[0002] Existing lifting lights generally include a lamp barrel, a light-transmitting lampshade, an illumination panel, and a lifting device. The illumination panel is installed inside the light-transmitting lampshade, which is liftable and mountable on the lamp barrel. The lifting device is installed on the lamp barrel and connected to the light-transmitting lampshade.

[0003] During use, heat can easily accumulate inside the lampshade and lamp housing, causing the temperature around the lamp panel to rise. Excessive temperature can damage the lamp panel. To address this, some lift-type lamps have ventilation holes in their lampshades. However, these holes are often exposed on the outside of the lampshade, affecting the aesthetics of the lift-type lamp and allowing dust from the external environment to enter the lampshade.

[0032] 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.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 A lifting lamp includes a lamp barrel 1, a light-transmitting lampshade 3, a lifting device 2, a mounting cover 4, and a lighting panel 5; the light-transmitting lampshade 3 is liftably mounted on the lamp barrel 1; the lifting device 2 is mounted on the lamp barrel 1 and connected to the light-transmitting lampshade 3; the mounting cover 4 is mounted on the top of the light-transmitting lampshade 3, and the bottom surface of the mounting cover 4 is provided with a first heat dissipation vent 411 and a second heat dissipation vent 412 that are interconnected, the first heat dissipation vent 411 connecting to the inner space of the light-transmitting lampshade 3, and the second heat dissipation vent 412 connecting to the outer space of the light-transmitting lampshade 3; the lighting panel 5 is located inside the light-transmitting lampshade 3.

[0034] The working principle of the lifting light is as follows: the lifting device 2 and the lighting panel 5 are powered by an external power source or an external mains power supply. The lifting device 2 is used to drive the light-transmitting lampshade 3 to move up and down relative to the lamp barrel 1. When the light-transmitting lampshade 3 rises to the highest position relative to the lamp barrel 1, the main circuit board controls the lighting panel 5 to light up and emit illumination light in the light-emitting cavity 31 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 barrel 1, the main circuit board stops supplying power to the lighting panel 5, thereby turning off the illumination light.

[0035] As can be seen from the above description, the beneficial effects of this utility model are as follows: by setting a first heat dissipation port 411 and a second heat dissipation port 412 that are interconnected at the bottom of the mounting cover 4, and the first heat dissipation port 411 is connected to the inner space of the light-transmitting lamp cover 3 and the second heat dissipation port 412 is connected to the outer space of the light-transmitting lamp cover 3, a hidden heat dissipation path is formed on the top of the light-transmitting lamp cover 3, which directly conducts the heat accumulated around the lighting panel 5 to the outside of the light-transmitting lamp cover 3, reduces the temperature rise of the lighting panel 5 while maintaining the integrity of the appearance, and avoids the heat dissipation holes being exposed to the visible surface, reducing the amount of dust entering the interior of the light-transmitting lamp cover 3.

[0036] Furthermore, there are multiple first heat dissipation vents 411, which are distributed circumferentially around the outer side of the lighting panel 5.

[0037] As described above, multiple first heat dissipation vents 411 are distributed circumferentially around the outer side of the lighting panel 5, so that the hot air around the panel enters the heat dissipation path synchronously, eliminating the local eddies caused by single-sided air intake, reducing the temperature difference on the panel surface, and improving the uniformity of heat dissipation.

[0038] Please combine Figure 4 and Figure 5 Furthermore, there are multiple second heat dissipation vents 412, which are distributed circumferentially around the outer side of the light-transmitting lamp cover 3.

[0039] As described above, multiple second heat dissipation vents 412 are distributed circumferentially around the outer side of the light-transmitting lamp cover 3, so that hot air is evenly discharged along the circumference, avoiding heat backflow caused by the blockage of a single outlet, and maintaining stable heat dissipation efficiency.

[0040] Please combine Figure 4 and Figure 5Furthermore, the mounting cover 4 includes: a lower cover plate 41, installed on the top of the light-transmitting lampshade 3, with the first heat dissipation vent 411 and the second heat dissipation vent 412 located at the bottom of the lower cover plate 41; and an upper cover plate 42, installed on the top of the lower cover plate 41 and forming a heat dissipation space 43 between the upper cover plate 41 and the lower cover plate 41, wherein the heat dissipation space 43 communicates with the first heat dissipation vent 411 and the second heat dissipation vent 412.

