. The four reflectors together form a beam cavity 253. When the hollow lampshade is fixedly connected to the collimating reflector 113, the inner wall of the beam cavity 253 is closed along the circumference of the optical axis 111. That is, the first reflector 21, the second reflector 22, the third reflector 23 and the fourth reflector 24 are tightly fitted together, so that the light entering the beam cavity 253 from the light inlet 251 can only be emitted from the light outlet 252 and will not overflow from the side wall of the hollow lampshade.

[0057] The ends of the first reflector 21, the second reflector 22, the third reflector 23, and the fourth reflector 24, all located away from the light outlet 252, together form the edge of the light inlet 251. All four reflectors are fixedly connected to the collimating reflector 113 at the edge of the splicing interface 1133. In other embodiments, the hollow lampshade may also be fitted with the collimating reflector 113 and fixedly connected to its outer peripheral wall.

[0058] Furthermore, the lamp body 11 also includes a lens 114, which is a spherical transparent light guide structure. The spherical surface of the lens 114 protrudes along the direction from the light-emitting body 112 to the light outlet 252, and is positioned opposite to the light-emitting body 112. The lens 114 can converge and collimate the light emitted from the light-emitting body 112, especially the light that does not reach the collimating reflector 1131. When the collimating reflector 1131 is conical, spherical, or parabolic, the axis of the inner wall of the collimating reflector 1131 can be coaxial with the axis of the lens 114. In addition, the optical axis of the lamp body 11 (i.e., the optical axis 111 of the light-emitting body 112) can be coaxial with the axis of the lens 114, or form a suitable angle with the axis of the lens 114, such as... Figure 2 The traffic supplement light 100 shown can be used as long as the optical axis 111 of the lamp body 11 can extend out of the light outlet 252.

[0059] Furthermore, the lamp body 11 also includes a lens holder 115 made of transparent material. The lens 114 can be fixed to the hollow lampshade and / or collimating reflector 113 via the lens holder 115. The lens holder 115 can not only fix the lens 114 to maintain the relative position between the light source 112 and the lens 114, but also refract the light reflected by the collimating reflector 113 through the lens holder 115, and the refracted light can be closer to the optical axis 111, so that the direction of the light is more concentrated. The lens holder 115 can be set as a circular ring plate structure, so as to refract the light reflected by the inner wall of the collimating reflector cavity 1131 within the circumference of the optical axis 111.

[0060] The traffic supplement light 100 illuminates a bright spot area on the road surface 200. When a vehicle 300 enters this bright spot area, the light forms spots on the vehicle body, license plate 310, driver's cabin, and passengers. To avoid overexposure of the license plate 310 due to excessive illuminance, and to overcome dim and blurry images caused by insufficient illuminance in the driver's cabin and among the passengers, the traffic supplement light 100 of this invention has the following improvements:

[0061] Along the direction from the lamp body 11 to the light outlet 252, the first reflector 21 includes a first fusion reflector 212 and a polarizing reflector 213 arranged sequentially. Both are located on the light-emitting side of the lamp body 11, specifically on the side of the light-emitting body 112 facing the light outlet 252 and away from the driving unit 12. The first fusion reflector 212 reflects a portion of the light from the lamp body 11. The light reflected from the light outlet 252 by the first fusion reflector 212 merges with a portion of the light directly emitted from the light outlet 252 by the lamp body 11, forming a far-compensation beam 372. The polarizing reflector 213 reflects a portion of the light from the lamp body 11. The light reflected from the light outlet 252 by the polarizing reflector 213 merges with a portion of the light directly emitted from the light outlet 252 by the lamp body 11, forming a near-compensation beam 371.

[0062] The light reflected by the first fusion reflector 212 includes light emitted from the light source 112, refracted through the lens 114 and / or lens holder 115, and then reaching the first fusion reflector 212; it also includes light emitted from the light source 112, first projected onto the collimating reflector 113, and then reflected by the collimating reflector 113 back to the first fusion reflector 212. Similarly, the light reflected by the polarizing reflector 213 includes light emitted from the light source 112, refracted through the lens 114 and / or lens holder 115, and then reaching the polarizing reflector 213; it also includes light emitted from the light source 112, first projected onto the collimating reflector 113, and then reflected by the collimating reflector 113 back to the polarizing reflector 213.

