[0029] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please refer to Figure 2 and Figure 3 A touch-sensitive lifting lamp includes a lamp barrel 1, a main circuit board 6, a light-transmitting lamp cover 3, a lifting device 2, an isolation cylinder 5, and a lighting board 41. The main circuit board 6 is installed on the lamp barrel 1. The light-transmitting lamp cover 3 is liftably installed on the lamp barrel 1. The lifting device 2 is installed on the lamp barrel 1 and connected to the light-transmitting lamp cover 3. The isolation cylinder 5 is connected inside the light-transmitting lamp cover 3 and forms a light-emitting cavity 32 between it and the inner wall of the light-transmitting lamp cover 3. The isolation cylinder 5 is used to house the lifting device 2. The lighting board 41 is installed on the top of the light-emitting cavity 32, and the wires 8 of the lighting board 41 are electrically connected to the main circuit board 6 through the light-emitting cavity 32.

[0031] As can be seen from the above description, the beneficial effects of this utility model are as follows: by using the isolation cylinder 5 to define the light-emitting cavity 32 inside the light-transmitting lamp cover 3 and to house the lifting device 2 inside itself, the lighting panel 41 and its wire 8 are completely isolated from the lifting device 2 in the radial and axial directions, thus completely eliminating the risk of the wire 8 being entangled, squeezed or cut as the light-transmitting lamp cover 3 rises and falls, thereby improving the electrical safety and mechanical reliability of the entire lamp.

[0032] The working principle of the touch-sensitive lifting light is as follows: the main circuit board 6 is powered by an external AC power source or a mobile power supply to power the lighting panel 41 and the lifting device 2. The lifting device 2 is used to drive the light-transmitting lampshade 3 to move up and down relative to the lamp tube 1. When the light-transmitting lampshade 3 rises to the highest position relative to the lamp tube 1, the main circuit board controls the lighting panel 41 to light up and emits illumination light in the light-emitting cavity 32 of the light-transmitting lampshade 3. The illumination light passes through the light-transmitting lampshade 3 to provide illumination for the user. Correspondingly, when the light-transmitting lampshade 3 falls to the lowest position relative to the lamp tube 1, the distance between the lifting device 2 and the light-transmitting lampshade 3 is shortened. The lifting device 2 is contained by the isolation cylinder 5, and the main circuit board stops supplying power to the lighting panel 41, thereby turning off the illumination light.

[0033] Please combine Figure 3 Furthermore, the outer wall of the isolation cylinder 5 is provided with a wire fixing structure 52, and the wire 8 of the lighting panel 41 can be movably connected to the wire fixing structure 52.

[0034] As described above, the fixed wire structure 52 provides movable constraints on the wires 8 of the lighting panel 41, restricting the disorderly swinging of the wires 8 in the light-emitting cavity, while retaining the necessary margin for lifting and lowering, preventing excessive bending or interference with other components, and further reducing the risk of wire breakage.

[0035] Please combine Figure 3 Furthermore, the wire-fixing structure 52 is a wiring channel formed on the outer side wall of the isolation cylinder 5, the wiring channel connecting the top and bottom of the isolation cylinder 5, and the wire 8 passing through the wiring channel.

[0036] As described above, the wiring channel runs through the top and bottom of the isolation cylinder 5, and the wire 8 is hidden in the channel throughout, forming a fixed guide path to achieve invisible wiring, avoid friction, snagging and optical obstruction caused by exposed wire 8, and simplify the assembly process.

[0037] Please combine Figure 2 and Figure 3 Furthermore, the lighting panel 41 is annular and is arranged around the outside of the isolation cylinder 5.

[0038] As described above, the annular lighting panel 41 surrounds the outside of the isolation cylinder 5, with a continuous 360° light-emitting surface, eliminating dark areas and improving luminous flux utilization. The annular layout is coaxial with the isolation cylinder 5, resulting in a compact space and minimizing the outer diameter of the luminaire.

