Description

Technical Field

[0001] This utility model relates to the field of building lighting technology, and in particular to an adjustable light reflection device for enhancing lighting on low floors. Background Technology

[0002] With the acceleration of urbanization and the increasing density of high-rise buildings, many lower floors, basements, and obstructed interior spaces of buildings cannot receive sufficient natural light. Long-term reliance on artificial lighting not only consumes a large amount of electricity and increases operating costs, but also contradicts the concept of green and low-carbon development, and negatively impacts the physical and mental health of those living in such environments. Therefore, adjustable light reflectors have been invented to enhance the lighting of lower floors. These devices precisely reflect sunlight that would otherwise not reach lower floors and guide it into the interior, increasing indoor lighting and reducing the need for artificial lighting during the day.

[0003] However, most existing adjustable light reflectors have a rigid structure with a fixed shape and curvature on the reflector surface. Once installed, their optical characteristics are permanently fixed and cannot be adjusted according to the sun's position, weather changes, or user needs. This lack of dynamic adjustability results in extremely low annual overall efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable light reflection device for enhancing the lighting of low-rise buildings, which can change the curvature of the reflective surface to adapt to different user needs.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An adjustable light reflector for enhancing daylighting in lower floors includes:

[0007] Support column;

[0008] Multiple unit reflective structures are arranged sequentially around the support column in a circumferential manner. Each unit reflective structure includes a reflector, a first connecting rod, and an angle locking member. Multiple reflectors belonging to different unit reflective structures are sequentially spliced ​​around the support column in an axial manner. One end of the first connecting rod is hinged to the support column, and the other end of the first connecting rod is hinged to the reflector belonging to the same unit reflective structure, so that the included angle between the multiple reflectors belonging to different unit reflective structures can be adjusted. The angle locking member belonging to the same unit reflective structure locks the first connecting rod and the reflector together.

[0009] Furthermore, a central reflector is connected to the upper end of the support column, and the central reflector is disposed within the space formed by the plurality of reflectors.

[0010] Furthermore, the centered reflector is fixed to the support column.

[0011] Furthermore, the angle locking component includes a locking bolt and an anti-detachment end cap. The locking bolt passes through the first connecting rod and the reflector, and is then connected to the anti-detachment end cap.

[0012] Furthermore, the locking bolt is provided with a first threaded section and a smooth section in sequence; the first threaded section is threadedly engaged with the first connecting rod, and the smooth section is used to clearance-fit the first connecting rod so that the reflector can swing relative to the first connecting rod.

[0013] Furthermore, the locking bolt is also provided with a second threaded section, and the first threaded section, the smooth section and the second threaded section are arranged in sequence, with the second threaded section threadedly engaging with the anti-detachment end cap.

[0014] Furthermore, the unit reflective structure also includes a second link, one end of which is hinged to the first link, and the other end of which is hinged to a support seat belonging to the same unit reflective structure. A plurality of the support seats are distributed circumferentially around the outer side of the support column.

[0015] Furthermore, the shapes of the plurality of reflectors and the central reflector are all polygonal.

[0016] Furthermore, the support column has a threaded rod, and the adjustable light reflection device for enhancing the lighting of low floors also includes a mounting base, the mounting base having a threaded hole, and the threaded rod being threadedly connected to the threaded hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The unit reflective structure includes a reflector, a first connecting rod, and an angle locking component. Multiple reflectors belonging to different unit reflective structures are sequentially spliced ​​around the support column along its axis. One end of the first connecting rod is hinged to the support column, and the other end is hinged to a reflector belonging to the same unit reflective structure, allowing the included angle between the multiple reflectors belonging to different unit reflective structures to be adjustable. Thus, by adjusting the included angle, it can flexibly adapt to changes in the solar altitude angle at different seasons and times, achieving precise control of the reflected light path and always directing light to the target area on the lower floors, maximizing the year-round lighting effect.

[0019] 2. The first link and the reflector are locked together by an angle locking component belonging to the same reflective structure. This forms a stable and reliable mechanical connection, ensuring that the reflector can resist external forces and remain in its position after being adjusted to the optimal angle, effectively preventing the reflector from shaking and ensuring that the reflected light spot does not drift.

