Description
Technical Field
[0001] This utility model relates to the field of LED lighting technology, specifically to an adjustable LED light. Background Technology
[0002] LED lights, or light-emitting diode lights, are lighting fixtures that use light-emitting diodes as their core light-emitting element. Their working principle involves the recombination of electrons and holes when a forward voltage is applied across a semiconductor material, converting the released energy into visible light. Unlike traditional incandescent lamps that require heating a filament, LED lights do not rely on gas discharge, resulting in higher luminous efficiency. Compared to traditional lighting fixtures, LED lights have significant advantages: extremely low energy consumption, a lifespan of tens of thousands of hours, and are more environmentally friendly as they do not contain harmful substances such as mercury. They also feature fast start-up and flexible color adjustment, and are now widely used in various scenarios such as home lighting, outdoor lighting, electronic screens, and automotive lighting.
[0003] Existing LED lights typically achieve angle adjustment via a hinge after installation. However, because the light body cannot be effectively locked after adjustment, it can easily shift its angle with slight touches or airflow disturbances. This necessitates frequent manual adjustments to restore normal illumination, increasing the complexity of daily operation, making it inconvenient for users, and reducing the practicality of the LED light. Therefore, we propose an adjustable LED light. Utility Model Content
[0004] The purpose of this utility model is to provide an adjustable LED light to solve the problem mentioned in the background art that existing LED lights are mostly adjusted by a rotating shaft after installation. However, since the light body cannot be effectively locked after adjustment, the angle will shift due to slight touch or airflow disturbance. As a result, users need to frequently manually readjust the angle of the light body to restore normal lighting, which increases the cumbersomeness of daily operation, is inconvenient for users, and reduces the practicality of LED lights.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable LED lamp, including a base, an LED lamp body is provided on one side of the base, a rotating column is fixedly connected to the center of one side of the LED lamp body, a driven bevel gear is fixedly installed near the center of the surface of the rotating column, the lower end of the driven bevel gear is meshed with a driving bevel gear, a rotating rod is provided at the lower end of the center of the base, an annular plate is fixedly connected to the center of the bottom of the base, a knob is provided at the lower end of the annular plate, a groove is provided at the center of the bottom of the rotating rod, a spring is fixedly connected to the top of the groove, a connecting post is fixedly connected to the lower end of the spring, the bottom of the connecting post extends through to the outside of the groove and is fixedly connected to the center of the bottom of the knob, limit pins are fixedly connected to the top of the knob near both sides, a limit groove is provided at the bottom of the annular plate, sliding grooves are provided near the bottom of both sides of the groove, and sliders are fixedly connected to the top of both sides of the connecting post.
[0006] Compared with the prior art, the beneficial effects of this utility model are: This adjustable LED light effectively solves the technical problem of easy displacement after angle adjustment in existing LED lights through the design of a rotating column, driven bevel gear, rotating rod, driving bevel gear, knob, groove, connecting column, spring, annular plate, slide groove, slider, limiting groove, and limiting pin. Specifically, the sliding cooperation between the slider and the slide groove guides the vertical movement of the connecting column, ensuring that the connecting column is pulled vertically along the groove only, preventing the limiting pin from misaligning with the limiting groove due to the connecting column's displacement. Furthermore, when the knob is rotated, the slider can closely engage with the side wall of the slide groove to transmit torque, driving the rotating rod to rotate synchronously, thus achieving the desired connection between the knob, connecting column, and... The continuous transmission of the rotating rod eliminates slippage or lag, ensuring smooth and stable adjustment of the LED light's angle. Simultaneously, the spring's elastic reset function, combined with the mechanical limiting structure of the limiting pin and groove, allows for angle adjustment by pulling the knob, disengaging the limiting pin from the groove. Releasing the knob pushes the connecting column upwards, re-engaging the limiting pin into the groove for rigid locking. Compared to existing rotating shafts that rely on damping friction, this provides more stable locking force, effectively resisting minor touches and airflow disturbances, preventing the light's angle from shifting on its own, eliminating the need for frequent readjustments, and adapting to different lighting scenarios, significantly improving the product's practicality and reliability.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Please see Figure 1-5 This utility model provides a technical solution: an adjustable LED lamp, including a base 1, an LED lamp body 2 on one side of the base 1, a rotating column 3 fixedly connected to the center of one side of the LED lamp body 2, a driven bevel gear 4 fixedly installed near the center of the surface of the rotating column 3, a driving bevel gear 6 meshing with the lower end of the driven bevel gear 4, a rotating rod 5 at the lower end of the center inside the base 1, an annular plate 12 fixedly connected to the center of the bottom of the base 1, a knob 8 at the lower end of the annular plate 12, a groove 9 at the center of the bottom of the rotating rod 5, a spring 11 fixedly connected to the top of the groove 9, a connecting column 10 fixedly connected to the lower end of the spring 11, the bottom of the connecting column 10 extending through to the outside of the groove 9 and fixedly connected to the center of the bottom of the knob 8, limit pins 16 fixedly connected to the top of the knob 8 near both sides, a limit groove 15 opened at the bottom of the annular plate 12, sliding grooves 13 opened near the bottom of both sides of the groove 9, and sliders 14 fixedly connected to the top of both sides of the connecting column 10.
