[0021] A second heat dissipation channel is formed between the first gap, the first heat dissipation slot and the second gap.

[0022] Preferably, the heat dissipation structure further includes an anti-glare ring, which is disposed at the light-emitting end of the optical component, and a third gap is provided between the outer periphery of the anti-glare ring and the inner sidewall of the lamp body, the third gap connecting the outside of the lamp body and the first gap, and the second heat dissipation channel further includes the third gap.

[0023] Thirdly, this utility model also provides a lamp, including a light source assembly and the aforementioned heat dissipation lamp body or heat dissipation structure, wherein the light source assembly is mounted on the mounting surface.

[0024] In summary, this utility model has at least the following advantages:

[0025] 1. The heat dissipation lamp body provided by this utility model achieves a simplified structure and excellent heat dissipation effect through optimization of its internal structure. Specifically, the lamp body has an internal mounting platform, one side of which is used to mount the light source component. Heat sinks are provided between the outer periphery of the mounting platform and the inner wall of the lamp body. A first heat dissipation channel is formed between adjacent heat sinks, connecting the first cavity and the second cavity. The first heat dissipation channel promotes airflow inside the lamp body, effectively removing heat generated by the light source component from the outer periphery of the mounting platform, the surface of the heat sinks, and the surface of the lamp body. In addition, the mounting platform has a heat dissipation groove on the side near the second cavity, opposite to the light source component. The heat dissipation groove backs onto the light source component, allowing heat from the center of the light source component to be dissipated promptly. Furthermore, the heat dissipation groove cooperates with the outer heat sinks to solve the problem of uneven heat dissipation, thus achieving a small size and high heat dissipation efficiency.

[0026] 2. The heat dissipation structure provided by this utility model includes the aforementioned heat dissipation lamp body, and further optimizes the heat dissipation path of the heat dissipation lamp body to achieve better heat dissipation effect. Specifically, the heat dissipation structure has an end cap connected to one end near the second cavity.

[0049] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings and specific embodiments. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0050] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0051] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. 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. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0053] Example 1:

[0054] Please see Figures 1 to 3 This embodiment provides a heat dissipation lamp body 100, including a lamp body 10, a mounting platform 11, and heat sinks 12, which are disposed inside the lamp body 10. The lamp body 10 is a columnar structure extending through both ends. The mounting platform 11 is located at the center of the lamp body 10, and its outer side is connected to the inner wall of the lamp body 10 via the heat sinks 12. The interior of the lamp body 10 is divided by the mounting platform 11 to form a first cavity 13 and a second cavity 14. A first heat dissipation channel 15 connecting the first cavity 13 and the second cavity 14 is formed between adjacent heat sinks 12. By optimizing the structure of the lamp body 10, the mounting platform 11, and the heat sinks 12, the heat dissipation lamp body 100 creates a reasonable heat dissipation path inside the lamp body, achieving a simplified structure and high heat dissipation efficiency.

[0055] Furthermore, the mounting platform 11 has a mounting surface 111 for mounting the light source assembly on the side facing the first cavity 13. During the use of the light source assembly, the light source assembly generates heat, and airflow occurs inside the lamp body 10 due to the heat difference between different locations inside the lamp body 10. With the airflow, the area of ​​heat contact between the heat sink 12, the periphery of the mounting platform 11, and the inner wall of the lamp body 10 per unit time is increased, thereby enhancing the heat conduction effect of the heat sink 12 and improving the heat transfer efficiency between the heat sink 100 and the outside world.

[0056] In addition, the mounting platform 11 is also provided with a heat dissipation groove 112. The heat dissipation groove 112 is formed by the recess of the mounting platform 11 from the end near the second cavity 14 toward the end near the first cavity 13, and the position of the heat dissipation groove 112 is opposite to the position of the light source component fixed on the mounting surface 111. The setting of the heat dissipation groove 112 reduces the distance of heat transfer between the light source component and the mounting platform, which is conducive to the heat on the back of the light source component being transferred through the mounting platform 11 in a timely manner and entering the air at the heat dissipation groove 112.

