Description

Technical Field

[0001] This invention belongs to the field of LED lighting technology, specifically an LED ceiling light. Background Technology

[0002] LED lights are popular among home users due to their high luminous efficiency, low power consumption, long lifespan, easy control, and safety and environmental friendliness. LED lights come in a variety of styles, and ceiling lights are named for their relatively flat top, which makes them look like they are glued to the ceiling. LED ceiling lights are very popular in the home decoration field.

[0003] Existing LED ceiling lights mainly consist of a lamp body, a lampshade, and a lamp holder. The lamp body is connected and fixed to the ceiling via the lamp holder. The lampshade protects the lamp body and can be made in different styles to enhance its aesthetics. Common ceiling lights in daily life are round, square, or derived from these shapes. However, in actual use, the lampshade completely covers the lamp body, and the good sealing performance of some lampshades prevents the heat emitted by the components when the lamp is emitting light from being dissipated in time. High temperatures accelerate the aging of the lamp body, thus shortening its lifespan.

[0004] To address the issue of lamp covers obstructing heat dissipation and accelerating lamp aging, thus shortening lifespan, existing technologies typically involve creating heat dissipation holes in the lamp cover to allow the heat emitted by the lamp to dissipate effectively. However, dust easily accumulates at these holes, affecting their heat dissipation efficiency. Furthermore, dust from the holes can easily enter the lamp cover and adhere to the lamp, impacting its brightness. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To overcome the aforementioned deficiencies of the prior art, the present invention provides an LED ceiling light that solves the problem that the lampshade covering the lamp body affects its heat dissipation, thereby accelerating the aging of the lamp body and shortening its service life. The prior art generally adopts the method of opening heat dissipation holes on the lampshade to allow the heat emitted by the lamp body to be fully dissipated. However, dust easily accumulates at the heat dissipation holes, thus affecting the heat dissipation effect of the heat dissipation holes. Moreover, the dust in the heat dissipation holes can easily enter the lampshade and adhere to the lamp body, affecting the brightness of the lamp body.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This LED ceiling light features a heat dissipation and cleaning protection device. The heat dissipation holes allow for timely heat dissipation from the lamp body within the lampshade. The protective frame and lampshade cover protect the lamp body. The first and second straight brushes on the cleaning structure effectively remove dust adhering to the lamp body, while the hook brush cleans the heat dissipation holes. This effectively prevents dust from affecting the lamp body's heat dissipation. The cleaned dust falls between the lampshade cover and the protective frame and the lampshade body. Removing the protective frame and lampshade cover allows for cleaning of the dust. The protective frame prevents dust from splashing onto the ground during cleaning.

[0022] 2. This LED ceiling light features a dimming device. In certain usage scenarios, such as taking photos or reading, the light needs to be appropriately blocked to focus or deflect it, thus achieving dimming. The second annular groove and dovetail slide rod allow adjustment of the dimming plate's position, making both plates adjustable. The threaded clamp allows the rubber adhesive block to adhere to the outer surface of the second annular block, fixing the dimming plate's position. The rectangular clamp and frame allow the dimming plate to be detached, enabling users who dislike the dimming plate's impact on the overall aesthetics of the light fixture to remove it.

[0023] 3. This LED ceiling light features an anti-loosening hole installation and removal device. During routine installation, after multiple replacements of the lamp holder, the diameter of the pre-drilled hole in the ceiling may increase, making it difficult for subsequent lamp holders to be securely installed. In this case, the dovetail slider can slide along the inner wall of the sliding groove, allowing it to move to a position away from the pre-drilled hole. Reinstalling the screws and drilling again eliminates the problem of insecure installation caused by the enlarged pre-drilled hole. Furthermore, the four dovetail sliders can be adjusted independently to address different issues with insecure installation around the pre-drilled hole, expanding the screw installation range beyond the limitations of fixed pre-drilled hole positions.

[0041] The working principle of this invention is as follows:

[0042] S1. When cleaning the heat dissipation hole 41 is required, separate the screw hole cover 473 from the threaded hollow block 472. Then, start the drive motor 471, which will drive the rotating rod 474 to rotate, thereby driving the second rectangular block 475 and the third rectangular block 477 to rotate. The rotation of the second rectangular block 475 will drive the first straight brush 476 to rotate, thereby cleaning the bottom of the lamp body 1. The rotation of the third rectangular block 477 will drive the second straight brush 478 and the hook brush 479 to rotate, thereby cleaning the curved surface of the lamp body 1. Clean the heat dissipation holes 41. Dust on the inner wall of the heat dissipation holes 41, the bottom of the lamp body 1, and the arc surface of the lamp body 1 will fall onto the lamp cover 7. Dust on the outside of the heat dissipation holes 41 will fall between the protective outer frame 42 and the lamp cover 3. At this time, pull the first locking rod 44 upward to separate the first locking rod 44 from the first locking hole 46. Then rotate the first rectangular block 43 to rotate it to the other side. Then pull the protective outer frame 42 downward to separate the first annular groove 9 from the first annular block 8. Then remove the lamp cover 7 and clean the dust.

[0043] S2. When dimming is required, rotate the threaded clamp 55 to move the rubber bonding block 57, thereby separating the rubber bonding block 57 from the second annular block 51. Then push the dimming plate 515 so that the dovetail slide rod 53 can slide in the second annular groove 52. When it slides to the appropriate position, rotate the threaded clamp 55 to fix the rubber bonding block 57 to the second annular block 51, thus completing the adjustment. When the dimming plate 515 needs to be disassembled, pull the second locking rod 511 outward to separate the second locking rod 511 from the first through hole 510 and the second through hole 516. Then pull the dimming plate 515 downward to separate the rectangular locking block 513 from the rectangular locking frame 59, thus completing the disassembly.

[0044] S3. When it is necessary to install the lamp holder 2, the sliding block 613 can be pushed according to the reserved hole, so that the sliding block 613 can slide in the rectangular slide groove 612, which in turn can drive the dovetail slider 618 to slide in the slide groove 617. When it slides to the appropriate position, the screw 615 is drilled in to fix it to the roof. Then, the annular sealing block 611 on the rubber round plate 610 is inserted into the annular sealing groove 620, and the round block 61 is inserted into the lamp holder 2, so that the round rod 62 can pass through the first slot 68. Then, the round block 61 is rotated so that the round rod 62 is inserted into the second slot 69. Then, the round locking rod 67 is inserted into the round hole 63.
