It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0035] Currently, existing photography light lens modules have relatively limited beauty functions, requiring users to purchase multiple modules to meet their multifunctional beauty needs. This not only causes inconvenience to users but also increases their purchase costs. In response to this, embodiments of the present invention provide a photography light lens module to enhance its versatility and meet users' diverse needs.
[0036] Referring to FIG. 1 and FIG. 2 , a photographic light lens module proposed in this embodiment includes:
[0037] Shell 1;
[0038] The rotating drum 2 is rotatably disposed in the housing 1;
[0039] The lens barrel 3 extends into the rotating barrel 2 and is connected to the rotating barrel 2 through a spiral guide structure 10. The lens barrel 3 is provided with a lens 4;
[0040] The adjusting member 5 is provided on the outer periphery of the rotating drum 2 and partially protrudes from the outer shell 1 . The adjusting member 5 is connected to the rotating drum 2 via a transmission assembly 20 .
[0041] The photographic light lens module of this embodiment is applied to photographic lights. In this embodiment, the outer shell 1 is cylindrical, hollow inside, and open at both ends. The interior of the outer shell 1 is used to install the rotating barrel 2. Specifically, the rotating barrel 2 is rotatably arranged inside the outer shell 1, and the rotating barrel 2 can rotate relative to the outer shell 1. The interior of the rotating barrel 2 is hollow, and the lens barrel 3 extends into the interior of the rotating barrel 2. Optionally, the lens barrel 3 includes a barrel body 31 and a pressure cover 32. The lens 4 is arranged at the end of the barrel body 31 and is located between the barrel body 31 and the pressure cover 32. The barrel body 31 extends into the interior of the rotating barrel 2, and the lens 4 and the pressure cover 32 are exposed to the rotating barrel 2. The lens barrel 3 can move axially relative to the rotating barrel 2. Specifically, the lens barrel 3 is connected to the rotating barrel 2 through a spiral guide structure 10. When the rotating barrel 2 rotates, the lens barrel 3 is driven to move by the spiral guide structure 10, thereby driving the lens 4 to move back and forth to achieve focusing. The adjustment member 5 of this embodiment is used to drive the rotating barrel 2 to rotate. Specifically, the adjustment member 5 is disposed on the outer periphery of the rotating drum 2 and connected to the rotating drum 2 via a transmission assembly 20. The transmission assembly 20 can be a gear transmission structure, such as a bevel gear assembly, a rack and pinion structure, or the like. Alternatively, the adjustment member 5 is a knob. Thus, rotating the adjustment member 5 drives the rotating drum 2 via the transmission assembly 20, resulting in smooth and labor-saving transmission. Furthermore, the adjustment member 5 partially protrudes from the housing 1, isolating it from the internal components of the lens module, thereby blocking heat transfer and preventing burns during focusing.
[0042] When the lens module of this embodiment is used for focusing a photographic light, the adjusting member 5 is rotated. The adjusting member 5 drives the rotating barrel 2 to rotate via the transmission assembly 20. The rotating barrel 2 drives the lens barrel 3 to move via the spiral guide structure 10, thereby moving the lens 4 to achieve focusing. Compared with the prior art focusing method of directly manually rotating the threaded housing 1, the embodiment of the present invention uses the adjusting member 5 to drive the lens barrel 3 to move, which makes focusing smoother and more labor-saving. At the same time, the adjusting member 5 partially protrudes from the housing 1. When focusing, the hand does not directly contact the housing 1, preventing burns during focusing and improving safety.
[0043] 2 , in some embodiments, the spiral guide structure 10 includes a matching guide groove 101 and a guide member 102 , and the guide groove 101 is spirally arranged around the axis of the rotating drum 2 ;
[0044] The guide groove 101 is provided on the inner side wall of the rotating barrel 2, and the guide member 102 is provided on the outer peripheral wall of the lens barrel 3;
[0045] Alternatively, the guide groove 101 is provided on the outer peripheral wall of the lens barrel 3 , and the guide member 102 is provided on the inner side wall of the rotating barrel 2 .
