Description

Technical Field

[0001] This utility model relates to the field of LED street light technology, and in particular to a high-power integrated LED street light with a heat dissipation structure. Background Technology

[0002] In urban road nighttime lighting, high-power integrated LED streetlights with optimized heat dissipation structures are typically required.

[0003] Existing high-power integrated LED streetlights with heat dissipation structures have significant deficiencies in heat dissipation. They employ an embedded, continuous cooling fan design, which automatically runs continuously as long as the light is turned on, leading to energy waste and a shortened fan lifespan. At the same time, when the light source is in operation at night, a large number of mosquitoes and insects are attracted to the surface of the lamp body and must be cleaned manually periodically. This dual design defect not only increases maintenance costs but may also affect the lifespan of the LEDs due to reduced heat dissipation efficiency or reduce luminous efficacy due to the accumulation of insect carcasses, ultimately affecting the normal performance and lighting effect of the streetlight.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a high-power integrated LED street light with a heat dissipation structure. The high-power integrated LED street light with a heat dissipation structure includes a support component 1 and an auxiliary component 2.

[0030] Through the coordinated operation of support component 1 and auxiliary component 2, heat dissipation efficiency and ease of maintenance are significantly improved, effectively solving the problems of energy waste and insect attachment. This ensures the optimal operating temperature of the LED chip and avoids light efficiency degradation caused by insect carcasses. At the same time, it integrates intelligent temperature control heat dissipation with maintenance-free cleaning, greatly reducing energy consumption and extending the service life of the street light.

[0031] Specifically, the support component 1 includes a street light pole 11, with a street light base 12 fixed to the bottom of the street light pole 11 by bolts, and a street light connector 13 fixed to one side of the street light pole 11 by bolts.

[0032] Specifically, the auxiliary component 2 is located on one side of the support component 1 and includes an illumination component 21 that is fixed to one side of the street light connector 13 by bolts. A heat sink 22 is movably connected to the top of the illumination component 21, and a heat-sensitive electrical component 23 is fixed to the inner wall of the illumination component 21 by bolts.

[0033] Example 2

[0034] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the street light connector 13 includes a street light connector rod 13-1 that is fixed to one side of the street light pole 11 by bolts, and a street light reinforcing rib 13-2 that is fixed to the bottom of the street light connector rod 13-1 by bolts. The street light reinforcing rib 13-2 is fixed to one side of the street light pole 11 by bolts.

[0036] By setting the street light connecting rod 13-1, the lighting component 21 can be securely connected to the street light pole 11, ensuring that the lighting component 21 will not loosen or shift during long-term use.

[0037] Specifically, the lighting component 21 includes a first housing 21-1 that is fixed to one side of the street light connecting rod 13-1 by bolts, an installation guide rail 21-2 that is fixed to the inner wall of the first housing 21-1 by bolts, and a street light body 21-3 that is fixed to the bottom of the first housing 21-1 by bolts.

[0038] The first housing 21-1 provides a protective space for the LED street light body 21-3 and its internal components, effectively preventing rainwater, dust and other external debris from entering, protecting the internal circuits and light source, and extending service life.

[0039] Specifically, the heat sink 22 includes a third housing 22-2 movably connected to the top of the first housing 21-1. The bottom of the third housing 22-2 is fixed with a guide block 22-4 that mates with the mounting rail 21-2 by bolts. A sealing gasket 22-5 is attached to the bottom of the third housing 22-2.

[0040] The third housing 22-2 serves as the main heat dissipation carrier. Its special heat dissipation hole layout can quickly dissipate the heat generated by the LED street light body 21-3 to the outside, effectively reducing the operating temperature of the LED light source, preventing light decay due to overheating, and ensuring the stability of lighting brightness.

[0041] Specifically, the top of the third housing 22-2 is fixed to the second housing 22-1 by bolts, and the bottom of the second housing 22-1 is fitted with an axial flow fan 22-3.

[0042] The second housing 22-1 provides installation space for the axial flow fan 22-3. Its reasonable structural design helps to guide airflow, optimize heat dissipation path, and improve overall heat dissipation effect.

[0043] Specifically, an embedded waterproof ventilation filter 22-6 is installed on one side of the second housing 22-1.

[0044] By setting the embedded waterproof ventilation filter 22-6, while ensuring smooth airflow inside the second housing 22-1, it effectively blocks debris from entering and prevents leaves, insects, etc. from clogging the ventilation opening and affecting the heat dissipation effect.

[0045] Specifically, the thermally conductive component 23 includes a thermally conductive metal pad 23-3 embedded in the bottom of the first housing 21-1. A metal connecting block 23-2 is fixed to the top of the thermally conductive metal pad 23-3 by bolts, and a bimetallic strip 23-1 is fixed to one side of the metal connecting block 23-2 by bolts.

[0046] By setting the thermally conductive metal pad 23-3, the heat generated by the LED street light body 21-3 can be quickly conducted to the bimetallic strip 23-1, providing timely and accurate temperature signals for thermal control.

[0047] Specifically, the inner wall of the first housing 21-1 is fixed with a fixed vertical plate 23-4 by bolts, and a sliding rod 23-5 is slidably connected to the inner wall of the fixed vertical plate 23-4. A return spring 23-9 is sleeved on the surface of the sliding rod 23-5.

[0048] Specifically, a first electrode plate 23-8 is fixed to one side of the sliding rod 23-5 by bolts, a second electrode plate 23-7 is provided on one side of the first electrode plate 23-8, and a power cable 21-4 is fixed to one side of the second electrode plate 23-7 by bolts.

[0049] Specifically, a mounting block 23-6 is fixed to one side of the second electrode plate 23-7 by bolts, and the mounting block 23-6 is fixed to the inner wall of the first housing 21-1 by bolts.

[0050] When in use, the LED street light body 21-3 lights up and begins to heat up. The heat is transferred sequentially through the thermally conductive metal pad 23-3 and the metal connecting block 23-2 to the bimetallic strip 23-1. When the temperature rises to the preset threshold, the bimetallic strip 23-1 bends and deforms due to the difference in thermal expansion coefficients, pushing the sliding rod 23-5 to slide along the fixed vertical plate 23-4 and compressing the return spring 23-9. This causes the first electrode 23-8 to contact the second electrode 23-7, making the circuit conductive. The current then drives the axial flow fan 22-3 to start rotating through the power cable 21-4.

[0051] After the axial flow fan 22-3 rotates, on the one hand, the airflow flows through the top of the first housing 21-1 and carries away the heat generated by the LED light source and internal circuit, thus achieving the heat dissipation function. On the other hand, the downward-blown air forms an airflow barrier around the street light, driving away mosquitoes attracted by the light.

[0052] When the equipment needs to be disassembled and repaired, first unplug the power cable 21-4, then push the heat sink 22 to one side so that the guide block 22-4 at the bottom of the third housing 22-2 slides and separates from the mounting rail 21-2 on the inner wall of the first housing 21-1. This completes the disassembly of the heat sink 22, making it convenient to repair internal components such as the heat-sensitive power-conducting component 23. The entire device achieves heat dissipation, mosquito repellency, and convenient maintenance functions through the above principle.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
