Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting technology, and in particular to a baffle device and a lighting fixture. Background Technology
[0002] During photography, additional lighting equipment is usually required to illuminate the objects or people being photographed. To control the angle and range of the light emitted by the lighting equipment, a baffle device needs to be installed on the main body of the equipment to control the light emitted. The baffle device can also reduce ambient light pollution. The baffle device usually uses multiple baffles to block the light.
[0003] In related technologies, the light-blocking effect of baffle devices is relatively poor. Summary of the Invention
[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. In view of this, embodiments of this application aim to provide a baffle device and a lamp to increase the light-blocking effect of the baffle device.
[0005] To achieve the above objectives, one embodiment of this application provides a baffle device for use in a lighting fixture. The baffle device has a working state and a non-working state. When the baffle device is in the working state, it reflects the light from the lighting fixture to concentrate the light. The baffle device includes:
[0006] frame;
[0007] A baffle is installed on the frame. The baffle includes a first baffle and a second baffle. Both the first baffle and the second baffle are installed on the frame. The first baffle extends along a first direction, and the second baffle extends along a second direction. The second direction and the first direction are arranged to intersect.
[0008] A connector is connected to the first baffle and the second baffle respectively, and the connector is made of a material that can produce elastic deformation;

[0010] The baffle device according to the embodiments of this application has at least the following beneficial effects:
[0011] In the embodiment of this application, the baffle device is provided with a connector that connects the first baffle and the second baffle respectively. When the first baffle and the second baffle are open, the first baffle and the second baffle can control the light emitted by the lamp body, thereby achieving focused lighting. The connector connecting the adjacent first baffle and the second baffle can fill the gap between the first baffle and the second baffle, thereby reducing the leakage of light from the gap between the first baffle and the second baffle. Furthermore, the connector is made of a material that can undergo elastic deformation. When the baffle device is in a non-working state, the first baffle and the second baffle can be folded, and the connector can also deform accordingly, avoiding the situation where the connector must be removed to bend the baffle, thereby increasing the efficiency of the baffle device in switching between working and non-working states.
[0012] According to some embodiments of this application, the connector includes an extension and a snap-fit member. Along the width direction of the connector, both ends of the extension are connected to the snap-fit member. The snap-fit member has a snap-fit groove.

[0017] According to some embodiments of this application, the baffle includes a clamping member and a second blocking member. The clamping member has a clamping portion and a rotating portion connected to each other. The rotating portion is wrapped around the frame and can rotate relative to the frame. The clamping portion is used to clamp the second blocking member.
[0018] According to some embodiments of this application, the baffle device further includes a mounting screw and a clamp. The mounting screw has threads for threaded connection between the mounting screw and the lamp body.

[0046] In related technologies, baffle devices are equipped with multiple baffles to control the direction of light transmission, thereby achieving special lighting effects. However, because there is no connecting structure between the baffles, light leaks between adjacent baffles. Light emitted from the main body of the lamp may leak through the gaps, and external light may also interfere with the illuminated objects or people through these gaps, resulting in poor light-blocking effectiveness of the baffle device.
[0047] A connector 400 is provided between the first baffle 310 and the second baffle 320 in this embodiment of the application. The connector 400 can block the gap between adjacent baffles 300, thereby increasing the light-blocking effect of the baffle device 100.
[0048] This application proposes to provide a lighting fixture, which includes a lighting fixture body 700 and a baffle device 100, the baffle device 100 being mounted on the lighting fixture body 700. The lighting fixture body 700 has LEDs, and when powered on, the lighting fixture body 700 can emit light through the LEDs. The baffle device 100 is used to shield the lighting fixture body 700 from light and to control the angle of the light emitted by the lighting fixture body 700.
