Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a recessed lamp and a recessed lamp mounting structure. Background Art

[0002] Currently, the light source and heat sink of a recessed light are generally integrated or detachably connected. Furthermore, to ensure effective heat dissipation, a large contact area is required between the heat sink and the heat-conducting surface on the back of the light source. A smaller contact area will affect the heat dissipation effect.

[0003] However, in this design, adjusting the lamp's illumination angle requires rotating both the light source and the heat sink. This requires a significant amount of space for the heat sink to rotate, but this space cannot be effectively used to increase the heat dissipation area, significantly limiting the lamp's angle adjustment. Summary of the Invention

[0004] In view of this, the present invention provides a downlight and a downlight installation structure to solve the problem that the angle adjustment range of the existing downlight is relatively limited when adjusting the angle.

[0005] The present invention provides a recessed lamp, comprising: a heat sink and a lighting assembly, wherein the heat sink has a mounting cavity, the lighting assembly has a hemispherical heat-conducting surface, the heat-conducting surface is rotatably embedded in the mounting cavity, a sealing damping structure is provided between the heat-conducting surface and the mounting cavity, and a heat-conducting medium is filled between the heat-conducting surface and the mounting cavity. In this technical solution, the lighting assembly is pivotally connected to the radiator, and the radiator's position is fixed. Therefore, when adjusting the angle, only the lighting assembly needs to be adjusted; the radiator's position remains unchanged. This arrangement eliminates the need to reserve additional space for the radiator's rotation during installation. This design effectively reduces the required slotting required for recessed lighting installations, such as in ceilings.

[0006] Furthermore, the sealed damping structure of the present invention allows the lighting assembly to maintain a stable angle regardless of its adjustment. Furthermore, by filling the heat-conducting medium, the contact area between the lighting assembly's heat-conducting surface and the heat sink is increased, resulting in more uniform and faster heat dissipation.

[0007] Furthermore, due to the hemispherical heat-conducting surface design, the heat-conducting surface has a large rotation angle, and since there is no need to reserve additional space for the radiator during rotation, the rotation angle of the lighting component is not limited by the position of the radiator, and the rotation to either side can reach 40-60°.

[0008] The mounting cavity is formed with a recess at one end thereof facing the lighting assembly, the recess corresponding to the maximum rotation angle of the lighting assembly. By setting the recess, when the lighting assembly rotates within the rotation range, the side light can be emitted through the recess, so that the light is not blocked.

[0009] Optionally, the radiator has heat dissipation fins, and the ratio of the heat dissipation area of ​​the heat dissipation fins to the wattage of the lighting assembly is ≤30-40 square centimeters per watt.

[0010] Optionally, the lighting assembly is rotationally connected to the heat sink via an axis structure.

[0011] In the above scheme, when the lighting assembly rotates around the axis, the axis structure can evenly share the weight of the lighting assembly and the various forces generated during the rotation process, thereby ensuring the stability of the lighting assembly during the rotation process, making it less likely to shake or deviate, and making the adjustment of the lighting angle more accurate and reliable.

[0012] Optionally, the sealing and damping structure includes: an annular groove, the annular groove is arranged inside the installation cavity, a sealing ring is embedded in the annular groove, and the sealing ring abuts against the heat conducting surface.

[0013] In this solution, an annular groove is provided within the mounting cavity, and a sealing ring is placed therein. The sealing ring closely adheres to the heat-conducting surface of the lighting assembly, effectively preventing leakage of the heat-conducting medium (e.g., liquid) within the mounting cavity. When the lighting assembly is rotated to adjust its angle, the heat-conducting surface slides against the sealing ring, maintaining a consistent seal. The sealing ring also dampens the lighting assembly, maintaining the adjusted angle and preventing relative movement due to gravity or other factors.

[0014] Optionally, the ring thickness of the annular groove at a side away from the lighting assembly is greater than the ring thickness at a side close to the lighting assembly.

[0015] In this solution, the annular groove is thicker on the side away from the lighting assembly, providing more stable support for the sealing ring. When the lighting assembly rotates, the sealing ring is subjected to friction from the heat-conducting surface. The thicker side can better resist these forces, preventing the sealing ring from excessive deformation, displacement, or extrusion under stress.

