[0036] A macro fill light is a lighting device specifically designed for close-up photography. Its core function is to provide ample, controllable, and shadow-free light to the very close area of the subject, solving the problems of insufficient natural light and excessively strong or harsh ordinary flashes in macro photography.
[0037] Existing macro fill lights are usually fixed structures without the function of adjusting the focus, making the lighting setup inflexible.
[0038] This application discloses a lamp head assembly 100, which is applied to a macro fill light 1000, as shown in the reference. Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the lamp holder assembly 100 in one embodiment of this application. Figure 2 This is a schematic diagram of the structure of another embodiment of the lamp holder assembly 100 of this application; Figure 3 This is a cross-sectional schematic diagram of the lamp holder assembly 100 in another embodiment of this application. Figure 4 This is a cross-sectional schematic diagram of the lamp holder assembly 100 in another embodiment of this application. Figure 5 This is a schematic diagram of the structure of the movable member 130 in the lamp holder assembly 100 according to one embodiment of the present application. In some embodiments, the lamp holder assembly 100 includes a housing 110, a focusing member 120, a movable member 130, and a light-emitting member 140. The housing 110 has a receiving cavity with openings at both ends. The focusing member 120 is disposed at the edge of one opening of the housing 110. One end of the movable member 130 is movably inserted into the receiving cavity along the axial direction of the receiving cavity, and the other end of the movable member 130 is partially exposed in another opening. The light-emitting member 140 is disposed on the end face of the movable member 130 near the end of the focusing member 120.
[0039] In this embodiment, the outer shell 110 is a basic component of the lamp head assembly 100, providing a mounting position for the subsequent focusing element 120 and a track for the sliding of the movable element 130. It also protects other internal components of the lamp head assembly 100. The outer shell 110 is a sleeve structure with an internal cavity that is open at both ends and extends through it. One end of the opening is used to install the focusing element 120, and the other end allows the movable element 130 to pass through, enabling it to slide relative to the outer shell 110. The outer shell 110 is made of hard plastic or lightweight metal, such as aluminum alloy, making it sturdy and durable, and able to protect internal components such as the light-emitting element 140 to a certain extent. It is understood that, in another embodiment, the outer casing 110 can be configured as separate parts, including a cover and a barrel. The cover and the barrel are detachably connected by a threaded connection or a snap-fit connection. The edge of the focusing element 120 is sandwiched between the cover and the barrel. When the cover and the barrel are connected, the focusing element 120 is clamped between them, thus achieving both the connection between the cover and the barrel and the fixation of the focusing element 120. In a preferred embodiment, a sealing element is provided between the focusing element 120 and the outer casing 110, specifically a sealing ring or sealing strip, etc. The sealing element can seal the gap between the focusing element 120 and the outer casing 110, preventing water from entering the lamp head assembly 100 and improving the sealing performance of the lamp head assembly 100.
[0040] The focusing element 120 is an optical lens, which can be either a concave or convex lens. The concave lens disperses the light, while the convex lens converges the light. The specific lens used can be flexibly selected according to the application scenario of the lamp head assembly 100. The connection between the focusing element 120 and the housing 110 can be achieved by adhesive bonding, snap-fit bonding, or by both parts of the housing 110 clamping the focusing element 120 together. No further limitation is made here.
[0041] The movable component 130 is a moving part within the lamp head assembly 100, serving to move the light-emitting component 140. Specifically, the movable component 130 can be a columnar structure, with one end inserted into the outer casing 110 and the other end partially exposed outside another opening in the outer casing 110. Driving the other end of the movable component 130 allows it to slide relative to the outer casing 110, thereby changing the distance between one end of the movable component 130 and the opening in the outer casing 110. The movable component 130 can be made of rigid plastic, which has self-lubricating properties, reducing sliding resistance between the movable component 130 and the outer casing 110, making the sliding smoother. Alternatively, it can be made of materials such as rubber, with an interference fit between it and the outer casing 110 to achieve sliding and stepless hovering. In a preferred embodiment, the movable component 130 has a hollow structure, which reduces overall weight, saves production costs, and also helps dissipate heat from the light-emitting component 140.
