Description

Technical Field

[0001] This application relates to the field of lighting technology, and more particularly to a luminaire. Background Technology

[0002] Lighting fixtures are commonly used devices in the field of lighting technology. Lighting fixtures are equipped with heat sinks to dissipate the heat generated during lighting to the outside of the fixture in a timely manner, so as to prevent the fixture temperature from becoming too high and affecting the normal lighting.

[0003] In existing technologies, the heat sink is integrally molded onto the lamp. Due to the complex structure of the lamp itself, integral molding presents significant manufacturing challenges. Furthermore, when a component of the lamp, such as the heat sink fins on the outer wall, is damaged, the entire lamp needs to be disassembled for maintenance or replaced, increasing the operating cost of the lamp. Utility Model Content

[0012] In one of the alternative technical solutions, the mounting ring has a top wall, the main body fin is mounted on the top wall, and the top wall also has a through hole.

[0013] In one of the alternative technical solutions, the first step surface of the first limiting step is a plane, and the second step surface of the second limiting step is a plane or an inclined plane; when the second step surface is an inclined plane, the second step surface is inclined outward along the radial direction of the heat dissipation body in a direction away from the first step surface.

[0039] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0040] It is readily understood that, based on the technical solution of this utility model, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0041] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0042] like Figures 1 to 6 As shown, this utility model provides a lamp, including: a heat dissipation shell 1 and a heat dissipation body 2, which are separately arranged.

[0043] The heat dissipation shell 1 has a first limiting step 10 inside, and shell fins 11 are provided on the heat dissipation shell 1. The shell fins 11 are provided with a first limiting structure 110, such as... Figure 5 and Figure 8As shown. The heat dissipation body 2 includes a mounting ring 20 and main body fins 21 located on the mounting ring 20. The mounting ring 20 has a second limiting step 200 inside, and the main body fins 21 have a second limiting structure 210, as shown. Figures 9 to 10 As shown.

[0044] Both the heat sink 1 and the heat sink body 2 can be made of metal materials to increase the heat dissipation effect of the lamp.

[0045] During assembly, the heat sink 1 is fitted onto the outside of the heat sink body 2. The first limiting structure 110 and the second limiting structure 210 are engaged to limit the heat sink 1 in the circumferential direction, preventing the heat sink 1 from rotating relative to the heat sink body 2. The first limiting step 10 and the second limiting step 200 are engaged to limit the heat sink in the vertical direction, thereby making the heat sink 1 stably set on the heat sink body 2.

[0046] Therefore, the lamp provided by this utility model has a separate heat sink 1 and a heat sink body 2. A first limiting step 10 is provided inside the heat sink 1, and a first limiting structure 110 is provided on the shell fins 11. A second limiting step 200 is provided inside the heat sink body 2, and a second limiting structure 210 is provided on the main body fins 21 of the heat sink body 2. The heat sink 1 is stably installed on the heat sink body 2 by the first limiting step 10 and the second limiting step 200 being connected and the first limiting structure 110 and the second limiting structure 210 being engaged. When either the heat sink 1 or the heat sink body 2 is damaged, the damaged part can be disassembled, repaired, or replaced separately. Compared with repairing or replacing the entire lamp, this significantly reduces the operating cost of the lamp.

[0047] In an optional embodiment where the first limiting structure 110 and the second limiting structure 210 engage, the first limiting structure 110 includes a strip-shaped groove, and the second limiting structure 210 includes a engaging portion extending radially outward from the mounting ring 20, the engaging portion engaging with the groove. Figure 7 As shown, the slot of the first limiting structure 110 is a groove extending vertically along the shell fin 11; as Figures 9 to 10 As shown, the snap-fit ​​part is a convex strip extending vertically along the main body fin 21. After the snap-fit ​​part snaps into the slot, it provides stable and reliable positioning of the heat sink 1 in the circumferential direction.

[0048] In another optional embodiment where the first limiting structure 110 and the second limiting structure 210 engage, the first limiting structure 110 includes a protrusion protruding from the inner wall of the housing fin 11, and the second limiting structure 210 includes a groove recessed within the main body fin 21, with the protrusion engaging with the groove. In this embodiment, the protrusion protrudes from the inner wall of the housing fin 11 and extends vertically, while the groove is recessed within the main body fin 21 and extends vertically. After the protrusion engages with the groove, it also provides a stable and reliable circumferential limiting effect on the heat sink 1.

[0049] In an optional embodiment, there are at least two main body fins 21, which are arranged circumferentially along the mounting ring 20, and at least one main body fin 21 is provided with a first limiting structure 110; there are at least two shell fins 11, which are arranged circumferentially along the heat dissipation shell 1 and correspond one-to-one with the at least two main body fins 21, and at least one shell fin 11 is provided with a second limiting structure 210; at least one first limiting structure 110 and at least one second limiting structure 210 are engaged one-to-one. Figures 7 to 10 In the optional embodiment shown, there are twelve main body fins 21 and twelve shell fins 11, and they correspond one to one. The first limiting structure 110 and the second limiting structure 210 are both one and compatible.

[0050] In addition, the number of main body fins 21 and shell fins 11 can be adjusted adaptively according to the heat dissipation requirements of the lamp.

[0051] In an optional embodiment, the mounting ring 20 has a top wall 201, the main body fins 21 are mounted on the top wall 201, and the top wall 201 also has a through hole 202. Figure 1 , Figure 3 and Figure 10 As shown, the through holes 202 located on the main body fins 21 can serve as a passage for wires, such as power cables, which can extend out of the heat dissipation body 2 through the through holes 202. At the same time, the through holes 202 can increase the heat dissipation effect to a certain extent.

