[0027] In the related art, a baffle device is provided with a plurality of baffles for controlling the extending direction of light, so as to achieve a special light and shadow effect. Since no connection structure is provided between the baffles, light leakage occurs between adjacent baffles. The light emitted by the lamp body may leak out from the gap, and external light may interfere with the illuminated object or person from the gap, resulting in a poor light blocking effect of the baffle device.

[0028] A connecting member 400 is provided between the first baffle 310 and the second baffle 320 in the embodiment of the present application. The connecting member 400 can block the gap between adjacent baffles 300, thereby increasing the light shielding effect of the baffle device 100.

[0029] The present application intends to provide a lamp, which includes a lamp body 700 and a baffle device 100. The baffle device 100 is installed on the lamp body 700. The lamp body 700 has lamp beads. When the lamp body 700 is powered on, it can emit light through the lamp beads. The baffle device 100 is used to shield the lamp body 700 and control the angle of the light generated by the lamp body 700.

[0030] The present application also provides a baffle device 100. Please refer to Figures 1 to 3 , the baffle device 100 is applied to a lamp. The baffle device 100 has a working state and a non-working state. When the baffle device 100 is in the working state, the baffle device 100 is used to reflect the light of the lamp to concentrate the light of the lamp. When the baffle device 100 is in the non-working state, the baffle device 100 can protect and block the lamp beads of the lamp body to reduce the damage to the lamp beads caused by external sundries. The baffle device 100 includes a frame 200, baffles 300 and a connecting member 400. Exemplarily, the frame 200 is a frame having a substantially rectangular shape. The frame 200 includes a first connecting rod 210 and a second connecting rod 220. The number of both the first connecting rod 210 and the second connecting rod 220 is two. The first connecting rod 210 extends along a first direction, and the second connecting rod 220 extends along a second direction. The two first connecting rods 210 are arranged at intervals along the second direction, and the two second connecting rods 220 are arranged at intervals along the first direction. The first direction and the second direction are orthogonally arranged. The first direction is as Figure 1 shown by the arrow R1 in Figure 1 and the second direction is as shown by the arrow R2 in

[0031] The baffle 300 is installed on the frame 200. The baffle 300 includes a first baffle 310 and a second baffle 320. Both the first baffle 310 and the second baffle 320 are installed 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. Exemplarily, the number of both the first baffle 310 and the second baffle 320 is two. The two first baffles 310 are arranged at intervals along the second direction, and the two second baffles 320 are arranged at intervals along the first direction. The first baffle 310 is connected to the first link 210, and the second baffle 320 is connected to the second link 220. The first baffle 310 and the second baffle 320 enclose a working area 300a, and the light emitted by the lamp body 700 can be emitted from the working area 300a 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 shield 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. Exemplarily, when the baffle device 100 is in the non-working state, the first baffle 310 and the second baffle 320 are arranged in parallel, and the first baffle 310 and the second baffle 320 are arranged along the thickness direction of the baffle device 100. The first baffle 310 and the second baffle 320 are offset in the thickness direction, so that when the baffle device 100 is in the non-working state, the baffles 300 do not interfere with each other, the storage is relatively flat, which is conducive to packaging and carrying out.

[0032] The connecting member 400 is respectively connected to the first baffle 310 and the second baffle 320. The material of the connecting member 400 is a material that can produce elastic deformation. Exemplarily, the material of the connecting member 400 is silica gel. When the number of the baffles 300 is 4, the number of the connecting members 400 is also 4. The connecting members 400 are located at the corners of the rectangle formed by the baffles 300. When the connecting members 400 are laid flat, the shape of the connecting members 400 is approximately a quarter of a circle.

[0033] In the solution of the embodiment of the present application, the baffle device 100 is provided with a connecting member 400 respectively connecting the first baffle 310 and the second baffle 320. When the first baffle 310 and the second baffle 320 are opened, the first baffle 310 and the second baffle 320 can control the light emitted by the lamp body, so as to achieve key lighting. The connecting member 400 connecting the adjacent first baffle 310 and second baffle 320 can fill the gap between the first baffle 310 and the second baffle 320, thereby reducing the leakage of light from the gap between the first baffle 310 and the second baffle 320. Moreover, the material of the connecting member 400 is a material that can produce 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 connecting member 400 can also deform accordingly, avoiding the situation that the connecting member 400 must be removed to bend the baffle 300, thereby increasing the switching efficiency of the baffle device 100 between the working state and the non-working state.

