Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, specifically to a lamp holder and its folding table lamp. Background Technology

[0002] Existing folding desk lamps have a single, strip-shaped lamp head that only allows for tilt adjustment. Because they lack a fixed, integrated structure, the lamp head shape cannot be adjusted. During shipping, the lamp head shape is fixed, and it can only fold into the lamp holder. There is no folding storage structure on the lamp head, resulting in a large transport space and a bulky packaging volume. For example, a novel eye-protecting desk lamp disclosed in Chinese Patent Publication No. CN118882021A includes a base, a support rod unit, and a lamp head. One end of the support rod unit is mounted on the base, and the other end is connected to the lamp head. The lamp head is laterally rotatable on the support rod unit and lacks a folding structure.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0045] See Figures 1-28 A lamp head includes a lamp head body 1, wherein the lamp head body 1 includes a first spotlight assembly 2 and a second spotlight assembly 3, which are respectively rotatably connected to a control device 4; by rotating the first spotlight assembly 2 and / or the second spotlight assembly 3, the included angle A between the two spotlight assemblies can be adjusted to achieve various unfolding forms of the lamp head body 1; when the two spotlight assemblies rotate toward the inside of the control device 4, both spotlight assemblies are folded onto the control device 4; The control device 4 includes a control circuit board 401, and both the first spotlight assembly 2 and the second spotlight assembly 3 include a light assembly 5 that is electrically connected to the control circuit board 401.

[0046] The lamp head body 1 is rotatably connected to the control device 4 via the first spotlight assembly 2 and the second spotlight assembly 3. The included angle A between the two spotlight assemblies can be adjusted to achieve various unfolding forms to meet different lighting needs. When the two spotlight assemblies rotate toward the inside of the control device 4, they can be folded onto the control device 4, significantly reducing the size of the lamp head and solving the problems of large transportation space and large packaging volume.

[0047] The first spotlight assembly 2 and / or the second spotlight assembly 3 are respectively provided with a rotation limit structure at the rotation connection between them and the control device 4, so as to limit the rotational travel trajectory of the spotlight assembly on the control device 4. The rotation limiting structure includes an anti-rotation member 6 fixedly connected to the rotation point of the corresponding spotlight assembly, and a first anti-rotation step 402 and a second anti-rotation step 403 disposed in the control device 4. The anti-rotation member 6 is provided with a protrusion 601. When the spotlight assembly rotates in the first direction until the first end of the protrusion 601 abuts against the first anti-rotation step 402, the spotlight assembly stops rotating. When the spotlight assembly rotates in the second direction until the second end of the protrusion 601 abuts against the second anti-rotation step 403, the spotlight assembly stops rotating.

[0048] The control device 4 limits the rotational travel trajectory of the spotlight assembly. This prevents the spotlight assembly from rotating excessively in the first or second direction. The limiting method is simple and reliable, requiring no additional complex components. While ensuring adjustment flexibility, it improves the stability and safety of the lamp head, ensuring that the spotlight assembly always rotates within a reasonable range.

[0049] The control device 4 includes a control box 414 for mounting a control circuit board 401. A rotatable connection structure is provided between the side of the control box 414 and each spotlight assembly, so that each spotlight assembly can rotate on the side of the control box 414. The rotating connection structure includes a connecting ear 415 disposed on the side of the control box 414 and a connector 7 disposed on each spotlight assembly. The connector 7 is provided with an annular groove 701. The lower part of the connecting ear 415 is provided with a protruding rib 404 that abuts against the annular groove 701. The protruding rib 404 and the annular groove 701 are arc-shaped to allow relative rotation between the connecting ear 415 and the connector 7.

[0050] The rotating connection structure between the control box 414 of the control device 4 and the spotlight assembly is achieved through the connecting ear 415 on the side of the control box 414, the connector 7 on the spotlight assembly, and the annular groove 701 of the connector 7 and the protruding rib 404 at the bottom of the connecting ear 415 (arc-shaped fit). The arc-shaped fit makes the rotation smoother.

[0051] The control box 414 is also provided with a rotation damping structure at the rotatable connection between its side and each spotlight assembly to realize rotation damping and angle positioning functions. The rotation damping structure includes a hollow inner cavity 405 disposed within the connecting lug 415, and an anti-rotation member 6 rotatably mounted on the hollow inner cavity 405; one end of the connecting member 7 is inserted into the hollow inner cavity 405 and fixedly connected to the anti-rotation member 6; the anti-rotation member 6 is provided with a protrusion 601 for abutting against the inner wall of the hollow inner cavity 405, the protrusion 601 and the inner wall of the hollow inner cavity 405 form a tight fit, thereby generating damping during relative rotation.

[0052] The protrusion 601 of the anti-rotation component 6 fits tightly against the inner wall of the hollow cavity 405. The damping generated during relative rotation allows the spotlight assembly to remain stably stationary at any adjustable angle, preventing easy displacement due to external forces and improving ease of use. At the same time, the damping structure eliminates the need for additional locking components, simplifying the structural design and ensuring smooth rotation adjustment and reliable angle positioning, adapting to different lighting angle requirements.

[0053] The control box 414 includes an upper shell 406 and a lower shell 407 that are fixedly connected. An expansion cavity 408 for mounting a circuit board 409 and an electrical component 410 is provided between the upper shell 406 and the lower shell 407. The circuit board 409 is electrically connected to the control circuit board 401, and the electrical component 410 is electrically connected to the circuit board 409.

