Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and specifically relates to a lamp. Background Technology

[0002] Currently, lighting fixtures play a crucial role in illumination, whether in indoor home environments or outdoor public areas.

[0003] However, with the development of technology, people's requirements for lighting fixtures are no longer limited to meeting basic lighting needs; they also place higher demands on the ease of assembly. Traditional lighting fixtures typically consist of a mounting base, a lamp body, and a connecting rod. The lamp body is connected to the mounting base via the connecting rod, and the mounting base is installed on a mounting foundation. However, the ease of assembly between the lamp body and the connecting rod in traditional lighting fixtures is often poor.

[0004] Therefore, how to improve the ease of assembly between the lamp body and the connecting rod of the lamp has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a lamp that can solve the problem of poor applicability of lamps in related technologies.

[0006] This application provides a lamp, including: a mounting base, a lamp body, and a connecting rod;

[0007] The lamp body includes a housing, and the inner wall of the housing is provided with a guide post extending along its axial direction. The guide post is provided with a through groove, and the through groove extends along the axial direction of the housing.

[0008] The connecting rod is connected to the mounting base. The connecting rod is provided with a connecting frame. A portion of the connecting frame is located in the through groove and slides with the through groove along the axial direction of the outer shell. The connecting frame is provided with a mating protrusion. The mating protrusion is supported on one end of the guide post and is connected to the guide post.

[0009] When assembling the lamp body and connecting rod of traditional lamps, the lack of a positioning benchmark requires the use of additional tools to determine the specific installation position of the connecting rod, which results in poor assembly convenience between the lamp body and the connecting rod.

[0010] In this embodiment, the inner wall of the lamp body's outer shell is provided with a guide post extending axially. The guide post has a through groove extending axially along the outer shell. The connecting rod has a connecting bracket, a portion of which is located within the through groove and slides with the through groove axially along the outer shell. The connecting bracket also has a mating protrusion supported at one end of the guide post and connected to the guide post. With this configuration, placing a portion of the connecting bracket within the through groove allows for the positioning of the connecting rod in the circumferential direction of the lamp body. Simultaneously, when the mating protrusion is supported at one end of the guide post, the axial position of the connecting rod in the lamp body is determined. This means that the axial and circumferential positions of the connecting rod in the lamp body can be determined without additional tools, thus enabling the precise installation of the connecting rod. This improves the ease of assembling the lamp body and the connecting rod. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The lighting fixtures provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0033] Please refer to Figures 1 to 12 As shown in the figure, this application provides a lamp, including: a mounting base, a lamp body 300 and a connecting rod 510.

[0034] The lamp body 300 includes a housing 310. The inner wall of the housing 310 is provided with a guide post 311 extending axially therefrom. The guide post 311 has a through groove 3111 extending axially along the housing 310. The axial direction of the housing 310 is, for example, [missing information]. Figure 11 The direction indicated by arrow A in the diagram, and the axial direction of the housing 310, for example, is the axial direction of the lamp body 300.

[0035] The connecting rod 510 is connected to the mounting base. The connecting rod 510 is provided with a connecting bracket 320. A portion of the connecting bracket 320 is located in the through groove 3111 and slides with the through groove 3111 along the axial direction of the housing 310. Optionally, refer to Figure 7 and Figure 8 As shown, the connecting frame 320 is provided with a guide protrusion 322, which slides in conjunction with the through groove 3111 along the axial direction of the outer shell 310. The connecting frame 320 is also provided with a mating protrusion 321, which is supported on one end of the guide post 311 and connected to the guide post 311.

[0036] When assembling the lamp body 300 and the connecting rod 510 of a traditional lamp, the lack of a positioning reference necessitates the use of additional tools to determine the specific installation position of the connecting rod 510, resulting in poor assembly convenience between the lamp body 300 and the connecting rod 510.

