[0002] Current lighting products on the market suffer from significant design flaws, with all lamp heads featuring a fixed, non-rotatable structure. This design introduces numerous drawbacks in practical use. For instance, when users need to change the direction of illumination, the lamp head cannot rotate independently; the entire head must be moved. This is extremely inconvenient in environments requiring high operational efficiency and precision, such as medical settings and educational settings. For example, medical staff need to frequently adjust the lighting during surgery or examinations, and the fixed lamp head design consumes more time and effort, severely impacting workflow. Furthermore, this inconvenient operation can distract medical staff, disrupt their work rhythm, reduce efficiency, and may even have a potential adverse impact on the quality of medical care. Therefore, there is an urgent need for a lighting product that solves the problem of fixed lamp heads, improving ease of use and enhancing the work efficiency of medical staff and other users.

[0032] Reference Figures 1 to 3 According to an embodiment of the present invention, a lamp holder 32 angle-adjustable lamp fixture includes a lamp base assembly 10, a lamp arm assembly 20, and a lamp head assembly 30. One end of the lamp arm assembly 20 is disposed on the lamp base assembly 10; the lamp head assembly 30 is rotatably disposed on the other end of the lamp arm assembly 20. The lamp head assembly 30 includes a connecting seat 31 and a lamp head 32. One end of the connecting seat 31 is rotatably connected to the lamp arm assembly 20, and one end of the lamp head 32 is rotatably disposed on the other end of the connecting seat 31. The lamp head 32 has a lamp body 321, which is electrically connected to the outside world and is used to emit light.

[0033] The adjustable lamp head 32 lamp fixture according to the present invention has at least the following beneficial effects: Compared with similar products on the market where the lamp head 32 is fixed and cannot be rotated, the adjustable lamp head 32 lamp fixture has significant advantages. In actual use, when it is necessary to adjust the direction of illumination, there is no need to adjust the position of the entire lamp head 32 as with traditional lamp fixtures. Since the lamp head assembly 30 is rotatably disposed at the other end of the lamp arm assembly 20, and one end of the lamp head 32 is rotatably disposed at the other end of the connecting seat 31, this double rotatable structure allows users to conveniently and quickly adjust the angle of the lamp head 32 in multiple dimensions. For example, in medical scenarios, medical staff can quickly and accurately adjust the light emission direction of the lamp head 32 according to different surgical sites or examination areas, greatly improving the convenience of operation and work efficiency, avoiding distraction due to inconvenient operation, and thus ensuring the smooth progress of medical work. At the same time, this design reduces the mechanical stress and wear caused to various parts of the lamp fixture by frequent movement of the entire lamp head 32, effectively extending the service life of the lamp fixture, reducing the cost of use, and bringing users a better user experience and economic benefits.

[0034] The following is in conjunction with the appendix Figures 1 to 3This document provides a detailed description of the lamp with an adjustable lamp head angle of 32. The lamp with an adjustable lamp head angle of 32 in this embodiment mainly includes a lamp holder, a lamp arm assembly 20, and a lamp head assembly 30. The lamp holder, as the basic support part of the entire lamp, is made of sturdy and durable plastic material to ensure the stability of the lamp when placed on a table and prevent it from tipping over due to accidental collisions. One end of the lamp arm assembly 20 is fixed to the lamp holder by bolts or by snap-fit. The lamp arm assembly 20 consists of two or more cantilever segments 21. By rotating the rotation joint 22 between the cantilever segments 21, the angle between the cantilever segments 21, the angle between the lamp head assembly 30 and the lamp arm assembly 20, or the angle between the lamp holder assembly 10 and the lamp arm assembly 20 can be easily changed to meet the needs of the lamp in different usage scenarios. The lamp head assembly 30 is rotatably mounted on the other end of the lamp arm assembly 20. The lamp head assembly 30 includes a connecting seat 31 and a lamp head 32. The connector 31 is made of high-strength aluminum alloy. One end is rotatably connected to the lamp arm assembly 20 via a ball joint or the rotary joint 22 in this invention. The ball joint design allows the connector 31 to rotate freely within a 360-degree range, facilitating initial adjustment of the approximate direction of the lamp head 32. One end of the lamp head 32 is rotatably mounted on the other end of the connector 31 via a rotating shaft made of stainless steel, providing excellent wear resistance and stability. The lamp head 32 can rotate 360 ​​degrees around the shaft, enabling fine adjustment of its light emission direction. The lamp head 32 has a lamp body 321, which uses an LED light source and is connected to an external power source via wires, providing a stable power supply. LED light sources offer advantages such as energy saving, environmental friendliness, and long lifespan, emitting bright and uniform light to meet lighting needs in various environments.