[0042] The light-emitting component 140 is a part within the lamp head assembly 100 that emits a light source. Specifically, the light-emitting component 140 can be an LED bead or a light-emitting part equivalent to an LED bead. The light-emitting component 140 is connected to one end face of the movable component 130. Movement of the movable component 130 relative to the housing 110 causes the light-emitting component 140 to move relative to the housing 110. By changing the distance between the light-emitting component 140 and the focusing component 120, the focal length is adjusted, thereby adjusting the projection range and intensity of the light. This allows the light-emitting mode of the lamp head assembly 100 to adapt to different application scenarios, making it more flexible in use. The connection between the light-emitting component 140 and one end face of the movable component 130 can be achieved using screw connections or adhesive connections, etc., without further limitation. In a preferred embodiment, the lamp head assembly 100 further includes a reflector, which is disposed on the outer periphery of the light-emitting element 140. The reflective portion of the reflector is funnel-shaped. When the light emitted by the light-emitting element 140 shines on the reflective portion of the reflector, it can be reflected, thereby concentrating the light and improving the brightness of the lamp head assembly 100.
[0043] When using the lamp head assembly 100, the user can manually drive the movable part 130 or the housing 110 to make the movable part 130 and the housing 110 slide relative to each other, changing the distance between the light-emitting element 140 on the movable part 130 and the focusing element 120 on the housing 110, thereby adjusting the focal length, that is, adjusting the projection range and light intensity of the light, so that the light emission mode of the lamp head assembly 100 can be adapted to different application scenarios and used more flexibly.
[0044] The lamp head assembly 100 proposed in this application includes a housing 110, a focusing element 120, a movable element 130, and a light-emitting element 140. The housing 110 has a receiving cavity with openings at both ends. The focusing element 120 is disposed in one of the openings. The light-emitting element 140 is disposed on one end face of the movable element 130, and one end of the movable element 130 is movable relative to the housing 110. The other end of the movable element 130 is exposed in another opening of the housing 110. Driving the movable element 130 or driving the housing 110 causes the movable element 130 to move the light-emitting element 140 in the axial direction relative to the housing 110. By changing the distance between the light-emitting element 140 and the focusing element 120, the focal length of the light can be adjusted, and the projection range and intensity of the light can be adjusted so that the light emission mode of the lamp head assembly 100 can be adapted to different application scenarios, making it more flexible in use.
[0045] In some embodiments, refer to Figure 3 and Figure 4 The outer peripheral wall of the movable part 130 is provided with a protrusion 131, and another opening of the receiving cavity is provided with a boss 111 extending circumferentially thereon. The protrusion 131 is movably disposed between the boss 111 and an opening.
[0046] In this embodiment, the protrusion 131 is a protruding structure protruding from the outer peripheral wall of the movable member 130, and the protrusion 131 and the movable member 130 are integrally formed by injection molding. The protrusion 131 cooperates with the boss 111, which is provided at another opening of the receiving cavity. When the protrusion 131 slides to the other opening of the receiving cavity, the protrusion 131 abuts against the boss 111, thereby preventing the movable member 130 from detaching from the receiving cavity of the outer shell 110. At least one of the protrusion 131 and the boss 111 extends along the circumferential direction of the outer shell 110, and can abut against the protrusion 131 in the entire circumferential direction to prevent the movable member 130 from falling out of the outer shell 110. The difference between the axial length of the protrusion 131 and the axial length of the cavity inside the housing 110 is the range of movement of the movable part 130, which is the range of focal length adjustment of the lamp head assembly 100. The specific axial length of the protrusion 131 can be selected according to the actual needs of focal length adjustment, and is not further limited here.
[0047] In some embodiments, refer to Figures 3 to 5The protrusion 131 has a groove 1311 extending along the circumferential direction of the protrusion 131. A silicone part 1312 is provided in the groove 1311, and part of the silicone part 1312 is exposed in the groove opening of the groove 1311 to make an interference fit with the cavity wall of the receiving cavity.
[0048] In this embodiment, the groove 1311 extends circumferentially along the protrusion 131. A silicone element 1312 is disposed within the groove 1311. The silicone element 1312 can be a silicone ring, with the silicone ring portion exposed at the opening of the groove 1311. When the movable member 130 passes through the outer shell 110, the silicone element 1312 is pressed between the cavity wall of the receiving cavity and the bottom of the groove 1311. When the movable member 130 slides relative to the outer shell 110, friction is generated between the silicone element 1312 and the inner wall of the receiving cavity. When the movable member 130 loses external force, the friction between the silicone element 1312 and the inner wall of the receiving cavity prevents the movable member 130 from continuing to move, achieving the effect of stepless hovering of the movable member 130 relative to the outer shell 110.
