[0002] In lighting installations, the fixing devices for lamps can be configured as a fixed base and a connecting base. The fixed base can be placed on the mounting foundation, and the connecting base can connect to the lamp body. Both the fixed base and the connecting base are equipped with electrical and mechanical connection parts, thereby realizing the electrical and mechanical connection between the fixed base and the connecting base. Since the fixed base can be pre-installed on the mounting foundation, such as in each unit of a building, and the fixed base interface is of a standardized specification, different types of lamps can be directly installed indoors as long as they have an interface that matches the fixed base interface. This is quick and safe, and lamps can be easily replaced if they are damaged.

[0003] In some lighting fixtures, a power module also needs to be installed inside the connector. Typically, the power module and electrical connection parts are stacked on the side of the connector closer to the lamp body.

[0060] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] Please see Figure 1 and Figure 2 As shown, this invention discloses a lighting assembly 100, including a mounting base 10 for mounting to a mounting foundation (not shown) and a lighting fixture assembled and mated with the mounting base 10. The mounting base 10 is pre-installed on a base such as a roof or ceiling. The lighting fixture includes a chassis 20 adapted to the mounting base 10, a power supply box 50 located in the central region of the chassis 20, a light source module 30 fixed to the chassis 20 and electrically connected to the power supply box 50, and a faceplate 40 assembled and fixed with the chassis 20. The power supply box 50 is housed within the mask 40 and is configured to be electrically connected to and supply power to the light source module 30. It is also configured to be mechanically and electrically connected to the mounting base 10, which is mounted on the mounting base. The mounting base 10 is provided with an electrical connection part 11 that is connected to the mains power. The electrical connection between the electrical connection part 11 and the power supply box 50, and the electrical connection between the power supply box 50 and the light source module 30, can be used to supply power to the light source module 30 and turn on the lamp. An optical space is formed inside the mask 40, and the light source module 30 is housed in the optical space. The mask 40 is configured to emit the emitted light from the light source module 30.

[0062] The preferred light fixture of the present invention is a circular ceiling light. Correspondingly, the mounting base 10, chassis 20, light source module 30, mask 40, and power supply box 50 are also arranged in a circular or annular shape. Of course, the light fixture of the present invention can also be a square ceiling light or a ceiling light of other shapes. In this case, only the shape and specific structure of the mounting base 10, chassis 20, light source module 30, mask 40, and power supply box 50 need to be adjusted accordingly. For ease of description, the following description will use a circular ceiling light as an example, but it should not be considered a limitation.

[0063] like Figure 5 and Figure 9 As shown, the mounting base 10 includes a receiving portion 101 having a cylindrical cavity and a positioning portion 102 arranged around the outer wall of the receiving portion 101. The positioning portion 102 is connected to the outer wall surface of the receiving portion 101 and is located at the middle position of the outer wall surface of the receiving portion 101. A clearance hole 103 is provided on the receiving portion 101, and the electrical connection portion 11 is received in the cavity of the receiving portion 101 and connected to the mains power through the clearance hole 103. The electrical connection part 11 is a junction box, including a cylindrical first docking part 111 of a certain height distributed from the outside to the inside, a cylindrical second docking part 112 disposed within the first docking part 111 and parallel to and at the same height as the first docking part 111, and a cylindrical third docking part 113 disposed within the second docking part 112 and parallel to and at the same height as the second docking part 112. An annular first receiving groove 114 is formed between the first docking part 111 and the second docking part 112, and an annular second receiving groove 115 is formed between the second docking part 112 and the third docking part 113. A circular third receiving groove 116 is provided in the center of the third docking part 113. Further, the first receiving groove 114 is used to receive the L electrode (not shown), the second receiving groove 115 is used to receive the N electrode (not shown), and the third receiving groove 116 is used to receive the grounding electrode (not shown), thereby realizing the connection between the junction box 11 and the mains power. Of course, the grounding electrode can also be omitted, and only the L electrode and the N electrode are provided to enable the junction box 11 to be energized.

