Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to an illumination angle adjustment component and an angle-adjustable lamp. Background Technology

[0002] Lighting fixtures are a general term for lighting tools, referring to devices that can transmit, distribute, and change the light distribution of a light source. This includes all components, except the light source itself, necessary for fixing and protecting it. If the lighting fixture has an adjustable illumination angle, the light emission direction can be changed. For example, in the invention patent application CN201110052821.6, the lamp head and lamp holder are connected by a rotating shaft, allowing the lamp head to rotate relative to the lamp holder. Another example is the utility model patent application CN201420145780.4, where the LED light engine is rotatably connected to the downlight ring via an angle adjustment structure, allowing the lamp head to rotate relative to the ring. Yet another example is the utility model patent application CN201920589831.5, where the light-emitting component is mounted on a rotating frame, which is rotatably connected to a fixed component, allowing the lamp head to rotate relative to the fixed component. And yet another example is the application CN202021270779. The utility model patent application with application number CN202010486414.5 shows that the lamp head is rotatably connected to the face ring structure via a rotating ring, thereby achieving a rotatable connection between the lamp head and the face ring; another example is the invention patent application with application number CN202321484018.4, where the lamp head is rotatably connected to the mounting bracket, achieving a rotatable connection between the lamp head and the mounting bracket; yet another example is the utility model patent application with application number CN202321484018.4, where the light source assembly is rotatably connected to the outer ring via an inner ring and a middle ring, achieving a rotatable connection between the lamp head and the face ring.

[0003] The aforementioned lamps all feature a lamp head that can rotate or swing relative to the face ring or other structures used to fix the lamp head to the ceiling, allowing for changes in the light emission direction. The lamp head typically includes a heat sink, LED chips, a lamp panel, and optical components, resulting in a relatively large overall volume. If installation space is limited, insufficient space can be reserved for the rotation or swing of the lamp head, causing interference and reducing the adjustable range of the illumination angle, thus hindering its versatility. Conversely, adjusting the shape of the heat sink to reduce the overall volume of the lamp head, such as with an elephant trunk lamp, would significantly impact heat dissipation, thereby affecting the lamp's lifespan.

Detailed Implementation

[0041] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0042] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] This application provides an illumination angle adjustment component. The illumination angle adjustment component includes a support member, a light source member, and an optical component. The light source member emits light, at least partially entering the optical component, and the optical component redirects the light for emission. Both the light source member and the optical component are disposed on the support member, and at least one of the light source member and the optical component is capable of rotating and / or oscillating relative to the support member to change the emission angle of the light emitted by the optical component.

[0045] The aforementioned illumination angle adjustment component allows light emitted from the light source to at least partially enter the optical component, which then redirects the light back out. In conjunction with the fact that at least one of the light source and the optical component can rotate and / or oscillate relative to the support member, the projection angle of the light emitted from the optical component is changed. This ensures that the illumination angle adjustment is achieved simply by rotating and / or oscillating the optical and light source components relative to the support member. Without adjusting the size of the heat sink, and while ensuring heat dissipation, this effectively reduces the space required for rotation and / or oscillation when implementing the illumination angle adjustment function. This allows it to be applied to angle-adjustable lamps, significantly improving the versatility of angle-adjustable lamps.

[0046] It should be noted that, especially when the light source and optical components rotate synchronously, the simultaneous rotation and / or oscillation of the optical components can be achieved with a relatively small reserved space, while still ensuring a large adjustable range of illumination angle.

[0047] To better understand the illumination angle adjustment component of this application, the following further explanation is provided: Please see Figure 27 , Figure 28 , Figure 29 , Figure 30 , Figure 31 , Figure 32 or Figure 33 One embodiment of the illumination angle adjustment component 10 includes a support member 800, a light source member 400, and an optical element 300. The light source member 400 emits light, at least partially entering the optical element 300, and the light is redirected and emitted again through the optical element 300. Both the light source member 400 and the optical element 300 are disposed on the support member 800. At least one of the light source member 400 and the optical element 300 is capable of rotating and / or oscillating relative to the support member 800 to change the emission angle of the light emitted by the optical element 300.