[0037] In this embodiment, the inner wall of the outer shell 310 of the lamp body 300 is provided with a guide post 311 extending axially therefrom. The guide post 311 is provided with a through groove 3111, which extends axially along the outer shell 310. The connecting rod 510 is provided with a connecting bracket 320. A portion of the connecting bracket 320 is located within the through groove 3111 and slides with the through groove 3111 along the axial direction of the outer shell 310. The connecting bracket 320 is provided with a mating protrusion 321, which is supported on one end of the guide post 311 and connected to the guide post 311. In this configuration, placing a portion of the connecting bracket 320 within the through groove 3111 can position the connecting rod 510 in the circumferential direction of the lamp body 300. Simultaneously, when the mating protrusion 321 is supported on one end of the guide post 311, the axial position of the connecting rod 510 in the lamp body 300 is determined accordingly. This means that the axial and circumferential installation positions of the connecting rod 510 on the lamp body 300 can be determined without the need for additional tools, and the specific installation position of the connecting rod 510 can be determined accordingly. As a result, the assembly of the lamp body 300 and the connecting rod 510 is more convenient.

[0038] In one optional embodiment, the lamp fixture may further include a first threaded component, one end of which passes through the mating protrusion 321 and extends into the through groove 3111. The first threaded component is threadedly connected to the wall of the through groove 3111, so that the connecting bracket 320 is detachably connected to the outer shell 310 of the lamp body 300. This arrangement makes the assembly and disassembly of the connecting bracket 320 more convenient, thereby reducing the difficulty of assembling and disassembling the connecting bracket 320. Furthermore, in this embodiment, the first threaded component is directly threadedly connected to the wall of the through groove 3111, thereby achieving the connection between the connecting bracket 320 and the outer shell 310 of the lamp body 300. In this configuration, the through groove 3111 serves both to position the connecting bracket 320 and to connect the connecting bracket 320 to the lamp body 300. This eliminates the need for additional structures to connect the connecting bracket 320 to the lamp body 300, thus simplifying the structure of the lamp fixture.

[0039] In one alternative embodiment, reference is made to... Figure 1 and Figure 7As shown, the connecting frame 320 is provided with a mating groove 323, and a part of the connecting rod 510 is located in the mating groove 323. The two opposite groove walls of the mating groove 323 are provided with a first opening 324 and a second opening 325. The lamp body 300 also includes a second threaded component 331 and a second nut 332. One end of the second threaded component 331 passes through the first opening 324, the connecting rod 510 and the second opening 325 in sequence, and is fastened by the second nut 332 to mount the connecting frame 320 on the connecting rod 510. In this configuration, the connecting frame 320 and the connecting rod 510 are detachably connected by the second threaded component 331 and the second nut 332. This makes it easier to assemble and disassemble the connecting frame 320 and the connecting rod 510, and facilitates the individual replacement of the connecting frame 320 and the connecting rod 510.

[0040] In another embodiment, reference Figure 1 As shown, the mounting base is a fixed base 100, which is used to fix the light fixture to the mounting surface to meet the installation requirements of fixing the light fixture to the mounting surface. Optionally, the fixed base 100 can be wall-mounted to the mounting surface or ceiling-mounted to the mounting surface. Specifically, when the fixed base 100 is ceiling-mounted to the mounting surface, the mounting surface is, for example, the surface of the ceiling.

[0041] In another embodiment, reference Figure 1 As shown, the mounting base can also be a track base 200. The track base 200 has at least two conductive parts 210, each conductive part 210 being disposed in a different guide groove of the mounting rail. Each conductive part 210 is used to slide and make conductive contact with the corresponding guide groove along the length direction of the mounting rail. With this arrangement, the lamp can be used in installation scenarios where the mounting rail is installed.

[0042] It should be noted that mounting surface installation and mounting rail installation are two different installation scenarios. In the case of mounting surface installation, the position of the lamp is fixed, while in the case of mounting rail installation, the lamp can slide along the length of the mounting rail. Furthermore, in this embodiment, the specific number of conductive parts 210 is not limited. The number of conductive parts 210 mainly depends on the number of guide grooves in the mounting rail, and can be designed according to actual needs. Optionally, the conductive parts 210 and guide grooves may correspond one-to-one, and the conductive parts 210 may be, for example, conductive sheets.

[0043] Optionally, refer to Figure 2As shown, the track base 200 may have two, three, four, or six conductive parts 210. Specifically, when the track base 200 has two conductive parts 210, it is used to accommodate two-wire mounting rails; when it has three conductive parts 210, it is used to accommodate three-wire mounting rails; when it has four conductive parts 210, it is used to accommodate four-wire mounting rails; and when it has six conductive parts 210, it is used to accommodate six-wire mounting rails.

