Abstract
Description
Technical Field
[0001] This invention belongs to the field of downlight technology, specifically relating to a concealed downlight based on a film-coated panel material. Background Technology
[0002] As a mainstream solution for architectural decorative lighting, recessed downlights directly affect the aesthetic performance and energy efficiency of a space due to their controllable luminous efficacy and environmental adaptability. However, existing downlights have significant technical shortcomings in dynamic light field adjustment, the application of environmentally friendly materials, and long-term dustproof maintenance, resulting in rigid luminous efficacy, high maintenance costs, and increased environmental impact.
[0003] Specifically, firstly, traditional downlights are mostly installed at a fixed angle (usually a beam angle of 15 to 30 degrees), and the shape of the light spot ("hill") is limited by the structure of the lamp and cannot be dynamically adjusted according to the needs of the scene. In actual use, due to the diversity of home decoration, everyone's needs and aesthetics are different, and existing conventional downlights cannot select whether or not to change the specific shape of the "hill" according to the user's needs. Furthermore, existing adjustable downlights have limited adjustable illumination range, and each angle adjustment is time-consuming and has low adjustment accuracy. Moreover, the exposed structure of existing downlights disrupts the integrity of the ceiling.
[0004] Secondly, most existing downlight housings are made of aluminum alloy anodizing or plastic electroplating. These materials are not environmentally friendly and are prone to dust accumulation. With long-term use, excessive dust accumulation can affect the light and reduce the aesthetics of the downlight. Summary of the Invention

[0015] In a preferred embodiment, a heat sink is fixedly installed on the upper end of the main body, and eight sets of heat pipes are fixedly connected to the inner cavity of the mounting block. The upper ends of the eight sets of heat pipes all extend into the inner cavity of the heat sink, and only two sets of heat-conducting plates are fixedly connected to the upper ends of the eight sets of heat pipes.
[0016] In a preferred embodiment, the heat-conducting plates are provided in two sets, namely annular and disc-shaped, distributed on the outer edge and upper end of the inner cavity of the heat sink, and the two sets of heat-conducting plates are connected together by heat pipes.
[0017] In a preferred embodiment, the upper end of the lamp core is electrically connected to a cable, and the upper end of the cable is fixedly connected to the inner cavity of the heat sink.
[0018] In a preferred embodiment, the rotating assembly includes a motor, which is fixedly mounted on the upper end of the mounting block. The output shaft of the motor extends into the inner cavity of the mounting block and is fixedly connected to a gear. A slip ring is fixedly connected to the middle of the outer edge of the mounting ring. The outer edge of the slip ring has a toothed groove, and the outer ring of the gear meshes in the toothed groove.
[0019] In a preferred embodiment, the inner cavity of the mounting block is provided with an annular groove and a circular groove, and the two sets of grooves are interconnected. The slip ring and the gear are respectively disposed in the two sets of grooves, and the part of the slip ring that contacts the annular groove is provided with a bearing.
[0020] In a preferred embodiment, the control component further includes a second motor, which is fixedly mounted on the upper end of the mounting block. A gear rod is fixedly connected to the output shaft of the second motor, and the other end of the gear rod is set on the upper end of the mounting block through a bearing and a bracket. A limit tube is fixedly connected to the lower end of the portion of the heat sink that extends into the inner cavity of the main body, and the lifting rod is slidably connected to the inner cavity of the limit tube.
[0021] In a preferred embodiment, both sides of the upper end of the lifting rod are fixedly connected with protruding plates, and both sets of protruding plates are slidably connected to the inner cavity of the limiting tube. The lower ends of both sets of protruding plates are fixedly connected with springs, and the lower ends of both sets of springs are fixedly connected to the lower end of the inner cavity of the limiting tube.