[0041] As described above, the lower cover plate 41 and the upper cover plate 42 are stacked to form a closed heat dissipation space 43. The heat dissipation space 43 connects the first heat dissipation port 411 and the second heat dissipation port 412, so that the heat dissipation path is completely clamped between the two plates. This isolates the internal optical cavity of the light-transmitting lamp cover 3 from the external view, and ensures that the heat dissipation channel is detachable and easy to maintain.

[0042] Please combine Figure 5 Furthermore, the upper cover plate 42 is provided with a raised protrusion 422, which is located within the heat dissipation space 43 and abuts against the lower cover plate 41; and / or,

[0043] The lower cover plate 41 is provided with a raised protrusion 422, which is located in the heat dissipation space 43 and abuts against the upper cover plate 42.

[0044] As described above, the raised protrusion 422 forms a support gap with a fixed height within the heat dissipation space 43, so that the height of the space is not affected by changes in assembly pressure, the heat dissipation cross section remains constant, and the space is prevented from being blocked due to deformation of the upper cover plate 42 or the lower cover plate 41.

[0045] Furthermore, the number of the raised protrusions 422 is multiple.

[0046] As described above, multiple raised protrusions 422 jointly bear the load between the upper cover plate 42 and the lower cover plate 41, disperse stress, avoid local indentations or cracks caused by single-point support, and improve the structural strength of the mounting cover 4.

[0047] Furthermore, the plurality of the raised protrusions 422 are evenly spaced around the mounting cover 4 in the circumferential direction.

[0048] As described above, the raised protrusions 422 are evenly spaced along the circumference of the mounting cover 4, so that the heat dissipation space 43 forms equidistant support in the circumference and the space height remains consistent.

[0049] Please combine Figure 4 and Figure 5 Furthermore, the edge of the upper cover plate 42 is provided with an encapsulation extension 421, which surrounds and is connected to the side wall of the lower cover plate 41.

[0050] As described above, the encapsulation extension 421 surrounds the side wall of the lower cover plate 41 to form a shield, hiding the heat dissipation space 43 and the second heat dissipation port 412 inside the extension, so that the external view cannot directly see the heat dissipation port, thus improving the appearance integrity of the lamp.

[0051] Furthermore, the inner sidewall of the encapsulation extension 421 is provided with a snap-fit ​​protrusion 423, and the sidewall of the lower cover plate 41 is provided with a snap-fit ​​groove 413 that engages with the snap-fit ​​protrusion 423; or, the sidewall of the lower cover plate 41 is provided with a snap-fit ​​protrusion 423, and the inner sidewall of the encapsulation extension 421 is provided with a snap-fit ​​groove 413 that engages with the snap-fit ​​protrusion 423.

[0052] As described above, the snap-fit ​​protrusion 423 and the snap-fit ​​groove 413 cooperate to achieve a screwless snap-fit ​​connection between the upper cover plate 42 and the lower cover plate 41. The assembly direction is unique and reversible, which simplifies the assembly process and reduces the number of parts.

[0053] Furthermore, a dustproof mesh is provided at the first heat dissipation vent 411 and / or the second heat dissipation vent 412.

[0054] As described above, the dustproof net covers the first heat dissipation vent 411 and / or the second heat dissipation vent 412, which intercepts external particles while maintaining the flow area, reducing dust from entering the heat dissipation space 43 and the inside of the lamp cover, and extending the maintenance cycle of the lamp.

[0055] Please refer to Figure 1 One embodiment of this utility model is: a lifting light, which is used in scenarios where the light height needs to be frequently adjusted and where there are high requirements for appearance integrity, cleanliness and quiet operation, such as modern home living rooms and bedrooms, museum and luxury goods exhibition spaces, open office and video conferencing areas, hotel and homestay rooms, hospital wards and lecture halls. Its hidden bidirectional heat dissipation structure can achieve efficient cooling and dust prevention while avoiding the exposure of heat dissipation holes from damaging the decorative effect, reducing maintenance frequency and improving long-term reliability.

