Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and more specifically to an angle adjustment structure for a spotlight. Background Technology

[0002] As people's demands for lighting effects increase, spotlights, which can provide ambiance and a sense of depth, are being used more and more widely, such as in hotels and shopping malls to illuminate colors, and in countertops to light up merchandise. Spotlights differ from ordinary lights in that they need to be adjusted at different angles to illuminate objects and highlight their effects; therefore, the spotlight angle adjustment mechanism is a crucial component. Existing spotlight angle adjustment mechanisms may require the entire spotlight or part of it to rotate or sway when adjusting the angle, which can easily interfere with external spaces, making them inconvenient to use and cumbersome to install. Utility Model Content

[0003] The purpose of this utility model is to provide a spotlight angle adjustment structure that is simple and compact, easy to install, and does not require rotating the spotlight body when adjusting the angle.

[0004] To achieve the above objectives, this utility model provides a spotlight angle adjustment structure, including a cylindrical outer shell and an LED light and a rotating component disposed inside the outer shell. The bottom of the outer shell is provided with a bottom wall, and a mounting platform is provided with the bottom wall protruding upwards. The LED light is fixedly mounted on the top surface of the mounting platform.

[0005] The rotating assembly covers the upper part of the mounting platform and includes a rotating ring, a lens holder, and a lens. The rotating ring is fixedly snapped into the housing, the lens holder is rotatably fitted into the rotating ring, and the lens is fixedly mounted on the top of the lens holder.

[0006] The lens holder is hollow inside and has an outer wall that is an arc-shaped spherical surface. The inner wall of the lower end of the rotating ring is concave and its shape matches the arc-shaped spherical surface of the outer wall of the lens holder. The outer wall of the lens holder and the inner wall of the lower end of the rotating ring are attached to each other and can be rotatably connected. The lens holder can tilt and rotate in a 360° direction within the rotating ring. The lens rotates with the lens holder, thereby changing the angle between the LED light and the lens.

[0007] Furthermore, when the lens mount is not rotating, the bottom surface of the lens mount is parallel to the bottom surface of the rotating ring and the bottom surface of the outer shell, and the lens mount is located inside the rotating ring. The maximum tilt angle of the lens mount depends on the size of the arc-shaped spherical surface that matches the rotating ring and the lens mount. When the lens mount rotates to the maximum angle, one bottom end of the lens mount tilts downward and protrudes out of the rotating ring, while the other bottom end of the lens mount tilts upward and is locked inside the upper edge of the inner wall of the arc-shaped spherical surface of the rotating ring.

[0008] Furthermore, the bottom end of the rotating ring covers the upper end of the mounting platform, the upper end of the mounting platform extends into the lens holder and is located below the lens, and a clearance portion is formed between the mounting platform and the inner wall of the outer shell around the ring, with the lower end of the rotating ring located within the clearance portion.

[0009] Furthermore, the rotating ring includes a front rotating ring and a rear rotating ring. The inner wall of the lower end of the front rotating ring and the inner wall of the rear rotating ring together form an arc-shaped spherical surface that matches the outer wall of the lens mounting base. The front rotating ring and the rear rotating ring are installed and fitted with the lens mounting base from the front and rear sides, respectively.

[0010] Furthermore, the outer walls of the front rotating ring and the rear rotating ring are connected to each other by several sets of buckles and grooves provided on the outer walls and cooperating with each other.

[0011] Furthermore, the front rotating ring is a frustum-shaped structure with its outer wall tapering downwards. The lower end of the front rotating ring is necked and connects with the rear rotating ring to form a straight cylindrical section. The lens mounting base is fitted onto the inner wall of the straight cylindrical section.

[0012] Furthermore, the LED light is fixedly mounted on the mounting platform using an LED bracket. The mounting platform has a wiring hole that connects to the bottom of the housing, and the power cord is connected to the LED light through the wiring hole inside the mounting platform.