[0016] Optionally, the inner ring surfaces of the annular walls on both sides of the annular groove are respectively provided with chamfers, which gradually reduce the ring thickness of the heat sink in the direction of the lighting component. This arrangement allows a smaller gap to be maintained between the chamfered surface of the chamfer and the heat-conducting surface of the lighting component. The smaller gap allows the sealing ring to fit more closely to the heat-conducting surface after installation, reducing the channel for liquid leakage. When the lighting component rotates, the sealing ring can better maintain a sealed state in this relatively tight space, effectively preventing liquid from leaking out of the installation cavity. Even when the lighting angle is frequently adjusted or subjected to a certain degree of vibration, this design can ensure the sealing of the heat dissipation system and guarantee its stable operation.

[0017] Optionally, the heat sink includes a main body portion and a connecting portion, the main body portion and the connecting portion are detachably connected, and the annular groove is formed between the main body portion and the connecting portion.

[0018] In the above solution, the heat sink is divided into a main body and a connecting portion, with the annular groove formed between the two. This design simplifies the manufacturing process, allowing each component to be manufactured using the most suitable process, improving production efficiency and reducing manufacturing costs. Furthermore, placing the annular groove between the two components reduces manufacturing complexity compared to machining complex annular grooves on a single component, which helps ensure consistent product quality.

[0019] Optionally, the end of the connecting portion facing the lighting assembly has a supporting ring extending radially inward, the main body is inserted into the connecting portion, and a gap is maintained between the end of the main body and the supporting ring to form the annular groove.

[0020] In the above solution, the annular groove is formed by the spacing between the end of the main body and the support ring. This structure helps optimize the installation and sealing performance of the sealing ring within the groove. The sealing ring is installed in the groove, and the support ring provides stable support for the sealing ring, preventing it from shifting or deforming during the rotation of the lighting assembly. Furthermore, the uniform spacing between the main body and the support ring ensures a tight fit between the sealing ring and the heat-conducting surface of the lighting assembly, effectively preventing liquid leakage within the installation cavity.

[0021] Optionally, one end of the lighting component embedded in the installation cavity has a first wiring hole, and the heat sink has a second wiring hole, one end of the second wiring hole is connected to the installation cavity, and the other end is connected to the outside world, and the first wiring hole and the second wiring hole respectively have a glue sealing structure.

[0022] In this solution, the lighting assembly's first wiring hole and the heat sink's second wiring hole provide a routing channel for electrical wiring, allowing wires from the lighting assembly to the external power supply or control system to pass smoothly. The adhesive seal creates a good seal at the wiring holes, ensuring that liquids within the mounting cavity do not leak through the wiring holes.

[0023] Optionally, the device further includes a dough ring that is removably connected to the end of the heat sink connected to the lighting assembly. The dough ring can be designed in various shapes, colors, and materials to suit various interior decoration styles. Installed on the end of the heat sink connected to the lighting assembly, the dough ring provides a protective shield, shielding the connection between the heat sink and the lighting assembly from dust and debris, protecting the internal structure from environmental damage.

[0024] Optionally, the dough ring and the radiator are connected by snapping.

[0025] The present invention further provides a recessed lamp installation structure, comprising: a mounting surface, wherein a mounting groove is provided on the mounting surface, and the recessed lamp according to any one of the above-mentioned solutions is embedded in the mounting groove; The top surface of the mounting groove is matched with the top surface of the heat sink of the recessed lamp, and / or at least one inner side wall of the mounting groove is matched with the outer side wall of the heat sink of the recessed lamp.

[0026] In the above solution, the mounting slot aperture is matched to the downlight heat sink, ensuring the downlight fits snugly within the slot. This precise dimensional fit provides a stable mounting base for the downlight, reducing any potential wobbling or shifting during use. The heat transfer surface offers a wide rotation angle, and since no additional space is required for the heat sink during rotation, the lighting assembly's rotation angle is not limited by the heat sink's position, allowing for 40-60° rotation in either direction.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] like Figure 1 、 Figure 3 As shown, a specific implementation of the recessed light provided in this embodiment includes: a heat sink 1 and a lighting assembly 2, wherein the lighting assembly 2 is rotatably connected to the heat sink 1. Specifically, the heat sink 1 has a mounting cavity 5, and the lighting assembly 2 has a hemispherical heat-conducting surface that is rotatably embedded in the mounting cavity 5. A sealing damping structure is provided between the heat-conducting surface and the mounting cavity, and the space between the heat-conducting surface and the mounting cavity is filled with a heat-conducting medium. Specifically, the heat-conducting medium may include: a liquid (such as water), a thermally conductive gel, a thermally conductive mud, etc. The recessed light provided in this embodiment is pivotally connected to the heat sink 1 via the lighting assembly 2, which maintains a fixed position. Therefore, when adjusting the angle, only the lighting assembly 2 needs to be adjusted; the position of the heat sink 1 remains unchanged. This arrangement eliminates the need to reserve additional space for the heat sink 1 to rotate during installation. This design effectively reduces the required slotting required for recessed light installation, typically in the ceiling or other mounting surfaces.

