Description

Technical Field

[0001] This application belongs to the field of lighting technology, and more specifically, relates to a lighting fixture. Background Technology

[0002] Currently, cabinet interior lighting largely relies on traditional light fixtures, which generally suffer from two major drawbacks: First, the limited size of the luminous surface results in a narrow illumination range, making it difficult to provide uniform and sufficient coverage of the cabinet interior. This is especially problematic in cabinet corners or areas with multiple shelves, easily creating blind spots that obstruct the view when users are retrieving items, affecting both convenience and safety. Second, some cabinet lights equipped with infrared human body sensors have fixed, non-adjustable sensor heights, making it impossible to adapt to variations in cabinet height, internal shelf layout, and other differences. Utility Model Content

[0003] The purpose of this application is to provide a lighting fixture that solves the problems of limited illumination range and the inability to adjust the height of the sensor module in existing lighting fixtures.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides a lighting fixture, including a ring light, a height adjustment assembly, and a sensor module. The ring light is used for emitting light and includes a lampshade. The height adjustment assembly includes a first sleeve, a second sleeve, and an elastic element. The first sleeve is fixedly connected to the lampshade, and the second sleeve is sleeved inside the first sleeve. One end of the elastic element abuts against the second sleeve, and the other end of the elastic element abuts against the lampshade. A limiting structure is provided inside the first sleeve, and a limiting block is provided on the outer side of the second sleeve. The limiting block cooperates with the limiting structure to adjust the height of the second sleeve within the first sleeve. The sensor module is connected to the end of the second sleeve away from the elastic element.

[0006] Based on this, the ring light can provide 360° uniform illumination, which helps to eliminate blind spots in cabinet lighting. The first sleeve is fixed to the lampshade, and the second sleeve is fitted inside. The elastic element provides the restoring force, and together with the limiting structure and limiting block, the height of the second sleeve can be adjusted, so that the sensor module can be adapted to different cabinet shelf heights, ensuring accurate sensing of human activity. The overall structure takes into account both lighting and sensing flexibility.

[0007] In one possible design, a limiting ring is provided at one end of the first sleeve. The outer diameter of the limiting ring is the same as the inner diameter of the first sleeve. The inner diameter of the limiting ring is greater than or equal to the outer diameter of the second sleeve. The inner diameter of the limiting ring is less than the sum of the outer diameter of the second sleeve and the length of the limiting block.

[0008] Based on this, the limiting ring can restrict the second sleeve from disengaging from the first sleeve. Its inner diameter design ensures smooth lifting and lowering of the second sleeve, and by setting the inner diameter of the limiting ring to be smaller than the size of "the outer diameter of the second sleeve + the length of the limiting block", it prevents the second sleeve with the limiting block from disengaging from the first sleeve, thereby enhancing the structural stability of the height adjustment component and preventing the sensor module from accidentally falling off.

[0009] In one possible design, the first sleeve is provided with guide strips matching the number of limit blocks, a limit plate is provided between two adjacent guide strips, a guide groove is formed between the limit plate and the guide strip, the limit blocks cooperate with the guide groove, and the width of the guide groove is greater than or equal to the width of the limit block.

[0010] Based on this, the guide bar guides the movement of the limiting block, the guide groove provides a sliding path for the limiting block, and the limiting plate and guide bar work together to restrict the lateral displacement of the limiting block, ensuring smooth lifting and lowering of the second sleeve. The width of the guide groove is adapted to the limiting block to avoid jamming and improve the smoothness of height adjustment.

[0011] In one possible design, a limiting groove is provided at the end of the limiting plate away from the limiting ring, and the width of the limiting groove is greater than the width of the limiting block.

[0012] Based on this, a limiting groove is provided for the limiting block to be inserted and fixed. Its width is greater than that of the limiting block, so that when the user rotates the second sleeve, the limiting block can be accurately embedded in the limiting groove, thereby achieving a stable lock of the sensor module at a specific height and preventing height deviation due to vibration during use.

[0013] In one possible design, the side of the limiting plate closest to the guide strip is curved, and the width of the guide groove at the end away from the limiting ring is greater than the width of the guide groove at the end closest to the limiting ring.

[0014] Based on this, the curved design of the limiting plate and the gradually changing width of the guide groove make the limiting block slide more smoothly from the guide groove into the limiting slot, reducing operating resistance. The far end of the guide groove is wider, which facilitates the initial placement of the limiting block into the guide groove and makes it easier for the limiting block to slide smoothly into the guide groove after being removed from the limiting slot, thus improving the ease of operation for height adjustment.

[0015] In one possible design, the lampshade has a groove, one end of the elastic element is located in the groove, and the other end of the elastic element abuts against the second sleeve.