[0046] In this embodiment, the rotating barrel 2 and the lens barrel 3 are connected via a spiral guide structure 10. The spiral guide structure 10 includes a guide groove 101 and a guide member 102. The guide member 102 is adapted to the guide groove 101 and can be accommodated within the guide groove 101 and move along the guide groove 101, thereby achieving relative movement between the lens barrel 3 and the rotating barrel 2. The guide groove 101 is a spiral groove spirally arranged around the axis of the rotating barrel 2, and the guide member 102 is a protrusion adapted to the spiral groove. In one embodiment, the guide groove 101 is provided on the inner sidewall of the rotating barrel 2, spirally arranged around the inner sidewall of the rotating barrel 2. A plurality of guide members 102 are provided, and the plurality of guide members 102 are spaced apart on the outer peripheral wall of the lens barrel 3. Each guide member 102 is accommodated within the guide groove 101. As the rotating barrel 2 rotates, the plurality of guide members 102 move along the guide grooves 101, causing the lens barrel 3 to move relative to the rotating barrel 2, thereby achieving focusing. In another embodiment, a plurality of guide members 102 are provided on the inner side wall of the rotating barrel 2, and a guide groove 101 is provided on the outer peripheral wall of the lens barrel 3. The guide groove 101 is spirally arranged around the outer peripheral wall of the lens barrel 3. Each guide member 102 is accommodated in a guide groove 101. Thus, when the rotating barrel 2 rotates, the plurality of guide members 102 move along the guide groove 101, pushing the lens barrel 3 to move relative to the rotating barrel 2, thereby achieving focusing.
[0047] Continuing with FIG. 2 , in some embodiments, the transmission assembly 20 includes a connected active member 201 and a driven member 202. The active member 201 is connected to the adjustment member 5, and the driven member 202 is disposed on the periphery of the rotating drum 2. Optionally, the active member 201 includes a bevel gear, and the driven member 202 includes a ring gear meshing with the bevel gear, with the ring gear disposed around the periphery of the rotating drum 2.
[0048] In this embodiment, the adjusting member 5 drives the rotating cylinder 2 to rotate through the transmission assembly 20, wherein the adjusting member 5 is a knob structure and the transmission assembly 20 is a gear transmission structure. Specifically, the transmission assembly 20 includes an active member 201 and a driven member 202, wherein the active member 201 includes a bevel gear, and the driven member 202 includes a ring gear arranged on the outer periphery of the rotating cylinder 2. The bevel gear has a connecting shaft and a gear portion, and the connecting shaft of the bevel gear is connected to the adjusting member 5. The gear portion of the bevel gear meshes with the ring gear on the outer periphery of the rotating cylinder 2, and the diameter of the bevel gear is smaller than the diameter of the ring gear. In this way, when the adjusting member 5 is rotated, the bevel gear rotates, and through the gear meshing transmission, the ring gear is driven to rotate, thereby driving the rotating cylinder 2 to rotate. This embodiment adopts gear transmission, which makes the transmission smoother and more precise, and the focusing is more labor-saving, thereby improving the user experience.
[0049] Please continue to refer to Figure 2. In some embodiments, the outer wall of the lens barrel 3 is provided with at least one limit member 311, and the housing 1 is provided with a retaining ring 11 at one end along the axial direction of the lens barrel 3. The retaining ring 11 is used to block the limit member 311 to limit the movement of the lens barrel 3.
[0050] In this embodiment, the retaining ring 11 on the outer shell 1 is used to block the limiter 311 to limit the movement of the lens barrel 3 within the rotating barrel 2 and prevent the lens barrel 3 from escaping from the rotating barrel 2. Specifically, at least one limiter 311 is provided. The limiter 311 is a protrusion provided on the outer peripheral wall of the lens barrel 3. When multiple limiters 311 are provided, the multiple limiters 311 are spaced apart along the circumference of the lens barrel 3. The retaining ring 11 is part of the outer shell 1 and is provided at the end of the rotating barrel 2. When the lens barrel 3 moves to the position of maximum focal length during focusing, the limiter 311 on the lens barrel 3 contacts the retaining ring 11, thereby limiting the further movement of the lens barrel 3 and preventing the lens barrel 3 from escaping from the rotating barrel 2.
