Description

Technical Field

[0001] This utility model relates to the field of LED ceiling light technology, and in particular to a high-efficiency LED ceiling light. Background Technology

[0002] An LED (Light Emitting Diode) is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light; the heart of an LED is a semiconductor chip. LED light sources have advantages such as using low-voltage power supplies, low energy consumption, wide applicability, high stability, short response time, no environmental pollution, and multi-color emission.

[0003] Chinese patent CN203615206U discloses a high-efficiency LED ceiling light, including a chassis, lampshade, lamp head, LED lights, and a driver power supply. The lampshade is screwed onto the chassis. The center of the chassis bulges upward into a truncated cone, creating an upward-facing concave portion on the bottom surface of the chassis. The lamp head is connected to the concave portion of the chassis, and the driver power supply is installed inside the lamp head. The LED lights are evenly distributed on the upper surface of the chassis, the top surface of the truncated cone, and the conical surface. An annular reflective paper surrounds the inner edge of the chassis, with the reflective surface of the reflective paper perpendicular to the plane of the chassis. The LED lights installed in the central area of ​​the upper surface of the chassis enhance the brightness of the central area of ​​the ceiling light. The LED lights on the conical surface of the truncated cone not only enhance the brightness of the ceiling light outside the central area but also further enhance the brightness of the central area of ​​the ceiling light through reflection from the reflective paper around the chassis.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: existing high-efficiency LED ceiling lights cannot quickly dissipate heat from their internal components, which can easily lead to excessive internal temperatures and damage to the equipment. In addition, the ceiling lights cannot be quickly disassembled and installed, increasing maintenance time and reducing maintenance efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that ceiling lights cannot improve heat dissipation and allow for quick disassembly and installation, and to propose a high-efficiency LED ceiling light.

[0006] The technical solution of this utility model: A high-efficiency LED ceiling light, comprising a ceiling light body and a mounting plate disposed on the top of the ceiling light body; further comprising:

[0007] The heat dissipation mechanism, which is threaded onto the mounting plate, is used to absorb the heat inside the ceiling light body to evaporate the water inside, and then the heat is discharged to the top.

[0008] The disassembly mechanism is located on the top of the mounting plate and is used to install the ceiling light body onto the ceiling by pressing.

[0009] The system includes heat pipes, which are threaded onto the mounting plate. A heat-conducting plate is located at the bottom of the heat pipe, and a condenser platform is located at the top inside the heat pipe. Four heat pipes are arranged in a ring around the mounting plate. The inside of each heat pipe is filled with a working fluid. The heat-conducting plate is made of a heat-conducting material. When the ceiling light body generates a large amount of heat, the heat enters the heat pipe through the heat-conducting plate, thereby evaporating the working fluid. The evaporated vapor floats onto the condenser platform, where it absorbs the heat of the vapor and is converted back into liquid. The condenser platform is recessed in the middle, and the liquid slides down the slope of the condenser platform onto the inner wall of the heat pipe, eventually falling into the working fluid at the bottom of the heat pipe.

[0010] Preferably, the heat dissipation mechanism includes a heat dissipation component and a fluid exchange component;

[0011] The heat dissipation component is set on the heat pipe to dissipate the heat inside the heat pipe and reduce the heat inside the ceiling light body.

[0012] The fluid exchange assembly is located on the side and is used to open the heat pipe to replace or replenish the internal working fluid.

[0013] Preferably, the heat dissipation assembly includes a connecting block, a heat dissipation platform, and a heat-conducting rod;

[0014] The connecting block is located inside the heat pipe, the flow channel is located at the end of the connecting block away from the heat pipe, the heat-conducting rod is located on the top of the condensation platform, and a rotating block is located on the top of the heat pipe.

[0015] Preferably, the fluid changing assembly includes a fixing frame, a telescopic tube, and a spring;

[0016] The fixing bracket is located inside the heat pipe, the telescopic tube is located inside the fixing bracket, the spring is located outside the telescopic tube, and a locking block is provided at the end of the telescopic tube away from the fixing bracket.

[0017] Preferably, the disassembly mechanism includes a connecting platform, a fixed shaft, a semi-circular block, and a disassembly assembly;

[0018] The connecting platform is located on the top of the mounting plate, the fixed shaft is located on the top of the connecting platform, and the semi-circular block is located on the top of the fixed shaft;

[0019] The disassembly assembly is located on the outside of the fixed shaft and is used to install and remove the ceiling light body by pressing.

[0020] Preferably, the disassembly assembly includes a disassembly ring, a sleeve, a telescopic tube, and a fixing block;

[0021] The disassembly ring is slidably mounted on the outside of the fixed shaft, the sleeve is located on the outside of the fixed shaft, the fixing block is mounted on the side of the sleeve, the second telescopic tube is mounted on the side of the fixing block, the second spring is mounted on the outside of the second telescopic tube, and a trapezoidal block is mounted on the end of the second telescopic tube away from the fixing block.

