Description

Technical Field

[0001] This utility model relates to the field of visual design technology, and in particular to a nighttime visual lighting device for cultural exhibition halls. Background Technology

[0002] As the core carrier of urban cultural dissemination, the cultural exhibition hall bears the important mission of showcasing historical context, artistic achievements, and technological development. The various historical artifacts and exquisite handicrafts carefully displayed inside are not only a direct presentation of the local profound cultural heritage and unique historical charm, but also a deep interpretation and communication of cultural content.

[0003] For example, the Chinese patent published on April 11, 2023, entitled "Anti-glare Adjustable Lighting Device" (publication number CN218845929U), discloses a snap-fit ​​main body, a threaded lighting lamp, and an anti-glare adjustment mechanism. The snap-fit ​​main body has a threaded lighting lamp in the middle of its interior, and the threaded lighting lamp has an anti-glare adjustment mechanism on its outer walls. The anti-glare adjustment mechanism includes an adjustment shell, an anti-slip outer ring, an anti-glare inner wall ring, a threaded inner groove, and a lampshade. The adjustment shell has an anti-slip outer ring on its outer walls, an anti-glare inner wall ring on its inner walls, a threaded inner groove on one side of the anti-glare inner wall ring, and a lampshade on the other side of the anti-glare inner wall ring.

[0004] While the aforementioned technologies achieve the effect of preventing glare, they still require manual adjustment of the lights, especially at night when the exhibition hall is even darker. This necessitates repeated adjustments based on actual lighting conditions to achieve the goal of preventing glare. Furthermore, the technologies are cumbersome to operate, which reduces their overall practicality. Utility Model Content

[0005] The main purpose of this utility model is to provide a nighttime visual lighting device for cultural exhibition halls, which can automatically adjust the anti-glare structure and is easy to operate.

[0006] The technical solution of this utility model is as follows:

[0007] A nighttime visual lighting device for a cultural exhibition hall includes a lighting lamp and a lamp base. The lighting lamp is located at the center of the lamp base, and the lamp base is provided with an anti-glare structure, which includes a movable rod and a light-shielding component.

[0008] The lamp base has a movable channel perpendicular to its bottom. The movable rod is slidably connected in the movable channel. The end of the light-shielding component facing the lighting lamp is hinged to the movable rod. The side of the movable channel facing the ground has an annular support point. The annular support point abuts against the light-shielding component. The lamp base has a linear drive structure for driving the light-shielding component to reciprocate relative to the movable channel.

[0009] In one possible implementation, the cross-section of the annular fulcrum is an arc-shaped structure;

[0010] The light-shielding assembly includes a light-shielding adjustment frame, a light-shielding sheet, and a torsion spring. The light-shielding adjustment frame is hinged to the movable rod, and a torsion spring is provided at the hinge. The light-shielding sheet is located on the side of the light-shielding adjustment frame facing the lighting lamp.

[0011] In one possible implementation, the lamp base has a mounting groove on the side away from the ground, and the linear drive structure includes a linear driver, a sliding light rod, and a nut seat;

[0012] The linear actuator is located in the mounting slot. The output shaft of the linear actuator is connected to the mounting slot and the nut seat. The nut seat is fixedly connected to the inner wall of the movable rod. One end of the sliding light rod is fixedly connected to the ground-facing side of the mounting slot, and the other end passes through the nut seat and is rotatably connected to it. The ground-facing end of the sliding light rod is fixedly connected to the lamp base.

[0013] In one possible implementation, the cross-section of the movable channel is an annular structure, and the movable channel is arranged around the center of the lighting lamp and on its outer ring.

[0014] In one possible implementation, the light-shielding sheet has a magnetic male piece for fixing the light-shielding sheet on the side facing the lamp base, and the lamp base has a magnetic female piece corresponding to the position of the magnetic male piece, with the magnetic male piece and the magnetic female piece magnetically engaged.

[0015] In one possible implementation, the cross-section of the light-shielding sheet is an arc-shaped structure.

[0016] In one possible implementation, the light-shielding sheet has a dark-colored light-absorbing velvet layer on the side facing the lighting lamp.

[0017] In one possible implementation, there are several sliding light rods arranged sequentially around the center of the lighting lamp.

[0018] The working principle and beneficial effects of this utility model are as follows:

[0019] Start the equipment; the lighting provides basic illumination. The operator presses the remote control to signal the linear drive mechanism. The linear actuator drives the nut seat to slide along the sliding rod, causing the movable rod to slide within the movable channel. As the movable rod slides upward, the light-shielding adjustment bracket and the light-shielding plate retract into the movable channel. The torsion spring provides support for the light-shielding adjustment bracket. After adjusting to a suitable light-shielding angle using the torsion spring support and the annular fulcrum, stop operating the remote control.

