DETAILED DESCRIPTION

[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model.

[0032] A Fresnel lens is generally a thin sheet injection-molded from polyolefin materials. One side of the lens surface is a smooth surface, and the other side is engraved with concentric circles from small to large. The Fresnel lens has a focusing effect and is therefore commonly used in the photography industry to achieve the purpose of focusing and zooming. With the development of the photography industry, on the basis of large size and large aperture, the Fresnel lens urgently needs a labor-saving and convenient focusing method to meet the needs of users.

[0033] Referring to Figure 1 , this utility model provides a lamp lens for film and television lighting for a Fresnel lens, including a housing 1, a lens assembly 2, and a motion assembly 3. The housing 1 extends in a first direction. The lens assembly 2 is arranged in the housing 1 and can reciprocally slide relative to the housing 1 in the first direction. The housing 1 and the lens assembly 2 are connected by the motion assembly 3. The lens assembly 2 reciprocally slides relative to the housing 1 in the first direction to drive the motion assembly 3 to reciprocally roll relative to the housing 1 in the first direction.

[0034] The housing 1 has a cylindrical structure. The first direction is the axial direction of the housing 1. The interior of the housing 1 is a cavity structure to form a receiving cavity for receiving the lens assembly 2. The lens assembly 2 is arranged in the receiving cavity of the housing 1. The circumferential side wall of the lens assembly 2 corresponds to the inner wall of the housing 1, and the circumferential side wall of the lens assembly 2 is connected to the inner wall of the housing 1 through the motion assembly 3. The motion assembly 3 rolls relative to the housing 1 in the first direction, so that the sliding of the lens assembly 2 relative to the housing 1 in the first direction is transitioned through the rolling of the motion assembly 3.

[0035] Thus, this utility model connects the housing 1 and the lens assembly 2 by setting the motion assembly 3. The sliding of the lens assembly 2 relative to the housing 1 is realized through the rolling of the motion assembly 3 relative to the housing 1. The motion assembly 3 and the housing 1 are in point contact, and the contact area is small. Therefore, the frictional force that needs to be overcome when the motion assembly 3 rolls relative to the housing 1 is small. Furthermore, only a relatively small force is required to achieve smooth focusing, which is not only labor-saving, but also the rolling motion of the motion assembly 3 is stable and convenient to operate.

[0036] Specifically, referring to Figure 1 and Figure 2, a rolling groove 11 extending in the first direction is provided on the inner wall of the housing 1, and the moving component 3 is reciprocally rollably provided in the rolling groove 11 to reciprocally roll relative to the housing 1 in the first direction. The arrangement of the rolling groove 11 guides the reciprocal rolling of the moving component 3, avoiding the deviation of the moving component 3 during the rolling process, thereby ensuring the smoothness of the rolling of the moving component 3, facilitating the smooth sliding of the lens assembly 2, and further achieving the purpose of smooth focusing.

[0037] The housing 1 can be a cylindrical structure formed integrally, and the rolling groove 11 penetrates the housing 1 of the cylindrical structure in the first direction. During assembly, the moving component 3 and the lens assembly 2 are first assembled and then assembled into the housing 1, or the moving component 3 and the lens assembly 2 are successively assembled into the housing 1, and the moving component 3 is located in the rolling groove 11. The housing 1 of this structure has the defect that the assembly of the moving component 3 and the lens assembly 2 is difficult, and the lens assembly 2 is easily damaged during the assembly process.

[0038] Therefore, the housing 1 of the present utility model includes a first side plate 12, a second side plate 13, and a connecting member 14 that all extend in the first direction. The first side plate 12 and the second side plate 13 are connected by the connecting member 14 to enclose a housing body. The lens assembly 2 and the moving component 3 are provided in the housing body, and the rolling groove 11 is provided in the connecting member 14. During assembly, the moving component 3 and the lens assembly 2 are first assembled and the moving component 3 is assembled into the rolling groove 11 of the connecting member 14, and then the first side plate 12, the second side plate 13, and the connecting member 14 are assembled, thereby completing the assembly of the lamp lens for film and television lighting. The housing 1 of this structure applied to the lamp lens for film and television lighting has the characteristics of simple assembly and avoids damaging the lens assembly 2.

