Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of downlights, in particular to a dustproof LED downlight. Background Art
[0002] Surface-mounted downlights are lighting fixtures that are suspended from the ceiling via hangers. Surface-mounted downlights have a tube body set outside the light source for ease of installation and for decorative purposes. However, the tube body is relatively closed, with the top close to the roof and the bottom fitted to the lamp body, affecting the heat dissipation of the light source.
[0003] At present, fins can be set on the side walls, but this heat dissipation method is poor, so more people choose to open holes in the side walls. However, dust is easy to enter in the use environment and adhere to the inside of the light source for a long time, affecting the service life. Summary of the Invention
[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a dust-proof LED downlight with a simple structure, easy installation and long service life.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] A dustproof LED downlight comprises a downlight body and a lamp holder, wherein the lamp holder comprises an LED light source and a reflector cup, and a decorative ring is fixed to the end of the reflector cup.
[0007] A partition is fixed in the cylinder, and a wire hole is provided on the partition. The LED light source, circuit board and driver are electrically connected, and the circuit board and driver are installed on the partition; heat dissipation holes are provided on the partition; a plurality of side holes are provided in the circumferential direction of the upper end of the cylinder; a convex ring is provided at the lower end of the cylinder protruding inward, the decorative ring is in contact with the convex ring and the decorative ring is located in the cylinder, and also includes a clamping structure for clamping the decorative ring and the convex ring.
[0008] In this way, the compression structure presses the decorative ring and the convex ring tightly, allowing the lamp holder to be installed in the barrel and pass the wires through the wire hole. During use, heat dissipation can be achieved through the heat dissipation holes and side holes, and the partitions are separated to reduce dust from entering the lamp holder through the side holes, thereby better preventing dust.
[0009] Wherein, the middle portion of the partition is protruding upward.
[0010] Wherein, a rubber ring is installed at the wire hole.
[0011] Among them, the clamping structure includes a pressing ring, and a limiting ring is provided on the pressure ring facing the interval between the cylinder and the decorative ring. The pressure ring, the convex ring and the limiting ring are provided with air holes facing each other, and the convex ring and the limiting ring are bonded with a dustproof net facing the air holes. The pressure ring, the convex ring and the limiting ring are provided with a number of threaded holes facing each other, and the pressure ring, the convex ring and the limiting ring are fixedly connected by screws.
[0012] Wherein, a hanger is fixedly mounted on the cylinder, and a mounting hole is provided on the hanger.
[0013] In summary, the dustproof LED downlight has the advantages of simple structure, easy installation and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.
[0023] like Figure 1-8 As shown, a dustproof LED downlight comprises a barrel 1 and a lamp holder 2. The lamp holder comprises an LED light source and a reflector cup. A decorative ring 3 is fixed to the end of the reflector cup.
[0024] A partition 4 is fixed in the cylinder, and a wire hole 5 is provided on the partition. The LED light source, circuit board and driver are electrically connected, and the circuit board and driver are mounted on the partition; a heat dissipation hole 6 is provided on the partition; a plurality of side holes 7 are provided in the circumferential direction of the upper end of the cylinder; a convex ring 8 is provided at the lower end of the cylinder protruding inward, and the decorative ring is in contact with the convex ring and is located in the cylinder, and also includes a clamping structure for clamping the decorative ring and the convex ring.
[0025] In this way, the compression structure presses the decorative ring and the convex ring tightly, allowing the lamp holder to be installed in the barrel and pass the wires through the wire hole. During use, heat dissipation can be achieved through the heat dissipation holes and side holes, and the partitions are separated to reduce dust from entering the lamp holder through the side holes, thereby better preventing dust.
[0026] During implementation, the middle portion of the partition is protruded upwards. Since the center of the partition is protruding upwards, even if dust enters the upper portion of the partition through the side holes, the partition can block the dust. The heat dissipation holes are concentrated in the center of the partition and protrude, which can better achieve dustproofing.
[0027] During implementation, a rubber ring is installed at the wire hole to seal the wire hole, and the wire passes through the rubber ring to reduce dust from entering the lamp holder through the wire hole.
[0028] During implementation, the clamping structure includes a pressure ring 9, which is provided with a limit ring 10 protruding from the gap between the barrel and the decorative ring. Air holes 11 are provided opposite the pressure ring, the convex ring, and the limit ring. Dust screens are bonded to the convex ring and the limit ring opposite the air holes. Several threaded holes 12 are provided opposite the pressure ring, the convex ring, and the limit ring. The pressure ring, the convex ring, and the limit ring are fixedly connected by screws. After the lamp holder is placed in the barrel, the pressure ring is aligned between the lamp holder and the barrel, the limit ring is inserted into the gap between the barrel and the decorative ring, the pressure ring is rotated so that the threaded holes are aligned, and the pressure ring, the convex ring, and the limit ring are fixedly connected using screws.
[0029] During implementation, a hanger 13 is fixedly mounted on the cylinder, and a mounting hole is provided on the hanger for easy installation.
[0030] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