[0028] See Figures 1-4An adjustable light reflection device for enhancing daylighting in low-rise buildings, according to a preferred embodiment of the present invention, includes a support column 1 and multiple unit reflective structures 2. Each unit reflective structure 2 includes a reflector 21, a first connecting rod 22, and an angle locking member 3. Multiple reflectors 21 belonging to different unit reflective structures 2 are sequentially spliced ​​around the support column 1 along its axial direction. One end of the first connecting rod 22 is hinged to the support column 1, and the other end of the first connecting rod 22 is hinged to the reflector 21 belonging to the same unit reflective structure 2, allowing the included angle between the multiple reflectors 21 belonging to different unit reflective structures 2 to be adjustable. The angle locking member 3 belonging to the same unit reflective structure 2 locks the first connecting rod 22 and the reflector 21 together.

[0029] Multiple reflective units 2 are arranged sequentially around the support column 1. The support column 1 serves as the core support of the entire device, upon which all moving parts are based, ensuring the stability and integrity of the structure. The multiple independent reflective units 21 are combined into a unified system, facilitating installation and overall orientation adjustment.

[0030] The working principle of this invention is as follows: Multiple unit reflective structures 2 are arranged around a support column 1. Each reflector 21 is hinged to the support column 1 and the reflector 21 via a first connecting rod 22, allowing independent adjustment of its tilt angle, thereby changing the curvature and orientation of the overall reflective surface. Operators adjust each reflector 21 to the optimal reflection angle based on the sun's position, ensuring precise reflection of sunlight into the lower-floor interior. After adjustment, the relative positions of the first connecting rod 22 and the reflector 21 are locked and fixed by an angle locking component 3, ensuring a stable optical path and efficient introduction of natural light. This invention allows for alteration of the reflective surface curvature to meet different user needs.

[0031] The unit reflective structure 2 includes a reflector 21, a first connecting rod 22, and an angle locking component 3. Multiple reflectors 21 belonging to different unit reflective structures 2 are sequentially spliced ​​around the support column 1 along its axis. One end of the first connecting rod 22 is hinged to the support column 1, and the other end of the first connecting rod 22 is hinged to the reflector 21 belonging to the same unit reflective structure 2, so that the included angle between multiple reflectors 21 belonging to different unit reflective structures 2 can be adjusted. In this way, by adjusting the included angle, it can flexibly adapt to changes in the solar altitude angle at different seasons and times, achieve precise control of the reflected light path, and always guide the light to the target area on the lower floor, maximizing the lighting effect throughout the year.

[0032] The first link 22 and the reflector 21 are locked together by the angle locking member 3, which belongs to the same reflective structure 2. In this way, a stable and reliable mechanical connection is formed, which ensures that the reflector 21 can resist external forces and remain in the same position after being adjusted to the optimal angle, effectively preventing the reflector 21 from shaking and ensuring that the reflected light spot does not drift.

[0033] Specifically, multiple unit reflective structures 2 are arranged sequentially around the support column 1. The support column 1 serves as the core support of the entire device, upon which all moving parts are based, ensuring the stability and integrity of the structure. Multiple independent reflector units 21 are combined into a unified system, facilitating installation and overall orientation adjustment. Multiple independent reflectors 21 are spliced ​​together to form a composite reflective surface, increasing the effective reflective area and improving light-gathering efficiency. The first connecting rod 22 forms a movable support arm, with one end hinged to the support column 1, allowing the entire unit reflective structure 2 to rotate horizontally together to adjust the azimuth angle for alignment with the sun; the other end is hinged to the reflector 21, allowing the reflector 21 to independently swing its pitch angle. This allows the spatial angle of each reflector 21 to be independently and flexibly adjusted to track the sun's trajectory and reflect light to the predetermined target. After adjustment, the angle locking component 3 can firmly fix the relative angle between the reflector 21 and the first connecting rod 22, preventing the angle from changing due to wind, vibration or accidental contact, and ensuring the long-term stability and reliability of the reflected light path.