[0039] There are two connecting members 14 provided oppositely, and the first side plate 12 and the second side plate 13 are arranged oppositely, so that the two connecting members 14 are respectively connected to the corresponding two end portions of the first side plate 12 and the second side plate 13 to assemble into the housing body. Among them, the connection between the first side plate 12 and the connecting member 14 and the connection between the second side plate 13 and the connecting member 14 are by means of clamping and / or screws to ensure the installation stability of the housing body and avoid loosening and causing the lens assembly 2 to fall off and be damaged. Moreover, the housing body is a detachable connection structure. Once a certain part is damaged, the corresponding part can be replaced in time without replacing the whole, which is beneficial to cost saving.

[0040] On the basis that the two connecting members 14 are arranged oppositely, the opposite surfaces of the two connecting members 14 are both provided with rolling grooves 11 extending in the first direction, and the two rolling grooves 11 are arranged oppositely. Two moving components 3 are provided oppositely on the radial periphery of the lens assembly 2, and the two moving components 3 are assembled into the corresponding two rolling grooves 11, thereby realizing the assembly of the lens assembly 2 in the housing 1 through the moving components 3.

[0041] The rolling groove 11 can be formed as a concave surface of the connecting member 14, or two extensions can be provided on the surface of the connecting member 14, with the rolling groove 11 formed between the two extensions. Regardless of the structure of the rolling groove 11, as long as the moving assembly 3 can roll smoothly within the rolling groove 11, it will be sufficient. Of course, the two convex extensions can act as reinforcing ribs, which, compared to the concave solution, helps to improve the mechanical strength of the connecting member 14, extend the service life of the connecting member 14, and prevent the connecting member 14 from being easily damaged and requiring frequent replacement due to repeated impact and friction during the rolling of the moving assembly 3.

[0042] Furthermore, baffles 15 are provided at both ends of the housing in the first direction. Baffles 15 overlap with the projection of lens assembly 2 in the first direction. Baffles 15 are annular in shape, with their circumference fixedly connected to the housing. The center of baffles 15 is hollowed out to avoid affecting the focusing of lens assembly 2.

[0043] Baffles 15 are provided at both ends of the housing body in the first direction to prevent the lens assembly 2 from sliding out of the housing body during focusing adjustment along the first direction.

[0044] The baffle 15 is detachably connected to the shell body by screws or snap connections, which ensures that the connection is firm and facilitates assembly and disassembly. During assembly, the motion component 3 and the lens component 2 are first assembled, and the motion component 3 is assembled into the rolling groove 11 of the connector 14. Then, the first side panel 12, the second side panel 13 and the connector 14 are assembled to form the shell body. Then, the two baffles 15 are assembled at the two ends of the shell body in the first direction, thereby completing the assembly of the lens of the lamp for film and television lighting. The shell 1 of this structure is applied to the lens of the lamp for film and television lighting, which has the characteristics of simple assembly and avoids damage to the lens component 2. In addition, the shell 1 is a detachable connection structure. Once a part is damaged, the corresponding part can be replaced in time without replacing the entire part, which is conducive to cost saving.

[0045] The above is the basic structure of the housing 1 of the lens of the lighting fixture for film and television lighting. For the lens assembly 2, refer to Figure 3 and Figure 4 The lens assembly 2 includes a mounting seat 21 and a Fresnel lens 22. The Fresnel lens 22 is clamped on the mounting seat 21. The mounting seat 21 is used to accommodate and fix the Fresnel lens 22 to ensure the stability of the Fresnel lens 22 installation.

[0046] The radial outer periphery of mounting seat 21 is adapted to the radial inner wall of the housing body, allowing mounting seat 21 to drive Fresnel lens 22 to slide smoothly within the housing body in a first direction. Motion assembly 3 is fixedly connected to mounting seat 21 and avoids Fresnel lens 22 to ensure the focusing effect of Fresnel lens 22.

