A UFO lamp with high heat dissipation efficiency

Abstract

This utility model discloses a UFO light with high heat dissipation efficiency, comprising a drive assembly, a heat sink, and a light source assembly assembled from top to bottom. A first air vent is located at the bottom of the heat sink, and a second air vent is located at its top, with the first and second air vents communicating to form a heat dissipation airflow channel. During operation, the air within the heat dissipation airflow channel is gradually heated by the light source assembly, causing the air density to gradually decrease. The hot air is then naturally discharged from the second air vent at the top. To fill the discharged air, cooler, denser air from outside the UFO light is drawn in through the first air vent at the bottom, thus forming a self-driven, continuous cooling airflow—the "chimney effect." This design increases the effective heat dissipation area, enhances airflow, and directly targets the heat source for heat dissipation, significantly improving the heat dissipation efficiency of the UFO light, thereby ensuring the lifespan of the lamp and improving the stability and reliability of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of UFO light technology, and in particular to a UFO light with high heat dissipation efficiency. Background Technology

[0002] UFO lights, named for their disc-shaped appearance resembling a UFO, are primarily composed of a driver assembly, heat sink, and light source assembly assembled from top to bottom. They are high-efficiency LED lighting devices designed for large spaces with ceiling heights of 6-20 meters, such as factory workshops, logistics warehouses, stadiums, and shopping malls. Existing UFO lights have heat dissipation fins on the top surface of the heat sink. The heat generated by the light source assembly during operation is dissipated by the heat sink through thermal radiation and natural convection between the fin surface and the surrounding air, ensuring stable operation. However, existing UFO light heat sinks suffer from low heat dissipation efficiency—in high-temperature environments such as summer or high-temperature production workshops, heat cannot be dissipated in time. This not only accelerates light decay (the light dims over time) and shortens the lifespan of the light fixture, but can also lead to overheating and damage, affecting the normal operation of the lighting system. Utility Model Content

[0003] The main purpose of this invention is to propose a UFO light with high heat dissipation efficiency, aiming to solve the technical problem that existing UFO lights only dissipate heat outward through air convection via heat dissipation fins, resulting in low heat dissipation efficiency.

[0004] To achieve the above objectives, the present invention proposes a UFO lamp with high heat dissipation efficiency, comprising a driving component, a heat sink, and a lamp source component assembled from top to bottom; the bottom of the heat sink is provided with a first air hole, and the top of the heat sink is provided with a second air hole, the first air hole and the second air hole are connected to form a heat dissipation airflow channel.

[0005] Optionally, the heat dissipation airflow channel is provided with internal heat dissipation fins.

[0006] Optionally, the cooling airflow channel is provided with external cooling fins.

[0007] Optionally, the bottom of the radiator is provided with a lower connecting boss, the lamp source assembly is provided with a mounting hole, the lower connecting boss extends into the mounting hole, and the first vent is provided at the lower connecting boss.

[0008] Optionally, there are multiple first air holes, which are evenly distributed along the outer periphery of the lower connecting boss.

[0009] Optionally, the top of the heat sink is provided with an upper connecting boss, the bottom of the drive assembly is connected to the upper connecting boss, and the second air hole is disposed between the upper connecting boss and the drive assembly.

[0010] Optionally, there are multiple second air holes, which are evenly distributed along the outer periphery of the upper connecting boss.

[0011] Optionally, the bottom surface of the drive assembly is located within a heat dissipation airflow channel.

[0012] Optionally, a ventilation fan is provided inside the heat dissipation airflow channel.

[0013] Optionally, the lamp source assembly, heat sink, and drive assembly are all provided with wire tubes, and the wire tubes of the lamp source assembly, heat sink, and drive assembly can be nested to form a continuous wire channel.