[0022] In a preferred embodiment, the drive assembly further includes a second gear, which is fixedly connected to the outer ring of the upper end of the lead screw. A third gear is rotatably connected to the rear side of the upper end of the limiting tube. The outer ring of the third gear meshes with the inner cavity of the second gear. The shaft of the third gear passes through the limiting tube, and a fourth gear is fixedly connected to the portion of the third gear extending out of the limiting tube.
[0023] In a preferred embodiment, the roller's shaft passes through the lifting rod, and a gear five is fixedly connected to the rear end of the roller's shaft. A gear six is hinged to the upper end of the mounting block via a bracket. The outer ring of the gear six meshes with the outer ring of the gear five. The rear end of the gear six passes through the bracket it is hinged to, and a gear seven is fixedly connected to the rear end of the gear six. Two sets of toothed rings are fixedly connected to the outer ring of the gear rod, and two sets of chains are respectively meshed on the outer rings of the two sets of toothed rings. The other ends of the two sets of chains are respectively meshed on the outer rings of the gear four and the gear seven.
[0024] The technical effects achieved by this invention are as follows:
[0025] The control and drive components of this invention can control the illumination angle of the lamp core according to actual illumination needs, and can disengage from the lamp core after the orientation is adjusted to avoid affecting subsequent orientation adjustments. When adjusting the illumination angle of the lamp core, the drive part of the drive component rotates, causing the lead screw to rotate, which lowers the lifting rod and roller to contact the lamp core. When the roller contacts the lamp core, the lower end of the lead screw disengages from the lifting rod and is only connected to the rotating sleeve, so that no matter how the lead screw rotates, it cannot drive the rotating sleeve and lifting rod to descend, thus avoiding damage to the lamp core caused by squeezing it. When the roller contacts the lamp core, the drive part of the roller engages with the linkage part of the drive component, thereby driving the roller to rotate, which in turn drives the lamp core to rotate and adjust the tilt angle, thereby controlling the illumination direction of the lamp core. After the orientation adjustment is completed, the drive part of the drive component rotates in the opposite direction, causing the lifting rod to rise, which in turn causes the roller to disengage from the lamp core, preventing the roller from contacting the lamp core and affecting subsequent orientation adjustments.
[0026] The rotating component of this invention can adjust the illumination direction of the lamp core after adjusting the illumination angle of the lamp core, thereby achieving a wide range of lamp core adjustment. The illumination position of the lamp core can be adjusted according to the actual application scenario, improving practicality. After the lamp core angle is adjusted, the driving part of the rotating component operates, driving the mounting ring to rotate, which in turn drives the lamp core with the adjusted orientation to rotate together, thereby adjusting the orientation of the lamp core and thus adjusting the orientation angle of the lamp core, which can meet more illumination needs.
[0027] The control component of this invention allows the auxiliary lead screw and lifting rod to reconnect when the lamp wick completes the illumination angle adjustment and resets. This prevents the lead screw from completely detaching from the lifting rod, making it impossible to reconnect the lifting rod by reverse rotation, which would affect normal use. During lamp wick angle adjustment, the lifting rod descends and compresses the retractable part of the control component. When the adjustment is complete and reset is required, the retractable part springs back, causing the lifting rod to rise continuously. This ensures that the lifting rod remains in contact with the lower end of the lead screw and is always under upward pressure, facilitating the reconnection of the auxiliary lead screw and lifting rod and enabling the lifting rod to reset.

[0044] Please see the appendix Figures 1 to 3 and Figures 6 to 7 As shown, this embodiment provides a concealed downlight based on a coated panel material, including:
[0045] The main body 10 has an inner cavity connected to an additional block 12. An installation ring 15 is sleeved in the inner cavity of the additional block 12. A lamp wick 16 is fixedly installed in the inner cavity of the installation ring 15.
[0046] Rotating component 20 is installed in the inner cavity of the mounting block 12;
[0047] The control component 30 includes a lifting rod 34, a roller 35 is hinged to the lower end of the lifting rod 34, the lower end of the roller 35 is in contact with the upper end of the lamp core 16, and a rotating sleeve 37 is rotatably connected to the upper end of the lifting rod 34 through a ball bearing.