[0063] After the traffic supplement light 100 is installed, the road surface area illuminated by the near supplement light beam 371 is closer to the traffic supplement light 100, while the road surface area illuminated by the far supplement light beam 372 is farther from the traffic supplement light 100.

[0064] Optionally, the energy intensity of the near-compensation beam 371 can be less than or equal to the energy intensity of the far-compensation beam 372, as long as the energy intensity of the near-compensation beam 371 is not greater than the energy intensity of the far-compensation beam 372.

[0065] Once the traffic auxiliary lights 100 are installed, the illuminance of the road surface area illuminated by the near-beam 371 will not be greater than the illuminance of the road surface area illuminated by the far-beam 372. In some embodiments, the far-beam 372 and the near-beam 371 can be projected onto the road surface respectively, forming a second and a third bright area that are sequentially arranged and adjacent along the prescribed driving direction of the road surface, wherein the illuminance of the third bright area is not greater than the illuminance of the second bright area.

[0066] Specifically, the first fusion reflector 212 has a first fusion reflective inner wall near the optical axis 111 and used to form the inner wall of the beam cavity 253, and the polarization reflector 213 has a polarization reflective inner wall near the optical axis 111 and used to form the inner wall of the beam cavity 253. The polarization reflective inner wall is inclined relative to the first fusion reflective inner wall in the direction near the optical axis 111, such as... Figure 2 as well as Figure 5 As shown, the distance between the inner wall of the polarization reflection and the optical axis 111 decreases along the direction from the lamp body 11 to the light outlet 252; the maximum distance between the inner wall of the polarization reflection and the optical axis 111 is not greater than the minimum distance between the inner wall of the first fusion reflection and the optical axis 111.

[0067] Furthermore, in some embodiments, the first reflector 21 further includes a first enhanced reflector 211, which is also located on the light-emitting side of the lamp body 11. The first enhanced reflector 211 is used to reflect part of the light from the lamp body 11, and the light reflected by the first enhanced reflector 211 can be combined with part of the light emitted directly from the light outlet 252 of the lamp body 11 to form an enhanced supplementary beam 373.

[0068] After the traffic supplement light 100 is installed, the road surface area illuminated by the enhanced supplement beam 373 is farther away from the traffic supplement light 100, and is farther away from the road surface area illuminated by the far supplement beam 372 than the traffic supplement light 100.

[0069] Optionally, the enhanced supplementary beam 373 can be projected onto the road surface to form a first bright area. The illuminance of the second bright area is no greater than that of the first bright area, and the illuminance of the third bright area is no greater than that of either the second or first bright area. The first, second, and third bright areas are sequentially arranged and adjacent to each other along the prescribed driving direction of the road surface, forming a complete bright spot. The reason why the illuminance of the third, second, and first bright areas is preferably set to increase sequentially is that: the ability of drivers and passengers, especially their faces, to reflect light is weaker than that of license plates and vehicle bodies. When a uniformly intense supplementary beam is simultaneously projected onto the license plate and drivers and passengers, the image of the face may still be darker than that of the license plate. Therefore, the energy of the far-field supplementary beam and the enhanced supplementary beam, which mainly participate in illuminating the driver and passengers, is controlled to be higher than that of the near-field supplementary beam. This can offset the adverse effect of the low reflectivity of the human face. At the same time, since the license plate has a stronger reflectivity, even if the energy of the near-field supplementary beam is moderately reduced, it will not affect the imaging brightness of the license plate. Moreover, it is not necessary to increase the total power consumption of the light-emitting body 112, thus realizing the on-demand allocation of the beam energy illuminating different parts of the vehicle.

[0070] The light reflected by the first enhanced reflective part 211 includes light emitted by the light source 112, refracted through the lens 114 and the lens support 115, and then reaching the first enhanced reflective part 211. It also includes light emitted by the light source 112, first projected onto the collimating reflector 113, and then reflected by the collimating reflector 113 to the first enhanced reflective part 211.

[0071] Specifically, along the direction from the lamp body 11 to the light outlet 252, the first enhanced reflector 211 and the first fused reflector 212 are arranged sequentially. The first enhanced reflector 211 has a first enhanced reflective inner wall near the optical axis 111 and used to form the inner wall of the beam cavity 253. The first enhanced reflective inner wall is inclined relative to the first fused reflective inner wall in the direction near the optical axis 111, such as... Figure 2 and Figure 5 As shown, the distance between the first enhanced reflective inner wall and the optical axis 111 increases along the direction from the lamp body 11 to the light outlet 252.