[0034] It should be noted that this device should be installed in an open area on the rooftop of a high-rise building, and the entire device should be rotated horizontally so that the composite reflective surface, composed of multiple reflective mirrors 21, is roughly facing the sun, ensuring that the mirror surface can receive sufficient light. Then, release the angle locking device 3 on each unit of the reflective structure 2. At this point, the reflective mirror 21 can swing freely around the hinge point at the end of the first connecting rod 22. By precisely manipulating each reflective mirror 21 and observing the point where the light falls in the lower-floor indoor area, its pitch angle can be adjusted one by one, ultimately ensuring that the reflected light spots from all the reflective mirrors 21 accurately converge on the indoor area requiring enhanced lighting, forming a uniform and bright illuminated surface. After adjustment, immediately tighten the angle locking device 3, using the friction generated by the locking bolts and the anti-detachment end cap 31 to firmly fix the angle, ensuring the device remains stable in outdoor environments. This device can be adjusted according to user needs. For example, in summer when the sun's altitude angle is high, users can adjust each reflector 21 to be close to the same plane, so that the reflected light is scattered into the room with a smaller focus, which not only significantly improves the amount of light, but also effectively avoids the formation of hot spots or glare due to excessive light concentration, thus balancing comfort and safety. In winter when the sun's altitude angle is low, the multiple reflectors 21 surrounding the support column 1 can be adjusted to a concave shape to enhance the collection and convergence of low-angle sunlight, making the reflected light more concentrated and with higher energy intensity, maximizing the reflection of sunlight into the room and improving the problem of insufficient lighting in low-rise buildings during the cold season. This flexible and adjustable design allows one device to be used all year round, significantly improving the lighting quality and energy efficiency of low-rise residential buildings.

[0035] Preferably, a central reflector 23 is connected to the upper end of the support column 1, and the central reflector 23 is disposed within the space formed by the plurality of reflectors 21. Since the peripheral reflectors 21 arranged around the center will create an area where light cannot be reflected, the addition of the central reflector 23 can effectively utilize this area to receive and reflect light, further increasing the total light-receiving area and efficiency of the device. This is based on multiple unit reflective structures 2 sequentially distributed around the circumference of the support column 1; and based on the central reflector 23 connected to the upper end of the support column 1, the central reflector 23 is disposed within the space formed by the plurality of reflectors 21. Thus, the plurality of reflectors 21 constitute a unified reflective surface, capable of receiving and reflecting sunlight directly hitting the top of the device, thereby further improving the light energy utilization rate.

[0036] Preferably, the centered reflector 23 is fixed to the support column 1. Fixing the centered reflector 23 to the support column 1 provides a stable optical reference and structural support for the core reflection area. This design simplifies the overall adjustment process; operators only need to adjust the peripheral movable reflectors 21 to quickly center and focus the reflected light spot, significantly reducing the complexity of multi-mirror coordinated control and improving the convenience and response speed of system adjustment. Simultaneously, the stable central structure enhances the overall anti-interference capability and reliability of the device under external forces such as wind loads, ensuring long-term operational stability.

[0037] Preferably, the angle locking component 3 includes a locking bolt and an anti-detachment end cap 31. The locking bolt passes through the first connecting rod 22 and the reflector 21, and is then connected to the anti-detachment end cap 31. The anti-detachment end cap 31 primarily prevents the locking bolt from accidentally loosening, thus improving the safety and reliability of the device during long-term outdoor use. This mechanical threaded locking method has a simple structure, high locking force, and stable performance, making it very suitable for this application scenario.

[0038] Preferably, the locking bolt is provided with a first threaded section 32 and a smooth section 33 in sequence; the first threaded section 32 is threadedly engaged with the first connecting rod 22, and the smooth section 33 is used to clearance-fit the first connecting rod 22 so that the reflector 21 can swing relative to the first connecting rod 22. When the locking bolt is loosened, the first threaded section moves away from the thread of the first connecting rod 22, and the first connecting rod 22 is sleeved on the smooth section 33. Since the smooth section 33 clearance-fits the first connecting rod 22, the first connecting rod 22 can rotate the smooth section 33 to adjust the pitch angle; when the locking bolt is tightened, the first threaded section will have relative displacement with the first connecting rod 22. At this time, the first threaded section and the first connecting rod 22 are threadedly engaged, and the hinge part of the reflector 21 and the first connecting rod 22 is pressed and fixed by friction.