[0049] This application also provides a baffle device 100, please refer to [link / reference]. Figures 1 to 3 A baffle device 100 is used in a lighting fixture. The baffle device 100 has a working state and a non-working state. When the baffle device 100 is in the working state, it reflects the light from the lighting fixture to concentrate the light. When the baffle device 100 is in the non-working state, it protects and shields the lamp beads of the lighting fixture body to reduce damage to the lamp beads from external debris. The baffle device 100 includes a frame 200, a baffle 300, and a connector 400. Exemplarily, the frame 200 is a generally rectangular frame, including a first link 210 and a second link 220. There are two of each of the first and second links 210. The first link 210 extends along a first direction, and the second link 220 extends along a second direction. The two first links 210 are spaced apart along the second direction, and the two second links 220 are spaced apart along the first direction. The first and second directions are orthogonal. Figure 1 The direction indicated by the middle arrow R1, the second direction is as follows Figure 1The direction indicated by the middle arrow R2. The lamp body has a positioning groove for mounting the frame 200, and a portion of the first link 210 or the second link 220 can be snapped into the positioning groove. For example, the frame 200 is made of stainless steel, and the frame 200 has high overall strength and can still bear a large load after the frame 200 has been cut and drilled.
[0050] A baffle 300 is mounted on the frame 200. The baffle 300 includes a first baffle 310 and a second baffle 320, both of which are mounted on the frame 200. The first baffle 310 extends along a first direction, and the second baffle 320 extends along a second direction. Both the first baffle 310 and the second baffle 320 can rotate relative to the frame 200 to switch the baffle device 100 between a working state and a non-working state. For example, there are two first baffles 310 and two baffles 320. The two first baffles 310 are spaced apart along the second direction, and the two second baffles 320 are spaced apart along the first direction. The first baffle 310 is connected to a first connecting rod 210, and the second baffle 320 is connected to a second connecting rod 220. The first baffle 310 and the second baffle 320 enclose a working area 300a, from which light emitted from the lamp body 700 can be projected to the outside. When the baffle device 100 is in the working state, the first baffle 310 and the second baffle 320 open the working area 300a. When the baffle device 100 is in the non-working state, the first baffle 310 and the second baffle 320 cover the working area 300a. The first baffle 310 and the second baffle 320 can rotate in a direction away from the working area 300a to switch the baffle device 100 from the non-working state to the working state. For example, when the baffle device 100 is in the non-working state, the first baffle 310 and the second baffle 320 are arranged parallel to each other and are aligned along the thickness direction of the baffle device 100. The first baffle 310 and the second baffle 320 are misaligned in the thickness direction, so that when the baffle device 100 is in the non-working state, the baffles 300 will not interfere with each other, resulting in a flatter storage surface, which is beneficial for packaging and carrying when going out.
[0051] The connector 400 is connected to the first baffle 310 and the second baffle 320 respectively, and the connector 400 is made of a material capable of elastic deformation. For example, the connector 400 is made of silicone. When there are four baffles 300, there are also four connectors 400, located at the corners of the rectangle formed by the baffles 300. When the connectors 400 are laid flat, their shape is approximately a quarter circle.
[0052] In this embodiment, the baffle device 100 is provided with a connector 400 that connects the first baffle 310 and the second baffle 320 respectively. When the first baffle 310 and the second baffle 320 are open, the first baffle 310 and the second baffle 320 can control the light emitted by the lamp body, thereby achieving focused lighting. The connector 400 connects the adjacent first baffle 310 and the second baffle 320, filling the gap between the first baffle 310 and the second baffle 320, thereby reducing light leakage from the gap between the first baffle 310 and the second baffle 320. Furthermore, the connector 400 is made of a material capable of elastic deformation. When the baffle device 100 is in a non-working state, the first baffle 310 and the second baffle 320 can be folded, and the connector 400 can also deform accordingly, avoiding the need to remove the connector 400 to bend the baffle 300, thereby increasing the efficiency of the baffle device 100 in switching between working and non-working states.
[0053] In one embodiment, please refer to Figure 1 and Figure 4 The connector 400 includes an extension 410 and a snap-fit member 420. Snap-fit members 420 are connected to both ends of the extension 410 along the width direction of the connector 400. Exemplarily, the snap-fit member 420 and the extension 410 are integrally formed. The snap-fit member 420 has a snap-fit groove 420a, where at least a portion of the structure of the first baffle 310 and at least a portion of the structure of the second baffle 320 are located. Exemplarily, the baffle 300 and the corresponding snap-fit groove 420a are interference-fitted. The snap-fit groove 420a can undergo a certain degree of elastic deformation, allowing the baffle 300 to extend into the interior of the snap-fit groove 420a. The friction between the snap-fit groove 420a and the baffle 300 can prevent the baffle 300 from dislodging from the snap-fit groove 420a. The connection between the connector 400 and the first baffle 310 and the second baffle 320 is relatively simple, and the snap-fit groove 420a can position the baffle 300, resulting in high assembly efficiency between the connector 400 and the baffle 300.
