Description

Technical Field

[0001] This utility model relates to the technical field of lighting devices, and more specifically, to a downlight. Background Technology

[0002] In existing technologies, lighting fixtures, especially spotlights and downlights, often employ a rotating ring structure on the outside of the lamp body to achieve adjustable beam angle. In this structure, the face ring (i.e., the decorative ring at the front of the lamp, which has an anti-glare function) and the rotating ring adjust the beam direction through rotation. However, this design has some significant limitations. First, a certain clearance space must be formed between the rotating ring and the lamp body to ensure relative rotation. This not only limits the range of rotation angle, resulting in limited beam angle adjustment, but also increases the overall size of the lamp, occupying additional installation space. For lamps installed in narrow environments or with specific decorative requirements, this is a significant drawback.

[0003] Secondly, another common method of light source adjustment involves incorporating a structure within the lamp body that allows the light source and lens to rotate synchronously. This aims to reduce the external space occupied by the rotating ring, resulting in a more compact lamp design. However, this design also requires a clearance between the light source and the lamp body to ensure the light source can rotate freely. This clearance, however, becomes a new source of problems. It creates unintended light leakage paths, causing light to escape from the gap, producing stray light and affecting the lighting effect and the aesthetics of the lamp. This problem is particularly pronounced with the application of high-brightness LED light sources, potentially causing visual discomfort and reducing user satisfaction.

[0004] As can be seen from the above, current adjustable-angle downlights have the problems of increased space occupation and light leakage. Utility Model Content

[0005] The main objective of this invention is to provide a downlight that solves the problems of increased space occupation and light leakage in existing adjustable-angle downlights.

[0006] To achieve the above objectives, according to one aspect of the present invention, a downlight is provided. The downlight includes a cylindrical body, a light source assembly, an adjustment assembly, and a lens. The light source assembly is fixedly disposed at the first end of the cylindrical body. The adjustment assembly is disposed inside the cylindrical body and includes a rotating part rotatably disposed inside the cylindrical body. The rotating part has a light-passing channel. The lens is disposed on the rotating part and rotates with the rotating part. Along the axial direction of the cylindrical body, the lens is disposed at the second end of the cylindrical body relative to the light source assembly. At least a portion of the lens is disposed inside the light-passing channel. The light from the light source assembly exits the cylindrical body after passing through the lens inside the light-passing channel.

[0007] Furthermore, the rotating part has a direct-light position and a deviated position that can be switched by rotation. When the rotating part is in the direct-light position, the light channel is coaxial with the cylinder body; when the rotating part is in the deviated position, the axis of the light channel intersects with the axis of the cylinder body.

[0008] Furthermore, the downlight also includes a heat sink, which is disposed at the first end of the downlight body. The heat sink has a mounting protrusion extending toward the second end of the downlight body. The end of the mounting protrusion extends into the interior of the light channel, and the light source assembly is disposed at the end of the mounting protrusion.

[0009] Furthermore, the diameter of the mounting protrusion is smaller than the diameter of the light-passing channel, and an active space is formed between the outer peripheral surface of the mounting protrusion and the inner wall surface of the light-passing channel; and / or the heat sink has an annular groove provided on the outer peripheral side of the mounting protrusion, and when the rotating part rotates, the end of the rotating part facing the first end of the cylinder can extend into the annular groove, which is used to provide clearance.

[0010] Furthermore, the downlight also includes a fixing ring, which is fixedly disposed at the end of the rotating part away from the first end of the cylinder. The first end of the fixing ring is disposed inside the light passage. The inner wall surface of the light passage has a rib. Along the axial direction of the cylinder, the rib and the first end of the fixing ring form a clamping space. The peripheral edge of the light-emitting side of the lens is clamped and fixed inside the clamping space.

[0011] Furthermore, the ribs are formed as a ring structure; or the ribs are formed as at least one arc segment, and when multiple arc segments are provided, the multiple ribs are spaced apart along the circumference of the light channel.