[0047] The mounting base 21 is provided with at least one stopper 23 and is provided with a card slot 211 adapted to the Fresnel lens 22. The stopper 23 and the card slot 211 are arranged on the same side and partially overlap in the projection in the first direction. The Fresnel lens 22 is installed in the card slot 211 and is clamped between the mounting base 21 and the stopper 23. In this way, the clamping function of the card slot 211 and the limiting function of the mounting base 21 cooperating with the stopper 23 can ensure the stable installation of the Fresnel lens 22.

[0048] Since the Fresnel lens 22 of the present utility model is a Fresnel lens and has a circular structure, the card slot 211 is provided with a circular structure adapted to the Fresnel lens 22. Specifically, the mounting base 21 is a circular ring structure, and the inner circle of the ring is recessed to form the card slot 211. The circumferential edge of the card slot 211 is equidistantly arranged from the circumferential edge of the corresponding mounting base 21, so that the mounting base 21 can accommodate the Fresnel lens 22 with a uniform force.

[0049] The stopper 23 is arranged on the circumferential edge of the mounting base 21 and extends inward to block the circumferential edge of the card slot 211, so as to achieve the purpose of blocking the circumferential edge of the Fresnel lens 22 and cooperate with the mounting base 21 to realize the limitation of the Fresnel lens 22. There are at least two stoppers 23 and they are evenly spaced apart to ensure the limiting effect on the Fresnel lens 22.

[0050] Regarding the specific structure of the stopper 23, in the present utility model, the stopper 23 adopts a sheet structure, and its outer side is fixedly installed on the edge of the mounting base 21 through screws, and the inner side extends to block the edge of the card slot 211. During assembly, first, the Fresnel lens 22 is clamped in the card slot 211, and then the stopper 23 is fixed by screws, that is, the installation of the Fresnel lens 22 is completed.

[0051] Of course, the stopper 23 can also be formed by the circumferential edge of the moving component 3 fixedly connected to the mounting base 21 extending towards the card slot 211. No matter what structure the stopper 23 is, as long as it can meet the purpose of blocking and limiting the Fresnel lens 22.

[0052] For the moving component 3, refer to Figure 1 、 Figure 3 and Figure 5 , the moving component 3 includes a rolling member 31 and a connecting shaft 32. The rolling member 31 and the lens assembly 2 are connected by the connecting shaft 32. The rolling member 31 is reciprocally rollably arranged in the rolling groove 11 to drive the lens assembly 2 to reciprocally slide relative to the housing 1 along the first direction through the connecting shaft 32. The rolling member 31 is in point contact with the housing 1, and the contact area is small. Therefore, the rolling member 31 needs to overcome less frictional force when rolling relative to the housing 1. Furthermore, only a relatively small force is required to achieve smooth focusing, which is not only labor-saving, but also the rolling movement of the rolling member 31 in the rolling groove 11 is stable and convenient to operate.

[0053] The rolling member 31 can be a spherical structure or a wheel-shaped structure. The rolling member 31 is rotatably mounted at one end of the connecting shaft 32, and the other end of the connecting shaft 32 is fixedly connected to the mounting seat 21, so as to achieve the purpose that the rolling member 31 rolls to drive the lens assembly 2 to slide relative to the housing 1 along the first direction through the connecting shaft 32. Alternatively, the rolling member 31 is fixedly connected to one end of the connecting shaft 32, and the connecting shaft 32 is rotatably connected to the mounting seat 21, and the same purpose that the rolling member 31 rolls to drive the lens assembly 2 to slide relative to the housing 1 along the first direction can also be achieved.

[0054] On the basis of this structure, the motion assembly 3 of the present utility model further includes a connecting block 33. The connecting block 33 is arranged in the rolling groove 11 and extends to connect the lens assembly 2. The connecting block 33 is provided with a receiving position 331. The rolling member 31 is rotatably arranged in the receiving position 331 and is connected to the connecting block 33 through the connecting shaft 32. The connecting block 33 extends to be fixedly connected to the mounting seat 21 by screws, so as to convert the rolling motion of the rolling member 31 into the sliding motion of the lens assembly 2 through the connecting shaft 32. The setting of the connecting block 33 can improve the connection stability between the motion assembly 3 and the lens assembly 2.