[0039] Please combine Figure 2 and Figure 5Furthermore, it also includes a touch switch 42, which is installed on the top of the light-transmitting lampshade 3, and the wire 8 extending from the touch switch 42 is connected to the lighting panel 41.

[0040] As described above, the touch switch 42 is installed on the top of the light-transmitting lampshade 3. Its wire 8 is connected to the lighting board 41 and then uniformly led to the main circuit board 6, realizing the integrated wiring of the lighting board 41 and the touch switch 42, reducing wiring branches, reducing assembly complexity, and supporting top touch operation, thus improving the user experience.

[0041] Please combine Figure 2 and Figure 3 Furthermore, it also includes a transmission connector 33, which is installed inside the light-transmitting lamp cover 3 and located directly below the receiving cavity 51 of the isolation cylinder 5. The transmission connector 33 is connected to the lifting device 2.

[0042] As described above, the transmission connector 33 is located directly below the receiving cavity 51 of the isolation cylinder 5, so that the linear motion output by the lifting device 2 is transmitted to the light-transmitting lamp cover 3 without deviation, reducing the off-center load torque, making the lifting process smooth and low-noise, and reducing the wear of the sliding pair.

[0043] Please combine Figure 2 and Figure 3 Furthermore, the lifting device 2 includes a drive motor 21 and a threaded rod 22, the transmission connector 33 is a threaded sleeve, the drive motor 21 is installed inside the lamp tube 1 and electrically connected to the main circuit board 6, the threaded rod 22 is installed at the output end of the drive motor 21, and the threaded sleeve is threadedly connected to the threaded rod 22.

[0044] As can be seen from the above description, the drive motor 21, the threaded rod 22 and the threaded sleeve constitute a helical pair, which has the ability to self-lock when power is off, and the light-transmitting lamp cover 3 can be suspended at any height; the threaded transmission has high precision and low cost, and all components are located in the axis area of ​​the lamp tube 1, with a compact layout, which is easy to integrate and control with the main circuit board 6.

[0045] Please combine Figure 2 Furthermore, the top of the light-transmitting lampshade 3 is provided with a detachable mounting cover 4, and the lighting panel 41 and the isolation cylinder 5 are both installed at the bottom of the mounting cover 4.

[0046] As described above, the detachable mounting cover 4 enables the lighting panel 41 and the isolation cylinder 5 to form a modular assembly, which can be installed or removed as a whole without disassembling the lamp cylinder 1 and the lifting device 2, thereby improving the assembly efficiency of the production line and the convenience of later maintenance.

[0047] Please combine Figure 2Furthermore, the mounting cover 4 and the isolation cylinder 5 are integrally formed as a single structure.

[0048] As described above, the mounting cover 4 and the isolation cylinder 5 are integrally formed, which reduces the number of parts, sealing interface and assembly tolerance, improves structural rigidity and dustproof and waterproof level, and reduces mold and assembly costs.

[0049] Furthermore, the wire 8 is a spring wire.

[0050] As described above, the spring wire automatically expands and contracts within its elastic range, matching the lifting and lowering displacement of the lampshade in real time, eliminating redundant wire segment accumulation or tensile stress, further preventing tangling and fatigue breakage, and improving the lifespan of the wire and the reliability of the system.

[0051] Please refer to Figure 1 The first embodiment of this utility model is: a touch-sensitive lifting light, which is suitable for various indoor lighting environments that require frequent adjustment of light height, have high requirements for safety and reliability, or pursue a simple appearance and quiet operation, and can be widely used in reading lighting, ambient lighting, children's night lights, exhibition accent lighting, medical / elderly care, and smart office, etc.

