Abstract

This invention provides a universal adjustable bracket and an LED spotlight with 360-degree adjustable light output. The universal adjustable bracket includes a retaining ring, an adjusting member, and a face ring. The adjusting member has an adjusting portion on its outer wall, which is spherically arc-shaped. The adjusting portion also has a hanging lug. The retaining ring has a clamping ring at its bottom and a first guiding arc surface on its inner ring surface. The retaining ring is connected to a first position on the inner ring surface of the face ring. The face ring has an adjusting groove at a second position and a second guiding arc surface at a third position. The first guiding arc surface of the retaining ring and the second guiding arc surface of the face ring combine in the inner ring of the face ring to form a spherical guiding arc surface for engagement with the adjusting portion of the adjusting member.

The clamping ring and the support tightly engage the hanging lug at the adjusting groove. This reduces the resistance during light source unit adjustment and improves the smoothness of adjustment.

Description

Technical Field

[0001] This invention relates to omnidirectional adjustment technology, and more particularly to an omnidirectional adjustment bracket and an LED spotlight that can adjust the light output by 360 degrees. Background Technology

[0002] Most ceiling spotlights currently on the market can only adjust the beam angle in one or two directions, which is inconvenient for users who need to adjust the beam angle in different directions.

[0003] To address this issue, existing technology CN 207179427 U proposed a downlight comprising a cover, a face ring, and a light source module. The outer surface of the light source module's housing is a truncated spherical surface. The cover and face ring are fixedly connected to form an inner cylinder with a truncated spherical surface. The light source module is placed inside this inner cylinder, and the cylinder wall of the inner cylinder fits snugly against the outer surface of the light source module's housing. The central plane of the light source module's housing in the vertical direction is on the same plane as the connection surface of the cover and face ring. This allows for free adjustment of the 360-degree illumination angle.

[0004] However, there is a problem with this type of structure that achieves 360-degree adjustment through a spherical arc surface (intercepting spherical curved surface). Since the spherical arc surface serves both as a guide and as a stop, it usually needs to form a certain interference fit. Otherwise, the adjusted angle is not easy to fix. However, although the angle fixation problem is solved, the disadvantage is that the close contact between the spherical arc surfaces causes a sharp increase in friction during adjustment, resulting in a poor adjustment feel, lack of smoothness, and strong resistance. Summary of the Invention

[0005] Therefore, the main objective of this invention is to provide a universal adjustable bracket and an LED spotlight that can adjust the light output by 360 degrees, so as to improve the defects of the prior art in the background art, thereby reducing the sense of resistance during universal adjustment and improving the smoothness of adjustment.

[0006] To achieve the above objectives, according to one aspect of the present invention, a universal adjustment bracket is provided, comprising: a retaining ring, an adjustment member, and a face ring, wherein the outer wall of the adjustment member is provided with an adjustment portion, which is spherical arc-shaped, and the adjustment portion is also provided with a hanging lug; the bottom of the retaining ring is provided with a clamping ring, and the inner ring surface is provided with a first guiding arc surface; wherein the retaining ring is connected to a first position on the inner ring surface of the face ring; a second position on the inner ring of the face ring is provided with an adjustment groove, and a third position is provided with a second guiding arc surface; wherein the first guiding arc surface of the retaining ring and the second guiding arc surface of the face ring are combined in the inner ring of the face ring to form a spherical guiding arc surface for holding the adjustment portion of the adjustment member; wherein the hanging lug of the adjustment member extends into the adjustment groove and abuts against the support of the adjustment groove; and the clamping ring and the support tightly engage the hanging lug at the adjustment groove.

[0007] In a possible preferred embodiment, the first guide arc surface and the second guide arc surface are provided with guide rings spaced at equal intervals. The first guide arc surface, the second guide arc surface, and the guide rings are combined in the inner ring of the face ring member to form a spherical guide arc surface ring array to hold the adjustment part of the adjustment member.

[0008] In a possible preferred embodiment, the hanging ear includes: a guide and an adjustment contact, wherein the guide is fixed to the adjustment part in a cylindrical shape, and the adjustment contact is disposed at a first position on the guide so that when the guide is inserted into the adjustment groove, the adjustment contact abuts against the support of the adjustment groove.