[0057] The heat dissipation groove 112 facilitates heat dissipation from the middle part of the light source assembly, and the first heat dissipation channel 15 surrounds the mounting platform 11, promoting heat flow at the edges of the light source assembly. The heat dissipation groove 112 and the first heat dissipation channel 15 solve the problem of high local temperature in the middle of the light source assembly and low temperature at the edges, improving the overall heat dissipation effect and extending the life of the light source assembly.

[0058] Furthermore, the heat dissipation groove 112 includes a perimeter 115 surrounding its periphery, a slot 113 communicating with the second cavity 14, and a groove bottom 114 near the mounting surface 111. Specifically, the projection of the light source assembly onto the mounting surface 111 is covered by the projection of the groove bottom 114 onto the mounting surface 111, with the groove bottom 114 facing the light source assembly. That is, the area occupied by the groove bottom 114 at the bottom of the heat dissipation groove 112 is equal to or greater than the area occupied by the light source assembly, ensuring that the heat dissipation groove 112 can effectively conduct the heat generated by the light source assembly.

[0059] To further ensure uniform heat dissipation, heat sinks 12 are radially arranged around the periphery of the mounting platform 11 and connected to the inner wall of the lamp body 10. Each heat sink 12 includes a first end near the first cavity 13 and a second end near the second cavity 14. The first end of the heat sink 12 is flush with or protrudes from the surface of the mounting surface 111, and the second end is flush with or protrudes from the surface of the slot 113. This increases the vertical contact area between the heat sink 12 and the periphery of the mounting platform 11, as well as the length of the first heat dissipation slot 15, thereby improving heat dissipation.

[0060] It should be noted that the lamp body 10, mounting platform 11, and heat sink 12 are preferably formed by integral die casting technology to create the heat dissipation lamp body 100, giving it high structural strength and continuous thermal conductivity. Furthermore, integral die casting technology is not limited by shape. In this embodiment, the heat dissipation lamp body 100 has a first opening 131 connected to the first cavity 13 and a first opening 141 connected to the second cavity 14 at both ends, wherein the first opening 131 is larger than the first opening 141, and the heat dissipation lamp body 100 is approximately frustum-shaped.

[0061] Example 2:

[0062] This embodiment provides a heat dissipation structure 200 based on Embodiment 1. The heat dissipation structure 200 includes a heat dissipation lamp body 100 and an end cap 20. The heat dissipation structure 200 optimizes the heat dissipation path between the heat dissipation lamp body 100 and the end cap 20 to achieve better heat dissipation. For the similarities of the heat dissipation lamp body 100, please refer to Embodiment 1. The heat dissipation structure 200 will be described in detail below.

[0063] Please refer to Figures 2 to 8 An end cap 20 is installed at one end of the heat dissipation lamp body 100 near the second cavity 14, and the end cap 20 is connected to the second cavity 14. The end cap 20 has a second heat dissipation channel 21 connecting the second cavity 14 and the outside. A first heat dissipation channel (not shown in the figure) is formed between the first heat dissipation channel 15 and the second heat dissipation channel 21. The first heat dissipation channel provides a passage for air circulation inside and outside the heat dissipation structure 200, thereby facilitating the dissipation of heat inside the heat dissipation lamp body 100.

[0064] The opening position of the second heat dissipation channel 21 on the end cover 20 corresponds to the opening position of the first heat dissipation channel 15, promoting smooth air circulation. In some embodiments, the second heat dissipation channel 21 is opened along the outer periphery of the end cover 20, and the opening shape and opening size of the second heat dissipation channel 21 are the same as the opening shape and opening size of the first heat dissipation channel 15, and they correspond one-to-one; the projections of the second heat dissipation channel 21 and the first heat dissipation channel 15 on the end cover 20 coincide with each other.

[0065] Furthermore, the heat dissipation structure 200 also includes an optical component 30, which is located within the first cavity 13. A first gap 31 is formed between the periphery of the optical component 30 and the inner wall of the lamp body 10, connecting the interior of the lamp body 10 and the first cavity 13, allowing air outside the heat dissipation lamp body 100 to circulate with air inside the lamp body 100. Similarly, a second gap 22 is formed between the periphery of the end cap 20 and the inner wall of the lamp body 10, connecting the heat dissipation lamp body 100 and the second cavity 14, allowing air outside the heat dissipation lamp body 100 to circulate with air inside the lamp body 100. A second heat dissipation channel 50 is formed between the first gap 31, the first heat dissipation groove 15, and the second gap 22.

