Description

Technical Field

[0001] The present invention relates to the technical field of LED ceiling lamps, and in particular to an LED ceiling lamp. Background Art

[0002] An LED lamp is a light-emitting diode, a commonly used light-emitting device that emits light through the release of energy from the recombination of electrons and holes. It has the advantages of high energy efficiency, long life, and environmental protection, and is therefore widely used in the lighting field. When used for home lighting, LED lamps are also used in ceiling lamps. Currently, there are two main ways to assemble ceiling lamps. The first method is to insert the ceiling lamp from the top of the suspended ceiling; the second method is to lock the ceiling lamp with screws from the bottom of the suspended ceiling. Ceiling lamps installed with the first method require maintenance from above the suspended ceiling, which is quite inconvenient. Ceiling lamps installed with the second method require dust filling from below the suspended ceiling after installation, which is a more cumbersome operation. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the background technology.

[0004] The present invention provides an LED ceiling lamp, comprising:

[0005] A lamp holder, wherein a first through hole is provided on the bottom surface of the lamp holder, a first guide cylinder is provided on the top surface of the lamp holder, the first guide cylinder extends vertically, and a support pad is also provided on the top surface of the lamp holder;

[0006] a lifting spring seat, the lifting spring seat sliding along the first guide cylinder, the lifting spring seat including a horizontal column located at the top, a first screw hole being provided on the bottom surface of the lifting spring seat, the first screw hole being connected to the first through hole;

[0007] a torsion spring, the torsion spring being sleeved on the horizontal post, the torsion spring comprising a first end and a second end, the first end and the second end both being inclined downward, the first end abutting against the support block, and the second end abutting against the lamp holder;

[0008] an adjusting screw passing through the first through hole and being threadedly connected to the first screw hole;

[0009] A lamp body is arranged on the lamp holder.

[0010] The beneficial effects of the present invention are as follows: the LED ceiling lamp is configured with a lifting spring seat, a torsion spring and an adjusting screw, so that the LED ceiling lamp can be conveniently installed and disassembled from the lower side of the suspended ceiling, and can be clamped with the suspended ceiling by the torsion spring in the installed state, and the LED ceiling lamp is firmly installed and has good shock resistance.

[0011] The LED ceiling lamp of the present invention can be installed from below the suspended ceiling. During installation, the torsion spring abuts the inner wall of the lamp hole in the suspended ceiling, and the second end of the torsion spring swings inward against the elastic force. During installation, an adjustment screw is simply screwed into the first screw hole pre-set on the lamp holder. The adjustment screw pulls the lifting spring holder toward the side where the lamp holder is located, causing the first and second ends of the torsion spring to compress the lamp holder, pressing the lamp holder tightly against the suspended ceiling through the torsion spring. LED ceiling lamps installed in this manner are easy to install and do not require re-dusting of the suspended ceiling after installation, eliminating subsequent repair processes and reducing costs.

[0012] As some sub-solutions of the above technical solution, the first through hole is a countersunk hole, and the LED ceiling lamp further includes a sealing plug, which is arranged in the first through hole and tightly plugs the first through hole.

[0013] As some sub-solutions of the above technical solution, the LED ceiling lamp further includes a spring, which is located in the first guide tube, with the upper end of the spring abutting against the lifting spring seat and the lower end of the spring abutting against the lamp holder.

[0014] As some sub-solutions of the above technical solution, a wire hole is also provided on the top surface of the lamp holder, the lower end of the wire hole is connected to the first through hole, and a connecting rope is fixed to the second end, and the connecting rope passes downward through the wire hole and is connected to the sealing plug.

[0015] As some sub-solutions of the above technical solution, the connecting rope is a steel wire rope.

[0016] As some sub-solutions of the above technical solution, one end of the steel wire rope is welded to the second end of the torsion spring.

[0017] As some sub-solutions of the above technical solution, the second end of the torsion spring is bent upward, and one end of the steel wire rope is connected to the second end by a knot.

[0035] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0036] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0037] In the description of the present invention, "several" means an indefinite quantity, "multiple" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, and "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" is solely for the purpose of distinguishing technical features and should not be understood to indicate or imply relative importance, or to implicitly indicate the number or order of the technical features indicated. "And / or" throughout the text represents three parallel solutions. For example, "A and / or B" means a solution where A satisfies, a solution where B satisfies, or a solution where both A and B satisfy.

[0038] In the description of the present invention, if there is a short sentence containing multiple parallel features, the attributive defines the closest feature. For example, "B, C, and E are arranged on A, and E is connected to D" means that B is arranged on A and E is connected to D, and does not constitute a limitation on C. However, attributives that express the relationship between features, such as "spaced arrangement" and "circular arrangement", do not fall into this category. If the word "all" is preceded by an attributive, it means that all features in the short sentence are limited. For example, "B, C, and D are all arranged on A" means that B, C, and D are all arranged on A. In a sentence with an omitted subject, the omitted subject is the subject of the previous sentence, that is, "B is arranged on A, including C" means that B is arranged on A and A includes C.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] The following combination Figures 1 to 5 Embodiments of the present invention are described.