[0048] The aforementioned illumination angle adjustment component 10 allows the light emitted by the light source 400 to at least partially enter the optical component 300, so that the light is redirected and emitted again through the optical component 300. In conjunction with the fact that at least one of the light source 400 and the optical component 300 can rotate and / or oscillate relative to the support member 800, the emission angle of the light emitted by the optical component 300 can be changed. This allows the illumination angle adjustment process to be achieved simply by rotating and / or oscillating the optical component 300 and the light source 400 relative to the support member 800. Without adjusting the volume of the heat sink, and while ensuring heat dissipation, this effectively reduces the space required for rotation and / or oscillation when implementing the illumination angle adjustment function, making it suitable for angle-adjustable lamps and significantly improving the versatility of angle-adjustable lamps.

[0049] In some embodiments, the light source is at least a structure capable of converting electrical energy into light energy, such as LED beads combined with a lamp panel, for emitting light. Furthermore, the light source also includes a heat sink, with the lamp panel in contact with the heat sink.

[0050] It is understood that at least one of the light source and the optical component can rotate and / or oscillate relative to the support member, i.e., there are three possible arrangements, specifically: In some embodiments, the light source is rotatably and / or oscillatingly connected to the support, and the optical element is mounted on the support; or, In other embodiments, the light source is mounted on the support, and the optical element is rotatably and / or oscillatingly connected to the support; or, In some other embodiments, the light source and the optical element are independently rotatable and / or oscillating connected to the support.

[0051] The following provides further explanation of each plan: The above-mentioned solution involves the light source being connected to the support member by relative rotation and / or oscillation.

[0052] It should be noted that by rotating or oscillating the light source relative to the support, the light source ultimately appears to oscillate relative to the support, thereby changing the angle at which the light emitted by the light source enters the optical component. Furthermore, the light source ultimately appears to oscillate 360° relative to the support.

[0053] Please refer to the following: Figures 1 to 14 In some embodiments, the illumination angle adjustment component 10 further includes a connector 500 and an adjustment component 600. The light source component 400 is connected to the connector 500 on the side near the optical component 300. The adjustment component 600 is disposed on the connector 500 and the support component 800, and at least one of the connector 500 and the support component 800 is rotatably and / or oscillatingly connected to the adjustment component 600 to change the incident light projection angle of the light entering the optical component 300.

[0054] In some embodiments, the connector is a plastic connector. Further, the adjusting member is a plastic adjusting member.

[0055] Please refer to the following: Figures 1 to 4 In some embodiments, the adjustment member 600 is mounted on the connector 500, and the adjustment member 600 is rotatably and / or oscillatingly connected to the support member 800.

[0056] Example 1, please refer to Figure 1 The adjusting member 600 is a bolt. One end of the adjusting member 600 is connected to the connecting member 500, and the other end of the adjusting member 600 is rotatably connected to the supporting member 800. The adjusting member 600 is located on the outer periphery of the light source member 400.

[0057] Example 2, please refer to Figure 2 The adjusting member 600 is a rotating shaft, one end of the adjusting member 600 is connected to the connecting member 500, the other end of the adjusting member 600 is rotatably connected to the supporting member 800, and the adjusting member 600 is located on the outer periphery of the light source member 400.

[0058] Example 3, please refer to Figure 3 The adjustment member 600 has a first arc-shaped groove 602 on its sidewall. The first arc-shaped groove 602 extends away from the optical element 300 and extends circumferentially along the light source element 400. A portion of the support member 800 is slidably connected to the first arc-shaped groove 602 and rotatably connected to the adjustment member 600. Please refer to [link / reference needed]. Figure 4The first arc-shaped groove 602 can also be formed on the support member 800, and part of the adjusting member 600 is slidably connected to the first arc-shaped groove 602 and rotatably connected to the support member 800.

