Description

Technical Field

[0001] This utility model belongs to the field of photographic equipment technology, and in particular relates to a snoot and a modeling light. Background Technology

[0002] To precisely control the direction and range of modeling lights, creating a spot of light with a clearly defined illumination boundary, a snoot (or spotlight) is typically used as an auxiliary tool. A typical snoot's internal structure, arranged along the direction of light propagation, includes a filter, an aperture diaphragm (or aperture assembly), and a lens module. The aperture diaphragm is the key component controlling the amount of light passing through (light intensity). Photographers often need to adjust the aperture size or shape according to different shooting requirements.

[0003] Currently, there are two main technical methods for adjusting the aperture of the aperture stop:

[0004] 1. Replaceable aperture diaphragms: This method achieves aperture variation by replacing aperture diaphragm components with different fixed aperture sizes. However, this method has significant drawbacks: it is cumbersome to operate, photographers need to carry multiple spare aperture diaphragms of different sizes, which is inconvenient to use and carry, and it cannot achieve continuous and rapid aperture adjustment.

[0005] 2. Knob and Gear Adjustment: This method uses an external knob to drive an internal gear mechanism, which in turn drives the blades of the aperture module (usually composed of multiple blades), thereby continuously changing the aperture size. While overcoming the disadvantage of needing to carry multiple parts in the replaceable type, this method also has significant drawbacks: the operating position is limited, the knob is usually fixed in a specific position on the stylist, and the photographer can only operate it from specific angles and positions. In complex lighting environments or when the stylist is inconveniently installed, adjustment is difficult, it is prone to impact, has a high risk of water leakage, and its appearance is rather obtrusive. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the existing technology by providing a beam slant and a decorative light.

[0007] This utility model provides a beam strapper, including an aperture module, a filter element, and a lens module;

[0008] The aperture module includes a fixed cylinder, an annular movable component, multiple aperture blades, an active operating ring, and a driven ring. The fixed cylinder has an incident end for light to enter and an exit end for light to exit. The annular movable component is located inside the fixed cylinder and can rotate relative to the fixed cylinder. The multiple aperture blades are located inside the fixed cylinder and arranged in a ring array. One end of each aperture blade is rotatably connected to the fixed cylinder, and the other end is radially movable and connected to the annular movable component. When the annular movable component rotates, it can drive each aperture blade to rotate around one end, while the other end moves radially. The active operating ring is sleeved outside the fixed cylinder and has multiple active magnets arranged in a ring array. The driven ring is sleeved inside the fixed cylinder and has multiple driven magnets arranged in a ring array. The driven ring is connected to the annular movable component.

The annular fixing member has a limiting opening for the lever to pass through.

[0020] Optionally, the beam tube further includes an incident connecting tube, which is connected to the incident end.

[0021] Optionally, the filter element is detachably connected to the incident end;

[0022] The incident connecting cylinder and the fixed cylinder together form an insertion groove for inserting the filter element.

[0023] Optionally, the two opposite edges of the filter lens are provided with a first snap-fit ​​structure;

[0039] Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0041] This utility model embodiment provides a beam strapper.

[0042] Please see Figures 1 to 8The beam tube includes an aperture module 100, a filter 200, and a lens module 300.

[0043] The aperture module 100 includes a fixed cylinder 110, an annular movable member 120, multiple aperture blades 130, an active operating ring 140, and a driven ring 150. The fixed cylinder 110 has an incident end for light to enter and an exit end for light to exit. The annular movable member 120 is located inside the fixed cylinder 110 and can rotate relative to the fixed cylinder 110. The multiple aperture blades 130 are located inside the fixed cylinder 110 and arranged in a ring array. One end of each aperture blade 130 is rotatably connected to the fixed cylinder 110, and the other end is radially movable and connected to the annular movable member 120. When 120 rotates, it can drive each aperture blade 130 to rotate around one end, while the other end moves radially. The active operating ring 140 is sleeved on the outside of the fixed cylinder 110 and has multiple active magnets 141 arranged in a ring array. The driven ring 150 is sleeved on the inside of the fixed cylinder 110 and has multiple driven magnets 151 arranged in a ring array. The driven ring 150 is connected to the ring movable member 120. During the rotation, the active operating ring 140 can drive the ring movable member 120 to rotate through the magnetic attraction between the active magnets 141 and the driven magnets 151.

