[0028] The focusing mechanism is an accessory of an optical instrument and plays a role in adjusting the focal length in the optical instrument. A focusable fill light is a lamp that improves the shooting effect by adjusting the light and field of view. It makes the shooting picture clearer and brighter through the combination of different light sources and lamps. There are two main types of focusable fill lights: reflective and transmissive. The reflective fill light uses a reflector or a reflective cover to reflect light onto the subject, making the picture light uniform and soft; the transmissive fill light uses a transmissive lens to allow more light to pass through, making the photo clearer and brighter. The focusing shading structure in the prior art adopts a sleeve structure, which has a complex structure, cumbersome assembly, and is inconvenient to produce. At the same time, the fill light is prone to light leakage.
[0029] See also Figure 1 to Figure 7 To solve the above problems, the present application provides a focusable fill light 10. Figure 1 and Figure 2 1 is a schematic structural diagram of a focus-adjustable fill light 10 according to an embodiment; Figure 3 , Figure 4 and Figure 5 is a schematic diagram of a partial structure of a focus-adjustable fill light 10 according to an embodiment; Figure 6 It is an enlarged view of a partial structure of a focus-adjustable fill light 10 according to an embodiment;
[0030] Figure 7The schematic diagram of the partial structure of a focusable fill light 10 of an embodiment is shown. The focusable fill light 10 comprises a housing 20, a lampshade 30, a lamp body 40, a folding cover 50 and a knob 60. The lampshade 30 is fixed to one end of the housing 20 and is provided with a condenser lens. The lamp body 40 is axially slidably connected to the inside of the housing 20. A light-emitting component is provided in the lamp body 40, and the light-emitting side of the light-emitting component faces the condenser lens. The folding cover 50 is located inside the housing 20. One end of the folding cover 50 is fixedly connected to the lampshade 30, and the other end is fixedly connected to the lamp body 40. The folding cover 50 can be axially telescopically deformed and is arranged around the interval between the lampshade 30 and the lamp body 40. The knob 60 is rotatably connected to the outside of the housing 20 and is transmission-connected to the lamp body 40. The knob 60 is used to drive the lamp body 40 to move relative to the lampshade 30 along the axial direction.
[0031] See also Figure 1 to Figure 7In the focusable fill light 10 provided in the present application, the focusable fill light 10 includes a housing 20, a lampshade 30, a lamp body 40, a folding cover 50 and a knob 60. The housing 20 constitutes the main external structure of the focusable fill light 10. The lamp body 40 can be arranged in the housing 20. The lampshade 30 is fixed to one end of the housing 20 and is provided with a focusing lens. The focusing lens is an optical element that can focus light to a specific point or area. Its working principle is based on the refraction phenomenon of light. When light passes through the focusing lens, the light will be refracted due to the different refractive index of the lens material and the surrounding environment, so that the originally scattered light can be concentrated. In some embodiments, the housing 20 can be made of metal material, such as aluminum alloy material. The aluminum alloy material has high strength and can withstand large external forces to ensure the stability and durability of the housing 20. At the same time, it has good corrosion resistance and can be used for a long time in a humid or corrosive environment without being easily damaged. It is light in weight, which can not only ensure the stability and durability of the device, but also be easy to carry and use. In some embodiments, the lamp body 40 is slidably connected to the inside of the housing 20 along the axial direction, and a light-emitting component is provided in the lamp body 40, and the light-emitting side of the light-emitting component faces the focusing lens. The housing 20 is provided with a slide groove 31 in the axial direction, and the slide groove 31 can be set into different shapes as needed, such as a rectangle. In some embodiments, the slide groove 31 is set to be a rectangle, and the extension direction of the slide groove 31 is parallel to the extension direction of the length of the housing 20. The folding cover 50 is located inside the housing 20, one end of the folding cover 50 is fixedly connected to the lampshade 30, and the other end is fixedly connected to the lamp body 40. The folding cover 50 can be axially telescopically deformed and is arranged around the interval between the lampshade 30 and the lamp body 40. The folding cover 50 of the fill light is an accessory for the fill light, which is mainly used to adjust and control the scattering range and intensity of light. The main function of the folding cover 50 is to control the scattering range of light, so that it can more flexibly adapt to different shooting needs. By folding and unfolding, users can easily adjust the coverage and intensity of light to obtain better light and shadow effects. In photography, the folding hood 50 is often used in a variety of scenes such as portrait photography, product photography and landscape photography. It can provide soft and even light, eliminate shadows and improve shooting effects. When installing, make sure that the folding hood 50 fits tightly against the fill light to reduce light leakage.