[0054] The control circuit board 401 has three spring-loaded buttons for adjusting the light brightness and light mode (daylight mode and night mode). The three spring-loaded buttons are electrically connected to the control circuit board 401.

[0055] The device element 410 can be a human body sensor switch, a speaker, or a lighting bulb.

[0056] The upper shell 406 and lower shell 407 of the control box 414 are fixedly connected to form an expansion cavity 408, which can stably mount the control circuit board 401 and the circuit board 409, protecting the internal electrical components from external interference and improving circuit stability. The human body induction switch of the circuit board 409 extends from the clearance hole at the bottom of the lower shell 407, allowing the user to control the lamp head to start and stop without manual operation, thus improving ease of use. Furthermore, the clearance hole design ensures that the sensing range of the human body induction switch is not obstructed.

[0057] Both the first spotlight assembly 2 and the second spotlight assembly 3 include a housing 8 for fixing and mounting the lighting assembly 5. The lighting assembly 5 includes a lighting panel 501 and a light-emitting element 502 disposed on the lighting panel 501 and electrically connected to the lighting panel 501.

The cavity of the housing 8 has a light-transmitting plate 9 and a second insertion slot 802 for inserting the light-transmitting plate 9. The light-transmitting plate 9 is located below the light-emitting element 502.

[0058] The housings 8 of the first spotlight assembly 2 and the second spotlight assembly 3 have cavities. The light panel 501 of the lighting assembly 5 can be quickly installed via the first insertion slot 801, ensuring convenient and stable installation and preventing displacement of the light panel 501 that could affect lighting. The light-transmitting plate 9, installed in the second insertion slot 802, is located below the light-emitting element 502, evenly diffusing the light from the light-emitting element 502 and preventing direct, glaring light, thus improving lighting comfort. The open surface of the cavity ensures normal light output, while the housing 8 simultaneously protects the lighting assembly 5 and the light-transmitting plate 9, reducing damage from external impacts and balancing installation convenience, lighting effect, and structural protection.

[0059] The housing 8 is open at one end and forms a plug-in installation with the connector 7; the connector 7 is provided with a first wire hole 702 for connecting the cavity of the housing 8, the anti-rotation member 6 is provided with a second wire hole 602 for connecting the first wire hole 702, the light assembly 5 has a light board 501 with a first wire harness, the first end of the first wire harness is electrically connected to the light board 501, and the second end of the first wire harness enters the control box 414 from the first wire hole 702 through the second wire hole 602 and is electrically connected to the control circuit board 401; the control box 414 is provided with a third wire hole 412 for passing the wire harness through.

During this process, the desk lamp wiring harness has been pre-arranged neatly through the hollow parts of the first connecting arm 1001 and the second connecting arm 1002, as well as the wire grooves 16 of the first connector 11, the second connector 14, and the third connector 15, to avoid touching the wiring harness when installing the components. Next, rotate the second connecting arm 1002 and the first connecting arm 1001 to adjust the height of the lamp holder 10: the two rotate through the second connector 14 and the third connector 15. The wire harness is naturally arranged in the hollow part and the wire groove 16. The channel structure of the wire groove 16 restricts the displacement of the wire harness and prevents the wire harness from being pulled or stuck when rotating. At the same time, the hollow part provides enough space to avoid the wire harness and does not affect the smoothness of rotation. This is the conventional technical design of existing folding table lamps. Then rotate the control box 414 of the lamp head and the first connector 11 of the first connecting arm 1001 to adjust the overall angle of the lamp head: the connecting part 411 of the control box 414 rotates around the first fixing ear 1101, and the notch 413 of the control box 414 always corresponds to the wire groove 16 of the first connector 11, so that the wire harness passing through the notch 413 is always in the extension channel of the wire groove 16, and will not be offset or rubbed due to rotation, thus ensuring the stable connection between the wire harness and the control circuit board 401. Then, the first spotlight assembly 2 and the second spotlight assembly 3 are rotated to adjust the lighting angle: the rotation is achieved by the cooperation of the annular groove 701 and the rib 404 of the connecting ear 415 of the connector 7 and the control box 414. At this time, the first wire harness of the light panel 501 passes out from the housing 8 and enters the third wire harness 412 of the control box 414 through the first wire passage 702 of the connector 7 and the second wire passage 602 of the anti-rotation member 6. The three wire passages form a fixed wiring channel. When rotating, the position of the channel moves synchronously with the connector 7 and the anti-rotation member 6. The wire harness is always arranged in an orderly manner in the channel and there will be no messy tangling or friction with other parts. At the same time, the damping effect of the protrusion 601 of the anti-rotation member 6 and the inner wall of the hollow inner cavity 405 keeps the spotlight assembly at the required angle. The damping structure does not contact the wire harness, further avoiding damage to the wire harness. During use, the human body sensor switch 410 senses a human body approaching and controls the lamp head to start and stop. The light-emitting element 502 of the light assembly 5 emits light evenly through the light-transmitting plate 9. During this process, the wiring harness remains stably connected and there is no rotation that affects the smoothness of its circuit. When storing, first rotate and fold the first spotlight assembly 2 and the second spotlight assembly 3 toward the inside of the control box 414; then rotate the first connecting arm 1001 and the second connecting arm 1002 to fold the lamp holder 10. The structure of the wire groove 16 and the hollow part restricts the wire harness from being exposed, thus achieving a reduction in overall volume and keeping the wire harness intact.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