[0013] Furthermore, the top of the lens holder extends vertically upward with a mounting flange for mounting the lens. The mounting flange is provided with positioning grooves at intervals, and the upper edge of the lens is provided with a corresponding positioning protrusion. When the lens is installed in the lens holder, the positioning protrusion is embedded in the positioning groove.

[0014] Furthermore, an anti-glare shield is fixedly installed on the top of the outer shell.

[0015] Furthermore, a step is formed by a circumferential concave groove on the inner wall of the top edge of the outer shell, and the outer edge of the upper end of the rotating ring is supported on the step.

[0016] The above-mentioned spotlight angle adjustment structure has a rotating component fixed in the housing, and the rotation operation occurs in the rotating component. The structure is relatively simple and compact, and it is also relatively convenient to install. It is only necessary to assemble the housing and the various parts of the rotating component.

[0017] In this utility model, the angle adjustment structure of the spotlight is adjusted by the lens fixing seat driving the lens to tilt and rotate in the rotating ring, changing the angle of the light-emitting surface of the lens, thereby realizing the angle adjustment of the light. The rotating component is fixedly installed in the housing. When the lens fixing seat rotates, the spotlight body does not rotate, and it is not easy to interfere with the outside.

[0031] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0032] See Figure 1 , Figure 2 This utility model provides a spotlight angle adjustment structure, including a cylindrical outer shell 1 and an LED lamp 3 and a rotating component 20 disposed inside the outer shell 1. The bottom of the outer shell 1 is provided with a bottom wall 11, and a mounting platform 12 is provided on the bottom wall 11. The annular space defined between the mounting platform 12 and the inner wall of the outer shell 1 forms a clearance part 13. The LED lamp 3 is fixedly mounted on the mounting platform 12 by an LED bracket 31. A wiring hole connected to the bottom of the outer shell 1 is passed through the mounting platform 12. The power cord is connected to the LED lamp 3 through the wiring hole (not shown) in the mounting platform 12.

[0033] The rotating assembly 20 covers the upper end of the mounting platform 12 and includes a rotating ring, a lens holder 23, and a lens 24. The rotating ring is fixedly snapped into the housing 1, the lens holder 23 is rotatably fitted inside the rotating ring, and the lens 24 is fixedly mounted on the top of the lens holder 23.

[0034] The components of the above structure can be manufactured separately and then assembled into a whole. The structure is simple and easy to install. After installation, the rotating component 20 is located inside the outer shell 1, and the entire lamp body structure is relatively compact.

[0035] The lens holder 23 is hollow inside and its outer wall is an arc-shaped spherical surface. The inner wall of the lower end of the rotating ring is concave and its shape matches the arc-shaped spherical surface of the outer wall of the lens holder 23. A circumferential rotating surface S is formed between the outer wall of the lens holder 23 and the inner wall of the lower end of the rotating ring. The outer wall of the lens holder 23 and the inner wall of the lower end of the rotating ring are in contact with each other and can be rotatably connected. When adjusting the spotlight angle, the rotation occurs on the rotating surface S. Since the rotating surface S is circumferential, the lens holder 23 of this invention can tilt and rotate in a 360° direction within the rotating ring. The maximum tilt angle depends on the size of the rotating surface S. In this embodiment, the maximum tilt angle is 25°. Here, the tilt angle refers to the lens holder 23 when it is not rotating and is in a neutral position (e.g., when it is in a neutral position). Figure 5 The central axis of ) and when rotated to the maximum angle (e.g. Figure 6 The angle between the central axis of the lens 24 and the lens 23 is as follows: The lens 24 rotates with the lens mount 23, thereby changing the angle between the LED lamp 3 and the lens 24; and the rotating surface S is a matching arc-shaped spherical structure, so that the lens mount 23 can rotate relatively smoothly.

[0036] Furthermore, the thickness of the lens 24 is relatively small, or the lower end of the lens 24 may also have an upward-facing recess to prevent collision interference between the lens 24 and the LED lamp 3 when the lens holder 23 rotates.