[0048] The drive assembly 40 includes a lead screw 41, the lower end of which is movably sleeved in the rotating sleeve 37 and threadedly connected to the lifting rod 34.
[0049] When the lead screw 41 drives the lifting rod 34 to descend, the driving roller 35 descends to contact the lamp core 16, and the roller 35 is used to drive the lamp core 16 to rotate.
[0050] After the roller 35 descends into position, the lead screw 41 switches to being connected only to the rotating sleeve 37 and continues to rotate;
[0051] The rotating component 20 is used to control the orientation of the lamp wick 16.
[0052] It should be noted that the entire mounting block 12 is made of thermally conductive material, and the mounting ring 15 is also made of thermally conductive material. In this embodiment, both sets of thermally conductive materials are preferably made of copper, which aims to improve thermal conductivity and allow the heat generated by the lamp wick 16 to be quickly dissipated.
[0053] The main body 10 is preferably a shell integrally cast from a coated board material, and the main body 10 is divided into five layers, from the inside to the outside: a reflective film layer, an adhesive layer, a substrate, an adhesive layer, and a back film layer. The reflective film layer is preferably a PET reflective film, and the back film layer is one of PP film, PET film, PE film, PVC film, PTFE film, or ETFE film. In this embodiment, PTFE film is preferred, and the substrate is preferably a highly malleable metal sheet. The purpose is to enable the main body 10 to be integrally cast and molded, and in use, the reflective film layer can reflect the light generated by the lamp core 16, thereby improving the brightness and illumination effect of the downlight.
[0054] The inner cavity of the rotating sleeve 37 does not have a threaded groove, so that the lead screw 41 can only rotate within the inner cavity of the rotating sleeve 37 or drive the rotating sleeve 37 to rotate together, and cannot drive the rotating sleeve 37 to descend, thus avoiding applying a large downward force to the roller 35 and preventing damage to the lamp wick 16.
[0055] In this embodiment, during use, the drive assembly 40 drives the lead screw 41 to rotate, causing the lifting rod 34 to descend until the roller 35 is in contact with the lamp core 16. At this time, the lead screw 41 disengages from the lifting rod 34 and rotates within the rotating sleeve 37. Subsequently, the roller 35 connects to the drive assembly 40 and is driven by the drive assembly 40 to rotate, causing the lamp core 16 to rotate and adjust the illumination angle. After the angle adjustment is completed, the drive assembly 40 reverses its direction, causing the roller 35 to disengage from the lamp core 16. Then, the rotating assembly 20 operates, driving the mounting ring 15 and the lamp core 16 to rotate, adjusting the orientation of the lamp core 16, thereby achieving the control of the orientation and angle of the lamp core 16 to meet different illumination needs. Furthermore, during use, the heat of the lamp core 16 is transferred outward through the mounting ring 15 and the mounting block 12 to prevent the temperature from becoming too high and causing damage to the lamp core 16.
[0056] Secondly, please refer to it again. Figure 3 The upper end of the main body 10 is fixedly installed with a heat sink 11, and the inner cavity of the mounting block 12 is fixedly connected with eight sets of heat pipes 13. The upper ends of the eight sets of heat pipes 13 all extend into the inner cavity of the heat sink 11, and only two sets of heat-conducting plates 14 are fixedly connected to the upper ends of the eight sets of heat pipes 13.
[0057] Two sets of heat-conducting plates 14 are provided, namely annular and disc-shaped, distributed on the outer edge and upper end of the inner cavity of the heat sink 11. The two sets of heat-conducting plates 14 are connected together by heat pipes 13, which is intended to quickly disperse heat to various positions of the heat sink 11.
[0058] The upper end of the lamp wick 16 is electrically connected to a cable 17, and the upper end of the cable 17 is fixedly connected to the inner cavity of the heat sink 11.
