[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Please refer to the following: Figures 1-3This application discloses a light stick device 100. As a type of film and television lighting equipment, the light stick device 100 is widely used by lighting technicians due to its portability and quick operation. In practical use, users can either hold the light stick device 100 by hand or fix it in place for supplementary lighting.

[0043] In this embodiment of the application, the lamp device 100 includes a lamp 20 and a light-blocking component 10. The light-blocking component 10 is detachably connected to the lamp 20. When the two are connected, the light-blocking component 10 can partially block the light emitted by the lamp 20, so that the light emitted by the lamp 20 is emitted in a preset direction to prevent the light emitted by the lamp 20 from being too diffuse.

[0044] The lamp 20 has a large illumination area and emits relatively uniform light, thus creating a uniform light beam when providing supplemental lighting. It is understood that the light source of the lamp 20 is an LED light source, which has advantages such as energy efficiency, excellent light quality, and long lifespan. The lamp 20 is rod-shaped or cylindrical to ensure a relatively regular shape and a large illumination area; this embodiment does not specifically limit the shape of the lamp 20. The lamp 20 includes a first retaining groove 20A.

[0045] The light-blocking assembly 10 includes a light-blocking component 11 and a snap-fit ​​component 12. The light-blocking component 11 is used to partially block the light emitted by the lamp 20. Specifically, the light-blocking component 11 can be made of plastic, making it lightweight and easy for users to carry. The light-blocking component 11 is detachably connected to the lamp 20. Thus, when it is necessary for the light emitted by the lamp 20 to be emitted in a preset direction, the light-blocking component 11 can be connected to the lamp 20, so that the light-blocking component 11 can block and reflect the light emitted by the lamp 20, allowing the light emitted by the lamp 20 to be emitted in the preset direction. The detachable connection method between the light-blocking component 11 and the lamp 20 includes, but is not limited to, snap-fit ​​connection, threaded connection, etc.

[0046] The snap-fit ​​component 12 can be made of plastic to make it heavier and lower in cost. The snap-fit ​​component 12 can be rotatably connected to the light-blocking component 11, for example, the snap-fit ​​component 12 can be rotatably connected to the light-blocking component 11 via a pivot (not shown in the figure).

[0047] The latching member 12 includes a latching part 121 and an unlocking part 122, which are located at opposite ends of the latching member 12 along its extension direction. The latching part 121 can be in the form of a snap-fit ​​for engaging with the first latching slot 20A. It is understood that by engaging the latching part 121 with the first latching slot 20A, the light-blocking member 11 and the lamp 20 can be detachably connected. That is, when the latching part 121 is engaged with the first latching slot 20A, the light-blocking member 11 and the lamp 20 are connected, and when the latching part 121 is disengaged from the first latching slot 20A, the light-blocking member 11 and the lamp 20 are detached.

[0048] The unlocking part 122 can be in the form of a button. It is understood that the locking member 12 is rotatably connected to the light-blocking member 11 at its center along its extension direction. Therefore, when the user presses the unlocking part 122, the locking member 121 is lifted up, thus separating from the first locking groove 20A. Based on this, when the unlocking part 122 is pressed, the locking member 12 can rotate relative to the light-blocking member 11, causing the locking member 121 to disengage from the first locking groove 20A, so that the light-blocking member 11 can be removed from the lamp 20.

[0049] The technical solution of this application adopts the cooperation between the snap-fit ​​part 121 of the snap-fit ​​component 12 and the first snap-fit ​​groove 20A. When the user needs to remove the light-blocking component 11 from the lamp 20, he only needs to press the unlocking part 122 of the snap-fit ​​component 12 to make the snap-fit ​​part 121 disengage from the first snap-fit ​​groove 20A. Then the light-blocking component 11 can be directly separated from the lamp 20. This makes the operation more labor-saving and convenient for the user, effectively improving the user's disassembly efficiency and enhancing the user experience.

[0050] Please refer to the following: Figures 2-4 In some embodiments, the light-blocking member 11 includes a bracket 111 and two light-blocking plates 112, with the snap-fit ​​member 12 rotatably connected to the bracket 111. The bracket 111 can be generally square in shape, making the shape more regular and easier to manufacture. The bracket 111 can be detachably connected to the lamp 20 by engaging with the first snap-fit ​​groove 20A of the lamp 20 through the snap-fit ​​part 121 of the snap-fit ​​member 12.

[0051] Two light-blocking plates 112 are rotatably connected to both sides of the bracket 111 along its width direction, and both light-blocking plates 112 can be rotated relative to the bracket 111 by a set angle and then stay at the corresponding position of the set angle.