[0049] In some embodiments, refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of a movable part in the lamp head assembly of this application. There are two grooves 1311 in each case. The two grooves 1311 are spaced apart along the axial direction of the protrusion 131. A silicone part 1312 is provided in one groove 1311.
[0050] In this embodiment, two grooves 1311 are formed on the outer peripheral wall of the protrusion 131. A silicone element 1312 is disposed in one groove 1311. When the movable part 130 slides relative to the outer shell 110, both silicone elements 1312 abut against the inner wall of the receiving cavity, generating friction, which increases the force on the movable part 130, improves the connection strength between the movable part 130 and the outer shell 110, and prevents the movable part 130 from continuing to move, thus achieving the effect of the movable part 130 being able to hover steplessly relative to the outer shell 110. Two grooves 1311 are spaced apart along the axial direction of the protrusion 131, and both grooves 1311 are arranged around the circumferential direction of the movable member 130. Correspondingly, the silicone part 1312 in the groove 1311 is also arranged around the circumferential direction of the movable member 130, so that the force between the silicone part 1312 and the inner wall of the outer shell 110 is more uniform in the circumferential direction, and the force on the movable member 130 in both the axial and circumferential directions is more uniform, preventing the movable member 130 from tilting, which would cause the light emission direction of the light-emitting element 140 to tilt and affect the lighting supplement effect.
[0051] In some embodiments, refer again Figure 5The protrusion 131 is also provided with an exhaust groove 1313, which extends through the axial direction of the protrusion 131 so that the two receiving cavities separated by the silicone part 1312 are connected.
[0052] In this embodiment, the exhaust groove 1313 is a groove-shaped structure that extends through the axial direction of the protrusion 131, serving to connect the receiving cavity above the movable member 130 with the receiving cavity below the movable member 130. This prevents the sealing between the silicone part 1312 and the inner wall of the receiving cavity from creating a vacuum compression in the receiving cavity above the movable member 130, which could cause the outer shell 110 or the focusing part 120 to crack. It is understood that, in a preferred embodiment, there are multiple exhaust grooves 1313, which are evenly distributed along the circumferential direction of the protrusion 131 to increase the exhaust speed and prevent a vacuum compression in the receiving cavity above the movable member 130.
[0053] In some embodiments, such as Figure 5 As shown, the other end of the movable member 130 is provided with a limiting part 132, which extends outward along the radial direction of the movable member 130.
[0054] In this embodiment, the limiting part 132 is a limiting structure disposed at the other end of the movable part 130. Specifically, it is a structure that extends radially outward along the other end of the movable part 130, thereby limiting the movement distance of the movable part 130 into the outer shell 110 and preventing the light-emitting element 140 on one end of the movable part 130 from colliding with the light-concentrating element 120, which could cause damage to the light-emitting element 140 or the light-concentrating element 120. The limiting part 132 can be made of rigid plastic or lightweight metal, and no further limitation is made here. The connection between the limiting part 132 and the other end of the movable part 130 can be made by threaded connection, snap-fit connection, or adhesive connection, etc. It is understood that the limiting part 132 and the other end of the movable part 130 can also be integrally formed by injection molding.
[0055] This application further proposes a macro fill light 1000, with reference to... Figures 6 to 8 , Figure 6 This is a schematic diagram of the structure of an embodiment of the macro fill light of this application. Figure 7 This is a schematic diagram of another embodiment of the macro fill light of this application. Figure 8 for Figure 7 The cross-sectional view at point AA shows that the macro fill light 1000 includes a lamp head assembly 100, a connecting assembly 200, and a handle 300. The lamp head assembly 100 is the lamp head assembly 100 as described above. One end of the connecting assembly 200 is connected to the movable part 130 of the lamp head assembly 100. The handle 300 is connected to the other end of the connecting assembly 200.
[0056] In this embodiment, the lamp head assembly 100 is the same as the lamp head assembly 100 in the above embodiments. The connecting component 200 is a connection structure disposed between the lamp head assembly 100 and the handle 300, which extends the lamp head assembly 100, making the macro fill light 1000 applicable to more application scenarios. The connecting component 200 can be a rod, with both ends connected to the lamp head assembly 100 and the handle 300 respectively. The specific connection method can be a detachable connection, such as a threaded connection, a snap-fit connection, or a plug-in connection, to facilitate disassembly or replacement of various components. It is understood that, in a preferred embodiment, the rod can be a telescopic rod, so that the lamp head assembly 100 can extend a greater distance. The handle 300 is the grip structure for the macro fill light 1000. The user holds the macro fill light 1000 through the handle 300 to illuminate or supplement the light on the object being photographed.
