Description

Technical Field

[0001] This utility model relates to the field of LED lighting fixtures, specifically to an LED lighting fixture with a long service life and easy replacement. Background Technology

[0002] LED lighting fixtures, with their numerous advantages such as high efficiency, energy saving, environmental friendliness, and durability, have been widely used in various scenarios including homes, businesses, and industries. As people's demands for lighting quality and energy conservation continue to rise, the market demand for LED lighting fixtures continues to grow. To meet the diverse lighting needs of different locations, various types of LED lighting fixtures are constantly being innovated and updated.

[0003] The prior art disclosed in patent publication (announcement) number CN220488956U is an LED lamp fixture that facilitates LED lamp replacement, including a base with an opening on the side of the base. A connecting frame is installed in the opening of the base, and a terminal block is fixed to the top of the opening on the side of the base. A lamp cover is threadedly fixed to the bottom of the base. The connecting frame includes a fixing frame, a lamp tube installed inside the fixing frame, a locking block set on the top of the fixing frame, and a conductive plate installed on the top of the locking block. The terminal block includes a junction box and a wiring socket installed at the bottom of the junction box. The wiring at the bottom of the wiring socket is engaged with the conductive plate, and the wiring socket connects the conductive plate to the wiring in the junction box.

[0004] The aforementioned patent document discloses an LED lamp that facilitates LED replacement. While this solves the problem of inconvenient LED replacement in existing technologies, its shortcomings are as follows:

[0005] The aforementioned patented device lacks an effective heat dissipation design. In actual use, LED lights generate a large amount of heat when emitting light. If this heat cannot be dissipated in time, it will accumulate inside, keeping critical components such as the LED chips in a high-temperature environment for extended periods. This will accelerate the aging of electronic components, reduce luminous efficiency and stability, and significantly shorten the overall lifespan of the LED lights.

[0006] Furthermore, in the aforementioned patent, the lampshade is connected to the base by a threaded fixing method, which is complicated to disassemble and inconvenient for cleaning. During daily use, the surface of the lampshade is easily contaminated with dust, oil and other impurities. If it is not cleaned in time, it will not only affect the appearance of the lamp, but also reduce the light transmittance, ultimately affecting the lighting effect.

[0007] Therefore, we have made improvements to this and proposed an LED light fixture with a long service life and easy replacement. Utility Model Content

[0036] To address the technical problems in the background section, the following LED lighting fixtures with long service life and easy replacement are provided:

[0037] Combination Figure 1 - Figure 6As shown, this utility model provides an LED lamp with a long service life and easy replacement, including a ceiling 1. A fixing frame 2 is fixedly installed on the lower surface of the ceiling 1, and a lamp plate 3 is fixedly installed inside the fixing frame 2. A lamp cover 4 is installed on the lower surface of the fixing frame 2, and a heat dissipation mechanism 5 is provided on the inner wall of the fixing frame 2. A connecting mechanism 6 is provided between the fixing frame 2 and the lamp cover 4. The heat dissipation mechanism 5 includes four grooves 501, which are evenly distributed on the surface of the fixing frame 2. Four heat-conducting plates 502 are provided on the inner wall of the fixing frame 2, and the heat-conducting plates 502 are located on one side of the grooves 501. The heat-conducting plates 502 are arc-shaped, and a number of heat dissipation fins 503 are fixedly installed on the arc surface of the heat-conducting plates 502. The heat dissipation fins 503 are located inside the grooves 501.

[0038] In this embodiment: the fixed frame 2, which is stably installed on the lower surface of the ceiling 1, provides a solid support structure for the lamp. The lamp panel 3, which is fixedly installed inside, can stably output light. The inner wall of the fixed frame 2 is provided with a heat dissipation mechanism 5. Four evenly distributed grooves 501 cooperate with the arc-shaped heat conduction plate 502. The heat dissipation fins 503, which are densely arranged on the arc surface of the heat conduction plate 502, are placed inside the grooves 501, which can greatly increase the heat dissipation area and quickly dissipate the heat generated by the lamp panel 3. This effectively avoids the lamp from experiencing performance degradation or even damage due to overheating, greatly extends the service life of the lamp, and ensures the stability and reliability of the lamp during long-term use.

[0039] In a preferred embodiment, protrusions 504 are fixedly installed on both sides of the heat-conducting plate 502, and mounting grooves 505 are provided on the inner wall of the fixing frame 2. The protrusions 504 and the mounting grooves 505 are connected by a snap-fit ​​connection.

[0040] In this embodiment, the heat-conducting plate 502 is quickly installed onto the inner wall of the fixed frame 2 by engaging with the protrusions 504 on both sides of the heat-conducting plate 502 and the mounting grooves 505 on the inner wall of the fixed frame 2. This makes the operation simple and greatly improves the installation efficiency.

