[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0032] like Figures 1 to 4 As shown, a solar street light illumination angle adjustment mechanism of the present invention includes a light box 1, an illumination unit 2, a reflective structure 3, and a secondary reflector 4. The illumination unit 2, the reflective structure 3, and the secondary reflector 4 are all installed inside the light box 1. The illumination unit 2 is used to emit light, the reflective structure 3 is used to adjust the light coverage range in the direction of vehicle travel on the road, and the secondary reflector 4 is used to adjust the light coverage range of different lanes on the road.

[0033] The reflective structure 3 consists of a light-blocking plate 5 and a light-diffusing plate 6 distributed in a front-to-back manner. Both the light-blocking plate 5 and the light-diffusing plate 6 are provided with multiple sets of adjustment frame structures, which are used to adjust the tilt angle of the light-blocking plate 5 or the light-diffusing plate 6.

[0034] The light blocking plate 5 is used to reflect and block the light emitted by the lighting unit 2 to reduce the light coverage range, and the light diffusing plate 6 is used to reflect and diffuse the light emitted by the lighting unit 2 to increase the light coverage range, so that the light box 1 emits light in a slanting triangular shape.

[0035] In the above embodiment, the light box 1 is used to provide mounting positions for the lighting unit 2, the light reflecting structure 3 and the auxiliary light reflecting plate 4 in the light box 1, and the opening of the light box 1 faces downward, and a light-transmitting plate will be mounted on the opening of the light box 1 to protect the lighting unit 2, the light reflecting structure 3 and the auxiliary light reflecting plate 4, the lighting unit 2 is used to emit light, and the light reflecting structure 3 and the auxiliary light reflecting plate 4 are used to adjust the coverage area and direction of the light emitted on the road, wherein the light blocking plate 5 and the light diffusing plate 6 on the light reflecting structure 3 can adjust the light coverage range and coverage mode along the driving direction of the vehicle on the road, and the auxiliary light reflecting plate 4 can adjust the light coverage range along the width direction of the road when the auxiliary light reflecting plate 4 moves in the lighting unit 2.

[0036] Specifically, the light blocking plate 5 and the light diffusing plate 6 can both have a light reflecting effect, the light blocking plate 5 is located on the side of the light box 1 where the vehicle on the road drives in, the light diffusing plate 6 is located on the side of the light box 1 where the vehicle on the road drives out, the light blocking plate 5 tends to be vertical, and the light diffusing plate 6 is inclined, when the light emitted by the lighting unit 2 is incident on the light blocking plate 5 and the light diffusing plate 6, the light blocking plate 5 and the light diffusing plate 6 reflect and diffuse the light, and because the light blocking plate 5 tends to be vertical, the light blocking plate 5 can block the light emitted by the lighting unit 2 and the light reflected by the light diffusing plate 6, so that the light emitted by the lighting unit 2 in the direction of the vehicle driver is reduced, thereby avoiding the influence of the light on the normal driving work of the driver, at this time, the light emitted by the light box 1 is diffused in a triangular shape, and one of the two oblique sides of the triangle is shorter and the other is longer, and because the adjusting frame structure can adjust the inclination angle of the light blocking plate 5 and the light diffusing plate 6, the light emission direction and range can be effectively adjusted.

[0037] It should be noted that because of the special form of the light emitted by the light box 1, there will be no blind area between two adjacent light boxes 1 on the road, so that there will be no light-dark alternating phenomenon on the road, and the driver's visual fatigue is avoided.

[0038] By adjusting the angles of the light blocking plate 5 and the light diffusing plate 6, the illumination angle and coverage can be adjusted according to actual conditions, which allows the street lamp to dynamically adjust the illumination mode according to actual needs, improves the illumination efficiency, reduces unnecessary energy consumption, and uses the inclined triangular illumination mode formed by the light blocking plate 5 and the light diffusing plate 6 to effectively control the direction and intensity of the light, avoid the light directly shining into the driver's eyes, reduce the safety hazards caused by glare, and improve the safety of road traffic; Since the light can be adjusted to form a specific shape of diffusion, the light between adjacent street lamps can be seamlessly connected, eliminating the illumination blind area that may be generated by traditional street lamps, ensuring uniform illumination of the road surface, and helping to alleviate the visual fatigue of the driver; In summary, the technical scheme solves the limitations of traditional solar street lamps and lays a foundation for the further development of future intelligent lighting systems through ingenious design.

[0039] In some embodiments of the present application, as shown in Figure 4 The light blocking plate 5 is composed of a main plate 7 located on the upper side and a folded edge 8 located on the lower side, and the light diffusing plate 6 is in the shape of an outward convex arc.

