[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0032] like Figures 1 to 4 As shown, a solar street lamp lighting angle adjustment mechanism of the present invention comprises a light box 1, a lighting unit 2, a reflective structure 3 and a secondary reflector 4, wherein the lighting unit 2, the reflective structure 3 and the secondary reflector 4 are all installed in the light box 1, the lighting unit 2 is used to emit light, the reflective structure 3 is used to adjust the light coverage range in the driving direction of road vehicles, and the secondary reflector 4 is used to adjust the light coverage range of different lanes on the road;

[0033] The reflective structure 3 is composed of a light blocking plate 5 and a light diffuser 6 distributed front and back, and a plurality of adjustment frame structures are arranged on the light blocking plate 5 and the light diffuser 6, and the adjustment frame structures are used to adjust the inclination angle of the light blocking plate 5 or the light diffuser 6;

[0034] Among them, 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 diffuser 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 irradiates light outward in an oblique triangle.

[0035] In the above embodiment, the light box 1 is used to provide an installation position for the lighting unit 2, the reflective structure 3 and the secondary reflector 4 therein, and the opening of the light box 1 faces downward. A light-transmitting plate is installed on the opening of the light box 1 to protect the lighting unit 2, the reflective structure 3 and the secondary reflector 4. The lighting unit 2 is used to emit light, and the reflective structure 3 and the secondary reflector 4 are used to adjust the coverage area and direction of the light irradiated on the road. Among them, the light-blocking plate 5 and the diffuser 6 on the reflective structure 3 will adjust the light coverage range and coverage mode along the driving direction of the road vehicle. When the secondary reflector 4 moves in the lighting unit 2, the secondary reflector 4 can adjust the light coverage range along the width direction of the road.

[0036] Specifically, both the light baffle 5 and the light diffuser 6 can have a reflective effect. The light baffle 5 is located on the side of the lamp box 1 where road vehicles are coming, and the light diffuser 6 is located on the side of the lamp box 1 where road vehicles are leaving. The light baffle 5 tends to be vertical, and the light diffuser 6 is inclined. When the light emitted by the lighting unit 2 is irradiated on the light baffle 5 and the light diffuser 6, the light baffle 5 and the light diffuser 6 reflect and diffuse the light. Since the light baffle 5 tends to be vertical, the light baffle 5 can block the light emitted by the lighting unit 2 and the light reflected by the light diffuser 6. In this way, the light irradiated from the lighting unit 2 to the direction of the driver of the vehicle will be reduced, thereby avoiding the light from affecting the driver's normal driving work. At this time, the light irradiated by the lamp box 1 is diffused in a triangular shape, and one hypotenuse of the triangle is shorter, and the other hypotenuse is longer. At the same time, since the adjustment frame structure can adjust the inclination angle of the light baffle 5 and the light diffuser 6, the direction and range of light irradiation can be effectively adjusted.

[0037] It should be pointed out that due to the special form of light emitted by the light box 1, there will be no blind spot between two adjacent light boxes 1 on the road, so that there will be no alternation of light and dark on the road, thus avoiding visual fatigue of the driver.

[0038] By adjusting the angles of the light blocking plate 5 and the light diffusion plate 6, the lighting angle and coverage range can be adjusted according to actual conditions, which allows the street lamp to dynamically adjust the lighting mode according to actual needs, thereby improving lighting efficiency and reducing unnecessary energy consumption. In addition, by utilizing the oblique triangle lighting method formed by the light blocking plate 5 and the light diffusion plate 6, the direction and intensity of the light can be effectively controlled to avoid direct light to the driver's eyes, reduce safety hazards caused by glare, and improve road traffic safety. Since the light can be diffused into a specific shape through adjustment, the light between adjacent street lamps can be seamlessly connected, eliminating the lighting blind spots that may be caused by traditional street lamps, ensuring uniform lighting of the road surface, and helping to relieve the driver's visual fatigue. In summary, this technical solution, through clever design, not only solves the limitations of traditional solar street lamps, but also lays the foundation for the further development of future intelligent lighting systems.

[0039] In some embodiments of the present invention, Figure 4 As shown, 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 diffusion plate 6 is in the shape of an outwardly convex arc.