[0064] like Figure 3 As shown, the central area of ​​the chassis 20 is provided with a mounting hole 21 and a mounting part 22. The mounting hole 21 penetrates the chassis 20, making the chassis 20 as a whole circular. The power supply box 50 is assembled and fixed in the mounting hole 21, and the light source module 30 is fixed on the chassis 20 and surrounds the power supply box 50. This not only ensures that the power supply box 50 and the light source module 30 can be electrically connected, but also the layout of the power supply box 50 and the light source module 30 is compact and reasonable, without increasing the thickness of the circular ceiling light, thus meeting the requirements of thinness and lightness.

[0065] The light source module 30 includes a light source plate 31 and LED beads 32 fixed on the light source plate 31. The LED beads 32 are evenly distributed on the light source plate 31 to ensure uniform light output. In this embodiment, three light source modules 30 are provided and combined to form a circular whole, which is fixedly connected to the chassis 20. Of course, in other embodiments, the light source module 30 can also be directly arranged in a circular shape without being divided into multiple parts, as long as uniform light output can be achieved.

[0066] Combination Figures 4 to 11As shown, the power supply box 50 includes a base 51, a power supply cover 53, a drive module 521 and a control module integrated in the base 51 and electrically connected to the light source module 30, an electrical connection part 522 electrically connected to the drive module 521, and a mechanical connection part located on the outer periphery of the electrical connection part 522. The mechanical connection part and the electrical connection part 522 are configured to mechanically and electrically connect with the mechanical mating part and the electrical connection part 11 provided on the mounting base 10 to supply power to the light source module 30 and drive the light source module 30.

[0067] Specifically, the power cover 53 is assembled and fixed to the base 51, forming a receiving space between the base 51 and the power cover 53, in which the drive module 521 and the control module are both housed. A mechanical connection is located on the side of the base 51 opposite to the drive module 521, and is configured to be fixedly connected to the fixing seat 10 by a rotating snap-fit ​​or a direct push. Specifically, the mechanical connection includes a first engaging portion 514 located on the inner side of the bottom end face of the base 51, which is snapped and fixed to a second engaging portion 104 within the fixing seat 10 by axial rotation. The base 51 includes a main body 501 and an annular fixing portion 502 protruding from the main body 501 toward the fixing seat 10. The first engaging portion 514 is located on the inner side of the annular fixing portion 502 and has a first gap 503 between it and the main body 501. The first connecting part 514 is a first positioning block that extends from the bottom of the inner side wall of the annular fixing part 502. The second connecting part 104 is a second positioning block located inside the receiving part 101. A second gap 105 is left between the lower surface of the second positioning block and the bottom surface of the fixing seat 10. Thus, when assembling the base 51 onto the fixing seat 10, the base 51 can be pushed into the cylindrical cavity of the receiving part 101 first, and then the base 51 can be rotated so that the first connecting part 514 enters the second gap 105 and the second connecting part 104 enters the first gap 503. After releasing the base 51, the first connecting part 514 and the second connecting part 104 abut against each other and are positioned. At this time, the assembly and fixing of the base 51 and the fixing seat 10 are realized.

[0068] Preferably, the bottom of the fixed base 10 is also provided with a positioning groove 12 that corresponds to and communicates with the second gap 105, so that when assembling the base 51 and the fixed base 10, the positioning groove 12 can provide assembly space for the first joint 514, provide the possibility for the elastic deformation of the first joint 514, and ensure that the base 51 and the fixed base 10 can be smoothly assembled.

[0069] Furthermore, the mechanical connection also includes a third connecting part 513 located on the main body 501 and outside the annular fixing part 502, which abuts against and fixes against the fourth connecting part 106 inside the fixing seat 10. Specifically, the third connecting part 513 is a limiting block located on the lower surface of the overlapping part 511 of the main body 501, and the fourth connecting part 106 is a deformable structure located on the positioning part 102. Thus, after the base 51 and the fixing seat 10 are assembled, the mutual abutment of the third connecting part 513 and the fourth connecting part 106 can be used to restrict the base 51 from sliding freely relative to the fixing seat 10, thereby improving the connection stability between the base 51 and the fixing seat 10.