[0040] In the above embodiment, the included angle between the main plate 7 and the folded edge 8 is an obtuse angle, and the obtuse angle opening direction is inclined towards the light diffusing plate 6, so that the light blocking effect can be better realized by using the folded edge 8. Since the light diffusing plate 6 is in the shape of an arc, it can diffuse the light outward in a large area when reflecting the light, increase the illumination range, and avoid the dazzling phenomenon caused by concentrated reflection.

[0041] In some embodiments of the present application, as shown in Figure 5 The light diffusing plate 6 is composed of a light reflecting substrate 9 and a plurality of light reflecting gratings 10 installed in the light reflecting substrate 9, the light reflecting substrate 9 and the light reflecting grating 10 are both in the shape of an arc, the plurality of light reflecting gratings 10 are stacked together, and there is a light reflecting gap between the adjacent two light reflecting gratings 10.

[0042] In the above embodiment, the light-reflecting base plate 9 is mainly used to support the plurality of light-reflecting grids 10, and when the light passes through the plurality of light-reflecting grids 10, the light-reflecting base plate 9 can block and reflect the light, so as to ensure that the light is irradiated towards the road surface. Since there are holes on the light-reflecting grids 10 and the light-reflecting grids 10 are arc-shaped, part of the light can be diffusely reflected through the light-reflecting grids 10, and the remaining light is irradiated to the light-reflecting grids 10 in the inner layer through the surface light-reflecting grids 10. Since there is a light-reflecting gap between the adjacent two light-reflecting grids 10, the light-reflecting grids 10 in the inner layer can again shunt the light. Through the joint action of the plurality of light-reflecting grids 10, the light in a single direction can be effectively weakened, so as to improve the light diffusion effect. The structure can reduce the glare directly seen by the eyes, so as to improve the visual comfort. The light diffused through the plurality of light-reflecting grids 10 can be more uniform on the ground, avoiding the excessively bright or dark area, and ensuring that the entire illuminated space has good illumination quality.

[0043] In some embodiments of the present application, as shown in Figure 4 The adjusting frame structure comprises a long arm 11 on the upper side and a short arm 12 on the lower side. One end of the long arm 11 is rotationally connected with the inner wall of the lamp box 1, and the other end of the long arm 11 is rotationally connected with the light-blocking plate 5 or the light-diffusing plate 6. One end of the short arm 12 is rotationally connected with the inner wall of the lamp box 1, and the other end of the short arm 12 is rotationally connected with the light-blocking plate 5 or the light-diffusing plate 6. When the long arm 11 rotates in the lamp box 1, the long arm 11 pulls the light-blocking plate 5 or the light-diffusing plate 6 to move, and the short arm 12 supports the light-blocking plate 5 or the light-diffusing plate 6.

[0044] In the above embodiment, by virtue of the different lengths of the long arm 11 and the short arm 12, when the long arm 11 rotates in the lamp box 1, the light-blocking plate 5 or the light-diffusing plate 6 can roll, that is, the light-blocking plate 5 or the light-diffusing plate 6 can displace in the horizontal and vertical directions, and the orientation of the light-blocking plate 5 or the light-diffusing plate 6 can be changed synchronously, thereby realizing the multi-form adjusting work of the light-blocking plate 5 or the light-diffusing plate 6.

[0045] In some embodiments of the present application, as shown in Figure 1 and Figure 4 The top of the lamp box 1 is provided with an arc-shaped frame 13. Both ends of the arc-shaped frame 13 are slidably inserted into the lamp box 1, and both ends of the arc-shaped frame 13 are rotationally provided with connecting rods 14. The two connecting rods 14 are respectively rotationally connected with one long arm 11 on the light-blocking plate 5 or the light-diffusing plate 6.

[0046] The top of the lamp box 1 is fixed with a side table 15, and the first locking bolt 16 is screwed on the side table 15 to extrude and lock the arc-shaped frame 13.

[0047] In the above embodiment, when the light blocking plate 5 and the light diffusing plate 6 need to be adjusted, the worker can directly push the arc-shaped frame 13 to move, and the arc-shaped frame 13 drives one long arm 11 on the light blocking plate 5 or the light diffusing plate 6 to rotate through the two connecting rods 14, so as to synchronously adjust the light blocking plate 5 and the light diffusing plate 6. The side table 15 and the first locking bolt 16 are mainly used for locking the position of the arc-shaped frame 13.

[0048] In actual use, if the structure of the side table 15 and the first locking bolt 16 is adopted, the positions of the light blocking plate 5 and the light diffusing plate 6 can be adjusted before the street lamp is installed. Of course, the movement of the arc-shaped frame 13 can also be completed by adjusting the conventional structure such as a motor, a threaded rod, a push rod, etc. Thus, even if the street lamp is assembled, the worker can also adjust the light blocking plate 5 and the light diffusing plate 6 by means of remote control.

