Description
Technical Field
[0001] This utility model relates to the field of desk lamp technology, specifically a desk lamp with a rotatable lampshade. Background Technology
[0002] Current desk lamps, as commonly used lighting devices, primarily focus on basic illumination. Their lampshades are mostly fixed, resulting in limited light distribution and difficulty in creating dynamic and layered ambient lighting effects. Some adjustable desk lamps only offer mechanical adjustments to the beam angle, failing to achieve dynamic changes in light and shadow. The few desk lamps with rotating functions often have uniformly thick lampshades, producing only simple brightness variations when light passes through, lacking subtle light and shadow layers and insufficient immersive atmosphere. To meet users' diverse needs for ambient lighting and address the issues of limited lighting effects and inefficient structural design in existing products, there is an urgent need for a desk lamp with a rotating lampshade that offers dynamic and rich lighting effects, a stable and reliable structure, and convenient installation and maintenance. Utility Model Content
[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a table lamp with a rotatable lampshade, which can effectively solve the problems mentioned in the background art.

[0006] Table lamp holder;
[0007] An electrical conduit is disposed on a lamp holder and extends upward along the axial direction of the lamp holder;

[0011] A lampshade, wherein the lampshade covers the outside of the LED lamp, and the bottom end of the lampshade is fixedly connected to the rotating base;
[0012] The motor drives the motor teeth to rotate, and the motor teeth transmit power to the rotating seat through meshing gears, causing the lampshade to rotate around the axis of the LED lamp.
[0013] As a further description of the above technical solution, the lampshade is a transparent structural component formed by 3D printing, and the wall surface of the lampshade has an uneven contour shape.
[0014] As a further description of the above technical solution, the gearbox includes a gearbox upper cover and a gearbox lower cover, the gearbox upper cover and the gearbox lower cover are fastened together, and the two enclose a sealed cavity for accommodating gears, and the electrical conduit passes through the gearbox upper cover and the gearbox lower cover in sequence.