[0070] In summary, the mechanical connection parts on the power supply box 50 mainly include the first joint 514 and the third joint 513, and the mechanical mating parts on the fixed base 10 mainly include the second joint 104 and the fourth joint 106. Thus, the mechanical connection between the power supply box 50 and the fixed base 10 can be achieved by the mutual cooperation between the mechanical connection parts of the power supply box 50 and the mechanical mating parts of the fixed base 10.

[0071] The electrical connection part 522 is located in the central area of ​​the base 51 and includes an insulating part 523 connected to the base 51 and a first conductive terminal 524, a second conductive terminal 525 and a third conductive terminal 526 fixed to the insulating part 523 and distributed sequentially from the outside to the inside. The first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526 each include an electrically conductive portion 5201 and an electrically connected portion 5202 disposed opposite to the electrically conductive portion 5201. The electrically conductive portions 5201 of the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526 all extend beyond the insulating portion 523 in the height direction and are electrically connected to the drive module 521. The electrically connected portions 5202 of the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526 also extend beyond the insulating portion 523 and are electrically connected to the fixing base 10. The third conductive terminal 526 is fixed at the center position of the insulating portion 523, and the first conductive terminal 524 and the second conductive terminal 525 surround the outer periphery of the third conductive terminal 526. When the base 51 is assembled into the fixing seat 10, the electrical connection portions 5202 of the first conductive terminal 524, the second conductive terminal 525 and the third conductive terminal 526 are respectively accommodated in the first receiving groove 114, the second receiving groove 115 and the third receiving groove 116 and electrically connected to the electrodes in the corresponding receiving grooves, thereby realizing the electrical connection between the electrical connection portion 522 of the power supply box 50 and the electrical connection portion 11 of the fixing seat 10.

[0072] Furthermore, the electrical connection portion 5202 of the first conductive terminal 524 and the second conductive terminal 525 is a metal ring adapted to the size and shape of the first receiving groove 114 and the second receiving groove 115, respectively, and the electrical connection portion 5202 of the third conductive terminal 526 is a metal pin adapted to the size and shape of the third receiving groove 116. This ring-shaped electrical connection increases the contact area between the first receiving groove 114, the second receiving groove 115, and the third receiving groove 116 and the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526, enabling the electrical connection portion 522 and the electrical connection portion 11 to achieve electrical connection in any relative rotational positioning direction. Simultaneously, because the first mating portion 111, the second mating portion 112, and the third mating portion 113 completely insulate the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526, electrical safety is improved.

[0073] In this application, the electrical connection portions 5202 of the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526 all extend beyond the insulating portion 523 to make electrical contact with the first mating portion 111, the second mating portion 112, and the third mating portion 113 within the fixing base 10. Of course, the electrical connection portions 5202 of the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526 can also be disposed inside the insulating portion 523. In this case, the first mating portion 111, the second mating portion 112, and the third mating portion 113 within the fixing base 10 are respectively configured as protruding structures, which can also achieve electrical contact between the electrical connection portions 5202 and the corresponding mating portions.

[0074] Furthermore, the electrical connection portion 522 of this application is located in the central region of the base 51, and the mechanical connection portion is located on the outer periphery of the electrical connection portion 522, thereby realizing the electrical and mechanical connection between the power supply box 50 and the fixed seat 10. To ensure the connection stability between the power supply box 50 and the fixed seat 10, an elastic abutment element 57 can be provided on the side of the base 51 facing the fixed seat 10, so that the base 51 and the fixed seat 10 press against each other, thereby increasing the stability of the connection between the base 51 and the fixed seat 10 and preventing the base 51 from loosening from the fixed seat 10. Of course, the elastic abutment element 57 can also be provided on the fixed seat 10, or elastic abutment elements 57 can be provided on both the base 51 and the fixed seat 10 to further increase the stability between the base 51 and the fixed seat 10. The elastic abutment element 57 can be a rubber column or an elastic gasket, etc., and can be assembled to the fixed seat 10 and the base 51 and provided with a spring to increase elasticity; there is no limitation here.

