Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a dual-axis, multi-dimensional, precise adjustment, light-leakage-proof ceiling lighting device. Background Technology

[0002] Currently, end users often need to adjust multiple ceiling lights to different illumination angles to achieve focused or diffused light effects. However, existing lighting fixtures on the market have the following drawbacks:

[0003] The angle cannot be adjusted or can only be adjusted on a single plane;

[0004] The adjustment process is complex and requires the assistance of tools or professional personnel.

[0005] Light leakage can easily occur during adjustment, affecting luminous efficiency. Therefore, how to achieve multi-dimensional and convenient adjustment of ceiling lights while preventing light leakage has become a pressing technical problem to be solved in this field. Utility Model Content

[0006] This utility model provides a dual-axis, multi-dimensional, precise adjustment ceiling lighting device to prevent light leakage. It achieves dual-axis adjustment of horizontal plane rotation and vertical plane swing through an innovative mechanical structure, while optimizing the light leakage prevention design to improve user operation convenience and light efficiency stability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A dual-axis, multi-dimensional, precision-adjustable, light-leakage-proof ceiling lighting device includes an outer frame, a central ring, a heat sink, and a light shield.

[0009] The middle ring is rotatably installed inside the outer frame, and a limiting structure is provided between the middle ring and the outer frame to limit the number of rotations;

[0010] The radiator is connected to the central ring via a swingable connection structure and can swing relative to the central ring in the vertical plane.

[0011] The bottom of the outer frame can selectively abut against the radiator's angle positioning structure to switch between different irradiation angles;

[0012] The radiator, light shield, and central ring form a light-proof system through a light-blocking combination structure.

[0013] Furthermore, the limiting structure includes a middle ring positioning post disposed on the outer wall of the middle ring and an outer frame positioning post disposed on the inner wall of the outer frame, which limit the number of rotations of the middle ring by abutting against each other.

[0014] Furthermore, the top of the radiator has a mounting portion, and the swingable connection structure includes a central ring boss that protrudes inward from the inner wall of the central ring, a central ring fixing groove that is recessed inward from the central ring boss, and a fixing post that protrudes outward from the outside of the mounting portion of the radiator. The central ring fixing groove is fitted into the fixing post from top to bottom to form a connection, wherein the upper surfaces of the fixing groove and the fixing post are both arc-shaped structures, allowing the radiator to swing left and right relative to the central ring.

[0015] Furthermore, the angle positioning structure includes an inclined step and a horizontal step set on the upper part of the radiator. When the radiator swings left and right, the bottom of the outer frame switches between inclined illumination and forward light emission states by abutting different steps of the radiator.

[0016] Furthermore, the light-shielding structure includes:

[0017] When the lamp is laid flat or tilted, the inner wall of the mounting part of the heat sink blocks light from one side.

[0018] When the lamp is laid flat, the upper surface of the mounting part of the heat sink is flush with the lower end of the light shield to block light from leaking out from the left side; when the lamp is tilted, the upper surface of the mounting part abuts against the light shield to limit light leakage.

[0019] The inner wall of the central ring serves to block the light leakage path between the light shield and the heat sink when the lamp is laid flat or tilted.

[0020] Furthermore, the middle ring is connected to the outer frame via a hook-up structure, the hook-up structure comprising:

[0021] A central ring step is set at the top periphery of the central ring, and an outer frame boss is set on the inner wall of the outer frame. During installation, the central ring step is hooked onto the upper surface of the outer frame boss, and the upper surface of the outer frame boss abuts against the lower surface of the central ring step.

[0022] The middle ring is symmetrically provided with middle ring pressure tongues on both sides, and a small platform is provided on the middle ring pressure tongue. The lower surface of the outer frame boss abuts against the upper surface of the small platform to realize the elastic snap-fit ​​fixation between the middle ring and the outer frame.

[0023] During disassembly, the small platform is separated from the lower surface of the outer frame boss by squeezing the middle ring tongue inward, thus achieving rapid disassembly of the middle ring and the outer frame.

[0024] Furthermore, the middle ring is locked to the radiator by screws. The screws pass through the screw holes of the middle ring and the screw holes of the radiator to form a locking connection. The screw holes of the radiator are located on the fixing post, and the screw holes of the middle ring are located in the fixing groove of the middle ring.

[0025] Furthermore, the outer frame is equipped with spring fixing columns for installing ceiling springs.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] This invention proposes a dual-axis, multi-dimensional, precise adjustable light-leakage-proof ceiling lighting device, comprising an outer frame, a central ring, a radiator, and a light shield. The central ring is rotatably mounted on the outer frame, with the number of rotations limited by positioning posts. The radiator achieves vertical swing via an arc-shaped hanging structure, and the bottom of the outer frame abuts against the radiator's step to switch the illumination angle. The light-leakage-proof structure is formed by the radiator mounting part, the light shield, and the inner wall of the central ring. The central ring and the outer frame are elastically connected by a pressure tongue, and the outer frame has pre-drilled through holes for easy maintenance. Beneficial effects: It achieves dual-axis adjustment of horizontal rotation and vertical swing, meeting the angle requirements of various scenarios; the purely mechanical structure design allows for manual adjustment, making it convenient and efficient; the multi-component collaborative light shielding improves light utilization efficiency; the positioning posts and step abutment enhance structural stability and extend service life.