[0012] Furthermore, the outer periphery of the second end of the fixing ring has a flange structure facing away from the axis of the cylinder, and the flange structure abuts against the end face of the first end of the rotating part away from the cylinder; the outer periphery of the first end of the fixing ring has at least one slot, and the inner wall of the light passage has a snap-fit ​​protrusion that engages with the slot; when multiple slots are provided, the multiple slots are spaced apart along the circumference of the fixing ring.

[0013] Furthermore, the outer surface of the rotating part is a first spherical surface, and the adjustment assembly also includes a ring-shaped fixing frame, which is disposed on the inner wall surface of the cylinder. The rotating part is rotatably disposed on the fixing frame, and the inner wall surface of the fixing frame is a second spherical surface that slides with the outer surface of the rotating part. A damping structure is disposed on the fixing frame and abuts against the outer surface of the rotating part to provide damping.

[0014] Furthermore, the fixing frame includes a first frame and a second frame that are detachably connected along the axial direction of the cylinder. Both the first frame and the second frame are provided with multiple damping structures spaced apart along the circumference of the fixing frame. The damping structures on the first frame and the second frame are alternately arranged along the circumference of the fixing frame.

[0015] Furthermore, the damping structure is a positioning bead, and the inner wall of the fixing frame has a mounting groove with an opening facing the rotating part. At least a portion of the positioning bead is disposed inside the mounting groove, and the ball of the positioning bead abuts against and rolls against the outer surface of the rotating part; or the damping structure includes an elastic arm and a spherical protrusion, the first end of the elastic arm is disposed in the fixing frame, the spherical protrusion is disposed in the second end of the elastic arm, and the spherical protrusion abuts against and slides against the outer surface of the rotating part.

[0016] Furthermore, when the damping structure includes elastic arms and spherical protrusions, multiple damping structures are provided. The extension directions of two adjacent elastic arms are opposite. Along the circumference of the fixed frame, the fixed frame has multiple notches. The second end of one of the two adjacent elastic arms is arranged opposite to the notch and can deform toward the inside of the notch. Along the axial direction of the cylinder, the second end of the other elastic arm of the two adjacent elastic arms extends to the outside of the fixed frame and can deform toward the side away from the rotating part.

[0017] Furthermore, the downlight also includes a face ring disposed at the second end of the tube body, the face ring being coaxially disposed with the tube body, and the face ring having a flared structure along the direction from the first end of the tube body toward the second end; and / or the light-inlet end of the face ring being at least partially connected to the light-outlet end of the light-passing channel.

[0018] By applying the technical solution of this utility model, the light source component of the downlight of this application is fixedly installed on the cylinder body. The direction of light emission is adjusted by driving the lens to rotate through the rotating part installed inside the cylinder body. The downlight of this application has a simple and compact structure. By utilizing the linkage between the adjustment component inside the cylinder body and the lens, stepless adjustment of the light source component can be achieved, which not only reduces the space occupied for installation, but also eliminates the phenomenon of light leakage at the end of the cylinder body.

[0019] The downlight of this application uses a light source component fixedly installed in the cylinder body to form an integral structure between the light source component and the cylinder body. This avoids light leakage and scattering during the adjustment of the light angle, which helps to ensure the stability and purity of the light generated by the power supply component. At the same time, this application only requires operating the position of the adjustment component inside the cylinder body to adjust the angle of the light, making the overall operation simple and improving the user experience.

[0033] To address the issues of increased space occupation and light leakage in existing adjustable-angle downlights, this invention provides a new type of downlight.

[0034] Among them, the downlights are downlights with adjustable beam angles.

[0035] like Figures 1 to 7 As shown, the downlight includes a cylindrical body 10, a light source assembly 20, an adjustment assembly 30, a face ring 70, and a lens 40. The first and second ends of the cylindrical body 10 are formed into an open cylindrical structure. The light source assembly 20 is fixedly disposed at the first end of the cylindrical body 10. The adjustment assembly 30 is disposed inside the cylindrical body 10. The adjustment assembly 30 includes a rotating part 310 rotatably disposed inside the cylindrical body 10. The rotating part 310 has a light passage 311. The lens 40 is disposed on the rotating part 310 and rotates with the rotating part 310. Along the axial direction of the cylindrical body 10, the lens 40 is disposed relative to the light source assembly 20 near the second end of the cylindrical body 10. At least a portion of the lens 40 is disposed inside the light passage 311. The light passage 311 is opposite to the light path of the light source assembly 20. The lens 40 inside the light passage 311 can precisely control the beam angle of the downlight. The light from the light source assembly 20 is emitted from the cylindrical body 10 after passing through the lens 40 inside the light passage 311. The face ring 70 is disposed at the second end of the cylindrical body 10.