[0040] In the above embodiment, the angle between the main board 7 and the folded edge 8 is an obtuse angle, and the opening direction of the obtuse angle is inclined toward the diffuser plate 6, so that the folded edge 8 can be used to better achieve the light blocking effect. Since the shape of the diffuser plate 6 is arc-shaped, it can diffuse the light outward over a large area when reflecting light, thereby increasing the lighting range and avoiding the glare caused by concentrated reflection.

[0041] In some embodiments of the present invention, Figure 5 As shown, the diffuser plate 6 is composed of a reflective substrate 9 and a plurality of reflective gratings 10 installed in the reflective substrate 9. Both the reflective substrate 9 and the reflective gratings 10 are arc-shaped. The plurality of reflective gratings 10 are stacked together, and a reflective gap is left between two adjacent reflective gratings 10.

[0042] In the above embodiment, the reflective substrate 9 is mainly used to support the multiple reflective gratings 10, and when the light passes through the multiple reflective gratings 10, the reflective substrate 9 can block and reflect the light, so as to ensure that the light is irradiated toward the road surface. Since there are holes on the reflective gratings 10 and the reflective gratings 10 are arc-shaped, part of the light can be diffused and reflected through the reflective gratings 10, and the remaining light passes through the surface reflective gratings 10 to irradiate the inner reflective gratings 10. Since there are reflective gaps between two adjacent reflective gratings 10, the inner reflective gratings 10 will divert the light again. In this way, through the joint action of multiple reflective gratings 10, the light in a single direction can be effectively weakened, thereby improving the light diffusion effect, and this structural method can reduce the glare directly seen by the eyes, thereby improving visual comfort. The diffusion of light through multiple layers of reflective gratings 10 can be more uniform on the ground, avoiding excessively bright or dark areas, and ensuring that the entire illuminated space has good lighting quality.

[0043] In some embodiments of the present invention, Figure 4 As shown, the adjustment frame structure includes a long arm 11 located on the upper side and a short arm 12 located on the lower side, one end of the long arm 11 is rotatably connected to the inner wall of the light box 1, and the other end of the long arm 11 is rotatably connected to the light blocking plate 5 or the diffuser 6, one end of the short arm 12 is rotatably connected to the inner wall of the light box 1, and the other end of the short arm 12 is rotatably connected to the light blocking plate 5 or the diffuser 6. When the long arm 11 rotates on the light box 1, the long arm 11 will pull the light blocking plate 5 or the diffuser 6 to move, and the short arm 12 provides support for the light blocking plate 5 or the diffuser 6.

[0044] In the above embodiment, by utilizing the different lengths of the long arm 11 and the short arm 12, when the long arm 11 rotates in the light box 1, the light baffle 5 or the light diffuser 6 can be caused to roll, that is, the light baffle 5 or the light diffuser 6 can be displaced in both the horizontal and vertical directions, and the orientations of the light baffle 5 and the light diffuser 6 can be changed synchronously, thereby realizing multi-form adjustment of the light baffle 5 and the light diffuser 6.

[0045] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a bow-shaped frame 13 is provided on the top of the light box 1, and both ends of the bow-shaped frame 13 slide downward and are inserted into the light box 1. Both ends of the bow-shaped frame 13 are rotatably provided with connecting rods 14, and the two connecting rods 14 are rotatably connected to a long arm 11 on the light-blocking plate 5 and the light-diffusing plate 6 respectively;

[0046] A side platform 15 is fixed on the top of the light box 1 , and a first locking bolt 16 is screwed onto the side platform 15 . The first locking bolt 16 squeezes and locks the bow frame 13 .

[0047] In the above embodiment, when the position of the light baffle plate 5 and the diffuser plate 6 needs to be adjusted, the worker can directly push the bow frame 13 to move, and the bow frame 13 will drive a long arm 11 on the light baffle plate 5 or the diffuser plate 6 to rotate through two connecting rods 14, thereby synchronously adjusting the light baffle plate 5 and the diffuser plate 6, and the side platform 15 and the first locking bolt 16 are mainly used to lock the position of the bow frame 13.

[0048] In actual use, if the structure of the side platform 15 and the first locking bolt 16 is adopted, the positions of the light baffle 5 and the light diffuser 6 can be adjusted before the street lamp is installed. Of course, the movement of the bow frame 13 can also be adjusted by conventional structures such as motors, threaded rods, and push rods. In this way, even if the street lamp is assembled, workers can adjust the light baffle 5 and the light diffuser 6 by remote control.

