Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting technology, and more particularly to a compact light-blocking device and its lighting fixture. Background Technology
[0002] In existing lighting designs, light shields are common components used to adjust the direction and range of light, and are widely used in stage lighting, photographic lighting, industrial lighting, and other scenarios. Traditional light shields typically employ a multi-panel structure, which unfolds and retracts through rotation or sliding to meet different light-shielding requirements. However, existing light shield designs have the following problems:
[0003] 1. When the light-blocking plates are closed, there are often large gaps between them, making it impossible to completely close them. This results in a large overall size of the lamp, which takes up a lot of space and is not conducive to transportation and storage.
[0004] 2. Due to the unreasonable design of the traditional pivoting mechanism of the light-blocking plate, interference is likely to occur when the light-blocking plate is folded, affecting the closing effect and possibly causing deformation or wear of the light-blocking plate, thus reducing its service life.
[0005] Therefore, there is an urgent need for a new type of light-blocking plate structure that can achieve complete retraction while ensuring the light-blocking effect, improve structural compactness, and optimize operational convenience, so as to meet the needs of modern lighting fixtures for lightweight, portability, and efficient adjustment. Summary of the Invention
[0006] To solve one of the above-mentioned technical problems, the present invention provides a compact light-blocking device and its lamp. The light-blocking device can be completely folded up, improving structural compactness, facilitating transportation and storage, and having a long service life.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0008] A compact light-blocking device includes a first link and a second link arranged in pairs opposite to each other. The first link and the second link are connected end to end to form a closed-loop connecting body. Both the first link and the second link are pivotally connected to a light-blocking plate. A portion of the first link protrudes to form a pivot section that is pivotally connected to the light-blocking plate. The pivot section and the second link are at different horizontal heights so that the connecting body forms a placement space for accommodating the light-blocking plate when it is retracted.
[0009] As a preferred embodiment, the first link includes a connecting section, a transition section, and a pivot section. The two ends of the pivot section are respectively connected to one end of the connecting section through the transition section, so that the pivot section and the connecting section are not at the same horizontal level. The other end of the connecting section is respectively connected to a second link on the same side of itself.
[0010] As a preferred embodiment, it is further defined that the transition section is perpendicular to the connecting section, and the transition section is also perpendicular to the pivot section.
[0011] As a preferred embodiment, it is further defined that the connection between the second link and the connecting segment, the connection between the connecting segment and the transition segment, and the connection between the transition segment and the pivot segment are all rounded with chamfers.
[0012] As a preferred embodiment, it is further defined that each of the first connecting rods is pivotally connected to the light-blocking plate via at least one pivoting assembly, and each of the second connecting rods is also pivotally connected to the light-blocking plate via at least one pivoting assembly. The connecting body is provided with limiting stops located on both sides of the pivoting assembly and capable of abutting against it, thereby restricting the axial movement of the light-blocking plate.
[0013] As a preferred embodiment, the limiting stop block is further defined as being formed by pressing a portion of the connecting body into a flat shape.
[0014] In a preferred embodiment, the pivot assembly includes a first pressure plate and a second pressure plate. A portion of the first pressure plate is bent to form a first arc-shaped segment with an arc-shaped groove, and a portion of the second pressure plate is bent to form a second arc-shaped segment with another arc-shaped groove. The openings of the arc-shaped grooves of the first and second arc-shaped segments face each other. The light-blocking plate is fixedly connected to the first and second pressure plates by fasteners. At this time, the first and second arc-shaped segments wrap around the connecting body through their own arc-shaped grooves, so that the light-blocking plate can rotate relative to the connecting body.
[0015] In a preferred embodiment, the first pressing plate further includes a straight section connected to the first arc-shaped section, and the bottom end of the light-blocking plate is provided with an arc-shaped piece. When the fastener is tightened, the straight section of the first pressing plate and the light-blocking plate are tightly fitted together, and the first arc-shaped section of the first pressing plate and the arc-shaped piece are tightly fitted together.
[0016] As a preferred embodiment, the light-blocking device further includes a base, and the base is fixedly connected to a first support block and a second support block arranged opposite to each other, and the first support block and the second support block are respectively connected to the first connecting rod and the second connecting rod in a one-to-one correspondence.