[0036] The rotating part 310 is a omnidirectional ball with a first spherical surface on its outer surface. A light channel 311 is provided on the omnidirectional ball. By rotating the omnidirectional ball in multiple directions, the angle adjustment of the emitted light can be realized in multiple angles and directions.

[0037] Specifically, the light source assembly 20 of the downlight of this application is fixedly mounted on the cylindrical body 10. The rotation part 310 inside the cylindrical body 10 drives the lens 40 to rotate, thereby adjusting the direction of light emission. The downlight of this application has a simple and compact structure. By utilizing the linkage between the adjustment assembly 30 inside the cylindrical body 10 and the lens 40, stepless adjustment of the light from the light source assembly 20 can be achieved. This not only reduces the space occupied during installation but also eliminates the phenomenon of light leakage at the end of the cylindrical body 10.

[0038] The rotating part 310 rotates the lens 40 accordingly. During the use of the downlight, the rotating part 310 has a direct beam position and an off-center position that can be switched by rotation. When the rotating part 310 is in the direct beam position, the light channel 311 is coaxial with the downlight body 10, and the light shines directly along the axis of the light channel 311. When the rotating part 310 is in the off-center position, the axis of the light channel 311 intersects with the axis of the downlight body 10. Specifically, there are multiple off-center positions. These multiple off-center positions can be adjusted according to the rotation angle of the rotating part 310. The light emission direction and angle corresponding to different off-center positions are different, so as to achieve adaptive light angle adjustment according to the application scenario.

[0039] In this embodiment, the lens 40 is fixedly connected to the rotating part 310, and the light source assembly 20 is fixedly connected to the cylinder 10. When the rotating part 310 rotates inside the cylinder 10, the lens 40 switches positions relative to the light source assembly 20. When the rotating part 310 is in a deviated position, the relative positions of the lens 40 and the light source assembly 20 change. The light emitted by the light source assembly 20 enters the light-inlet side of the lens 40 and exits from the light-outlet side. The lens 40 can change the exit angle of the light, thereby adjusting the irradiation direction of the light beam.

[0040] In this embodiment, the face ring 70 is coaxially arranged with the cylinder 10 and is formed with a flared structure along the direction from the first end to the second end of the cylinder 10. The face ring 70 is disposed on the light-emitting side of the light-passing channel 311. The light inside the light-passing channel 311 is directed toward the face ring 70. The face ring 70 with the flared structure adopted in this application is beneficial to improving the light emission range. In addition, during the rotation of the rotating part 310, the light-passing channel 311 always remains connected to the light-inlet end of the face ring 70, thereby ensuring that the light can enter the face ring 70 and be emitted from the inside of the face ring 70 to the outside of the cylinder 10.

[0041] like Figure 2 and Figure 3 As shown, the light source assembly 20 is fixedly mounted on the cylinder 10 via a heat sink 50. The heat sink 50 is fixedly mounted on the first end of the cylinder 10 and blocks the opening at the first end, ensuring that light is emitted from the second end of the cylinder 10 on one side, thus avoiding light leakage caused by light being emitted from both ends of the cylinder 10.

[0042] Specifically, by placing the light source assembly 20 on the heat sink 50, the structure of the heat sink 50 is not only rationally utilized for installation, but also facilitates the heat dissipation of the light source assembly 20. As the main heat-generating component of the cylinder 10, fixing the light source assembly 20 on the heat sink 50 helps to improve heat dissipation efficiency and ensure the stability of the downlight's use.

