[0002] Currently, common zoom lights on the market often require the replacement of different lenses during application, such as lenses with different focal lengths or lenses with different light spot styles.

[0003] In related technologies, replacing the lens usually requires disassembling the entire structure of the lamp, which is cumbersome and time-consuming, and often inconvenient. Utility Model Content

[0004] This utility model provides a focusing lamp head and lamp fixture, which can improve the convenience of lens disassembly and assembly.

[0005] This utility model discloses a focusing lamp head, comprising: a support frame and a lens bracket slidably connected to the support frame. The support frame is used for fixed connection with a lamp holder. A focusing ring is also rotatably connected to the support frame. The lens bracket is provided with a spiral groove and an unlocking groove communicating with the spiral groove. A lens is mounted on the lens bracket. The inner ring of the focusing ring is provided with a locking protrusion that cooperates with the spiral groove. When the focusing ring is rotated, the locking protrusion moves relative to the spiral groove to drive the lens bracket to slide relative to the support frame. When the focusing ring is rotated and the lens bracket is pressed, the locking protrusion can slide into the unlocking groove so that the lens bracket can disengage from the support frame.

[0006] Optionally, the support frame includes a positioning ring and a plurality of support portions arranged in a circumferential array on the positioning ring. Adjacent support portions are connected by arc-shaped support ribs. One of the support portions and the lens bracket is provided with a sliding groove, and the other is provided with a sliding rail. The sliding groove and the sliding rail are slidably connected.

[0007] Optionally, the lens holder is located inside the support portion, and the focusing ring is located outside the support portion.

[0008] Optionally, the unlocking groove includes a first connecting segment, a second connecting segment, and a third connecting segment connected in sequence. The unlocking groove is connected to the spiral groove through the first connecting segment, and the extending directions of the first connecting segment and the third connecting segment are consistent with the extending direction of the sliding groove. The second connecting segment is an arc-shaped groove arranged along the axial direction of the lens bracket.

[0009] Optionally, the inner ring of the lens holder is provided with a first annular stepped groove, and the edge of the lens is provided with a mating part, which can be engaged at the first annular stepped groove.

[0010] Optionally, the focusing lamp head further includes a lamp cover for fixed connection with the lamp holder; the inner ring of the lens bracket is also provided with a second annular stepped groove, the diameter of the second annular stepped groove being larger than the diameter of the first annular stepped groove, and the second annular stepped groove being used to limit the position of the lamp cover.

[0011] Optionally, the focusing ring is also provided with a plurality of ventilation slots, which are connected to the lamp cover and are used to dissipate heat from the lamp beads inside the lamp cover.

[0012] Optionally, the focusing lamp head further includes a damping component connected to the support frame. The damping component includes a connecting frame connected to the positioning ring. An elastic top protrusion is formed on the connecting frame. The outer circumference of the focusing ring is provided with a plurality of arc-shaped protrusions. A groove is formed between adjacent arc-shaped protrusions. The arc-shaped protrusions can elastically abut against the grooves.

[0013] Optionally, the outer ring of the focusing ring is also provided with anti-slip texture.

[0014] This utility model also discloses a lamp, including a lamp holder and a focusing lamp head as described in any one of the above claims, wherein the focusing lamp head is connected to the lamp holder.