[0059] Please refer to the following: Figures 5 to 13 In some embodiments, the adjustment member 600 is rotatably and / or oscillatingly connected to the connector 500, and the adjustment member 600 is mounted on the support member 800.

[0060] Example 4, please refer to Figure 5 The adjusting member 600 is a bolt. One end of the adjusting member 600 is connected to the support member 800, and the other end of the adjusting member 600 is rotatably connected to the connecting member 500. The adjusting member 600 is located on the outer periphery of the light source member 400.

[0061] Example 5, please refer to Figure 6 The adjusting member 600 is a rotating shaft. One end of the adjusting member 600 is connected to the support member 800, and the other end of the adjusting member 600 is rotatably connected to the connecting member 500. The adjusting member 600 is located on the outer periphery of the light source member 400.

[0062] Example 6, please refer to Figure 7 The connector 500 has a second arc-shaped groove 502 on its sidewall. The second arc-shaped groove 502 extends away from the optical element 300 and extends circumferentially along the light source element 400. A portion of the adjustment element 600 is slidably connected to the second arc-shaped groove 502 and rotatably connected to the connector 500. Alternatively, the second arc-shaped groove 502 can be formed on the adjustment element 600, with a portion of the connector 500 slidably connected to the second arc-shaped groove 502 and rotatably connected to the adjustment element 600.

[0063] Example 7, please refer to Figure 8 The connector 500 is provided with a first spherical surface 503, which is disposed in a way that avoids the light source component 400. Further, the adjusting component 600 is provided with a second spherical surface 603, which is disposed in a way that avoids the optical component 300. The second spherical surface 603 is attached to the first spherical surface 503, so that the adjusting component 600 can rotate relative to the connector 500.

[0064] Further, a first spherical surface 503 is disposed on the outer peripheral wall of the connector 500; a second spherical surface 603 is disposed on the inner peripheral wall of the adjusting member 600, with the first spherical surface 503 abutting against the second spherical surface 603, so that the first spherical surface 503 can rotate and / or swing relative to the second spherical surface 603. Further, the connector 500 is snapped onto the adjusting member 600. Further, the maximum width of the cross-section formed by the first spherical surface 503 of the connector 500 is greater than the minimum width of the cross-section formed by the second spherical surface 603 of the adjusting member 600.

[0065] Alternatively, the first spherical surface is disposed on the inner peripheral wall of the connector, and the second spherical surface is disposed on the outer peripheral wall of the adjusting member, with the first spherical surface abutting against the second spherical surface. Further, the connector is snapped onto the adjusting member. Further still, the maximum width of the cross-section formed by the second spherical surface of the adjusting member is greater than the minimum width of the cross-section formed by the first spherical surface of the connector.

[0066] Furthermore, the adjusting member and the connecting member are magnetically connected. Further, a magnetic element, such as a magnet, is provided on the first spherical surface, and the magnetic element is embedded within the first spherical surface; or, the exposed surface of the magnetic element is parallel to the first spherical surface. Similarly, a magnetic element, such as a magnet, is provided on the second spherical surface, and the magnetic element is embedded within the second spherical surface; or, the exposed surface of the magnetic element is parallel to the second spherical surface. Alternatively, both the adjusting member and the connecting member are magnetic elements, such as magnets.

[0067] It is understood that the first and second spherical surfaces can be annular, the remaining portion of an annular surface after radial cutting, or the remaining portion after a complete spherical surface is transversely cut. Furthermore, the first and second spherical surfaces can be continuous or discontinuous. For example, an annular spherical surface can be cut at least four times to form two independent partial spherical surfaces, which together serve as the first spherical surface, reducing interference between the connectors, adjusters, and supports.