[0022] Preferably, the bottom of the mounting plate is provided with a ring-shaped light panel, and the bottom of the ring-shaped light panel is provided with light fixtures, with multiple light fixtures arranged in a ring around the ring-shaped light panel.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. Through the heat dissipation mechanism, heat is transferred to the internal working fluid through the heat conduction plate, and then dissipated through the evaporation and condensation of the working fluid. This can quickly transfer the heat generated by the LED chip to the outside, avoiding heat accumulation near the lamp and thus reducing the chip junction temperature. In addition, the ring-shaped heat pipe can evenly distribute heat to the outside through the heat conduction rod, avoiding chip failure or aging of the packaging material due to local overheating. At the same time, the setting of the condensation platform and the flow channel can make the working fluid temporarily stratify, allowing the condensed liquid to flow to the surroundings, while the uncondensed liquid is distributed in the center to evaporate and absorb heat, further enhancing the heat dissipation effect.

[0025] 2. By using the disassembly mechanism, the trapezoidal block is squeezed by pressing the connecting platform. The trapezoidal block, semi-circular block and disassembly ring work together to achieve quick disassembly and installation. This can be done with just one hand by pressing or pushing, without the need for tools. The operation time is shortened and "foolproof" installation is achieved. This avoids damage or safety hazards caused by improper operation, reduces the time spent at height and improves safety. Attached Figure Description

[0031] Example 1

[0032] like Figures 1-3 As shown, the present invention proposes a high-efficiency LED ceiling light, including a ceiling light body 1, a mounting plate 6 disposed on the top of the ceiling light body 1, a heat dissipation mechanism, a disassembly mechanism, and a heat pipe 401.

[0033] The heat dissipation mechanism is threaded on the mounting plate 6 and is used to absorb the heat inside the ceiling light body 1 to evaporate the water inside, and then rise to the top to dissipate the heat.

[0034] The disassembly mechanism is located on the top of the mounting plate 6 and is used to install the ceiling light body 1 onto the ceiling by pressing it.

[0035] Heat pipe 401 is threaded onto mounting plate 6. A heat-conducting plate 410 is provided at the bottom of heat pipe 401. A condenser platform 402 is provided at the top of the inner side of heat pipe 401. Four heat pipes 401 are arranged in a ring around mounting plate 6. The inside of heat pipe 401 is filled with working fluid. The heat-conducting plate 410 is a heat-conducting material. After the ceiling light body 1 generates a large amount of heat, the heat enters the heat pipe 401 through the heat-conducting plate 410, thereby evaporating the working fluid. The evaporated vapor floats onto condenser platform 402. Condenser platform 402 absorbs the heat of the vapor and converts it back into liquid. The middle of condenser platform 402 is concave. The liquid slides down the inclined surface of condenser platform 402 onto the inner wall of heat pipe 401 and finally falls into the working fluid at the bottom of heat pipe 401.

[0036] The heat dissipation mechanism includes a heat dissipation component and a liquid exchange component. The heat dissipation component is mounted on the heat pipe 401 and is used to dissipate heat from inside the heat pipe 401 to reduce the heat inside the ceiling light body 1. The liquid exchange component is located on the side and is used to open the heat pipe 401 to replace or replenish the working liquid inside. The heat dissipation component includes a connecting block 409, a flow guide platform 408, and a heat-conducting rod 403. The connecting block 409 is located inside the heat pipe 401, and the flow guide platform 408 is located at the end of the connecting block 409 away from the heat pipe 401. The flow guide platform 408 is cone-shaped and hollow in the middle, so that when the working liquid evaporates, it flows through the flow guide platform 408 to the center of the condensation platform 402, enhancing the condensation effect. Furthermore, after the vapor condenses into droplets, it will not fall into the center of the bottom liquid, thus ensuring that the center of the bottom working liquid... Part of the liquid absorbs heat and evaporates, while the condensed liquid remains around the perimeter. The heat-conducting rod 403 is positioned on top of the condensing platform 402. A rotating block 411 is positioned on top of the heat pipe 401. By holding the rotating block 411, the heat pipe 401 can be rotated, thereby allowing the heat pipe 401 to be installed and removed from the mounting plate 6. After the working liquid absorbs heat and converts it into steam, it dissipates heat on the condensing platform 402. The condensing platform 402 absorbs heat and transfers it to the heat-conducting rod 403, which then guides the heat to the outside, thereby enhancing the heat dissipation effect of the ceiling light body 1. The fluid replacement assembly includes a mounting bracket 404, a telescopic tube 405, and a spring 406. The mounting bracket 404 is located inside the heat pipe 401, the telescopic tube 405 is located inside the mounting bracket 404, and the spring 406 is located outside the telescopic tube 405. A locking block 407 is provided at the end of the telescopic tube 405 away from the mounting bracket 404. In its natural state, the locking block 407 and the outer wall of the heat pipe 401 are fully engaged and connected, thus preventing heat and fluid leakage. When fluid needs to be added or replaced, the locking block 407 is pressed, which causes the spring 406 and the telescopic tube 405 to compress and disengage from the outer side of the heat pipe 401, allowing fluid to be added to or poured out of the heat pipe 401.

