It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model 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, the 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.

[0038] The lighting fixture provided by the present invention will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0039] like Figures 1 to 7 As shown, an embodiment of this utility model provides a lighting fixture. Optionally, the lighting fixture in this embodiment can be a spotlight, but it can also be other types of lighting fixtures. This application embodiment does not make specific limitations in this regard. The lighting fixture includes a first lamp body 100 and a second lamp body 200, which are detachably connected. The first lamp body 100 has a light-emitting surface to emit light, and the second lamp body 200 has a light-transmitting hole 210. The light-emitting surface of the first lamp body 100 faces the light-transmitting hole 210 of the second lamp body 200. The light emitted by the first lamp body 100 passes through the light-transmitting hole 210 and exits the lighting fixture, thereby propagating to the external environment to achieve a lighting effect. The second lamp body 200 can be used to connect to a mounting base. Optionally, the mounting base can be a ceiling, a bracket, etc. This application embodiment does not make specific limitations in this regard.

[0040] The first lamp body 100 has a first lamp tube 130 including a sleeved annular outer tube 132 and an annular inner tube 131. The outer annular surface of the annular inner tube 131 is provided with a first snap-fit ​​portion 131a. The second lamp body 200 has an annular structure. The inner annular surface of the annular structure forms a light-transmitting hole 210. The second lamp body 200 is provided with a second snap-fit ​​portion 221. At least a portion of the second snap-fit ​​portion 221 is inserted between the annular outer tube 132 and the annular inner tube 131. The second snap-fit ​​portion 221 and the first snap-fit ​​portion 131a are positioned and engaged in the axial direction of the annular inner tube 131 so that the second lamp body 200 and the first lamp body 100 can be detachably connected.

[0041] In the lighting fixture provided by this utility model, when it is necessary to adjust the lighting effect or the shape of the fixture during use, the second latching part 221 of the second lamp body 200 is disengaged from the first latching part 131a of the first lamp body 100, thereby disassembling and separating the second lamp body 200 from the first lamp body 100 for replacement of the first lamp body 100. After replacing the first lamp body 100, at least a portion of the second latching part 221 of the second lamp body 200 is inserted between the annular outer cylinder 132 and the annular inner cylinder 131 of the first lamp body 100, so that the second latching part 221 and the first latching part 131a are positioned and engaged axially in the annular inner cylinder 131, thereby detachably connecting the first lamp body 100 and the second lamp body 200 to form the desired lighting effect or fixture shape, thus expanding the applicability of the lighting fixture. Therefore, the technical solution disclosed in this utility model can solve the problem of the current lighting fixtures having a relatively limited application scenario.

[0042] In an optional embodiment, the first lamp body 100 includes a heat dissipation module 110 and a photoelectric module 120. The heat dissipation module 110 and the photoelectric module 120 are detachably connected, and the photoelectric module 120 is detachably connected to the second lamp body 200. During the use of this lamp, when it is necessary to adjust the heat dissipation module 110 and / or the photoelectric module 120, the first lamp body 100 and the second lamp body 200 can be separated first, and then the heat dissipation module 110 and the photoelectric module 120 can be separated to replace the heat dissipation module 110 with a different power or shape, and / or to replace the light-emitting element of the photoelectric module 120 with a different power or color of light, thereby meeting actual usage requirements. Of course, the heat dissipation module 110 and the photoelectric module 120 can also be an integrated structure; when it is necessary to adjust the heat dissipation module 110 and / or the photoelectric module 120, the first lamp body 100 can be replaced entirely.

[0043] In a further optional embodiment, the heat dissipation module 110 includes a second lamp tube 111, a heat sink 112, and a first fastener 113. The heat sink 112 is disposed outside the second lamp tube 111. One end of the first fastener 113 passes through the heat sink 112 and is detachably connected to the second lamp tube 111. The photoelectric module 120 is detachably connected to the second lamp tube 111, with a portion of the photoelectric module 120 located within the receiving cavity of the second lamp tube 111. In this solution, during the use of the lamp, the heat sink 112 with different power and shape can be replaced according to actual usage needs. Simultaneously, the second lamp tube 111 with different shapes can be replaced according to actual usage needs, thereby changing the appearance of the lamp to achieve the desired visual effect. Of course, the heat sink 112 and the second lamp tube 111 can also be connected in a non-detachable manner.