[0056] Please combine Figure 2 , Figure 3 and Figure 4The lifting lamp includes a lamp barrel 1, a light-transmitting lampshade 3, a lifting device 2, a mounting cover 4, and a lighting panel 5. The light-transmitting lampshade 3 is liftably mounted on the lamp barrel 1, and the lifting device 2 is mounted on the lamp barrel 1 and connected to the light-transmitting lampshade 3. The mounting cover 4 is mounted on the top of the light-transmitting lampshade 3. The bottom surface of the mounting cover 4 has a first heat dissipation vent 411 and a second heat dissipation vent 412 that are interconnected. The first heat dissipation vent 411 connects to the inner space of the light-transmitting lampshade 3, and the second heat dissipation vent 412 connects to the outer space of the light-transmitting lampshade 3. The lighting panel 5 is located inside the light-transmitting lampshade 3, and a light-emitting cavity 31 is formed on the inner side of the light-transmitting lampshade 3. The bottom of the 5 is provided with a plurality of LED beads 51 for lighting, which are located inside the light-emitting cavity 31. It can be understood that by setting a first heat dissipation port 411 and a second heat dissipation port 412 that are interconnected at the bottom of the mounting cover 4, and the first heat dissipation port 411 is connected to the inner space of the light-transmitting lamp cover 3 and the second heat dissipation port 412 is connected to the outer space of the light-transmitting lamp cover 3, a hidden heat dissipation path is formed on the top of the light-transmitting lamp cover 3, which directly conducts the heat accumulated around the lighting panel 5 to the outside of the light-transmitting lamp cover 3, reducing the temperature rise of the lighting panel 5 while maintaining the integrity of the appearance, and avoiding the heat dissipation holes being exposed to the visible surface, thus reducing the amount of dust entering the interior of the light-transmitting lamp cover 3.

[0057] Specifically, the lamp tube 1 is equipped with a main circuit board 6. The lighting panel 5 and the lifting device 2 are both electrically connected to the main circuit board 6. The main circuit board 6 is connected to an external power supply and controls the lifting device 2 and the lighting panel 5 respectively. The lifting device 2 includes a drive motor 21, a threaded rod 22 and a threaded sleeve 23. The threaded sleeve 23 is installed in the light-transmitting lamp cover 3. The drive motor 21 is installed in 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. The threaded sleeve 23 is threadedly connected to the threaded rod 22.

[0058] Please combine Figure 2 and Figure 3The 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 32 corresponding to the position of the sliding protrusion 11. The sliding protrusion 11 and the sliding groove 32 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 mounting cover 4 also has a touch switch 8 inside. The touch switch 8 is electrically connected to the main circuit board 6. The touch switch 8 is used to control the opening and closing of the lifting device 2. The mounting cover 4 is covered by a flexible film at the position corresponding to the touch switch 8 to facilitate user operation of the touch switch 8.

[0059] Optionally, the number of the first heat dissipation vents 411 and the number of the second heat dissipation vents 412 can be set according to actual application requirements. Please refer to the relevant information. Figure 4 and Figure 5 Specifically, in this embodiment, the number of the second heat dissipation vents 412 is further multiplied. The multiple second heat dissipation vents 412 are distributed circumferentially around the outer side of the light-transmitting lamp cover 3, so that hot air is evenly discharged circumferentially, avoiding heat backflow caused by the blockage of a single outlet, and maintaining stable heat dissipation efficiency.

[0060] In other embodiments, the number of the first heat dissipation vents 411 may be multiple. The multiple first heat dissipation vents 411 are distributed circumferentially around the outer side of the lighting panel 5. The multiple first heat dissipation vents 411 are distributed circumferentially around the outer side of the lighting panel 5, so that the hot air around the lighting panel 5 enters the heat dissipation path synchronously, eliminates the local eddy currents caused by unilateral air intake, reduces the surface temperature difference of the lighting panel 5, and improves the uniformity of heat dissipation.

[0061] Please combine Figure 4 and Figure 5 The mounting cover 4 includes a lower cover plate 41 and an upper cover plate 42. The lower cover plate 41 is installed on the top of the light-transmitting lampshade 3, and the first heat dissipation vent 411 and the second heat dissipation vent 412 are located at the bottom of the lower cover plate 41. The upper cover plate 42 is installed on the top of the lower cover plate 41 and forms a heat dissipation space 43 between the upper cover plate 41 and the lower cover plate 41. The heat dissipation space 43 connects the first heat dissipation vent 411 and the second heat dissipation vent 412. It can be understood that the lower cover plate 41 and the upper cover plate 42 are stacked to form a closed heat dissipation space 43. The heat dissipation space 43 connects the first heat dissipation vent 411 and the second heat dissipation vent 412, so that the heat dissipation path is completely clamped between the two plates, which not only isolates the internal optical cavity of the light-transmitting lampshade 3 from the external view, but also ensures that the heat dissipation channel is detachable and easy to maintain.