[0035] Furthermore, the sealed damping structure of this technical solution allows the lighting assembly to maintain a stable angle regardless of its adjustment. Furthermore, by filling the heat-conducting medium, the contact area between the lighting assembly's heat-conducting surface and the heat sink is increased, resulting in more uniform and faster heat dissipation.

[0036] Due to the hemispherical heat-conducting surface design, the heat-conducting surface has a large rotation angle, and since no additional space is required for the radiator to rotate during the rotation process, the rotation angle of the lighting component is not limited by the position of the radiator, and the rotation to either side can reach 40-60°.

[0037] like Figure 1 、 Figure 2 As shown, in this embodiment, a recess is formed at one end of the mounting cavity toward the lighting assembly, and the recess corresponds to the maximum rotation angle of the lighting assembly. In other words, during the rotation of the lighting assembly, the recess is always located outside the lighting area of ​​the lighting assembly.

[0038] Specifically, the end of the heat sink facing the lighting assembly has two connecting arms extending toward the lighting assembly, the two connecting arms are symmetrically arranged, and the lighting assembly is rotatably connected via the two connecting arms. A recess is formed between the two connecting arms, and the recess is arc-shaped.

[0039] By providing the recess, when the lighting assembly rotates within the rotation range, the side light can be emitted through the recess, so that the light will not be blocked.

[0040] like Figure 2 As shown, in the downlight provided in this embodiment, the heat sink has cooling fins, and the ratio of the heat dissipation area of ​​the cooling fins to the wattage of the lighting assembly is ≤30-40 square centimeters per watt. Specifically, the heat sink can be made of aluminum, further preferably an Al-Si-Cu alloy, such as a die-cast aluminum alloy.

[0041] In the prior art, LED lamps generally require a heat dissipation area of ​​50-60 square centimeters per watt. The recessed lamp provided in this embodiment reduces the heat dissipation area by filling it with a thermally conductive medium without affecting the heat dissipation effect, thereby reducing the overall volume and making it easier to install.

[0042] like Figure 2 As shown, in this embodiment, the lighting assembly 2 is rotationally connected to the radiator 1 via the shaft structure 4. Specifically, the radiator 1 has a connecting arm 3 extending toward the lighting assembly 2, and the connecting arm 3 has two symmetrically arranged shaft structures 4. In other words, two symmetrical shaft structures 4 are provided on the connecting arm 3 of the radiator 1 to provide stable and balanced rotation support for the lighting assembly 2. With such an arrangement, when the lighting assembly 2 rotates around the axis, the symmetrical shaft structures 4 can evenly share the weight of the lighting assembly 2 and the various forces generated during the rotation process, thereby ensuring the stability of the lighting assembly 2 during the rotation process, making it less likely to shake or deflect, and making the adjustment of the lighting angle more precise and reliable.

[0043] like Figure 2、 Figure 3 and Figure 4 As shown, in some embodiments, an annular groove is provided at the opening of the mounting cavity 5, and a sealing ring 7 is disposed within the annular groove, abutting the sealing ring 7 against the heat-conducting surface 6. After assembly, the sealing ring 7 is tightly attached to the heat-conducting surface 6 of the lighting assembly 2, effectively preventing liquid leakage within the mounting cavity 5. When the lighting assembly 2 is rotated to adjust the angle, the heat-conducting surface 6 slides relative to the sealing ring 7, and the sealing ring 7 can maintain a constant sealing effect. The sealing ring 7 also provides damping for the lighting assembly, allowing it to maintain the adjusted angle and prevent relative movement due to gravity or other factors.

[0044] In addition, in some alternative embodiments, the sealing and damping structure between the lighting assembly 2 and the mounting cavity 5 may also adopt other forms.

[0045] like Figure 4 As shown, the ring thickness of the annular groove on the side away from the lighting component 2 is greater than the ring thickness on the side close to the lighting component 2. Specifically, the side of the annular groove away from the lighting component 2 can be called the first annular wall 8, and the side of the annular groove close to the lighting component 2 can be called the second annular wall 9. In this embodiment, the thickness of the first annular wall 8 is relatively large, and such a configuration provides a more stable support for the sealing ring 7. When the lighting component 2 rotates, the sealing ring 7 will be subjected to friction from the heat-conducting surface 6. The thicker first annular wall 8 can better resist these forces, preventing the sealing ring 7 from excessive deformation, displacement or extrusion when subjected to force.