[0049] In some embodiments of the present invention, Figure 6 As shown, the auxiliary reflector 4 is provided with a rotating column 17, which is rotatably installed in the light box 1, and the auxiliary reflector 4 slides through the rotating column 17 along the radial direction of the rotating column 17, and both ends of the rotating column 17 are slidably sleeved with a collar 18, and the collar 18 is in friction contact with the inner wall of the light box 1, and the collar 18 and the auxiliary reflector 4 are connected by a push-pull arm 19, and the two ends of the push-pull arm 19 are rotatably connected to the auxiliary reflector 4 and the collar 18, respectively, and the auxiliary reflector 4 and the rotating column 17 are connected by a spring piece 20;

[0050] In the natural state, the auxiliary reflector 4 pushes the ring 18 to squeeze the inner wall of the light box 1 through the push-pull arm 19 .

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

[0052] Since the auxiliary reflector 4 will exert a pressing effect on the collar 18 with the help of the push-pull arm 19, the collar 18 will fit tightly against the inner wall of the light box 1. The friction between them can limit the rotation of the rotating column 17, thereby locking the direction of the auxiliary reflector 4. At this time, the elastic thrust generated by the spring piece 20 on the auxiliary reflector 4 will keep the locking state stable. When it is necessary to adjust the angle of the auxiliary reflector 4, the worker only needs to push the auxiliary reflector 4 upward so that the auxiliary reflector 4 can pull the collar 18 to separate from the inner wall of the light box 1 through the push-pull arm 19, thereby unlocking the rotating column 17 and then rotating the auxiliary reflector 4. At this time, the spring piece 20 is elastically deformed. When the adjustment of the auxiliary reflector 4 is completed, the auxiliary reflector 4 is reset on the rotating column 17, and the collar 18 fits against the inner wall of the light box 1 again.

[0053] In actual use, a motor may also be installed on the light box 1 to provide power for the rotation of the auxiliary reflector 4 .

[0054] In some embodiments of the present invention, Figure 7 As shown, the lighting unit 2 is composed of a plurality of light strips 21 arranged horizontally, the arrangement direction of the plurality of light strips 21 is perpendicular to the length direction of the light strips 21, and each light strip 21 is provided with a support column 22, which is rotatably mounted on the inner wall of the light box 1;

[0055] The light box 1 is provided with an adjustment structure for providing power for the support column 22 to rotate.

[0056] In the above embodiment, since the distance between the street lamp and the edge of the road exists in various forms when the street lamp is actually installed, if the lighting unit 2 is made to irradiate directly downward, the light is likely to be irradiated to the roadside flower beds or other areas, but cannot be irradiated to the road surface. Therefore, it is necessary to use an adjustment structure to adjust the irradiation direction of the light strip 21 in the road width direction to facilitate the full focusing of the light onto the road. The support column 22 mainly provides support for the light strip 21. The combination of multiple light strips 21 can ensure that the overall movement of the multiple light strips 21 occupies a smaller space when adjusting the direction.

[0057] In some embodiments of the present invention, Figures 2 to 3 As shown, the adjustment structure includes an arc platform 23 installed on each supporting column 22, and a worm gear is arranged on the outer wall of the arc platform 23. A worm 24 is rotatably arranged in the light box 1, and the worm 24 is meshed with the worm gears on multiple arc platforms 23. The end of the worm 24 extends beyond the light box 1, and a handle 25 is arranged at the end of the worm 24. A 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 light box 1.

[0058] In the above embodiment, by rotating the worm gear 24, multiple arc stages 23 can be used to synchronously rotate multiple support columns 22, thereby realizing synchronous adjustment of multiple light strips 21. The handle 25 can be convenient for workers to operate, and the second locking bolt 26 can lock the position of the handle 25 on the light box 1. That is, when the second locking bolt 26 is tightened, the end of the second locking bolt 26 is in squeeze and friction contact with the outer wall of the light box 1, and the handle 25 cannot be rotated at will.

[0059] In actual use, a motor may be added to the light box 1 to provide power for the rotation of the worm 24, so that remote control operation can be conveniently performed through structures such as a controller.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