[0041] In a preferred embodiment, the heat-conducting plate 502 is made of copper and the heat dissipation fins 503 are made of aluminum.

[0042] In this embodiment: the heat-conducting plate 502 is made of copper, which has an extremely high thermal conductivity, enabling it to quickly and efficiently conduct the heat generated by the lamp panel 3 away, ensuring that heat does not accumulate inside the lamp. The heat dissipation fins 503 are made of aluminum, which is lightweight, has high heat dissipation efficiency, and good processing performance, allowing it to be processed into thin and dense fin structures, greatly increasing the heat dissipation area. Together, these materials significantly improve the heat dissipation effect of the lamp.

[0043] In a preferred embodiment, the connecting mechanism 6 includes a slide groove 601, which is formed on the inner wall of the fixed frame 2. The top of the slide groove 601 is provided with a plurality of slots 602 and a plurality of slots 603. The slots 602 are connected to the upper surface of the fixed frame 2. A plurality of L-shaped blocks 604 are fixedly installed on the lower surface of the lampshade 4. The L-shaped blocks 604 are slidably connected to the slots 602, and one end of the L-shaped blocks 604 is engaged with the slots 603.

[0044] In this embodiment, several L-shaped locking blocks 604 fixed on the lower surface of the lampshade 4 can slide smoothly along the slot 602. After sliding to the appropriate position, the lampshade 4 is rotated to make the L-shaped locking blocks 604 rotate. One end of the L-shaped locking block 604 is engaged with the slot 603. The whole process is simple and quick to operate, and the connection is stable after engagement, effectively preventing the lampshade 4 from loosening and falling off during use.

[0045] In a preferred embodiment, a connecting ring 605 is slidably connected inside the slide groove 601, and a first spring 606 is fixedly installed between the lower surface of the connecting ring 605 and the inner wall of the slide groove 601.

[0046] In this embodiment: When installing the lampshade 4, the L-shaped locking block 604 first pushes the connecting ring 605 upward. When one end of the L-shaped locking block 604 is inserted into the slot, the first spring 606 will press against the connecting ring 605 with its own elasticity, and the connecting ring 605 will press against the L-shaped locking block 604, enhancing the stability of the entire connection structure and ensuring that the lampshade 4 will not easily shake or loosen during daily use. For disassembly, simply push the connecting ring 605 upward and then rotate it to remove the L-shaped locking block 604 from the slot 602.

[0047] In a preferred embodiment, a connecting groove 607 is provided on the lower surface of the lampshade 4, and a sealing ring 608 is slidably connected inside the connecting groove 607. A second spring 609 is fixedly installed between the surface of the sealing ring 608 and the inner wall of the connecting groove 607.

[0048] In this embodiment: when the lampshade 4 is installed, the sealing ring 608 is squeezed, causing the second spring 609 to deform. When the L-shaped block 604 is inserted into the slot 606, the second spring 609 will press against the sealing ring 608 with its own elasticity, so that the sealing ring 608 fits tightly against the surface of the fixing frame 2, improving the dustproof and moisture-proof capabilities of the lamp, ensuring the safe operation of the internal electronic components, extending the service life of the lamp, and avoiding the problem of reduced light transmittance due to dust accumulation due to good sealing.

[0049] Specifically, the working principle of this solution is as follows:

[0050] When the lamp is working, the lamp panel 3 emits light and generates a large amount of heat. At this time, the heat dissipation mechanism 5 comes into play. The heat conduction plate 502, thanks to the high thermal conductivity of copper, quickly conducts the heat from the lamp panel 3 to the curved surface. The densely arranged aluminum heat dissipation fins 503 on the curved surface are placed in the groove 501, which greatly increases the heat dissipation area, quickly dissipates the heat, prevents the lamp from overheating, ensures its stable operation, and extends its service life.

[0051] When installing the lampshade 4, align the L-shaped locking block 604 on the lower surface of the lampshade 4 with the slot 602 at the top of the sliding groove 601 on the inner wall of the fixing frame 2 and slide it in. At the same time, push the connecting ring 605 upward, compressing the first spring 606. After the L-shaped locking block 604 has slid to the appropriate position, rotate the lampshade 4 so that one end of the L-shaped locking block 604 is engaged in the slot 603. The elastic force of the first spring 606, through the action of the connecting ring 605, enhances the connection stability. During installation, the lampshade 4 compresses the sealing ring 608, deforming the second spring 609. When the L-shaped locking block 604 is engaged in the slot 603, the elastic force of the second spring 609 makes the sealing ring 608 fit tightly against the surface of the fixing frame 2, forming a good seal, improving dustproof and moisture-proof capabilities, ensuring the safety of internal components, and preventing dust accumulation from affecting light transmittance, thus ensuring the lighting effect.

[0052] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0053] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
