Technical Problem

现有技术中,投光灯多采用密集排列的鳍片作为散热结构,鳍片呈向外突出的片状,其迎风面大、整体风阻显著,在户外多风环境尤其是强风天气下,鳍片易受到持续且较大的风力冲击,不仅会导致鳍片自身发生变形、弯折甚至断裂,影响鳍片散热功能的正常发挥,还会因风阻产生的侧向作用力带动投光灯整体晃动,影响投光灯与安装面的连接稳定性,长期使用易造成投光灯上的固定结构松动、老化,严重时可能引发投光灯脱落的安全隐患,进而导致投光灯无法满足户外复杂风环境下长期稳定使用的需求

Benefits of technology

灯体工作时产生的热量传递至壳体,与壳体连接且呈矩形分布的多根散热管将壳体内的热量导出,并通过散热管的管壁与周围空气进行热交换,最终实现热量的快速散发,起到散热效果。由于散热管的截面形状为圆形,相较于现有技术中的片状鳍片,散热管的圆形表面无明显棱角,当气流接触散热管时会沿着散热管的弧形表面顺畅流过,减少了气流在散热管表面的分离和涡流产生;另一方面,多根散热管呈矩形分布,相比密集排列的鳍片大幅降低了迎风面的整体阻碍面积,进而显著降低了风阻,低风阻使得户外多风环境尤其是强风天气下,散热管受到的风力冲击大幅减小,不仅可避免散热管发生变形、弯折甚至断裂,保障散热功能持续稳定发挥,还能减弱风阻产生的侧向作用力,减少投光灯整体晃动,提升投光灯与安装面的连接稳定性,避免固定结构因长期晃动而松动、老化,有效规避投光灯脱落的安全隐患,最终满足投光灯在户外复杂风环境下长期稳定使用的需求。

Description

Technical Field

[0001] This utility model relates to lighting technology, and in particular to a low wind resistance floodlight. Background Technology

[0002] Floodlights are outdoor lighting fixtures with directional illumination, concentrated light, high intensity, and wide coverage. They are widely used in large-area mining areas, stadiums, overpasses, monuments, parks, flower beds, and other outdoor locations. To ensure the effectiveness and lifespan of floodlights, they typically incorporate a heat dissipation structure. In existing technologies, floodlights often use densely arranged fins as their heat dissipation structure. These fins are outward-protruding plates with a large windward surface and significant overall wind resistance. In windy outdoor environments, especially in strong winds, the fins are easily subjected to continuous and strong wind impacts. This can cause the fins to deform, bend, or even break, affecting their heat dissipation function. Furthermore, the lateral force generated by wind resistance can cause the entire floodlight to sway, affecting the stability of the connection between the floodlight and the mounting surface. Long-term use can lead to loosening and aging of the fixing structure on the floodlight, potentially causing it to detach and posing a safety hazard. Ultimately, this results in the floodlight failing to meet the requirements for long-term stable use in complex outdoor wind environments. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a low-wind-resistance floodlight that can meet the needs of long-term stable use in complex outdoor wind environments.

[0004] The low-drag floodlight according to an embodiment of the present invention includes a housing; a lamp body disposed within the housing; and multiple heat dissipation pipes, one end of each of the multiple heat dissipation pipes being connected to the housing, the multiple heat dissipation pipes being rectangularly distributed, and the cross-sectional shape of each heat dissipation pipe being circular.

[0005] It has at least the following beneficial effects: The heat generated when the lamp body is working is transferred to the housing. Multiple heat dissipation pipes connected to the housing and distributed in a rectangular pattern conduct the heat out of the housing and exchange heat with the surrounding air through the pipe walls, thus achieving rapid heat dissipation and heat dissipation effect. Because the heat dissipation pipe has a circular cross-sectional shape, compared to the sheet-like fins in existing technology, the circular surface of the heat dissipation pipe has no obvious sharp edges. When the airflow comes into contact with the heat dissipation pipe, it will flow smoothly along the arc surface of the heat dissipation pipe, reducing the separation of airflow and the generation of eddies on the surface of the heat dissipation pipe. On the other hand, the multiple heat dissipation pipes are distributed in a rectangular shape, which significantly reduces the overall obstruction area of ​​the windward side compared to the densely arranged fins, thereby significantly reducing wind resistance. The low wind resistance greatly reduces the wind impact on the heat dissipation pipes in windy outdoor environments, especially in strong winds. This not only prevents the heat dissipation pipes from deforming, bending, or even breaking, ensuring the continuous and stable performance of the heat dissipation function, but also reduces the lateral force generated by wind resistance, reduces the overall swaying of the floodlight, improves the connection stability between the floodlight and the mounting surface, and prevents the fixed structure from loosening and aging due to long-term swaying. This effectively avoids the safety hazard of the floodlight falling off, and ultimately meets the needs of the floodlight for long-term stable use in complex outdoor wind environments.