[0043] In this application, the light source assembly 20 is fixed to the portion of the heat sink 50 located inside the cylinder 10, thereby emitting light to the second end of the cylinder 10. The arrangement of the heat sink 50 enables the cylinder 10 to form a structure that emits light from one side. Compared with the structure in the prior art where the light source rotates with the lens 40, this avoids the phenomenon of light leakage in the cylinder 10 due to the existence of clearance gap between the cylinder 10 and the light source assembly 20.

[0044] The heat sink 50 has a mounting protrusion extending toward the second end of the cylinder 10. The end of the mounting protrusion extends into the interior of the light channel 311. The light source assembly 20 is fixedly disposed at the end of the mounting protrusion so that the light source assembly 20 is fixedly disposed inside the cylinder 10.

[0045] The heat sink 50 of this application has multiple heat dissipation ribs on the end face opposite to the light source assembly 20. The multiple heat dissipation ribs are arranged at intervals along the circumference of the cylinder 10. By setting multiple heat dissipation ribs, the contact area with the atmosphere is increased, thereby improving the heat dissipation efficiency of the heat sink 50.

[0046] In this embodiment, the mounting protrusion is a cylindrical protrusion and is coaxially arranged with the cylinder 10, that is, the distance between the light source assembly 20 and the inner wall of the cylinder 10 is the same, which is conducive to achieving uniformity of light from the light source assembly 20 inside the cylinder 10.

[0047] The light-passing channel 311 of this application is a cylindrical channel. The diameter of the mounting protrusion is smaller than the diameter of the light-passing channel 311. An active space is formed between the outer peripheral surface of the mounting protrusion and the inner wall surface of the light-passing channel 311. During the rotation switching between the direct position and the off-center position, the rotating part 310 can undergo relative displacement with the mounting protrusion. The active space is set to form an internal clearance space for the rotating part 310.

[0048] In this embodiment, the heat sink 50 has an annular groove 510 disposed on the outer peripheral side of the mounting protrusion. When the rotating part 310 rotates, the end of the rotating part 310 facing the first end of the cylinder 10 can extend into the annular groove 510. During the rotation switching between the direct position and the offset position, the annular groove 510 is used to provide clearance and forms a clearance space outside the rotating part 310. When the rotating part 310 switches to the offset position, the end of the rotating part 310 extends into the interior of the annular groove 510. At this time, it is beneficial for the heat sink 50 to dissipate heat from the rotating part 310, thereby improving the heat dissipation efficiency of the downlight.

[0049] This application uses the movable space between the rotating part 310 and the mounting protrusion to form the internal clearance of the rotating part 310, and the annular groove 510 on the heat sink 50 to form the external clearance on the rotating part 310. The structure of the internal clearance and the external clearance together ensures the stable rotation of the rotating part 310 inside the cylinder 10, thereby realizing the angle adjustment of light through the linkage of the rotating part 310 and the lens 40.

[0050] In this embodiment, the light source assembly 20 includes a bracket and a lamp body. The bracket is fixedly disposed on the protruding end of the mounting protrusion and forms a mounting cavity between the bracket and the end face of the protruding end. The bracket has a light-passing port communicating with the mounting cavity. The lamp body is disposed inside the mounting cavity and emits light toward the light-passing port.

[0051] The lamp body is an LED lamp bead, and the bracket is a frame structure. A rectangular light-passing opening is formed on the side of the frame away from the end face of the protruding end. The bracket can be fixed to the end face of the protruding end by a buckle or by fasteners such as bolts. The lamp body is clamped between the end face of the protruding end and the bracket to fix it to the heat sink 50.

[0052] like Figure 3 As shown, the lens 40 and the light source assembly 20 are spaced apart along the axial direction of the light passage 311, and the lens 40 is disposed inside the light passage 311. The lens 40 covers the emission path of the light, and the light emitted by the light source assembly 20 enters the light passage 311 and is emitted out through the lens 40.

[0053] The shape and material of the lens 40 are selected according to the desired lighting effect, such as a spherical lens 40, an aspherical lens 40, or a plastic or glass material.