[0068] It is understandable that, in the case of an angle-adjustable luminaire, the optical components are located at the front of the light source. That is, after the angle-adjustable luminaire is installed on the ceiling, the optical components are exposed, while the light source is concealed within the ceiling. This means that to adjust the illumination angle of the angle-adjustable luminaire, the entire luminaire must be removed from the ceiling, the light source rotated and / or swung, and then the luminaire reinstalled. This results in poor angle adjustment convenience and makes it difficult to meet user needs. Therefore, to better meet user needs, it is necessary to improve the ease of use of angle-adjustable luminaires.

[0069] Please refer to Example 8 as well. Figures 9 to 12The connector 500 has a first wedge-shaped cross-section 501, and the light source 400 is connected to the first wedge-shaped cross-section 501, which faces the optical component 300. Further, the connector 500 is rotatably connected to the adjusting component 600, and the rotation axis of the connector 500 is parallel to the height direction of the first wedge-shaped cross-section 501. It can be understood that the height of the wedge-shaped cross-section refers to the vertical distance between its top and bottom, and the height direction is the length direction of the vertical distance between the top and bottom.

[0070] Further, the connector 500 is provided with a first gear 510, which is arranged circumferentially around the connector 500. Further, the illumination angle adjustment component 10 also includes an auxiliary adjustment component 700, which is rotatably connected to the adjustment component 600. The rotation axis of the auxiliary adjustment component 700 is parallel to the rotation axis of the connector 500. The auxiliary adjustment component 700 is provided with a second gear 710, which is arranged circumferentially around the auxiliary adjustment component 700. The first gear 510 and the second gear 710 are meshed together. Further, the auxiliary adjustment component 700 at least partially protrudes from the support component 800. Further, the auxiliary adjustment component is disposed away from the optical component, and also away from structures used to mount the optical component, such as the auxiliary adjustment component being disposed away from both the fixing component and the adjusting component.

[0071] It is understood that the connector 500 is provided with a first wedge-shaped section 501, and the light source 400 is connected to the first wedge-shaped section 501. With the rotation axis of the connector 500 parallel to the height direction of the first wedge-shaped section 501, the light source 400 can be rotated 360 degrees with less or no reserved space. This allows the adjusting member 600 to rotate the projection direction of the light emitted by the light source 400 360 degrees, effectively realizing the 360-degree arbitrary rotation and adjustment of the illumination direction of the angle-adjustable lamp. In addition, the angle-adjustable lamp can also adjust the projection direction of the light after installation, making it highly convenient to use.

[0072] Furthermore, the adjusting member 600 is provided with a clearance hole 601. Further, the auxiliary adjusting member 700 includes an engaging portion 720 and a handle portion 730. The engaging portion 720 is rotatably connected to the adjusting member 600. The second gear 710 is connected around the outer periphery of the engaging portion 720. The rotation axis of the engaging portion 720 is parallel to the rotation axis of the connecting member 500. The handle portion 730 passes through the clearance hole 601 and is connected to the end of the engaging portion 720. The handle portion 730 is rotatably connected to the adjusting member 600. The rotation axis of the handle portion 730 is the same as the rotation axis of the engaging portion 720. The handle portion 730 at least partially protrudes from the support. Furthermore, both the engaging portion 720 and the handle portion 730 are disposed away from the optical element 300, and both the engaging portion 720 and the handle portion 730 are also disposed away from the structures used to mount the optical element 300, such as the engaging portion 720 and the handle portion 730 being disposed away from the fixing member and the adjusting member, respectively. Furthermore, the end of the engaging portion 720 is provided with an insertion groove 701; the end of the handle portion 730 is provided with a protruding insertion block 740, which is inserted into the insertion groove 701, so that the handle portion 730 is inserted into the engaging portion 720. This effectively reduces the impact of the auxiliary adjusting member 700 on the light output effect of the angle-adjustable lamp and effectively improves the ease of use of the angle-adjustable lamp. Furthermore, the engaging portion 720 is engaged at the clearance hole 601, and the engaging portion 720 is rotatably connected to the adjusting member 600.