[0006] According to an embodiment of the present utility model, the low wind resistance floodlight includes a lamp plate, a light-transmitting panel, and an anti-glare honeycomb panel. The lamp plate, the light-transmitting panel, and the anti-glare honeycomb panel are all disposed within the housing, and the anti-glare honeycomb panel is disposed between the lamp plate and the light-transmitting panel.

[0007] According to the low wind resistance floodlight of this utility model embodiment, the lamp body further includes a heat dissipation plate, which is disposed inside the housing and connected to the lamp plate on the side facing the plurality of heat dissipation pipes.

[0008] The low-drag floodlight according to an embodiment of the present invention also includes a bracket, and the housing is disposed on the bracket.

[0009] According to an embodiment of the present invention, in a low-drag floodlight, the housing is rotatably connected to the bracket so that the illumination angle of the lamp body can be adjusted.

[0010] According to the low wind resistance floodlight of this utility model embodiment, the bracket is provided with an arc-shaped guide hole, the housing is provided with a first stud, the first stud is inserted into the arc-shaped guide hole, and a first nut is threadedly connected to the first stud. The first nut can press on the bracket so that the housing is fixed on the bracket.

[0011] The low-drag floodlight according to an embodiment of the present invention also includes a reinforcing frame, which is connected to the other end of the plurality of heat dissipation pipes.

[0012] According to the low wind resistance floodlight of this utility model embodiment, the reinforcing frame is provided with two arc-shaped guide plates, and multiple heat dissipation pipes are disposed between the two arc-shaped guide plates, with the two arc-shaped guide plates protruding in opposite directions.

[0013] According to the low wind resistance floodlight of this utility model embodiment, both of the arc-shaped guide plates are rotatably connected to the reinforcing frame.

[0014] According to an embodiment of the low-drag floodlight of this utility model, each of the two arc-shaped guide plates is provided with mounting holes. The reinforcing frame is provided with two second studs, each passing through one of the two mounting holes. Each of the two second studs is threaded with a second nut, which can press against the two arc-shaped guide plates to fix them to the reinforcing frame. Additional aspects and advantages of this utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.

Detailed Implementation

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] refer to Figures 1 to 3 This utility model discloses a low wind resistance floodlight, including a housing 100, a lamp body 200, and multiple heat dissipation pipes 110. The lamp body 200 is disposed inside the housing 100; one end of each of the multiple heat dissipation pipes 110 is connected to the housing 100, the multiple heat dissipation pipes 110 are arranged in a rectangular shape, and the cross-sectional shape of the heat dissipation pipes 110 is circular.

[0020] It is understandable that the heat generated when the lamp body 200 is working is transferred to the housing 100. Multiple heat dissipation pipes 110 connected to the housing 100 and distributed in a rectangular shape conduct the heat out of the housing 100 and exchange heat with the surrounding air through the pipe wall of the heat dissipation pipes 110, thus achieving rapid heat dissipation and heat dissipation effect. Because the heat dissipation pipe 110 has a circular cross-sectional shape, compared with the sheet-like fins in the prior art, the circular surface of the heat dissipation pipe 110 has no obvious sharp edges. When the airflow comes into contact with the heat dissipation pipe 110, it will flow smoothly along the arc surface of the heat dissipation pipe 110, reducing the separation of airflow and the generation of eddies on the surface of the heat dissipation pipe 110. On the other hand, the multiple heat dissipation pipes 110 are distributed in a rectangular shape, which significantly reduces the overall obstruction area of ​​the windward side compared with the densely arranged fins, thereby significantly reducing wind resistance. The low wind resistance greatly reduces the wind impact on the heat dissipation pipe 110 in windy outdoor environments, especially in strong winds. This not only prevents the heat dissipation pipe 110 from deforming, bending or even breaking, ensuring the continuous and stable performance of the heat dissipation function, but also reduces the lateral force generated by wind resistance, reduces the overall swaying of the floodlight, improves the connection stability between the floodlight and the mounting surface, avoids the fixed structure from loosening and aging due to long-term swaying, effectively avoids the safety hazard of the floodlight falling off, and ultimately meets the needs of the floodlight for long-term stable use in complex outdoor wind environments.