[0032] See also Figure 1 and Figure 2The knob 60 is rotatably connected to the outside of the housing 20 and is in transmission connection with the lamp body 40. The user can adjust the fill light by rotating the knob 60. The knob 60 can drive the lamp body 40 to move axially relative to the lampshade 30. The focusing knob 60 is closely matched with the sleeve and is detachable, which is convenient for production, disassembly, maintenance and replacement by later users. When the user uses the focusable fill light 10, the focus adjustment process of the fill light can be achieved by rotating the knob 60, and the lamp body 40 can be driven to move axially relative to the lampshade 30 by rotating the knob 60. The folding cover 50 can be axially telescopically deformed and is arranged around the interval between the lampshade 30 and the lamp body 40. The folding cover 50 can be stretched and expanded, or contracted and shortened. It moves and zooms together with the focusing module, plays a shading role, and can prevent the light of the lamp beads from leaking out from the air outlet on the side of the middle tube.
[0033] See also Figure 3 and Figure 4 One end of the folding cover 50 is fixed to the lampshade 30 by a plurality of glue nails 71, and the other end is fixed to the lamp body 40 by a plurality of glue nails 71. The glue nails 71 can be fixed to the lamp body 40 by a rivet buckle 43 structure. The rivet buckle 43 is a connecting piece, which is mainly used to fix and connect various components. The rivet buckle 43 usually consists of a rivet and a buckle 43. One end of the rivet is connected to the buckle 43, and the other end is connected to the component to be fixed, and the component is tightened and fixed by axial force. The buckle 43 is used to assemble on the component to be fixed, ensuring that the rivet can firmly connect the folding cover 50 and the lampshade 30, thereby improving the structural stability of the adjustable focus fill light 10.
[0034] Continue reading Figure 3 and Figure 4The folding cover 50 includes a first connecting section 51, a folding section 52 and a second connecting section 53 which are connected in sequence. In some embodiments, the first connecting section 51, the folding section 52 and the second connecting section 53 can be integrated into an integrated structure to increase the compactness of the internal structure of the focusable fill light 10. Specifically, the first connecting section 51 is connected to the lampshade 30, the second connecting section 53 is connected to the lamp body 40, and the folding portion is arranged between the first connecting section 51 and the second connecting section 53. In some embodiments, the folding section 52 can be arranged in a W-shaped structure, the folding section 52 has a bellows structure, and the cross section of the folding section 52 is circular, which is easy to achieve compression and stretching. The folding section 52 can be made of silicone material. Since the silicone material is relatively soft and the hardness is easy to adjust, the tensile force and the compressive force acting on the silicone part are very small, so that the knob 60 can be adjusted easily and effortlessly. The thickness of the tube wall of the folding section 52 is 0.3 cm to 0.5 cm. The folding section 52 with a smaller wall thickness is easily compressed and stretched, so that the user can stretch or shrink the folding section 52 when using the focusable fill light 10. In some embodiments, the first connecting section 51 and the second connecting section 53 can be made of silicone material to facilitate the compression and stretching of the folding cover 50.
[0035] See also Figure 7 The inner wall of the lampshade 30 is provided with a slide groove 31, and a spring piece 32 is fixed in the slide groove 31. The spring piece 32 in the slide groove 31 is semi-enclosed. A support column 45 is provided on the side of the lamp body 40 close to the lampshade 30. The support column 45 extends into the slide groove 31 and moves synchronously with the lamp body 40 along the axial direction. A hook portion is provided at the tail of the spring piece 32 to abut against the support column 45. The spring piece 32 is directly opposite to the support column 45 along the axial direction, and can abut against the support column 45 when the lamp body 40 moves close to the lampshade 30 to achieve position limiting, which can ensure that the deformation of the spring piece 32 is within the normal range, and prevent it from being crushed by the lampshade 30 and causing the function to fail.
[0036] In some embodiments, the tail end of the spring piece 32 has a hook structure 321, which is arched on the side away from the lamp body 40. The end face of the hook structure 321 is axially opposite to the support column 45 to ensure that the spring piece 32 deforms within a normal range and prevents the spring piece 32 from being crushed by the lampshade 30 and causing the protective function to fail.