[0035] In practical use, the user first adjusts the angle of the lamp arm assembly 20 according to the height requirements of the usage scenario to achieve a suitable position. Then, by rotating the connecting base 31, the direction of the lamp head 32 is roughly determined. Finally, by rotating the lamp head 32, the angle of the lamp head 32 is precisely adjusted so that the light accurately illuminates the target area. For example, in a hospital operating room, medical staff can quickly adjust the angle of the lamp head 32 according to changes in the surgical site to provide sufficient lighting for the surgery and ensure its smooth progress.

[0036] Furthermore, in some embodiments of this utility model, reference is made to... Figures 1 to 3The lamp holder assembly 30 also includes a lamp cover 322, which has a connection hole 3221. The other end of the connecting seat 31 is rotatably disposed in the connection hole 3221. The inner wall of the connection hole 3221 is provided with a protrusion 3222, which is circumferentially disposed along the inner wall of the connection hole 3221. The lower part of the other end of the connecting seat 31 has an annular groove 3121, in which the protrusion 3222 can be accommodated and rotated.

[0037] In this embodiment, the lamp holder assembly 30 is further provided with a lamp cover 322. A connecting hole 3221 is provided at the top center of the lamp cover 322. The diameter of the connecting hole 3221 is designed according to the size of the connecting seat 31 to ensure that the connecting seat 31 can be smoothly assembled with the lamp cover 322. The inner wall of the connecting hole 3221 is integrally formed with a protrusion 3222 by injection molding. The protrusion 3222 is evenly arranged circumferentially along the inner wall of the connecting hole 3221 to form a continuous annular structure. The other end of the connecting seat 31 is a cylindrical structure with an annular groove 3121 at its lower part. The depth of the groove 3121 is adapted to the shape of the protrusion 3222 on the inner wall of the connecting hole 3221 of the lamp cover 322. During assembly, the other end of the connecting seat 31 is inserted into the connecting hole 3221 of the lamp cover 322, so that the protrusion 3222 on the inner wall of the connecting hole 3221 can be accurately accommodated in the groove 3121 at the lower part of the other end of the connecting seat 31. Because the protrusion 3222 can rotate within the groove 3121, when the user needs to adjust the angle of the lamp head 32, the lampshade 322 can rotate together with the connecting seat 31. Simultaneously, this mating structure of the protrusion 3222 and the groove 3121 also serves to limit and stabilize the lampshade 322, preventing it from falling off or shaking during rotation, thus ensuring the stability and reliability of the lamp during use. For example, when it is necessary to change the illumination range, the user only needs to gently rotate the lamp head assembly 30, and the lampshade 322 will rotate smoothly with the connecting seat 31, thereby achieving flexible adjustment of the light illumination direction to meet the lighting needs of different scenarios.