[0075] The base 51 has a receiving cavity 515 for accommodating the drive module 521 and a receiving hole 516 for accommodating the electrical connection part 522. The receiving hole 516 is located in the central area of ​​the base 51, and the receiving cavity 515 is arranged around the receiving hole 516. Correspondingly, the drive module 521 has an opening at its center and is arranged around the outside of the electrical connection part 522. This arrangement reduces the height difference between the drive module 521 and the electrical connection part 522, meeting the requirement of a thinner and lighter lamp. In this application, the drive module 521 is a power board, which also integrates a control module to control the lighting, extinguishing, brightness adjustment, color temperature adjustment, and other functions of the light source module 30.

[0076] In this application, the power supply box 50 is assembled and fixed with the chassis 20, and the chassis 20 is specifically configured to use an external locking member passing through the outer edges of the mounting part 22 and the base 51 to lock and fix the chassis 20 and the base 51. Of course, in other embodiments, the chassis 20 can also be configured to be snapped and fixed with the base 51. Specifically, in this embodiment, the base 51 is configured to pass through the mounting hole 21 and connect to the mounting part 22, and the electrical connection part 522 is fixed in the base 51 and electrically connected to the electrical connection part 11 in the light source module 30 and the fixing seat 10 respectively to supply power to the light source module 30. Preferably, the mounting hole 21 is located inside the mounting part 22, and the base 51 is provided with an overlapping part 511 that overlaps and cooperates with the mounting part 22. During assembly, the overlapping part 511 of the base 51 overlaps the mounting part 22 and is limited and connected to the mounting part 22.

[0077] The chassis 20 is also provided with a through hole 23 and a limiting hole 24. The through hole 23 passes through the mounting part 22, and the limiting hole 24 is formed on the mounting part 22 and communicates with the mounting hole 21. The base 51 is provided with a receiving hole 512 and a third connecting part 513. The third connecting part 513 is received in the limiting hole 24, and the receiving hole 512 corresponds to the through hole 23. Thus, an external locking member can pass through the through hole 23 and be received in the receiving hole 512 to lock and fix the chassis 20 and the base 51. Of course, the through hole 23 and the limiting hole 24 can also be provided on the base 51. In this case, the receiving hole 512 and the third connecting part 513 are respectively provided on the chassis 20, which can also achieve the locking and fixing of the chassis 20 and the base 51. Preferably, in this embodiment, the receiving hole 512 is recessed inward from the side of the overlapping portion 511 near the fixing seat 10, and the third connecting portion 513 protrudes from the side of the overlapping portion 511 near the fixing seat 10. The external locking element is a screw. It is understood that in other embodiments, the chassis 20 and the base 51 can also be fixed by other means, such as: snap-fit ​​fixing, interference fit, welding fixing, adhesive fixing, etc., or the chassis 20 can also be directly integrally set with the base 51. Examples will not be given here.

[0078] A support member 510 is formed within the receiving cavity 515. The support member 510 is stepped and is used to support the drive module 521 and limit its movement. The electrical connection part 522 is locked and fixed to the base 51, and the drive module 521 is also locked and fixed to the base 51. The drive module 521 surrounds the electrical connection part 522 and is electrically connected to it. Thus, when the electrical connection part 522 is electrically connected to the electrical connection part 11, power can be transmitted to the drive module 521, thereby powering the lamp bead 32 and illuminating it.

[0079] A fixing part 517 is provided on the side of the receiving hole 516. The fixing part 517 has a fixing hole 518. A locking part 527 is formed on the insulating part 523 of the electrical connection part 522. The locking part 527 has a locking hole 528. Therefore, when the electrical connection part 522 is received in the receiving hole 516, an external locking member can pass through the locking hole 528 and the fixing hole 518 to lock the insulating part 523 of the electrical connection part 522 to the base 51. Alternatively, the insulating part 523 of the electrical connection part 522 can be integrally formed with the base 51. In this case, the electrical connection part 522 is also located at the center of the base 51, and the drive module 521 surrounds the outside of the electrical connection part 522, thus achieving electrical connection between the drive module 521 and the electrical connection part 522. Specifically, as shown... Figure 13 As shown.