[0072] Therefore, in the direction from the lamp body 11 to the light outlet 252, the first reinforcing reflective inner wall of the first reinforcing reflective part 211, the first fusion reflective inner wall of the first fusion reflective part 212, and the polarization reflective inner wall of the polarization reflective part 213 form a rising-falling undulating segment. The distance between the rising-falling undulating segment and the optical axis 111 shows a trend of first increasing and then decreasing in the direction from the lamp body 11 to the light outlet 252.

[0073] Optionally, the maximum distance between the first reinforcing reflective inner wall and the optical axis 111 is not greater than the minimum distance between the first fused reflective inner wall and the optical axis 111; the first fused reflective inner wall and the polarized reflective inner wall can be smoothly connected by a curved surface transition, and the first reinforcing reflective inner wall and the first fused reflective inner wall can also be smoothly connected by a curved surface transition; the first fused reflective inner wall may include multiple interconnected planes with gradually changing tilt angles relative to the optical axis 111, and the first reinforcing reflective inner wall may include multiple interconnected planes with gradually changing tilt angles relative to the optical axis 111, and the polarized reflective inner wall may include multiple interconnected planes with gradually changing tilt angles relative to the optical axis 111. Of course, the first reinforcing reflective inner wall, the first fused reflective inner wall, and the polarized reflective inner wall can also be configured as curved surfaces.

[0074] Optionally, when the first reinforcing reflective inner wall is curved, it has a center of curvature located on the side of the first reinforcing reflective portion 211 near the optical axis 111; when the first fusion reflective inner wall is curved, it has a center of curvature located on the side of the first fusion reflective portion 212 near the optical axis 111; and when the polarizing reflective inner wall is curved, it has a center of curvature located on the side of the polarizing reflective portion 213 near the optical axis 111. With this configuration, the height variation of the rising-falling undulation segment relative to the optical axis 111 is gentle and gradual, helping to eliminate the illuminance difference boundary of the final formed light spot. This results in a uniform and gentle transition in the illuminance distribution within each of the first, second, and third bright areas, and also a more balanced and gentler transition in the illuminance distribution at the junction of adjacent bright areas.

[0075] Optionally, the first reinforcing reflective part 211, the first fused reflective part 212, and the polarized reflective part 213 are fixedly connected as a single unit. The first reinforcing reflective part 211, the first fused reflective part 212, and the polarized reflective part 213 can be integrally formed, meaning the first reflective part 21 can be obtained using an integral forming process, or it can be obtained through a split forming process and then assembled and fixed to form the first reflective part 21. When the first reflective part 21 is processed using an integral forming process, processes such as molding, forging, or additive manufacturing can be used. When the first reflective part 21 is obtained by first split forming and then assembling and fixing, the first reinforcing reflective part 211, the first fused reflective part 212, and the polarized reflective part 213 can be fixed by welding, riveting, or hinged connections.

[0076] In some embodiments, the energy intensities of the near-compensation beam 371, the far-compensation beam 372, and the enhanced compensating beam 373 increase sequentially, wherein the spatial region occupied by the far-compensation beam 372 is located between the spatial regions occupied by the near-compensation beam 371 and the spatial regions occupied by the enhanced compensating beam 373, such as... Figure 4 As shown. In the final light spot, the third bright area of ​​the road surface illuminated by the near-complementary beam 371 and the first bright area of ​​the road surface illuminated by the enhanced supplementary beam 373 are located on both sides of the second bright area of ​​the road surface illuminated by the far-complementary beam 372.

[0077] In some embodiments, along the direction from the lamp body 11 to the light outlet 252, the second reflector 22 includes a second fusion reflector 221 and a second enhancement reflector 222 arranged sequentially, both located on the light-emitting side of the lamp body 11. The second fusion reflector 221 is used to reflect part of the light from the lamp body 11. The light reflected from the light outlet 252 by the second fusion reflector 221 can be combined with part of the light directly emitted from the light outlet 252 by the lamp body 11 to form a far-compensation beam 372. The second enhancement reflector 222 is used to reflect part of the light from the lamp body 11. The light reflected from the light outlet 252 by the second enhancement reflector 222 can be combined with part of the light directly emitted from the light outlet 252 by the lamp body 11 to form a enhancement beam 373.