[0034] In one embodiment, please refer to Figure 1 and Figure 4 , the connecting member 400 includes an extension member 410 and a clamping member 420. Along the width direction of the connecting member 400, clamping members 420 are connected to both ends of the extension member 410. Exemplarily, the clamping member 420 and the extension member 410 are integrally formed structures. The clamping member 420 has a clamping groove 420a, at least part of the structure of the first baffle 310 is located in the clamping groove 420a, and at least part of the structure of the second baffle 320 is located in the clamping groove 420a. Exemplarily, there is an interference fit between the baffle 300 and the corresponding clamping groove 420a, and the clamping groove 420a can produce a certain degree of elastic deformation so that the baffle 300 can extend into the inside of the clamping groove 420a, and the frictional force between the clamping groove 420a and the baffle 300 can prevent the baffle 300 from disengaging from the clamping groove 420a. The connection method between the connecting member 400 and the first baffle 310 and the second baffle 320 is relatively simple, and the clamping groove 420a can position the position of the baffle 300, and the assembly efficiency between the connecting member 400 and the baffle 300 is relatively high.

[0035] In another embodiment, please refer to Figure 2 , the clamping member 420 also has a rib 420b located in the clamping groove 420a. The rib 420b protrudes along the thickness direction of the corresponding connecting member 400. When the baffle 300 is located in the corresponding clamping groove 420a, the rib 420b abuts against the baffle 300. The rib 420b can increase the connection strength between the baffle 300 and the connecting member 400, thereby further reducing the situation of the baffle 300 disengaging from the clamping groove 420a. Exemplarily, the number of ribs 420b can be multiple, at least two ribs 420b are located in the same clamping groove 420a, and adjacent two ribs 420b are arranged at intervals.

[0036] In one embodiment, please refer to Figure 1 , the first baffle 310 and the second baffle 320 enclose a working area 300a, and a groove 400a extending along the length direction of the connecting member 400 is formed on the side of the connecting member 400 facing away from the working area 300a. Exemplarily, the length direction of the connecting member 400 intersects with the width direction of the connecting member 400, and along the length direction of the connecting member 400, the groove 400a penetrates through the connecting member 400. At least one groove 400a is located between the extension member 410 and the corresponding clamping member 420. Exemplarily, please refer to Figure 4 again, along the thickness direction of the connecting member 400, the size of the clamping member 420 is larger than that of the extension member 410, and the groove 400a is located at the junction of the clamping 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 connecting member 400. Since the baffle 300 is clamped with the clamping member 420, the baffle 300 will drive the corresponding clamping member 420 to move. The connecting member 400 has opposite first side 400c and second side 400d along the thickness direction of the connecting member 400. When the baffle device 100 is in the working state, the first side 400c is located on the side of the connecting member 400 facing the working area 300a, and the groove 400a is formed on the second side 400d. During the folding process of the baffle 300, the extension member 410 will bend towards the second side 400d, and the groove 400a can provide a deformable amount for the bending of the extension member 410, so that the extension member 410 can be folded more easily. Furthermore, during the folding process of the connecting member 400, the thickness of the baffle device 100 after folding can be reduced, so that it is easier to store.

[0037] In one embodiment, please refer to Figure 3 and Figure 4 , the number of the grooves 400a is multiple, and the multiple grooves 400a are arranged at intervals along the width direction of the connecting member 400. Exemplarily, the number of the grooves 400a is at least three. The groove 400a located between the extension member 410 and the corresponding clamping member 420 is the target groove 400b. The two target grooves 400b are respectively located at both ends of the extension member 410 along the width direction, and at least one groove 400a is located between the two target grooves 400b. Additional grooves 400a are also arranged between the target grooves 400b. When the baffle device 100 is in the working state, the grooves 400a between the target grooves 400b can reduce the stiffness of the extension member 410, so that the extension member 410 can be deformed more easily. Exemplarily, the number of the grooves 400a between the target grooves 400b is multiple, and the multiple grooves 400a are arranged at intervals along the width direction of the connecting member 400.

[0038] In one embodiment, please refer to Figure 2, the connecting member 400 includes an extension member 410 and a clamping member 420. Along the width direction of the connecting member 400, clamping members 420 are connected to both ends of the extension member 410. The clamping member 420 is detachably connected to the first baffle 310, and the clamping member 420 is detachably connected to the second baffle 320. Exemplarily, the clamping member 420 and the first baffle 310 and the second baffle 320 are in interference fit. Since the material of the connecting member 400 is a material capable of elastic deformation, the baffle 300 can be clamped with the clamping member 420 by overcoming the stiffness of the connecting member 400, and can also be disengaged from the clamping member 420 by overcoming the stiffness of the connecting member 400. The user can decide whether to disassemble the connecting member 400 and the baffle 300 according to their own needs. When the connecting member 400 and the baffle 300 are connected to each other, the baffle 300 can be directly folded, so that the baffle device 100 can be switched from the working state to the non-working state. When the connecting member 400 and the baffle 300 are disengaged from each other, when the baffle device 100 is in the non-working state, the overall thickness is relatively thin, and the occupied space of the baffle device 100 is small, which is convenient for storage.