[0021] refer to Figure 3 , the lamp body 200 comprises a light board 210, a light-transmitting panel 220 and an anti-glare honeycomb panel 230, wherein the light board 210, the light-transmitting panel 220 and the anti-glare honeycomb panel 230 are all arranged in the housing 100, and the anti-glare honeycomb panel 230 is arranged between the light board 210 and the light-transmitting panel 220. In the present utility model, the light board 210 is a conventional LED light board 210, which is mainly used for providing a light source; the light-transmitting panel 220 is a transparent plate mounted in front of the anti-glare honeycomb panel 230, has good light transmittance, and can allow the light emitted by the light board 210 to uniformly pass through and be softened by the light-transmitting panel 220; the anti-glare honeycomb panel 230 is an optical element arranged between the light board 210 and the light-transmitting panel 220, and is composed of a plurality of hexagonal or circular honeycomb units, which is mainly used for reducing the glare phenomenon. The light emitted by the light board 210 firstly passes through the anti-glare honeycomb panel 230, the honeycomb structure constrains the light within a specific angle range, reduces stray light scattered to the side to lower glare, so that the light is concentrated and projected forward, then the light passes through the light-transmitting panel 220, and the light-transmitting panel 220 further uniformly diffuses the light, so that the finally projected light spot is softer and more uniform. The light board 210, the light-transmitting panel 220 and the anti-glare honeycomb panel 230 are all conventional arrangements in the field of lamps, and will not be further described herein.

[0022] In the present utility model, the lamp body 200 further comprises a vapor chamber, the vapor chamber is arranged in the housing 100, and the vapor chamber is connected to a side of the light board 210 facing the plurality of heat dissipation pipes 110. In the present utility model, the vapor chamber is a plate-shaped heat transfer element with working medium encapsulated inside and realizing efficient heat transfer depending on phase change of the working medium, and a capillary structure is arranged inside the vapor chamber, which can quickly diffuse local heat to the entire plate surface. It can be understood that the vapor chamber is connected to the side of the light board 210 facing the heat dissipation pipes 110, the vapor chamber can quickly absorb heat generated when the light board 210 works and uniformly conduct the heat to the entire plate surface of the vapor chamber, so as to prevent the light board 210 from overheating caused by local heat accumulation; on the other hand, the vapor chamber can enable heat to be transferred to the housing 100 and the heat dissipation pipes 110 more evenly, ensures stable temperature in each area of the light board 210, and thereby facilitates improvement of the lighting stability and reliability of the floodlight. The vapor chamber is a conventional heat dissipation element, and will not be further described herein.

[0023] Refer Figure 2 , the low wind resistance floodlight further comprises a bracket 300, and the housing 100 is arranged on the bracket 300. It can be understood that the housing 100 is mounted on a mounting surface (such as a wall surface, a ground surface, etc.) through the bracket 300, and the arrangement of the bracket 300 can realize flexible mounting and stable fixing of the floodlight, improve the structural stability of the whole floodlight after mounting, and prevent the housing 100 from shifting caused by vibration or wind action in an outdoor environment. Reference Figure 2The housing 100 is rotatably connected to the bracket 300 so that the illumination angle of the lamp body 200 can be adjusted. The bracket 300 is provided with an arc-shaped guide hole 310, and the housing 100 is provided with a first stud 320. The first stud 320 passes through the arc-shaped guide hole 310, and a first nut 330 is threadedly connected to the first stud 320. The first nut 330 can press against the bracket 300 so that the housing 100 is fixed on the bracket 300. Understandably, when adjusting the illumination angle of the lamp body 200, the operator first loosens the first nut 330 on the first stud 320, creating a gap between the first nut 330 and the bracket 300, thereby releasing the first nut 330 from its fixed constraint on the housing 100. Then, the operator pushes the housing 100 to rotate, at which point the first stud 320 slides along the arc-shaped guide hole 310 on the bracket 300. After the housing 100 drives the lamp body 200 to the target illumination angle, the operator tightens the first nut 330, pressing it tightly against the bracket 300. The friction between the first nut 330 and the bracket 300 locks the position of the first stud 320, thus fixing the housing 100 and completing the adjustment and fixing of the illumination angle of the lamp body 200. In this invention, the housing 100 is hinged to the bracket 300 via a hinge shaft, and the arc-shaped guide hole 310 extends with the axis of the hinge shaft as its center.