[0044] Optionally, one of the second lamp housing 111 and the heat sink 112 is provided with a positioning post 111a, and the other is provided with a positioning hole 112a, with the positioning post 111a and the positioning hole 112a engaging in a positioning fit. During the assembly of the heat sink module 110, the heat sink 112 and the second lamp housing 111 can be pre-fixed by engaging the positioning post 111a and the positioning hole 112a. Then, the heat sink 112 and the second lamp housing 111 are detachably connected using the first fastener 113 for fixation. This prevents the heat sink 112 and the second lamp housing 111 from shifting during the fixing process, thereby improving the assembly efficiency of the heat sink module 110. Alternatively, the positioning post 111a and the positioning hole 112a can be omitted.

[0045] Optionally, the heat dissipation module 110 also includes a stacked pressure cover 114 and a protective cover 115. During the assembly of the heat dissipation module 110, one end of the first fastener 113 passes through the pressure cover 114 and the heat sink 112 and is threadedly connected to the second lamp tube 111 so that the pressure cover 114 presses the heat sink 112. The protective cover 115 is placed on the pressure cover 114 and is located in the receiving groove of the pressure cover 114. The pressure cover 114 covers the first fastener 113, thereby preventing the first fastener 113 from rusting and also achieving an aesthetic effect.

[0046] Optionally, the heat sink 112 can be formed by stacking several heat sink fins, or it can be other types of heat sink structures. This application embodiment does not impose specific limitations on this.

[0047] In a further optional embodiment, the photoelectric module 120 includes a light source assembly 121, a light distribution assembly 122, and a first lamp tube 130. Parts of the light source assembly 121 and the light distribution assembly 122 are both disposed within the receiving cavity of the second lamp tube 111. The light source assembly 121 and the light distribution assembly 122 are detachably connected. The first lamp tube 130 is detachably connected to the light source assembly 121. Another part of the light distribution assembly 122 is disposed within the receiving cavity of the first lamp tube 130. The light-emitting surface of the first lamp body 100 is disposed on the light distribution assembly 122. When it is necessary to replace the light source component 121 with one of different power or model, firstly, the first lamp tube 130 is separated from the light source component 121, and the light distribution component 122 is separated from the light source component 121. Then, the light source component 121 is separated from the second lamp tube 111. After replacing the light source component 121, during the assembly of the photoelectric module 120, firstly, the light source component 121 is installed onto the second lamp tube 111 of the heat dissipation module 110, then the light distribution component 122 is installed onto the light source component 121, and finally, the first lamp tube 130 is detachably connected to the light source component 121. In other words, this solution disassembles the photoelectric module 120 into the light source component 121, the light distribution component 122, and the first lamp tube 130 to form a modular structure, which helps to improve the assembly and disassembly efficiency of the photoelectric module 120.

[0048] In another optional embodiment, the photoelectric module 120 includes a second lamp tube 111, a light source assembly 121, a light distribution assembly 122, and a first lamp tube 130. Parts of the light source assembly 121 and the light distribution assembly 122 are disposed within the receiving cavity of the second lamp tube 111. The light source assembly 121 is detachably connected to the second lamp tube 111, and the first lamp tube 130 is detachably connected to the light source assembly 121. Another part of the light distribution assembly 122 is disposed within the receiving cavity of the first lamp tube 130, and the light-emitting surface is disposed on the light distribution assembly 122. The heat dissipation module 110 includes a heat sink 112 disposed outside the second lamp tube 111 and detachably connected to the second lamp tube 111. Optionally, the heat dissipation module 110 further includes a first fastener 113, one end of which passes through the heat sink 112 and is threadedly connected to the second lamp tube 111.

[0049] When the heat sink 112 needs to be replaced during the use of the lamp, it can be directly detached from the photoelectric module 120. Different power and shape heat sinks 112 can be replaced according to actual usage requirements. During the assembly of the first lamp body 100, the light source assembly 121 is first installed onto the second lamp tube 111, then the light distribution assembly 122 is installed onto the light source assembly 121, and the first lamp tube 130 is detachably connected to the light source assembly 121. Finally, the heat sink 112 is installed onto the second lamp tube 111. This configuration makes replacing the heat sink 112 more convenient, eliminating the need to disassemble the light source assembly 121 and the light distribution assembly 122.

[0050] Optionally, in any of the above embodiments, the light source assembly 121 includes a light source plate 121a, an annular adapter plate 121b, an annular fixing member 121c, and a second fastener 121d. The annular adapter plate 121b is disposed in a receiving groove on the end face of the annular fixing member 121c, the receiving groove being located on the end face of the annular fixing member 121c away from the second lamp body 200. The light source plate 121a is stacked on the side of the annular adapter plate 121b away from the second lamp body 200. Optionally, the light source plate 121a and the annular adapter plate 121b can be fixedly connected by welding. Optionally, the light source plate 121a is located on the side of the annular adapter plate 121b away from the second lamp body 200, and the light source on the light source plate 121a faces the through hole of the annular adapter plate 121b to allow light to pass through.

