Description

Technical Field

[0001] This utility model relates to LED equipment, and more particularly to an LED lighting fixture with a stacked heat dissipation structure. Background Technology

[0002] Patent document CN202253495U discloses a fast-heat dissipation LED lamp, including a PCB substrate connectable to a power cord, LED beads mounted on the PCB substrate, and a lampshade covering the LED beads. It also includes a heat sink connected to the PCB substrate and connected to the backlight end of the lampshade. The lampshade is a heat-dissipating metal shell, and the heat sink is connected to the heat-dissipating metal shell. Heat emitted by the LED beads when emitting light is transferred through the PCB substrate to the heat-dissipating metal shell and the heat sink, where it is dissipated together by the heat sink and the lampshade, accelerating heat dissipation and keeping the LED lamp temperature at a relatively low value, slowing down light decay and extending the LED lamp's lifespan. However, this lamp's heat dissipation path is singular and inefficient, relying solely on the PCB substrate to conduct heat to the flared metal lampshade and the independent heat sink for passive heat dissipation. It lacks an active and efficient heat conduction mechanism, resulting in significant deficiencies in heat dissipation efficiency, speed, and reliability when dealing with the heat generated by high-power LEDs. Therefore, structural optimization is necessary to overcome these shortcomings. Utility Model Content

This multi-path heat dissipation mode, combining active guidance and passive enhancement, significantly improves overall heat dissipation efficiency, thereby directly ensuring the LED's operational stability and lifespan.

The heat dissipation component is installed in the stacked heat dissipation component and corresponds to the position of the light-emitting component. The heat dissipation component guides the heat generated by the light-emitting component to the stacked heat dissipation component.

[0034] In this embodiment, the support bearing assembly includes a support back plate 110, a support side frame 120, and support hoops 130. The support back plate is arranged vertically, and a pair of support side frames are provided. Each support side frame is arranged vertically and parallel to the support back plate. There are two sets of support hoops, and each set of support hoops is engaged with the edge of the support back plate and the support side frame.

[0035] The power supply drive assembly includes a power supply module 200, which is installed on the side of the support back plate and connected to the power source through wires. A gap is left between the power supply module and the support back plate, and the power supply module is supported by the support back plate. The structure and operating principle of the power supply module adopt existing technology, so they are not described in detail.

[0036] The adapter positioning assembly includes a positioning base 300. Both ends of the positioning base are connected to the support side frame, which supports it. One end of the positioning base is connected to the power supply module through a wire, and the other end has a screw-in slot to form a positioning space.

[0037] The light-emitting lighting assembly includes a light-emitting lamp head 410 and a lighting cover 420. The power input terminal of the light-emitting lamp head is screwed into a screw-in slot and connected to a positioning base. Its light-emitting end extends outward from the positioning base, and the positioning base supplies power to the light-emitting lamp head. A power supply module supplies power to the light-emitting lamp head and drives its operation through the positioning base. The lighting cover is mounted on a support side frame and wraps around the light-emitting end of the light-emitting lamp head, shielding and focusing the light. The light-emitting end is equipped with a light-emitting substrate and LED beads. Its structure and operating principle adopt existing technology and therefore are not described in detail.

[0038] The stacked heat dissipation assembly includes a heat dissipation plate 500. The heat dissipation plate is provided in a set. Each heat dissipation plate is connected to the support side frame at both ends and a heat dissipation gap is formed between adjacent heat dissipation plates. The positioning seat passes through the heat dissipation plate and the heat generated by the light head can be dissipated to the outside through the positioning seat and the heat dissipation plate.

[0039] In this embodiment, a toothed groove 510 is provided on the edge of the heat sink to increase its surface area. Simultaneously, an isolation strip 520 is provided within the toothed groove, and the side of the isolation strip has isolation fins 521. The isolation fins extend into the heat dissipation gap and abut against the side wall of the heat sink, thus stabilizing the heat dissipation gap. In this embodiment, a flow passage 530 is provided in the heat sink, allowing adjacent heat dissipation gaps to communicate with each other.

[0040] The heat dissipation assembly includes a heat pipe 600, which is a set. The inner end of each heat pipe is inserted into the support side frame and close to the light-emitting end of the lamp head. The outer end of each heat pipe passes through the middle of the heat sink body. The heat pipes conduct the heat generated at the light-emitting end to the heat sink body. One end of the heat pipe is in close contact with the light-emitting end of the lamp head. The working liquid encapsulated inside the heat pipe absorbs heat and evaporates rapidly into vapor. The other end extends into the lower-temperature heat sink body, where it releases the latent heat of vaporization and condenses back into liquid. The condensed liquid flows back through the capillary structure of the inner wall of the pipe.

[0041] In this embodiment, the supporting and bearing assembly also includes an assembly stand plate 140 and an assembly suspension 150. A pair of assembly stands are provided, each located on the outer side of the heat sink body and joined to the support bands. Both ends of the assembly suspension are engaged with the assembly stands, allowing the entire lighting fixture to be assembled. The assembly stands have deflection core holes and positioning core holes. Both ends of the assembly suspension are engaged with the deflection core holes via bearing pins 151, allowing deflection around the deflection core holes. A set of positioning core holes is provided, each arranged along an arc-shaped path centered on the deflection core holes. The assembly suspension is engaged with the positioning core holes via locking bolts, which position the deflection angle of the assembly suspension to meet different installation requirements.

[0042] This lighting fixture efficiently conducts and dissipates heat generated by the lamp head through a dual-path system. First, heat is absorbed by the mounting base via direct conduction and diffused to the connected multi-layer heat sink. Simultaneously, a heat pipe, a key active heat dissipation component, is closely attached to the light-emitting end. Its internal working fluid absorbs heat and evaporates, releasing latent heat and condensing at the cold end embedded in the heat sink. The liquid then flows back through capillary action, creating a cycle that efficiently transfers heat from the heat source to the radiator over long distances. Subsequently, heat diffuses across the multi-layer heat sink, which has a large surface area. The serrated grooves at the edges of the plates further increase the heat dissipation area. To enhance heat dissipation, insulating strips ensure unobstructed flow, creating stable heat dissipation gaps between adjacent heat sinks. Orifices promote airflow and temperature equilibrium between the layers, utilizing air convection and thermal radiation to rapidly dissipate heat into the surrounding environment, ensuring stable operation and a long lifespan for the lighting fixture.