[0016] Based on this, the lampshade is provided with a groove to fix one end of the elastic element, preventing the elastic element from tilting or shifting when compressed, ensuring that the elastic force acts stably on the second sleeve, so that the sensor module can be reliably reset after being raised and lowered, and enhancing the structural reliability of the height adjustment component.

[0017] In one possible design, the lampshade includes a first connecting portion and a second connecting portion. The first connecting portion is annular, and the second connecting portion has a groove. The first and second connecting portions are on different planes, and the second connecting portion is connected to the first connecting portion by multiple connecting plates. The ring lamp includes a lamp holder and a light source plate. The shape of the lamp holder matches the shape of the lampshade. The light source plate is fixedly connected to the lamp holder at the position corresponding to the first connecting portion, and the lampshade is fastened to the lamp holder.

[0018] Based on this, the first and second connecting parts form a height-low structure through a connecting plate, adapting to the installation space requirements of the light source board, height adjustment component, and sensor module. The lamp holder and lampshade are shaped to match, and the light source board is fixed in the corresponding position to ensure a ring-shaped lighting effect. The lampshade is fastened to the lamp holder to achieve overall encapsulation and protect the internal components.

[0019] In one possible design, one end of the connecting plate is connected to the inside of the first connecting part, and the other end of the connecting plate is connected to the outside of the second connecting part. The angle between the connecting plate and the plane containing the first connecting part is 30° to 40°.

[0020] Based on this, the angle between the connecting plate and the first connecting part is 30°-40°, which avoids deformation of the light source board due to too small an angle, and also prevents the lamp height from increasing and the cost from being too large an angle. At the same time, it enhances the overall structural strength of the lampshade and ensures the stability of the support.

[0021] In one possible design, the lampshade is provided with a first hook and a first slot, and the lamp holder is provided with a second hook and a second slot. When the lampshade and the lamp holder are fastened together, the first hook engages with the second slot, and the second hook engages with the first slot.

[0022] Based on this, the first hook and the second slot, and the second hook and the first slot are interlocked to form a double-locking structure, which is more secure than a single hook connection, preventing the lampshade and lamp holder from loosening during use and improving the overall connection reliability of the structure.

[0023] In one possible design, the luminaire also includes a first adjustment button and a second adjustment button, and a driver box is connected to the lamp holder. Both the first adjustment button and the second adjustment button are connected to the driver box.

[0024] Based on this, the first and second adjustment buttons are connected to the driver box and can be used to adjust the sensing extension time and brightness threshold respectively, so that users can adapt the sensing parameters according to their habits and ambient light, avoid false triggering or malfunction, and improve the flexibility and adaptability of the sensor module.

[0047] To address the aforementioned technical problems, this application provides a lighting fixture. (Reference) Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a schematic diagram of the structure of a lamp provided in an embodiment of this application. Figure 2 This is an exploded view of a lamp provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the first sleeve in a lamp provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the second sleeve in a lamp provided in an embodiment of this application.

[0048] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the illustration, an embodiment of this application provides a lighting fixture including a ring lamp 110, a height adjustment assembly 120, and a sensor module 130. The ring lamp 110 is used for emitting light and includes a lampshade 111. The height adjustment assembly 120 includes a first sleeve 121, a second sleeve 122, and an elastic member 123. The first sleeve 121 is fixedly connected to the lampshade 111, and the second sleeve 122 is fitted inside the first sleeve 121. One end of the elastic member 123 abuts against the second sleeve 122, and the other end of the elastic member 123 abuts against the lampshade 111. A limiting structure 1211 is provided inside the first sleeve 121, and a limiting block 1221 is provided on the outer side of the second sleeve 122. The limiting block 1221 cooperates with the limiting structure 1211 to adjust the height of the second sleeve 122 within the first sleeve 121. The sensor module 130 is connected to the end of the second sleeve 122 away from the elastic member 123.

[0049] As the core light-emitting component, the ring light 110 can adopt a ring design similar to a steering wheel. Its lampshade 111 can be made of PC injection molding, which not only allows light to pass through evenly and achieves 360° lighting to eliminate blind spots in the cabinet, but also provides structural support for the entire light fixture and serves as the installation base for the height adjustment component 120.