[0073] This is understandable; please refer to [link / reference]. Figure 13The meshing part 720 is rotatably connected to the adjusting member 600. Furthermore, the meshing part 720 is engaged with and rotatably connected to the adjusting member 600. If the meshing part 720 is engaged too tightly with the adjusting member 600, the smoothness of its rotation will be poor. Conversely, if the meshing part 720 is engaged too loosely with the adjusting member 600, the meshing stability of the first gear 510 and the second gear 710 will be poor, significantly affecting the rotational stability of the adjusting member 600. Therefore, in this application, to better ensure the smoothness of the rotation of the meshing part 720 and thus the user's experience, while also ensuring the rotational stability of the adjusting member 600, in one embodiment, the inner wall of the clearance hole 601 is an outwardly convex arc surface 6011, and the meshing part 720 abuts against the outwardly convex arc surface 6011. It is understood that when the inner wall of the clearance hole 601 is an outwardly convex arc surface 6011, the hole wall of the clearance hole 601 only linearly abuts against the meshing part 720, effectively ensuring that the meshing part 720 is stably engaged in the clearance hole 601, and causing the clearance hole 601 to allow the meshing part 720 to swing within it, so that after the hand part 730 is inserted into the insertion groove 701 of the meshing part 720, it drives the meshing part 720 to swing towards the first gear 510, thereby achieving stable meshing of the first gear 510 and the second gear 710 to adjust the rotational stability of the adjusting member 600.

[0074] Please see Figure 14 In some embodiments, the adjusting member 600 is rotatably and / or oscillatingly connected to the connecting member 500, and the adjusting member 600 is also rotatably and / or oscillatingly connected to the supporting member 800, with the rotation axis of the adjusting member 600 intersecting the rotation axis of the connecting member 500. Preferably, the rotation axis of the adjusting member 600 is perpendicular to the rotation axis of the connecting member 500. Further, the plane containing the rotation axes of the adjusting member 600 and the connecting member 500 intersects the propagation direction of the light emitted by the light source 400.

[0075] Example 9, please refer to Figure 14 The adjusting member 600 has a first rotating rod 610 protruding from its side wall. The first rotating rod 610 is rotatably connected to the supporting member 800. The first rotating rod 610 is offset from the optical member 300 and is located on the outer periphery of the light source member 400. Further, the connecting member 500 has a second rotating rod 520 protruding from its outer wall. The light source member 400 is exposed at least one end wall of the connecting member 500, and the second rotating rod 520 is rotatably connected to the adjusting member 600.

[0076] The above-mentioned solution involves rotating and / or oscillating the optical components connected to the support.

[0077] It should be noted that by rotating or oscillating the optical component relative to the support, the optical component ultimately oscillates relative to the support, thereby changing the light emission angle of the light emitted by the optical component. Furthermore, the optical component ultimately oscillates 360° relative to the support.

[0078] Please see Figures 15 to 26 In some embodiments, the illumination angle adjustment component 10 further includes a fixing member 100 and an adjusting member 200. The optical element 300 passes through the fixing member 100 and is connected to the fixing member 100. The adjusting member 200 is disposed on the fixing member 100 and the support member 800, and at least one of the fixing member 100 and the support member 800 is rotatably and / or oscillatingly connected to the adjusting member 200 to change the light emission angle of the light emitted by the optical element 300.

[0079] In some embodiments, the fastener is a plastic fastener. Further, the adjusting member is a plastic adjusting member.

[0080] Please refer to the following: Figures 15 to 18 In some embodiments, the adjusting member 200 is mounted on the fixing member 100, and the adjusting member 200 is rotatably and / or oscillatingly connected to the support member 800.

[0081] Example 10, please refer to Figure 15 The adjusting member 200 is a bolt. One end of the adjusting member 200 is connected to the fixing member 100, and the other end of the adjusting member 200 is rotatably connected to the support member 800. The adjusting member 200 is located on the outer periphery of the optical member 300.

