Description

Technical Field

[0001] This utility model relates to the field of detection light source technology, and in particular to a dustproof and waterproof outdoor air-cooled surface light source. Background Technology

[0002] Traditional high-brightness, high-power surface light sources typically employ either air cooling or water cooling. However, air cooling systems often significantly increase the overall size and thickness of the equipment, placing greater demands on installation space. Furthermore, air cooling has limitations in environmental adaptability, especially in outdoor use where fans are susceptible to dust, humidity, and other environmental factors, posing a serious challenge to fan reliability and lifespan. On the other hand, while water cooling is more efficient, its water-cooling plates have complex manufacturing processes and high production costs, and it requires the use of expensive water chillers, significantly increasing system complexity and overall cost. Moreover, traditional air cooling technology has a fundamental limitation: it is generally only effective for linear light source structures with a single, narrow airflow channel, and cannot meet the heat dissipation requirements of surface light sources with large heat-generating surfaces. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a dustproof and waterproof outdoor air-cooled surface light source. This invention has more flexible application scenarios, lower processing costs, and solves the problem that large-volume surface lights cannot use air cooling for heat dissipation.

[0004] To achieve the above objectives, this utility model provides a dustproof and waterproof outdoor air-cooled surface light source, comprising:

[0005] The main housing forms a first optical path cavity within it;

[0006] An LED circuit board is disposed on the upper end of the main housing, and the LED circuit board is provided with LED beads, which are placed in the first optical path cavity;

[0007] A diffuser plate is disposed at the upper end of the main housing, and the diffuser plate covers the upper part of the first optical path cavity;

[0008] The heat dissipation assembly includes a heat dissipation support and a heat dissipation nozzle. The heat dissipation support is detachably connected to the lower end of the main housing and abuts against the LED circuit board, forming a sealed heat dissipation cavity inside the heat dissipation support. Several heat dissipation columns are provided on the inner wall of the heat dissipation support and placed inside the heat dissipation cavity. The heat dissipation support is provided with a heat dissipation air inlet and a heat dissipation air outlet communicating with the heat dissipation cavity. The heat dissipation air inlet is connected to a heat dissipation air source.

[0009] Furthermore, the main housing is a frame structure with openings at both the top and bottom, the internal space of the main housing is the first optical path cavity, and a first stepped mounting groove is provided at the lower end of the main housing, on which the LED circuit board is snapped.

[0010] Furthermore, a first mounting hole is provided at the upper end of the main housing, and a second mounting hole matching the first mounting hole is provided on the diffuser plate.

[0011] Furthermore, a second mounting groove is provided at the upper end of the main housing, and a first sealing member is engaged in the second mounting groove. The height of the first sealing member is slightly greater than the depth of the second mounting groove, so that the first sealing member is in close contact with the diffuser plate.

[0012] Furthermore, a heat dissipation base plate is provided at the lower end of the heat dissipation support, and the heat dissipation base plate is detachably connected to the heat dissipation support.

[0013] Furthermore, a third mounting groove is provided on the heat dissipation support, and a second sealing element is engaged in the third mounting groove. The height of the second sealing element is slightly greater than the depth of the third mounting groove, so that the second sealing element abuts tightly against the heat dissipation base plate.

[0014] Furthermore, the heat dissipation columns are evenly distributed within the heat dissipation cavity and are integrally formed with the heat dissipation support.

[0015] Furthermore, the heat dissipation column has a long strip structure, and a horizontal air duct is formed between adjacent heat dissipation columns.

[0016] Furthermore, the heat dissipation column is a columnar structure, and the heat dissipation columns are distributed in an array within the heat dissipation cavity. A transverse air duct is formed between two adjacent heat dissipation columns arranged horizontally, and a longitudinal air duct is formed between two adjacent heat dissipation columns arranged vertically.

[0017] Furthermore, an airflow guide plate is provided inside the heat dissipation cavity. The airflow guide plate is located between the heat dissipation column and the heat dissipation air inlet, and a number of air guide holes are provided on the airflow guide plate.