[0078] The second fusion reflector 221 is provided so that it reflects part of the light from the lamp body 11 to participate in the formation of the far-compensation beam 372, which can compensate for the energy of the light reflected by the first fusion reflector 212 and help to improve the energy intensity of the far-compensation beam 372; the second reinforcement reflector 222 is provided so that it reflects part of the light from the lamp body 11 to participate in the formation of the reinforcement beam 373, which can compensate for the energy of the light reflected by the first reinforcement reflector 211 and help to improve the energy intensity of the reinforcement beam 373.

[0079] As can be seen, a portion of the light from the lamp body 11 can be blocked and reflected by the second reflector, then the projection direction is changed and it participates in forming the far beam 372 and the enhanced beam 373, thus projecting to a more distant position without projecting onto the license plate 310. Therefore, the light energy of the second reflector 22 used to illuminate the license plate 310 is controlled at a relatively low level, preventing the license plate 310 from being overexposed.

[0080] Specifically, the second fusion reflector 221 has a second fusion reflective inner wall disposed relatively close to the optical axis 111 and participating in the formation of the inner wall of the beam cavity 253, and the second enhanced reflector 222 has a second enhanced reflective inner wall disposed relatively close to the optical axis 111 and participating in the formation of the inner wall of the beam cavity 253. Please refer to Figure 5 The distance between the second fused reflective inner wall and the optical axis 111 increases in the direction of the lamp body 11 pointing to the light outlet 252, while the second enhanced reflective inner wall is inclined relative to the second fused reflective inner wall in the direction close to the optical axis 111. Figure 5 In the embodiment shown, the distance between the second enhanced reflective inner wall and the optical axis 111 remains basically unchanged. If the traffic supplement light 100 is cut along the extension direction of the optical axis 111, the second enhanced reflective inner wall basically maintains a straight shape and the curvature is less than that of the second fused reflective inner wall.

[0081] Please see Figures 3-4To facilitate the demonstration of the reflection path of the light emitted by the lamp body 11 within the beam assembly 20, five representative light clusters are selected for demonstration. When analyzing the propagation path of these light clusters, the refraction of the light through the lens 114 and the lens support 115 is ignored.

[0082] First light cluster 31 Figure 3 As shown, part of the light emitted by the light source 112 is first reflected by the collimating reflector 113 to obtain the first incident light 311. The first incident light 311 is incident on the first reinforcing reflective inner wall of the first reinforcing reflective part 211 to obtain the first reflected light 312. Finally, the first reflected light 312 is emitted out of the light outlet 252 to form a reinforcing supplementary beam.

[0083] Second light cluster 32, as shown Figure 3 As shown, part of the light emitted by the light source 112 is first reflected by the collimating reflector 113 to obtain the second incident light 321. The second incident light 321 is incident on the first fusion reflector inner wall of the first fusion reflector 212 to obtain the second reflected light 322. Finally, the second reflected light 322 is emitted out of the light outlet 252 to form a far-compensation beam.

[0084] Third light cluster 33 Figure 3 As shown, a portion of the light emitted by the light source 112 is incident as the third incident light 331 onto the polarization reflection inner wall of the polarization reflection section 213, and then forms the third reflected light 332 and exits through the light outlet 252 to form a near-complementary beam.

[0085] In addition, some of the light emitted by the lamp body 11 is not reflected by the collimating reflector 113 or the inner wall of the hollow lamp cover, but is directly emitted from the light outlet 252. This part of the light forms a fourth light cluster 34, which is used to form a near-compensation beam and an enhanced compensating beam.

[0086] In addition, a portion of the light is reflected by the second reflector 22 during propagation, forming the fifth light cluster 35 and the sixth light cluster 36. The fifth light cluster 35... Figure 3 As shown, part of the light emitted by the light source 112 is first reflected by the collimating reflector 113 to obtain the fifth incident light 351. The fifth incident light 351 is incident on the second reflector 22 to obtain the fifth reflected light 352. The fifth reflected light 352 is emitted out of the light outlet 252 to form a far-compensation beam.