[0051] The outer peripheral surface of the annular fastener 121c is provided with a wire-passing protrusion 121c1 and a light-blocking flange 121c2 arranged at intervals along its axial direction. The wire-passing protrusion 121c1 is located at one end of the annular fastener 121c near the annular adapter plate 121b. The wire-passing protrusion 121c1 has a sleeve structure. Part of the end face of the sleeve structure is connected to the outer peripheral surface of the annular fastener 121c. One end of the cable is electrically connected to the annular adapter plate 121b, and the other end of the cable passes through the wire-passing protrusion 121c1 and the second lamp tube 111 in sequence and extends to the outside of the lamp. Because a certain gap needs to be reserved between the wire threading protrusion 121c1 and the annular adapter plate 121b to allow the cable to enter the wire threading hole of the wire threading protrusion 121c1, this gap will cause a small amount of light leakage. Based on this, a light-blocking flange 121c2 is provided on the outer peripheral surface of the annular fixing member 121c. The light-blocking flange 121c2 is located at the end of the annular fixing member 121c near the second lamp body 200. The light-blocking flange 121c2 is used to block the light leakage between the wire threading protrusion 121c1 and the annular adapter plate 121b, preventing this part of the light from shining out of the lamp, thereby reducing the stray light of the lamp and improving the lighting effect of the lamp.

[0052] Optionally, one end of the second fastener 121d passes through the annular fastener 121c and is detachably connected to the second lamp tube 111.

[0053] Optionally, the outer peripheral surface of the annular fastener 121c is also provided with a connecting flange 121c3. The connecting flange 121c3 is located at one end of the annular fastener 121c near the annular adapter plate 121b. The connecting flange 121c3 has an arc-shaped structure. The wire-passing protrusion 121c1 is located between the two ends of the connecting flange 121c3. The connecting flange 121c3 is provided with a connecting through hole. The light-blocking flange 121c2 is provided with a clearance opening. One end of the second fastener 121d passes through the clearance opening and the connecting through hole in sequence and is threadedly connected to the second lamp tube 111.

[0054] Optionally, the light distribution assembly 122 includes a first annular reflector 122a and a light guide 122b. A portion of the first annular reflector 122a is disposed within the receiving space of the annular fixing member 121c. Optionally, the first annular reflector 122a and the annular fixing member 121c can be fixed by an interference fit. The other portion of the first annular reflector 122a and the light guide 122b are both disposed within the receiving space of the first lamp tube 130. Optionally, the first annular reflector 122a and the first lamp tube 130 can be fixed by an interference fit. The light guide 122b is located on the side of the first annular reflector 122a closer to the second lamp body 200. The light-emitting surface of the first lamp body 100 is disposed on the light guide 122b. Optionally, the light guide 122b can be a diffuser, which has the function of adjusting the angle, direction and uniformity of light, and can make the light more uniform, soft and comfortable. The first lamp tube 130 is detachably connected to the annular fixing member 121c via a third fastener 300. Optionally, the connecting flange 121c3 is also provided with a threaded connection hole, and one end of the third fastener 300 passes through the threaded connection hole between the first lamp tube 130 and the annular fixing member 121c for threaded connection. In this scheme, the first annular reflector 122a is clamped between the annular fixing member 121c and the first lamp tube 130, which helps to improve the stability of the first annular reflector 122a and the connection stability between the light source assembly 121 and the light distribution assembly 122. Of course, the third fastener 300 can also be omitted, and the first annular reflector 122a and the annular fixing member 121c, as well as the first annular reflector 122a and the first lamp tube 130, can also be fixed by friction, and then the first lamp tube 130 and the annular fixing member 121c of the light source assembly 121 are connected by a snap-fit.

[0055] Optionally, the first snap-fit ​​portion 131a and the second snap-fit ​​portion 221 can engage through their own deformation; or, in an optional embodiment, the first snap-fit ​​portion 131a includes a connected first snap-fit ​​segment 131a1 and a limiting segment 131a2, the first snap-fit ​​segment 131a1 is bent relative to the limiting segment 131a2, that is, the first snap-fit ​​portion 131a has an L-shaped structure, and the second snap-fit ​​portion 221 can engage with the limiting segment 131a2 of the first snap-fit ​​portion 131a in the circumferential direction of the annular inner cylinder 131 to prevent the rotating ring 220 from continuing to rotate.

