DETAILED DESCRIPTION

[0023] 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 of the embodiments.

[0024] Reference Figure 1-Figure 6 A smart street lamp with adjustable lighting brightness comprises a lamp pole 1, a mounting plate 2 is fixedly mounted on the upper end of the lamp pole 1, a lamp body 3 is fixedly mounted on the mounting plate 2, a lamp shade 4 is fixedly mounted on the mounting plate 2, and the lamp body 3 is located in the lamp shade 4;

[0025] A winding shaft 5 is installed in the lampshade 4 for horizontal symmetry and rotation. A guide shaft 6 is installed in the lampshade 4 for horizontal symmetry and rotation. A light shielding film 7 is provided in the lampshade 4. Both ends of the light shielding film 7 are respectively fixedly connected to the two winding shafts 5 and are respectively wound on the two winding shafts 5. The light shielding film 7 is in rolling contact with the two guide shafts 6. The light shielding film 7 is located directly below the lamp body 3. A transmission assembly for simultaneously driving the two winding shafts 5 to rotate is provided on the mounting plate 2.

[0026] The light shielding film 7 is divided into three light shielding areas, namely a first light shielding area 701, a second light shielding area 702 and a third light shielding area 703, and the light transmittances of the first light shielding area 701, the second light shielding area 702 and the third light shielding area 703 decrease in sequence;

[0027] The light generated by the lamp body 3 will pass through the shading film 7. The three areas on the shading film 7 have different light transmittances. Therefore, after the light passes through the shading film 7, the intensity will also change differently. In the evening, the light generated by the lamp body 3 can pass through the first shading area 701, at which time the light intensity is the brightest. Near midnight, the light generated by the lamp body 3 can pass through the second shading area 702, at which time the light intensity is moderate. At midnight when the flow of people is the least, the light generated by the lamp body 3 can pass through the third shading area 703, at which time the light intensity is the weakest, so as to adjust the brightness of the street lamp and prevent light pollution caused by the street lamp.

[0028] Both ends of the shading film 7 are respectively wound on the winding shaft 5, and the winding shaft 5 can be driven to rotate by the transmission component, so that the shading film 7 is wound on the winding shaft 5, or released from the winding shaft 5, so as to replace the shading area under the lamp body 3.

[0029] The transmission assembly includes a driving motor 8 fixedly mounted on the mounting plate 2, a driving wheel 9 fixedly sleeved on the output shaft of the driving motor 8, two driven wheels 10 respectively fixedly sleeved on the two winding shafts 5, and a transmission belt 11, the transmission belt 11 is sleeved on the driving wheel 9 and the two driven wheels 10, and a PLC control board is provided in the driving motor 8, and the PLC control board is electrically connected to the driving motor 8;

[0030] The PLC control board is a prior art and is not shown in the figure. It can control the start and stop of the drive motor 8 by time periods. When the drive motor 8 rotates, it drives the driving wheel 9 to rotate through the output shaft, and then drives the two driven wheels 10 to rotate through the transmission belt 11, thereby driving the two winding shafts 5 to rotate at the same time.

[0031] Support rods 12 are symmetrically fixedly installed on the inner walls of both sides of the lampshade 4, and a first scraper rod 13 is fixedly installed on one end of the two support rods 12 on the same side. A second scraper rod 14 is installed on the first scraper rod 13 through an elastic component. The shading film 7 is clamped between the first scraper rod 13 and the second scraper rod 14. The elastic component includes two U-shaped frames 15 respectively fixedly installed at both ends of the first scraper rod 13 and two spring rods 16 respectively fixedly installed on the two U-shaped frames 15. The two spring rods 16 are fixedly connected to the second scraper rod 14;

[0032] Under the action of the elastic force of the spring rod 16, the second scraper rod 14 tends to move toward the first scraper rod 13, thereby tightly clamping the shading film 7 between the first scraper rod 13 and the second scraper rod 14. When the shading film 7 moves, the first scraper rod 13 and the second scraper rod 14 can remove dust on the surface of the shading film 7 to prevent dust from affecting light passing through the shading film 7.

[0033] The lampshade 4 is provided with a plurality of heat dissipation holes, the number of which is no less than five. The heat generated by the lamp body 3 can be dissipated through the heat dissipation holes, thereby achieving a cooling effect.

[0034] In the utility model, when it is necessary to adjust the lighting brightness of the street lamp, the two winding shafts 5 are driven to rotate through the transmission assembly, and then the shading film 7 is driven to move under the lamp body 3 through the two guide shafts 6, so that the light generated by the lamp body 3 can pass through the shading areas with different transmittances on the shading film 7, thereby realizing the adjustment of the lighting brightness of the street lamp and preventing light pollution caused by the street lamp.

[0035] In general, in response to the technical problem that the lighting brightness cannot be adjusted, which leads to excessive lighting brightness and light pollution when the flow of people is small late at night, a technical solution is adopted: the brightness of the street lamp can be adjusted through the cooperation of the winding shaft 5, the guide shaft 6, the transmission assembly and the shading film 7; because the implementation process of the technical solution is: when the brightness of the street lamp needs to be adjusted, the two winding shafts 5 are driven to rotate by the transmission assembly, and then the shading film 7 is driven to move under the lamp body 3 by the two guide shafts 6, so that the light generated by the lamp body 3 can pass through the shading areas with different transmittances on the shading film 7; so this technical problem can definitely be solved, and the technical effect achieved is: the brightness of the street lamp can be adjusted to prevent light pollution caused by the street lamp.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
