Description

Technical Field

[0001] This utility model relates to the field of LED lamp heat dissipation technology, specifically to an LED lamp with high-efficiency heat dissipation. Background Technology

[0002] As we all know, LED lights are lighting devices that use semiconductor light-emitting diodes as light sources. They are characterized by high efficiency, energy saving, long lifespan, and environmental friendliness, and are widely used in indoor lighting, outdoor lighting, automotive lighting, and other fields. By injecting current into semiconductor materials, charge carriers recombine to generate a photoelectric effect, thereby achieving light emission. They have advantages such as high efficiency, energy saving, long lifespan, safety, and environmental protection, and are the future development direction of the lighting industry.

[0003] However, traditional LED lights generate a certain amount of heat when working, especially in hot weather, where the heat accumulation is severe. At the same time, with the continuous development of LED lighting technology, there are more and more large LED lights. However, due to insufficient heat dissipation design, the heat usually cannot be dissipated quickly. Conventional heat dissipation methods cannot meet the heat dissipation requirements of large LED lights, resulting in heat accumulation inside the lamp body, reducing brightness and lifespan.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an LED light with high heat dissipation efficiency, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide an LED lamp with high-efficiency heat dissipation to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A high-efficiency heat dissipation LED lamp includes a housing, a heat dissipation mechanism, a lamp body, and a fan. A mounting bracket is fixedly connected to one side of the housing. A heat dissipation cavity is formed on the side of the housing away from the mounting bracket. A placement cavity is formed on the side of the housing located in the heat dissipation cavity. The heat dissipation mechanism includes a cooling pipe, a heat sink, a water tank, a chiller, and a heat-conducting plate. The cooling pipe is located in the heat dissipation cavity, with its ends on the same side and penetrating into the placement cavity and communicating with each other. The portion of the cooling pipe located in the placement cavity is connected to the water tank and the chiller. The heat sink is vertically fixed to the inner wall of the heat dissipation cavity near the mounting bracket. The heat-conducting plate is fixed to the side of the heat sink away from the mounting bracket. The heat sink and the heat-conducting plate are perpendicular to each other. The lamp body is located on the side of the heat-conducting plate away from the heat sink, and the outer diameter of the lamp body is clearance-fitted with the inner diameter of the heat dissipation cavity.

[0008] Furthermore, both the cooling pipe and the water tank are filled with cooling water, and the portion of the cooling pipe located in the heat dissipation cavity extends through the heat dissipation fins in a continuous U-shape.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the continuous U-shaped cooling pipe penetrating the heat sink can increase the contact area between the cooling pipe and the heat sink, and when the cold water pipe passes through the heat sink, it can effectively conduct heat and cool the heat sink.

[0010] Furthermore, the lamp body is fixed inside the heat dissipation cavity by bolts, and the inner side of the lamp body is in close contact with the heat-conducting plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the lamp body is fixed by bolts, which makes it easy to disassemble, and the heat-conducting plate is closely attached to the inside of the lamp body, which can quickly transfer the heat generated by the lamp body after being powered on to the heat-conducting plate.

[0012] Furthermore, a fan is provided at the bottom of the heat dissipation cavity.

[0013] The beneficial effect of adopting the above-described further solution is that by using a fan to dissipate heat from the heat dissipation cavity, the heat dissipation efficiency can be further improved. Furthermore, a dust filter is provided on the top of the heat dissipation cavity.

[0014] The advantage of adopting the above-mentioned further solution is that it avoids dust accumulation in the vents, which would impede airflow in the heat dissipation cavity and affect heat dissipation.

[0015] Furthermore, a control panel is provided on one side of the housing, and the control panel is communicatively connected to the refrigeration unit and the fan.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the refrigerator and fan switch can be controlled by setting a predetermined program through the control panel. Furthermore, the placement cavity is equipped with a digital thermometer, the temperature measuring end of which extends into the heat dissipation cavity and is close to the lamp body.

