Description

Technical Field

[0001] The utility model belongs to the technical field of lamp bodies, and particularly relates to a heat dissipation structure of a lamp body. Background Art

[0002] In the field of lamp body technology, it is necessary to use a heat dissipation structure to dissipate heat from the lamp body fixed in the lampshade. Specifically, the heat dissipation structure can dissipate heat from the lamp body by means of air intake and air outlet from the side of the lampshade (refer to Figure 1 In order to ensure the heat dissipation efficiency of the heat dissipation structure, the heat dissipation structure with air intake and air outlet from the side of the lampshade needs to use sufficiently thick heat exchange fins. Therefore, the related art has the problem that the heat dissipation structure is too thick and the production cost of the heat dissipation structure is high due to the need to use sufficiently thick heat exchange fins, which leads to a large lampshade and high production cost.

[0003] It should be noted that the above information disclosed in this section is only used to understand the background of the concept of the present invention, and therefore may contain information that does not constitute prior art. Utility Model Content

[0004] The purpose of the present application is to provide a heat dissipation structure of a lamp body, which can effectively solve the problem that the heat dissipation structure is too thick and the production cost of the heat dissipation structure is high due to the need to use sufficiently thick heat exchange fins.

[0005] The present application provides a heat dissipation structure of a lamp body, which is used to dissipate heat from a lamp body fixed in a lampshade. The heat dissipation structure of the lamp body includes:

[0006] Multiple heat exchange fins are arranged in sequence on the back of the lamp body;

[0007] The upper cover is fixed in the lampshade and is located on the side of the heat exchange fins away from the lamp body, and a plurality of cooling fans are installed on it;

[0008] The lampshade is provided with multiple air outlets on both sides of the length direction of the heat exchange fins, and the back of the lampshade is provided with multiple air inlet holes, and the cooling fan takes in air towards the back of the lamp body.

[0009] The heat dissipation structure of a lamp body provided in the present application is equivalent to using a heat dissipation structure in which air enters and exits from the side of the lampshade instead of a heat dissipation structure in which air enters and exits from the side of the lampshade. Compared with the heat dissipation structure in which air enters and exits from the side of the lampshade, the present application can effectively reduce the thickness of the heat exchange fins. Therefore, the present application can effectively solve the problem that the heat dissipation structure is too thick and the production cost of the heat dissipation structure is high due to the need to use sufficiently thick heat exchange fins. That is, the present application can effectively reduce the thickness of the heat dissipation structure and reduce the production cost of the heat dissipation structure, thereby effectively reducing the volume of the lampshade and reducing the production cost of the lampshade.

[0010] Furthermore, there are multiple cooling fans.

[0011] This technical solution has multiple cooling fans. Since multiple cooling fans can provide more sufficient airflow exchange for the heat exchange fins and multiple cooling fans can form a redundant design, this technical solution can effectively improve the cooling efficiency and reliability of the heat dissipation mechanism of the lamp body.

[0012] Furthermore, a plurality of cooling fans are sequentially arranged on the upper cover plate, and the arrangement direction of the cooling fans is parallel to the arrangement direction of the heat exchange fins.

[0013] Since the arrangement direction of the cooling fan of this technical solution is parallel to the arrangement direction of the heat exchange fins, this technical solution is equivalent to dissipating heat in different areas for multiple heat exchange fins, so that each heat exchange fin can be in contact with the gas that has not absorbed heat, thereby effectively improving the heat exchange efficiency between the heat exchange fins and the gas, and then effectively improving the heat dissipation efficiency of the heat dissipation structure of the lamp body.

[0014] Furthermore, the heat dissipation structure of the lamp body also includes a radiator base plate, the radiator base plate is fixedly connected to the lampshade, the lamp body is installed on the front side of the radiator base plate, and the heat exchange fins are installed on the back side of the radiator base plate.

[0015] Furthermore, a plurality of mounting blocks are fixed to the back of the radiator base plate, and the upper cover plate is fixedly connected to the mounting blocks.

[0016] Furthermore, a plurality of handles located outside the lampshade are provided on the radiator bottom plate.

[0017] Since a plurality of handles are provided on the radiator bottom plate of this technical solution, this technical solution can utilize the handles to move the lamp body and the heat dissipation structure of the lamp body, thereby effectively improving the convenience of moving the lamp body and the heat dissipation structure of the lamp body.

[0018] Furthermore, a plurality of fin mounting grooves are provided on the bottom surface of the radiator base plate, and a heat exchange fin group is installed in each fin mounting groove, and the heat exchange fin group includes a plurality of heat exchange fins.

[0019] Furthermore, the arrangement direction of the air inlet holes is parallel to the arrangement direction of the heat exchange fins.

[0020] Furthermore, the heat dissipation structure of the lamp body further includes a sealing component, which is arranged between the heat dissipation fan and the upper cover.

[0021] Furthermore, the lamp body includes a plurality of LED light panels.