[0052] In some exemplary structures, the side of the bracket 111 is provided with two spaced-apart first connecting portions, and a notch is formed between the two first connecting portions. The outer side of the light-blocking plate 112 is provided with a second connecting portion, which is disposed within the notch. The baffle assembly also includes a threaded component, a nut, a first washer, and a second washer. Part of the first washer is disposed within the first connecting portion and part within the second connecting portion. Part of the second washer is disposed within the second connecting portion and part within the other first connecting portion. After the screw passes through the first connecting portion, the first washer, the second connecting portion, the second washer, and the other first connecting portion in sequence, it is threadedly connected to the nut. Thus, the threaded component can act as a pin to realize the rotational connection between the light-blocking plate 112 and the bracket 111. The frictional force generated between the first washer and the first and second connecting portions, as well as the frictional force generated between the second washer and the second and other first connecting portions, achieves a damping effect. The light-blocking plate 112 can be stably stopped at the corresponding position of the set angle after being rotated by a set angle.

[0053] In this way, the user can adaptively control the rotation of the light-blocking plate 112 according to the required light emission angle, and make the light-blocking plate 112 stay in the required position, so as to control the angle at which the light emitted by the rod lamp 20 finally shines to the outside. The operation is convenient and the structure is simple.

[0054] Please refer to the following: Figures 3-5 In some embodiments, the surface of the unlocking part 122 facing away from the light-blocking member 11 is provided with a protrusion 1221. It can be understood that when the user presses the unlocking part 122, the surface being pressed is the surface of the unlocking part 122 facing away from the light-blocking member 11. Based on this, the protrusion 1221 in this embodiment can provide better friction when the user presses the unlocking part 122, and can also distinguish the different positions of the pressing part and other parts of the latching member 12 by the different tactile feel, reducing the probability that the user will have difficulty finding the unlocking part 122 when operating blindly.

[0055] Please refer to the following: Figures 4-6 In some embodiments, the light-blocking member 11 has a rotating post 1111 on its side, and the light-blocking member 11 and the rotating post 1111 can be an integrally formed structure; the snap-fit ​​member 12 has an adapter hole 123, specifically, along the extending direction of the snap-fit ​​member 12, the adapter hole 123 is located between the snap-fit ​​part 121 and the unlocking part 122.

[0056] The rotating post 1111 is inserted into the adapter hole 123 and can rotate relative to the adapter hole 123, so that the snap-fit ​​member 12 can rotate relative to the light-blocking member 11 around the central axis of the adapter hole 123. In this embodiment, the rotating post 1111 is directly formed by the light-blocking member 11, and the snap-fit ​​member 12 can be rotatably connected to the light-blocking member 11 through the cooperation of the rotating post 1111 and the adapter hole 123. In this way, there is no need to set up a special rotating shaft, thereby reducing the number of parts of the light-blocking assembly 10 and facilitating the assembly of the light-blocking assembly 10.

[0057] Alternatively, the snap-fit ​​member 12 may have a rotating post 1111 and the side of the light-blocking member 11 may have an adapter hole 123. This embodiment does not limit this.

[0058] Please refer to the following: Figures 4-7 Furthermore, the light-blocking assembly 10 also includes a limiting member 13, which passes through the rotating column 1111 to restrict the rotating column 1111 from disengaging from the adapter hole 123.

[0059] For example, when the rotating column 1111 is made of plastic, the limiting member 13 can be a self-tapping screw. In this way, the limiting member 13 can be fixedly inserted into the rotating column 1111 without forming a threaded structure inside the rotating column 1111. In another embodiment, when the rotating column 1111 is made of metal and the rotating column 1111 can have internal threads, the limiting member 13 can be a screw with external threads, and the limiting member 13 can be fixedly inserted into the rotating column 1111 through the threaded engagement of the external threads and internal threads.

[0060] Therefore, in this embodiment, after the rotating column 1111 is inserted into the adapter hole 123, the limiting member 13 can be inserted into the rotating column 1111 to ensure the stability of the rotating column 1111 inserted into the adapter hole 123. Furthermore, this embodiment can reduce the number of parts of the light blocking component 10 without the need to additionally set a nut to thread it to the limiting member 13, and facilitates the assembly of the light blocking component 10.

[0061] Please refer to the following: Figures 4-6 as well as Figure 8 In some embodiments, the side of the light-blocking member 11 is formed with a receiving groove 111A, and part of the unlocking part 122 is disposed in the receiving groove 111A.

[0062] The light-blocking assembly 10 also includes a reset member 14, which can be in the form of a compression spring, a spring sheet, etc., and this embodiment does not limit this. The reset member 14 is disposed in the receiving groove 111A, with one end abutting against the bottom wall of the receiving groove 111A and the other end abutting against the unlocking part 122.