[0038] Furthermore, in some embodiments of this utility model, reference is made to... Figures 2 to 3The connecting base 31 includes a first adapter block 311 and a second adapter block 312. The first adapter block 311 and the second adapter block 312 are detachably connected. The first adapter block 311 is rotatably connected to the lamp arm assembly 20, and the second adapter block 312 is rotatably connected to the lamp head assembly 30. Both the first adapter block 311 and the second adapter block 312 are made of high-strength and lightweight aluminum alloy or plastic. This material ensures that the connecting base 31 has sufficient structural strength to stably support the lamp head assembly 30, while also reducing the overall weight of the lamp, making it easy to install and move. On one side of the first adapter block 311, a ball joint connection structure adapted to the lamp arm assembly 20 can be provided. This ball joint connection structure allows the first adapter block 311 to be flexibly rotatably connected to the lamp arm assembly 20, with a rotation range of up to 360 degrees, which is convenient for users to initially adjust the approximate direction of the lamp head assembly 30. Alternatively, the lamp arm assembly 20 can be connected via the rotating joint 22 of this embodiment. The lower part of the lower end of the second adapter block 312 is provided with a sliding groove 3121 connection structure that matches the lamp head assembly 30. Through the sliding groove 3121 connection structure, the lamp head assembly 30 can rotate 360 ​​degrees in the groove of the sliding groove 3121 around the axis of the connecting hole 3221 via the protrusion 3222, thereby realizing fine adjustment of the light emission direction of the lamp head 32.

[0039] The first adapter block 311 and the second adapter block 312 are detachably connected. Specifically, two cylindrical positioning pins (not shown in the figure) are provided on the side of the first adapter block 311 connecting to the second adapter block 312. Two positioning holes (not shown in the figure) are provided at corresponding positions on the second adapter block 312. The diameter of the positioning holes matches the positioning pins, and the depth matches the height of the positioning pins. Additionally, four bolt holes (not shown in the figure) are provided at the edges of the first adapter block 311 and the second adapter block 312, which are securely connected together using four stainless steel bolts and nuts. This detachable connection design makes the assembly, maintenance, and repair of the lamp more convenient. For example, when the lamp head assembly 30 malfunctions and needs replacement or repair, simply loosen the bolts and nuts, remove the second adapter block 312 from the first adapter block 311, and the lamp head assembly 30 can be easily operated, greatly improving maintenance efficiency and reducing maintenance costs. During assembly, the locating pin is first inserted into the locating hole for initial positioning, and then the two are tightened with bolts and nuts to ensure that the overall structure of the connecting seat 31 is stable and reliable.

[0040] Alternatively, the first adapter block 311 and the second adapter block 312 can be connected respectively via a threaded connector (not shown in the figure); for example, specifically, the upper end of the second adapter block 312 can be connected via a threaded connector (not shown in the figure), and then by tightening the second adapter block 312, the lower end of the first adapter block 311 can be clamped in the threaded connector, thereby achieving a detachable threaded connection. In summary, it can be understood that the detachable connection method between the first adapter block 311 and the second adapter block 312 is not specifically limited.

[0041] Reference Figures 2 to 3 In some embodiments of this utility model, an electrical connector 40 is provided inside the connector 31. The electrical connector 40 includes a socket 41 and a plug 42. Both the plug 42 and the socket 41 are disposed in the connector 31. The plug 42 is inserted into the socket 41. The socket 41 is fixed relative to the connector 31. A circuit board 323 is provided inside the lampshade 322. The circuit board 323 is electrically connected to the lamp body 321. The connection contact point on the circuit board 323 contacts and abuts against the lower end of the socket 41.

[0042] In this embodiment, the connector 31 incorporates an internal electrical connection design. The connector 31 is made of a plastic material with good insulation properties and is integrally molded using injection molding to ensure the safety of the internal electrical connection. An electrical connector 40 is installed inside the connector 31, consisting of a socket 41 and a plug 42. The socket 41 is made of copper, possessing good conductivity and wear resistance. It is rectangular in shape and is fixedly installed inside the connector 31 near the lamp holder assembly 30, secured with bolts to prevent loosening during lamp use. The plug 42 is also made of copper and its shape matches the socket 41, allowing for a tight fit and ensuring good electrical contact. The plug 42 is installed inside the connector 31 near the lamp holder assembly. After the lamp holder assembly 30 is rotated and connected to the connector 31, the plug 42 can be smoothly inserted into the socket 41, achieving an electrical connection. The lampshade 322 is also made of plastic, and a circuit board 323 is fixedly installed inside the lampshade 322 using clips. Circuit board 323 is a common printed circuit board (PCB), on which various electronic components and circuits are arranged to control and adjust the operation of lamp body 321. Circuit board 323 and lamp body 321 are electrically connected by wires. The wires are made of high-temperature resistant and highly insulating silicone wires to ensure that no short circuits or other safety problems occur due to temperature rise during lamp operation.