[0014] The technical solution of this utility model has the following beneficial effects: During the operation of the UFO light, the air inside the cooling airflow channel is gradually heated by the light source component, causing the air density to gradually decrease. The hot air is then naturally discharged from the second vent at the top. To fill the discharged air, cooler, denser air from outside the UFO light is drawn in from the first vent at the bottom, thus forming a self-driven, continuous cooling airflow—the "chimney effect." Compared to the heat radiation and natural convection between the heat sink fins and the surrounding air in existing UFO lights, the cooling airflow channel increases the effective heat dissipation area, making the internal channel walls through which the airflow passes a heat dissipation surface; it also enhances airflow—the directional airflow formed by the "chimney effect" is much faster than the natural convection outside the UFO light; and it directly targets the heat source—the lower connecting boss extends into the middle of the light source component, where the heat is most concentrated, and the first vent here allows for precise source cooling. In summary, the heat dissipation airflow channel can significantly improve the heat dissipation efficiency of UFO lights. Even in special scenarios such as high-temperature environments in summer or high-temperature production workshops, it can dissipate heat in a timely manner, thereby ensuring the service life of the lights and improving the stability and reliability of the equipment.

[0022] This invention proposes a UFO lamp with high heat dissipation efficiency.

[0023] like Figures 1 to 5As shown in Embodiment 1 of this utility model, the high-heat-dissipation-efficiency UFO lamp includes a driving assembly 3, a heat sink 2, and a lamp source assembly 1 assembled sequentially from top to bottom. Specifically, the driving assembly 3 includes a lifting ring 31, a driving housing 32, a combined circuit board 33, and a sealing plate 34. The lifting ring 31 is disposed on the top of the driving housing 32, the combined circuit board 33 is installed inside the driving housing 32, and the sealing plate 34 is disposed on the bottom of the driving housing 32 to seal the driving housing 32. Further, the body of the heat sink 2 is a hollow, partially spherical shape. A lower connecting boss is provided inside the hollow interior (bottom) of the heat sink 2, and multiple first screw holes 25 are provided on the outer ring of the lower connecting boss. The first bolt 4 passes through the lamp source assembly 2 and connects with the first screw holes 25, thereby installing the lamp source assembly inside the hollow interior of the heat sink 2, and the lower connecting boss extends into the mounting hole 14 in the middle of the lamp source assembly 1. A top connecting boss is provided on the top of the radiator 2. The top connecting boss is ring-shaped. The drive housing 32 and the sealing plate 34 are connected to the top connecting boss by the second bolt 5.

[0024] Furthermore, the light source assembly 1 includes a lamp mounting plate 11, a mounting housing 12, and LED beads 13. The mounting housing 12 has multiple annular lamp covers 121 to accommodate the LED beads 13, and a bolt cover 6 to shield and protect the first bolt 4. The lamp mounting plate 11 has multiple lamp mounting through holes 111 for the first bolt 4 to pass through. Several LED beads 13 are evenly arranged between the lamp mounting plate 11 and the annular lamp covers 121. The first bolt 4 passes sequentially through the mounting housing 12 and the lamp mounting plate 11 and connects to the first screw hole 25, thereby completing the assembly of the mounting housing 12, the lamp mounting plate 11, and the heat sink 2, and fixing the LED beads 13.

[0025] In this embodiment, a first vent 23 is provided at the bottom of the radiator 2, and a second vent 24 is provided at the top of the radiator 2. The first vent 23 and the second vent 24 are connected to form a heat dissipation airflow channel. This heat dissipation airflow channel runs through the middle of the radiator 2. Air can enter from the first vent 23 at the bottom of the radiator 2, and after flowing through the heat dissipation airflow channel in the middle of the radiator 2, it flows out from the second vent 24 at the top (air can also enter from the second vent 24 and flow out from the first vent 23), thereby carrying away some of the heat generated by the lamp source assembly 1 and the drive assembly 3.

[0026] During the operation of the UFO light, the air in the cooling airflow channel is gradually heated by the light source component 1, causing the air density to gradually decrease. Then, the hot air is naturally discharged from the second vent 24 at the top. To fill the discharged air, cold air with a lower temperature and higher density from outside the UFO light is drawn in from the first vent 23 at the bottom, thus forming a self-driven, continuous cooling airflow—the "chimney effect." Compared to the heat radiation and natural convection between the surface of the heat sink fins and the surrounding air in existing UFO lights, the cooling airflow channel increases the effective heat dissipation area, making the internal channel wall through which the airflow passes a heat dissipation surface; it also enhances airflow—the directional airflow formed by the "chimney effect" has a much higher speed than the natural convection outside the UFO light; and it directly dissipates heat from the heat source—the lower connecting boss extends into the middle of the light source component 1, which is the area with the most concentrated heat. The first vent 23 is located here, which allows for precise source cooling. In summary, the heat dissipation airflow channel can significantly improve the heat dissipation efficiency of UFO lights. Even in special scenarios such as high-temperature environments in summer or high-temperature production workshops, it can dissipate heat in a timely manner, thereby ensuring the service life of the lights and improving the stability and reliability of the equipment.