[0018] Furthermore, it also includes an air intake nozzle, which has an L-shaped structure. The heat dissipation air inlet is disposed on the heat dissipation base plate. One end of the air intake nozzle is connected to an external air source, and the other end of the air intake nozzle is connected to the heat dissipation air inlet.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a heat dissipation cavity on a heat dissipation support and an integrally formed heat dissipation column, significantly increasing the heat dissipation area. An airflow guide plate is added between the heat dissipation inlet and the heat dissipation column. The guide plate has multiple airflow holes, which guide the heat dissipation airflow from the heat dissipation inlet into the heat dissipation cavity. The airflow is guided by the airflow guide plate to achieve uniform pressure and flow, forming multiple uniform airflows that enter the air duct between the heat dissipation columns for heat exchange, achieving a more efficient and uniform heat dissipation effect. After the airflow passes through the heat dissipation column for heat exchange, the airflow that has absorbed heat is finally discharged from the heat dissipation outlet. Furthermore, the air intake nozzle connects from the bottom of the heat dissipation base plate. Therefore, when a strong external airflow enters the front end of the airflow guide plate, the airflow will first rush towards the top surface inside the heat dissipation support, and then enter the heat dissipation cavity through the airflow guide plate. This allows the gas to enter the heat dissipation cavity more evenly, resulting in more uniform heat dissipation. The heat dissipation support adopts a combination design of heat dissipation cavity and base plate, which simplifies the manufacturing process and reduces costs. The heat dissipation base plate and heat dissipation cavity are fixed in a detachable manner using a second sealing element and screws to prevent air leakage that could lead to insufficient internal heat dissipation pressure. For outdoor waterproof and dustproof requirements, this air-cooled heat dissipation solution is more practical and easier to maintain than air cooling, eliminating the need to consider the impact of water and dust on the fan. Compared to water cooling, it is lower in cost, requiring only one main air cooling pipe connection. Exhaust gas is directly discharged without recycling and will not harm the environment. This invention is not limited by the shape of the equipment, is simple to manufacture, and can even be applied to large-size surface light sources. Attached Figure Description

[0032] The technology of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0035] like Figures 1 to 8 This invention discloses a dustproof and waterproof outdoor air-cooled surface light source, comprising a main housing 1, an LED circuit board 2, a diffuser plate 3, and a heat dissipation assembly 4. The LED circuit board 2 is equipped with LED beads, and the heat dissipation assembly 4 includes a heat dissipation support 41 and a heat dissipation nozzle 42.

[0036] like Figures 1 to 4 As shown, a first optical path cavity 11 is formed within the main housing 1. In this embodiment, the main housing 1 is a frame structure with openings at both the top and bottom. The internal space in the middle of the main housing 1 is the aforementioned first optical path cavity 11. A first mounting hole 12 is provided at the upper end of the main housing 1, and a second mounting hole 31 matching the first mounting hole 12 is provided on the diffuser plate 3. The diffuser plate 3 is relatively fixed to the upper end of the main housing 1 through the second mounting hole 31 and the first mounting hole 12 with screws, thereby covering the upper part of the first optical path cavity 11, making the first optical path cavity 11 a closed optical space, effectively preventing external dust from entering and affecting the light output quality. At the same time, a second mounting groove 13 is provided at the upper end of the main housing 1, and a first sealing member 5 is engaged in the second mounting groove 13. The height of the first sealing member 5 is slightly greater than the depth of the second mounting groove 13, so that the first sealing member 5 and the diffuser plate 3 are in close contact. The first sealing member 5 is a sealing ring made of silicone material, which can effectively improve the waterproof and dustproof performance of the main housing 1 and ensure stable operation in complex outdoor environments.

[0037] A first stepped mounting groove 14 is provided at the lower end of the main housing 1. The LED circuit board 2 is snapped into the first stepped mounting groove 14, so that the LED lamp bead is placed in the first light path cavity 11, facing the diffuser plate 3 above, thereby realizing that the light passes through the first light path cavity 11 and is uniformly diffused and efficiently output by the diffuser plate 3.

[0038] After the LED circuit board 2 is installed in the first stepped mounting slot 14, the main housing 1 and the upper end of the heat sink support 41 are directly fixed together by screws. At this time, the back of the LED circuit board 2 is tightly attached to the top of the heat sink support 41. The heat sink support 41 of this utility model can be made of thermally conductive materials, such as aluminum, copper, copper alloy, aluminum alloy and other materials with good thermal conductivity, so as to better absorb the heat of the LED circuit board 2.

[0039] like Figure 2 and Figure 5As shown, a sealed heat dissipation cavity 411 is formed within the heat dissipation support 41. An opening communicating with the heat dissipation cavity 411 is formed at the lower end of the heat dissipation support 41. In this embodiment, a heat dissipation base plate 43 is provided at the lower end of the heat dissipation support 41 to seal the aforementioned heat dissipation cavity 411. The heat dissipation base plate 43 and the heat dissipation support 41 are detachably connected by screws, facilitating later maintenance and cleaning. A third mounting groove 412 is provided on the heat dissipation support 41, and a second sealing member 6 is engaged within the third mounting groove 412. The height of the second sealing member 6 is slightly greater than the depth of the third mounting groove 412, ensuring a tight abutment between the second sealing member 6 and the heat dissipation base plate 43. The second sealing member 6 is also a sealing ring made of silicone material, ensuring the sealing performance of the heat dissipation cavity 411, effectively preventing moisture and dust from entering the cavity, and further improving the product's protection level.