[0052] Please combine Figure 2 and Figure 3 The touch-sensitive lifting light includes a lamp barrel 1, a main circuit board 6, a light-transmitting lamp cover 3, a lifting device 2, a mounting cover 4, an isolation cylinder 5, a touch switch 42, and a lighting board 41; the main circuit board 6 is installed inside the lamp barrel 1; the light-transmitting lamp cover 3 is slidably installed in the lamp barrel 1, and the light-emitting cavity 32 is formed on the inner side of the light-transmitting lamp cover 3; the lifting device 2 is installed inside the lamp barrel 1 and electrically connected to the main circuit board 6, and the lifting device 2 is connected to the light-transmitting lamp cover 3 and is used to drive the light-transmitting lamp cover 3 to slide up and down; Mounting cover 4 is installed on the top of the light-transmitting lampshade 3; isolation cylinder 5 is located at the bottom of mounting cover 4 and inside the light-emitting cavity 32, and the isolation cylinder 5 has a receiving cavity 51 connecting its top and bottom; when the light-transmitting lampshade 3 is lowered, the top of the lifting device 2 is located inside the receiving cavity 51; touch switch 42 is installed on mounting cover 4 and electrically connected to the main circuit board 6 via wire 8; lighting board 41 is installed on mounting cover 4 and electrically connected to the main circuit board 6 via wire 8.

[0053] For specific details, please refer to... Figure 2The touch-sensitive lifting light also includes a base 7, which includes a bottom cover 71 and a base plate 72 installed at the bottom of the bottom cover 71. The lamp tube 1 is installed on the bottom cover 71. The lamp tube 1 has a sliding protrusion 11 inside. The light-transmitting lamp cover 3 has a sliding groove 34 at the corresponding position of the sliding protrusion 11. The sliding protrusion 11 and the sliding groove 34 form a sliding guide engagement, restricting the light-transmitting lamp cover 3 to slide only axially, preventing rotation and lateral shaking, reducing frictional resistance, and improving lifting stability. The top of the mounting cover 4 has a sealing cover 44, which covers the touch switch 42. The sealing cover 44 is covered by a flexible film at the position of the touch switch 42 to facilitate user operation of the touch switch 42.

[0054] Please combine Figure 2 , Figure 3 and Figure 4 The outer wall of the isolation cylinder 5 is provided with a wire-fixing structure 52. Specifically, in this embodiment, the wire-fixing structure 52 is the wiring channel, which connects the top and bottom of the isolation cylinder 5. The wire 8 passes through the wiring channel, thus achieving directional and concealed wiring of the wire 8, preventing the wire 8 from randomly bending or interfering with other components during lifting, and reducing the risk of wire breakage and short circuit. Specifically, the lighting panel 41 is annular and surrounds the outer side of the isolation cylinder 5. The annular lighting panel 41 surrounds the outer side of the isolation cylinder 5, allowing light to be emitted uniformly in the circumferential direction, eliminating dark areas, and making full use of the space around the isolation cylinder 5. The structure is compact and has high optical efficiency. More specifically, please refer to... Figure 4 The bottom of the lighting panel 41 is provided with a plurality of LED beads 411, which are placed upside down inside the light-emitting cavity 32.

[0055] In other embodiments, the wire fixing structure 52 may also be tape, buckle or ring-shaped part wrapped around the isolation cylinder 5. The specific configuration can be set according to the actual application requirements, which will not be elaborated here.

[0056] In addition, in some other embodiments, a reflective layer may be provided on the outer wall of the isolation cylinder 5. It is understood that the reflective layer on the outer wall of the isolation cylinder 5 reflects the light emitted by the lighting panel 41 to the effective lighting area, thereby improving the light energy utilization rate and overall brightness. At the same time, the reflective layer can also serve as a heat dissipation surface, thereby improving thermal management performance.