[0080] Combination Figure 29 and Figure 30 As shown, the driver module 521 also integrates an NFC module (unlabeled). This NFC module can edit the product information and control methods of the lamp according to the NFC editing program. For example, the lamp in this application is a ceiling light that uses a digital power supply. Users can read and write product information and edit the lamp control methods, such as adjusting the lamp's color temperature ratio, brightness, and soft-light effect, on a terminal device (such as a mobile phone 70) according to the NFC editing program. In specific operation, users can open the cover 40 to refresh the NFC program, or they can refresh the NFC program directly outside the lamp.

[0081] like Figure 12 and Figure 13 As shown, a power cord 525 is also connected to the drive module 521. One end of the power cord 525 is soldered to the drive module 521, and the other end is soldered to the electrical conduction part 5201 of the first conductive terminal 524, the second conductive terminal 525, and the third conductive terminal 526. In this way, the drive module 521 and the electrical connection part 522 can be electrically connected by the power cord 525.

[0082] like Figure 14 and Figure 15As shown, the power supply box 50 is also connected to a smart component 54, which is electrically connected to the drive module 521 to drive the light source module 30 to turn on / off / adjust brightness / color temperature, etc. Specifically, the smart component 54 is provided with a docking interface (not shown), and the outer wall of the power supply cover 53 is recessed with a receiving groove 531 for accommodating the smart component 54. A plug-in interface 532 is provided within the receiving groove 531. When the smart component 54 is accommodated within the receiving groove 531, the docking interface of the smart component 54 and the plug-in interface 532 are plugged into each other to achieve an electrical connection between the smart component 54 and the power supply box 50. In this embodiment, the smart component 54 is locked and fixed within the receiving groove 531 by a locking member 60.

[0083] like Figure 16 As shown, in other embodiments, the smart component 54 can also be fixed on the side of the base 51 near the fixing seat 10. In this case, the receiving slot is opened on the side of the base 51 near the fixing seat 10. The receiving slot is also provided with a plug-in interface so that when the smart component 54 is received in the receiving slot, the interface of the smart component 54 can be plugged into the plug-in interface to achieve electrical connection.

[0084] Or, such as Figure 17 and Figure 18 As shown, the receiving slot can also be placed on the chassis 20. In this case, the power supply box 50 is provided with a lead wire 55 connected to the drive module 521 and led out to the outside of the power supply box 50. The end of the lead wire 55 is connected to a plug interface 532. In use, the plug interface 532 is directly inserted into the interface 541 of the smart component 54 to realize the electrical connection between the smart component 54 and the drive module 521. Furthermore, the receiving slot is located on the outside of the light source module 30. Since there are three light source modules 30 in this application, the lead wire 55 can pass through the gap between two of the light source modules 30. This not only results in a compact arrangement and high space utilization, but also does not obstruct the light source module 30 and does not affect the light output effect.

[0085] In summary, the installation position of the intelligent component 54 is not fixed and can be adjusted according to the actual situation, as long as it can achieve electrical connection with the drive module 521. There are no restrictions here.

[0086] In this application, the chassis 20 is made of metal, and the base 51 is made of plastic. To increase the structural strength of the power box 50, at least two circumferentially fixed reinforcing members 56 can be provided inside the base 51. These reinforcing members 56 are housed in the receiving cavity 515 and extend to connect with the first joint 514, thereby increasing the connection strength between the base 51 and the fixing seat 10. Since there are many types of reinforcing members 56, in order to clearly describe their main functions, the following will use two of their structures as examples to describe the specific structure and main function of the reinforcing members 56 in detail, but this should not be considered a limitation.

[0087] Example 1, such as Figures 19 to 22 As shown, the reinforcing member 56 includes a base 563 fixed in the base 51, a fixing part 561 connected to the first connecting part 514, and a connecting part 562 connecting the fixing part 561 and the base 563. The fixing part 561 and the base 563 extend in two mutually parallel planes, and the connecting part 562 is perpendicular to both the fixing part 561 and the base 563.