[0059] It should be noted that multiple sets of heat dissipation fins are provided on the outer edge of the heat sink 11, and the outer edges of the two sets of heat conduction plates 14 are located on the inner side of the heat dissipation fins, so that heat can be quickly dissipated through the heat dissipation fins.
[0060] The mounting ring 15 is in close contact with the outer surface of the lamp core 16, which not only improves the thermal conductivity, but also improves the stability of the lamp core 16 after adjustment by relying on the friction between the mounting ring 15 and the lamp core 16. This ensures that the lamp core 16 can only be driven to rotate when the roller 35 is in close contact with the lamp core 16, thus preventing the lamp core 16 from automatically resetting after the orientation is adjusted, which would affect the adjustment.
[0061] Cable 17 is a flexible spiral cable to prevent the control of the lamp core 16 from being affected when the lamp core 16 is rotated and its angle is adjusted, thus affecting actual use. In use, cable 17 should pass through heat sink 11 and be connected to the mains power so that the lamp core 16 can be powered by the mains power.
[0062] Preferably, in order to ensure that the heat of the lamp wick 16 can be dissipated quickly and that the lamp wick 16 can be used normally, the portion of the eight heat pipes 13 that extends into the inner cavity of the mounting block 12 should be arranged in a ring and spiraled in the inner cavity of the mounting block 12 (not shown in the figure). This will ensure that the heat dissipated by the lamp wick 16 can be quickly transferred to the heat pipes 13 through the mounting ring 15 and dissipated outward.
[0063] In this embodiment, during use, the temperature generated by the lamp wick 16 is transferred to the mounting ring 15, and then through the mounting ring 15, the heat is transferred to the heat pipe 13. The heat pipe 13, utilizing its efficient thermal conductivity, rapidly conducts the heat to the heat-conducting plate 14 inside the heat sink 11. The heat-conducting plate 14 effectively distributes the heat to various areas of the heat sink 11, and the heat is further dissipated through the heat dissipation fins on the outer edge of the heat sink 11, ensuring that the downlight maintains a suitable operating temperature inside.
[0064] Secondly, please refer to it again. Figures 3 to 5 The rotating assembly 20 includes a motor 21, which is fixedly mounted on the upper end of the mounting block 12. The output shaft of the motor 21 extends into the inner cavity of the mounting block 12 and is fixedly connected to a gear 22. A slip ring 23 is fixedly connected to the middle of the outer edge of the mounting ring 15. The outer edge of the slip ring 23 is provided with a toothed groove 24, and the outer ring of the gear 22 meshes in the toothed groove 24.
[0065] The inner cavity of the mounting block 12 is provided with an annular groove and a circular groove, and the two sets of grooves are interconnected. The slip ring 23 and gear 22 are set in the two sets of grooves, and the part of the slip ring 23 that contacts the annular groove is provided with a bearing, which aims to improve the smoothness of the rotation of the slip ring 23 and avoid excessive friction when the slip ring 23 rotates, thus affecting its service life.
[0066] It should be noted that when driving the mounting ring 15 to rotate, the rotation range should be within the initial state, between 0 and 90°, to avoid excessive rotation of the mounting ring 15 and the lamp core 16, which could cause the cable 17 to become tangled and affect subsequent use.
[0067] In this embodiment, when the orientation of the lamp wick 16 needs to be adjusted, the motor 21 starts, driving the gear 22 to rotate. The outer ring of the gear 22 meshes in the tooth groove 24, thereby driving the slip ring 23 to rotate. The slip ring 23 is fixedly connected to the mounting ring 15, so the mounting ring 15 rotates accordingly, and the lamp wick 16 inside the mounting ring 15 also rotates, realizing the adjustment of the orientation of the lamp wick 16. By controlling the rotation angle of the motor 21, the orientation of the lamp wick 16 can be precisely controlled to meet different lighting needs.