[0057] Please combine Figure 2 and Figure 3In this embodiment, the touch-sensitive lifting light also includes a transmission connector 33. The transmission connector 33 is installed inside the light-transmitting lampshade 3 and located directly below the receiving cavity 51 of the isolation cylinder 5. The transmission connector 33 is connected to the lifting device 2. The transmission connector 33, installed inside the light-transmitting lampshade 3 and located directly below the receiving cavity 51, and connected to the lifting device 2, enables the linear motion output by the lifting device 2 to be directly transmitted to the light-transmitting lampshade 3, reducing off-center loading and swaying, and improving the stability of the lifting motion. Specifically, the lifting device 2 includes a drive motor 21 and a screw... The threaded rod 22, the transmission connecting part 33 is a threaded sleeve, the drive motor 21 is installed inside the lamp tube 1 and electrically connected to the main circuit board 6, the threaded rod 22 is installed at the output end of the drive motor 21, and the threaded sleeve is threadedly connected to the threaded rod 22. It is easy to understand that the lifting device 2 uses the drive motor 21 and the threaded rod 22, and the transmission connecting part 33 is a threaded sleeve. The threaded sleeve is threadedly connected to the threaded rod 22 to form a spiral lifting mechanism with self-locking characteristics. When the power is off, the light-transmitting lamp cover 3 can maintain its position. The structure is simple, the operation is stable, and the control accuracy is high.

[0058] In addition, in some other embodiments, the lifting device may also consist of a drive motor, a drive gear, and a drive rack, wherein the transmission connector is a sliding sleeve, the sliding sleeve is mounted on the light-transmitting lampshade, the drive motor is mounted on the light-transmitting lampshade, the drive gear is mounted on the output shaft of the drive motor and meshes with the drive rack, the drive rack is vertically fixed to the lamp barrel and slidably connected to the sliding sleeve, and the drive motor drives the drive gear to rotate, thereby causing the light-transmitting lampshade to move up and down relative to the lamp barrel.

[0059] Please refer to Figure 4 and Figure 5 The mounting cover 4 is provided with a wiring through hole 43 connecting its top and bottom. The touch switch 42 is installed on the top of the mounting cover 4, and the lighting panel 41 is installed on the bottom of the mounting cover 4. The lighting panel 41 and the touch switch 42 are electrically connected by a wire 8. It can be understood that the mounting cover 4 is provided with a wiring through hole 43, the touch switch 42 is installed on the top of the mounting cover 4, and the lighting panel 41 is installed on the bottom of the mounting cover 4. The two are electrically connected by a wire 8 through the wiring through hole 43, realizing the separation of the functions of top touch and bottom lighting, while shortening the internal wiring distance, facilitating assembly and maintenance. In this embodiment, the mounting cover 4 and the isolation cylinder 5 are integrally formed, thus reducing the number of parts and assembly processes, improving the overall structural strength and sealing performance, and reducing manufacturing costs.

[0060] Alternatively, the wire 8 can be a spring wire (not shown). It is easy to understand that the wire 8 is made of spring wire, which utilizes its elasticity and stretching characteristics to automatically adjust its length during the lifting and lowering of the light-transmitting lampshade 3, so as to avoid redundant accumulation or excessive stretching of the wire 8, and further prevent tangling and fatigue breakage.

[0061] Please refer to Figure 6 Embodiment 2 of this utility model is a further improvement on Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the base 7 of the touch-sensitive lifting light is further provided with a first wireless charging module 73, a second wireless charging module 74, and a third wireless charging module 75 electrically connected to the circuit board. The first wireless charging module 73 is used to charge wireless Bluetooth headsets, the second wireless charging module 74 is used to charge smartphones, and the third wireless charging module 75 is used to charge smartwatches. With the three-in-one wireless charger integrated at the top of the touch-sensitive lifting light, users can simultaneously magnetically fast charge their mobile phones, headsets, and watches with just one hand, without interfering with the light during the lifting process; this saves space and improves desktop tidiness and nighttime usability.

[0062] In summary, the touch-sensitive lifting light provided by this utility model effectively isolates the lifting device from the wires by setting an isolation cylinder inside the light-transmitting lampshade, forming a receiving cavity inside the isolation cylinder, into which the top of the lifting device can enter, thus preventing the wires from getting tangled. At the same time, a wiring channel is set on the outer wall of the isolation cylinder to further standardize the wire routing and improve the reliability and service life of the lifting light. The lighting panel is set around the outside of the isolation cylinder, with a reasonable layout and uniform lighting. The use of spring wire and sliding guide structure further improves the lifting stability and safety.