[0062] Specifically, the touch switch 8 is installed in the heat dissipation space 43, and the wires extending from the touch switch 8 pass through the first heat dissipation port 411 and through the light-emitting cavity 31 inside the light-transmitting lamp cover 3 and are electrically connected to the main circuit board 6.

[0063] Please combine Figure 5 The upper cover plate 42 is provided with a raised protrusion 422, which is located within the heat dissipation space 43 and abuts against the lower cover plate 41; and / or, the lower cover plate 41 is provided with a raised protrusion 422, which is located within the heat dissipation space 43 and abuts against the upper cover plate 42. It is easy to understand that the raised protrusion 422 forms a support gap of a fixed height within the heat dissipation space 43, ensuring that the height of the space is not affected by changes in assembly pressure, maintaining a constant heat dissipation cross-section, and preventing damage due to changes in the upper cover plate 42 or the lower cover plate. 41 Deformation leads to space obstruction; specifically, there are multiple raised protrusions 422, which together bear the load between the upper cover plate 42 and the lower cover plate 41, disperse stress, avoid local indentations or cracks caused by single-point support, and improve the structural strength of the mounting cover 4; more specifically, the multiple raised protrusions 422 are evenly spaced around the circumference of the mounting cover 4, so that the heat dissipation space 43 forms equidistant support in the circumference and the space height remains consistent.

[0064] Please combine Figure 4 and Figure 5 The upper cover plate 42 has an encapsulation extension 421 on its edge. The encapsulation extension 421 is connected to the side wall of the lower cover plate 41 around the side wall of the lower cover plate 41. The encapsulation extension 421 forms a shield around the side wall of the lower cover plate 41, hiding the heat dissipation space 43 and the second heat dissipation port 412 inside the extension. The heat dissipation port cannot be directly seen from the outside, improving the appearance integrity of the lamp. Specifically, the inner side wall of the encapsulation extension 421 has a snap-fit ​​protrusion 423, and the side wall of the lower cover plate 41 has a snap-fit ​​groove 413 that snaps into the snap-fit ​​protrusion 423; or, the side wall of the lower cover plate 41 has a snap-fit ​​protrusion 423, and the inner side wall of the encapsulation extension 421 has a snap-fit ​​groove 413 that snaps into the snap-fit ​​protrusion 423. It is easy to understand that the snap-fit ​​protrusion 423 and the snap-fit ​​groove 413 cooperate to realize the screwless snap-fit ​​connection between the upper cover plate 42 and the lower cover plate 41. The assembly direction is unique and reversible, simplifying the assembly process and reducing the number of parts.

[0065] Optionally, a dustproof net (not shown) may be provided at the first heat dissipation vent 411 and / or the second heat dissipation vent 412. The dustproof net covers the first heat dissipation vent 411 and / or the second heat dissipation vent 412, and while maintaining the flow area, it intercepts external particles, reduces dust from entering the heat dissipation space 43 and the inside of the lamp cover, and extends the maintenance cycle of the lamp.

[0066] Please refer to Figure 6 Embodiment 2 of this utility model is a further improvement based on Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the base 7 of the 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, which are electrically connected to the main circuit board 6. 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 into 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.

[0067] In summary, the lifting lamp provided by this utility model has a first heat dissipation vent and a second heat dissipation vent that are interconnected at the bottom of the mounting cover. The first heat dissipation vent is connected to the inner space of the light-transmitting lamp cover, and the second heat dissipation vent is connected to the outer space of the light-transmitting lamp cover. This forms a hidden heat dissipation path at the top of the light-transmitting lamp cover, which directly conducts the heat accumulated around the lighting panel to the outside of the light-transmitting lamp cover. This reduces the temperature rise of the lighting panel while maintaining the integrity of the appearance, and avoids the heat dissipation holes being exposed on the visible surface, thus reducing the amount of dust entering the interior of the light-transmitting lamp cover.