[0009] In a possible preferred embodiment, the clamping ring has a near-circular cross-section to press the guide tightly when the guide extends into the adjustment groove.

[0010] In a possible preferred embodiment, the adjustment groove is arranged in a ring shape at a second position on the inner ring of the face ring member.

[0011] To achieve the above objectives, according to another aspect of the present invention, an LED spotlight with 360-degree adjustable light output is also provided, comprising: a universal adjustment bracket and a light source unit, wherein the universal adjustment bracket is made of any of the universal adjustment bracket structures described above, and the light source unit is disposed on the adjustment member.

[0012] In a possible preferred embodiment, the light source unit includes: a heat sink and a light source module, wherein the heat sink has a first fastening part at its opening and an annular platform inside the heat sink to support at least part of the light source module therein, wherein the adjustment member has a light emission channel at its center and a second fastening part at its bottom, and the heat sink and the adjustment member are connected by the first fastening part and the second fastening part to hold the light source module in a sandwich shape, and the light emission direction of the light source module is oriented toward the light emission channel of the adjustment member.

[0013] In a possible preferred embodiment, the heat dissipation component includes: a heat dissipation shroud and an aluminum cup, wherein the bottom of the heat dissipation shroud is provided with an air vent, and the aluminum cup is mounted inside the heat dissipation shroud at the air inlet and outlet path of the air vent and supports the light source module, and the first fastening part is provided at the opening of the heat dissipation shroud.

[0014] The universal adjustable bracket and its 360-degree adjustable LED spotlight provided by this invention feature a hanging ear structure on the adjustment part. This design secures the light source unit within the face ring with the hanging ear as the axis, preventing it from falling off. Furthermore, the clamping ring tightly presses the hanging ear within the adjustment groove, ensuring stable fixation of the adjusted position of the light source unit. This eliminates the need for an interference fit between the spherical guide arc surface and the adjustment part, thus reducing the friction area and friction force during 360-degree universal adjustment (the contact area between the hanging ear, clamping ring, and adjustment groove support is smaller). This reduces resistance during adjustment, improves smoothness, and enhances the tactile experience. Additionally, the snap ring designed in this invention can be inserted from the front of the face ring, facilitating disassembly and assembly from the front of the light fixture, thus providing convenience for installation and subsequent maintenance.

(one)

[0035] Please refer to 1 to Figure 2 As shown, in order to reduce the resistance during universal adjustment and improve the smoothness of the adjustment, the present invention provides a universal adjustment bracket, which includes: a retaining ring 1, an adjustment member 22, and a face ring 3. The outer wall of the adjustment member 22 is provided with an adjustment part 21, which is in the shape of a spherical arc surface. The adjustment part 21 is also provided with a hanging ear 4. The bottom of the retaining ring 1 is provided with a pressing ring 11, the outer ring surface is provided with a first connecting part 12, and the inner ring surface is provided with a first guiding arc surface 13.

[0036] Furthermore, the inner ring of the face ring 3 is provided with a second connecting part 31 at the first position and an adjusting groove 32 at the second position. The adjusting groove 32 is arranged in a ring shape at the second position and a second guiding arc surface 33 at the third position of the inner ring of the face ring. When the adjusting member 22 is engaged with the face ring 3, the adjusting member 22 extends into the adjusting groove 32 through the hook 4 and abuts against the bottom wall of the adjusting groove 32, i.e., the support 34, so that the adjusting member 22 is placed in the inner ring of the face ring 3. In this example, as shown... Figure 2 As shown, the hanging ear 4 preferably includes: a guide 41 and an adjustment contact 42, wherein the guide 41 is fixed on the adjustment part 21 in a cylindrical shape, and the adjustment contact 42 is disposed at a first position of the guide 41, such as the bottom of the guide 41, so that when the guide 41 extends into the adjustment groove 32, the adjustment contact 42 can abut against the support 34 of the adjustment groove 32.

[0037] On the other hand, the retaining ring 1 is snapped together with the second connecting part 31 of the inner ring surface of the face ring 3 via the first connecting part 12, so as to be fixed at the first position of the inner ring surface of the face ring 3.

