[0002] In the field of modern lighting, wall lamps are a common lighting device and are widely used in various environments such as homes, commercial places, hotels, corridors, etc. LED wall lamps have gradually replaced traditional wall lamps due to their advantages such as energy saving, high brightness and long life.

[0003] However, existing LED wall lamps have certain limitations in actual use. In many scenarios, the fixed lighting angle cannot meet the diverse lighting needs of users. Traditional wall lamps, whether through a simple lampshade design or a fixed lamp body structure, are difficult to achieve free adjustment of the angle. Although some wall lamps can be set to a certain degree of angle during installation, they cannot be easily adjusted again during subsequent use. This limitation prevents users from optimizing the lighting effect according to actual conditions during use, reduces the user experience, and also limits the application of LED wall lamps in some special scenarios with high requirements for lighting angles. Therefore, it is necessary to develop an adjustable angle LED wall lamp that can solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] See also Figures 1-4An angle-adjustable LED wall lamp comprises a mounting base 1, a housing 2 is fixedly connected to the end surface of the mounting base 1, a collar 3 is provided inside the housing 2, an annular ball groove 4 is provided on the end surface of the collar 3, a ball 5 is rolled in contact with the inside of the annular ball groove 4, an L-shaped rod 6 is rotatably connected to the spherical surface of the ball 5, one end of the L-shaped rod 6 is fixedly connected to a sleeve 7, the inside of the sleeve 7 is connected to a shaft rod 8, one end of the shaft rod 8 is fixedly connected to a C-shaped frame 9, and the outer surface of the shaft rod 8 is rotatably connected to a central connecting rod 10, and the bottom end of the central connecting rod 10 is fixedly connected to the It is connected to a worm gear 11, which is transmission-connected to a worm 12. Both ends of the worm 12 are fixedly connected to a rotating rod 13, one end of the rotating rod 13 is fixedly connected to a knob 14, and the outer surface of the collar 3 is connected to a connecting ear 15. A screw 16 is fixedly connected to the end face of the mounting base 1 near the edge, and the outer surface of the screw 16 is threadedly connected to a knob 2 17. A vertical groove 18 is provided on the outer surface of the housing 2, and a spring 19 is sleeved on the outer surface of the screw 16. A support rod 20 is fixedly connected to the center of the end face of the worm gear 11, and the outer surface of the support rod 20 is rotatably connected to a connecting plate 21.

[0028] Specifically, a square hole is formed on the outer surface of the C-shaped frame 9, into which a connecting rod 22 is inserted. One end of the connecting rod 22 is fixedly connected to the wall lamp body 23. Advantageously, the connecting rod 22 includes a block disposed on its outer surface that can be inserted into the square hole of the C-shaped frame 9. Furthermore, the connecting rod 22 has threads on its outer surface that fit with a nut for fixed connection to the C-shaped frame 9. This allows the C-shaped frame 9 to be connected to the wall lamp body 23. By removing the nut on the connecting rod 22, the wall lamp body 23 can be removed, making it convenient to remove and repair the wall lamp body 23 in the event of a malfunction.

[0029] Specifically, the outer surface of the housing 2 is provided with a hole through which a rotating rod 13 passes. One end of the rotating rod 13 is rotatably connected to the inner wall of the housing 2. Advantageously, turning the knob 14 drives the rotating rod 13, which in turn drives the worm 12, which in turn drives the worm gear 11, which in turn drives the central connecting rod 10, which in turn drives the shaft 8, which in turn drives the C-shaped frame 9, which in turn drives the connecting rod 22, which in turn drives the wall lamp body 23.

In this way, with the cooperation of the spring 19, the movement of the second knob 17 can drive the ear 15 to move, and then drive the collar 3 to move. Because the ball 5 rolls in contact with the inside of the annular ball groove 4, when the collar 3 moves, it can drive the ball 5, which in turn drives the L-shaped rod 6, which in turn drives the sleeve 7 to rotate, the sleeve 7 drives the shaft 8 to rotate, and the shaft 8 drives the C-shaped frame 9 to rotate, ultimately, the angular position of the wall lamp body 23 can be adjusted around the axis of the shaft 8.

[0031] Example 2:

[0032] See also Figure 1 As shown, as an improvement to the previous embodiment.

Advantageously, the entire device can be mounted on a wall by inserting matching bolts through the mounting holes of mounting base 1. The spring 19 maintains a constant resistance against lug 15, so that when knob 2 17 is adjusted in the direction away from mounting base 1, spring 19 pushes against lug 15, thereby moving collar 3.

[0034] Specifically, the end of the support rod 20 away from the worm gear 11 is rotatably connected to the mounting base plate 1, the sleeve 7 is connected to the outer surface of the shaft 8 via a screw, a scale line is engraved on one side of the vertical slot 18, and the two ends of the connecting plate 21 are connected to the inner wall of the housing 2. The advantage is that when adjusting the second knob 17, the scale line engraved next to the vertical slot 18 can be used to know the moving position of the lug 15. This ensures that the two lugs 15 move to the same position, which ensures that the collar 3 can move smoothly. Because the synchronized position of the lugs 15 ensures that the collar 3 is evenly stressed, it can avoid device jamming caused by uneven stress.

[0035] When in use, first, use the matching bolts to pass through the mounting holes of the mounting base plate 1 to install the entire device on the wall; secondly, when it is necessary to adjust the angle of the wall lamp body 23 around the central connecting rod 10, turn the knob 14, the knob 14 drives the rotating rod 13 to rotate, the rotating rod 13 drives the worm 12 to rotate, the worm 12 drives the worm gear 11 to rotate, the worm gear 11 drives the central connecting rod 10 to rotate, the central connecting rod 10 drives the shaft rod 8 to rotate, the shaft rod 8 drives the C-shaped frame 9 to rotate, the C-shaped frame 9 drives the connecting rod 22 to rotate, and the connecting rod 22 drives the wall lamp body 23 to rotate; when it is necessary to adjust the angle around the axial direction of the shaft rod 8, When adjusting the angle of the wall lamp body 23, turn the knob 2 17, and the knob 2 17 moves on the outer surface of the screw 16, and drives the ear 15 to move with the cooperation of the spring 19, and the ear 15 drives the ring 3 to move, and the ring 3 drives the shaft 8 to rotate through a series of transmissions such as the ball 5, the L-shaped rod 6, and the sleeve 7, and the shaft 8 drives the C-shaped frame 9 to rotate, and finally adjusts the angle of the wall lamp body 23. During the adjustment process, the scale line on one side of the vertical groove 18 can be used to ensure that the two ears 15 move to the same position; finally, when the wall lamp body 23 fails, remove the nut on the connecting rod 22 and remove the wall lamp body 23 from the C-shaped frame 9 for maintenance.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