[0022] From the above, it can be seen that the heat dissipation structure of the lamp body provided by the present invention is equivalent to using a heat dissipation structure in which air enters and exits from the side of the lampshade instead of a heat dissipation structure in which air enters and exits from the side of the lampshade. Compared with the heat dissipation structure in which air enters and exits from the side of the lampshade, the present application can effectively reduce the thickness of the heat exchange fins. Therefore, the present application can effectively solve the problem that the heat dissipation structure is too thick and the production cost of the heat dissipation structure is high due to the need to use sufficiently thick heat exchange fins. That is, the present application can effectively reduce the thickness of the heat dissipation structure and reduce the production cost of the heat dissipation structure, thereby effectively reducing the volume of the lampshade and reducing the production cost of the lampshade.

Of course, these are merely examples and are not intended to limit the present invention.

[0031] like Figure 2-Figure 5 As shown, the present application provides a heat dissipation structure of a lamp body, which is used to dissipate heat from a lamp body 2 fixed in a lampshade 1. The heat dissipation structure of the lamp body includes:

[0032] A plurality of heat exchange fins 5 are arranged in sequence on the back of the lamp body 2;

[0033] The upper cover 3 is fixed in the lampshade 1 and is located on the side of the heat exchange fins 5 away from the lamp body 2, and a plurality of cooling fans 4 are installed on it;

[0034] The lampshade 1 is provided with a plurality of air outlets 6 on both sides of the heat exchange fins 5 in the length direction, and a plurality of air inlet holes 7 are provided on the back of the lampshade 1 , and the cooling fan 4 takes in air towards the back of the lamp body 2 .

[0035] The heat exchange structure of the lamp body provided in this application is capable of dissipating heat from the lamp body 2 fixed within the lampshade 1. It should be understood that, since the lamp body 2 of this embodiment is fixed within the lampshade 1, and the heat dissipation structure of the lamp body of this embodiment is used to dissipate heat from the lamp body 2, the heat dissipation structure of the lamp body provided in this application is located within the lampshade 1. The heat exchange fins 5 of this embodiment can be existing heat exchange fins 5. This embodiment has a plurality of heat exchange fins 5, and the plurality of heat exchange fins 5 are sequentially arranged on the back surface of the lamp body 2 (the side of the lamp body 2 away from its light-emitting surface). The heat generated by the lamp body 2 during operation can be transferred to the heat exchange fins 5 by heat transfer. This embodiment can fix the upper cover plate 3 in the lampshade 1 and position the upper cover plate 3 on the side where the heat exchange fins 5 are away from the lamp body 2 by fixedly connecting the upper cover plate 3 to the inner wall of the lampshade 1 on the side where the heat exchange fins 5 are away from the lamp body 2. This embodiment can also fix the upper cover plate 3 in the lampshade 1 and position the upper cover plate 3 on the side where the heat exchange fins 5 are away from the lamp body 2 by fixedly connecting the upper cover plate 3 to the back side of the lamp body 2. Several cooling fans 4 are installed on the upper cover plate 3 of this embodiment. The cooling fans 4 can be existing cooling fans 4, that is, this embodiment is equivalent to arranging the heat exchange fins 5 between the lamp body 2 and the upper cover plate 3. The lampshade 1 of this embodiment is provided with a plurality of air outlet holes 6 on both sides of the length direction of the heat exchange fins 5, and the cooling fan 4 draws air toward the back of the lamp body 2 (that is, the air outlet of the cooling fan 4 is arranged toward the back of the lamp body 2). Preferably, the lampshade 1 of this embodiment can be divided into a front side (the side close to the light-emitting surface of the lamp body 2), a back side (the side away from the light-emitting surface of the lamp body 2) and four side surfaces (front side, rear side, left side and right side). The front side and rear side surfaces of the lampshade 1 are both provided with a plurality of air outlet holes 6, and the back surface of the lampshade 1 is provided with a plurality of air inlet holes 7. This embodiment is equivalent to air intake from the back of the lampshade 1 and air discharge from the sides of the lampshade 1, that is, the gas that has not absorbed heat enters the lampshade 1 from the back of the lampshade 1 and contacts the heat exchange fins 5 to absorb the heat of the heat exchange fins 5, and the gas that has absorbed heat flows out of the lampshade 1 from the sides of the lampshade 1.

[0036] The heat dissipation structure of the lamp body provided in the present application is equivalent to using a heat dissipation structure in which air enters from the back of the lampshade 1 and air exits from the side of the lampshade 1 instead of a heat dissipation structure in which air enters and exits from the side of the lampshade 1. Compared with the heat dissipation structure in which air enters and exits from the side of the lampshade 1, the present application can effectively reduce the thickness of the heat exchange fins 5. Therefore, the present application can effectively solve the problem that the heat dissipation structure is too thick and the production cost of the heat dissipation structure is high due to the need to use sufficiently thick heat exchange fins 5 for the heat dissipation structure. That is, the present application can effectively reduce the thickness of the heat dissipation structure and reduce the production cost of the heat dissipation structure, thereby effectively reducing the volume of the lampshade 1 and reducing the production cost of the lampshade 1.

[0037] In some embodiments, the ratio of the length of the heat exchange fin 5 to the height of the heat exchange fin 5 is 7:1-10:1. In this embodiment, the ratio of the length of the heat exchange fin 5 to the height of the heat exchange fin 5 is preferably 8.5:1.