[0038] Meanwhile, it is worth mentioning that when the retaining ring 1 is fixed at the first position of the inner ring of the face ring 3, on the one hand, the first guide arc surface 13 and the second guide arc surface 33 can be combined in the inner ring of the face ring 3 to form a spherical guide arc surface, so as to form a non-interference fit with the spherical arc surface of the adjusting part 21 of the adjusting part 22, so as to allow the adjusting part 21 to move smoothly in 360 degrees within the guiding range of the spherical guide arc surface. On the other hand, the clamping ring 11 will also press the hanging ear 4 tightly in the adjusting groove 32, thereby fixing the adjusting position of the adjusting part 22.

[0039] Furthermore, in order to further reduce the contact area between the clamping ring 11 and the guide 41 and reduce the feeling of resistance, in this example, the clamping ring 11 is designed as a ring with a near-circular cross-section. Thus, when the guide 41 is inserted into the adjustment groove 32 and pressed by it, the contact formed between the guide 41 and the clamping ring 11 is a point-to-point contact, which can greatly reduce friction and reduce the feeling of resistance.

[0040] It is evident that the design structure of this case abandons the traditional method of using an interference fit between a spherical arc surface and a spherical guide arc surface to achieve 360-degree omnidirectional angle adjustment and fixation. Instead, it uses the lug 4 to perform the function of fixing the angle. Through the point-to-surface contact between the adjustment contact 42 of the lug 4 and the support 34, as well as the point-to-point contact structure between the clamping ring 11 and the guide 41, the frictional resistance can be greatly reduced, thereby improving the smoothness of adjustment, reducing the feeling of resistance, and thus improving the feel of adjustment.

[0041] On the other hand, please see Figure 10 As shown, to further improve the smoothness of adjustment and reduce resistance, in a preferred embodiment, the first guide arc surface 13 and the second guide arc surface 33 are further provided with equidistant guide rings 5. The first guide arc surface 13, the second guide arc surface 33, and the guide rings 5 ​​are combined in the inner ring of the surface ring member 3 to form a spherical guide arc surface ring array, which is used to engage with the adjustment part 21 of the adjustment member 22 to hold the adjustment member 22. By engaging the adjustment part 21 of the adjustment member 22 with the spherical guide arc surface ring array, the contact area between the two is reduced, thereby reducing frictional resistance, improving the smoothness of adjustment, reducing resistance, and thus improving the feel during adjustment. (two)

[0043] Please refer to 3 to Figure 10As shown, another aspect of the present invention provides an LED spotlight with 360-degree adjustable light output, which includes: a universal adjustment bracket and a light source unit 2, wherein the universal adjustment bracket can be made of the universal adjustment bracket structure as described in Embodiment 1, and the light source unit 2 can be disposed on the adjustment member 22.

[0044] Specifically, such as Figure 5 , Figure 6 As shown, in this example, the light source unit 2 preferably includes: a heat sink 23 and a light source module 24. The heat sink 23 has a first fastening portion 25 at its opening and an annular platform inside to support at least a portion of the light source module 24. The adjusting member 22 has a light emission channel 27 at its center and a second fastening portion 26 at its bottom. The heat sink 23 and the adjusting member 22 are connected by a fastening connection between the first fastening portion 25 and the second fastening portion 26, holding the light source module 24 in a sandwich configuration, with the light emission direction of the light source module 24 facing the light emission channel 27 of the adjusting member 22. In this example, the light source module 24 has a conventional structure, consisting of optical lenses, LED light source particles, and a driver, among other components.

[0045] In a preferred embodiment, to further improve the heat dissipation effect, the heat dissipation component 23 includes: a heat dissipation cover 231 and an aluminum cup 232. The heat dissipation cover 231 has an air vent 233 at its bottom, and the aluminum cup 232 is mounted on an annular platform inside the heat dissipation cover 231 to support the light source module 24. The first fastening part 25 is provided at the opening of the heat dissipation cover 231 so that the heat dissipation cover 231 and the bottom of the adjusting member 22 are fastened together to hold the light source module 24 in a sandwich shape. This directs the working heat of the light source module 24 to the aluminum cup 232 and introduces air cooling through the air vent 233 of the heat dissipation cover 231, thereby stabilizing the working temperature of the light source module 24.