[0054] In another embodiment, please refer to Figure 2 The snap-fit member 420 also has a protrusion 420b located within the snap-fit groove 420a. The protrusion 420b protrudes along the thickness direction of the corresponding connector 400. When the baffle 300 is located within the corresponding snap-fit groove 420a, the protrusion 420b abuts against the baffle 300. The protrusion 420b increases the connection strength between the baffle 300 and the connector 400, thereby further reducing the possibility of the baffle 300 dislodging from the snap-fit groove 420a. For example, there can be multiple protrusions 420b, with at least two protrusions 420b located within the same snap-fit groove 420a, and adjacent protrusions 420b arranged at intervals.
[0055] In one embodiment, please refer to Figure 1 The first baffle 310 and the second baffle 320 enclose a working area 300a. The connector 400 has a groove 400a extending along its length direction on the side opposite to the working area 300a. Exemplarily, the length direction of the connector 400 intersects its width direction, and the groove 400a penetrates the connector 400 along its length direction. At least one groove 400a is located between the extension 410 and the corresponding snap-fit member 420. For example, please refer to [further details omitted]. Figure 4 Along the thickness direction of the connector 400, the size of the snap-fit member 420 is larger than the size of the extension member 410, and the groove 400a is located at the junction of the snap-fit member 420 and the extension member 410. During the folding process of the baffle 300, both the first baffle 310 and the second baffle 320 will rotate relative to the connector 400. Since the baffle 300 is snapped with the snap-fit member 420, the baffle 300 will drive the corresponding snap-fit member 420 to move. The connector 400 has a first side 400c and a second side 400d along the thickness direction of the connector 400. When the baffle device 100 is in the working state, the first side 400c is located on the side of the connector 400 facing the working area 300a, and the groove 400a is formed on the second side 400d. During the folding of the baffle 300, the extension 410 bends toward the second side 400d. The groove 400a provides deformability for the bending of the extension 410, allowing it to be folded more easily. Furthermore, the folding process of the connector 400 reduces the thickness of the baffle device 100 after folding, making it easier to store.
[0056] In one embodiment, please refer to Figure 3 and Figure 4 The connector 400 has multiple grooves 400a, which are spaced apart along the width direction of the connector 400. For example, there are at least three grooves 400a. A groove 400a located between the extension 410 and the corresponding snap-fit member 420 is a target groove 400b. Two target grooves 400b are located at opposite ends of the extension 410 along its width direction, and at least one groove 400a is located between two target grooves 400b. Additional grooves 400a are also provided between the target grooves 400b. When the baffle device 100 is in operation, the grooves 400a between the target grooves 400b can reduce the stiffness of the extension 410, making it easier for the extension 410 to deform. For example, there are multiple grooves 400a between the target grooves 400b, which are spaced apart along the width direction of the connector 400.
[0057] In one embodiment, please refer to Figure 2The connector 400 includes an extension 410 and a snap-fit member 420. Snap-fit members 420 are connected to both ends of the extension 410 along the width direction of the connector 400. The snap-fit members 420 are detachably connected to the first baffle 310 and the second baffle 320. For example, the snap-fit members 420 are interference-fitted with both the first baffle 310 and the second baffle 320. Since the connector 400 is made of a material capable of elastic deformation, the baffle 300 can snap into the snap-fit member 420 while overcoming the rigidity of the connector 400, and can also disengage from the snap-fit member 420 while overcoming the rigidity of the connector 400. Users can decide whether to detach the connector 400 and the baffle 300 according to their needs. When the connector 400 and the baffle 300 are connected, the baffle 300 can be folded directly, thereby switching the baffle device 100 from a working state to a non-working state. When the connector 400 is detached from the baffle 300, the baffle device 100 is thinner and occupies less space when it is not in operation, making it easier to store.
[0058] It is understood that other embodiments of this application do not limit the connection method between the snap-fit member 420 and the first baffle 310 and the second baffle 320. Exemplarily, the snap-fit member 420 is fixedly connected to the first baffle 310 and the second baffle 320.