[0038] In some embodiments, there are multiple cooling fans 4. In this embodiment, the number of cooling fans 4 is multiple. Since multiple cooling fans 4 can provide more sufficient airflow exchange for the heat exchange fins 5 and multiple cooling fans 4 can form a redundant design, this embodiment can effectively improve the heat dissipation efficiency and reliability of the heat dissipation mechanism of the lamp body.

[0039] In some embodiments, multiple cooling fans 4 are sequentially arranged on the upper cover 3, and the arrangement direction of the cooling fans 4 is parallel to the arrangement direction of the heat exchange fins 5. Since the arrangement direction of the cooling fans 4 in this embodiment is parallel to the arrangement direction of the heat exchange fins 5, this embodiment is equivalent to performing regional heat dissipation on the multiple heat exchange fins 5, so that each heat exchange fin 5 can come into contact with the gas that has not absorbed heat, thereby effectively improving the heat exchange efficiency between the heat exchange fins 5 and the gas, and further effectively improving the heat dissipation efficiency of the heat dissipation structure of the lamp body. The multiple cooling fans 4 in this embodiment are preferably sequentially arranged in the middle of the upper cover 3. Since the multiple cooling fans 4 in this embodiment are sequentially arranged in the middle of the upper cover 3, the distance from the air outlets 6 on both sides of the lampshade 1 to the same cooling fan 4 is the same, so that the heat is symmetrically dissipated on both sides of the lamp body 2.

[0040] In some embodiments, the heat dissipation structure of the lamp body further includes a radiator base plate 8, which is fixedly connected to the lampshade 1. The lamp body 2 is mounted on the front of the radiator base plate 8, and the heat exchange fins 5 are mounted on the back of the radiator base plate 8. In this embodiment, the side of the radiator base plate 8 close to the lamp body 2 is referred to as the front side of the radiator base plate 8, and the side of the radiator base plate 8 away from the lamp body 2 is referred to as the back side of the radiator base plate 8. The heat generated by the lamp body 2 during operation is transferred to the heat exchange fins 5 through the radiator base plate 8.

[0041] In some embodiments, a plurality of mounting blocks 9 are fixed to the back of the radiator base plate 8, and the upper cover plate 3 is fixedly connected to the mounting blocks 9. In this embodiment, the upper cover plate 3 is preferably fixedly connected to the mounting blocks 9 by screwing.

[0042] In some embodiments, the radiator base plate 8 is provided with a plurality of handles 10 located outside the lampshade 1. Since the radiator base plate 8 of this embodiment is provided with a plurality of handles 10, the lamp body 2 and the heat dissipation structure of the lamp body can be moved by using the handles 10, thereby effectively improving the convenience of moving the lamp body 2 and the heat dissipation structure of the lamp body.

[0043] In some embodiments, the bottom surface of the radiator base plate 8 is provided with multiple fin mounting slots 11, each of which is equipped with a heat exchange fin group comprising multiple heat exchange fins 5. Since the bottom surface of the radiator base plate 8 in this embodiment is provided with multiple fin mounting slots 11, and each of which is equipped with a heat exchange fin group comprising multiple heat exchange fins, this embodiment is equivalent to dissipating heat from the lamp body 2 in different regions, thereby achieving uniform temperature distribution of the lamp body 2.

[0044] In some embodiments, the arrangement direction of the air inlet holes 7 is parallel to the arrangement direction of the heat exchange fins 5 .

[0045] In some embodiments, the heat dissipation structure of the lamp body further includes a sealing assembly (not shown in the figures), which is disposed between the heat dissipation fan 4 and the upper cover plate 3. The sealing assembly in this embodiment can be a sealing ring or a sealing strip, etc., and by disposing the sealing assembly between the heat dissipation fan 4 and the upper cover plate 3, the gap between the heat dissipation fan 4 and the upper cover plate 3 is sealed, thereby effectively preventing the backflow of heat-absorbed gas through the gap between the heat dissipation fan 4 and the upper cover plate 3.

[0046] In some embodiments, the lamp body 2 includes a plurality of LED light boards. The LED light boards of this embodiment can be existing LED light boards. The lamp body 2 of this embodiment preferably includes four LED light boards.

[0047] From the above, it can be seen that the heat dissipation structure of the lamp body provided by the present invention is equivalent to using a heat dissipation structure in which air enters from the back of the lampshade 1 and air exits from the side of the lampshade 1 instead of a heat dissipation structure in which air enters and exits from the side of the lampshade 1. Compared with the heat dissipation structure in which air enters and exits from the side of the lampshade 1, the present application can effectively reduce the thickness of the heat exchange fins 5. Therefore, the present application can effectively solve the problem that the heat dissipation structure is too thick and the production cost of the heat dissipation structure is high due to the need to use sufficiently thick heat exchange fins 5 for the heat dissipation structure. That is, the present application can effectively reduce the thickness of the heat dissipation structure and reduce the production cost of the heat dissipation structure, thereby effectively reducing the volume of the lampshade 1 and reducing the production cost of the lampshade 1.