[0037] The bottom of the mounting plate 6 is provided with a ring-shaped light plate 2, and the bottom of the ring-shaped light plate 2 is provided with a light fixture 3. Multiple light fixtures 3 are arranged in a ring around the ring-shaped light plate 2.

[0038] Example 2

[0039] like Figure 4 As shown, this utility model proposes a high-efficiency LED ceiling light. Compared with Embodiment 1, this embodiment details the structure of the disassembly mechanism.

[0040] The disassembly mechanism includes a connecting platform 501, a fixed shaft 502, a semi-circular block 504, and a disassembly assembly; the connecting platform 501 is located on the top of the mounting plate 6, the fixed shaft 502 is located on the top of the connecting platform 501, and the semi-circular block 504 is located on the top of the fixed shaft 502; the disassembly assembly is located on the outside of the fixed shaft 502 and is used to install and disassemble the ceiling light body 1 by pressing. The disassembly assembly includes a disassembly ring 503, a sleeve 505, a second telescopic tube 507, and a fixing block 506. The disassembly ring 503 is slidably disposed on the outside of the fixed shaft 502. The sleeve 505 is located on the outside of the fixed shaft 502. The fixing block 506 is disposed on the side of the sleeve 505. The second telescopic tube 507 is disposed on the side of the fixing block 506. The second spring 508 is disposed on the outside of the second telescopic tube 507. A trapezoidal block 509 is disposed at the end of the second telescopic tube 507 away from the fixing block 506. The top of the sleeve 505 is connected to the ceiling. When the ceiling light body 1 is pressed upwards aligned with the axis of the sleeve 505, the ceiling light body 1 moves the connecting platform 501 and the semi-circular block 504. When the semi-circular block 504 moves inside the sleeve 505, it moves the trapezoidal block 509 to both sides until it reaches the... When the semicircular block 504 is at its bottom, it cannot press the trapezoidal block 509. The trapezoidal block 509 rebounds under the action of the spring 508 and gets stuck at the bottom of the semicircular block 504, thus connecting the ceiling light to the ceiling. When the ceiling light body 1 needs to be disassembled, continue to press the ceiling light body 1 upward so that the trapezoidal block 509 contacts the disassembly ring 503. The disassembly ring 503 is divided into upper and lower parts, both of which are inclined. The trapezoidal block 509 moves along the inclined surface to the bottom of the disassembly ring 503, and then pulls the ceiling light body 1 downward to move the disassembly ring 503 to the top of the semicircular block 504 until it is disassembled from the semicircular block 504. The bottom of the semicircular block 504 is provided with a slot, which can be engaged with the upper part of the disassembly ring 503 to facilitate the disassembly work.

[0041] In summary, when using this utility model, to install the ceiling light body 1, align the connecting platform 501 with the axis of the sleeve 505 and press the ceiling light body 1 upwards. The ceiling light body 1 drives the connecting platform 501 and the semi-circular block 504 to move. When the semi-circular block 504 moves inside the sleeve 505, it drives the trapezoidal block 509 to move to both sides until it reaches the bottom of the semi-circular block 504. At this point, the trapezoidal block 509 rebounds under the action of the second spring 508 and thus locks into the bottom of the semi-circular block 504, thereby connecting the ceiling light to the ceiling. When the ceiling light body 1 is working, it generates heat. The heat enters the heat pipe 401 through the heat conduction plate 410, thereby evaporating the working liquid. The evaporated vapor floats onto the condenser platform 402, where the condenser platform 402 absorbs the heat of the vapor and converts it back into liquid, which then flows down the condenser platform. The inclined surface of platform 402 slides into the working liquid at the bottom. The heat absorbed by the condensing platform 402 is discharged outward through the heat conduction rod 403. When it is necessary to add or replace the working liquid, press the locking block 407. The locking block 407 drives the spring 406 and the telescopic tube 405 to compress, thereby disengaging from the outside of the heat pipe 401. Then, liquid can be added to or poured out of the heat pipe 401. When it is necessary to disassemble the ceiling light body 1, continue to press the ceiling light body 1 upward, so that the trapezoidal block 509 contacts the disassembly ring 503. The trapezoidal block 509 moves along the inclined surface to the bottom of the disassembly ring 503, and then pulls the ceiling light body 1 downward, thereby moving the disassembly ring 503 to the top of the semicircular block 504 until it disengages from the semicircular block 504, thereby disengaging the connecting platform 501 from the sleeve 505, thus completing the disassembly.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