[0051] Optionally, the outer wall of the lens barrel 3 is provided with at least one avoiding groove 312 , the limiting member 311 is provided in the avoiding groove 312 , and the height of the limiting member 311 is not higher than the notch of the avoiding groove 312 .
[0052] In this embodiment, the avoidance groove 312 on the outer peripheral wall of the lens barrel 3 is used to accommodate the limiter 311 to prevent the limiter 311 from interfering with the rotating cylinder 2. Specifically, at least one avoidance groove 312 is provided, formed on the outer peripheral wall of the lens barrel 3. The avoidance groove 312 is a strip-shaped groove and extends along the axial direction of the lens barrel 3. When multiple avoidance grooves 312 are provided, the multiple avoidance grooves 312 are spaced apart along the circumference of the lens barrel 3, and each avoidance groove 312 accommodates one limiter 311. In this embodiment, the height of the limiter 311 is no higher than the notch of the avoidance groove 312. In other words, it can be understood that the limiter 311 does not protrude from the outer peripheral wall of the lens barrel 3, thereby preventing the limiter 311 from interfering with the rotating cylinder 2.
[0053] Continuing with Figure 2, in some embodiments, the inner sidewall of the lens barrel 3 is provided with a heat-insulating layer 6. In this embodiment, the heat-insulating layer 6 is used to block the heat emitted by the camera light, further preventing burns. In this embodiment, the heat-insulating layer 6 is provided on the inner sidewall of the lens barrel 3, blocking the transfer of heat to the lens barrel 3, the rotating barrel 2, and the housing 1, significantly reducing the risk of burns and improving the user experience. The heat-insulating layer 6 can be made of a material with a low thermal conductivity, such as silicone or ceramic.
[0054] Referring to Figure 3, in some embodiments, the rotating drum 2 is provided with a plurality of heat dissipation holes 21, which are spaced apart along the circumference of the rotating drum 2. In this embodiment, the heat dissipation holes 21 are used to dissipate heat generated by the video light. Specifically, the plurality of heat dissipation holes 21 are spaced apart along the circumference of the rotating drum 2. This increases the heat dissipation area and heat dissipation channels, improves the heat dissipation performance of the lens module, and further reduces the risk of burns.
[0055] Please refer to Figure 4. In some embodiments, the lens barrel 3 includes a barrel body 31 and a pressure cover 32. The end face of the barrel body 31 is provided with a mounting position 313 for mounting the lens 4. The pressure cover 32 is provided at the end of the barrel body 31 and presses the lens 4 onto the mounting position 313.
[0056] In this embodiment, the lens 4 is mounted between the end of the barrel 31 and the gland 32 via a mounting position 313. Specifically, the mounting position 313 includes a plurality of steps spaced circumferentially along the end surface of the barrel 31. The lens 4 rests on the steps, and the gland 32 is pressed against the lens 4, thereby securing the lens 4 to the end of the barrel 31. Optionally, the gland 32 and the barrel 31 are fastened by screws.
[0057] Optionally, the lens 4 is a Fresnel lens. The Fresnel lens is relatively thin, which makes the lens module structure compact and lightweight, thereby improving the portability of the photographic light.
[0058] Optionally, the lens 4 is a Fresnel convex lens.
[0059] The present invention further provides a photography light, which includes a photography light body and a photography light lens module as described in the above embodiment. The lens module is arranged on one side of the photography light body in the light emitting direction.
[0060] The specific structure of the photography light lens module refers to the above embodiments. Since this photography light adopts all the technical solutions of all the above embodiments, it at least has all the technical effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0061] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