[0043] The circuit board 323 has connecting contacts made of copper foil, which has good conductivity. When the lampshade 322 is assembled with the connector 31 through the connecting hole 3221, the connecting contacts on the circuit board 323 make contact with the lower end of the socket 41, thereby achieving electrical conductivity between the circuit board 323 inside the lampshade 322 and the electrical connector 40 in the connector 31, thus providing a stable power supply to the lamp body 321. For example, when the lamp is powered on, the current flows sequentially through the lamp arm assembly 20, the socket 41 and plug 42 in the connector 31, the circuit board 323 inside the lampshade 322, and finally reaches the lamp body 321, enabling the lamp body 321 to emit light normally. This design not only ensures the stability of the electrical connection of the lamp, but also ensures that the connecting contacts and the socket 41 maintain good contact during the rotation of the lamp head assembly 30 and the lampshade 322, preventing power outages due to rotation, thus improving the reliability and service life of the lamp.

[0044] In some embodiments of this utility model, the lamp body 321 includes a lamp board and lamp beads, with the lamp beads disposed on the lamp board, which is made of a transparent material. The lamp board is made of a transparent material with extremely high light transmittance, allowing the light emitted by the lamp beads to pass through almost without loss, ensuring the lighting effect of the lamp and making the light brighter and more uniform. Simultaneously, acrylic material also has good weather resistance and chemical stability, maintaining stable performance under different environmental conditions, such as high temperature, humidity, or places corroded by chemicals, and is not prone to yellowing, deformation, or damage, greatly extending the lifespan of the lamp board. The lamp beads are high-brightness light-emitting diode (LED) beads, featuring energy saving, high efficiency, and long lifespan. Multiple LED beads are evenly distributed on the lamp board according to the lighting requirements of the lamp. These lamp beads are firmly soldered to the lamp board using surface mount technology (SMT), ensuring that they will not loosen or fall off during the use of the lamp.

[0045] Reference Figure 1 as well as Figure 4 In some embodiments of this utility model, the lamp arm assembly 20 includes multiple cantilever arms 21 and multiple rotary joints 22. The cantilever arms 21 are connected to each other via rotary joints 22. The lamp holder assembly 10 is rotatably connected to the cantilever arms 21 via rotary joints 22, and the lamp head assembly 30 is rotatably connected to the cantilever arms 21 via rotary joints 22. Specifically, there are three rotary joints 22, namely a first joint, a second joint, and a third joint. The first joint can connect between the lamp head assembly 30 and the cantilever arms 21, the second joint can connect between two adjacent cantilever arms 21, and the third joint can connect between the lamp holder assembly 10 and the cantilever arms 21.

[0046] In this embodiment, the lamp arm assembly 20 consists of multiple cantilever arms 21 and multiple rotary joints 22. These components work together to enable the lamp to be flexibly adjusted in multiple angles and directions. The cantilever arms 21 are made of high-strength aluminum alloy, which not only has sufficient strength to support the weight of the lamp head assembly 30 and ensure the stability of the lamp during use, but is also relatively lightweight, making it easy to install and move. The rotary joints 22 are key components of the lamp arm assembly 20. One end of the cantilever arm 21 is rotatably connected to the lamp holder assembly 10 through a rotary joint 22 (i.e., the third joint). This rotary joint 22 allows the cantilever arm 21 to rotate at a large angle in the rotational direction, allowing the user to adjust the approximate position of the lamp arm in space according to actual needs. The other end of the cantilever arm 21 is connected to another cantilever arm 21 through another rotary joint 22 (i.e., the second joint). Similarly, this rotary joint 22 allows the cantilever arms 21 to rotate at a large angle in the rotational direction, further expanding the adjustment range of the lamp. The other end of another cantilever 21 is connected to yet another cantilever 21 via a rotating joint 22 (i.e., another second joint). This third cantilever 21 can also rotate at a certain angle in the rotational direction to meet the needs of more precise lighting angle adjustment. The lamp head assembly 30 is rotatably connected to the end of the third cantilever 21 via a rotating joint 22 (i.e., the first joint). This rotating joint 22 is designed to be more flexible, allowing the lamp head assembly 30 to rotate at multiple angles in the rotational direction. Simultaneously, it rotates in conjunction with the structure where the lamp head assembly 30 and the lamp arm assembly 20 are slidably mounted on the slide groove 3121 via a protrusion 3222, thus achieving omnidirectional and multi-angle adjustment of the light emission direction of the lamp head 32. For example, when users need to use this lamp in different work scenarios, such as reading, drawing, or crafting, they can easily adjust the lamp head 32 to the most suitable lighting angle by simply operating these rotating joints 22 and rotating the lamp head assembly 30, providing users with a comfortable and efficient lighting experience. The design of this lamp arm assembly 20 is compact and easy to operate, which greatly improves the practicality and flexibility of the lamp.