[0050] The height adjustment assembly 120 is a key component for enabling the height adjustment of the sensor module 130. The first sleeve 121 is fixed at the center of the lampshade 111, forming a stable integral structure to ensure it does not loosen or shift during adjustment. The second sleeve 122 is fitted inside the first sleeve 121 with a clearance fit, allowing the second sleeve 122 to move smoothly up and down along the inner wall of the first sleeve 121, providing a movement track for the height adjustment of the sensor module 130. The elastic element 123 can be a spring, with one end abutting against the end of the second sleeve 122 furthest from the sensor module 130, and the other end directly abutting against the lampshade 111. When the second sleeve 122 is pressed, the spring is compressed and stores elastic force; when released, the elastic force is released, pushing the second sleeve 122 to automatically reset, achieving a rebound function after height adjustment, making operation more convenient for the user.

[0051] The first sleeve 121 has a limiting structure 1211 inside, and the second sleeve 122 has a corresponding limiting block 1221 on its outer side. The limiting block 1221 cooperates with the limiting structure 1211. When the limiting block 1221 is embedded in different positions of the limiting structure 1211, the height of the second sleeve 122 is fixed, thereby driving the sensor module 130 to adjust to the corresponding height. This cooperation method allows the sensor module 130 to be flexibly adjusted according to the actual situation such as the height of the cabinet and the distribution of internal partitions. For example, in a cabinet with multiple partitions, the sensor module 130 can be raised to cover a wider sensing area. In a low cabinet, the height can be lowered to avoid being blocked by the partitions, ensuring that the sensor can accurately capture human activity signals.

[0052] The sensor module 130 can be a PIR infrared human body sensing module, connected to the end of the second sleeve 122 away from the elastic element 123. Its function is to sense human activity inside the cabinet, thereby controlling the on / off switch of the ring light 110. When someone is detected operating the light, the light is triggered to turn on; when no one is active, the light automatically turns off, improving ease of use.

[0053] The first sleeve 121 and the lampshade 111 can be fixed by a snap-fit ​​method, or by using self-tapping screws or other methods to ensure the stability of the connection. In addition to using a spring, the elastic element 123 can also be an elastic rubber column, whose elastic deformation capability can also realize the reset function of the second sleeve 122.

[0054] In this embodiment, the ring light 110's ring design solves the problems of narrow illumination range and blind spots in traditional lamps. The height adjustment component 120, through the cooperation of the sleeve, elastic element 123, and limiting structure 1211, enables flexible height adjustment of the sensor module 130, allowing it to adapt to different cabinet layouts. The sensor module 130 then achieves intelligent control of the lamp by sensing human activity. The synergistic effect of these three components significantly improves the practicality and user experience of the cabinet lighting.

[0055] like Figure 3 As shown, in this embodiment of the application, a limiting ring 1212 is provided at one end of the first sleeve 121. The outer diameter of the limiting ring 1212 is the same as the inner diameter of the first sleeve 121. The inner diameter of the limiting ring 1212 is greater than or equal to the outer diameter of the second sleeve 122. The inner diameter of the limiting ring 1212 is less than the sum of the outer diameter of the second sleeve 122 and the length of the limiting block 1221.

[0056] A limiting ring 1212 is provided at one end of the first sleeve 121 near the sensor module 130. The limiting ring 1212 can be integrally injection molded with the first sleeve 121 (the material is the same as the sleeve, PC). Its outer diameter is the same as the inner diameter of the first sleeve 121, which allows the limiting ring 1212 to serve as an integrated part or end cap inside the first sleeve 121. The limiting ring 1212 is located at the end of the first sleeve 121 away from the lamp cover 111.

[0057] The inner diameter of the limiting ring 1212 is designed to be greater than or equal to the outer diameter of the second sleeve 122. This dimensional relationship ensures that the second sleeve 122 can pass through the limiting ring 1212, maintaining a stable movement trajectory during both pressing adjustment and the reset of the elastic element 123. It prevents frictional resistance due to an excessively small aperture, thus maintaining a smooth height adjustment operation. The inner diameter of the limiting ring 1212 is smaller than the sum of the outer diameter of the second sleeve 122 and the length of the limiting block 1221. When the user adjusts the height of the sensor module 130 upwards, causing the second sleeve 122 to move upwards along the first sleeve 121 to its limit position, the limiting block 1221 on the outer side of the second sleeve 122 will just contact the inner edge of the limiting ring 1212 and be blocked by the limiting ring 1212, preventing further upward movement. This design physically limits the maximum travel of the second sleeve 122, effectively preventing the second sleeve 122 from coming out of the first sleeve 121, thereby avoiding damage to the sensor module 130 or loss of sensing function due to detachment.

[0058] In practical applications, such as when users frequently retrieve items from cabinets and may accidentally bump the sensor module 130, or when excessive force is applied when adjusting the height, the limiting ring 1212 consistently provides protection, ensuring a stable connection between the second sleeve 122 and the first sleeve 121. Through its dimensional design and coordinated operation with other structures, the limiting ring 1212 ensures flexibility in height adjustment while eliminating the risk of component detachment through physical limiting, significantly enhancing the structural stability and safety of the lighting fixture.

