Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to an LED ceiling light. Background Technology

[0002] Ceiling lights are a type of lighting fixture. As the name suggests, they are called ceiling lights because the top of the fixture is relatively flat and the bottom is completely flush with the ceiling during installation. Light sources include ordinary incandescent bulbs, fluorescent lamps, high-intensity discharge lamps, halogen lamps, and LEDs. Currently, the most popular ceiling lights on the market are LED ceiling lights, which are frequently chosen for homes, offices, entertainment venues, and various other places.

[0003] In existing technology, a PC plastic inner cover with a fire-resistant rating of UL94-5VA is added inside the ceiling light to improve the fire resistance of the entire LED ceiling light fixture. However, this high-fire-resistant PC plastic is very expensive, resulting in high material costs for the light fixture. In addition, it requires the opening of plastic molds, and because LED ceiling lights are relatively large, the mold costs are also very high.

[0004] A search revealed that Chinese patent CN206617848U discloses an LED ceiling light. By setting the inner glass cover between the light diffuser and the circuit board, the LED ceiling light can improve its electric shock resistance and fire resistance, while also avoiding the need for mold making and reducing production costs.

[0005] In actual use, after a period of use, dust and debris tend to accumulate on the outside of the LED ceiling light cover. Since the cover needs to be removed for cleaning, the disassembly process of some ceiling light covers is quite cumbersome. This can lead to damage to the cover or base due to improper operation during disassembly, and may even cause safety accidents such as electric shock. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an LED ceiling light to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An LED ceiling light includes a fixed base, a connecting ring fixedly connected to the bottom end of the fixed base, a plurality of connecting parts fixedly connected to the outside of the fixed base, two limiting shells fixedly connected to the outside of the fixed base, the limiting shells being symmetrically distributed on the outside of the fixed base, a disassembly assembly installed inside the fixed base, a lampshade installed below the fixed base, and a heat dissipation mechanism provided below the fixed base.

[0009] The disassembly assembly includes a gear, which is rotatably connected to the interior of the fixed base. Two racks mesh with the outer side of the gear. A first connecting plate is fixedly connected to one side of the racks. Two springs are fixedly connected to one side of the first connecting plate. One end of each spring is fixedly connected to the interior of the fixed base. A slide rod is fixedly connected to one side of the first connecting plate. The slide rod is slidably connected inside the fixed base. A second connecting plate is fixedly connected to one end of the slide rod. A pull rod is fixedly connected to one side of the second connecting plate. The pull rod is slidably connected to the interior of the limiting shell. An insertion rod is fixedly connected to the other side of the second connecting plate. A slider is engaged with the outer side of the insertion rod. The slider is fixedly connected to the upper surface of the lampshade. Two grooves are formed inside the connecting ring. The slider is slidably connected inside the grooves. The insertion rod extends through the limiting shell and the connecting ring to the inside of the grooves.

[0010] By adopting the above technical solution, the connecting ring can be quickly separated from the lampshade, the lamp can be cleaned more quickly, and the lampshade and LED lights can be cleaned more quickly.

[0011] As a further description of the above technical solution: the heat dissipation mechanism includes a connecting bracket, which is fixedly connected to the lower surface of the fixed base. Two LED lights are fixedly connected to the bottom of the connecting bracket. Heat dissipation fins are fixedly connected to the upper surface of the connecting bracket. Heat dissipation fans are provided on both sides of the LED lights. The heat dissipation fans are fixedly connected to the upper surface of the connecting bracket. Two air outlets and air inlets are opened on the outer side of the connecting ring. The two air outlets and air inlets are symmetrically distributed on the outer side of the connecting ring.

[0012] By adopting the above technical solution, the heat generated by the two LED lights can be dissipated into the outside air, thereby enabling the two LED lights to maintain a stable temperature during use.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up disassembly components, compared with existing technologies, users can easily clean the lampshade and remove accumulated dust and dirt, and complete the cleaning, maintenance and replacement of the lampshade and LED lights more quickly. At the same time, it can reduce the risk of accidental electric shock when disassembling the lampshade, thereby improving the safety of operation.

[0015] 2. By setting up a heat dissipation mechanism, compared with existing technologies, the connecting ring and the inside of the lamp cover can maintain a stable temperature, reduce light decay and malfunctions caused by overheating, thereby extending the overall service life of the lamp. At the same time, it can reduce safety hazards caused by high temperature and improve the safety of use. Attached Figure Description

[0024] 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.

[0025] The embodiments disclosed in this application are as follows: Figure 1-6 An LED ceiling light shown includes a fixed base 1, a connecting ring 2 fixedly connected to the bottom of the fixed base 1, multiple connecting pieces 3 fixedly connected to the outside of the fixed base 1, two limiting shells 4 fixedly connected to the outside of the fixed base 1, the limiting shells 4 being symmetrically distributed on the outside of the fixed base 1, a disassembly assembly installed inside the fixed base 1, a lampshade 5 installed below the fixed base 1, and a heat dissipation mechanism provided below the fixed base 1.