[0046] Furthermore, the inner ring of the face ring 3 is provided with a second connecting part 31 at the first position and an adjusting groove 32 at the second position. The adjusting groove 32 is arranged in a ring shape at the second position and a second guiding arc surface 33 at the third position of the inner ring of the face ring. When the light source unit 2 is mated with the face ring 3, the light source unit 2 extends into the adjusting groove 32 through the hook 4 and abuts against the bottom wall of the adjusting groove 32, i.e., the support 34, so that the light source unit 2 is placed in the inner ring of the face ring 3. In this example, as shown... Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the hanging ear 4 preferably includes: a guide 41 and an adjustment contact 42, wherein the guide 41 is fixed on the adjustment part 21 in a cylindrical shape, and the adjustment contact 42 is disposed at a first position of the guide 41, such as the bottom of the guide 41, so that when the guide 41 extends into the adjustment groove 32, the adjustment contact 42 can abut against the support 34 of the adjustment groove 32.

[0047] On the other hand, the retaining ring 1 is snapped together with the second connecting part 31 of the inner ring surface of the face ring 3 via the first connecting part 12, so as to be fixed at the first position of the inner ring surface of the face ring 3.

[0048] Meanwhile, it is worth mentioning that when the retaining ring 1 is fixed at the first position of the inner ring of the face ring 3, on the one hand, the first guiding arc surface 13 and the second guiding arc surface 33 can be combined in the inner ring of the face ring 3 to form a spherical guiding arc surface, so as to form a non-interference fit with the spherical arc surface of the adjustment part 21 of the light source unit 2, so as to allow the adjustment part 21 to move smoothly in 360 degrees within the guiding range of the spherical guiding arc surface. On the other hand, the clamping ring 11 will also press the hanging ear 4 tightly in the adjustment groove 32, thereby fixing the adjustment position of the light source unit 2.

[0049] Furthermore, in order to further reduce the contact area between the clamping ring 11 and the guide 41 and reduce the feeling of resistance, in this example, the clamping ring 11 is designed as a ring with a near-circular cross-section. Thus, when the guide 41 is inserted into the adjustment groove 32 and pressed by it, the contact formed between the guide 41 and the clamping ring 11 is a point-to-point contact, which can greatly reduce friction and reduce the feeling of resistance.

[0050] It is evident that the design structure of this case abandons the traditional method of using an interference fit between a spherical arc surface and a spherical guide arc surface to achieve 360-degree omnidirectional angle adjustment and fixation. Instead, it uses the lug 4 to perform the function of fixing the angle. Through the point-to-surface contact between the adjustment contact 42 of the lug 4 and the support 34, as well as the point-to-point contact structure between the clamping ring 11 and the guide 41, the frictional resistance can be greatly reduced, thereby improving the smoothness of adjustment, reducing the feeling of resistance, and thus improving the feel of adjustment.

[0051] On the other hand, please see Figure 10As shown, to further improve the smoothness of adjustment and reduce the feeling of resistance, in a preferred embodiment, the first guide arc surface 13 and the second guide arc surface 33 are further provided with equidistant guide rings 5. The first guide arc surface 13, the second guide arc surface 33, and the guide rings 5 ​​are combined in the inner ring of the surface ring member 3 to form a spherical guide arc surface ring array, which is used to engage with the adjustment part 21 of the light source unit 2 to hold the adjustment member 22. By engaging the adjustment part 21 of the light source unit 2 with the spherical guide arc surface ring array, the contact area between the two is reduced, thereby reducing frictional resistance, improving the smoothness of adjustment, reducing the feeling of resistance, and thus improving the feel of adjustment.

[0052] In summary, the universal adjustable bracket and the 360-degree adjustable LED spotlight provided by this invention feature a hanging ear structure on the adjustment part. This design secures the light source unit within the face ring with the hanging ear as its axis, preventing it from easily falling off. Furthermore, the clamping ring tightly presses the hanging ear within the adjustment groove, ensuring a stable fixation of the adjusted position of the light source unit. This eliminates the need for an interference fit between the spherical guide arc surface and the adjustment part, thereby reducing the friction area and friction force during 360-degree universal adjustment (the contact area between the hanging ear, the clamping ring, and the adjustment groove support is smaller). This reduces resistance during adjustment, improves smoothness, and enhances the tactile experience. Additionally, the snap ring designed in this invention can be inserted from the front of the face ring, facilitating disassembly and assembly from the front of the light fixture, thus providing convenience for installation and subsequent maintenance.