[0059] like Figure 2 and Figure 3As shown, the first sleeve 121 is provided with guide strips 1213 matching the number of limiting blocks 1221. A limiting plate 1214 is provided between two adjacent guide strips 1213. A guide groove 1215 is formed between the limiting plate 1214 and the guide strip 1213. The limiting block 1221 cooperates with the guide groove 1215. The width of the guide groove 1215 is greater than or equal to the width of the limiting block 1221.

[0060] The first sleeve 121 has guide strips 1213 inside, which are exactly the same number as the outer limiting blocks 1221 of the second sleeve 122. These guide strips 1213 can be integrally injection molded with the first sleeve 121 (made of the same material PC), and are evenly distributed along the inner wall of the sleeve. Their height is the same as the depth of the first sleeve 121, and they extend from one end near the limiting ring 1212 to the bottom of the sleeve. A limiting plate 1214 is vertically arranged between two adjacent guide strips 1213. The limiting plate 1214 is also fixedly connected to the inner wall of the first sleeve 121, and together with the guide strip 1213 on one side, they form a guide groove 1215, providing a moving channel with limiting and guiding functions for the limiting blocks 1221 of the second sleeve 122.

[0061] The limiting block 1221 on the outer side of the second sleeve 122 is embedded in the guide grooves 1215. The width of the guide groove 1215 is designed to be greater than or equal to the width of the limiting block 1221. This dimensional relationship provides sufficient room for the limiting block 1221 to avoid jamming due to excessive tightness, and also restricts the lateral displacement of the limiting block 1221 through the guide strip 1213 and the side wall of the limiting plate 1214, ensuring that the second sleeve 122 remains basically coaxial with the first sleeve 121 during the lifting and lowering process, without swaying or tilting.

[0062] The main function of the guide strip 1213 is to guide the limiting block 1221 to move in a straight line. Its flat side fits against the limiting block 1221, ensuring that the limiting block 1221 moves along the length direction (i.e., the height direction) of the guide groove 1215, avoiding adjustment jamming caused by deviation. The limiting plate 1214 further strengthens the constraint on the limiting block 1221, preventing it from coming out of the guide groove 1215 during movement. At the same time, it provides stable support for the limiting block 1221, so that the force during pressing and adjustment can be evenly transmitted, improving the consistency of the operating feel.

[0063] The limiting ring 1212 restricts the maximum rising height of the second sleeve 122 to prevent it from coming off. The guide groove 1215, through the cooperation of the guide strip 1213 and the limiting plate 1214, ensures that the second sleeve 122 maintains a stable movement trajectory throughout the entire adjustment stroke. The combination of the two greatly improves the reliability of the height adjustment assembly 120. For example, when the user presses and rotates the second sleeve 122 to adjust the height of the sensor module 130, the limiting block 1221 slides smoothly along the guide groove 1215 without getting stuck due to deviation. After adjustment, it can also be kept at the preset height due to the constraint of the guide groove 1215, avoiding positional deviation caused by slight vibration.

[0064] The guide bar 1213 and the limiting plate 1214 form a guide groove 1215. Through structural design and size matching, the smoothness of height adjustment is ensured, and the structural stability is enhanced by constraining the movement trajectory of the limiting block 1221. This makes the height adjustment of the sensor module 130 more precise and the operation more reliable, further improving the user experience of the lamp.

[0065] like Figure 3 As shown, a limiting groove 1216 is provided at the end of the limiting plate 1214 away from the limiting ring 1212, and the width of the limiting groove 1216 is greater than the width of the limiting block 1221.

[0066] At the end of the limiting plate 1214 furthest from the limiting ring 1212, a limiting groove 1216 is formed by an inward indentation. Its width is designed to be greater than the width of the outer limiting block 1221 of the second sleeve 122.

[0067] When the user needs to adjust the height of the sensor module 130, pressing the second sleeve 122 compresses the elastic element 123. The limiting block 1221 moves along the guide groove 1215 away from the limiting ring 1212 (i.e., the sensor module 130 is lowered). When it moves to the horizontal line of the limiting groove 1216 or below the horizontal line, rotating the second sleeve 122 will allow the limiting block 1221 to smoothly embed itself into the groove because the width of the limiting groove 1216 is slightly larger than its own width. At this time, releasing the second sleeve 122 will cause the elastic force of the elastic element 123 to press the limiting block 1221 tightly into the limiting groove 1216, thus locking the height of the second sleeve 122. If it is necessary to raise the sensor module 130, the operation is reversed: press and rotate the second sleeve 122 to make the limiting block 1221 disengage from the limiting groove 1216, and move along the guide groove 1215 towards the limiting ring 1212 under the action of the elastic element 123, and lock after reaching the target position.