[0057] In some embodiments, the connecting component 200 is a snake tube.
[0058] In this embodiment, the snake tube is a metal flexible tube with high strength, flexible positioning, and no rebound. It is mainly made of steel wire, copper wire, or iron wire, and the surface can be treated with chrome plating, nickel plating, etc. to prevent rusting. One end of the snake tube is connected to the lamp head assembly 100, and the other end is connected to the handle 300. Due to the flexible nature of the snake tube, the extension direction of the lamp head assembly 100 and the extension direction of the handle 300 can form any angle, which can realize the free adjustment of the illumination direction of the light, expand the illumination angle and range of the macro supplementary light 1000, and improve the flexibility of use. In a preferred embodiment, the snake tube has a hollow structure, through which a power supply wire passes, connecting the light-emitting element 140 in the lamp head assembly 100 and the PCB board or battery in the handle 300.
[0059] In some embodiments, refer to Figure 6 and Figure 8 The handle 300 is equipped with a power supply component 310, which is electrically connected to the light-emitting component 140.
[0060] And / or, the end face of the handle 300 facing away from the connecting assembly 200 is provided with a connecting hole 320.
[0061] In this embodiment, the power supply component 310 is a component that provides power to the light-emitting component 140 inside the handle 300. Specifically, it can be a secondary battery or a dry cell battery, and is electrically connected to the light-emitting component 140 inside the lamp head assembly 100 through an electrical wire passing through the connecting assembly 200.
[0062] In one example, the connection hole 320 is a connection structure located on the bottom end face of the handle 300. It is used to install other accessories or to connect the macro fill light 1000 to the photography equipment through the connection hole 320, eliminating the need for manual handling and improving the user experience. The connection hole 320 is specifically a common 1 / 4-20UNC nut structure, facilitating the installation of other accessories.
[0063] In a preferred embodiment, the handle 300 also includes a PCB board, a charging interface, and buttons. The PCB board is located inside the handle 300 and is electrically connected to the power supply component 310 and the light-emitting component 140. The power supply component 310 supplies power to the light-emitting component 140 through the PCB board and can control the light-emitting mode and intensity of the light-emitting component 140. One end of the charging interface is electrically connected to the PCB board, while the other end is exposed on the outer shell 110 of the handle 300, allowing connection to an external power source to power the PCB board and / or charge the power supply component 310. One side of the button is electrically connected to the PCB board, while the other side is exposed outside the handle 300, facilitating user access to press the button. The button allows switching between light-emitting modes or light-emitting intensities, improving the flexibility of the macro fill light 1000.
[0064] In a preferred embodiment, the outer wall of the handle 300 is provided with an anti-slip rubber sleeve or anti-slip pattern to prevent the user from slipping when holding and using the macro fill light 1000, so as not to affect the shooting effect.
[0065] In some embodiments, refer to Figure 6 The macro fill light 1000 also includes a light control component 400, which is detachably connected to the lamp head assembly 100.
[0066] In this embodiment, the light control component 400 is a component that uses optical principles to regulate light. It is typically installed on the light-emitting side of the lamp head assembly 100, allowing the light generated by the light-emitting element 140 within the lamp head assembly 100 to be controlled by the light control component 400 to achieve different lighting effects. The light control component 400 includes, but is not limited to, a spool, a light shield, and a diffuser. A spool is an optical accessory used in photographic or film lighting. Its core function is to converge and precisely project light onto a small, clearly defined area, while the light emitted by the light source is divergent. After entering the spool, the light is refracted by a Fresnel lens, and a large amount of light is "constrained" and adjusted into parallel or near-parallel beams, thereby achieving the effects of convergence and long-distance projection. A light shield is an accessory installed on the lamp head assembly 100. Its main function is to precisely control the direction of light propagation and the illumination range through physical blocking, further enhancing the flexibility of lighting setup. A diffuser is an accessory installed in front of the light-emitting element 140 inside the light head assembly 100. Its core function is to expand the relative light-emitting area of the light source and disperse the light through diffuse reflection materials, thereby transforming harsh and strong direct light into soft and uniform light, further enhancing the flexibility of lighting setup.
[0067] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