[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] The table lamp with a rotatable lampshade of this utility model has at least one of the following beneficial effects during use:
[0021] Firstly, the lampshade is driven to rotate around the LED light axis by a power component. Combined with the 3D-printed, unevenly thick transparent lampshade, light passes through different thickness areas, creating differences in brightness and darkness. As the lampshade rotates, it dynamically switches to a flowing and layered ambient lighting effect. Compared to traditional fixed and uniform lampshades, the light and shadow effects are more delicate and immersive, meeting diverse ambient lighting needs. Secondly, the gearbox adopts a sealed cavity design with snap-fit upper and lower covers, effectively isolating dust and moisture, preventing gear corrosion, and ensuring stable power transmission. The electrical conduit runs through the gearbox to achieve axial alignment, ensuring rotational coaxiality. Thirdly, the wires are hidden inside the electrical conduit, avoiding wire pulling and wear, and reducing safety hazards. Fourthly, the rotating base and gearbox are detachably connected. The lampshade precisely matches the rotating base through the mounting bracket, ensuring that the rotation axis is aligned and facilitating cleaning of the lampshade and replacement of parts, reducing maintenance costs. Fifthly, the closed arc-shaped top of the lampshade reflects and scatters light upwards, enhancing the light intensity of the inner wall, amplifying the contrast between light and dark, and further improving the ambient lighting effect. The overall structure is stable, reliable, and highly practical. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figure 1-3 As shown, this utility model provides a table lamp with a rotatable lampshade 4, comprising:
[0029] Table lamp holder 1;
[0030] Electrical conduit 8 is disposed on the lamp holder 1 and extends upward along the axial direction of the lamp holder 1.
[0031] Power assembly 2, which is fixedly connected to the top end of the electrical conduit 8, includes a motor 6 and a reduction gearbox 7. The output end of the motor 6 is provided with motor teeth 13, and the reduction gearbox 7 is provided with a gear 14 that meshes with the motor teeth 13.
[0032] Rotary seat 3, which is connected to the output end of the gearbox 7, and the extending direction of the rotary seat 3 is collinear with the axial direction of the conduit 8;
[0033] LED light 12, which is fixedly mounted on the top area of the rotating base 3;
[0034] Lamp cover 4, which covers the outside of LED lamp 12, and the bottom end of lamp cover 4 is fixedly connected to rotating base 3;
[0035] The motor 6 drives the motor gear 13 to rotate, and the motor gear 13 transmits power to the rotating seat 3 through the meshing gear 14, causing the lamp cover 4 to rotate around the axis of the LED lamp 12.
[0036] In this embodiment, the motor 6 outputs power to the motor gear 13, which meshes with the gear 14 to provide power to the rotating seat 3. The rotating seat 3 then transmits the power to the lampshade 4. The lampshade 4 is 3D printed and has a transparent shape with uneven thickness. When powered on, it will rotate on the rotating seat. Light passing through the lampshade 4 will produce light with alternating brightness and darkness. As the lampshade 4 rotates, it will produce ambient lighting.
[0037] To further explain, the lamp base 1 serves as a supporting base, with the electrical conduit 8 extending upward along its axis. The bottom end of the conduit connects to the lamp base 1, and wires connecting the LED lamp 12 to the external power supply are run through its interior. The power assembly 2 (including the motor 6 and the gearbox 7) is fixed to the top of the electrical conduit 8. The upper and lower covers of the gearbox 7 are fastened together to form a sealed cavity. The gear 14 inside the cavity meshes with the motor teeth 13 at the output end of the motor 6. The rotating base 3 is connected to the output end of the gearbox 7. The LED lamp 12 is fixed to the top area of the rotating base 3. The lampshade 4, through the mounting hole of the bottom mounting base 5, cooperates with the fixing post 11 of the rotating base 3 to cover the LED lamp 12 and is fixed to the rotating base 3.
[0038] After being powered on, the motor 6 starts and outputs power, driving the motor gear 13 at its output end to rotate; the motor gear 13 meshes with the gear 14 in the cavity of the gearbox 7, transmitting power to the gearbox 7. After the gearbox 7 adjusts the speed of the motor 6, it transmits stable power to the rotating seat 3; the rotating seat 3 rotates at a uniform speed along the axis of the conduit 8 (i.e., the axis of the LED lamp 12), synchronously driving the fixedly connected lamp cover 4 to rotate.
[0039] When the LED light 12 is powered on, it emits light with its emitting surface facing the inner wall of the lampshade 4. Since the lampshade 4 is a 3D printed transparent structure with uneven thickness, light will create differences in brightness when it passes through the lampshade 4 walls of different thicknesses. As the lampshade 4 continues to rotate, these differences in brightness dynamically switch with the position of the lampshade 4, ultimately creating a flowing and layered atmospheric lighting effect.
[0040] Furthermore, the lampshade 4 is a transparent structural component formed by 3D printing, and the wall surface of the lampshade 4 has an uneven contour shape.
[0041] The lampshade 4 is precisely controlled using 3D printing technology to achieve a pre-defined uneven profile. When the LED lamp 12 emits light, the thinner areas scatter more light, while the thicker areas scatter less, creating a basic difference in brightness. As the lampshade 4 rotates with the rotating base 3, the brightness and darkness corresponding to these thin and thick areas dynamically switch according to their positions, creating a flowing light and shadow effect.
[0042] Compared to traditional lampshades with uniform thickness, the uneven thickness design can produce multi-gradient changes in brightness, resulting in more delicate lighting layers and a more immersive atmosphere.
[0043] Furthermore, the gearbox 7 includes a gearbox upper cover 10 and a gearbox lower cover 9. The gearbox upper cover 10 and the gearbox lower cover 9 are fastened together, forming a sealed cavity for accommodating the gear 14. The electrical conduit 8 passes through the gearbox upper cover 10 and the gearbox lower cover 9 in sequence.
[0044] The gearbox upper cover 10 and lower cover are fastened together by buckles or screws, completely sealing the gear 14 inside the cavity; the electrical conduit 8 passes through the through holes of the lower cover and upper cover in sequence, sealing the cavity to isolate external dust and moisture, preventing the gear 14 from rusting. The through design of the electrical conduit 8 ensures that the gearbox 7 and the lamp holder 1 are axially aligned, ensuring the coaxial rotation of the rotating seat 3.
[0045] Furthermore, the rotary seat 3 is detachably connected to the output end of the gearbox 7.
[0046] The rotary seat 3 and the output end of the gearbox 7 are connected by a detachable structure such as clips and threads. The rotary seat 3 and the lamp cover 4 can be disassembled separately, which facilitates cleaning of the inner wall of the lamp cover 4 (to avoid dust accumulation affecting light transmission) and replacement of damaged rotary seat 3 and lamp cover 4, without having to disassemble the entire power assembly 2, thus reducing maintenance costs.
[0047] Furthermore, the conduit 8 is installed inside the cavity of the lamp holder 1, and the bottom end of the conduit 8 is connected to the lamp holder 1. The interior of the conduit 8 is used to install wires that connect the LED lamp 12 to the external power supply.
[0048] The conduit 8 has a hollow structure, and the wires connecting the LED light 12 to the external power supply are run inside the conduit 8. The bottom end of the conduit 8 is fixed in the internal cavity of the lamp holder 1, and the top end is connected to the gearbox 7. Concealing the wires avoids the risk of the wires being pulled or worn, and reduces the safety hazards of short circuits and leakage.
[0049] Furthermore, the light-emitting surface of the LED lamp 12 faces the inner wall of the lamp cover 4, and the top of the lamp cover 4 has a closed arc-shaped structure.
[0050] The light-emitting surface of LED 12 faces the inner wall of lampshade 4, directly illuminating the inside of lampshade 4. The closed arc-shaped structure at the top of lampshade 4 reflects the upward-scattered light from LED 12 back to the inner wall of lampshade 4, reducing light dispersion. The reflection effect of the arc-shaped top further enhances the light intensity on the inner wall of lampshade 4, amplifying the contrast between light and dark caused by the uneven thickness, making the ambient lighting more pronounced.
[0051] Furthermore, the bottom of the lampshade 4 is provided with a mounting base 5 connected to the rotating base 3. The mounting base 5 has multiple mounting holes, and the rotating base 3 has multiple fixing posts 11 corresponding to the mounting holes.
[0052] The mounting base 5 at the bottom of the lampshade 4 has three pre-set mounting holes. The fixing posts 11 on the rotating base 3 correspond one-to-one with the mounting holes and are fixed by snap-fit or screws. The overall connection structure ensures the connection accuracy between the lampshade 4 and the rotating base 3, so that the rotation axis of the lampshade 4 is completely aligned with the axis of the LED lamp 12.
[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