[0047] Reference Figure 1 as well as Figure 4 In some embodiments of this utility model, the rotary joint 22 includes two rotary seats 221, two turntables 222, and a locking screw 223. The two turntables 222 are rotatably sleeved on both ends of the locking screw 223. A torsion spring 224 is sleeved on the outer side of the locking screw 223. The torsion spring 224 is located between the two turntables 222, and both ends of the torsion spring 224 are respectively engaged with the two turntables 222. A friction plate 225 is sleeved on one end of the locking screw 223, and a locking nut 226 is screwed to the other end of the locking screw 223. The inner sides of the two rotary seats 221 are respectively connected to the outer sides of the two turntables 222.

[0048] In this embodiment, the rotary joint 22 specifically includes key components such as two rotating seats 221, two turntables 222, and locking screws 223. The components work together to achieve a flexible and stable rotational connection between the lamp components.

[0049] The two rotating bases 221 form the foundation for connecting the rotating joint 22 to other components of the lighting fixture. Both are made of high-strength aluminum alloy to ensure structural strength and dimensional accuracy. Each rotating base 221 has an inner connection structure adapted to the turntable 222, which includes both snap-fit ​​and screw connections. The two turntables 222 are also made of high-strength aluminum alloy and are flat discs to ensure stability during rotation. A through hole is located at the center of each turntable 222 for mounting a locking screw 223. The locking screw 223 is a core component of the rotating joint 22 and is made of stainless steel, offering good strength and corrosion resistance. The two ends of the locking screw 223 are rotatably fitted with the two turntables 222, allowing the turntables 222 to rotate freely around the locking screw 223. A torsion spring 224 is sleeved on the outside of the locking screw 223. The torsion spring 224 is located between the two turntables 222, and its two ends are respectively engaged in the pre-set slots on the two turntables 222. At the same time, the distance between the turntables 222 allows the torsion spring 224 to be compressed axially, giving it a preload. When the turntables 222 rotate, the torsion spring 224 generates a corresponding elastic force, providing power for the turntables 222 to reset, thereby making the rotation of the rotary joint 22 smoother. A friction plate 225 is sleeved on one end of the locking screw 223. The friction plate 225 is made of a high-friction coefficient composite material. Through the preload of the torsion spring 224, the turntables 222 compress the friction plate 225 axially and outward, which can effectively increase the resistance during rotation, so that the turntables 222 can remain stable after rotating to the required angle and will not easily rotate due to external forces. The other end of the locking screw 223 is screwed with a locking nut 226. The locking nut 226 adopts a thread specification that matches the locking screw 223. After the user adjusts the angle of the turntable 222, the locking screw 223 can be made to have a certain axial displacement by tightening the locking nut 226, thereby compressing the friction plate 225, increasing the friction between the friction plate 225 and the turntable 222, and realizing the locking of the angle of the turntable 222.