[0082] Example 11. Please refer to [link / reference]. Figure 16 The adjusting member 200 is a rotating shaft. One end of the adjusting member 200 is connected to the fixing member 100, and the other end of the adjusting member 200 is rotatably connected to the support member 800. The adjusting member 200 is located on the outer periphery of the optical member 300.

[0083] Example 12, please refer to Figure 17 The adjusting member 200 has a third arc-shaped groove 203 on its side wall. The third arc-shaped groove 203 extends away from the light source member 400 and extends circumferentially along the optical member 300. A portion of the supporting member 800 is slidably connected to the third arc-shaped groove 203 and rotatably connected to the adjusting member 200. (For further information, please refer to [link / reference]). Figure 18 The third arc-shaped slide groove 203 can also be formed on the support member 800, and part of the adjusting member 200 is slidably connected to the third arc-shaped slide groove 203 and rotatably connected to the support member 800.

[0084] Please refer to the following: Figures 19 to 25 In some embodiments, the adjusting member 200 is rotatably and / or oscillatingly connected to the fixing member 100, and the adjusting member 200 is mounted on the support member 800.

[0085] Example 13, please refer to Figure 19 The adjusting member 200 is a bolt. One end of the adjusting member 200 is connected to the support member 800, and the other end of the adjusting member 200 is rotatably connected to the fixing member 100. The adjusting member 200 is located on the outer periphery of the optical member 300.

[0086] Example 14, please refer to Figure 20 The adjusting member 200 is a rotating shaft. One end of the adjusting member 200 is connected to the support member 800, and the other end of the adjusting member 200 is rotatably connected to the fixing member 100. The adjusting member 200 is located on the outer periphery of the optical member 300.

[0087] Example 15, please refer to Figure 21 The side wall of the fixing member 100 is provided with an arc-shaped sliding groove 102. The arc-shaped sliding groove 102 extends away from the light source member 400 and extends along the circumference of the optical member 300. The adjusting member 200 is slidably connected to the arc-shaped sliding groove 102 and rotatably connected to the fixing member 100.

[0088] Please refer to Example 16 as well. Figures 22 to 24 The fixing member 100 is provided with a third spherical surface 101, which is disposed in a way that avoids the optical component 300. Further, the adjusting member 200 is provided with a fourth spherical surface 201, which is disposed in a way that avoids the light source component 400. The fourth spherical surface 201 is attached to the third spherical surface 101, so that the adjusting member 200 can rotate relative to the fixing member 100.

[0089] Furthermore, please refer to the following: Figures 22 to 23 The third spherical surface 101 is disposed on the outer peripheral wall of the fixing member 100; the fourth spherical surface 201 is disposed on the inner peripheral wall of the adjusting member 200, and the third spherical surface 101 is attached to the fourth spherical surface 201 so that the third spherical surface 101 can rotate and / or swing relative to the fourth spherical surface 201. Further, the fixing member 100 is snapped onto the adjusting member 200. Further, the maximum width of the cross-section formed by the cross-section of the third spherical surface 101 of the fixing member 100 is greater than the minimum width of the cross-section formed by the cross-section of the fourth spherical surface 201 of the adjusting member 200.

[0090] Alternatively, the third spherical surface is disposed on the inner peripheral wall of the fixing member, and the fourth spherical surface is disposed on the outer peripheral wall of the adjusting member, with the third spherical surface abutting against the fourth spherical surface. Further, the fixing member is snapped onto the adjusting member. Further still, the maximum width of the cross-section formed by the cross-section of the fourth spherical surface of the adjusting member is greater than the minimum width of the cross-section formed by the cross-section of the third spherical surface of the fixing member.

[0091] Further, please refer to Figure 24 The adjusting member 200 and the fixing member 100 are magnetically connected. Further, a magnetic element, such as a magnet, is provided on the third spherical surface 101. The magnetic element is embedded within the third spherical surface 101, or the exposed surface of the magnetic element is parallel to the third spherical surface 101. Similarly, a magnetic element, such as a magnet, is provided on the fourth spherical surface 201. The magnetic element is embedded within the fourth spherical surface 201, or the exposed surface of the magnetic element is parallel to the fourth spherical surface 201.