[0066] The second heat dissipation channel 50 makes the heat dissipation structure 200 a hollow structure with good air circulation. The cooperation between the first and second heat dissipation channels 50 facilitates the formation of a circulating airflow inside the heat dissipation structure 200, thereby transferring heat from the inside of the heat dissipation lamp body 100 to the outside. The mounting platform 11 transfers heat to the lamp body 10 through the heat sink 12, enabling heat exchange between the lamp body 10 and the outside air, and also promoting heat dissipation from the second heat dissipation slot 21 of the end cover 20.

[0067] In some embodiments, the heat dissipation structure 200 further includes an anti-glare ring 40 disposed at the light-emitting end of the optical component 30, and a third gap 41 is formed between the outer periphery of the anti-glare ring 40 and the inner sidewall of the lamp body 10. The third gap 41 connects the outside of the lamp body 10 and the first gap 31, thereby forming the second heat dissipation channel 50 by sequentially connecting the third gap 41, the first gap 31, the first heat dissipation channel 15 and the second gap 22, ensuring the integrity of the air circulation of the heat dissipation structure 200 and guaranteeing the heat dissipation effect.

[0068] In this embodiment, the second gap 22 is preferably an annular gap formed around the periphery of the second heat dissipation channel 21. It is understood that in some embodiments, the first gap 31, the second gap 22, and the third gap 41 may contain obstructions, i.e., gap structures that are not completely closed.

[0069] Example 3:

[0070] This embodiment provides a lamp 300 based on the above embodiments. The lamp 300 includes a light source assembly 60 and a heat dissipation structure 200, or a light source assembly 60 and a heat dissipation lamp body 100. In this embodiment, the lamp 300 including the light source assembly 60 and the heat dissipation structure 200 provided in Embodiment 2 is described as an example. For similarities, please refer to Embodiments 1 and 2.

[0071] like Figures 9 to 11As shown, the light source assembly 60 is mounted on the mounting surface 111 of the mounting platform 11, and the light-emitting side of the light source assembly 60 faces the first opening 131 corresponding to the first cavity 13. Further, an optical assembly 30 is mounted on the light-emitting side of the light source assembly 60, and the optical assembly 30 includes a reflector, a lens, and a fixing member. The fixing member is connected to the anti-glare ring 40 on the light-emitting side.

[0072] At the other end of the heat dissipation structure 200, a power supply assembly 70 is mounted on the side of the end cover 20 near the second cavity 14. The power supply assembly 70 is fixed to the inside of the end cover 20 by potting thermally conductive adhesive, so as to further improve the heat dissipation efficiency by utilizing the thermal conductivity of the thermally conductive adhesive, and at the same time, the thermally conductive adhesive protects the electronic components inside the power supply assembly 70.

[0073] It should be noted that the end cover 20 is provided with a mounting part for the power supply component 70. The first heat dissipation channel 15 is preferably formed on the periphery of the mounting part, and the projection of the power supply component 70 on the end cover 20 should also avoid the first heat dissipation channel 15 to ensure the heat dissipation effect of the first heat dissipation channel 15 is guaranteed.

[0074] Furthermore, a mounting component 80 is also connected to the end cover 20. The mounting component 80 can be a ceiling-mounted component, a rail-mounted structure, or any other structure. The lamp 300 provided in this embodiment is a rail lamp, and a rail-mounted component is rotatably connected to the end cover 20.

[0075] Figure 11 A schematic diagram illustrating the heat dissipation effect of the heat dissipation structure 200 provided in this embodiment is given. During operation, the maximum temperature of the lamp 300 occurs near the power supply component 70 and the light source component 60. The heat dissipation structure 200 facilitates airflow between the inside and outside of the lamp body 10, accelerating heat dissipation within the lamp 300. Specifically, the heat dissipation groove 112 facilitates heat dissipation from the back of the light source component 60, and the cooperation of the first and second heat dissipation channels 50 helps dissipate heat from the periphery of the light source component 60. Figure 11 It can be seen that the temperature difference between the high temperature near the light source component 60 and other parts inside the lamp body is at least 22℃, which shows that the heat dissipation structure 200 has a good heat dissipation effect.

[0076] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