[0050] In practical use, when it is necessary to adjust the angle of the lamp components, the user only needs to gently rotate the lamp components connected to the turntable 222, such as the lamp head assembly 30 or the cantilever 21. The turntable 222 will rotate around the locking screw 223, and the torsion spring 224 will deform simultaneously. After rotating to the desired angle, tightening the locking nut 226 or increasing the friction between the friction plate 225 and the turntable 222 through the original friction between the friction plate 225 and the turntable 222 will fix the turntable 222 in the current position, thereby achieving stable adjustment of the lamp component angle. This rotary joint 22 design is compact and easy to operate, and can meet the angle adjustment needs of lamps in different usage scenarios.

[0051] Reference Figure 1 In some embodiments of this utility model, the lamp holder assembly 10 has a mounting portion 11, and the lamp arm assembly 20 is rotatably connected to the mounting portion 11 about its axis. The mounting portion 11 is located at the top center of the lamp holder assembly 10, and it can be a bushing structure made of metal. The bushing is made of high-quality stainless steel, precision machined, with a smooth inner wall and high dimensional accuracy. Its diameter matches the rotating shaft on the lamp arm assembly 20 used for connection, ensuring that the rotating shaft can rotate smoothly within the bushing. The outer side of the bushing is connected to the main body of the lamp holder assembly 10 by multiple reinforcing ribs, which are radially distributed to further enhance the structural strength of the mounting portion 11, enabling it to withstand various stresses generated when the lamp arm assembly 20 rotates. Correspondingly, one end of the lamp arm assembly 20 is provided with a rotating shaft adapted to the mounting portion 11. The rotating shaft is also made of stainless steel, and its surface is polished to reduce the coefficient of friction with the bushing. During installation, the rotating shaft of the lamp arm assembly 20 is inserted into the bushing of the mounting part 11 of the lamp holder assembly 10. Due to the good dimensional accuracy of the bushing and the rotating shaft, the lamp arm assembly 20 can rotate flexibly around the axis of the mounting part 11.

[0052] In practical use, users can easily rotate the lamp arm assembly 20 to allow it to rotate 360 ​​degrees around the axis of the mounting part 11 of the lamp holder assembly 10, according to different usage scenarios and lighting needs. For example, when lighting is needed in different areas of a room, simply rotate the lamp arm assembly 20 and adjust the lamp head 32 to the appropriate position to achieve flexible lighting adjustment, greatly improving the practicality and convenience of the lamp.

[0053] Reference Figure 1In some embodiments of this utility model, the lamp holder assembly 10 has a clamp mounting base 12, which is detachably mounted on the mounting position. The clamp mounting base 12 is located at the bottom of the lamp holder assembly 10 and specifically consists of several key parts. First, there is an adjustable clamping arm structure. The clamping arm is made of stainless steel with good elasticity and toughness and is formed by precision stamping. The clamping arm is arc-shaped, with one end connected to the bottom of the lamp holder assembly 10 via a rotating shaft, allowing for rotation at a certain angle to adapt to mounting positions of different shapes and sizes. The other end is a clamping end, with an anti-slip rubber pad on its inner side. The surface of the rubber pad has fine texture to increase friction with the mounting position and prevent the lamp from sliding or loosening during use. At the middle of the clamping arm, there is a threaded adjusting rod. One end of the adjusting rod engages with a nut fixed to the bottom of the lamp holder assembly 10. By rotating the adjusting rod, the clamping arm can be opened and closed. When you need to install the lamp on the edge of a table, bed, or other similar location, first open the clamping arm to the appropriate size, then place the lamp in the installation position, ensuring that the clamping end of the clamping arm is against the other side of the installation position. Next, rotate the adjusting rod to gradually tighten the clamping arm until the lamp is securely fixed in the installation position.

[0054] When it is necessary to remove the light fixture from its installation position, simply rotate the adjusting rod in the opposite direction to loosen the clamp arm, and then remove the light fixture. This detachable clamp mounting base 12 design allows the light fixture to be easily switched between different installation positions, whether it is a desk or bedside table in the home, or a workbench in the office, it can be easily installed and used, greatly improving the practicality and flexibility of the light fixture.