[0046] Of course, the above description is not restrictive. In some alternative embodiments, the thickness of the first annular wall 8 and the second annular wall 9 may be equal.

[0047] like Figure 4 As shown, in this embodiment, the inner surfaces of the annular walls on both sides of the annular groove each have chamfers. These chamfers gradually reduce the ring thickness of the heat sink 1 toward the lighting assembly 2. In other words, the inner surfaces of the first annular wall 8 and the second annular wall 9 each have chamfers. These chamfers gradually reduce the ring thickness of the heat sink 1 toward the lighting assembly 2. This arrangement maintains a small and uniform gap between the chamfered surface 10 and the heat transfer surface 6 of the lighting assembly 2. This uniform, small gap allows the sealing ring 7 to fit more closely to the heat transfer surface 6 after installation, reducing the path for liquid leakage. When the lighting assembly 2 rotates, the sealing ring 7 can better maintain a sealed state within this relatively tight space, effectively preventing liquid from leaking out of the installation cavity 5. Even when the lighting angle is frequently adjusted or subjected to certain vibrations, this design ensures the sealing of the heat dissipation system and guarantees its stable operation.

[0048] It should be noted that the chamfers may be rounded or beveled in some alternative embodiments.

[0049] like Figure 5 As shown, in some embodiments, the heat sink 1 includes a main body 11 and a connecting portion 12, wherein the main body 11 and the connecting portion 12 are detachably connected, and the annular groove is formed between the main body 11 and the connecting portion 12. By providing the annular groove between the main body 11 and the connecting portion 12, the manufacturing difficulty is reduced compared to machining a complex annular groove on a single component, which helps to ensure the consistency of product quality.

[0050] In addition, in the above solution, the heat sink 1 is divided into a main body portion 11 and a connecting portion 12, and an annular groove is formed between the two. This design simplifies the manufacturing process, allowing each component to be manufactured using the most suitable process, thereby improving production efficiency and reducing manufacturing costs.

[0051] Of course, the above description is not restrictive. In some alternative embodiments, the heat sink 1 can be integrally formed, and the annular groove is machined and formed in the heat sink 1 . like Figure 6 As shown, in some embodiments, the end of the connecting portion 12 facing one end of the lighting assembly 2 has a supporting ring 13 extending radially inward, the main body 11 is inserted into the connecting portion 12, and the end of the main body 11 and the supporting ring 13 are spaced apart to form the annular groove. This structure helps to optimize the installation and sealing performance of the sealing ring 7 in the groove. The sealing ring 7 is installed in the groove, and the supporting ring 13 can provide stable support for the sealing ring 7 to prevent the sealing ring 7 from shifting or deforming during the rotation of the lighting assembly 2. At the same time, the uniform spacing between the main body 11 and the supporting ring 13 ensures that the sealing ring 7 fits tightly against the heat-conducting surface 6 of the lighting assembly 2, effectively preventing liquid leakage in the installation cavity 5.

[0052] In addition, in some alternative embodiments, the connecting portion 12 may also be inserted into the main body 11 , so that the annular groove is formed between the end of the connecting portion 12 and the interior of the main body 11 .

[0053] It should be noted that, in this embodiment, the connection portion 12 and the main body 11 are connected by a threaded structure. In addition, in some alternative embodiments, the connection portion 12 and the main body 11 may also be connected by other means, such as a snap connection.

[0054] like Figure 3As shown, in some embodiments, the end of the lighting assembly 2 embedded in the installation cavity 5 has a first wiring hole 14, and the heat sink 1 has a second wiring hole 15. One end of the second wiring hole 15 is connected to the installation cavity 5, and the other end is connected to the outside world. The first wiring hole 14 and the second wiring hole 15 are respectively provided with a glue sealing structure. In the above scheme, the first wiring hole 14 of the lighting assembly 2 and the second wiring hole 15 of the heat sink 1 provide a wiring channel for the electrical circuit, so that the wires from the inside of the lighting assembly 2 to the external power supply or control system can pass smoothly. The glue sealing structure forms a good seal at the wiring hole, ensuring that the liquid in the installation cavity 5 will not leak to the outside world along the wiring hole.

[0055] Of course, the above description is not restrictive, and in some alternative embodiments, the first wiring hole 14 and the second wiring hole 15 can be omitted. The external power supply can be electrically connected to the lighting assembly 2 from other locations.