[0088] In this embodiment, the fixing part 561 and the base part 563 extend in the same direction at both ends of the connecting part 562, so that the reinforcing member 56 is C-shaped as a whole. The fixing part 561 is bent to better cooperate with the first connecting part 514, thereby strengthening the load-bearing capacity of the first connecting part 514. The base part 563 is rectangular, and there are two connecting parts 562 that extend vertically downward from the same side (specifically the long side) of the base part 563. There are also two corresponding fixing parts 561 to connect to the two connecting parts 562 respectively. Of course, there can be only one or more connecting parts 562 and fixing parts 561, as long as the reinforcing effect can be achieved.

[0089] Furthermore, the reinforcing member 56 also includes support portions 564 extending outward from the two short sides of the base 563. The base 51 has a mounting space 519, within which the base 563 is housed. Both support portions 564 overlap the outer side of the mounting space 519. Preferably, the base 563 extends horizontally, and the two support portions 564 protrude upward from the two short sides of the base 563 and then extend horizontally, so that when the base 563 is housed in the mounting space 519, the two support portions 564 can overlap the outer edge of the mounting space 519, providing positioning for the reinforcing member 56 and strengthening the load-bearing capacity of the first joint 514. The power cover 53 has support ribs 533 protruding towards the base 563, so that when the power cover 53 is assembled and fixed to the base 51, the support ribs 533 can be used to abut against the base 563 to prevent the reinforcing member 56 from falling out of the mounting space 519.

[0090] The base 51 also has an opening 504 for the fixing part 561 to pass through and a mounting part 505 located outside the mounting space 519. Since there are two fixing parts 561 in this embodiment, there are also two openings 504, both of which are connected to the mounting space 519. There are also two mounting parts 505 for fixing the two support parts 564. During assembly, the two fixing parts 561 pass through the corresponding openings 504 and are connected to the first connecting part 514. The base 563 is housed in the mounting space 519, and the two support parts 564 are respectively overlapped and fixed on the corresponding mounting parts 505. At this time, the assembly of the reinforcing member 56 is completed.

[0091] like Figure 23 and Figure 24 As shown in this application, the fixing part 561 is fitted into the first connecting part 514 to increase the structural strength of the first connecting part 514. Thus, when the first connecting part 514 and the second connecting part 104 are mechanically connected, the first connecting part 514 can be stably hung on the second connecting part 104 and will not break due to insufficient structural strength, causing the lamp to fall.

[0092] Understandable, such as Figure 5 As shown, a reinforcing structure 107 is also provided in the fixed base 10 at the position corresponding to the second joint 104. The reinforcing structure 107 is arranged in a Z shape and is mainly used to increase the structural strength of the second joint 104 to ensure the structural stability when the first joint 514 and the second joint 104 are mechanically connected.

[0093] Example 2, as follows Figures 25 to 28 As shown, the structure of the reinforcing member 56' in this embodiment is largely the same as that in embodiment 1. The main difference is that in this embodiment, the fixing part 561' and the base part 563' extend in opposite directions at both ends of the connecting part 562', so that the reinforcing member 56' is Z-shaped. The fixing part 561' is connected to the first connecting part 514 to mechanically connect with the second connecting part 104. At this time, the reinforcing member 56' can also strengthen the load-bearing capacity of the first connecting part 514. In addition, the base part 563' is provided with a first fixing hole 565, and correspondingly, the power cover 53' is provided with a second fixing hole (unlabeled). The base 51' is provided with a protrusion 506, so that the protrusion 506 can pass through the first fixing hole 565 and the second fixing hole respectively to fix and connect the power cover 53' and the base 51'.

[0094] In summary, this invention integrates a drive module 521 electrically connected to the light source module 30, an electrical connection part 522 electrically connected to the drive module 521, and a mechanical connection part located on the periphery of the electrical connection part 522 within the power supply box 50. This allows for mechanical and electrical connection with the mounting base 10 on the mounting foundation, thereby supplying power to and driving the light source module 30. Furthermore, the power supply box 50 is assembled and fixed to the chassis 20, and the height difference between the assembled power supply box 50 and the mounting base 10 is small, meeting the requirements for a thin and light design. Additionally, the modular design of the power supply box 50 facilitates maintenance and replacement, and allows for complete replacement.

[0095] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