[0020] This embodiment incorporates an anti-glare structure within the base, and a linear drive structure enables the coordinated adjustment of multiple components, improving adjustment efficiency and avoiding repeated adjustments. This not only enhances overall convenience but also ensures compatibility with various scenarios, making this invention highly practical. Attached Figure Description

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-5 As shown in the figure, this embodiment proposes a nighttime visual lighting device for a cultural exhibition hall. Its structure includes a lighting lamp 1 and a lamp base 2. The lighting lamp 1 is located at the center of the lamp base 2 to ensure uniform illumination. The lamp base 2 is provided with an anti-glare structure 3, which includes a movable rod 31 and a light-shielding component 32. The lamp base 2 is provided with a linear drive structure 4 for adjusting the light-shielding component 32.

[0032] The lamp base 2 has a movable channel 21 perpendicular to its bottom. The movable rod 31 is slidably connected to the movable channel 21. The movable channel 21 provides a precise and stable linear trajectory for the movement of the movable rod 31, ensuring that the movable rod 31 can only move in a direction perpendicular to the bottom of the lamp base 2. The movable channel 21 has an annular support point 211 on the side facing the ground. Its surface is relatively smooth, and the cross-section of the annular support point 211 is an arc-shaped structure. The arc-shaped structure of the annular support point 211 can better fit the light-shielding component 32, reducing friction on the contact surface, while providing an arc-shaped guide for the rise and fall of the light-shielding component 32.

[0033] The light-shielding component 32 is hinged to the movable rod 31 at the end facing the lighting lamp 1. The hinge has significant damping, allowing the light-shielding component 32 to change angle relative to the movable rod 31 during movement, enabling it to expand and retract. This embodiment provides four light-shielding components 32, which can be distributed circumferentially around the lighting lamp 1, effectively preventing glare from multiple angles emitted by the lamp. Users can set different numbers of light-shielding components 32 according to actual anti-glare requirements, which will not be elaborated further in this embodiment.

[0034] In this embodiment, the light-shielding component 32 includes a light-shielding adjustment frame 321, a light-shielding sheet 322, and a torsion spring 323. The light-shielding sheet 322 is directly responsible for blocking, reflecting, or absorbing light to achieve anti-glare. The light-shielding sheet 322 is located on the side of the light-shielding adjustment frame 321 away from the lighting lamp 1 and is always in the path where light needs to be blocked.

[0035] The light-shielding adjustment frame 321 is hinged to the movable rod 31, and a torsion spring 323 is provided at the hinge. This torsion spring 323 acts as an elastic driving element, using elastic potential energy to keep the light-shielding adjustment frame 321 in the open state and providing elastic support for the frame, thus ensuring that the light-shielding sheet 322 remains in contact with the annular fulcrum 211. The compression of the torsion spring 323 varies with the opening angle of the light-shielding adjustment frame 321, providing a support force that matches the angle.

[0036] In this embodiment, the thickness of the light-shielding plate 322 is less than the radial width of the movable channel 21. Its end away from the ground can move upward with the movable rod 31. When needed, by setting reasonable dimensions, the light-shielding plate 322 can be fully or partially inserted into the movable channel 21 to achieve the required rotation angle. Furthermore, through the support force provided by the torsion spring 323 and the limiting of the annular fulcrum 211, the light-shielding plate 322 can achieve different light-shielding angles with different heights of the movable rod 31.

[0037] In this embodiment, the cross-section of the light-shielding plate 322 is arc-shaped. The arc-shaped structure can more effectively absorb stray light reflected from the surface of the light-shielding plate 322. If the angle of a flat light-shielding plate is not appropriate, it may reflect unwanted light towards the human eye, forming secondary glare. The arc-shaped design can guide this reflected light into the lamp or other directions for absorption through its curvature. At the same time, compared with a straight edge, the arc-shaped structure can produce a more gradual and natural transition of shadow boundaries when blocking light, making the light attenuation in the blocked area smoother and more visually comfortable.

[0038] In this embodiment, the light shield 322 is provided with a dark light-absorbing velvet layer 324 on the side facing the lighting lamp 1. The dark fabric itself has the effect of absorbing light, and after the light enters the velvet fiber bundle, it will undergo multiple reflections and refractions between the fibers. Each time it is reflected or refracted, some light energy is absorbed by the fibers. Any light that shines on the side of the light shield 322 facing the lighting lamp will be almost completely absorbed by this dark light-absorbing velvet layer 324. This reduces the possibility that the light shield 322 itself will become a reflection source and reflect the light to the direction of the human eye, causing secondary glare.

[0039] The activity channel 21 has an annular support point 211 on the side facing the ground. The surface of the annular support point 211 is smooth, and the cross-section of the annular support point 211 is an arc-shaped structure. The arc-shaped structure of the annular support point 211 can better fit the light shield 322, reduce the friction of the contact surface, and provide an arc-shaped guide for the light shield 322 to rise and fall.

[0040] In this embodiment, the lamp base 2 has a mounting groove 22 on the side away from the ground. The mounting groove 22 is equipped with a linear drive structure 4. The mounting groove 22 provides installation space for the linear drive structure 4, making the linear drive structure 4 internal, protecting the linear drive structure 4 from external influences, and extending its service life. The linear drive structure 4 includes a linear actuator 41, a sliding rod 42, and a nut seat 43.

