An angle-adjustable down lamp

Abstract

This utility model relates to the field of lighting technology, specifically to an angle-adjustable downlight, including a lamp body and an illumination component disposed within the lamp body. An inner support is also provided within the lamp body, and a rotating component is provided between the lamp body and the inner support. The inner support can rotate circumferentially around the lamp body via the rotating component. A connecting rod is provided on the inner support, and the illumination component is connected to the inner support via the connecting rod. The illumination component can swing about the connecting rod as a pivot to adjust the illumination angle. Because the illumination component can swing about the connecting rod as a pivot, its tilt angle can be changed. As the illumination component swings, the position of the light emitted by the illumination component changes accordingly. Since the illumination component is connected to the inner support, when the inner support rotates circumferentially around the lamp body via the rotating component, the illumination component rotates synchronously, causing the horizontal illumination position of the light to change depending on the direction of rotation.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] This embodiment provides an angle-adjustable downlight, such as... Figures 1 to 6 As shown, the lamp includes a lamp body 1 and an illumination component 3 disposed within the lamp body 1 for emitting light. An inner support 2 is also provided inside the lamp body 1, and a rotating assembly is provided between the lamp body 1 and the inner support 2, allowing the inner support 2 to rotate circumferentially along the lamp body 1 via the rotating assembly. A connecting rod 21 is provided on the inner support 2, and the illumination component 3 is connected to the inner support 2 via the connecting rod 21. The illumination component 3 can swing about the connecting rod 21 as a pivot to adjust the illumination angle of the illumination component 3.

[0025] Specifically, an arc-shaped extension plate 20 is provided at the top of the inner support 2, and the connecting rod 21 is provided on the inner side wall of this extension plate 20.

[0026] This design allows the lighting component 3 to swing around the connecting rod 21, thus changing its tilt angle. As the lighting component 3 swings, the position of the light emitted changes accordingly, no longer limited to a fixed area directly below the lamp, but extending to other areas such as the sides, depending on the tilt angle. Furthermore, since the lighting component 3 is connected to the inner support 2, when the inner support 2 rotates circumferentially along the lamp body 1 via the rotating component, the lighting component 3 rotates synchronously, causing the horizontal illumination position of the light to change with the direction of rotation. Compared to existing technologies, this application achieves the change of illumination angle without rotating the lamp body 1.

[0027] Furthermore, the rotating assembly includes an annular groove 10 on the inner wall of the lamp body 1 and an extension block 23 on the outer wall of the inner support 2. An extension rod 24 is provided on the extension block 23 and is inserted into the extension block 23. A ball bearing 25 is embedded at the end of the extension rod 24 away from the extension block 23. The ball bearing 25 is engaged in the annular groove 10 and can roll along the annular groove 10.

[0028] It should be noted that there are multiple extension blocks 23, which are evenly distributed along the outer wall of the inner support 2. Each extension block 23 is provided with a corresponding extension rod 24 and a ball bearing 25. This design allows the inner support 2 to rotate more smoothly within the lamp body 1, avoiding jamming or tilting, and ensuring that the lighting component 3 maintains a stable posture when rotating with the inner support 2.

[0029] To prevent the inner support 2 from rotating excessively around the lamp body 1, a stop plate 11 is provided inside the lamp body 1. A stop plate 22, which engages with the stop plate 11, is provided on the inner support 2. The stop plate 22 is located on the outer wall of the extension plate 20, with its vertical height exceeding the height of the extension block 23. Through the engagement of the stop plate 11 and the stop plate 22, the rotation angle of the inner support 2 can be controlled within ±350°, preventing the inner support 2 from causing the lighting component 3 to rotate excessively and thus breaking the wires connected to the lighting component 3.

[0030] Furthermore, the lighting assembly 3 includes an inner housing 30, a reflector 32, a lens 33, a light source mounting bracket 34, and an LED light panel 35. The reflector 32 is housed within the inner housing 30, while the lens 33 is located within the reflector 32. The reflector 32 and lens 33 work together to process the light emitted from the LED light panel 35 to improve light quality. The specific principles of the reflector 32 and lens 33 are the same as in existing technologies and will not be elaborated further here.

[0031] The light source mounting bracket 34 is fixedly mounted on top of the reflector cup 32 by snap-fit ​​or bolts to prevent it from shifting off the top of the inner housing 30 when the lighting assembly 3 tilts. An embedding groove is provided on the top of the light source mounting bracket 34, into which the LED light board 35 is embedded. The embedding groove positions and fixes the LED light board 35, preventing it from shifting during use when the lighting assembly 3 tilts, thus ensuring the relative position of the LED light board 35 with the light source mounting bracket 34 and the reflector cup 32 remains stable.

[0032] The connecting rod 21 on the inner support 2 is connected to the inner housing 30 in the lighting assembly 3. Specifically, the inner housing 30 is provided with a connecting hole 31 corresponding to the position of the connecting rod 21. The end of the connecting rod 21 away from the inner support 2 is inserted into the connecting hole 31 to realize the connection between the lighting assembly 3 and the inner support 2.

[0033] Furthermore, the lighting assembly 3 also includes a base and a heat sink 37. The support plate 36 is located at the bottom of the inner housing 30 and is threadedly connected to the inner housing 30, and is used to support the reflector cup 32, the light source mounting bracket 34 and the LED light panel 35. The heat sink 37 is located at the top of the inner housing 30 and is threadedly connected to the inner housing 30, and is used to dissipate heat from the LED light panel 35.

[0034] Furthermore, the downlight also includes a cover plate 4, which is located on the top of the lamp body 1. The downlight can be installed at a designated location via the cover plate 4. Specifically, the cover plate 4 is rotatably engaged with the lamp body 1. The cover plate 4 has a retaining edge 40 on its edge, and the inner wall of the lamp body 1 has retaining blocks 12 arranged vertically at intervals. A retaining groove 13 is formed between two retaining blocks 12 to engage the retaining edge 40.

[0035] In addition, a mounting notch 41 is provided between one end of the clip 40 and the cover plate 4. The size of this mounting notch 41 is slightly larger than the gear of the clip block 12. By setting the mounting notch 41, when it is necessary to remove the lamp body 1 from the cover plate 4, first rotate the cover plate 4 so that the mounting notch 41 on the cover plate 4 aligns with the clip block 12 above, and then move the lamp body 1 down or lift the cover plate 4 up.

[0036] The other end of the retaining edge 40 forms a limiting part 42 between the cover plate 4 and the retaining edge 4. By setting the retaining part 42, when the cover plate 4 and the lamp body 1 rotate relative to each other to a certain angle, the retaining part 42 will abut against the retaining block 12 on the inner wall of the lamp body 1, thereby limiting the two from continuing to rotate and preventing the wires inside the lamp from being twisted off due to excessive rotation.