[0015] The beneficial effects of the focusing lamp head and lamp provided in this embodiment of the utility model are as follows: Through the cooperation of the lens bracket slidably connected to the support frame and the focusing ring rotatably connected to the support frame, the spiral groove on the lens bracket and the unlocking groove communicating with the spiral groove can engage with the locking protrusion of the inner ring of the focusing ring. When focusing is required, simply rotate the focusing ring, and the focusing ring will rotate around the support frame. Due to the cooperation between the locking protrusion and the spiral groove, the rotational motion of the focusing ring will be converted into relative movement of the locking protrusion within the spiral groove, thereby causing the lens bracket to slide relative to the support frame. The sliding of the lens bracket changes the distance between the lens and the lamp bead, thus realizing the focusing function of the lamp and meeting the needs for the degree of light focus in different scenarios. When it is necessary to replace the lens or lamp bead, the user can rotate the focusing ring and simultaneously press the lens bracket to make the locking protrusion of the inner ring of the focusing ring slide from the spiral groove into the unlocking groove. Once the locking protrusion enters the unlocking slot, the limiting relationship between the lens holder, the focusing ring, and the support frame is released. At this point, the lens holder can smoothly detach from the support frame, allowing the user to easily remove it and replace the lens. After replacement, the lens holder with the new lens is reinstalled back into the support frame, allowing the locking protrusion to slide back into the spiral groove, thus restoring the focusing lamp head to normal operation. Using this method, lens replacement does not require disassembling the entire lamp fixture structure. A simple operation of rotating the focusing ring and pressing the lens holder detaches it from the support frame, greatly simplifying the lens replacement process, saving time, improving efficiency, and providing significant convenience for users.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, this utility model embodiment provides a focusing lamp head 100 including: a support frame 110 and a lens bracket 120 slidably connected to the support frame 110. The support frame 110 is used for fixed connection with the lamp holder. A focusing ring 130 is also rotatably connected to the support frame 110. The lens bracket 120 is provided with a spiral groove 122 and an unlocking groove 124 communicating with the spiral groove 122. A lens 140 is mounted on the lens bracket 120. The inner ring of the focusing ring 130 is provided with a locking protrusion 132 that cooperates with the spiral groove 122. When the focusing ring 130 is rotated, the locking protrusion 132 moves relative to the spiral groove 122 to drive the lens bracket 120 to slide relative to the support frame 110. When the focusing ring 130 is rotated and the lens bracket 120 is pressed, the locking protrusion 132 can slide into the unlocking groove 124 so that the lens bracket 120 can be disengaged from the support frame 110.

[0020] Specifically, the support frame 110 serves as the basic support component of the entire focusing lamp head 100, providing a stable mounting base for other components through a stable connection between the support frame 110 and the lamp holder. The lens bracket 120 is slidably connected to the support frame 110, allowing the lens bracket 120 to move smoothly relative to the support frame 110. The lens 140 is mounted on the lens bracket 120, and the movement of the lens bracket 120 directly affects the position of the lens 140, thereby ensuring stable focusing.

[0021] The focusing lamp head 100 provided in this embodiment of the application, through the cooperation of a lens bracket 120 slidably connected to a support frame 110 and a focusing ring 130 rotatably connected to the support frame 110, enables the spiral groove 122 provided on the lens bracket 120 and the unlocking groove 124 communicating with the spiral groove 122 to engage with the locking protrusion 132 on the inner ring of the focusing ring 130. When focusing is required, only the focusing ring 130 needs to be rotated, and the focusing ring 130 will rotate around the support frame 110. Due to the cooperation between the locking protrusion 132 and the spiral groove 122, the rotational motion of the focusing ring 130 will be converted into the relative movement of the locking protrusion 132 within the spiral groove 122, thereby causing the lens bracket 120 to slide relative to the support frame 110. The sliding of the lens bracket 120 will change the distance between the lens 140 and the lamp bead, thereby realizing the focusing function of the lamp and meeting the needs of light focusing degree in different scenarios. When it is necessary to replace the lens 140 or the LED, the user can rotate the focusing ring 130 while simultaneously pressing the lens bracket 120 to slide the locking protrusion 132 of the inner ring of the focusing ring 130 from the spiral groove 122 into the unlocking groove 124. After the locking protrusion 132 enters the unlocking groove 124, the limiting relationship between the lens bracket 120, the focusing ring 130, and the support frame 110 is released. At this time, the lens bracket 120 can be smoothly disengaged from the support frame 110, and the user can easily remove the lens bracket 120 and replace the new lens 140. After the replacement is completed, the lens bracket 120 with the new lens 140 is installed back into the support frame 110, and the locking protrusion 132 slides back into the spiral groove 122, thus restoring the normal use of the focusing lamp head 100. Using the above method, when replacing the lens 140, there is no need to disassemble the entire lamp structure. The lens bracket 120 can be detached from the support frame 110 simply by rotating the focusing ring 130 and pressing the lens bracket 120. This greatly simplifies the lens 140 replacement process, saves replacement time, improves the efficiency of lens 140 replacement, and brings great convenience to users.

[0022] like Figure 3 and Figure 4 As shown, the support frame 110 includes a positioning ring 112 and a plurality of support parts 114 arranged in a circumferential array on the positioning ring 112. Adjacent support parts 114 are connected by arc-shaped support ribs 116. One of the support parts 114 and the lens bracket 120 is provided with a sliding groove 126, and the other is provided with a sliding rail 118. The sliding groove 126 and the sliding rail 118 are slidably connected.