[0026] The disassembly assembly includes a gear 6, which is rotatably connected to the inside of the fixed base 1. Two racks 7 mesh with the outside of the gear 6. A first connecting plate 8 is fixedly connected to one side of the racks 7. Two springs 9 are fixedly connected to one side of the first connecting plate 8. One end of each spring 9 is fixedly connected to the inside of the fixed base 1. A slide rod 10 is fixedly connected to one side of the first connecting plate 8 and slides inside the fixed base 1. A second connecting plate 11 is fixedly connected to one end of the slide rod 10. A pull rod 12 is fixedly connected to one side of the second connecting plate 11 and slides inside the limiting housing 4. An insert rod 13 is fixedly connected to the other side of the second connecting plate 11. A slider 14 is engaged on the outside of the insert rod 13 and is fixedly connected to the upper surface of the lampshade 5. Two grooves 15 are formed inside the connecting ring 2, and the slider 14 slides inside the grooves 15. The insert rod 13 extends through the limiting housing 4 and the connecting ring 2 to the inside of the grooves 15. By pulling one of the pull rods 12, the pull rod 12 passes through the second connecting plate 11. The insertion rod 13 can move inside the limiting housing 4 and separate from the groove on one side of the slider 14. At the same time, the second connecting plate 11 and the pulling slide rod 10 slide inside the fixed base 1. The slide rod 10 can drive the rack 7 to move through the first connecting plate 8 and mesh with the gear 6, so that the gear 6 can rotate inside the fixed base 1. At the same time, the movement of the first connecting plate 8 can squeeze the two heat dissipation fins 18 inside the fixed base 1. When the gear 6 rotates, it can mesh and drive another rack 7 to move, so that the other rack 7 can push the other slide rod 10 to slide inside the fixed base 1, so that the other insertion rod 13 can separate from the slider 14. Then, the lamp cover 5 is rotated, and the lamp cover 5 can drive the two sliders 14 to slide inside the slide groove 15. The sliders 14 can separate from the slide groove 15 through the opening on one side of the slide groove 15, so that the lamp cover 5 is separated from the connecting ring 2, which makes it easy and quick for users to install and remove the lamp cover 5, and allows users to easily clean it.

[0027] Reference Figure 5 and 1As shown, the heat dissipation mechanism includes a connecting bracket 16, which is fixedly connected to the lower surface of the fixed base 1. Two LED lights 17 are fixedly connected to the bottom of the connecting bracket 16. Heat dissipation fins 18 are fixedly connected to the upper surface of the connecting bracket 16. Cooling fans 19 are provided on both sides of the LED lights 17 and are fixedly connected to the upper surface of the connecting bracket 16. Two air outlets 20 and air inlets 21 are opened on the outer side of the connecting ring 2. The two air outlets 20 and air inlets 21 are symmetrically distributed on the outer side of the connecting ring 2. The heat dissipation fins 18 can dissipate the heat transferred from the LED lights 17 to the surface of the connecting bracket 16. The heat dissipation fins 18 can dissipate the heat inside the connecting bracket 16. The rotation of the two cooling fans 19 can quickly dissipate the hot air inside the connecting bracket 16 to the outside air through the two air outlets 20. The two air inlets 21 can facilitate the flow of air inside the connecting ring 2 and the lamp cover 5, so that the connecting ring 2 and the lamp cover 5 can maintain a stable temperature, which can reduce the safety hazards caused by high temperature and improve the safety of use.

[0028] Working principle of this utility model: This utility model designs an LED ceiling light, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, when the lamp cover 5 needs to be disassembled and cleaned after a period of use, one of the pull rods 12 is pulled first, causing the pull rod 12 to drive the insert rod 13 to move inside the limiting housing 4 via the second connecting plate 11. At the same time, the second connecting plate 11 can drive the slide rod 10 to move. The slide rod 10 can pull the rack 7 to move inside the fixed base 1 via the first connecting plate 8. While the first connecting plate 8 is moving, it can apply a squeezing force to the two springs 9 inside the fixed base 1. When the rack 7 moves, it can mesh and drive the gear 6 to rotate inside the fixed base 1, so that the gear 6 can mesh and drive the other rack 7 to move. The other rack 7 can push the other slide rod. 10 slides inside the fixed base 1. Similarly, another pull rod 12 can be pushed to drive another plug rod 13 to separate from the slider 14. After both plug rods 13 are separated from the slider 14, the lamp cover 5 can be rotated. The lamp cover 5 can drive the two sliders 14 to slide inside the slide groove 15. Through the opening at one end of the slide groove 15, the lamp cover 5 can be separated from the connecting ring 2, so that the lamp cover 5 can be cleaned. When installation is required, align the two sliders 14 with the opening at one end of the slide groove 15, and then rotate the lamp cover 5 so that the lamp cover 5 drives the two sliders 14 to slide inside the slide groove 15. Then pull the pull rod 12 again, and use the two plug rods 13 to insert into the groove on one side of the slider 14 to connect the lamp cover 5 and the connecting ring 2.

[0029] When the two LED lights 17 generate heat during use and need to dissipate it, the heat dissipation fins 18 can absorb the heat transferred from the LED lights 17 to the surface of the connecting bracket 16. At the same time, the heat dissipation fins 18 can dissipate the heat inside the connecting bracket 16. Then, the two cooling fans 19 are turned on. The heat dissipated by the heat dissipation fins 18 inside the connecting bracket 16 can be transferred to the outside air through the two air outlets 20, thereby reducing the temperature of the connecting ring 2 and the inside of the lamp cover 5.