[0039] Preferably, the locking bolt further comprises a second threaded section 34, wherein the first threaded section 32, the smooth section 33, and the second threaded section 34 are arranged sequentially, and the second threaded section 34 is threadedly engaged with the anti-detachment end cap 31. This design ensures that the locking bolt will not completely detach from the mechanism under vibration, avoiding the risk of parts falling off and greatly improving safety for outdoor use.

[0040] Preferably, the unit reflective structure 2 further includes a second link 24, one end of which is hinged to the first link 22, and the other end of which is hinged to a support seat 25 belonging to the same unit reflective structure 2. Multiple support seats 25 are sequentially distributed around the outer circumference of the support column 1. The second link 24 greatly enhances the structural rigidity and stability of the entire reflective unit, enabling the reflector 21 to withstand external loads such as strong winds, effectively suppressing vibrations and ensuring long-term optical path accuracy. Secondly, this structure transfers part of the bending moment borne by the first link 22 to the support seat 25, improving the stress state of the support column 1, reducing its local stress, and enhancing the overall durability and reliability of the device. It is worth noting that the addition of the second link 24 transforms the adjustment movement of the reflector 21 into a more precise and stable rotation around an axis, rather than a simple oscillation. This design makes the angle adjustment process smoother and more controllable, reduces mutual interference when adjusting multiple mirrors in a coordinated manner, and allows operators to more precisely and independently calibrate the pitch angle of each reflector 21, thereby achieving more efficient focusing and pointing of the reflected light spot, and ultimately significantly improving the light capture efficiency and overall lighting performance of the entire system.

[0041] Preferably, the plurality of reflectors 21 and the central reflector 23 are all polygonal in shape. Compared to circles or ellipses, polygons such as hexagons and triangles can be seamlessly and tightly spliced ​​together like a honeycomb, maximizing the use of space, improving the utilization rate and light-gathering efficiency of the overall reflective surface, and achieving the largest reflective area within a limited area.

[0042] Preferably, the support column 1 has a threaded rod 11, and the adjustable light reflector for enhancing daylighting on lower floors further includes a mounting base 4. The mounting base 4 has a threaded hole 41, and the threaded rod 11 is threadedly connected to the threaded hole 41. By rotating the support column 1, the absolute height and verticality of the device can be finely adjusted, thereby flexibly adapting to different installation environments and daylighting height requirements, ensuring that the reflective surface is in the optimal working posture, and improving the versatility and adaptability of the device. When cleaning or maintenance is required, the entire device can be unscrewed from the mounting base 4 for easy cleaning.

[0043] In summary, the present invention includes, but is limited to, the following beneficial effects:

[0044] 1. This utility model achieves flexible and adjustable curvature of the reflective surface through a design consisting of multiple independent reflective unit structures 2 arranged in a ring. Users can finely adjust the pitch angle of each reflector 21 according to changes in season, time, and solar altitude angle, so that the reflected light spot is precisely focused on the target area on the lower floor, significantly improving the annual lighting efficiency and the accuracy of light control.

[0045] 2. The double-link structure and modular locking mechanism greatly enhance the stability and reliability of the device. The second link 24 effectively improves the force distribution and enhances wind and vibration resistance; while the threaded locking part with anti-loosening design ensures that the reflector 21 can be firmly fixed after the angle is adjusted, guaranteeing safety and optical stability for long-term outdoor use.

[0046] 3. The overall structural design balances efficiency and adaptability. The polygonal lenses achieve seamless splicing, increasing the effective reflective area; the threaded connection between the support column 1 and the base facilitates height adjustment and quick assembly / disassembly, enabling the device to flexibly adapt to different building environments and lighting requirements, effectively reducing energy consumption and improving space utilization.