[0054] Specifically, the lens 40 is located near the light-emitting end of the light-passing channel 311. The downlight also includes a fixing ring 60, which is fixedly disposed at the end of the rotating part 310 away from the first end of the cylinder 10. The first end of the fixing ring 60 is disposed inside the light-passing channel 311. The inner wall surface of the light-passing channel 311 has a rib 312. Along the axial direction of the cylinder 10, a clamping space is formed between the rib 312 and the first end of the fixing ring 60. The peripheral edge of the light-emitting side of the lens 40 is clamped and fixed inside the clamping space.

[0055] The fixing ring 60 is fixedly connected to the rotating part 310 and is used to fix the lens 40. The fixing ring 60 ensures the stability of the lens 40 during the rotation of the rotating part 310, and avoids the problem of the lens 40 moving along the axial direction of the light channel 311, which would affect the light emission effect.

[0056] In this application, the rib 312 can be a circular structure to form a ring support arranged circumferentially along the light passage 311, that is, the rib 312 forms a ring support surface to support the lens 40; the rib 312 in this application can also be one or more arc segments. When one arc segment is provided, the arc segment is preferably an arc segment with a central angle greater than 180°, which helps to ensure the stability of the lens 40. When multiple arc segments are provided, multiple ribs 312 are arranged at intervals along the circumferential direction of the light passage 311, and multiple arc segments form multiple support points arranged circumferentially. The arrangement of multiple support points forms multi-point support for the lens 40, thereby realizing the stable fixing of the lens 40 inside the light passage 311.

[0057] In this embodiment, the outer periphery of the second end of the fixing ring 60 has a flange structure 620 disposed on the side away from the axis of the cylinder 10. The flange structure 620 abuts against the end face of the first end of the rotating part 310 away from the cylinder 10. The outer periphery of the first end of the fixing ring 60 has at least one slot 610. The inner wall of the light passage 311 has a snap-fit ​​protrusion that engages with the slot 610. When multiple slots 610 are provided, the multiple slots 610 are spaced apart along the circumference of the fixing ring 60.

[0058] The fixing ring 60 is fixed to the rotating part 310 by abutting its second end against the rotating part 310 and snapping its first end against the rotating part 310. The flange structure 620 is designed to achieve a face-to-face contact and abutment with the rotating part 310, ensuring the sealing of the connection area between the fixing ring 60 and the rotating part 310 and the installation strength of the fixing ring 60. The fixing ring 60 is fixed to the rotating part 310 by a snap-fit ​​method, which facilitates the installation and removal of the fixing ring 60 and improves the assembly efficiency of the downlight.

[0059] Specifically, the latching protrusions and the latching slots 610 are arranged in a one-to-one correspondence, and multiple latching slots 610 are spaced apart along the circumference of the light passage 311. In one specific embodiment, three latching slots 610 are provided, and the three latching slots 610 are equally spaced along the circumference of the light passage 311.

[0060] In another embodiment of this application, the lens 40 is not limited to being fixed by a structure with a fixing ring 60. Alternatively, the peripheral edge of the light-emitting side of the lens 40 can be fixed to the end face of the first end of the rotating part 310 away from the cylinder 10, thereby fixing the lens 40.

[0061] The lens 40 and the rotating part 310 can be fixed by fasteners such as screws or by adhesive.

[0062] like Figure 3 , Figures 5 to 7 As shown, the adjustment assembly 30 also includes a fixed frame 320 and a damping structure 330. The fixed frame 320 is an annular structure and is disposed on the inner wall surface of the cylinder 10. The rotating part 310 is rotatably disposed on the fixed frame 320. The inner wall surface of the fixed frame 320 is a second spherical surface that slides and engages with the outer surface of the rotating part 310. The rotating part 310 and the fixed frame 320 are configured with a first spherical surface and a second spherical surface engaging, which ensures the stable rotation of the rotating part 310.

[0063] The damping structure 330 is mounted on the fixed frame 320 and abuts against the outer surface of the rotating part 310 to provide damping. The damping structure 330 provides necessary support and damping for the rotation of the rotating part 310, ensuring the stability and feel of the beam angle adjustment, while also improving the flexibility and stability of the beam angle adjustment, providing good tactile feedback, and enhancing the user experience.