[0037] See Figure 3 , Figure 4 , Figure 7Specifically, for easier installation, the rotating ring in this embodiment can be a split structure, including a front rotating ring 21 and a rear rotating ring 22. The front rotating ring 21 is a frustum-shaped structure with its outer wall tapering downwards. The lower end of the front rotating ring 21 is necked and connects with the rear rotating ring 22 to form a straight cylindrical section. The lens mounting base 23 fits onto the inner wall of the straight cylindrical section. Specifically, the lower inner wall of the front rotating ring 21 and the inner wall of the rear rotating ring 22 (i.e., the inner wall of the straight cylindrical section) together form an arc-shaped spherical surface that fits onto the outer wall of the lens mounting base 23. The front rotating ring 21 and the rear rotating ring 22 are installed and fitted onto the lens mounting base 23 from the front and rear sides, respectively. When assembling the rotating assembly 20, the lens mounting base 23, on which the lens 24 is mounted, can be pushed forward from the rear of the front rotating ring 21 and locked into the front rotating ring 21, so that the rotating surfaces S match. Then, the rear rotating ring 22 is installed from the rear of the lens mounting base 23 and forms a fixed connection with the front rotating ring 21. In this embodiment, the outer wall of the rear end of the front rotating ring 21 is provided with a plurality of buckles 211 protruding rearward, and the outer wall of the front end of the rear rotating ring 22 is provided with a plurality of buckles 211. The outer walls of the front rotating ring 21 and the rear rotating ring 22 are connected to each other by buckles 211 and buckle grooves 221.

[0038] The assembled rotating component 20 can be directly installed into the housing 1 where the LED light 3 is fixed, so that the bottom end of the rear rotating ring 22 covers the upper end of the mounting platform 12, the upper end of the mounting platform 12 extends into the lens fixing seat 23 and is located below the lens 24, and the lower end of the rear rotating ring 22 is located in the clearance part 13.

[0039] See Figure 5 , Figure 6 After assembly according to the above structure, when the lens holder 23 is not rotating, the bottom surface of the lens holder 23 is parallel to the bottom surface of the rotating ring and the bottom surface of the outer casing 1, and the lens holder 23 is located inside the rotating ring. When the lens holder 23 rotates to its maximum angle, one bottom end of the lens holder 23 tilts downward and protrudes outside the rotating ring, while the other bottom end of the lens holder 23 tilts upward and is locked inside the upper edge of the inner wall of the arc-shaped spherical surface of the rotating ring. Thus, the clearance part 13 is designed to prevent interference to the lens holder 23 during rotation, allowing it to tilt freely in a 360° direction. As the lens 24 rotates with the lens holder 23, the angle between the light-incident surface 241 of the lens 24 and the LED lamp 3 changes, and the angle of the light-exit surface 242 of the lens 24 also changes, thereby changing the beam angle of the spotlight. The rotating assembly 20 is fixedly installed inside the outer casing 1. When the lens holder 23 rotates, the spotlight body does not rotate, making it less prone to interference with the outside and allowing for more flexible installation scenarios for spotlights with this angle adjustment structure.

[0040] In this embodiment, the top of the lens holder 23 extends vertically upward with a mounting flange 231 for mounting the lens 24. The mounting flange 231 is provided with positioning grooves 232 at intervals. The upper edge of the lens 24 is provided with a corresponding positioning protrusion 243. When the lens 24 is installed in the lens holder 23, the positioning protrusion 243 is embedded in the positioning groove 232, thereby the lens 24 can be fixed in the lens holder 23 and rotate stably with the lens holder 23.

[0041] In this embodiment, a step 14 is formed by a circumferential concave inward on the inner wall of the top edge of the outer shell 1. The upper outer edge of the front rotating ring 21 is supported on the step 14. An anti-glare cover 4 is also fixedly installed on the top of the outer shell 1. The anti-glare cover 4 covers the entire outer shell 1 and the rotating assembly 20. The light emitted from the light-emitting surface 242 of the lens 24 passes through the anti-glare cover 4, which has an anti-glare effect.

[0042] The above is merely one embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