[0011] One end of the rotating column 3 extends into the interior of the base 1 and is movably connected to the No. 1 bearing, which is fixedly installed on one side of the base 1 near the top, to provide rotational support for the rotating column 3.
[0012] A support frame 7 is fixedly connected to the center of the seat 1. A second bearing is fixedly installed at the center of the inner wall of the support frame 7. The upper end of the rotating rod 5 passes through the outside of the second bearing and is fixedly connected to the center of the bottom of the driving bevel gear 6. The inner ring of the second bearing is fixedly connected to the outer wall of the rotating rod 5. The lower end of the rotating rod 5 passes through the outside of the seat 1 and the annular plate 12 in sequence, ensuring the stability of the rotating rod 5 when rotating.
[0013] The number of limiting slots 15 is twenty-four. The bottom of the two limiting pins 16 penetrates into the interior of the two limiting slots 15 and contacts the inner wall of the limiting slots 15. The twenty-four evenly distributed limiting slots 15, together with the two limiting pins 16, can realize the fine adjustment of the two angles of the LED lamp body. The angle interval between adjacent limiting slots 15 is fifteen degrees, which can adapt to the lighting angle requirements of different scenarios such as office, reading, and display. At the same time, the two limiting pins 16 are simultaneously engaged in the limiting slots 15, which can form bidirectional limiting, improve the stability of angle locking, avoid the locking failure caused by uneven force on a single limiting pin 16, and ensure that the lamp body angle can resist external forces such as slight touch and airflow disturbance after locking, preventing the angle from shifting on its own.
[0014] The opposing sides of the two sliders 14 extend into the interior of the two slide grooves 13 and slide in connection with the inner wall of the slide grooves 13. The sliding engagement of the sliders 14 and the slide grooves 13 provides precise guidance for the movement direction of the connecting post 10, ensuring that the connecting post 10 can only move up and down along the axis of the groove 9. This avoids misalignment between the limiting pin 16 and the limiting groove 15 due to the offset of the connecting post 10, ensuring the precise engagement of the locking structure. On the other hand, when the knob 8 is rotated, the sliders 14 are in close contact with the side wall of the slide groove 13, which can transmit the rotational torque of the knob 8 to the rotating rod 5, achieving synchronous rotation of the knob 8, the connecting post 10 and the rotating rod 5. This avoids relative slippage among the three and ensures that the torque for angle adjustment can be stably transmitted.
[0015] The outer wall of knob 8 is provided with anti-slip diagonal grooves to prevent the user from slipping when pulling or turning knob 8.
[0016] A mounting plate is fixedly connected to the other side of the base 1. Several mounting holes are opened on one side of the mounting plate. Users can fix the base 1 to different mounting surfaces such as walls, ceilings, and cabinets by passing bolts, expansion screws and other connecting parts through the mounting holes.