[0037] See also Figure 3 , Figure 4 , Figure 5 and Figure 6, the outer side of the lamp body 40 is provided with a wiring groove 42 extending in the axial direction, and the wiring groove 42 is used to standardize and fix the wires inside the focusable fill light 10, such as the power line and the data line. The wiring groove 42 is arranged on the outer side of the lamp body 40, and the top of the wiring groove 42 is provided with a plurality of buckles 43 arranged in the axial direction. The wiring connected to the light-emitting component is placed in the wiring groove 42 and is buckled by the buckle 43 to ensure the neatness and safety of the line. The wire can be used to connect the lamp bead board and the control board. In some embodiments, the wiring groove 42 is provided on the wire bracket 80, and the wire bracket 80 is connected to the lamp body 40. One end of the wire bracket 80 is fixed to the tail of the radiator, and the other end is fixed to the head of the radiator. The wire bracket 80 can be fixedly clamped to the radiator by two screws, and formed into one with the radiator module to ensure good rigidity and strength. In some embodiments, a sloped retaining wall connected to the wiring groove 42 may be provided at the end of the wiring groove 42, which may also limit the direction of the wires so that the wires do not affect the normal movement of the rack 44 and the gear. For example, the outer side of the lamp body 40 is provided with a wiring groove 42 extending in the axial direction, and the top of the wiring groove 42 is provided with three buckles 43 arranged in the axial direction. The lamp bead board wires are assembled on the focusable fill light 10, and the wires are clamped by the three buckles 43 and the wire groove, so that the wires are firmly fixed, and isolation ribs are provided to block the wires, so that the normal movement of the rack 44 and the gear is not affected, thereby improving the practicality and user experience of the focusable fill light 10.
[0038] See also Figure 5 and Figure 6The knob 60 includes a transmission part 62, a connection part 63 and a rotating part connected in sequence. The transmission part 62 is located in the housing 20 and is transmission-connected to the lamp body 40, so that the user can adjust the fill light when rotating the knob 60. The connection part 63 is arranged in the housing 20, and the connection part 63 is rotatably clamped on the housing 20 through a retaining spring. An asymmetric slot 631 is provided at one end of the connection part 63 close to the rotating part. The rotating part is provided with an insertion shaft corresponding to the shape of the slot 631. The rotating part is detachably installed in the slot 631 through the insertion shaft, so that the rotating part can be conveniently disassembled. In some embodiments, the focusing distance of the focusable fill light 10 is 12 to 13 mm. Since the stroke of the above-mentioned focusing distance is relatively short, the modulus of the rotating part can be set to 1.0, so that the outer diameter and the tooth shape of the rotating part are relatively small. In this way, the knob 60 only needs to rotate about half a circle to complete the stroke focusing process, so that the focusing of the focusable fill light 10 is faster and quicker. In some embodiments, the material of the rotating part is nylon or polyoxymethylene, which has better self-lubrication and wear resistance, and can improve the wear resistance of the focusable fill light 10. A rack 44 extending in the axial direction is fixed to the lamp body 40, and the end of the knob 60 extending into the interior of the housing 20 has a gear structure 61, and the gear structure 61 is meshed with the rack 44. In some embodiments, the modulus of the rack 44 is small, the outer diameter of the gear is small, and it can withstand a large torque. The focusable fill light 10 uses a gear and a rack 44 to achieve focusing, and a damping member can be added to the knob 60. Due to the soft friction of the damping member being clamped, the knob 60 has a better damping feeling when it is turned. The damping member can make the focusing process more stable and not too sensitive when the user rotates the knob 60 to focus. The knob 60 and the gear damping rotation are connected to the lamp body 40. When in use, the user rotates the knob 60, and the rotation of the knob 60 drives the gear, and then drives the rack 44 to move, thereby achieving a stable focusing process. The focusing process of the lamp body 40 can be made more stable and not too sensitive, thereby improving the user experience.
[0039] See also Figure 1 to Figure 7In some embodiments, the lamp body 40 further includes a bracket 80 and a radiator. The fill light generates a large amount of heat when working. If the heat is not dissipated in time, the light may overheat, affect the life of the lamp beads, or even be damaged. The radiator helps the light maintain a large luminous flux output under high-intensity use and prolongs the service life of the lamp beads by increasing the heat dissipation area and optimizing the heat dissipation design. A good heat dissipation system can ensure that the fill light maintains a stable brightness during long-term use, avoid brightness fluctuations caused by overheating, and thus provide a more stable lighting effect. Specifically, the light-emitting component and the radiator are fixed in the bracket 80, which is conducive to helping the light maintain a large luminous flux output under high-intensity use and prolong the service life of the lamp beads. The knob 60 is connected to the bracket 80 in a transmission manner, and the bracket 80 plays a supporting role. The bracket 80 can be made of metal material, such as aluminum alloy. The aluminum alloy material has high strength and can withstand large external forces. It also has the advantage of light weight, which can not only ensure the stability and durability of the adjustable focus fill light 10, but also be easy to carry and use.