[0023] Specifically, the positioning ring 112 has a ring structure, serving for positioning and connection, allowing the support frame 110 to connect to the lamp holder via the positioning ring 112. Multiple support parts 114 are arranged in a circular array on the positioning ring 112, providing stable and uniform support for the lens bracket 120. Adjacent support parts 114 are connected by arc-shaped support ribs 116, which enhance the connection strength between the support parts 114, improve the overall structural stability and rigidity of the support frame 110, and prevent deformation of the support frame 110 under stress during use. Furthermore, the sliding connection between the slide groove 126 and the slide rail 118 provides precise guidance and stable fit for the sliding of the lens bracket 120 relative to the support frame 110. This connection effectively reduces frictional resistance during the sliding process of the lens bracket 120, making the sliding smoother, avoiding jamming, ensuring smooth focusing operations, and improving the user's operating experience.

[0024] In an optional embodiment of this application, the lens holder 120 is located inside the support portion 114, and the focusing ring 130 is located outside the support portion 114.

[0025] Specifically, the lens holder 120 is located inside the support portion 114, which allows it to better align with the lamp beads and other components inside the lamp, facilitating the lens 140 to receive, refract, and focus the light emitted by the lamp beads. Simultaneously, the inner position also provides some protection for the lens holder 120, reducing interference and damage to the lens holder 120 and lens 140 from external factors. The focusing ring 130 is located outside the support portion 114. Focusing can be achieved simply by contacting the focusing ring 130 outside the lamp and rotating it, conforming to ergonomic design and improving user convenience.

[0026] like Figure 5 As shown, the unlocking groove 124 includes a first connecting section 1242, a second connecting section 1244, and a third connecting section 1246 connected in sequence. The unlocking groove 124 is connected to the spiral groove 122 through the first connecting section 1242, and the extending directions of the first connecting section 1242 and the third connecting section 1246 are consistent with the extending direction of the slide groove 126. The second connecting section 1244 is an arc-shaped groove arranged along the axial direction of the lens bracket 120.

[0027] Specifically, the design of the first connecting section 1242 and the third connecting section 1246 extending in the same direction as the slide groove 126 allows the locking protrusion 132 to better match the sliding direction of the lens bracket 120 when entering and leaving the unlocking groove 124, reducing resistance and jamming during movement and ensuring smooth operation. Under normal conditions, the locking protrusion 132 is located within the spiral groove 122. When the focusing ring 130 is rotated, the rotation of the focusing ring 130 presses against the lens bracket 120, causing the lens bracket 120 to exert a force in the direction of the locking protrusion 132. This causes the locking protrusion 132 to move to the interface between the first connecting section 1242 and the spiral groove 122, allowing it to slide into the first connecting section 1242 and then slide to the connection point between the first connecting section 1242 and the second connecting section 1244. At this point, the focusing ring 130 can be rotated clockwise to move the locking protrusion 132 along the second connecting section 1244 to the position of the third connecting section 1246. In practical applications, the lamp is generally installed upside down on top. In this case, the lens bracket 120 can slide out of the support frame 110 under its own weight, thus enabling the lens bracket 120 to be disassembled. This facilitates the replacement of the lens 140 and the cleaning of dust and other debris inside the lamp, as well as the replacement of the LED chips.

[0028] Understandably, when it is necessary to install the lens holder 120, it is only necessary to align the locking protrusion 132 with the third connecting section 1246 and align the slide groove 126 with the slide rail 118. This allows the locking protrusion 132 to slide along the third connecting section 1246 to the connection point between the third connecting section and the second connecting section 1244. At this time, rotating the focusing ring 130 counterclockwise allows the locking protrusion 132 to slide along the second connecting section 1244 to the connection point between the second connecting sections 1244 and the second connecting section 1244. This allows the lens holder 120 to be installed by its own weight, causing the locking protrusion 132 to slide into the spiral groove 122.

[0029] It should be noted that each corresponding unlocking slot 124 and spiral groove 122 is set in a group, and a group of unlocking slots 124 and spiral grooves 122 corresponds to a card protrusion 132. In practical applications, the card protrusion 132 can be set to 2, 3 or 4. Similarly, the unlocking slots 124 and spiral grooves 122 can be set to 2, 3 or 4 groups.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the inner ring of the lens holder 120 is provided with a first annular stepped groove 127, and the edge of the lens 140 is provided with a docking part 142, which can be engaged at the first annular stepped groove 127.