[0044] Specifically, two-wire, three-wire, four-wire, and six-wire mounting rails all belong to the mounting rails mentioned above. The difference lies in that a two-wire mounting rail includes two guide slots, a three-wire mounting rail includes three guide slots, a four-wire mounting rail includes four guide slots, and a six-wire mounting rail includes six guide slots. Furthermore, the different guide slots on the mounting rail are used for electrical connections to different parts of the power cord. For example, taking a two-wire mounting rail as an example, the two guide slots are used for electrical connections to the live wire and the neutral wire of the external power cord, respectively.

[0045] In another embodiment, reference Figure 1 As shown, the lamp body 300 also includes a light source module 350, which is located within the housing 310. The lamp also includes a circuit board 400, which is located within a mounting base and is electrically connected to the light source module 350. The circuit board 400 can be either a non-isolated circuit board 400a or an isolated circuit board 400b. When the circuit board 400 is a non-isolated circuit board 400a, its size is smaller, thus meeting the installation requirements of smaller spaces. When the circuit board 400 is an isolated circuit board 400b, its safety is better, reducing the probability of safety accidents.

[0046] Optionally, the non-isolated circuit board 400a and the isolated circuit board 400b may have the same or different functions, specifically referring to the differences in the performance of the circuit boards 400 in adjusting the color temperature and brightness of the light emitted by the lamp body 300. Taking the isolated circuit board 400b as an example, it may only have the function of changing the brightness of the light emitted by the lamp body 300, or only have the function of changing the color temperature of the light emitted by the lamp body 300, or it may have both the functions of changing the brightness and the color temperature of the light emitted by the lamp body 300. Specifically, the isolated circuit board 400b may be, for example, a Bluetooth isolated circuit board or a color temperature adjustable isolated circuit board to meet the corresponding control requirements.

[0047] Alternatively, when the mounting base is a track base 200, the circuit board 400 is connected to the conductive part 210 on the track base 200, thereby allowing the circuit board 400 to be electrically connected to the external power line in sequence through the conductive part 210 and the mounting rail. When the mounting base is a fixed base 100, the circuit board 400 is directly electrically connected to the external power line, for example.

[0048] In another embodiment, reference Figures 1 to 3 As shown, the mounting base has a housing structure. The mounting base includes a detachably connected first sub-housing 221 and a second sub-housing 222. The first sub-housing 221 is located on the side of the second sub-housing 222 facing away from the lamp body 300, and the second sub-housing 222 is connected to the connecting rod 510. In this arrangement, the first sub-housing 221 and the second sub-housing 222 are arranged sequentially along the axial direction of the lamp body 300, thus meeting the user's need to assemble and disassemble the mounting base along the axial direction of the lamp body 300. Furthermore, the detachable connection of the first sub-housing 221 and the second sub-housing 222 means that if either the first sub-housing 221 or the second sub-housing 222 is damaged, only the damaged one needs to be replaced, without having to replace both the first sub-housing 221 and the second sub-housing 222, thereby reducing waste.

[0049] Optionally, the first sub-housing 221 and the second sub-housing 222 are detachably connected, for example, by a third threaded member 600, which is, for example, a screw.

[0050] Specifically, Figure 1 There are two first sub-shells 221 and one second sub-shell 222. One of the first sub-shells 221 and the second sub-shell 222 can be matched to obtain, for example, the two-line mounting rail mentioned above. The other first sub-shell 221 and the second sub-shell 222 can be matched to obtain, for example, the three-line mounting rail mentioned above. Figure 1 The difference between the two first sub-shells 221 is that the first sub-shell 221 corresponding to the two-wire mounting rail has two clearance holes, and the first sub-shell 221 corresponding to the three-wire mounting rail has three clearance holes. The clearance holes correspond one-to-one with the conductive parts 210 mentioned above. One end of each conductive part 210 passes through the corresponding clearance hole and cooperates with the corresponding guide groove of the corresponding mounting rail.