[0052] Furthermore, the through hole 202 is formed between the main body fins 21 to avoid positional interference between the through hole 202 and the main body fins 21.

[0053] In an optional embodiment, the first step surface 100 of the first limiting step 10 is a plane, and the second step surface 203 of the second limiting step 200 is a plane or an inclined plane, such as... Figure 5As shown, when the second step surface 203 is an inclined plane, it slopes outwards along the radial direction of the heat dissipation body 2 in a direction away from the first step surface 100. When the second step surface 203 is set as a plane, the mutually planar second step surface 203 and the first step surface 100 fit together, which helps to increase the tightness of the assembly; when the second step surface 203 is set as an inclined plane, the inner sides of the first step surface 100 and the second step surface 203 still abut against each other, and the vertical distance between the second step surface 203 and the first step surface 100 gradually increases along the direction away from the center of the heat dissipation body 2, such as... Figure 5 As shown, this is to provide buffer space for the heat dissipation body 2 and heat dissipation shell 1 when they deform, thereby increasing the stability of the assembly.

[0054] In an optional embodiment, the luminaire further includes a sleeve 3 mounted on the bottom end of the heat sink body 2, and a flexible mounting angle 4 is mounted on the sleeve 3. The sleeve 3 and the flexible mounting angle 4 on the sleeve 3 serve to secure the luminaire to the ceiling or suspended ceiling.

[0055] In an optional embodiment where the flexible mounting angle 4 is mounted on the sleeve 3, a mounting opening 30 is provided on the side wall of the sleeve 3, and a mounting groove 31 communicating with the mounting opening 30 is provided on the inner wall of the sleeve 3; the flexible mounting angle 4 is provided with a mounting part, which includes a bent and connected insert piece 40 and a mounting piece 41; the insert piece 40 is inserted into the mounting opening 30, and the mounting piece 41 is inserted into the mounting groove and fits between the mounting groove 31 and the heat dissipation body 2. Figure 13 The aforementioned flexible mounting angle 4 is shaped like a "Z", and the mounting piece is used to... Figure 11 and Figure 12 The mounting opening 30 shown is fitted together to limit the elastic mounting angle 4 in the circumferential direction, while the mounting piece 41 is pressed and squeezed by the bottom of the mounting groove 31 and the outer wall of the heat dissipation body 2 and is limited in the radial direction.

[0056] The flexible mounting angle 4 can be made of metal, which can not only meet the required elasticity but also increase the heat dissipation effect.

[0057] Furthermore, the fact that the two ends of the mounting plate along the circumferential direction abut against the two side walls of the groove along the circumferential direction can effectively increase the stability of the mounting plate in the groove.

[0058] Based on the installation requirements of the lighting fixtures, the number of flexible mounting angles 4 can be set to two, such as... Figure 1 and Figure 6 As shown; the number of flexible mounting angles 4 can also be set to two or more, and they are evenly arranged along the circumference of the heat dissipation body 2 to increase the stability of the lamp after installation.

[0059] In an optional embodiment where the sleeve 3 is connected to the heat dissipation body 2, the inner side of the sleeve 3 is provided with an internal thread, such as... Figure 11 and Figure 12As shown, the outer side of the heat dissipation body 2 is provided with external threads, such as... Figure 9 and Figure 10 As shown. The sleeve 3 is threaded onto the outside of the heat sink body 2, and during the threading process, the elastic mounting angle 4 is pressed and secured between the sleeve 3 and the heat sink body 2.

[0060] In an optional embodiment, the bottom end face of the heat sink 1 is a first annular surface 12, and the top end face of the sleeve 3 is a second annular surface 33; the first annular surface 12 and the second annular surface 33 are inclined outwards in opposite directions along the radial direction of the heat sink body 2. The first annular surface 12 and the second annular surface 33 form a "V" shaped structure at the joint, such as... Figure 4 and Figure 5 As shown, this not only helps to reduce the thickness of the heat dissipation body 2 and the heat dissipation shell 1 at the joint, thus increasing the heat dissipation effect, but also helps to increase the visibility of the lamp. At the same time, it provides a certain buffer space for the relative displacement of the heat dissipation body 2 and the heat dissipation shell 1 after being heated.

[0061] In an optional embodiment, the bottom of the flexible mounting angle 4 is provided with a snap-fit ​​groove 42. When it is necessary to install a light fixture, the flexible mounting angle 4 needs to be hung on the ceiling or suspended ceiling. The bottom of the flexible mounting angle 4 is used to snap onto the ceiling or suspended ceiling or connect to it in other ways. The snap-fit ​​groove 42 increases the contact area between the flexible mounting angle 4 and the ceiling or suspended ceiling at the snap-fit ​​point, thereby increasing the stability of the snap-fit.

[0062] Furthermore, the number of snap-fit ​​slots 42 can be set to multiple and arranged along the length direction of the elastic mounting angle 4 to form a shape such as Figure 13 The serrated shape shown above helps to increase the number of points where the flexible installation angle 4 can be engaged with the ceiling or suspended ceiling, thus increasing the flexibility of installation.

[0063] In an optional embodiment, a face ring 31 is further provided at the bottom of the sleeve 3, such as... Figure 11 As shown. The face ring 31 is used to encapsulate lighting components such as lamp beads within the heat dissipation body 2 and the sleeve 3, thereby increasing the appearance quality.

[0064] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0065] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