[0087] Sixth light cluster 36 Figure 3 As shown, part of the light emitted by the light source 112 is first reflected by the collimating reflector 113 to obtain the sixth incident light 361. The sixth incident light 361 is incident on the second reflector 22 to obtain the sixth reflected light 362. The sixth reflected light 362 is finally emitted out of the light outlet 252 to form an enhanced supplementary beam.

[0088] Examine the first reflected light 312, the second reflected light 322, and the third reflected light 332. (See reference...) Figure 3 Due to the shape of the inner wall of the first reflector 21 and the fact that the reflection points of the first light cluster 31, the second light cluster 32, and the third light cluster 33 gradually move away from the lamp body 11 and closer to the light outlet 252, the bright area of ​​the road surface 200 illuminated by the first reflected light 312 is furthest from the traffic supplementary light 100, the bright area of ​​the road surface 200 illuminated by the third reflected light 332 is closest to the traffic supplementary light 100, and the distance between the bright area of ​​the road surface 200 illuminated by the second reflected light 322 and the traffic supplementary light 100 is in the middle. At least a portion of both the second reflected light 322 and the first reflected light 312 merges with the fourth light cluster 34.

[0089] At least a portion of the light from the fifth reflected light 352 and the sixth reflected light 362 also merged with the fourth light cluster 34. Compared to the distance between the position of the first reflected light 312 illuminating the road surface 200 and the traffic supplement light 100, the positions of the fourth light cluster 34, the fifth reflected light 352, and the sixth reflected light 362 illuminating the road surface 200 are farther from the traffic supplement light 100, and the distance from the bright area of ​​the fourth light cluster 34, the fifth reflected light 352, and the sixth reflected light 362 projected onto the road surface to the traffic supplement light 100 increases sequentially.

[0090] See Figure 4 The near-beam 371 illuminates the license plate 310, the far-beam 372 illuminates the engine hood and driver's compartment of the vehicle 300, and the enhanced beam 373 illuminates the driver's compartment and sunroof of the vehicle 300. The energy intensity of the near-beam 371, far-beam 372, and enhanced beam 373 increases sequentially. The direction indicated by arrow F in the diagram is the driving direction prescribed by the road. Thanks to a portion of the second reflected light 322 and most of the first reflected light 312 being offset from the third reflected light 332, and since the illumination of the license plate 310 is mainly provided by the third reflected light 332, the illuminance received by the license plate 310 decreases, and the license plate 310 is less prone to overexposure. Furthermore, most of the first reflected light 312, and a portion of the second reflected light 322, merge with the fourth light cluster 34, a portion of the fifth reflected light 352, and a portion of the sixth reflected light 362, thus increasing the illuminance received by the driver's compartment and passengers, allowing the road monitoring camera to capture more detailed and clear images of people.

[0091] In some embodiments, at least one of the third reflector 23 and the fourth reflector 24 is movable relative to the first reflector 21 and the second reflector 22, thereby allowing the third reflector 23 and the fourth reflector 24 to move relatively closer or relatively farther apart. This arrangement can change the shape of the beam cavity 253 and the shape of the light outlet 252 according to the actual shape, position, and size of the field of view, ultimately changing the limitation and constraint of the light illumination range by the light outlet 252. For example, when the lane is widened, at least one of the third reflector 23 and the fourth reflector 24 can be moved relatively away from the other, thereby increasing the width of the beam cavity 253 and the size of the light outlet 252. Compared to before the adjustment, the light spot area formed by the traffic supplementary light 100 is larger after the adjustment; or, for example, when it is necessary to switch the position of the lane illuminated by the traffic supplementary light 100, the third reflector 23 and the fourth reflector 24 can be adjusted simultaneously while keeping the opening size of the light outlet 252 constant, ultimately achieving the displacement of the road surface light spot along the width direction of the lane.

[0092] In some embodiments, the edge of the splicing interface 1133 of the collimating reflector 113 is circular, and the edge of the lens bracket 115 is circular. In order to accommodate the edge of the splicing interface 1133 and the edge of the lens bracket 115, so that the hollow lampshade can be better fixedly connected to the edge of the splicing interface 1133 and the lens bracket 115, the shape of the light inlet 251 is circular, and the size is the same as the edge of the splicing interface 1133.