[0017] In a preferred embodiment, each of the first connecting rods and each of the second connecting rods is further defined as follows: each of the first connecting rods and each of the second connecting rods is pivotally connected to the light-blocking plate via two sets of pivoting components; a first notch is formed between the two sets of pivoting components on the first connecting rod, and a second notch is formed between the two sets of pivoting components on the second connecting rod; when the first support block is fixedly connected to the first connecting rod, the first support block is adapted to the first notch; and when the second support block is fixedly connected to the second connecting rod, the second support block is adapted to the second notch.
[0018] A lamp includes a lamp body and a light-blocking device, wherein the light-blocking device is disposed at the light outlet of the lamp body.
[0019] By adopting the above technical solution, the present invention has at least the following beneficial effects:
[0020] Because the first link and the second link are set at different heights, the light-blocking plates pivotally connected to the first link and the light-blocking plates pivotally connected to the second link are stacked in layers in the placement space after being flipped and folded up. This reduces interference between the layers of light-blocking plates and reduces damage to the light-blocking plates, thus extending their service life. After being folded up, the structure of the light-blocking device can also be made more compact, which is convenient for packaging and transportation. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0028] As attached Figure 1 To be continued Figure 4 As shown, a compact light-blocking device includes two opposing first connecting rods 1 and second connecting rods 2. The first connecting rods 1 and second connecting rods 2 are connected end-to-end to form a closed-loop connecting body 10, i.e., the first connecting rods 1 and second connecting rods 2 are integrally formed, thereby enhancing the rigidity and strength of the connecting body 10. Both the first connecting rods 1 and second connecting rods 2 are pivotally connected to light-blocking plates 3. A portion of the protrusion of the first connecting rod 1 forms a pivot section 11 that pivotally connects to the light-blocking plate 3. The pivot section 11 and the second connecting rod 2 are at different levels. The height is such that the connecting body 10 forms a placement space 100 for accommodating the light-blocking plate 3 after it is folded up. Since the first link 1 and the second link 2 are set at different heights, the light-blocking plates 3 pivotally connected to the first link 1 and the light-blocking plates 3 pivotally connected to the second link 2 are stacked in layers in the placement space 100 after being flipped up and folded up. This reduces interference between the layers of light-blocking plates 3 and reduces damage to the light-blocking plates 3, thus extending their service life. After being folded up, the structure of the light-blocking device can also be made more compact for packaging and transportation.
[0029] As attached Figure 3 As shown, the first connecting rod 1 includes a connecting section 12, a transition section 13, and a pivot section 11. The two ends of the pivot section 11 are respectively connected to one end of the connecting section 12 through the transition section 13, so that the pivot section 11 and the connecting section 12 are not at the same horizontal height. The other end of the connecting section 12 is connected to the second connecting rod 2 on the same side. Specifically, the connecting section 12 and the second connecting rod 2 are connected at the same horizontal height. The vertical or inclined design of the transition section 13 can make the heights of the pivot section 11 and the second connecting rod 2 inconsistent, thereby forming a placement space 100, making the design structure of the connecting body 10 ingenious and more rational.
[0030] As attached Figure 3As shown, the transition section 13 is perpendicular to the connecting section 12, and the transition section 13 is also perpendicular to the pivot section 11. This can reduce the risk of overturning caused by lateral forces between the connecting section 12, the transition section 13 and the pivot section 11, effectively prevent the structure of the connector 10 from bending or deforming, and improve the efficiency and reliability of the structure.
[0031] As attached Figure 3 As shown, the connection between the second connecting rod 2 and the connecting section 12, the connection between the connecting section 12 and the transition section 13, and the connection between the transition section 13 and the pivot section 11 are all rounded chamfers 101. The design of the rounded chamfers 101 can enhance the structural strength of the connecting body 10 and reduce wear. Because sharp right-angled edges are prone to cracks or deformation due to stress concentration during long-term use, the corners of the connections of each component adopt a rounded chamfer design, which can disperse stress, improve durability, and reduce the risk of wear and deformation caused by long-term use.