[0049] In some embodiments of the present application, as shown in Figure 6 The auxiliary reflecting plate 4 is provided with a rotating column 17, the rotating column 17 is rotationally installed in the lamp box 1, the auxiliary reflecting plate 4 slides through the rotating column 17 along the radial direction of the rotating column 17, the rotating column 17 is slidably sleeved with a sleeve ring 18 at both ends, the sleeve ring 18 is in frictional contact with the inner wall of the lamp box 1, the sleeve ring 18 and the auxiliary reflecting plate 4 are connected through a push-pull arm 19, and the two ends of the push-pull arm 19 are rotationally connected with the auxiliary reflecting plate 4 and the sleeve ring 18 respectively, and the auxiliary reflecting plate 4 and the rotating column 17 are connected through an elastic sheet 20.

[0050] In the natural state, the auxiliary reflecting plate 4 pushes the sleeve ring 18 to extrude the inner wall of the lamp box 1 through the push-pull arm 19.

[0051] In the above embodiment, the auxiliary reflecting plate 4 can rotate in the lamp box 1 by means of the rotating column 17, so that the reflecting angle of the auxiliary reflecting plate 4 can be adjusted, thereby facilitating the adjustment of the light coverage range in the width direction of the road.

[0052] Since the auxiliary reflecting plate 4 can exert a pressing force on the sleeve ring 18 through the push-pull arm 19, the sleeve ring 18 is tightly attached to the inner wall of the lamp box 1, and the rotation of the rotating column 17 can be limited by the friction therebetween, thereby locking the direction of the auxiliary reflecting plate 4. At this time, the elastic pushing force of the elastic sheet 20 on the auxiliary reflecting plate 4 can keep the locking state stable. When the angle of the auxiliary reflecting plate 4 needs to be adjusted, the worker only needs to push the auxiliary reflecting plate 4 upward, so that the auxiliary reflecting plate 4 pulls the sleeve ring 18 away from the inner wall of the lamp box 1 through the push-pull arm 19, thereby unlocking the rotating column 17. Then, the auxiliary reflecting plate 4 can be rotated. At this time, the elastic sheet 20 is elastically deformed. When the adjustment of the auxiliary reflecting plate 4 is completed, the auxiliary reflecting plate 4 is reset on the rotating column 17, and the sleeve ring 18 is attached to the inner wall of the lamp box 1 again.

[0053] In actual use, a motor can also be installed on the lamp box 1 to provide power for the rotation of the auxiliary reflecting plate 4. In actual use, a motor can also be installed on the lamp box 1 to provide power for the rotation of the auxiliary reflecting plate 4.

[0054] In some embodiments of the present application, as shown in Figure 7 The lighting unit 2 is composed of a plurality of lamp strips 21 arranged horizontally, the arrangement direction of the plurality of lamp strips 21 is perpendicular to the length direction of the lamp strip 21, each lamp strip 21 is provided with a support column 22, and the support column 22 is rotatably installed on the inner wall of the lamp box 1.

[0055] The lamp box 1 is provided with an adjusting structure for providing power for the rotation of the support column 22.

[0056] In the above embodiment, since the distance between the street lamp and the edge of the road is in various forms during actual installation, if the lighting unit 2 directly irradiates downward, the light is easy to irradiate into the roadside flower bed or other areas, and cannot irradiate onto the road surface, so it is necessary to adjust the irradiation direction of the lamp strip 21 in the width direction of the road by using the adjusting structure, so as to facilitate the overall focusing of the light onto the road, and the support column 22 mainly provides support for the lamp strip 21, and the combined arrangement of the plurality of lamp strips 21 can ensure that the overall movement of the plurality of lamp strips 21 occupies a smaller space during adjustment.

[0057] In some embodiments of the present application, as shown in Figures 2 to 3 The adjusting structure includes an arc table 23 installed on each support column 22, the outer wall of the arc table 23 is provided with a worm gear, the lamp box 1 is rotatably provided with a worm 24, the worm 24 is engaged with the worm gears on the plurality of arc tables 23, the end of the worm 24 extends out of the lamp box 1, and the end of the worm 24 is provided with a handle 25, the second locking bolt 26 is screwed on the handle 25, and the end of the second locking bolt 26 is pressed against the outer wall of the lamp box 1.

[0058] In the above embodiment, by rotating the worm 24, the plurality of arc tables 23 can be used to synchronously rotate the plurality of support columns 22, thereby achieving synchronous adjustment of the plurality of lamp strips 21, the handle 25 can be conveniently operated by workers, and the second locking bolt 26 can lock the position of the handle 25 on the lamp box 1, that is, when the second locking bolt 26 is tightened, the end of the second locking bolt 26 is in frictional contact with the outer wall of the lamp box 1, and at this time the handle 25 cannot be arbitrarily rotated.

[0059] In actual use, a motor can also be additionally provided on the lamp box 1 to provide power for the rotation of the worm 24, so that remote control operation can be conveniently achieved by using a controller or the like.

[0060] The above only describes the preferred embodiments of the present application, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