[0093] In some embodiments, to ensure that the shape of the illuminated area on the road surface 200 illuminated by the traffic auxiliary light 100 conforms to the shape of the field of view, the light outlet 252 is quadrilateral in shape. Thus, the light spot formed on the road surface 200 is quadrilateral, adapting to the similarly quadrilateral shape of the field of view. This improves light utilization, ensuring that all light emitted through the light outlet 252 is used to illuminate the designated target area on the road surface 200, without illuminating areas outside the target area, thus avoiding light waste.

[0094] Since the light from the traffic supplement light 100 is projected onto the road surface 200 at an angle relatively inclined to the horizontal direction, in order to obtain a rectangular light spot on the road surface 200 to adapt to the rectangular field of view, the shape of the edge of the light outlet 252 is trapezoidal. The end of the first reflector 21 away from the light-emitting component 10 and the collimating reflector 113, that is, the end of the first reflector 21 that participates in forming the edge of the light outlet 252, is used to form the shorter of the two parallel sides in the trapezoid. The end of the second reflector 22 away from the light-emitting component 10, that is, the end of the second reflector 22 that participates in forming the edge of the light outlet 252, is used to form the longer of the two parallel sides in the trapezoid. In actual installation and use, the first reflector 21 is located on the side of the traffic supplement light 100 that is relatively far from the road surface 200, and the second reflector 22 is located on the side of the traffic supplement light 100 that is relatively close to the road surface 200. The two are vertically opposite each other. If the traffic supplement light 100 is observed from the perspective of a person standing on the road surface 200, the position and orientation of the light outlet 252 show a trend of being smaller at the top and larger at the bottom; that is, in a trapezoid, the shorter of the two parallel sides is located above the longer one. Figure 1 As shown.

[0095] Furthermore, the beam-beaming assembly 20 also includes a shaping ring 26, which is a hollow closed-loop structure and is fixedly connected to the outer walls of the first reflector 21, the second reflector 22, the third reflector 23, and the fourth reflector 24. That is, the shaping ring 26 can be fitted onto the outer wall of the hollow lampshade, thereby providing rigid support and strength compensation for the hollow lampshade. As mentioned earlier, the light inlet 251 of the hollow lampshade can be circular, and the light outlet 252 is preferably trapezoidal or other quadrilateral. Therefore, the ends of each reflector in the hollow lampshade need to be curved, which also means that the edges formed between the reflectors tend to disappear along the direction from the light outlet 252 towards the lamp body 11, and finally the hollow lampshade converges at the edge of the circular light inlet 251. The shaping ring 26 can significantly improve the problem of decreased rigidity of the hollow lampshade along the direction from the light outlet 252 towards the lamp body 11.

[0096] Optionally, the shaping ring 26 can be quadrilateral, with its four sides corresponding to the fixing of the first fusion reflector, the polarizing reflector, the third reflector, and the fourth reflector, respectively. Of course, the shaping ring 26 can also be octagonal, in which case the extra four sides can be used to fix the edges between the various reflectors.

[0097] Optionally, the first reflector 21 may have multiple rising-falling undulating segments, see again. Figure 5 , Figure 5In the illustrated embodiment, the first reflector 21 has two rising-falling undulating sections. In the two rising-falling undulating sections, the one relatively closer to the light-emitting component 10 and the collimating reflector 113 includes a first fusion reflector 212 and a polarizing reflector 213, while the one relatively closer to the light outlet 252 is disposed opposite to the second fusion reflector 221 and the second enhanced reflector 222 of the second reflector 22, including a first enhanced reflector 211, a first fusion reflector 212 and a polarizing reflector 213 connected sequentially along the direction from the lamp body 11 to the light outlet 252.

[0098] The two rising-falling undulating sections serve essentially the same purpose. The first fusion reflector 212 reflects light, and at least a portion of the resulting light merges with the portion of light emitted directly from the lamp body 11 through the light outlet 252. The polarizing reflector 213 reflects light, and the resulting light deviates and disperses from the light reflected by the first fusion reflector 212. It is understood that in other embodiments, the number of rising-falling undulating sections can be three or more.

[0099] The present invention also provides a camera device (not shown), including a camera and the traffic supplement light 100 provided by the present invention, the traffic supplement light 100 being used to provide supplementary lighting for the target captured by the camera. In some embodiments, the camera and the traffic supplement light 100 are integrated and installed high above the highway, suspended above the road surface.

[0100] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0101] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