[0032] In this embodiment, each of the first connecting rods 1 has its pivot segment 11 pivotally connected to the light-blocking plate 3 via at least one pivot assembly 4, and each of the second connecting rods 2 is also pivotally connected to the light-blocking plate 3 via at least one pivot assembly 4. The connecting body 10 is provided with limiting stop blocks 102 located on both sides of the pivot assembly 4 and capable of abutting against it, thereby restricting the axial movement of the light-blocking plate 3, so that the light-blocking plate 3 can achieve the movement effect of being able to rotate circumferentially but not move axially. Specifically, the axial direction of the light-blocking plate 3 can be understood as the axial direction of the connecting rod pivotally connected to the light-blocking plate 3.
[0033] In this embodiment, the limiting stop block 102 is formed by pressing a portion of the connecting body 10 into a flat shape, that is, by stamping a certain position of the connecting body 10 to form a flat shape. The limiting stop block 102 and the connecting body 10 are integrated, reducing the number of parts installation steps and making the structure simple and compact.
[0034] As attached Figure 2As shown, the pivot assembly 4 includes a first pressure plate 41 and a second pressure plate 42. A portion of the first pressure plate 41 is bent to form a first arc-shaped segment 411 with an arc-shaped groove, and a portion of the second pressure plate 42 is bent to form a second arc-shaped segment 421 with another arc-shaped groove. The openings of the arc-shaped grooves in the first arc-shaped segment 411 and the second arc-shaped segment 421 face each other. The light-blocking plate 3 is fixedly connected to the first pressure plate 41 and the second pressure plate 42 by fasteners 43. At this time, the first arc-shaped segment 411 and the second... The arc-shaped segment 421 wraps around the connector 10 through its arc-shaped groove, so that the light-blocking plate 3 can rotate relative to the connector 10. That is, the arc-shaped groove of the first arc-shaped segment 411 and the arc-shaped groove of the second arc-shaped segment 421 together form a pivot hole, allowing the light-blocking plate 3 to achieve the effect of rotation. When the light-blocking plate 3 is locked with the first pressure plate 41 and the second pressure plate 42 by the fastener 43, the connector 10 can have a certain frictional force with the first pressure plate 41 and the second pressure plate 42. When the light-blocking plate 3 is adjusted to a certain angle, it achieves a hovering effect by relying on this frictional force.
[0035] As attached Figure 2 As shown, the first pressure plate 41 also includes a straight section 412 that connects to the first arc-shaped section 411. The bottom end of the light-blocking plate 3 is provided with an arc-shaped piece 31. When the fastener 43 is tightened, the straight section 412 of the first pressure plate 41 and the light-blocking plate 3 are tightly fitted together, and the first arc-shaped section 411 of the first pressure plate 41 and the arc-shaped piece 31 are tightly fitted together, which can increase the contact area between the first pressure plate 41 and the light-blocking plate 3, thereby increasing the connection strength at the pivot position of the light-blocking plate 3.
[0036] As attached Figure 1 As shown, the light-blocking device also includes a circular base 5. The base 5 is fixedly connected to a first support block 51 and a second support block 52 arranged opposite to each other. The first support block 51 and the second support block 52 are respectively connected to the first connecting rod 1 and the second connecting rod 2. The base 5 is used to fix and assemble with the lamp body, thereby completing the fixed installation of the light-blocking device.
[0037] In this embodiment, each of the first connecting rods 1 and each of the second connecting rods 2 is pivotally connected to the light-blocking plate 3 via two sets of pivoting components 4. A first notch is formed between the two sets of pivoting components 4 on the first connecting rod 1, and a second notch is formed between the two sets of pivoting components 4 on the second connecting rod 2. When the first support block 51 is fixedly connected to the first connecting rod 1, the first support block 51 is adapted to the first notch, and when the second support block 52 is fixedly connected to the second connecting rod 2, the second support block 52 is adapted to the second notch. Specifically, the first support block 51 and the first connecting rod 1 are fixed together by welding, and similarly, the second support block 52 and the second connecting rod 2 are also fixed together by welding. In addition, the first support block 51, the second support block 52, and the limiting stop block 102 cooperate to further strengthen the restriction of the axial movement of the light-blocking plate 3.
[0038] As attached Figure 5 As shown, the present invention also provides a lamp, including a lamp body and the light-blocking device, wherein the annular base 5 of the light-blocking device is disposed at the light outlet of the lamp body, thereby completing the installation of the light-blocking device.
[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