[0064] Specifically, the fixing frame 320 in this application can be an integral annular structural component, or it can be formed by splicing two annular structural components arranged along the axial direction of the cylinder 10. When the fixing frame 320 includes two structural components, the fixing frame 320 includes a first frame 321 and a second frame 322 that are detachably connected along the axial direction of the cylinder 10. Both the first frame 321 and the second frame 322 are provided with a plurality of damping structures 330 that are spaced apart along the circumference of the fixing frame 320. The damping structures 330 on the first frame 321 and the second frame 322 are formed to form a plurality of abutment areas with the turning part along the axial direction of the cylinder 10. Furthermore, the plurality of damping structures 330 are formed to form a plurality of damping points along the axial and circumferential directions of the cylinder 10, which helps to ensure that the rotating part 310 can stay at any position when it rotates to that position, thereby improving the stability of the downlight.

[0065] In this embodiment, the damping structures 330 on the first frame 321 and the second frame 322 are alternately arranged along the circumference of the fixed frame 320. The multiple damping structures 330 adopt an alternating arrangement, which can reduce the use of damping structures 330, simplify the structure, and at the same time have a good damping effect.

[0066] The damping structure 330 and the rotating part 310 are formed in an interference fit. By abutting the outer surface of the rotating part 310, the damping structure 330 provides abutment to the rotating part 310. The abutment force forms a damping on the rotating part 310, which helps to ensure that the rotating part 310 can be rotated to any position and then be held in the corresponding position by damping.

[0067] In this embodiment, two different implementations are provided depending on the damping structure 330.

[0068] like Figure 6 and Figure 7 In the specific embodiment shown, the damping structure 330 is a positioning bead, and the inner wall surface of the fixing frame 320 has a mounting groove with an opening facing the rotating part 310. At least a portion of the positioning bead is disposed inside the mounting groove, and the ball of the positioning bead abuts against and rolls against the outer surface of the rotating part 310.

[0069] The positioning bead is a known positioning bead in the prior art. The ball of the positioning bead abuts against the outer surface of the rotating part 310, and the ball rolls with the rotating part 310 during the rotation of the rotating part 310. The structure of the positioning bead helps to improve the smoothness of the rotation of the rotating part 310, facilitates the rotation operation of the rotating part 310, improves the efficiency of the position switching of the rotating part 310, and improves the user experience of operating the rotating part 310.

[0070] In this embodiment, the material and size of the positioning bead can be set according to the actual usage environment and user needs.

[0071] In a specific embodiment not shown, the damping structure 330 includes an elastic arm and a spherical protrusion. The first end of the elastic arm is disposed on the fixing frame 320, and the spherical protrusion is disposed on the second end of the elastic arm. The spherical surface of the spherical protrusion abuts against and slides against the outer surface of the rotating part 310. When the spherical protrusion abuts against the outer surface of the rotating part 310, the elastic arm undergoes slight deformation. At this time, under the action of the elastic force of the elastic arm, the spherical protrusion has an abutting force against the rotating part 310. The abutting force forms a damping force, so that the rotating part 310 stays at a preset position.

[0072] The elastic coefficient of the elastic arm and the size of the spherical protrusion can be set according to the actual use environment and user needs.

[0073] Specifically, multiple circumferential damping structures 330 are provided along the fixed frame 320, and the multiple damping structures 330 form multiple contact areas with the rotating part 310, which helps to improve the stability of the rotating part 310.

[0074] In this embodiment, the extension directions of two adjacent elastic arms are opposite. Along the circumference of the fixing frame 320, the fixing frame 320 has multiple notches. The second end of one of the adjacent elastic arms is positioned opposite to the notch and can deform towards the interior of the notch to ensure contact with the rotating part 310. Along the axial direction of the cylinder 10, the second end of the other elastic arm of the two adjacent elastic arms extends to the outside of the fixing frame 320 and can deform towards the side opposite to the rotating part 310. One of the two adjacent elastic arms deforms towards the interior of the notch, while the other deforms on the outside of the fixing frame 320, thereby enabling both elastic arms with opposite extension directions to contact the rotating part 310. Furthermore, the two elastic arms with different extension directions provide axially different contact areas with the rotating part 310, and these contact areas are alternately arranged along the circumference of the fixing frame 320.