[0041] The linear actuator 41 is located in the mounting slot 22. The output shaft of the linear actuator 41 is connected to the mounting slot 22 and the nut seat 43, which can directly transmit the linear driving force to the nut seat 43. The nut seat 43 is fixedly connected to the inner wall of the movable rod 31, which transmits the driving force of the linear actuator 41 to the movable rod 31, causing it to slide in the movable channel 21, thereby realizing the unfolding and retraction of the light-shielding component 32.

[0042] In this embodiment, there are several sliding light rods 42, all arranged sequentially around the center of the lighting lamp 1. They can constrain the nut seat 43 from multiple directions, reducing its deviation to one side when sliding. At the same time, the orderly arrangement of the sliding light rods 42 can make the guiding force distribution more uniform, ensuring that the movable rod 31 moves smoothly along the annular channel and ensuring the concentricity of the operation of the light-shielding component 32.

[0043] One end of the sliding light rod 42 is fixedly connected to the ground-facing side of the mounting groove 22, and the other end passes through and is rotatably connected to the nut seat 43. This provides guidance and reduces wobbling for the nut seat 43, ensuring smooth sliding of the movable rod 31. The ground-facing end of the sliding light rod 42 is fixedly connected to the lamp base 2, and the fixed connection at both ends improves the stability of this embodiment.

[0044] In this embodiment, the cross-section of the active channel 21 is an annular structure, and the active channel 21 is arranged around the center of the lighting lamp 1 and on its outer ring. The annular structure ensures that the movement of all light-shielding components 32 is symmetrical around the center of the lighting lamp 1, and at the same time, it can ensure that glare control or light blocking around the lighting lamp is uniform and without blind spots.

[0045] In addition, as an option, in this embodiment, a magnetic male piece 51 for fixing the light-shielding sheet 322 can be provided on the side of the light-shielding sheet 322 facing the lamp base 2. Its core function is to fix the light-shielding sheet 322 and prevent it from loosening when not in operation. The lamp base 2 is provided with a magnetic female piece 52 corresponding to the position of the magnetic male piece 51. The two are magnetically coupled, and without any mechanical structure, sufficient attraction can be generated to stably fix the light-shielding sheet 322 on the lamp base, which facilitates quick positioning and fixing.

[0046] The working process of this embodiment is as follows:

[0047] 1. When adjustment is required, the operator gives the linear actuator 41 an upward movement signal. At this time, the linear actuator 41 receives the start signal, its output shaft rotates, and drives the nut seat 43 to slide upward along the sliding rod 42, which in turn drives the movable rod 31 fixed to the nut seat 43 to slide upward in the annular movable channel 21.

[0048] Since the movable rod 31 is hinged to the light-shielding component 32, the light-shielding component 32 will move upward together.

[0049] The torsion spring 323 continuously provides an outward force to the light-shielding plate 322, ensuring that the light-shielding plate 322 always abuts against the annular fulcrum 211. At the same time, the upward force of the movable rod 31 and the force of the annular fulcrum 211 abutting against the light-shielding plate 322 work together.

[0050] If a magnetic attraction structure is provided, the magnetic male piece 51 will be disengaged from the magnetic attraction range of the magnetic female piece 52, and the edge of the magnetic female piece 52 is provided with a ramp to facilitate the disengagement of the light-shielding piece 322. The light-shielding piece 322 can smoothly leave the magnetic female piece 52 along the ramp.

[0051] 2. When the movable rod 31 slides upward, since the thickness of the light-shielding plate 322 at the end away from the ground is less than the radial width of the movable channel 21, its end can slide upward with the movable rod 31 and thus enter the movable channel 21.

[0052] Under the action of the annular fulcrum 211, the hinge point of the light-shielding plate 322 moves upward, pushing the light-shielding plate 322 to rotate towards the lighting lamp 1. This allows the light-shielding plate 322 to achieve different light-shielding angles depending on the position of the movable rod 31. Therefore, based on the actual situation, a signal is sent to the linear actuator 41 to adjust the required light-shielding angle.

[0053] 3. When a reset is required, the operator gives a downward movement signal to the linear driver 41. At this time, the linear driver 41 receives a start signal, its output shaft rotates, and drives the nut seat 43 to slide downward along the sliding light rod 42, which in turn drives the movable rod 31 fixed to the nut seat 43 to slide downward in the annular movable channel 21. The light shield 322 begins to reset under the action of the torsion spring 323.

[0054] At this time, the arc-shaped structure of the ring fulcrum 211 provides a guide for the light shield 322 to return to its downward position, so that the magnetic male piece 51 on the light shield 322 gradually approaches the slope passing through the edge of the magnetic female piece 52 as the movable rod 31 moves downward. After the two are fully attracted, the linear actuator 41 stops.

[0055] At this time, the light-shielding component 32 is fixed to the lamp base 2 through the magnetic male piece 51 and the magnetic female piece 52, so as not to affect the normal lighting of this embodiment.