[0092] Alternatively, both the adjusting element 200 and the fixing element 100 may be magnetic, such as magnets.

[0093] Furthermore, the third and fourth spheres can be annular, the remaining portion of an annular surface after radial cutting, or the remaining portion after a complete sphere is transversely cut. Moreover, the third and fourth spheres can be continuous or discontinuous; for example, an annular sphere can be cut at least four times to form two independent partial spheres, which together serve as the third sphere, reducing interference between the fixing components, adjusting components, and supporting components.

[0094] Furthermore, please refer to the following: Figures 22 to 24 The adjusting member 200 has a beam channel 202 through which light passes. The fourth spherical surface 201 is an annular concave spherical surface located on the inner wall of the adjusting member 200 and communicating with the beam channel 202. Further, the fixing member 100 is an annular fixing member 100, and the third spherical surface 101 is an annular convex spherical surface located on the outer wall of the annular fixing member 100 and closely attached to the annular concave spherical surface. The annular fixing member 100 is rotatably connected to the fixing member 100 with the center of the annular convex spherical surface as the rotation point. The optical element 300 is connected to the inner wall of the annular fixing member 100 and blocks the beam channel 202.

[0095] It is understood that the optical element 300 is connected to the inner wall of the adjusting element 200, and the optical element 300 is sealed at the beam channel 202, while the light emitted by the light source element 400 passes through the beam channel 202. Thus, adjusting the rotation and / or swing angle of the optical element 300 on the adjusting element 200 can complete the adjustment of the light projection angle. Furthermore, the annular fixing element 100 is rotatably connected to the fixing element 100 with the center of the annular convex spherical surface as the rotation point. This allows the adjusting element 200 to rotate 360 ​​degrees, thereby enabling the adjusting element 200 to drive the projection direction of the light emitted by the optical element 300 to rotate 360 ​​degrees, while the light source element 400 does not actually rotate. This effectively avoids the problem of the drive power supply wire getting tangled, and effectively realizes the 360-degree arbitrary rotation adjustment of the illumination direction of the angle-adjustable lamp. In addition, the angle-adjustable lamp can also adjust the projection direction of the light after installation, making it highly convenient to use.

[0096] Example 17, please refer to Figure 25 The fixing member 100 has a second wedge-shaped cross section 103, on which the optical element 300 is exposed. The second wedge-shaped cross section 103 is positioned away from the light source element 400. Further, the fixing member 100 is rotatably connected to the adjusting member 200, and the rotation axis of the fixing member 100 is parallel to the height direction of the second wedge-shaped cross section 103. It can be understood that the height of the wedge-shaped cross section refers to the vertical distance between its top and bottom, and the height direction is the length direction of the vertical distance between the top and bottom. In this way, the adjusting member 200 can rotate 360 ​​degrees, thereby enabling the adjusting member 200 to drive the projection direction of the light emitted by the optical element 300 to rotate 360 ​​degrees, while the light source element 400 does not actually rotate. This effectively avoids the drive power supply wires from getting tangled and effectively achieves 360-degree arbitrary rotation adjustment of the illumination direction of the angle-adjustable lamp. Furthermore, the angle-adjustable lamp allows for adjustment of the light projection direction after installation, providing high ease of use.

[0097] Please refer to the following: Figure 26 In some embodiments, the adjusting member 200 is rotatably and / or oscillatingly connected to the fixing member 100, and the adjusting member 200 is also rotatably and / or oscillatingly connected to the supporting member 800, with the rotation axis of the adjusting member 200 intersecting the rotation axis of the fixing member 100. Preferably, the rotation axis of the adjusting member 200 is perpendicular to the rotation axis of the fixing member 100. Further, the plane containing the rotation axes of the adjusting member 200 and the fixing member 100 intersects the propagation direction of the light emitted by the light source member 400.