[0040] A plurality of heat dissipation columns 413 are provided on the inner wall of the heat dissipation support 41 and placed inside the heat dissipation cavity 411. The heat dissipation columns 413 are evenly distributed in the heat dissipation cavity 411 and are integrally formed with the heat dissipation support 41. The heat dissipation columns 413 protrude outward from the inner wall of the heat dissipation support 41, effectively increasing the heat dissipation contact area and improving the heat conduction efficiency. A first region 416 is formed on one side of the heat dissipation cavity 411. The first region 416 is adjacent to the heat dissipation columns 413. An airflow guide plate 7 is provided on the first region 416. The airflow guide plate 7 is disposed between the heat dissipation columns 413 and the heat dissipation air inlet 431. A plurality of air guide holes 71 are provided on the airflow guide plate 7, such as... Figure 8 The airflow guide section shown has connecting parts 72 at both ends. By engaging and fixing the connecting parts 72 at both ends of the airflow guide section with the inner wall of the heat dissipation support 41, the airflow guide plate 7 is stably positioned between the heat dissipation inlet 431 and the heat dissipation column 413. Alternatively, screw holes can be provided on the connecting parts 72 for screw tightening to enhance the connection and ensure the airflow guide plate 7 remains stable under long-term vibration. An arc-shaped guide part 73 is provided on the inner side of the connecting parts 72. This guide part 73 has an arc structure and can effectively guide airflow into the air guide hole 71, allowing air to flow evenly along the surface of the heat dissipation column 413 and improving convection heat dissipation efficiency. Meanwhile, at least two rows of air guide holes 71 are provided on the airflow guide section, and each row of air guide holes 71 is staggered to enhance airflow disturbance, break the boundary layer thermal resistance, and further improve heat dissipation efficiency. Furthermore, the diameter of the air guide holes 71 gradually increases from the air inlet side to the air outlet side, in accordance with the airflow expansion characteristics, reducing flow resistance, optimizing the air duct design, and ensuring that heat can be continuously and efficiently discharged from the heat dissipation cavity 411, thus ensuring the stability and reliability of the LED module under long-term operation.

[0041] In this embodiment, the heat dissipation columns 413 are arranged in an array within the heat dissipation cavity 411, such as... Figure 5As shown, the lateral side of the heat dissipation support 41 is in the lateral direction A, and the longitudinal side of the heat dissipation support 41 is in the longitudinal direction B. A lateral air duct 414 is formed between two adjacent heat dissipation columns 413. The lateral air duct 414 is parallel to the lateral side of the heat dissipation support 41. In this embodiment, the heat dissipation columns 413 can be set into columns of various shapes to increase the contact area with the airflow and improve the heat dissipation effect. In this embodiment, the heat dissipation columns 413 are columnar structures and are arranged in an array in the heat dissipation cavity 411. A lateral air duct 414 is formed between two adjacent heat dissipation columns 413 arranged laterally, and a longitudinal air duct 415 is formed between two adjacent heat dissipation columns 413 arranged longitudinally. The lateral air duct 414 and the longitudinal air duct 415 are interconnected to form a three-dimensional ventilation network, which enables the airflow to flow in multiple directions in the heat dissipation cavity 411, effectively breaking the airflow dead zone and improving the overall heat dissipation uniformity. The staggered distribution of the air vents 71 and the gradual change in vent diameter work together to further enhance airflow disturbance and penetration capabilities, allowing cooling air to fully contact the surface of each heat dissipation column 413, thus significantly improving the heat dissipation effect.

[0042] Of course, the density and height of the heat sink column 413 can also be adjusted according to the actual heat dissipation requirements to adapt to the thermal load characteristics of LED modules with different power, maximize heat dissipation efficiency while ensuring structural strength, and improve the working stability and lifespan of the product in high-temperature environments.

[0043] In some implementations, such as Figure 6 As shown, the heat dissipation column 413 has an overall elongated structure that extends laterally. A transverse airflow channel 414 is formed between two adjacent elongated heat dissipation columns 413, which facilitates the airflow to pass laterally through the heat dissipation cavity 411. This elongated structure can be selected according to requirements and also has good heat dissipation performance.

[0044] like Figure 5 As shown, a heat dissipation outlet 417 is provided on the heat dissipation support 41, and a heat dissipation inlet 431 and a heat dissipation outlet 417 are respectively located at the front and rear ends of the heat dissipation cavity 411. The heat dissipation outlet 417 is located on one side wall of the heat dissipation support 41, and the heat dissipation inlet 431 is located on the bottom end of the heat dissipation base plate 43. The heat dissipation inlet 431 and the heat dissipation outlet 417 are respectively located at both ends of the heat dissipation support 41. In this embodiment, an air inlet nozzle 8 and a pneumatic silencer 9 are also included. The air inlet nozzle 8 has an L-shaped structure. One end of the air inlet nozzle 8 is connected to an external air source, and the other end of the air inlet nozzle 8 is connected to the heat dissipation inlet 431. The heat dissipation inlet 431 is connected to a heat dissipation air source. The pneumatic silencer 9 is installed on the heat dissipation outlet 417 and is used to reduce noise of the exhaust airflow.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