[0017] Furthermore, the control panel is communicatively connected to the digital thermometer.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the temperature of the lamp body can be detected in real time by a digital thermometer, and the temperature data can be transmitted to the control panel. The cooling unit and the fan switch can be controlled by setting a predetermined program through the control panel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a heat dissipation mechanism, a heat-conducting plate on one side of the lamp body will transfer heat to the heat sink on the side of the heat-conducting plate. The continuous U-shaped cooling pipe passing through the heat sink can increase the contact area between the cooling pipe and the heat sink. When the cooling water in the cooling pipe heats up, the cooling water in the closed loop will flow naturally. When the cooling pipe passes through water, it can effectively conduct heat and cool the heat sink. By providing a digital thermometer to detect the lamp body temperature in real time, the temperature data is transmitted to the control panel. The switch of the chiller and fan can be controlled by setting a predetermined program on the control panel. When the lamp body temperature is too high, the chiller and fan start. The chiller cools the cooling water in the cooling pipe, and the fan further dissipates heat from the heat dissipation cavity, which greatly improves the heat dissipation efficiency of the lamp body and can effectively protect the lamp body.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 6 This utility model provides a technical solution including a housing 100, a heat dissipation mechanism 200, a lamp body 300, and a fan 400. A mounting bracket 1001 is fixedly connected to one side of the housing 100, and the housing 100 is fixed to a wall or ground via the mounting bracket 1001. A heat dissipation cavity 1002 is formed on the side of the housing 100 away from the mounting bracket 1001, and a placement cavity 1003 is formed on the side of the housing 100 located in the heat dissipation cavity 1002. The heat dissipation mechanism 200 includes a cooling pipe 200. 1. A heat sink 2002, a water tank 2003, a chiller 2004, a heat-conducting plate 2005, and a cooling pipe 2001 are disposed in the heat dissipation cavity 1002. The beginning and end of the cooling pipe 2001 are located on the same side and pass through the placement cavity 1003 and are interconnected. The cooling pipe 2001 located in the placement cavity 1003 is connected to the water tank 2003 and the chiller 2004. The heat sink 2002 is vertically fixed to the inner wall of the heat dissipation cavity 1002 near the mounting bracket 1001. A heat-conducting plate 2005 is fixed on the side away from the mounting bracket 1001. The heat sink 2002 is perpendicular to the heat-conducting plate 2005. A lamp body 300 is located on the side of the heat-conducting plate 2005 away from the heat sink 2002. The outer diameter of the lamp body 300 is clearance-fitted with the inner diameter of the heat dissipation cavity 1002. Both the cooling pipe 2001 and the water tank 2003 are filled with cooling water. The portion of the cooling pipe 2001 located in the heat dissipation cavity 1002 is a continuous U-shape that passes through the heat sink 2002. The lamp body 300 is secured by bolts. Fixed inside the heat dissipation cavity 1002, the inner side of the lamp body 300 is closely attached to the heat conduction plate 2005. The continuous U-shaped cooling pipe 2001 passes through the heat sink 2002, which can increase the contact area between the cooling pipe 2001 and the heat sink 2002. When the cooling water in the cooling pipe 2001 heats up, the cooling water in the closed loop will flow naturally. When the cooling pipe 2001 is filled with water, it can effectively conduct heat and cool down the heat sink 2002, thereby achieving the effect of heat dissipation and cooling of the lamp body 300.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 - Figure 6 The present invention provides a technical solution: a fan 400 is provided at the bottom of the heat dissipation cavity 1002 and a dust filter 1004 is provided at the top of the heat dissipation cavity 1002. The heat dissipation cavity 1002 is cooled by the fan 400, which can further improve the heat dissipation efficiency. The dust filter 1004 can prevent dust from accumulating in the vents, thereby preventing poor air circulation in the heat dissipation cavity 1002 and affecting heat dissipation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a control panel 600 is provided on one side of the housing 100. The control panel 600 is communicatively connected to the refrigerator 2004 and the fan 400. A digital thermometer 500 is provided in the placement cavity 1003. The temperature measuring end of the digital thermometer 500 extends into the heat dissipation cavity 1002 and is close to the lamp body 300. The control panel 600 is communicatively connected to the digital thermometer 500. The temperature of the lamp body 300 is detected in real time by the digital thermometer 500. After the temperature data is transmitted to the control panel 600, the refrigerator 2004 and the fan 400 can be controlled by setting a predetermined program through the control panel 600.

[0033] Specifically, the working principle and usage of this high-efficiency heat dissipation LED lamp are as follows: Before use, check that all components are intact. Then, select the heat dissipation temperature according to the actual situation and input the heat dissipation temperature into the control panel 600. When the lamp body 300 is in use, the temperature inside the lamp body 300 gradually rises, and heat begins to accumulate. At this time, the heat dissipation mechanism 200 starts to work. The heat-conducting plate 2005 on one side of the lamp body 300 will transfer heat to the heat sink 2002 on one side of the heat-conducting plate 2005. The continuous U-shaped cooling pipe 2001 passes through the heat sink 2002, which can increase the contact area between the cooling pipe 2001 and the heat sink 2002. When the cooling water in the cooling pipe 2001 heats up, the cooling water in the closed loop will flow naturally. When water flows through the cooling pipe 2001, it can effectively dissipate heat. The heat sink 2002 is cooled by heat conduction. A digital thermometer 500 monitors the temperature of the lamp body 300 in real time and transmits the temperature data to the control panel 600. The chiller 2004 and fan 400 are normally off to save power. When the temperature reaches the predetermined heat dissipation temperature, the control panel 600 starts the chiller 2004 and fan 400. The chiller 2004 cools the cooling water in the cooling pipe 2001, and the fan 400 further dissipates heat from the heat dissipation cavity 1002, which greatly improves the heat dissipation efficiency of the lamp body 300. This achieves multiple heat dissipation for the lamp body 300, effectively protecting the lamp body 300 and extending its lifespan while ensuring its continued use. This practical structure is simple, easy to operate, and has high practical value.