[0098] Example 18, please refer to Figure 26The adjusting member 200 has a third rotating rod 210 protruding from its outer wall. The third rotating rod 210 is rotatably connected to the supporting member 800. The third rotating rod 210 is offset from the light source member 400 and is located on the outer periphery of the optical member 300. Further, the fixing member 100 has a fourth rotating rod 110 protruding from its outer wall. The optical member 300 is exposed at both ends of the fixing member 100, and the fourth rotating rod 110 is rotatably connected to the adjusting member 200. In this way, the adjusting component 200 and the fixing component 100 can be rotated 360 degrees, which in turn allows the adjusting component 200 to drive the projection direction of the light emitted by the optical component 300 to rotate 360 ​​degrees, while the light source component 400 does not actually rotate. This effectively avoids the problem of the driving power supply wire getting tangled, and effectively realizes the 360-degree arbitrary rotation adjustment of the illumination direction of the angle-adjustable lamp. In addition, the angle-adjustable lamp can also adjust the projection direction of the light after installation, making it highly convenient to use.

[0099] Please refer to the following: Figures 22 to 23 In some embodiments, the optical element 300 includes a lens 310. Further, the outer peripheral wall of the lens 310 is connected to the fixing member 100. Further, the lens 310 is a TIR lens 310. Further, the number or type of the lenses 310 can be several, and the stacking order of the lenses 310 is determined according to conventional methods or desired effects, and the lenses 310 are installed using conventional methods for connecting the lenses 310 to the rotation adjustment member 200.

[0100] In some embodiments, the optical element 300 further includes a honeycomb mesh 320 and / or a fitting ring 330, wherein the lens 310, the honeycomb mesh 320, and the fitting ring 330 are stacked sequentially, with the honeycomb mesh 320 and the fitting ring 330 located on the side of the lens 310 away from the light source element 400. Further, the lens 310, the honeycomb mesh 320, and the fitting ring 330 are connected together to the fixing member 100. Further, if not present, they are left unused.

[0101] It can be understood that the support component is a structure installed on the ceiling, such as a face ring, or it can include a structure that is installed on the ceiling but does not move relative to the ceiling, such as a lamp housing.

[0102] This application also provides an angle-adjustable lamp. One embodiment of the angle-adjustable lamp includes a driving power supply and an illumination angle adjustment component as described in any of the above embodiments, wherein the driving power supply is electrically connected to the light source element. Further, please refer to... Figure 27 , Figure 28 , Figure 29 , Figure 30 , Figure 31 , Figure 32 or Figure 33 In this embodiment, the illumination angle adjustment component 10 includes a support member 800, a light source member 400, and an optical element 300. The light source member 400 emits light, and at least a portion of the light enters the optical element 300, which then guides the light back out. Both the light source member 400 and the optical element 300 are disposed on the support member 800. At least one of the light source member 400 and the optical element 300 can rotate and / or oscillate relative to the support member 800 to change the light projection angle emitted by the optical element 300.

[0103] Compared with the prior art, the present invention has at least the following advantages: The illumination angle adjustment component 10 of the present invention allows light emitted by the light source 400 to at least partially enter the optical component 300, so that the light is redirected and emitted again through the optical component 300. In conjunction with the fact that at least one of the light source 400 and the optical component 300 can rotate and / or oscillate relative to the support member 800, the emission angle of the light emitted by the optical component 300 can be changed. This allows the illumination angle adjustment process to be achieved simply by rotating and / or oscillating the optical component 300 and the light source 400 relative to the support member 800. Without adjusting the volume of the heat sink, and while ensuring heat dissipation, this effectively reduces the space required for rotation and / or oscillation when implementing the illumination angle adjustment function, making it applicable to angle-adjustable lamps and significantly improving the versatility of angle-adjustable lamps.

[0104] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