[0051] In another embodiment, reference Figure 1 and Figure 4As shown, the mounting base has a housing structure. The mounting base includes a detachably connected third sub-housing 223 and a fourth sub-housing 224, which are arranged side-by-side on the same side of the lamp body 300 and both are connected to the connecting rod 510. In this arrangement, the third sub-housing 223 and the fourth sub-housing 224 are arranged sequentially along a direction perpendicular to the axial direction of the lamp body 300, thus meeting the user's need to assemble and disassemble the mounting base along this direction. Furthermore, the detachable connection of the third sub-housing 223 and the fourth sub-housing 224 means that if one of them is damaged, only the damaged one needs to be replaced, eliminating the need to replace both sub-housing 223 and the fourth sub-housing 224, thereby reducing waste.

[0052] In one specific implementation, the mounting base is a housing structure, such as the fixed base 100 or the track base 200 mentioned above, and the inner cavity of the mounting base is used to accommodate the electronic components of the lamp, such as the circuit board 400 mentioned above.

[0053] In another embodiment, reference Figure 5 and Figure 9 As shown, the mounting base includes the first sub-housing 221 and the second sub-housing 222 mentioned above. One end of the connecting rod 510 is provided with a connecting bracket 320, and the other end is provided with a connecting portion 513. A portion of the connecting portion 513 extends into the second sub-housing 222 and is detachably connected to a locking member 520. The connecting rod 510 and the locking member 520 abut against opposite sides of the second sub-housing 222 to lock the connecting rod 510, thereby connecting the connecting rod 510 to the second sub-housing 222. For ease of distinction, the connecting rod 510 in this embodiment is defined as the first connecting rod 510a.

[0054] In this embodiment, when the locking member 520 is removed, the connecting rod 510 can rotate around its own axis without restriction. The connecting rod 510 can be rotated around its axis more easily, thereby making it easier to adjust the mounting angle of the connecting rod 510 relative to the mounting base.

[0055] Optionally, the locking element 520 may be, for example, a nut, which is threaded onto the connecting portion 513. This facilitates the adjustment of the force between the locking element 520 and the second sub-housing 222, reducing the possibility of damage to the second sub-housing 222 due to excessive force.

[0056] In another embodiment, reference Figure 4 and Figure 6As shown, the mounting base includes a third sub-housing 223 and a fourth sub-housing 224. One end of the connecting rod 510 is provided with a connecting bracket 320, and the other end is provided with a circumferential annular groove 512. A portion of the third sub-housing 223 and a portion of the fourth sub-housing 224 are located in the annular groove 512, and the third sub-housing 223 and the fourth sub-housing 224 together clamp the connecting rod 510 to lock the connecting rod 510, thereby connecting the connecting rod 510 to the third sub-housing 223 and the fourth sub-housing 224. For ease of distinction, the connecting rod 510 in this embodiment is defined as the second connecting rod 510b.

[0057] In this embodiment, no additional components are required. The connecting rod 510 can be locked by the clamping force between the third sub-housing 223 and the fourth sub-housing 224, thereby simplifying the structure of the lamp.

[0058] In actual use, external force needs to overcome the frictional force exerted on the connecting rod 510 by the third sub-shell 223 and the fourth sub-shell 224 in order for the connecting rod 510 to rotate around its axis.

[0059] In another embodiment, the connecting rod 510 is provided with a limiting block 511, the mounting base is provided with a mating block 230, the connecting rod 510 is rotatably connected to the mounting base, the rotation axis of the connecting rod 510 is, for example, its own axis, and the mating block 230 is located on the rotation path of the limiting block 511.

[0060] In this embodiment, by the cooperation of the limiting block 511 and the mating block 230, the connecting rod 510 can be prevented from rotating multiple times relative to the mounting base, thereby reducing the friction between the connecting rod 510 and the mounting base and extending the service life of the connecting rod 510.

[0061] Furthermore, the connecting rod 510 may have a wiring channel, and the lamp body 300 may also include a cable. One end of the cable passes through the wiring channel and is electrically connected to the circuit board 400 mentioned above, so that the circuit board 400 controls the operation of the lamp body 300 and enables the lamp body 300 to be electrically connected to an external power supply. In this configuration, the cable is hidden in the wiring channel, and the cable is less likely to interfere with the operation of other components. In addition, in this embodiment, the connecting rod 510 can only rotate one turn. This prevents the cable from getting tangled due to multiple turns of the connecting rod 510. With this configuration, the probability of cable tangling is low.