[0068] The limiting groove 1216 can be integrally injection molded with the limiting plate 1214. The width of the limiting groove 1216 is greater than the width of the limiting block 1221. This design is to reduce the difficulty of operation: when the user rotates the second sleeve 122, the limiting block 1221 can be inserted into the groove without precise alignment, avoiding jamming or inability to lock due to excessive tightness. At the same time, the depth of the limiting groove 1216 is sufficient to accommodate the thickness of the limiting block 1221, ensuring that it will not fall off due to slight vibration or touch after locking, so that the sensor module 130 can be stably maintained at the set height. For example, under the middle shelf of a cabinet, inserting the limiting block 1221 into the limiting groove 1216 of the middle position allows the sensor to avoid the shelf from obstructing it and accurately sense the hand picking up the object. In a tall cabinet without a shelf, inserting it into the limiting groove 1216 of the upper position can expand the sensing range and avoid sensing failure.

[0069] This structure, together with the guide groove 1215 and the limiting ring 1212, forms a complete height adjustment system: the guide groove 1215 guides the limiting block 1221 to move smoothly, the limiting groove 1216 provides multiple fixing positions, and the limiting ring 1212 limits the maximum rising height. The three work together to ensure both the flexibility of adjustment and the stability of the position through mechanical locking. Compared to traditional "no-position adjustment" structures, the limiting groove 1216 allows users to quickly find and fix the appropriate height based on the actual layout of the cabinet (such as differences in shelf height), reducing the hassle of repeated adjustments and significantly improving ease of use.

[0070] It should be noted that the limiting groove 1216 can be designed as an arc-shaped groove 1111 or a rectangular groove 1111. The arc-shaped groove 1111 allows the limiting block 1221 to slide more smoothly from the guide groove 1215 into the limiting groove 1216. In addition, according to the common cabinet shelf height, multiple limiting grooves 1216 can be set on the same limiting plate 1214, distributed along the length of the guide groove 1215, to further increase the adjustment levels.

[0071] The limiting groove 1216, in cooperation with the limiting block 1221, adds a height locking function to the guide groove 1215, upgrading the adjustment of the sensor module 130 from "movable" to "fixable". Combined with the reasonable size design, it not only ensures the convenience of operation, but also enhances the structural stability, allowing the lamp to be more accurately adapted to different cabinet scenarios.

[0072] like Figure 3 As shown, the side of the limiting plate 1214 near the guide strip 1213 is curved, and the width of the end of the guide groove 1215 away from the limiting ring 1212 is greater than the width of the end of the guide groove 1215 near the limiting ring 1212.

[0073] The side of the limiting plate 1214 near the guide strip 1213 adopts a smooth curved design (such as an arc), and the guide groove 1215 formed in cooperation with the guide strip 1213 has a "gradual width" feature. The end of the guide groove 1215 away from the limiting ring 1212 (i.e., the end near the bottom of the lamp cover 111) is wider, and the end near the limiting ring 1212 is narrower, with the whole smoothly transitioning from wide to narrow along the height direction.

[0074] The curved side of the limiting plate 1214 gradually curves outward from one end of the guide groove 1215 to the other, naturally increasing the distance between the guide strip 1213 and the limiting plate 1214 (i.e., the width of the guide groove 1215). When the limiting block 1221 on the outer side of the second sleeve 122 moves along the guide groove 1215, the curved side guides the limiting block 1221 to transition smoothly, avoiding increased frictional resistance caused by right angles or acute angles. For example, when the user presses the second sleeve 122 to move the limiting block 1221 from the near end (narrower end) to the far end (wider end), the contact area between the curved side and the limiting block 1221 gradually changes, reducing the possibility of jamming or sticking. Especially when rotating to engage the limiting groove 1216, the curved transition allows the limiting block 1221 to turn more smoothly.

[0075] The guide groove 1215 features a width-differentiation design, with a wider distal end. This allows users to quickly place the limiting block 1221 into the guide groove 1215 during initial installation or adjustment, reducing operational difficulty and enabling initial positioning without precise alignment. The narrower proximal end provides a tighter constraint on the limiting block 1221, reducing lateral sway during movement and ensuring the stability of the second sleeve 122 when it approaches the limiting ring 1212 (i.e., the higher position of the sensor module 130), preventing sensor position shift due to swaying. This design balances ease of operation with stability during adjustment.