[0041] This embodiment relates to an LED ceiling lamp, including:

[0042] Lamp holder 1, lifting spring seat 2, torsion spring 3, adjusting screw 4, lamp body 5,

[0043] The bottom surface of the lamp holder 1 is provided with a first through hole 11, the top surface of the lamp holder 1 is provided with a first guide tube 12, the first guide tube 12 extends vertically, and the top surface of the lamp holder 1 is also provided with a support pad;

[0044] The lifting spring seat 2 slides along the first guide cylinder 12. The lifting spring seat 2 includes a horizontal column 22 located at the top. The bottom surface of the lifting spring seat 2 is provided with a first screw hole, and the first screw hole is connected to the first through hole 11.

[0045] The torsion spring 3 is sleeved on the horizontal column 22. The torsion spring 3 includes a first end 31 and a second end 32. The first end 31 and the second end 32 are both tilted downward. The first end 31 abuts against the support block, and the second end 32 abuts against the lamp holder 1.

[0046] The adjusting screw 4 passes through the first through hole 11 and is threadedly connected to the first screw hole;

[0047] The lamp body 5 is arranged on the lamp holder 1 .

[0048] The LED ceiling lamp is configured with a lifting spring seat 2, a torsion spring 3 and an adjusting screw 4, so that the LED ceiling lamp can be easily installed and disassembled from the lower side of the suspended ceiling 9, and can be clamped with the suspended ceiling 9 by the torsion spring 3 in the installed state. The LED ceiling lamp is firmly installed and has good shock resistance.

[0049] The installation method of the LED ceiling lamp includes the following steps:

[0050] S1: Prepare the suspended ceiling 9, which has light holes pre-opened;

[0051] S2: Install the suspended ceiling 9 on the ceiling;

[0052] S3: Push the lamp holder 1 into the lamp hole from below until the lamp holder 1 abuts against the bottom surface of the suspended ceiling 9. At this time, the second end 32 of the torsion spring 3 abuts against the top surface of the suspended ceiling 9 under the action of the elastic force.

[0053] S4: Screw in the adjusting screw 4 to lower the lifting spring seat 2 so that the second end 32 presses tightly against the suspended ceiling 9.

[0054] The LED ceiling lamp of the present invention can be installed from below the suspended ceiling 9. During installation, the torsion spring 3 abuts against the inner wall of the lamp hole on the suspended ceiling 9, and the second end 32 of the torsion spring 3 swings inward against the elastic force. Moreover, during installation, it is only necessary to screw the adjusting screw 4 into the first screw hole preset on the lamp holder 1. The adjusting screw 4 can pull the lifting spring seat 2 toward the side where the lamp holder 1 is located, so that the first end 31 and the second end 32 of the torsion spring 3 compress the lamp holder 1, and the lamp holder 1 is pressed tightly against the suspended ceiling 9 through the torsion spring 3. The LED ceiling lamp installed in this way is easy to install, and there is no need to re-dust the suspended ceiling 9 after installation, which saves the subsequent repair process and is low in cost.

[0055] The first through hole 11 is a countersunk hole, and the LED ceiling lamp further includes a sealing plug 7, which is disposed within the first through hole 11 and tightly plugs the first through hole 11. The first through hole 11 is a countersunk hole, so that after the first screw is inserted into the first through hole 11, the sealing plug 7 can be inserted into the bottom opening of the first through hole 11, covering the adjustment screw 4 at the first through hole 11. This not only protects the adjustment screw 4 from corrosion, but also conceals the adjustment screw 4, making the LED ceiling lamp more aesthetically pleasing after installation.

[0056] The LED ceiling lamp also includes a spring 6, which is located within the first guide tube 12. The upper end of the spring 6 abuts the lift spring seat 2, and the lower end of the spring 6 abuts the lamp holder 1. After the spring 6 is disposed between the lamp holder 1 and the lift spring seat 2, the lift spring seat 2 is maintained at a higher position under the force of the spring 6. Therefore, when no external force is applied, the torsion spring 3 remains at a higher position and can be pushed into the lamp holder 1. The second end 32 of the torsion spring 3 is more easily compressed by the suspended ceiling 9 and passes over the suspended ceiling 9. After the torsion spring 3 passes over the suspended ceiling 9, the second end 32 of the torsion spring 3 pops outward due to its own elastic force, allowing the second end 32 of the torsion spring 3 to rotate above the suspended ceiling 9. Furthermore, the elastic force generated by the spring 6 on the lifting spring seat 2 is configured to overcome the gravity of the lifting spring seat 2 and the adjusting screw 4. In this way, when the adjusting screw 4 is connected to the lifting spring seat 2, the lifting spring seat 2 can still be maintained at a higher position, so that the lifting spring seat 2 can still be pushed into the suspended ceiling 9 by pushing the lifting spring seat 2 upward.