[0059] In one embodiment, please refer to Figure 5 The baffle 300 includes a rotating component 330 and a first blocking component 340 connected to each other. The rotating component 330 is wrapped around the frame 200 and can rotate relative to the frame 200 to drive the first blocking component 340 to rotate relative to the frame 200. For example, the first blocking component 340 is a plate-like structure. The baffle 300 can be connected to the frame 200 by screws. The screws pass through the first blocking component 340 and the rotating component 330 along the thickness direction of the baffle 300, thereby preventing the baffle 300 from detaching from the frame 200. The rotating component 330 and the first blocking component 340 are integrally formed. During the installation of the baffle 300, the operator only needs to wrap the rotating component 330 around the frame 200 to achieve the positioning and connection of the baffle 300. The connection method is simple and the assembly efficiency is high. For example, there are multiple rotating members 330, which are arranged at intervals along the extension direction of the first blocking member 340. The multiple rotating members 330 can increase the friction between the corresponding baffle 300 and the frame 200, thereby enabling the baffle 300 to remain relatively stable relative to the frame 200.
[0060] It is understood that both the first baffle 310 and the second baffle 320 can be integrally formed. The first blocking member 340 corresponding to the first baffle 310 is flush with one end of the frame 200 along the thickness direction, and the first blocking member 340 corresponding to the second baffle 320 is flush with the other end of the frame 200 along the thickness direction. Thus, the first baffle 310 and the second baffle 320 are offset from each other in the thickness direction, reducing the interference between the first baffle 310 and the second baffle 320.
[0061] In another embodiment, please refer to Figure 6 and Figure 7 The baffle 300 includes a clamping member 350 and a second blocking member 360. The clamping member 350 has a clamping portion 350a and a rotating portion 350b connected to each other. The rotating portion 350b is wrapped around the frame 200 and can rotate relative to the frame 200. The clamping portion 350a is used to clamp the second blocking member 360. Exemplarily, the clamping member 350 and the second blocking member 360 are independent structures, and the clamping portion 350a is a clamping groove. During the installation of the baffle 300, the clamping member 350 can be wrapped around the frame 200 first, and then the second blocking member 360 can be clamped in the clamping portion 350a of the clamping member 350. Screws are passed through the second blocking member 360 and the clamping member 350 to fix the second blocking member 360 to the clamping member 350, thereby completing the installation of the baffle 300. During the fabrication of the baffle 300, the second blocking member 360, which has a plate-like structure, can be fabricated separately, and then the clamping member 350 can be spliced with the second blocking member 360 to achieve the installation of the baffle 300. The fabrication of the baffle 300 is relatively simple. For example, there are multiple clamping members 350, which are arranged at intervals along the extending direction of the second blocking member 360.
[0062] In one embodiment, please refer to Figures 8 to 11The baffle device 100 also includes a mounting screw 500 and a clamp 600. The mounting screw 500 has threads 500a for threaded connection between the mounting screw 500 and the lamp body. The frame 200 has a mounting hole 200a through which the mounting screw 500 passes to fix the frame 200 relative to the lamp body. The clamp 600 is located between the frame 200 and the threads 500a. The outer diameter of the clamp 600 is larger than the diameter of the mounting hole 200a, so that the wall of the mounting hole 200a can restrict the movement of the clamp 600 in the direction toward the mounting hole 200a. The inner diameter of the clamp 600 is smaller than the outer diameter of the threads 500a, and the clamp 600 is used to inhibit the movement of the mounting screw 500 in the direction toward the frame 200 along the threads 500a. During the process of tightening the mounting screw 500 to disengage it from the lamp body, the clamp 600 inhibits the movement of the screw thread 500a. This restricts the screw thread 500a to the side of the clamp 600 away from the mounting hole 200a, preventing the screw from disengaging from the frame 200. Therefore, during the disassembly of the baffle device 100, the mounting screw 500 and clamp 600 can move or be stored along with the frame 200, reducing the risk of the screw being lost during storage. Furthermore, during the installation of the baffle device 100, it is not necessary to first align and pass the mounting screw 500 through the mounting hole 200a in the frame 200, and then align it with the threaded hole in the lamp body. Since the mounting screw 500 remains within the mounting hole 200a after disassembly, installation can be achieved simply by aligning the mounting screw 500 with the threaded hole in the lamp body and tightening it.