[0031] Specifically, when installing the lens 140, simply align the mating portion 142 of the lens 140 edge with the first annular stepped groove 127 of the inner ring of the lens bracket 120, and hold the mating portion 142 in the first annular stepped groove 127. In order to ensure the stable installation of the lens bracket 120 and the lens 140, glue can be applied to the first annular stepped groove 127 and the mating portion 142 so that the two can be bonded and fixed, and the lens 140 can be prevented from accidentally falling off.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown, the focusing lamp head 100 also includes a lamp cover 150, which is used to fix and connect with the lamp holder; the inner ring of the lens bracket 120 is also provided with a second annular stepped groove 128, the diameter of the second annular stepped groove 128 is larger than the diameter of the first annular stepped groove 127, and the second annular stepped groove 128 is used to limit the lamp cover 150.

[0033] Specifically, the main function of the second annular stepped groove 128 is to limit the movement distance of the lens bracket 120 through the lamp cover 150. When the lamp cover 150 is installed on the lamp holder, one end of the lamp cover 150 will contact the second annular stepped groove 128 on the inner ring of the lens bracket 120, preventing the lens 140 from getting too close to the lamp chip when the lens bracket 120 moves with the lens 140, thus protecting both the lens 140 and the lamp chip. In addition, the diameter of the second annular stepped groove 128 is larger than the diameter of the first annular stepped groove 127, which ensures the proper loading of the lens 140.

[0034] like Figure 3 As shown, the focusing ring 130 is also provided with a plurality of ventilation slots 134, which are connected to the lamp cover 150 and are used to dissipate heat from the lamp beads inside the lamp cover 150.

[0035] Specifically, the ventilation slots 134 are connected to the lamp cover 150, which effectively promotes airflow at the location of the LED beads, thereby dissipating the heat generated by the LED beads inside the lamp cover 150 to the external environment in a timely manner. This reduces the internal temperature of the lamp cover 150 and prevents the LED beads from experiencing performance degradation, shortened lifespan, or even burnout due to prolonged exposure to high temperatures. Multiple ventilation slots 134 are provided, typically arranged in a circumferential array on the focusing ring 130, ensuring that air enters and exits the lamp cover 150 evenly from multiple directions, resulting in more uniform and efficient heat dissipation and preventing localized insufficient heat dissipation.

[0036] like Figure 3 and Figure 6As shown, the focusing lamp head 100 also includes a damping member 160 connected to the support frame 110. The damping member 160 includes a connecting frame 162 connected to the positioning ring 112. An elastic top protrusion is formed on the connecting frame 162. The outer circumference of the focusing ring 130 is provided with a plurality of arc-shaped protrusions 136. A groove 1362 is formed between adjacent arc-shaped protrusions 136. The arc-shaped protrusions can elastically abut against the groove 1362.

[0037] Specifically, an elastic protrusion is formed on the connecting frame 162. The elastic protrusion has a certain deformation capability and rebound force, and can undergo elastic deformation when subjected to pressure, and return to its original shape after the pressure is released (it can be the deformation of its own body or the deformation of the connecting frame 162). When the focusing ring 130 is in a stationary state, the elastic protrusion can elastically resist within a groove 1362 under its own elastic force, forming a stable limiting fit. When the user rotates the focusing ring 130, the arc-shaped protrusion 136 of the focusing ring 130 will squeeze the elastic top protrusion, causing the elastic top protrusion to deform elastically and disengage from the current groove 1362. As the focusing ring 130 continues to rotate, the elastic top protrusion will spring back into the next groove 1362 after passing the arc-shaped protrusion 136, making the rotation process of the focusing ring 130 have a distinct sense of segmentation. The user can perceive the change in the focusing position by touch or a slight sound. At the same time, the cooperation between the elastic top protrusion and the groove 1362 also provides a stable damping force for the focusing ring 130, preventing the focusing ring 130 from shifting when not in operation.

[0038] like Figure 3 As shown, the outer ring of the focusing ring 130 is also provided with anti-slip texture 138.

[0039] Specifically, the anti-slip texture 138 refers to the texture structure formed on the outer surface of the focusing ring 130 that increases friction. Common textures include longitudinal stripes, transverse stripes, grid patterns, wave patterns, or diamond patterns. The specific texture can be selected according to the product appearance design and anti-slip requirements.

[0040] This utility model also discloses a lamp fixture, including a lamp holder and a focusing lamp head 100 as described in the foregoing embodiments, the focusing lamp head 100 being connected to the lamp holder. This lamp fixture includes the same structure and beneficial effects as the focusing lamp head 100 in the foregoing embodiments. The structure and beneficial effects of the focusing lamp head 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0041] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