[0039] like Figure 1-6 As shown, a dual-axis, multi-dimensional, precise adjustable light-leakage-proof ceiling lighting device includes an outer frame 3, a central ring 2, a radiator 5, and a light shield 1. Its core structure is as follows:

[0040] Dual-axis adjustment system

[0041] 360° horizontal rotation: The middle ring 2 is hooked onto the upper surface of the outer frame boss 31 of the outer frame 3 via the middle ring step 21, and is fixed by the elastic snap-fit ​​of the middle ring pressure tongue 22. The middle ring positioning post 23 abuts against the outer frame positioning post 32, limiting the number of rotations of the middle ring and preventing excessive rotation.

[0042] Vertical plane left and right swing: The middle ring 2 is connected to the fixing post 52 of the heat sink 5 through the middle ring boss 25 and the middle ring fixing groove 26. The two are oscillating through the arc surface cooperation, and are locked by screw 4 passing through the middle ring screw hole 24 and the heat sink screw hole 51.

[0043] Angle switching and positioning: The bottom 34 of the outer frame 3 can selectively abut against the inclined step 55 or the horizontal step 56 of the heat sink 5 to achieve inclined illumination or forward light emission respectively, without the need for additional locking devices.

[0044] Light-proof structure

[0045] Right-side light shielding: The inner wall of the radiator mounting section 54 blocks light from the right side;

[0046] Left side light shield: When the radiator mounting part 54 is laid flat, the upper surface is flush with the lower end of the light shield 1, and when tilted, it abuts against the light shield to block light from leaking out from the left side;

[0047] Central ring auxiliary shading: The inner wall of the central ring 27 blocks the light leakage path between the shading cover and the heat sink, and works with the spring fixing column 33 to reduce light reflection and leakage.

[0048] Specifically, the principle behind preventing light leakage is as follows:

[0049] In the flat position: the light on the right is blocked by the inner wall of the radiator mounting part 54, and the light on the left cannot leak out because the upper surface of the radiator mounting part is flush with the light shield. The inner wall of the middle ring 27 blocks the light leakage path between the light shield and the radiator.

[0050] Tilted position: The light on the right is blocked by the inner wall of the radiator mounting part and the inner wall of the middle ring, and the upper surface of the radiator mounting part on the left abuts against the light shield, forming a fully enclosed light shielding path.

[0051] Easy installation and maintenance

[0052] The middle ring and the outer frame are elastically connected by a pressure tongue. Disassembly is only required by squeezing the pressure tongue inward, without the need for tools.

[0053] The outer frame has a pre-drilled through hole. After aligning it with the 24mm central ring screw hole, it can be directly operated with a screwdriver, simplifying the maintenance process.

[0054] Specifically, the angle adjustment process of this utility model is as follows:

[0055] Horizontal plane angle adjustment: Rotate the middle ring 2 by hand. The number of rotations is determined by the feedback of the contact between the middle ring positioning column 23 and the outer frame positioning column 32, so as to achieve horizontal plane direction adjustment.

[0056] Vertical angle adjustment: Swing the radiator 5, and adjust the bottom 34 of the outer frame to abut the radiator with the inclined step 55 (inclined illumination) or the horizontal step 56 (forward light emission) as needed, and lock the angle by abutting the step.

[0057] This utility model provides a ceiling light fixture that achieves multi-dimensional adjustment and efficient light leakage prevention through an innovative mechanical structure. It consists of an outer frame, a central ring, a heat sink, and a light shield. The central ring is rotatably installed within the outer frame, and its rotation is limited by a positioning post on the central ring that abuts against a positioning post on the outer frame. The heat sink is connected to a fixing post on the heat sink via a groove with an arc-shaped surface on the central ring, allowing for vertical swing. The bottom of the outer frame can selectively abut against an inclined or horizontal step on the heat sink to switch the illumination angle. The heat sink, light shield, and inner wall of the central ring work together to form a light leakage prevention system. The central ring and outer frame are elastically connected by a pressure tongue for easy assembly and disassembly. Pre-drilled through holes on the outer frame facilitate maintenance. This utility model achieves dual-axis adjustment of horizontal rotation and vertical swing, allowing for omnidirectional illumination angles to meet different scenario needs. Its purely mechanical design allows for easy manual angle adjustment. Multiple components work together to shield light, effectively reducing light leakage and improving light efficiency. The positioning post limit and step abutment design enhance structural stability and extend the lifespan of the light fixture.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