[0063] In one embodiment, the length of the thread 500a along the length direction of the mounting screw 500 ranges from 3.5mm to 5.0mm. Within this suitable range, the length of the thread 500a ensures a strong connection between the mounting screw 500 and the lamp body, while also allowing the mounting screw 500 to quickly separate from the lamp body when unscrewed, thus enabling the removal of the baffle device 100.
[0064] In one embodiment, please refer to Figure 12The clip 600 has an opening 600a and a clamping hole 600b that are interconnected. The opening 600a extends from the clamping hole 600b to the outer side wall of the clip 600. The diameter of the clamping hole 600b is smaller than the outer diameter of the thread 500a, allowing the mounting screw 500 to be inserted into the clamping hole 600b through the opening 600a. The clip 600 can be detachably connected to the mounting screw 500 through the opening 600a. The stud of the mounting screw 500 can enter the clamping hole 600b through the opening 600a. When the clip 600 needs to be replaced, it can also be disengaged through the opening 600a. For example, the clip 600 is engaged with the mounting screw 500. The diameter of the clamping hole 600b is substantially equal to the diameter of the stud of the mounting screw 500. When the clip 600 is engaged with the mounting screw 500, the friction between the clip 600 and the mounting screw 500 restricts the movement of the clip 600 relative to the mounting screw 500, so that the clip 600 can remain relatively stationary relative to the mounting screw 500.
[0065] In another embodiment, please refer to Figure 12 Along the radial direction of the clamping hole 600b, from the center of the clamping hole 600b toward the outer edge of the clamping piece 600, the size of the opening 600a gradually increases. The outer end of the opening 600a is larger, so that the mounting screw 500 can be aligned more easily during the installation of the clamping piece 600.
[0066] In one embodiment, please refer to Figure 10 The mounting screw 500 also has a handle 500b, which is located on the side of the mounting hole 200a opposite to the thread 500a. The size of the handle 500b ranges from 10mm to 12mm along the width direction of the mounting screw 500. For example, the width direction of the mounting screw 500 is orthogonal to both the length and thickness directions. The larger size of the handle 500b allows the operator to hold the mounting screw 500 stably for tightening it, and the larger rotational outer diameter of the mounting screw 500 allows the operator to rotate it with less force.
[0067] In one embodiment, please refer to Figure 11The frame 200 also includes a mounting structure 230 for assembling the mounting screw 500. Mounting holes 200a are formed in the mounting structure 230, which is connected to the first link 210 and the second link 220. For example, when the frame 200 is rectangular, there are four mounting structures 230 located at the corners of the frame 200. The first link 210 and the second link 220 have guide ramps 200b at their ends facing the mounting structure 230. The guide ramps 200b guide and avoid the mounting screw 500. When the operator holds the mounting screw 500 and aligns it with the mounting hole 200a, the guide ramps 200b allow the mounting screw 500 to be positioned relatively quickly. Furthermore, during the twisting process of the mounting screw 500, the guide ramps 200b reduce the contact area between the frame 200 and the mounting screw 500, thereby reducing the frictional force experienced by the mounting screw 500 during twisting.
[0068] In another embodiment, please refer to Figure 11 Along the thickness direction of the frame 200, the mounting structure 230 has an abutment surface 230a on the side opposite to the thread 500a. The abutment surface 230a is a plane perpendicular to the thickness direction of the frame 200. For example, the thickness direction of the frame 200 is arranged parallel to the axial direction of the mounting hole 200a. The plane nature of the abutment surface 230a increases the contact area between the mounting structure 230 and the mounting screw 500. When the mounting screw 500 is threadedly connected to the lamp body, the mounting screw 500 abuts against the abutment surface 230a. The larger contact area between the mounting structure 230 and the mounting screw 500 reduces the pressure exerted by the mounting screw 500 on the frame 200, thus reducing the possibility of deformation or damage to the frame 200.
[0069] It is understood that other embodiments of this application are not limited to the mounting structure 230 having an abutment surface 230a for abutting with the mounting screw 500. Exemplarily, when the mounting screw 500 is threadedly connected to the lamp body, the mounting screw 500 abuts against the arcuate surface of the frame 200, and the stress-bearing area of the frame 200 is approximately linear.
