Description
Technical Field
[0001] The utility model relates to the technical field of LED street lamps, in particular to a semiconductor solar street lamp with adjustable light. Background Art
[0002] Solar street lights are a type of lighting tool that uses solar power to provide electrical energy for lighting. They generally use semiconductor LED lighting modules, DC power supply, and photosensitivity control. Traditional public electric street lights have gradually been replaced by them because of their good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economy and practicality, no need to lay cables, no AC power supply, and no electricity bills.
[0003] In the existing solar street lights, the solar panel is generally set at different positions of the lamp post separately from the main body of the lamp. The solar street light with the lamp body and the solar panel as two parts occupies more space, so the wind resistance will be relatively large when it is set at a high place, which poses certain safety hazards. Therefore, people have designed some solar street lights that combine solar panels with lamps into one, such as the integrated solar LED street light disclosed in publication number CN216556914U. The battery box of the street light is set at the bottom of the lamp, and the space occupied is relatively large compared to the lamp. The wind resistance will be relatively large when it is set at a high place. If it is not repaired for a long time, the solar street light is prone to damage in extreme weather.
[0004] In addition, in the existing solar street lights, when adjusting the illumination area, the illumination area can be adjusted by changing the swing angle of the light source. However, the swing angle adjustment of the light source requires loosening the fixing parts of the light source to adjust the swing angle of the light source, or removing the light source part from the lamp and reinstalling it in a new position to adjust the illumination angle. It is difficult for workers to perform this operation at high altitudes, and it takes a long time. The adjustment efficiency of the illumination angle of the solar street light is not high.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] See also Figure 1-6 The utility model provides a technical solution: a semiconductor solar street light with adjustable light, comprising a lamp pole 1 and a support rod 2 fixed on the side of the lamp pole 1, the support rod 2 and the interior of the lamp pole 1 are both hollow, a solar power supply panel 3 is screwed fixed to the end of the lamp pole 1 away from the support rod 2, an LED light board 4 is rotatably connected to the end of the support rod 2 away from the lamp pole 1, the LED light board 4 is electrically connected to the solar power supply panel 3, the support rod 2 comprises an outer rod 5 connected to the LED light board 4 and an inner rod 6 fixedly connected to the lamp pole 1, the outer rod 5 is rotatably connected to the inner rod 6, and a driving member for rotating the LED light board 4 is provided inside the outer rod 5.
[0035] A connecting frame 9 is fixed inside the outer rod 5 , a driving shaft 10 is fixed in the middle of the connecting frame 9 , a servo motor 11 is connected to the driving shaft 10 , and the servo motor 11 is screwed inside the inner rod 6 .
[0036] The servo motor 11 can drive the driving shaft 10 to rotate, thereby driving the connecting frame 9 to rotate. Since the connecting frame 9 and the outer rod 5 are fixedly connected, when the connecting frame 9 rotates, the entire outer rod 5 rotates accordingly.
[0037] The driving member includes a cylinder 12 fixed inside the outer rod 5. The cylinder 12 is placed on the connecting frame 9 facing the LED lamp board 4. A connecting rod 13 is fixed to the output end of the cylinder 12. The connecting rod 13 extends out of the outer rod 5 away from the output end of the cylinder 12. A cross bar 14 is fixed to the end of the extended outer rod 5. A resistance rod 15 is fixed to the end of the cross bar 14 away from the connecting rod 13. The resistance rod 15 slides on the upper end of the LED lamp board 4.
[0038] A connecting ball 7 is fixed at one end of the LED light board 4, and a spherical groove 8 is embedded in the outer rod 5 near the end of the LED light board 4, and the connecting ball 7 is rotatably connected with the spherical groove 8.
[0039] A waist-shaped groove 21 is provided on the outer rod 5 for the connecting rod 13 to slide, and a rubber sealing strip 22 is fixed inside the waist-shaped groove 21. A through groove 23 is provided in the rubber sealing strip 22. When the connecting rod 13 slides, it slides along the through groove 23 in the rubber sealing strip 22, and then the rubber sealing strip 22 keeps wrapping the connecting rod 13, which can prevent rainwater, dust, etc. from entering the inner part of the outer rod 5; a slide groove 16 is provided at the upper end of the LED light panel 4, and the slide groove 16 is for the resistance rod 15 to slide.
[0040] In the above structure, the cylinder 12 can drive the connecting rod 13 to slide along the waist-shaped groove 21 on the outer rod 5, and then the cross rod 14 moves with the connecting rod 13, and its moving direction is the axial direction of the outer rod 5. When the cross rod 14 moves toward the end of the LED light board 4, the resistance rod 15 moves along the slide groove 16 and moves to the front end of the LED light board 4. Since the resistance rod 15 and the cross rod 14 are fixedly connected, as the resistance rod 15 moves, the resistance rod 15 presses down the LED light board 4. At this time, the LED light board 4 drives the connecting ball 7 to rotate downward. When the resistance rod 15 moves back, the LED light board 4 moves upward to its initial position again.
[0041] Furthermore, the above-mentioned moving direction is rotation in the axial direction of the outer rod 5, and under the drive of the above-mentioned servo motor 11, the LED light board 4 rotates with the outer rod 5, that is, rotates in the direction perpendicular to the axis of the outer rod 5, and then the LED light board 4 rotates in four directions to achieve lighting area adjustment in multiple directions.
[0042] Among them, the servo motor 11 is electrically connected to the first control button 17, and the cylinder 12 is electrically connected to the second control button 18. The first control button 17 and the second control button 18 are both placed inside the lamp pole 1. The lamp pole 1 is provided with a placement groove 19 corresponding to the first control button 17 and the second control button 18. The placement groove 19 is hinged with a cover plate 20 on the outside, and the cover plate 20 is screwed to the lamp pole 1 away from the hinge. The first control button 17 and the second control button 18 are integrated inside the lamp pole 1, and are electrically connected to the servo motor 11 and the cylinder 12 respectively. Two first control buttons 17 and two second control buttons 18 are set. The two first control buttons 17 respectively control the forward and reverse rotation of the servo motor 11, and the two second control buttons 18 respectively control the extension and retraction of the cylinder 12. The cover plate 20 is fixed on the outside with a lock, so that the lighting area of the LED light board 4 can only be adjusted when the staff opens the cover plate 20.
[0043] The working principle of the utility model is as follows: the LED light panel 4 is powered by the solar power panel 3, and the servo motor 11 is controlled to work by pressing the first control button 17. The servo motor 11 can drive the LED light pole 1 to rotate and adjust. At the same time, after the cylinder 12 is opened, the cylinder 12 drives the connecting rod 13 and the cross rod 14 to move, driving the resistance rod 15 to move forward and backward. With the movement of the resistance rod 15, the LED light panel 4 can be adjusted to rotate forward and backward, thereby realizing the adjustment of the lighting area of the LED light panel 4 in multiple directions.