[0063] The reset member 14 is used to provide a restoring force to the unlocking part 122 when it is released, thereby driving the unlocking part 122 to reset. In actual use, when the unlocking part 122 is pressed, the reset member 14 will be deformed by the compression between the unlocking part 122 and the bottom wall of the receiving groove 111A; when the unlocking part 122 is released, the reset member 14 is released and returns to its original shape, thus providing a restoring force to the unlocking part 122.

[0064] With this configuration, after each unlocking operation, when the user releases the unlocking part 122, the reset component 14 will automatically drive the unlocking part 122 to reset, effectively improving the user experience.

[0065] Please refer to the following: Figures 3-4 Furthermore, the first snap-fit ​​slot 20A includes at least two, and the at least two first snap-fit ​​slots 20A are respectively disposed on opposite sides of the light bar 20 along its width direction. The snap-fit ​​member 12 includes at least two, and the at least two snap-fit ​​members 12 are respectively disposed on opposite sides of the light-blocking member 11 along its width direction. Among them, the snap-fit ​​portion 121 of one snap-fit ​​member 12 is engaged with one first snap-fit ​​slot 20A.

[0066] In this way, the stability of the connection between the light-blocking component 11 and the lamp 20 can be further improved by the one-to-one engagement of at least two snap-fit ​​parts 121 and at least two first snap-fit ​​slots 20A, thereby preventing the light-blocking component 10 from detaching from the lamp 20 during the use of the lamp device 100 and ensuring the stability of the supplementary light.

[0067] To further improve the stability of the connection between the light-blocking component 11 and the light bar 20, please refer to the following: Figures 3-4 as well as Figure 9 Furthermore, the light bar 20 also has a second snap-fit ​​groove 20B, which is located on the front side of the light bar 20 along its length. A snap-fit ​​block 15 is provided on the front side of the light-blocking member 11 along its length, and the snap-fit ​​block 15 is used to engage with the second snap-fit ​​groove 20B. This arrangement further enhances the stability of the connection between the light-blocking member 11 and the light bar 20 through the engagement of the snap-fit ​​block 15 and the second snap-fit ​​groove 20B, effectively reducing the risk of separation between the light-blocking member 11 and the light bar 20.

[0068] It is understandable that the opening of the second latching slot 20B is located along the length of the lamp 20. Therefore, during the actual disassembly process, the user can first press the unlocking part 122 of the two latching pieces 12, so that the latching parts 121 of the two latching pieces 12 are separated from the two first latching slots 20A. Then, the user can control the light blocking member 11 to move along the length of the lamp 20, so that the latching block 15 can be pulled out from the opening of the second latching slot 20B, so that the latching block 15 can be disengaged from the second latching slot 20B. The operation is simple and quick.

[0069] Please refer to the following: Figures 3-5 In some embodiments, the snap-fit ​​portion 121 is formed with a first guide surface 1211, which is used to guide and cooperate with the groove wall of the first snap-fit ​​groove 20A during the snap-fit ​​portion 121 snapping into the first snap-fit ​​groove 20A. In this way, the smoothness of the snap-fit ​​portion 121 snapping into the first snap-fit ​​groove 20A can be improved, thereby improving the smoothness of the user's operation when connecting the light-blocking member 11 to the lamp 20.

[0070] Please refer to the following: Figure 4 and Figure 9 In some embodiments, the snap-fit ​​block 15 has a second guide surface 151, which guides the snap-fit ​​block 15 into the second snap-fit ​​groove 20B during the snap-fit ​​block 15 snaps into the second snap-fit ​​groove 20B. This improves the smoothness of the snap-fit ​​block 15 snapping into the second snap-fit ​​groove 20B, thereby improving the smoothness of the user's operation when connecting the light-blocking member 11 to the lamp 20.

[0071] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the light-blocking member 11 can be connected to the light bar 20 in a front-to-back direction and can be separated from the light bar 20 in a back-to-front direction.

[0072] In daily use, when a user places the lamp 20 on a table or other surface, the back of the lamp 20 is usually placed on the surface, not the front, i.e., the light-emitting surface. Therefore, if the light-blocking member 11 is connected to the lamp 20 from back to front and separated from it from the lamp 20 from front to back, the user needs to remove the lamp 20 to complete the above operation. Based on this, in this embodiment, the light-blocking member 11 is connected to the lamp 20 from front to back and separated from it from the lamp 20 from back to front. Therefore, when the back of the lamp 20 is placed on the surface, the user can complete the connection or disassembly of the light-blocking member 11 without removing the lamp 20 from the surface, improving the user experience. It should be noted that the front-back direction described above is parallel to the thickness direction of the lamp 20.