[0076] In this embodiment, the curved side can adopt an arc with different curvatures (such as a quarter circle or an elliptical arc), as long as it can achieve a smooth gradient in the width of the guide groove 1215 from the proximal end to the distal end. The width difference of the guide groove 1215 can be adjusted according to the size of the limiting block 1221. Its main function is to ensure that the distal end can easily accommodate the limiting block 1221 and the proximal end can slightly clamp the limiting block 1221, maintaining functional consistency.

[0077] In this embodiment, the curved side of the limiting plate 1214 and the gradient width design of the guide groove 1215 optimize the movement trajectory and force state of the limiting block 1221 through physical structure, reducing jamming and friction during adjustment and improving the smoothness of operation. At the same time, the width difference design takes into account both ease of operation and adjustment stability, making the height adjustment of the sensor module 130 more precise and easier to use, further enhancing the adaptability of the lamp to different cabinet scenarios.

[0078] refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of a lampshade in a lamp fixture provided as an embodiment of this application. Figure 5 As shown, the lampshade 111 is provided with a groove 1111, one end of the elastic member 123 is located in the groove 1111, and the other end of the elastic member 123 abuts against the second sleeve 122.

[0079] In this embodiment, the groove 1111 can be integrally injection molded with the lampshade 111. The groove 1111 can be designed as a V-shaped groove, and its opening angle and depth are designed according to the size of the elastic element 123 (such as a spring), so as to just accommodate one end of the elastic element 123. The other end of the elastic element 123 extends naturally and abuts against the end of the second sleeve 122 away from the sensor module 130, forming a force transmission path of "groove 1111-elastic element 123-second sleeve 122".

[0080] The main function of the groove 1111 is to provide axial positioning and guidance for the elastic element 123. When the user presses the second sleeve 122, the elastic element 123 is compressed axially within the groove 1111. The sidewall of the groove 1111 can constrain the elastic element 123, preventing it from tilting or shifting to either side. If the elastic element 123 is tilted, it may cause uneven force on the second sleeve 122, resulting in problems such as lifting and lowering jamming, incomplete reset, or even component deformation. The groove 1111, through physical limiting, ensures that the elastic element 123 extends and contracts axially, and the elastic force is evenly applied to the second sleeve 122, ensuring the stable operation of the height adjustment component 120.

[0081] The elastic force of the elastic element 123 drives the second sleeve 122 to reset. The groove 1111 ensures the precise direction of the elastic force. Together with the guide groove 1215 constraining the limiting block 1221, the second sleeve 122 moves smoothly and stably during lifting and lowering. For example, when the user presses the sensor module 130 to lower the height, the elastic element 123 is compressed in the groove 1111. The groove 1111 restricts its tilt, ensuring that the elastic element 123 can exert force evenly after the user releases the hand, pushing the second sleeve 122 to rise smoothly and reset along the guide groove 1215.

[0082] Therefore, in this embodiment of the application, the groove 1111 of the lampshade 111 forms a reliable force transmission system with the elastic element 123 and the second sleeve 122 by fixing the position of the elastic element 123 and constraining its deformation direction. This not only ensures the smoothness of height adjustment but also reduces component wear, further improving the structural reliability and service life of the lamp.

[0083] refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of a lamp holder in a lamp fixture provided in an embodiment of this application. Figure 5As shown, the lampshade 111 includes a first connecting portion 1112 and a second connecting portion 1113. The first connecting portion 1112 is annular, and the second connecting portion 1113 has a groove 1111. The first connecting portion 1112 and the second connecting portion 1113 are on different planes, and the second connecting portion 1113 is connected to the first connecting portion 1112 by a plurality of connecting plates 1114. Figure 6 As shown, the ring lamp 110 includes a lamp holder 112 and a light source plate 113. The shape of the lamp holder 112 matches the shape of the lamp cover 111. The light source plate 113 is fixedly connected to the lamp holder 112 at the position corresponding to the first connecting part 1112. The lamp cover 111 is fastened to the lamp holder 112.

[0084] In this embodiment, the lampshade 111 is integrally injection molded from PC and includes a first connecting portion 1112 and a second connecting portion 1113. The first connecting portion 1112 is annular and serves as the main area for light transmission. The second connecting portion 1113 is located at the center of the lampshade 111 and has a groove 1111 for placing an elastic element 123, which is used to cooperate with the height adjustment assembly 120 to raise and lower the sensor module 130. The second connecting portion 1113 and the first connecting portion 1112 are connected by multiple connecting plates 1114, making the overall shape of the lampshade 111 resemble the shape of a steering wheel.

