Description

Technical Field

[0001] This utility model relates to an LED wall washer lighting device, specifically an LED linear wall washer lighting device with adjustable arc on a flexible substrate, belonging to the field of LED wall washer lighting technology. Background Technology

[0002] LED wall washer lights, as the name suggests, make light wash over the wall like water. They are mainly used for architectural decorative lighting and to outline the contours of large buildings. Because LEDs have the characteristics of energy saving, high luminous efficiency, rich colors and long life, other light sources of wall washer lights are gradually being replaced by LED wall washer lights.

[0003] Chinese Patent Publication CN218671880U discloses an LED wall washer lighting device. During operation, a power supply assembly powers the motor and LED beads. The motor drives a pivot shaft to rotate, causing a drive block to swing. During this swing, the drive block can contact and then separate from the extension portion. Combined with the elastic force of the first and second tension springs, the lamp holder can cause the LED beads to oscillate slightly, forming a movable light source. Compared to traditional methods, this invention sets the light source to be able to oscillate slightly, increasing the diversity of light sources for the LED wall washer and effectively improving the illumination effect.

[0004] The aforementioned patented LED wall washer lighting device uses a fixed LED substrate, lacking flexible adjustment space. This means that once the device is securely mounted on the wall, the illumination arc cannot be fine-tuned to accommodate tilting caused by on-site construction errors. Consequently, the wall washer lighting effect is poor, impacting its overall performance. Therefore, this paper proposes a flexible substrate, adjustable arc LED linear wall washer lighting device. Utility Model Content

[0005] This invention proposes a flexible substrate adjustable arc LED linear wall washer lighting device to solve the problem that existing LED wall washer lighting devices cannot fine-tune the illumination arc of the LED wall washer lighting device according to installation errors, resulting in poor wall washer lighting effect on the wall.

[0006] This utility model is achieved through the following technical solution: a flexible substrate adjustable arc LED linear wall washer lighting device, including a housing, a lampshade is snapped onto the upper surface of the housing, and an adjustment mechanism is provided inside the housing;

[0007] The adjustment mechanism includes several fixed plates, all of which are disposed inside the housing. Flexible rubber plates are fixedly connected to one side of each fixed plate that is close to the other. LED beads are fixedly connected to the upper surface of each fixed plate. A first bidirectional screw is disposed below each fixed plate. Each first bidirectional screw is rotatably connected inside the housing. A first adjustment frame is engaged with the outer surface of each first bidirectional screw. The upper surface of each first adjustment frame is slidably connected to the bottom surface of the fixed plate. Several rotating rods are rotatably connected inside the housing. Pulleys are fixedly connected to the outer surfaces of the rotating rods and the outer surfaces of each first bidirectional screw. A synchronous belt is connected to the outer surfaces of every two pulleys for transmission.

[0008] A stabilizing component is provided below several of the fixed plates, and a fine-tuning component is provided below the housing.

[0009] The stabilizing component includes several limiting posts, both ends of which are fixedly connected to the inner wall of the housing. These limiting posts are rotatably connected to the interior of a fixed plate. A second bidirectional screw is provided below each of the fixed plates. The outer surface of each second bidirectional screw is rotatably connected to the interior of the housing. A second adjusting bracket is threaded onto the outer surface of each second bidirectional screw. The upper surface of each second adjusting bracket is slidably connected to the bottom surface of the fixed plate. A first gear is fixedly connected to the outer surface of each second bidirectional screw. A second gear is fixedly connected to the outer surface of each rotating rod. Each second gear meshes with the first gear.

[0010] Each of the outer surfaces of the first bidirectional screw and the second bidirectional screw is rotatably connected to a stabilizing seat, and the bottom surface of each stabilizing seat is fixedly connected to the inner bottom wall of the housing.

[0011] Each of the rotating rods has a positioning seat rotatably connected to its outer surface, and the bottom surface of each positioning seat is fixedly connected to the inner bottom wall of the housing.

[0012] The fine-tuning component includes two fixing brackets, the upper surfaces of which are fixedly connected to the bottom surface of the housing, and mounting brackets are provided below each of the two fixing brackets. Gear discs are fixedly connected to the inner walls of the two fixing brackets and the inner walls of the two mounting brackets. The inner walls of the two fixing brackets and the inner walls of the two mounting brackets are connected by two fixing bolts through a common thread.

[0013] Both mounting brackets have nuts inside, and the inner walls of the two nuts are threadedly connected to the outer surfaces of the two fixing bolts.