[0039] It can be understood that other embodiments of the present application do not limit the connection manner between the clamping member 420 and the first baffle 310 and the second baffle 320. Exemplarily, the clamping member 420 is fixedly connected to the first baffle 310 and the second baffle 320.

[0040] In one embodiment, please refer to Figure 5 , the baffle 300 includes a rotating member 330 and a first shielding member 340 connected to each other. The rotating member 330 is wrapped around the frame 200, and the rotating member 330 can rotate relative to the frame 200 to drive the first shielding member 340 to rotate relative to the frame 200. Exemplarily, the first shielding member 340 is a plate-like structure. The baffle 300 can be connected to the frame 200 by screws. The screws pass through the first shielding member 340 and the rotating member 330 along the thickness direction of the baffle 300, thereby preventing the baffle 300 from being disengaged from the frame 200. The rotating member 330 and the first shielding member 340 are integrally formed structures. During the installation of the baffle 300, the operator only needs to wrap the rotating member 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. Exemplarily, the number of the rotating members 330 is multiple, and the multiple rotating members 330 are arranged at intervals along the extending direction of the first shielding member 340. The multiple rotating members 330 can increase the friction force between the corresponding baffle 300 and the frame 200, so that the baffle 300 can be relatively stably stationary relative to the frame 200.

[0041] It can be understood that both the first baffle 310 and the second baffle 320 can be integrally formed structures. The first shielding member 340 corresponding to the first baffle 310 is flush with one end of the frame 200 in the thickness direction, and the first shielding member 340 corresponding to the second baffle 320 is flush with the other end of the frame 200 in the thickness direction. Thus, the first baffle 310 and the second baffle 320 are staggered from each other in the thickness direction, reducing the interference between the first baffle 310 and the second baffle 320.

[0042] In another embodiment, please refer to Figure 6 and Figure 7 , the baffle 300 includes a clamping member 350 and a second shielding member 360. The clamping member 350 has a clamping portion 350a and a rotating portion 350b that are connected to each other. The rotating portion 350b wraps around the frame 200 and can rotate relative to the frame 200. The clamping portion 350a is used to clamp the second shielding member 360. Exemplarily, the clamping member 350 and the second shielding 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 first wrapped around the frame 200, and then the second shielding member 360 can be clamped in the clamping portion 350a of the clamping member 350. Screws are passed through the second shielding member 360 and the clamping member 350 to relatively fix the second shielding member 360 and the clamping member 350, so as to complete the installation of the baffle 300. During the processing of the baffle 300, the plate-shaped second shielding member 360 can be manufactured separately, and then the clamping member 350 and the second shielding member 360 can be spliced with each other to achieve the installation of the baffle 300. The manufacturing of the baffle 300 is relatively simple. Exemplarily, the number of the clamping members 350 is multiple, and the multiple clamping members 350 are arranged at intervals along the extending direction of the second shielding member 360.

[0043] In one embodiment, please refer to Figures 8 to 11The baffle device 100 further includes a mounting screw 500 and a clip 600. The mounting screw 500 has a thread 500a. The thread 500a is used to thread the mounting screw 500 with the lamp body. The frame 200 has a mounting hole 200a. The mounting screw 500 passes through the mounting hole 200a to fix the frame 200 relative to the lamp body. The clip 600 is located between the frame 200 and the thread 500a. The outer diameter of the clip 600 is larger than the hole diameter of the mounting hole 200a, so that the hole wall of the mounting hole 200a can limit the clip 600 from moving in the direction toward the mounting hole 200a. The inner diameter of the clip 600 is smaller than the outer diameter of the thread 500a. The clip 600 is used to inhibit the mounting screw 500 from moving in the direction toward the frame 200 along the thread 500a. In the process of twisting the mounting screw 500 to separate the mounting screw 500 from the main body of the lamp, the clip 600 can inhibit the movement of the thread 500a of the mounting screw 500, so that the thread 500a of the mounting screw 500 can be restricted to the side of the clip 600 away from the mounting hole 200a, and the mounting screw 500 cannot be separated from the frame 200. Therefore, in the process of disassembling the baffle device 100, the mounting screw 500 and the clip 600 can be moved or stored together with the frame 200, thereby reducing the problem of the mounting screw 500 being lost during the storage process. Furthermore, in the process of installing the baffle device 100, it is not necessary to first align the mounting screw 500 with and penetrate the mounting hole 200a of the frame 200, and then align the mounting screw 500 with the threaded hole of the main body of the lamp. Since the mounting screw 500 is still located in the mounting hole 200a after disassembly, it is only necessary to align the mounting screw 500 with the threaded hole of the main body of the lamp and tighten it to achieve installation.