[0057] When the lamp holder 1 is assembled with the suspended ceiling 9, the first end 31 and the second end 32 of the torsion spring 3 abut against the base and the suspended ceiling 9, respectively. If the lamp holder 1 needs to be removed for maintenance, the torsion spring 3 cannot be used to remove the lamp holder 1 from the upper end due to the obstruction of the torsion spring 3. Therefore, a wire hole 13 is provided on the top surface of the lamp holder 1. The lower end of the wire hole 13 communicates with the first through-hole 11. A connecting rope 8 is fixed to the second end 32. The connecting rope 8 passes downward through the wire hole 13 and is connected to the sealing plug 7. When the lamp holder 1 is assembled with the suspended ceiling 9, the connecting rope 8 is pulled through the sealing plug 7, causing the connecting rope 8 to pull the second end 32 of the torsion spring 3 to slide along the top surface of the suspended ceiling 9, causing the second end 32 of the torsion spring 3 to slide down along the top surface of the suspended ceiling 9. At this point, the lamp holder 1 can be removed from the suspended ceiling 9 without having to manipulate the torsion spring 3 from above the suspended ceiling 9. This makes removal more convenient when the lamp body 5 needs to be inspected.

[0058] The connecting rope 8 is a steel wire rope. The steel wire rope has the characteristics of higher structural strength and stronger durability. The connecting rope 8 is also not damaged by the steel wire rope pulling torsion spring 3, and has a longer service life.

[0059] One end of the steel wire rope is welded to the second end 32 of the torsion spring 3. When the steel wire rope is used as the connecting rope 8, the steel wire rope is fixed to the torsion spring 3 by welding, and the connection of the steel wire rope is convenient.

[0060] In addition to being secured to the second end 32 of the torsion spring 3 by welding, in another embodiment, the second end 32 of the torsion spring 3 is bent upward, and one end of the steel wire rope is connected to the second end 32 by a knot. After the second end 32 of the torsion spring 3 is bent upward and the steel wire rope is tied to the second end 32 of the torsion spring 3, the steel wire rope is unlikely to become loose from the second end 32 of the torsion spring 3, ensuring long-term and stable use of the torsion spring 3. This method of connecting the steel wire rope to the second end 32 of the torsion spring 3 offers the advantages of convenient and removable connection.

[0061] When a steel wire rope is used as the connecting rope 8, the end of the steel wire rope can be connected to the sealing plug 7 by directly inserting it into the sealing plug 7. However, this connection method is prone to the end of the steel wire rope being exposed, posing a potential risk of injury. To this end, in another embodiment, the sealing plug 7 is made of a soft material, a second through hole is provided in the middle of the sealing plug 7, a receiving groove is provided in the sealing plug 7, the second through hole is connected to the receiving groove, the lower end of the connecting rope 8 passes through the second through hole, is bent laterally and received in the receiving groove, and the end of the bent portion is inserted into the side wall of the receiving groove. The connecting rope 8 and the sealing plug 7 are connected as one body by the connecting rope 8 passing through the second through hole and the laterally bent portion, and the end of the connecting rope 8 is inserted into the side wall of the receiving groove, which can prevent the end of the steel wire rope from being pricked. In addition, it can ensure that the steel wire rope can still be stably integrated with the sealing plug 7. In this embodiment, the connecting rope 8 can be formed by integral injection molding, and after molding, the connecting rope 8 can be embedded in the interior of the sealing plug 7 in a bent posture. The integral injection molding method has the advantages of low cost and simple structure molding.

[0062] The sealing plug 7 includes an upwardly protruding grip portion 71 and a plug portion 72 connected to the lower side of the grip portion 71. The second through hole passes through the grip portion 71 and the plug portion 72. A grip groove 73 is provided at the connection between the grip portion 71 and the plug portion 72. The provision of the grip groove 73 allows pressure to be applied to the sealing plug 7 when the connecting rope 8 is pulled using the sealing plug 7. By clamping the vertical portion of the steel wire rope and pulling the torsion spring 3, the end of the steel wire rope is less likely to generate shear force on the sealing plug 7, and the steel wire rope is less likely to damage the sealing plug 7.

[0063] The first guide cylinder 12 is provided with an inwardly protruding stopper 121, and the outer wall of the lift spring seat 2 is provided with a stopper groove 21. The stopper 121 extends into and slides within the stopper groove 21. The stopper 121 and the stopper groove 21 prevent the lift spring seat 2 from falling out of the first guide cylinder 12.

[0064] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