[0056] like Figure 7 As shown, some embodiments further include a dough ring 16. The dough ring 16 is detachably connected to the end of the radiator 1 connected to the lighting assembly 2. Installed on the end of the radiator 1 connected to the lighting assembly 2, the dough ring 16 provides a protective function. Furthermore, the dough ring 16 can be designed in various shapes, colors, and materials to suit various interior decoration styles. The dough ring 16 also shields the connection portion 12 between the radiator 1 and the lighting assembly 2, preventing dust and debris from entering and protecting the internal structure from external environmental erosion.

[0057] like Figure 8 、 Figure 9 and Figure 10 As shown, in this embodiment, the dough ring 16 is connected to the heat sink 1 via a snap-fit ​​connection. Specifically, the mounting side of the dough ring 16 has a plurality of snaps 17 spaced apart around its circumference, and the heat sink 1 has an annular groove 18 that engages with the snaps 17. During installation, the snap-fit ​​connection of the dough ring 16 is achieved by pushing the snaps 17 of the dough ring 16 into the annular groove 18.

[0058] Of course, the above description is not restrictive, and in some alternative embodiments, the ring 16 and the radiator 1 may be detachably connected in other ways, such as by a threaded structure.

[0059] Working principle: In the recessed light provided in this embodiment, the lighting assembly 2 is rotatably connected to the radiator 1 via an axis structure 4 (or other connection form). The position of the radiator 1 is fixed, and only the angle of the lighting assembly 2 needs to be adjusted. During installation, there is no need to reserve rotation space for the radiator 1, which can reduce the groove area on the installation surface such as the ceiling.

[0060] The mounting cavity 5 within the heat sink 1 is in sliding, sealed contact with the lighting assembly 2. The liquid within the cavity 5 utilizes its high specific heat capacity to absorb heat generated by the lighting assembly 2, achieving efficient heat exchange through heat conduction and convection. The sealing and damping structure between the lighting assembly 2 and the cavity 5 (e.g., the seal 7 and heat-conducting surface 6) ensures that the liquid does not leak during rotational adjustment.

[0061] Multiple sealing features ensure fluid leakage between the lighting assembly 2 and the mounting cavity 5. For example, the sealing ring 7 within the annular groove abuts the heat-conducting surface 6 of the lighting assembly 2. The structural design of the annular groove (such as the thickness difference between the two annular walls and the chamfered inner surface) enhances the support and sealing effect of the sealing ring 7. The structural arrangement of the heat sink 1's main body 11 and connecting portion 12 (such as the annular groove formed between the support ring 13 and the end of the main body 11) also optimizes the installation and sealing performance of the sealing ring 7.

[0062] The first wiring hole 14 of the lighting assembly 2 and the second wiring hole 15 of the heat sink 1 provide passages for the wires, and the glue sealing structure prevents the liquid in the installation cavity 5 from leaking along the wiring holes.

[0063] like Figure 11 、 Figure 12 and Figure 13 As shown, an embodiment of the present invention further provides a recessed lamp installation structure, comprising: a mounting surface, a mounting groove being provided on the mounting surface, and the recessed lamp described in the above solution being embedded in the mounting groove.

[0064] In some embodiments, the top surface of the mounting groove is adapted to the top surface of the radiator of the recessed light. It should be noted that the adaptation mentioned here means that the top surface of the radiator of the recessed light is close to or in contact with the top surface of the mounting groove. In some installation environments with low roofs, the recessed light provided in this embodiment can bring the top surface of the radiator closer to the top surface of the mounting groove, thereby saving installation space. When adjusting the angle of the lighting component of the recessed light, since there is no need to rotate the radiator, there is no need to consider the rotation space at the top of the radiator. Therefore, setting it closer to the top surface of the groove does not affect the use of the recessed light.

[0065] In some embodiments, at least one inner side wall of the mounting groove is adapted to the outer side wall of the heat sink 1 of the recessed light. It should be noted that the adaptation mentioned here means that the outer side wall of the heat sink is close to or in contact with at least one inner side wall in the mounting groove. This arrangement ensures that the recessed light can be installed closer to the edge of the wall, thereby meeting the needs of users. In this embodiment, when adjusting the angle of the lighting component of the recessed light, since there is no need to rotate the radiator, there is no need to consider the rotation space around the radiator. Therefore, when it is set closer to the edge of the wall, it does not affect the use of the recessed light.

[0066] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall all fall within the scope defined by the present invention.