In this case, the connection area between the second snap-fit ​​portion 221 and the annular body of the rotating ring 220 is relatively large, so that the structural strength of the connection between the two is greater. Of course, the second snap-fit ​​portion 221 can also be located on the end face of the rotating ring 220. The second snap-fit ​​section 221b is bent relative to the connecting section 221a, that is, the second snap-fit ​​portion 221 has an L-shaped structure. The second snap-fit ​​section 221b and the first snap-fit ​​section 131a1 are positioned and engaged axially in the annular inner cylinder 131, so that the rotating ring 220 and the first lamp tube 130 can be detachably connected. The face ring assembly 230 can be used to connect the mounting base.

[0056] During the assembly of the first lamp body 200 and the first lamp body 100, the second snap-fit ​​portion 221 of the rotating ring 220 is inserted into the outer side of the annular inner cylinder 131 of the first lamp tube 130. Then, the rotating ring 220 is rotated so that the second snap-fit ​​segment 221b of the second snap-fit ​​portion 221 is opposite to the first snap-fit ​​segment 131a1 of the first snap-fit ​​portion 131a. Rotation stops after the limiting segment 131a2 of the second snap-fit ​​portion 221 and the first snap-fit ​​portion 131a are in circumferential upper limit engagement with the annular inner cylinder 131. At this time, the second snap-fit ​​portion 221 and the first snap-fit ​​portion 131a are positioned and engaged in the axial direction of the annular inner cylinder 131, so that the rotating ring 220 and the second lamp body 200 can be detachably connected. When it is necessary to separate the rotating ring 220 and the second lamp body 200, the rotating ring 220 is rotated in the opposite direction so that the second snap-fit ​​portion 221 and the first snap-fit ​​portion 131a are misaligned, and then the rotating ring 220 is removed. The first snap-fit ​​part 131a and the second snap-fit ​​part 221 in this solution adopt the above structure, which not only facilitates the assembly and disassembly of the rotating ring 220 and the second lamp body 200, but also avoids breakage due to deformation.

[0057] Optionally, there are at least two first snap-fit ​​portions 131a, with each first snap-fit ​​portion 131a arranged at intervals along the circumference of the rotating ring 220. The second snap-fit ​​portions 221 are arranged in a one-to-one correspondence with the first snap-fit ​​portions 131a. This can further improve the connection stability and firmness between the rotating ring 220 and the first lamp tube 130.

[0058] In a further optional embodiment, the end face of the annular inner cylinder 131 is provided with a positioning groove 131b. The positioning groove 131b and the first snap-fit ​​portion 131a are arranged at intervals along the circumference of the first lamp tube 130. The rotating ring 220 is also provided with a positioning protrusion 222. The positioning protrusion 222 includes a support portion 222a and a protrusion 222b connected radially to the rotating ring 220. The support portion 222a is connected to the inner annular surface of the rotating ring 220. In this case, the connection area between the positioning protrusion 222 and the annular body of the rotating ring 220 is large, so that the structural strength at the connection between the two is greater. Of course, the positioning protrusion 222 can also be located on the end face of the rotating ring 220. The support portion 222a can undergo a certain deformation. In the circumferential direction of the rotating ring 220, the arc length of the protrusion 222b is less than the arc length of the support portion 222a. The support portion 222a rotates and engages with the outer circumferential surface of the annular inner cylinder 131 so that the protrusion 222b and the positioning groove 131b are positioned and engaged in the circumferential direction of the rotating ring 220.

[0059] During the assembly of the rotating ring 220, the positioning protrusion 222 and the second locking part 221 are both inserted between the annular inner cylinder 131 and the annular outer cylinder 132 of the first lamp tube 130. Then, the rotating ring 220 is rotated so that the second locking section 221b of the second locking part 221 is aligned with the first locking section 131a1 of the first locking part 131a. At the same time, the support part 222a rotates and engages with the outer circumferential surface of the annular inner cylinder 131. During this process, the positioning protrusion 222 undergoes slight deformation. When the rotating ring 220 rotates to the point where the protrusion 222b is aligned with the positioning groove 131b, the positioning protrusion 222... 2. The deformation is restored so that the protrusion 222b and the positioning groove 131b are positioned and engaged in the circumferential direction of the rotating ring 220, and the rotating ring 220 stops rotating. At this time, the limiting segment 131a2 of the second locking part 221 and the first locking part 131a can be positioned and engaged in the circumferential direction of the rotating ring 220, or they can be out of contact. When it is necessary to separate the rotating ring 220 from the second lamp body 200, the rotating ring 220 is rotated in the opposite direction so that the second locking part 221 and the first locking part 131a are misaligned, and at the same time the protrusion 222b and the positioning groove 131b are disengaged. Then the rotating ring 220 is removed. This solution uses the positioning protrusion 222 and the positioning groove 131b for positioning and engagement, which helps to further improve the engagement stability of the rotating ring 220 and the first lamp tube 130. Of course, the positioning protrusion 222 can also be omitted.