[0044] The filter element 200 is connected to the incident end and is used to selectively control the light to exit through the exit end. The filter element 200 is an optical element whose core function is to selectively allow light of a specific wavelength (or color) to pass through, while blocking or reducing light of other unwanted wavelengths (or colors). In actual use, different filter elements 200 can be replaced as needed.

[0045] The lens module 300 is connected to the output end and is used to shape the light emitted from the output end. In this embodiment, the lens module 300 is detachably connected to the output end. Preferably, the lens module 300 is detachably connected to the fixing cylinder 110, so that different lens modules 300 can be replaced according to actual needs. It should be noted that the lens module 300 includes at least one lens and a lens mounting cylinder.

[0046] During use, it is necessary to achieve precise and smooth adjustment of the size of the light-transmitting hole.

[0047] Based on the above-mentioned structural design of this utility model, compared with the traditional replaceable aperture diaphragm solution, this snoot achieves continuous and stepless adjustment of the aperture size, significantly improving the flexibility and precision of illumination control without interrupting use or replacing parts. Compared with the adjustment method that relies on physical gear meshing transmission, this design offers greater operational freedom, allowing users to easily start, stop, and fine-tune the aperture at any angle. It also boasts a simpler appearance; the magnetic drive eliminates the need for openings, racks, or exposed transmission components on the outer wall of the fixed cylinder 110, effectively simplifying the external structure, maintaining the integrity and aesthetic appeal of the snoot's appearance, improving reliability, and enhancing waterproof performance. The non-contact transmission avoids mechanical wear, reducing the risk of transmission jamming or failure due to dust or oil intrusion, and improving long-term reliability.

[0048] Please see Figure 2 and Figure 4 In this embodiment of the present invention, the inner wall of the fixed cylinder 110 is provided with an annular mounting portion 111; the aperture module 100 also includes a connecting ring 160, which is located inside the fixed cylinder 110 and connected to the annular mounting portion 111. The connecting ring 160 and the inner wall of the fixed cylinder 110 together form an annular cavity for placing the driven ring 150.

[0049] Based on this, a ring-shaped housing cavity is constructed using the natural gap between the inner wall of the fixed cylinder 110 and the connecting ring 160. This layout eliminates the need for additional installation space inside the fixed cylinder 110, effectively compressing the overall radial dimension and making the internal structure of the slant tube more compact, adapting to more confined installation scenarios. Simultaneously, the closed housing cavity isolates the driven ring 150 from external dust and debris, preventing foreign matter from affecting the magnetic attraction performance of the driven magnet 151 or causing the driven ring 150 to jam, significantly reducing the risk of component wear and extending the service life of the core components of the aperture module 100. Furthermore, this structure, through the dual limiting of the inner wall of the fixed cylinder 110 and the connecting ring 160, ensures that the driven ring 150 always remains coaxial with the active operating ring 140, guaranteeing stable and precise magnetic attraction between the active magnet 141 and the driven magnet 151, avoiding problems such as transmission jamming and adjustment misalignment caused by the offset of the driven ring 150.

[0050] Please see Figure 2 , Figure 4 and Figure 6 In this embodiment of the invention, the driven ring 150 and the annular movable member 120 are connected by a lever 170; the connecting ring 160 has a movable groove 1601 through which the lever 170 passes. The design of the movable groove 1601 provides movement space for the lever 170 without compromising the overall structural strength of the connecting ring 160, allowing the connecting ring 160 to be fixedly installed without interfering with internal transmission, which helps to reduce the structural size.