[0055] Specifically, the receiving position 331 is located in the rolling groove 11 to ensure that the rolling member 31 in the receiving position 331 can roll along the first direction in the rolling groove 11. And, the connecting block 33 limits at least the opposite two side surfaces of the rolling member 31 to prevent the rolling member 31 from rolling out of the receiving position 331, so as to ensure the stability of the rolling motion of the rolling member 31. Based on this, the connecting shaft 32 axially penetrates the rolling member 31, the rolling member 31 rolls relative to the connecting shaft 32, and the opposite two end portions of the connecting shaft 32 are fixedly assembled to the connecting block 33.

[0056] Furthermore, there are two groups of rolling members 31. The numbers of the two groups of rolling members 31 are equal and the positions correspond one by one. The number of each group of rolling members 31 is at least two. The two groups of rolling members 31 are respectively arranged corresponding to the two side walls 17 of the rolling groove 11 and roll reciprocally along the corresponding side walls 17. Figure 5 For example, the number of each group of rolling members 31 is two. The two groups of rolling members 31 are arranged corresponding up and down. Each rolling member 31 has an independent receiving position 331, and they are separated by a connecting plate to avoid interference with each other. Each rolling member 31 is in point contact with the corresponding side wall 17. In this way, not only the friction is small, but also the points where the four rolling members 31 contact the corresponding side walls 17 form a large surface, which can make the rolling motion of the motion assembly 3 smoother, thereby further improving the smoothness of focusing.

[0057] Moreover, the two side walls 17 of the rolling groove 11 extend towards each other near the end of the lens assembly 2 to form a limiting portion 18, so that the connecting block 33 is surrounded by the housing 1, the side walls 17 and the limiting portion 18 in the rolling groove 11. In this way, the housing 1, the side walls 17 and the limiting portion 18 can limit the up, down, left and right directions of the moving assembly 3, so that the moving assembly 3 only rolls back and forth along the first direction in the rolling groove 11, avoiding the moving assembly 3 from detaching from the rolling groove 11.

[0058] In addition, the lamp lens for film and television lighting further includes a locking assembly, which includes a sliding groove 16, a lever 24 and a locking member 4. The sliding groove 16 is opened in the housing 1 and extends along the first direction. The lever 24 extends out of the sliding groove 16 from the lens assembly 2 to the outside of the housing 1, and the lever 24 can reciprocate along the sliding groove 16 to drive the lens assembly 2 to slide reciprocally relative to the housing 1 and the moving assembly 3 to roll reciprocally relative to the housing 1.

[0059] Specifically, the sliding groove 16 is opened on the first side plate 12 or the second side plate 13 along the first direction. One end of the lever 24 is fixedly connected to the mounting seat 21. The lever 24 and the mounting seat 21 can be an integral structure to improve the smoothness of the sliding drive. The other end of the lever 24 passes through the sliding groove 16 to the outside of the housing 1, and is manually operated to reciprocate along the sliding groove 16, so as to drive the lens assembly 2 to slide reciprocally relative to the housing 1, and further drive the moving assembly 3 to roll reciprocally relative to the housing 1. Since the rolling of the moving assembly 3 is a point contact with small friction, the force applied by the human hand on the lever 24 can be reduced to achieve the purpose of labor saving.

[0060] The locking member 4 is rotatably sleeved on the lever 24. The locking member 4 rotates relative to the lever 24 to be close to or away from the housing 1 to lock or unlock the lamp lens for film and television lighting. When focusing is required, the locking member 4 is manually rotated away from the housing 1 to unlock the lamp lens for film and television lighting, so that a force can be manually applied to the lever 24 to drive the lever 24 to move along the sliding groove 16 to achieve the purpose of focusing. After the focusing is completed, the locking member 4 is rotated in the reverse direction to be close to and fit against the outer surface of the housing 1 to lock the lamp lens for film and television lighting, so as to prevent the Fresnel lens 22 from zooming during use.

[0061] Wherein, the locking member 4 is threadedly connected to the lever 24 to ensure the locking degree of the locking member 4 to the lever 24.

[0062] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