[0060] Optionally, guide slopes can be provided on both sides of the circumferential side of the positioning groove 131b and the protrusion 222b can be guided and cooperated with the guide slopes. This is beneficial to improving the assembly efficiency of the rotating ring 220 and the first lamp tube 130. At the same time, it can prevent the protrusion 222b from being damaged due to the large force it is subjected to.

[0061] Optionally, the number of positioning notches 223 can be at least two, with each positioning notch 223 arranged at intervals along the circumference of the rotating ring 220, and the positioning protrusions 241 corresponding to the positioning notches 223 one by one; the number of elastic locking parts 242 can be at least two, with each elastic locking part 242 arranged at intervals along the circumference of the rotating ring 220, and the locking grooves corresponding to the elastic locking parts 242 one by one, which can improve the connection stability and firmness between the rotating ring 220 and the face ring assembly 230.

[0062] Optionally, the first lamp body 100 and the second lamp body 200 can be connected by means of snap-fit ​​or other means; or, in another optional embodiment, the first lamp tube 130 further includes an annular connecting plate 133, the annular outer tube 132 is connected to the annular inner tube 131 through the annular connecting plate 133, the annular inner tube 131 is provided with a clearance notch 131c, the clearance notch 131c, the positioning groove 131b and the first snap-fit ​​part 131a are arranged at intervals along the circumference of the first lamp tube 130, the annular connecting plate 133 is provided with a through hole 133a, the through hole 133a and the clearance notch 131c are arranged along the radial direction of the first lamp tube 130, the lamp also includes a third fastener 300, one end of the third fastener 300 passes through the through hole 133a and is detachably connected to the photoelectric module 120 of the first lamp body 100, and the clearance notch 131c is used to avoid the third fastener 300. In this solution, the first lamp tube 130 of the first lamp body 100 and the photoelectric module 120 are connected by the third fastener 300, which helps to improve the connection stability and firmness between the two; in addition, the annular outer cylinder 132 can protect the annular inner cylinder 131 and other structures, and at the same time improve the aesthetics of the lamp.

[0063] Optionally, the rotating ring 220 and the face ring assembly 230 can be connected by screws or other connectors; or, in another optional embodiment, the end face of the rotating ring 220 facing away from the first lamp body 100 is provided with a positioning notch 223, and the second lamp body 200 also includes a fixing ring 240 and a second annular reflector 250. The fixing ring 240 and the second annular reflector 250 are both disposed in the receiving space of the face ring assembly 230. Optionally, the second annular reflector 250 and the face ring assembly 230 are fixedly connected by magnetic attraction. The inner ring surface of the fixed ring 240 is provided with a positioning protrusion 241. The positioning protrusion 241 and the positioning notch 223 are positioned and engaged in the circumferential direction of the rotating ring 220. The outer ring surface of the fixed ring 240 is provided with an elastic snap-fit ​​portion 242. The elastic snap-fit ​​portion 242 and the positioning protrusion 241 are arranged at intervals along the circumferential direction of the fixed ring 240. The inner ring surface of the face ring assembly 230 is provided with a snap-fit ​​groove. The fixed ring 240 is snap-fitted and engaged with the face ring assembly 230 through the elastic snap-fit ​​portion 242 and the snap-fit ​​groove. The second annular reflector 250 is located on the side of the fixed ring 240 away from the first lamp body 100. In this design, the rotating ring 220 and the surface ring assembly 230 are engaged by a fixing ring 240. This not only facilitates the assembly and disassembly of the rotating ring 220 and the surface ring assembly 230, but also avoids the need to open connection holes, thereby simplifying the manufacturing process of the rotating ring 220 and the surface ring assembly 230. In addition, the second annular reflector 250 is used to reflect the light emitted from the light-emitting surface, which helps to further improve the uniformity of the light.