[0014] This utility model provides an LED linear wall washer lighting device with adjustable arc on a flexible substrate, which has the following beneficial effects:

[0015] 1. This flexible substrate adjustable-arc LED linear wall washer lighting device, through the rotation of the rotating rod and pulley, can drive the first bidirectional screw to rotate. When the first bidirectional screw rotates, the special bidirectional thread on the first bidirectional screw can drive the first adjusting frame to fold or open. In conjunction with the sliding connection between the first adjusting frame and the fixed plate, it can drive one side of the fixed plate to swing up and down. With the assistance of the stabilizing component, the illumination arc of multiple LED beads can be adjusted individually. In addition, the flexible rubber plate can increase the connection between multiple fixed plates and protect the wires to a certain extent. It can prevent the wires from being excessively bent during the adjustment of the illumination arc of the fixed plate and LED beads, which would affect the power supply effect. This gives the LED wall washer lighting device flexible adjustment space during use, allowing the LED wall washer lighting device to fine adjust the illumination arc of the LED wall washer lighting device according to the tilt caused by on-site construction errors, so as to ensure the wall washer lighting effect of the LED wall washer lighting device.

[0016] 2. The flexible substrate adjustable arc LED linear wall washer lighting device, through the fine-tuning component, can finely adjust the overall elevation angle of the housing after it is installed on the wall as needed. This allows the LED wall washer lighting device to adjust the illumination elevation angle according to the on-site installation requirements during use, further improving the illumination arc adjustment range of the LED wall washer lighting device and enabling it to achieve better wall washer lighting effect.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0029] Please see Figures 1-5 This utility model provides a flexible substrate adjustable arc LED linear wall washer lighting device, including a housing 1, a lampshade 2 snapped onto the upper surface of the housing 1, and an adjustment mechanism 3 provided inside the housing 1;

[0030] The adjustment mechanism 3 includes several fixed plates 301, all of which are located inside the housing 1. Flexible rubber plates 302 are fixedly connected to the sides of the fixed plates 301 that are close to each other. LED beads 303 are fixedly connected to the upper surfaces of the fixed plates 301. First bidirectional screws 304 are provided below each of the fixed plates 301. Each first bidirectional screw 304 is rotatably connected inside the housing 1. A first adjustment frame 305 is engaged with the outer surface of each first bidirectional screw 304. The upper surface of each first adjustment frame 305 is slidably connected to the bottom surface of the fixed plate 301. Several rotating rods 306 are rotatably connected inside the housing 1. A positioning seat 407 is rotatably connected to the outer surface of each rotating rod 306. The bottom surface of each positioning seat 407 is fixedly connected to the inner bottom wall of the housing 1. The positioning seat 407 can further position the rotating rod 306, preventing it from becoming loose from the housing 1 during use and ensuring the reliability of the rotation of the rotating rod 306.

[0031] Please refer to this carefully. Figure 3 and Figure 4The outer surfaces of several rotating rods 306 and the outer surface of each first bidirectional screw 304 are fixedly connected to pulleys 307, and the outer surfaces of every two pulleys 307 are connected to a synchronous belt 308 for transmission.

[0032] A stabilizing assembly 4 is provided below several fixed plates 301. The stabilizing assembly 4 includes several limiting posts 401, both ends of which are fixedly connected to the inner wall of the housing 1. The limiting posts 401 are rotatably connected to the inside of the fixed plates 301. A second bidirectional screw 402 is provided below each of the fixed plates 301. The outer surface of each second bidirectional screw 402 is rotatably connected to the inside of the housing 1. A second adjusting bracket 403 is threadedly connected to the outer surface of each second bidirectional screw 402. The upper surfaces of the second adjusting brackets 403 are slidably connected to the bottom surface of the fixed plate 301. The tops of the first adjusting brackets 305 and the second adjusting brackets 403 are both bidirectional movable hinge structures. This, combined with the sliding of the tops of the first adjusting brackets 305 and the second adjusting brackets 403 within the fixed plate 301, ensures that while the side of the fixed plate 301 is tilted up for arc adjustment, it can simultaneously adapt to multi-directional angle changes during the arc adjustment process, allowing the fixed plate 301 to complete the adjustment smoothly. Each second double... A first gear 404 is fixedly connected to the outer surface of each screw 402, and a second gear 405 is fixedly connected to the outer surface of each rotating rod 306. Each second gear 405 meshes with the first gear 404. When the rotating rod 306 rotates, it drives the synchronous belt 308 and the first bidirectional screw 304 to rotate clockwise through the pulley 307. The rotating rod 306 can also drive the second bidirectional screw 402 to rotate counterclockwise through the meshing of the first gear 404 and the second gear 405, causing the first adjusting frame 305 to close and push the fixed... When the right side of the fixed plate 301 moves upward along the axis of the limiting post 401, the counterclockwise rotation of the second bidirectional screw 402 causes the second adjusting frame 403 to separate and move the left side of the fixed plate 301 downward along the axis of the limiting post 401. This ensures that the fixed plate 301 can be smoothly adjusted in arc. By providing the first adjusting frame 305 and the second adjusting frame 403 on both sides of the fixed plate 301, the stability of the fixed plate 301 after angle adjustment can be effectively guaranteed, making it less likely for the fixed plate 301 to loosen after angle adjustment.