[0024] As another embodiment of this utility model, refer to Figure 4 The low-wind-resistance floodlight also includes a reinforcing frame 120, which is connected to the other ends of multiple heat dissipation pipes 110. It is understood that by connecting the reinforcing frame 120 to the other ends of the multiple heat dissipation pipes 110, the reinforcing frame 120 integrates the dispersed heat dissipation pipes 110 into a stable overall structure. This not only improves the wind load resistance of the heat dissipation pipes 110, preventing them from deforming, bending, or even breaking due to excessive individual stress in strong outdoor winds, but also ensures the stable performance of the heat dissipation function of the heat dissipation pipes 110. In this invention, the reinforcing frame 120 includes a frame and a perforated plate. The perforated plate is connected to the frame, and the other ends of the multiple heat dissipation pipes 110 all pass through holes in the perforated plate and are connected to the perforated plate.

[0025] As another embodiment of this utility model, refer to Figure 5 and Figure 6The reinforcement frame 120 is provided with two arc-shaped guide plates 130, and multiple heat dissipation pipes 110 are located between the two arc-shaped guide plates 130. The two arc-shaped guide plates 130 protrude in opposite directions. It is understandable that a flow channel for airflow is formed between the two arc-shaped guide plates 130. The arc-shaped structure of the two arc-shaped guide plates 130 can guide the airflow to flow smoothly along the curved surface of the arc-shaped guide plates 130, avoiding the airflow from directly impacting the heat sink 110 and forming violent turbulence. On the other hand, when the outdoor airflow comes into contact with the arc-shaped guide plates 130, the airflow will be guided by the arc-shaped surface of the arc-shaped guide plates 130 and concentrated towards the area where the heat sink 110 is located, avoiding the airflow from being dispersed and lost to both sides of the area where the heat sink 110 is located due to lack of guidance. Moreover, the arc-shaped guide plates 130 can reduce the airflow resistance, allowing the airflow to pass through the gap between the heat sink 110 more smoothly. This not only greatly increases the total amount of airflow actually acting on the wall of the heat sink 110, but also allows the airflow to cover the surface of the heat sink 110 more evenly, reducing the dead air angles around the heat sink 110, accelerating the heat exchange rate between the heat sink 110 and the air, and thus improving the heat dissipation effect of the heat sink 110.

[0026] refer to Figure 5 Both arc-shaped air deflectors 130 are rotatably connected to the reinforcing frame 120. It is understood that both arc-shaped air deflectors 130 can rotate, allowing operators to adjust the orientation of the flow channels between them according to the actual outdoor wind direction. This ensures the flow channels between the two arc-shaped air deflectors 130 are always aligned with the airflow direction, enabling the two arc-shaped air deflectors 130 to more accurately guide and converge the dispersed airflow to the area where the heat dissipation pipe 110 is located. This avoids the problem of airflow deviating from the heat dissipation pipe 110 due to changes in wind direction, preventing it from fully utilizing the heat dissipation pipe 110. Furthermore, rotating the arc-shaped air deflectors 130 optimizes the airflow path through the gaps in the heat dissipation pipe 110, reducing airflow resistance while maximizing the total amount of airflow acting on the surface of the heat dissipation pipe 110. This ensures that the heat dissipation pipe 110 can always achieve efficient heat exchange through sufficient airflow in complex and variable outdoor wind environments, thereby improving the heat dissipation effect of the heat dissipation pipe 110.

[0027] refer to Figure 5Each of the two arc-shaped guide plates 130 has a mounting hole, and the reinforcing frame 120 has two second studs 140. The two second studs 140 are respectively inserted into the two mounting holes, and each of the two second studs 140 is threaded with a second nut 150. The two second nuts 150 can press on the two arc-shaped guide plates 130 respectively, so that the two arc-shaped guide plates 130 are fixed on the reinforcing frame 120. Understandably, when it is necessary to rotate the two arc-shaped guide vanes 130, the operator first loosens the second nuts 150 on the two second studs 140 respectively, so that a gap is created between the two second nuts 150 and the corresponding arc-shaped guide vanes 130, thereby releasing the clamping and fixing constraint of the second nuts 150 on the arc-shaped guide vanes 130; then, according to the actual outdoor wind direction requirements, the operator pushes the two arc-shaped guide vanes 130 to rotate around the corresponding second studs 140 respectively; after completing the adjustment of the two arc-shaped guide vanes 130, the operator tightens the two second nuts 150, so that the two second nuts 150 press against the two arc-shaped guide vanes 130 respectively, and locks the position of the arc-shaped guide vanes 130 through the friction between the second nuts 150 and the arc-shaped guide vanes 130, thereby firmly fixing the two arc-shaped guide vanes 130 on the reinforcement frame 120, thus completing the adjustment and fixing of the arc-shaped guide vanes 130.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