[0062] Optionally, the mounting base is, for example, a fixed base 100, and the mounting base includes, for example, the first sub-housing 221 and the second sub-housing 222 mentioned above. The second sub-housing 222 is provided with a mating block 230, the connecting rod 510 is the first connecting rod 510a mentioned above, and the limiting block 511 is, for example, located inside the second sub-housing 222.

[0063] Optionally, refer to Figure 3 and Figure 5 As shown, the mounting base is, for example, a track base 200, and the mounting base includes, for example, the first sub-shell 221 and the second sub-shell 222 mentioned above. The second sub-shell 222 is provided with a mating block 230, the connecting rod 510 is the first connecting rod 510a mentioned above, and the limiting block 511 is, for example, located inside the second sub-shell 222.

[0064] Optionally, refer to Figure 4 and Figure 6 As shown, the mounting base is, for example, a track base 200, and the mounting base includes, for example, the third sub-housing 223 and the fourth sub-housing 224 mentioned above. The mating block 230 is located outside the mounting base, the connecting rod 510 is the second connecting rod 510b mentioned above, and the limiting block 511 is located outside the mounting base.

[0065] In other embodiments, the connecting rod 510 may not have a limiting block 511, and correspondingly, the mounting base may not have a mating block 230. In this case, the connecting rod 510 can rotate any number of turns relative to the mounting base.

[0066] In another embodiment, reference Figure 1 As shown, the lamp body 300 also includes a light source module 350, which is located within the housing 310. The light source module 350 can be either a non-isolated light source module 350a or an isolated light source module 350b. When the light source module 350 is a non-isolated light source module 350a, its size is smaller, thus meeting the installation requirements of smaller spaces. When the light source module 350 is an isolated light source module 350b, its safety is better, reducing the probability of safety accidents.

[0067] Optionally, the optical parameters of the non-isolated light source module 350a and the isolated light source module 350b may differ, for example. Specifically, the difference here refers to, for example, differences in brightness and color temperature parameters between the non-isolated light source module 350a and the isolated light source module 350b.

[0068] Optionally, the isolated light source module 350b is, for example, an aluminum substrate light source module, and the non-isolated light source module 350a is, for example, a ceramic substrate light source module.

[0069] Specifically, when the light source module 350 is a non-isolated light source module 350a, the lamp body 300 includes, for example, the non-isolated circuit board 400a mentioned above. The non-isolated light source module 350a and the non-isolated circuit board 400a are electrically connected and used together. When the light source module 350 is an isolated light source module 350b, the lamp body 300 includes, for example, the isolated circuit board 400b mentioned above. The isolated light source module 350b and the isolated circuit board 400b are electrically connected and used together.

[0070] In another embodiment, reference Figure 1 As shown, the lamp body 300 also includes a light source module 350, which is located inside the housing 310. The lamp body 300 also includes an optical lens 381, which is located inside the housing 310 and on the light-emitting side of the light source module 350. The optical lens 381 is used to change the emission angle of the light emitted from the light source module 350 to obtain the desired light spot, thereby providing the user with the desired lighting effect.

[0071] In another embodiment, reference Figure 1 As shown, the lamp body 300 also includes a light source module 350, which is located inside the housing 310. The lamp body 300 also includes a metal reflective ring 382, ​​which is located inside the housing 310 and on the light-emitting side of the light source module 350. The metal reflective ring 382 is used to change the emission angle of the light emitted from the light source module 350 to obtain the desired light spot, thereby providing the user with the desired lighting effect.

[0072] It should be noted that both the metal reflective ring 382 and the optical lens 381 are used to change the emission angle of the light emitted from the light source module 350, and the lamp only includes one of them.

[0073] In another embodiment, the lamp body 300 includes an optical lens 381, and the lamp body 300 also includes a mounting bracket 360 and a first retaining ring 370a. The mounting bracket 360 and the first retaining ring 370a are both located inside the housing 310. The mounting bracket 360 is connected to the housing 310 and is located on the light-emitting side of the light source module 350. The first retaining ring 370a and the mounting bracket 360 together hold the optical lens 381. The first retaining ring 370a is located on the light-emitting side of the optical lens 381, and the inner wall of the housing 310 is provided with a snap-fit ​​part, which snaps into the first retaining ring 370a.

[0074] In this embodiment, the first retaining ring 370a engages with the retaining part on the housing 310. This engagement facilitates the installation and removal of the first retaining ring 370a.