[0068] Secondly, please refer to it again. Figures 5 to 8The control component 30 also includes a second motor 31, which is fixedly installed on the upper end of the mounting block 12. A gear rod 32 is fixedly connected to the output shaft of the second motor 31. The other end of the gear rod 32 is set on the upper end of the mounting block 12 through a ball bearing and a bracket. The lower end of the heat sink 11 that extends into the inner cavity of the main body 10 is fixedly connected to a limit tube 33. The lifting rod 34 is slidably connected to the inner cavity of the limit tube 33.
[0069] Both sides of the upper end of the lifting rod 34 are fixedly connected with protruding plates, and both sets of protruding plates are slidably connected to the inner cavity of the limiting tube 33. The lower ends of both sets of protruding plates are fixedly connected with springs 36, and the lower ends of both sets of springs 36 are fixedly connected to the lower end of the inner cavity of the limiting tube 33.
[0070] It should be noted that the inner cavity of the limiting tube 33 is provided with grooves on both sides to adapt to the protrusions on both sides of the lifting rod 34, and the lower end of the spring 36 is installed at the lower end of the groove.
[0071] The outer ring of the roller 35 is made of rubber anti-slip material and is rounded (to improve the fit with the lamp core 16). This is so that when the roller 35 rolls against the outer surface of the lamp core 16, it can drive the lamp core 16 to roll together, thereby adjusting the tilt angle of the lamp core 16. During the reset process, due to the fit between the roller 35 and the outer surface of the lamp core 16, and the friction between the lamp core 16 and the mounting ring 15, the roller 35 only needs to be slightly raised during the reset process to prevent it from driving the lamp core 16 to rotate. This reduces the impact on the orientation of the adjusted lamp core 16 during the reset process.
[0072] In this embodiment, when the lead screw 41 is driven to rotate in the forward direction, it will drive the lifting rod 34 to move downward and drive the roller 35 to descend, compressing the spring 36 until the lower end of the roller 35 contacts the lamp wick 16. At this time, the lower end of the lead screw 41 will disengage from the threaded groove of the lifting rod 34 and will only be movably sleeved in the rotating sleeve 37. Even if the lead screw 41 continues to rotate, it cannot drive the lifting rod 34 to descend further, nor can it apply downward pressure to the lifting rod 34, thus avoiding excessive pressure from the roller 35 on the lamp wick 16, which could damage the outer shell of the lamp wick 16. When it is necessary to reset, the spring 36 will rebound, pushing the lifting rod 34 to move upward. At this time, the lead screw 41 is driven to rotate in the reverse direction and connects with the rising lifting rod 34, so that the lifting rod 34 and the roller 35 are reset and disengaged from the lamp wick 16, thus avoiding affecting the adjustment of the lamp wick 16's orientation.
[0073] Please refer to it again. Figures 6 to 10The drive assembly 40 also includes a second gear 42, which is fixedly connected to the outer ring of the upper end of the lead screw 41. The upper rear end of the limiting tube 33 is rotatably connected to a third gear 43 via a ball bearing. The outer ring of the third gear 43 meshes with the inner cavity of the second gear 42. The shaft of the third gear 43 passes through the limiting tube 33, and the part of the third gear 43 extending out of the limiting tube 33 is fixedly connected to a fourth gear 44.
[0074] The roller 35's shaft passes through the lifting rod 34, and the rear end of the roller 35's shaft is fixedly connected to a gear 45. The upper end of the mounting block 12 is hinged to a gear 46 via a bracket. The outer ring of gear 46 meshes with the outer ring of gear 45. The rear end of gear 46 passes through the bracket it is hinged to, and the rear end of gear 46 is fixedly connected to a gear 47. The outer ring of the gear rod 32 is fixedly connected to two sets of toothed rings, and the outer rings of the two sets of toothed rings respectively mesh with two sets of chains 48. The other ends of the two sets of chains 48 respectively mesh with the outer rings of gear 44 and gear 47.