[0044] In one embodiment, the length of the thread 500a is in the range of 3.5 mm to 5.0 mm along the length direction of the mounting screw 500. The length of the thread 500a in the appropriate range can not only ensure that the mounting screw 500 has a greater connection strength with the lamp body, but also enable the mounting screw 500 to be quickly separated from the lamp body when the mounting screw 500 is screwed out of the lamp body, so as to disassemble the baffle device 100.

[0045] In one embodiment, please refer to Figure 12, the collet 600 has a communicating opening 600a and a clamping hole 600b. The opening 600a extends from the clamping hole 600b to the outer wall of the collet 600. The aperture of the clamping hole 600b is smaller than the outer diameter of the thread 500a. The mounting screw 500 can be moved into the clamping hole 600b through the opening 600a. The collet 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 from the opening 600a of the collet 600. When the collet 600 needs to be replaced, the collet 600 can also be disengaged through the opening 600a. Exemplarily, the collet 600 is snap-fitted to the mounting screw 500. The aperture of the clamping hole 600b is substantially equal to the diameter of the stud of the mounting screw 500. When the collet 600 is snap-fitted to the mounting screw 500, the collet 600 is restricted from moving relative to the mounting screw 500 due to the frictional force between the collet 600 and the mounting screw 500, so that the collet 600 can be relatively stationary with the mounting screw 500 more stably.

[0046] 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 towards the outer edge of the collet 600, the size of the opening 600a gradually increases. The end of the opening 600a facing the outside is larger, so that the mounting screw 500 can be more easily aligned during the installation of the collet 600.

[0047] In one embodiment, please refer to Figure 10 , the mounting screw 500 further has a hand-held portion 500b. The hand-held portion 500b is located on the side of the mounting hole 200a away from the thread 500a. Along the width direction of the mounting screw 500, the size range of the hand-held portion 500b is 10mm to 12mm. Exemplarily, the width direction of the mounting screw 500 is orthogonally arranged with both the length direction and the thickness direction. The size of the hand-held portion 500b is larger, which enables the operator to hold the mounting screw 500 more stably to screw the mounting screw 500, and the mounting screw 500 has a larger outer diameter of rotation, so that the operator can rotate the mounting screw 500 with a smaller force.

[0048] In one embodiment, please refer to Figure 11, the frame 200 also includes a mounting structure 230 for assembling the mounting screw 500, the mounting hole 200a is formed in the mounting structure 230, and the mounting structure 230 is connected to the first connecting rod 210 and the second connecting rod 220 respectively. Exemplarily, in the case where the shape of the frame 200 is rectangular, the number of the mounting structures 230 is 4, and the mounting structures 230 are located at the corners of the frame 200. The first connecting rod 210 and the second connecting rod 220 are formed with a guide slope 200b at one end facing the mounting structure 230, and the guide slope 200b is used to guide the mounting screw 500 and avoid the mounting screw 500. When the operator holds the mounting screw 500 and aligns it with the mounting hole 200a, the guide slope 200b can make the mounting screw 500 positioned more quickly, and when the mounting screw 500 is twisted, the guide slope 200b can reduce the contact area between the frame 200 and the mounting screw 500, thereby reducing the friction force received by the mounting screw 500 during the twisting process.

[0049] In another embodiment, see Figure 11 Along the thickness direction of the frame 200, the side of the mounting structure 230 away from the screw thread 500a has an abutting surface 230a, and the abutting surface 230a is a plane perpendicular to the thickness direction of the frame 200. Exemplarily, the thickness direction of the frame 200 is arranged parallel to the axial direction of the mounting hole 200a. The abutting surface 230a is a plane, which can increase 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 and the abutting surface 230a abut against each other. The contact area between the mounting structure 230 and the mounting screw 500 is large, so that the pressure applied by the mounting screw 500 to the frame 200 can be reduced, and the deformation or damage of the frame 200 can be reduced.

[0050] It is understandable that other embodiments of the present application are not limited to the mounting structure 230 having the abutment surface 230a for abutting against the mounting screw 500. For example, when the mounting screw 500 is threadedly connected to the lamp body, the mounting screw 500 and the arc surface of the frame 200 abut against each other, and the force-bearing area of the frame 200 is roughly linear.