[0017] Working principle: When adjusting the angle of the LED light body 2, the user first holds the knob 8 with anti-slip diagonal texture on the outer wall and pulls it downwards. During the pulling process, the knob 8 drives the bottom fixed connecting post 10 to move downwards along the axis of the groove 9 at the bottom of the rotating rod 5. At this time, the top of the connecting post 10 stretches the spring 11, and at the same time, the sliders 14 on both sides of the connecting post 10 slide vertically down along the groove 13 on the inner wall of the groove 9. As the connecting post 10 moves downwards, the two limit pins 16 at the top of the knob 8 gradually disengage from the annular plate. The bottom limiting groove 15 of 12 releases the angle lock on the rotating rod 5. Then, while keeping the knob 8 pulled, ensure that the limiting pin 16 is completely disengaged from the limiting groove 15. The user rotates the knob 8 clockwise or counterclockwise. Because the slider 14 is tightly fitted with the side wall of the slide groove 13, the rotational torque of the knob 8 is transmitted to the slider 14 through the connecting column 10. The slider 14 then drives the rotating rod 5 to rotate synchronously. The driving bevel gear 6 fixed at the upper end of the rotating rod 5 rotates with the rotating rod 5, thereby driving the driven bevel gear 6 meshing with it. The moving bevel gear 4 rotates, and the driven bevel gear 4 is fixed on the surface of the rotating column 3. Therefore, the rotating column 3 rotates synchronously under the rotational support of the first bearing, which ultimately drives the LED lamp body 2, which is fixedly connected to the rotating column 3, to achieve angular deflection. Since there are twenty-four evenly distributed limiting grooves 15 on the annular plate 12, the LED lamp body 2 can be precisely controlled to adjust its angle at 15-degree intervals by rotating the knob 8 during the adjustment process, adapting to different lighting scene requirements. When the LED lamp body 2 is adjusted to the target angle, the user releases the pressure on the knob 8. At this time, the compressed spring 11 in the groove 9 releases its elastic potential energy, pushing the connecting column 10 to reset upward along the slide groove 13. The connecting column 10 drives the knob 8 to move upward synchronously until the two limiting pins 16 at the top of the knob 8 are re-engaged into the corresponding limiting grooves 15 at the bottom of the annular plate 12, forming a mechanical lock again. This locking structure can resist external forces such as slight touch and airflow disturbance, preventing the LED lamp body 2 from shifting its angle on its own, thus completing the entire angle adjustment process.
[0018] In summary, this adjustable LED light, through the design of the rotating column 3, driven bevel gear 4, rotating rod 5, driving bevel gear 6, knob 8, groove 9, connecting column 10, spring 11, annular plate 12, sliding groove 13, slider 14, limiting groove 15, and limiting pin 16, effectively solves the technical pain point of easy displacement after the angle adjustment of existing LED lights. Specifically, the sliding cooperation between slider 14 and sliding groove 13 guides the up-and-down movement of connecting column 10, ensuring that connecting column 10 is only pulled vertically along groove 9, preventing the limiting pin 16 from failing to accurately align with limiting groove 15 due to displacement of connecting column 10. Furthermore, when knob 8 is rotated, slider 14 can tightly fit against the side wall of sliding groove 13 to transmit torque, driving rotating rod 5 to rotate synchronously. The rotation of the knob 8, connecting column 10, and rotating rod 5 ensures smooth and stable angle adjustment of the LED lamp body 2 without slippage or lag. Simultaneously, the elastic reset function of the spring 11, combined with the mechanical limiting structure of the limiting pin 16 and limiting groove 15, allows the limiting pin 16 to disengage from the limiting groove 15 for angle adjustment when the knob 8 is pulled. Upon release, the spring 11 pushes the connecting column 10 upwards, causing the limiting pin 16 to re-engage into the limiting groove 15, forming a rigid lock. Compared to existing rotating shafts that rely on damping friction, this provides a more stable locking force, effectively resisting external forces such as slight touches and airflow disturbances, preventing the lamp body angle from shifting on its own, eliminating the need for frequent readjustments, adapting to different lighting scenarios, and significantly improving the product's practicality and reliability.
