Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a street light that allows for convenient adjustment of the lighting area. Background Technology

[0002] Streetlights, as an important component of urban infrastructure, are widely used in public places such as roads, squares, and parking lots to provide necessary lighting for pedestrians and vehicles. Traditional streetlights are usually installed in a fixed manner, and their lighting area is determined at the time of installation, making it difficult to adjust according to actual needs. However, in actual use, the lighting needs of different road sections and at different times vary significantly. For example, main roads with high traffic volume require a wider lighting range, while side roads with fewer pedestrians may require more attention to the lighting effect of localized areas; at night, in order to save energy, it may be necessary to reduce the lighting area or reduce the lighting intensity.

[0003] Existing street light adjustment technologies suffer from the following shortcomings: While some street lights can have their lighting direction changed manually by adjusting the angle of the lamps, the process is cumbersome, requiring professionals to use tools for adjustment, and the adjustment precision is limited, making it difficult to meet the needs of refined lighting; another type of street light uses an intelligent control system, which can remotely control the switch and adjust the brightness, but the adjustment of the lighting area still relies on the combined control of multiple fixed lamps, making it unable to flexibly adapt to complex and ever-changing lighting scenarios. In addition, adjusting the lighting area of ​​traditional street lights usually requires interrupting road traffic, causing inconvenience to traffic and pedestrians, and also increasing maintenance costs. As a result, existing street light technologies suffer from poor flexibility, inconvenient operation, and high costs in terms of lighting area adjustment. Utility Model Content

[0004] The purpose of this utility model is to provide a street light that facilitates the adjustment of the lighting area. By pressing the flexible mounting component downwards, the flexible pressing component extends outwards along the bottom contour of the pressing component, thereby adjusting the orientation of the lamp panel structure and facilitating the change of the illumination area of ​​the lamp panel structure. At the same time, the adjustment component can be used to independently adjust the four areas on the pressing component, and can also independently adjust the lighting area in a certain direction from different directions, increasing the flexibility of lighting area adjustment and solving the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-6 The street light shown is designed for easy adjustment of the lighting area, and includes:

[0026] Mounting bracket 1 installed inside the lamp holder cover;

[0027] The bottom of the mounting base 1 is equipped with a flexible mounting component 2 with elasticity. Multiple sets of lamp panel structures 3 are installed radially from the center outward from the bottom of the flexible mounting component 2. The inner cavity of the mounting base 1 is movably equipped with a combined extrusion component 4. The extrusion component 4 applies pressure to the flexible mounting component 2 from above to change its shape. The mounting base 1 is also equipped with an adjustment component 5 for adjusting the angle of the extrusion component 4.

[0028] An electric actuator 6 is fixed to the top of the mounting base 1. The piston rod of the electric actuator 6 passes through the inner cavity of the mounting base 1 and is connected to the extruder 4.

[0029] By utilizing the elasticity and flexibility of the flexible mounting component 2, the extrusion component 4 applies pressure to the flexible mounting component 2, causing it to change the orientation of the lamp panel structure 3 along the shape of the extrusion component 4. At the same time, the traditional integral lamp panel is disassembled into multiple groups so that the lamp panel structure 3 can better fit the flexible mounting component 2 after the flexible mounting component 2 deforms. With the adjustment component 5 and the combined extrusion component 4, it is convenient to adjust the orientation of the lamp panel structure 3 independently, thereby changing the lighting area of ​​the street light.

[0030] This device can adjust the lighting area by remotely controlling the electric actuator 6 and the drive motor 52, without the need for on-site manual operation or traffic interruption.

[0031] Among them, such as Figure 3 As shown:

[0032] The extrusion component 4 includes a support frame 41, with movable blocks 42 hinged to the inner side of the support frame 41. The piston rod of the electric push rod 6 is fixedly connected to the top center of the support frame 41. The extrusion component 4 consists of the support frame 41 and four sets of movable blocks 42 hinged to the inner side. It can drive the support frame 41 to lift and lower as a whole through the electric push rod 6, so as to apply uniform pressure to the flexible installation component 2 and make the lamp panel structure 3 expand evenly in all directions. It can also independently adjust the angle of a single movable block 42 through the adjustment component 5 to achieve fine adjustment of the orientation of the lamp panel structure 3 in different areas.

[0033] Furthermore, such as Figure 3 As shown:

[0034] The adjustment assembly 5 includes a support base 51 fixed at the top center of the mounting base 1. A drive motor 52 is fixed around the top of the mounting base 1. A lead screw 53 is fixed to the output shaft of the drive motor 52. The end of the lead screw 53 away from the drive motor 52 is rotatably connected to the support base 51 through a bearing. A connecting seat 54 is threaded to the outer side of the lead screw 53. The connecting seat 54 fits against the top of the mounting base 1. A connecting rod 55 is hinged to the bottom of the connecting seat 54. The other end of the connecting rod 55 passes through the inner cavity of the mounting base 1 and is hinged to the top of the movable block 42. The drive motor 52 drives the lead screw 53 to rotate, and then the lead screw 53 is used to translate the connecting seat 54 to adjust the position of one end of the connecting rod 55. This allows for the adjustment of the deflection of the movable block 42 using the connecting rod 55, and the adjustment of the angle of the movable block 42 in different positions, for adjusting the lighting area of ​​the lamp panel structure 3.