[0085] The first connecting portion 1112 and the second connecting portion 1113 are on different planes and are connected by 3 to 4 evenly distributed connecting plates 1114. The connecting plates 1114 can be integrally formed with the lampshade 111, which not only enhances the overall structural strength of the lampshade 111 but also creates a staggered layout. The first connecting portion 1112 surrounds the outside of the second connecting portion 1113, reserving installation space for the light source plate 113 and avoiding structural interference between the light source plate 113 and the height adjustment component 120 (located in the area of ​​the second connecting portion 1113). At the same time, the height difference provides sufficient longitudinal space for the compression and reset process of the elastic element 123, preventing it from being blocked by the light source plate 113.

[0086] The ring light 110 also includes a lamp holder 112 and a light source plate 113. The lamp holder 112 has a shape that matches the lamp cover 111 (it is ring-shaped overall, with a recessed structure at the center corresponding to the second connecting part 1113). The material can be flame-retardant ABS, which ensures both structural stability and fire resistance. The light source plate 113 can be attached to the lamp holder 112 with thermally conductive adhesive. Its position corresponds exactly to the first connecting part 1112 of the lamp cover 111, ensuring that the light emitted by the light source plate 113 can be evenly transmitted through the annular area of ​​the first connecting part 1112, forming 360° illumination and eliminating the lighting blind spots of traditional lamps.

[0087] The lampshade 111 and the lamp holder 112 are connected by a snap-fit ​​mechanism. The hooks on the edge of the lamp holder 112 engage with the slots in the lampshade 111. After snapping, they tightly enclose the light source board 113 and the internal drive components, providing dust and moisture protection and preventing oil stains and moisture inside the cabinet from corroding the components and affecting their lifespan. At the same time, this snap-fit ​​structure is easy to disassemble, allowing for easy opening and replacement of the light source board 113 or the drive components during later maintenance.

[0088] like Figure 5 As shown, one end of the connecting plate 1114 is connected to the inner side of the first connecting part 1112, and the other end of the connecting plate 1114 is connected to the outer side of the second connecting part 1113. The angle between the connecting plate 1114 and the plane containing the first connecting part 1112 is 30° to 40°.

[0089] In this embodiment, one end of the connecting plate 1114 is connected to the inner side of the first connecting part 1112, and the other end is connected to the outer side of the second connecting part 1113, forming a radial support. This not only evenly transmits the force on the first connecting part 1112 to the second connecting part 1113, avoiding the annular area from being deformed due to force and affecting the lighting effect, but also disperses stress through multiple support points, improving the lampshade 111's resistance to damage during frequent installation and disassembly.

[0090] The first connecting part 1112, as the supporting area of ​​the light source board 113, needs to remain flat to ensure uniform light diffusion. If the angle between the connecting plate 1114 and the first connecting part 1112 is less than 30°, insufficient tilt will lead to uneven distribution of supporting force between the first connecting part 1112 and the second connecting part 1113. After long-term stress, it is easy for the middle to collapse or the edges to warp, which will deform the light source board 113 and affect the 360° lighting effect. When the angle is greater than 40°, although the supporting force is more dispersed, it will significantly increase the overall height of the lampshade 111. This will not only occupy more cabinet interior space, but also increase production costs due to increased material usage and mold complexity.

[0091] The angle between the connecting plate 1114 and the plane containing the first connecting part 1112 is 30° to 40°. This angled angle allows the weight of the first connecting part 1112 to be evenly transferred to the second connecting part 1113 via the inclined connecting plate 1114. Utilizing the principle of triangular stability, this enhances the overall structural strength and ensures that the light source plate 113 remains undeformed over long-term use. It also allows for control over the thickness of the lampshade 111, making it suitable for the installation space of most cabinets while avoiding material waste. Furthermore, the multiple connecting plates 1114 are evenly distributed along the circumference, further distributing the force to various support points and reducing stress concentration at single points, making the lampshade 111 less prone to damage during frequent fastening, disassembly, or minor impacts.

[0092] The angle of the connecting plate 1114 can be finely adjusted within the range of 30°-40° according to the size of the lampshade 111. For example, in a small lampshade 111, the angle of the connecting plate 1114 is 35°, and in a large lampshade 111, the angle of the connecting plate 1114 is 32°. The main design purpose is to balance structural strength and height. The cross-sectional shape of the connecting plate 1114 can also be changed from a flat plate to an arc shape to further improve the resistance to deformation at the same angle.

[0093] In this embodiment, the connection position and angle design of the connecting plate 1114, through precise mechanical optimization, not only ensures the structural stability of the first connecting part 1112 and the flatness of the light source plate 113, but also controls the product height and cost. In conjunction with the functional zoning design of the lampshade 111, it improves the practicality and economy of the lamp.