[0051] Please see Figure 2 , Figure 4 and Figure 6 In this embodiment of the present invention, one side of the connecting ring 160 is provided with an annular outer connecting part 161 protruding outward, and the annular outer connecting part 161 is connected to the annular mounting part 111.

[0052] The other side of the connecting ring 160 has an annular inner connection part 162 protruding inward;

[0053] The aperture module 100 is located inside the connecting ring 160 and connected to the inner ring portion 162. One end of each aperture blade 130 is rotatably connected to the inner ring portion 162.

[0054] Based on this, there is no need to set up an additional radial support structure inside the fixed tube 110. The radial installation range of the aperture module 100 can be directly limited by the protrusion size of the annular inner part 162, which effectively compresses the radial space occupied by the aperture module 100 inside the fixed tube 110, making the internal structure layout of the entire beam tube more compact, which helps to reduce the overall size of the product and adapt to more narrow installation scenarios.

[0055] Please see Figure 2 , Figure 4 and Figure 6 In this embodiment of the invention, the aperture module 100 further includes an annular fixing member 180 and a limiting retaining ring 190. The annular fixing member 180 is connected to the annular inner part 162 and extends from the outer annular surface to form a cylindrical receiving part 181. The annular movable member 120 and each aperture blade 130 are located within the receiving part 181. One side of one end of each aperture blade 130 is rotatably connected to the annular fixing member 180, and the other side of the other end is rotatably connected to the receiving part 181, which is engaged by the annular movable member 120 and the limiting retaining ring 190, thus limiting the annular movable member 120 within the receiving part 181. The annular fixing member 180 has a limiting opening 1801 for the lever 170 to pass through. Based on this, the receiving part 181 centrally encapsulates the core components of the aperture module 100, reducing the radial space occupied, while strictly limiting the movement range of the blades within the receiving part 181 to avoid interference with other components.

[0056] Please see Figure 1 and Figure 2 In this embodiment of the invention, the beam slant also includes an incident connecting tube 400, which is connected to the incident end. The incident connecting tube 400 is detachably or fixedly connected to the incident end of the fixed tube 110 (e.g., by threads or snaps), facilitating docking with the light source equipment.

[0057] Please see Figures 1 to 4In this embodiment of the invention, the filter element 200 is detachably connected to the incident end; the incident connecting cylinder 400 and the fixing cylinder 110 together form an insertion groove for inserting the filter element 200. Based on this, during the replacement process, different types (such as color temperature filters and neutral density filters) of filter elements 200 can be replaced simply by inserting and removing them.

[0058] Please see Figure 3 and Figure 4 In this embodiment of the present invention, the two opposite edges of the filter lens 200 are provided with a first snap-fit ​​structure 210;

[0059] The beam slant also includes two second elastic snap-fit ​​structures 112 located in the insertion slots. When the filter 200 is inserted into the insertion slot, the two second elastic snap-fit ​​structures 112 are elastically snapped into a first snap-fit ​​structure 210 respectively.

[0060] Based on this, the snap-fit ​​connection eliminates the need for screws or other fasteners, simplifying the installation and removal process of the filter element 200. Users can operate it with one hand, improving efficiency.

[0061] Please see Figure 2 and Figure 4 In this embodiment of the invention, the beam snoot also includes a diffuser 600, which is installed inside the fixed cylinder 110 and located between the filter lens 200 and the aperture module 100. First, the diffuser 600 (such as frosted glass or a microstructured optical sheet) can homogenize the light after it has been processed by the filter lens 200, thus avoiding the problem that the filter lens 200 cannot handle uneven light. Second, the diffuser 600, located between the filter lens 200 and the aperture module 100, can also work with the lens module 300 to seal the fixed cylinder 110.

[0062] In this embodiment, the diffuser 600 is disposed on the annular mounting portion 111.

[0063] This utility model also proposes a decorative lamp, which includes a beam snoot. The specific structure of the beam snoot is as described in the above embodiments. Since this decorative lamp adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