[0033] Please refer to this carefully. Figure 3 Each first bidirectional screw 304 and each second bidirectional screw 402 is rotatably connected to a stabilizing seat 406 on its outer surface. The bottom surface of each stabilizing seat 406 is fixedly connected to the inner bottom wall of the housing 1. The stabilizing seat 406 can further stabilize the position of the first bidirectional screw 304 and the second bidirectional screw 402, making the first bidirectional screw 304 and the second bidirectional screw 402 more stable and reliable when working.

[0034] Please refer to this carefully. Figure 2 and Figure 5 A fine-tuning component 5 is provided at the bottom of the housing 1. The fine-tuning component 5 includes two fixing brackets 501. The upper surfaces of the two fixing brackets 501 are fixedly connected to the bottom surface of the housing 1. A mounting bracket 502 is provided below each of the two fixing brackets 501. A gear plate 503 is fixedly connected to the inner walls of the two fixing brackets 501 and the two mounting brackets 502. The inner walls of the two fixing brackets 501 and the two mounting brackets 502 are connected by two fixing bolts 504 through threads. The mounting bracket 502 is first fixed to the wall using the mounting holes on it. Then, the overall elevation angle of the housing 1 is finely adjusted as needed, so that the LED wall washer lighting device can adjust the illumination elevation angle according to the on-site installation needs during use, further improving the illumination arc adjustment range of the LED wall washer lighting device, so that it can achieve a better wall washing illumination effect. Then, by tightening the fixing bolts 504, the mounting bracket 502 is forced to be close to the fixing bracket 501. At this time, the toothed disc 503 on the mounting bracket 502 and the toothed disc 503 on the fixing bracket 501 will mesh with each other, thereby ensuring the stability of the housing 1 after the elevation angle is adjusted.

[0035] Please refer to this carefully. Figure 5 Both mounting brackets 502 have nuts 505 inside, and the inner walls of the two nuts 505 are threaded to the outer surfaces of the two fixing bolts 504 respectively. By locking the nuts 505 inside the mounting brackets 502, the locking firmness of the fixing bolts 504 to the mounting brackets 502 and the fixing brackets 501 can be increased, making it less likely for the fixing bolts 504 to loosen during use.

[0036] When using this utility model: First, use the mounting holes on the mounting bracket 502 to fix the mounting bracket 502 to the wall. Then, make a fine adjustment to the overall elevation angle of the housing 1 as needed. This allows the LED wall washer lighting device to adjust the illumination elevation angle according to the on-site installation needs, further improving the illumination arc adjustment range of the LED wall washer lighting device and enabling it to achieve a better wall washer lighting effect. Then, by tightening the fixing bolt 504 and locking it with the nut 505, the mounting bracket 502 is forced to be close to the fixing bracket 501. At this time, the toothed disc 503 on the mounting bracket 502 and the toothed disc 503 on the fixing bracket 501 will mesh with each other, thereby ensuring the stability of the housing 1 after the elevation angle is adjusted.

[0037] Then, by rotating the rotating rod 306 in conjunction with the pulley 307 and the positioning seat 407, the first bidirectional screw 304 can be driven to rotate. When the first bidirectional screw 304 rotates, the special bidirectional thread on the first bidirectional screw 304 can drive the first adjusting frame 305 to fold or open. In conjunction with the bidirectional movable hinge structure at the top of the first adjusting frame 305 and the sliding connection between the bidirectional movable hinge structure at the top of the first adjusting frame 305 and the fixed plate 301, one side of the fixed plate 301 can be driven to swing up and down, realizing the movement of multiple LED beads 30. The illumination arc of LED wall washer light can be adjusted independently. In addition, the flexible rubber plate 302 can increase the connection between multiple fixing plates 301 and protect the wires to a certain extent. It can also prevent the wires from being excessively bent when the illumination arc of the fixing plate 301 and LED lamp beads 303 is adjusted, which would affect the power supply effect. This allows the LED wall washer light device to have flexible adjustment space during use. It can also make fine adjustments to the illumination arc of the LED wall washer light device according to the tilt caused by the on-site construction error, thus ensuring the wall washer light device's wall washer lighting effect.

[0038] Finally, when the rotating rod 306 rotates and drives the synchronous belt 308 and the first bidirectional screw 304 to rotate clockwise through the pulley 307, the rotating rod 306 can also drive the second bidirectional screw 402 to rotate counterclockwise through the meshing of the first gear 404 and the second gear 405. This causes the first adjusting frame 305 to close and push the right side of the fixed plate 301 to move upward along the axis of the limiting post 401. At the same time, the counterclockwise rotation of the second bidirectional screw 402 causes the second adjusting frame 403 to separate and drive the left side of the fixed plate 301 to move downward along the axis of the limiting post 401. Thus, while ensuring that the fixed plate 301 can be smoothly adjusted in arc, the first adjusting frame 305 and the second adjusting frame 403 are respectively set on both sides of the fixed plate 301, which can effectively ensure the stability of the fixed plate 301 after angle adjustment and prevent the fixed plate 301 from becoming loose after angle adjustment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