[0094] refer to Figure 7 , Figure 7 for Figure 1 The diagram shows a cross-sectional view of point A in a lighting fixture. Figure 7 As shown, the lampshade 111 is provided with a first hook 1115 and a first slot 1116, and the lamp holder 112 is provided with a second hook 1121 and a second slot 1122. When the lampshade 111 and the lamp holder 112 are fastened together, the first hook 1115 engages with the second slot 1122, and the second hook 1121 engages with the first slot 1116.

[0095] In this embodiment, the lampshade 111 has a plurality of first hooks 1115 and first slots 1116 evenly distributed along its circumference. The first hooks 1115 are outwardly protruding barb structures, and the first slots 1116 are inwardly recessed rectangular slots. The lamp holder 112 has the same number of second hooks 1121 and second slots 1122 at corresponding positions. The second hooks 1121 are inwardly protruding barb structures, and the second slots 1122 are through-hole rectangular slots located near the second hooks 1121. This design of two sets of cross-fitting "hook-slot" connections is more reliable than a single hook connection.

[0096] When the lampshade 111 is fastened onto the lamp holder 112, the first hook 1115 precisely engages with the second slot 1122, and the second hook 1121 simultaneously engages with the first slot 1116, forming a two-way interlock. A single hook connection relies on force from only one side, making it prone to loosening with prolonged use or vibration. This double-hook structure, however, uses two sets of opposite-direction engagements, resulting in a larger contact area and more even force distribution, effectively resisting external impacts. For example, bumps during transportation or minor collisions during installation are less likely to cause the lampshade 111 to separate from the lamp holder 112.

[0097] This connection also enhances the sealing performance. After snapping, the hooks and slots fit tightly, reducing gaps and preventing dust and moisture from entering the lamp. This protects components such as the light source board 113 and driver box 160 from corrosion and extends their service life. Furthermore, no tools are required for installation; the snapping can be completed by manual pressing. Disassembly is easy by gently prying open the hooks, facilitating future replacement of the light source or repair of the driver components.

[0098] The number of hooks and slots can be adjusted according to the size of the lamp. For example, three sets are used for small lamps and four sets are used for large lamps. They can be evenly distributed along the circumference. The key is to maintain the cross-interlocking of two sets of "hooks and slots" to ensure a balance between connection stability and ease of operation.

[0099] like Figure 1 and Figure 6 As shown, the lamp also includes a first adjustment button 140 and a second adjustment button 150. A driver box 160 is connected to the light source board 113. Both the first adjustment button 140 and the second adjustment button 150 are connected to the driver box 160.

[0100] In this embodiment, a driver box 160 (with integrated control circuitry and potentiometer) is connected to the light source board 113 in the lamp holder 112. The lamp also includes a first adjustment button 140 and a second adjustment button 150, both of which are directly connected to the driver box 160 via mechanical structures. The rotating shaft of the button is inserted into the rotary switch or potentiometer adjustment hole inside the driver box 160, forming a control link of "button-driver box 160-light source board 113".

[0101] The first adjustment button 140 can be used to adjust the sensing extension time of the sensor module 130: when the user rotates the button, the corresponding potentiometer in the drive box 160 rotates through the rotating shaft, changing the circuit parameters, thereby setting the duration for which the lamp remains lit after sensing human activity (e.g., from a few seconds to a few minutes). This solves the problem of fixed sensing time in traditional lamps. For example, when the user frequently takes items out of the cabinet, the duration can be extended to avoid the lamp being repeatedly switched on and off, improving ease of use.

[0102] The second adjustment button 150 can be used to adjust the sensing brightness threshold: similarly, by rotating another potentiometer inside the drive box 160, the sensitivity of the sensor to ambient light is changed. During the day, when the light inside the cabinet is strong, raising the threshold can prevent the sensor from being falsely triggered due to ambient light interference. At night, when the light is dim, lowering the threshold ensures that the sensor accurately captures human activity, preventing sensor malfunction and perfectly adapting to different usage scenarios under different lighting conditions.

[0103] The direct connection between the two buttons and the driver box 160 ensures zero-delay signal transmission, precise parameter adjustment, and intuitive feedback. Users can sense the adjustment level through changes in resistance when rotating the buttons, completing the setting without additional tools. This structure, in conjunction with the aforementioned height-adjustable sensor and ring lighting system, allows the light fixture to not only adapt to different cabinet layouts but also flexibly adjust its operating mode according to user habits and environmental changes, significantly enhancing the intelligent experience.

[0104] In this embodiment, the connection between the first adjustment button 140, the second adjustment button 150 and the driver box 160 enables flexible adjustment of the sensing parameters through precise mechanical linkage, complementing the structural design and sensing function of the lamp, thereby further improving the adaptability of the lamp and the user experience.