[0035] Preferred, such as Figure 1 and Figure 4 As shown:

[0036] An annular mounting plate 7 is provided below the mounting base 1. The flexible mounting component 2 is located between the mounting base 1 and the annular mounting plate 7. The bottom of the annular mounting plate 7 is provided with a mounting screw 8, which passes through the annular mounting plate 7 and is threadedly connected to the mounting base 1. The cooperation between the annular mounting plate 7 and the mounting screw 8 facilitates the installation of the flexible mounting plate and prevents the flexible mounting component 2 from separating from the mounting base 1 after the flexible mounting plate is pressed by the extrusion component 4.

[0037] It is worth noting that, such as Figure 4 As shown:

[0038] The bottom outer ring of the flexible mounting component 2 is provided with multiple sets of limiting rings 9, and the top of the annular mounting plate 7 is provided with corresponding grooves 10. The cooperation between the limiting rings 9 and the grooves 10 facilitates the increase of friction between the flexible mounting component 2 and the annular mounting plate 7, thereby ensuring the stability of the installation of the flexible mounting component 2.

[0039] In a further preferred embodiment, such as Figure 5 As shown:

[0040] The flexible mounting component 2 has multiple sets of through holes 11. The top of the lamp panel structure 3 is provided with a retainer 12, which is engaged in the through holes 11. With the cooperation of the retainer 12, the lamp panel structure 3 and the flexible mounting component 2 can be easily connected. When the flexible mounting component 2 is squeezed and expanded, the through holes 11 expand along with it. However, the size of the retainer 12 can ensure the stability between the lamp panel structure 3 and the flexible mounting component 2.

[0041] In practical use, the lamp panel structure 3 is engaged with the through hole 11 on the flexible mounting piece 2 using the bracket 12, connecting the lamp panel structure 3 and the flexible mounting piece 2. Then, the flexible mounting piece 2 is placed between the annular mounting plate 7 and the mounting base 1, and fixed using the mounting screws 8. The mounting base 1 is then installed inside the streetlight housing, and the circuit is connected, connecting the device to the streetlight controller. Under normal circumstances, the flexible mounting piece 2 is flat without external pressure, and all lamp panel structures 3 are on the same plane. After being powered on, the lamp panel structure 3 can illuminate a specific area downwards. When the lighting area needs adjustment, the controller controls the drive motor 52 to rotate, which in turn drives the lead screw 53 to rotate. The lead screw 53 then drives the connecting base 54 to move. The connecting rod 55 is moved by the connecting seat 54. The movement of the connecting rod 55 supports the movable block 42 below, changing the angle between the movable block 42 and the support frame 41. In conjunction with the electric push rod 6, the support frame 41 is moved up and down, making it convenient to apply pressure to the flexible mounting part 2 using the movable block 42. According to the position of the movable block 42, the lamp panel structure 3 at the corresponding position is squeezed, and then the flexible mounting part 2 deforms. The lamp panel structure 3 is attached to the outside of the movable block 42, so that the lamp panel structure 3 is on the curved surface, and the angle changes accordingly, thereby changing the lighting angle and area of ​​the lamp panel structure 3. Since the four sets of drive motors 52 can operate independently, it is convenient to adjust the movable block 42 in a certain position independently, or to adjust the entire movable block 42 simultaneously, reflecting the flexibility of street light lighting area adjustment.

[0042] Meanwhile, the circuit connection of the lamp board structure 3 is designed according to the street lighting requirements and is not within the scope of protection of this patent.

[0043] The flexible mounting component 2 is made of nitrile rubber, which has high elasticity and flexibility, and can adapt to the shape adjustment during the installation of street light panels to a certain extent; it has good oil resistance, water resistance and chemical corrosion resistance, making it suitable for use in harsh outdoor environments; it has good anti-aging properties, and can maintain its elasticity and flexibility for a long time, extending the service life of the street light panels.

[0044] To adapt to the deformation requirements of different areas, the flexible mounting component 2 can achieve differentiated support through localized hardness adjustment. Hardness is typically controlled by changing the acrylonitrile content; higher acrylonitrile content results in greater hardness. For sheet-like nitrile rubber, to achieve different localized hardness, a method can be used to locally coat the sheet material with a solution containing different additives, followed by drying and curing. For example, coating with a solution containing plasticizers can reduce the hardness of localized areas; coating with a solution containing reinforcing agents can increase the localized hardness. Furthermore, different degrees of localized vulcanization treatment can also lead to differences in hardness.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