[0027] It is worth noting that the aforementioned second vent 24 is located between the upper connecting boss and the drive assembly 3, and the bottom surface of the sealing plate 34 is located within the heat dissipation airflow channel. This design helps to remove the heat generated by the drive assembly 3 through the heat dissipation airflow channel, thereby further ensuring the service life of the drive assembly 3 and improving its stability and reliability in use.

[0028] like Figure 2 , 3 As shown in Figure 4, both the frustum-shaped lower connecting boss and the annular upper connecting boss are hollow inside and interconnected to form a heat dissipation airflow channel. Furthermore, the upper connecting boss is located in the center of the top surface of the radiator 2, with approximately half of the inner ring area of ​​the top surface of the radiator 2 located within the inner ring of the upper connecting boss, and the other half of the outer ring area located within the outer ring of the upper connecting boss. Inner heat dissipation fins 22 are provided within the inner ring of the upper connecting boss, i.e., within the heat dissipation airflow channel, to further increase the heat dissipation area within the airflow channel, thereby further improving the heat dissipation efficiency of the airflow channel. Outer heat dissipation fins 21 are provided outside the outer ring of the upper connecting boss, i.e., outside the heat dissipation airflow channel. This design allows the outer heat dissipation fins 21 to be combined with the heat dissipation airflow channel to further expand and improve the heat dissipation effect of the "chimney effect," and also facilitates the full utilization of the external air in the heat dissipation airflow channel for heat radiation heat dissipation, thereby further improving the heat dissipation efficiency.

[0029] Preferably, there are multiple first air holes 23, which are evenly distributed along the outer periphery of the lower connecting boss. This design facilitates the first air holes 23 to draw in more air evenly over a larger area, thereby dissipating heat from a larger area of ​​the lamp source assembly 1. It also helps the air entering from the first air holes 23 to come close to the inner heat dissipation fins 22 to carry away heat.

[0030] Preferably, there are multiple second air holes 24, which are evenly distributed along the outer periphery of the upper connecting boss. This design facilitates the uniform flow of air through the heat dissipation air channel and then evenly exits from each of the second air holes 24, thereby maximizing the heat dissipation performance of the heat dissipation air channel and the inner heat dissipation fins 22, and also allows the air to fully contact the bottom surface of the sealing plate 34, thereby carrying away the heat generated by the drive component 3.

[0031] Preferably, a ventilation fan (not shown in the figure) is provided inside the hollow lower connecting boss, at the connection between the top and bottom surfaces of the heat sink 2, or inside the hollow upper connecting boss. The ventilation fan can be powered by the drive component 3, or it can be set independently and rotated solely by air convection. Providing a ventilation fan can further increase the air convection rate within the heat dissipation airflow channel, thereby further improving heat dissipation efficiency. If the drive component 3 powers the ventilation fan, it can also actively accelerate air convection when air convection is weak, improving the heat dissipation efficiency of the UFO light under conditions of weak air convection.

[0032] Preferably, the lamp source assembly 1, heat sink 2, and drive assembly 3 are all equipped with wire tubes (not shown in the figure). During the assembly process, the wire tubes of the three components can be nested to form a continuous wire channel, through which wires are threaded to electrically connect the drive assembly 3 and the lamp source assembly 1 (and the ventilation fan powered by the drive assembly 3). With the drive assembly 3 and the lamp source assembly 1 each achieving a certain degree of sealing through their respective structures, the wire tubes and wire channels not only connect the drive assembly 3 and the lamp source assembly 1 (and the ventilation fan), but also prevent dust and moisture from entering the drive assembly 3 and the lamp source assembly 1 along the wires, thereby ensuring the service life and operational stability and reliability of the drive assembly 3 and the lamp source assembly 1.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