[0075] It should be noted that both gear 2 (42) and gear 3 (43) are bevel gears, designed to enable them to mesh in a perpendicular state.
[0076] Gear 5 45 meshes only with the upper half of gear 6 46, and the outer edges of both gear 5 45 and gear 6 46 are fitted (e.g., the pressure angle and module are the same) so that gear 5 45 can mesh smoothly with gear 6 46.
[0077] Preferably, to ensure that gear five 45 and gear six 46 can mesh smoothly, a conical friction component should be provided on the outer edge of gear six 46. Before meshing, the rotational speed of gear rod 32 should be reduced by a control element, thereby reducing the rotational speed of gear six 46. The purpose is that before gear five 45 and gear six 46 approach each other, gear five 45 can be driven to rotate by the conical friction device so that it can mesh with gear six 46 at the same rotational speed.
[0078] In this embodiment, during angle adjustment, motor 2 31 drives gear rod 32 to rotate, which in turn drives two sets of chains 48 to rotate. Chains 48 drive gears 44 and 47 to rotate. When gear 44 rotates, it drives gear 3 43 to rotate, which in turn drives gear 2 42 and lead screw 41 to rotate, controlling the lifting motion of lifting rod 34 so that roller 35 contacts lamp wick 16. When roller 35 descends to its position, gear 5 45 at its rear end meshes with gear 6 46. At this time, gear 7 47, driven to rotate by chain 48, drives gear 6 46 to rotate, which in turn drives gear 5 45 and roller 35 to rotate. The rotating roller 35 drives lamp wick 16 to rotate and adjust its angle. This achieves flexible adjustment of the orientation of lamp wick 16, meeting the lighting needs of different scenarios.
[0079] The working principle of this invention is as follows: During use, the temperature generated by the lamp wick 16 is transferred to the mounting ring 15, and then transferred to the heat pipe 13 and the heat-conducting plate 14 through the mounting ring 15. The heat-conducting plate 14 disperses the heat to the heat dissipation fins on the outer edge of the heat sink 11 to dissipate the heat. During angle adjustment, the second motor 31 drives the gear rod 32 to rotate, which in turn drives the two sets of chains 48 to rotate. The chains 48 drive the fourth gear 44 and the seventh gear 47 to rotate. When gear 44 rotates, it drives gear 3 43 to rotate, which in turn drives gear 2 42 and lead screw 41 to rotate. When lead screw 41 is driven to rotate in the forward direction, it drives lifting rod 34 to move downward and causes roller 35 to descend until the lower end of roller 35 contacts lamp wick 16. At this point, the lower end of lead screw 41 will disengage from the threaded groove of lifting rod 34 and will only be movably sleeved in rotating sleeve 37. Even if lead screw 41 continues to rotate, it cannot drive lifting rod 34 to descend further, thus avoiding excessive pressure from roller 35 on lamp wick 16, which could cause damage. When roller 35 descends to its final position, gear 5 45 at its rear end will mesh with gear 6 46. At this time, gear 7 47, driven to rotate by chain 48, will drive gear 6 46 to rotate, which in turn drives gear 5 45 and roller 35 to rotate. The rotating roller 35 is used to drive lamp wick 16 to rotate and adjust its angle. When a reset is needed, motor 21 drives lead screw 41 to rotate in the opposite direction. At this time, spring 36 pushes lifting rod 34 upward, connecting with the rotating lead screw 41, thus resetting lifting rod 34 and roller 35, disengaging them from contact with lamp wick 16, and avoiding affecting the adjustment of lamp wick 16's orientation. When the orientation of lamp wick 16 needs to be adjusted, motor 21 drives gear 22 to rotate, which in turn drives slip ring 23 to rotate through tooth groove 24, driving mounting ring 15 and lamp wick 16 to rotate together, thereby adjusting the orientation of lamp wick 16.
