[0051] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] Please also read Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig.10 Now, the downlight provided by the utility model is described. The downlight comprises a lamp body 1 and a driving assembly 2. A light source module 11 is provided inside the lamp body 1, and an electrical connection structure 12 is provided on the light source module 11; the driving assembly 2 is arranged on the backlight surface of the lamp body 1; a driving module 21 is provided inside the driving assembly 2, and an electric contact structure 22 is provided on the driving module 21; wherein the electric connection structure 12 passes through the lamp body 1 and the driving assembly 2 in sequence, and is plugged and matched with the electric contact structure 22 and electrically connected.

[0053] The driving assembly 2 and the lamp body 1 may be detachably connected to facilitate replacement of the driving assembly 2 or replacement of the light source module 11 inside the lamp body 1. Specifically, the driving assembly 2 may be connected to the lamp body 1 by at least one of a snap-on structure, a plug-in structure, and a screw-on structure, or the driving assembly 2 may be placed on the backlight surface of the lamp body 1 and supported by the lamp body 1, and the two are connected only by plugging the electrical connection structure 12 and the electric contact structure 22. Of course, the driving assembly 2 and the lamp body 1 may also be fixedly connected.

[0054] The electrical connection structure 12 and the electric contact structure 22 are both charged bodies, and the two are plugged in and conduct when powered, thereby achieving conduction between the driving module 21 and the light source module 11. The electrical connection structure 12 is directly fixed on the light source module 11, and no connecting wires are required. The electric contact structure 22 is directly fixed on the driving module 21, and no connecting wires are required.

[0055] Before the downlight provided in this embodiment is installed on the ceiling, the driving assembly 2 can be connected to the lamp body 1 first, and then the whole can be assembled on the ceiling. Alternatively, the lamp body 1 can be assembled on the ceiling first, and then the driving assembly 2 can be installed on the backlight surface of the lamp body 1.

[0056] Compared with the prior art, the downlight provided by the utility model has a driving component 2 directly arranged on the backlight surface of the lamp body 1, and the driving component 2 is fixed by means of the lamp body 1, thereby reducing the space occupied by the downlight; an electrical connection structure 12 is provided on the light source module 11 of the lamp body 1, and an electric contact structure 22 is provided on the driving module 21 of the driving component 2, and the electrical connection structure 12 and the electric contact structure 22 are plugged together and electrically connected, so that the driving module 21 and the light source module 11 can be connected without using wires, and there is no need to pre-bury wires, and the plug-in operation is simple and quick, which simplifies the installation operation of the downlight and eliminates safety hazards.

[0057] In some embodiments, the electrical connection structure 12 and the contact structure 22 may be formed by Figure 2 , Figure 7 and Fig.10 The structure shown, see Figure 2 , Figure 7 and Fig.10 The electrical connection structure 12 is a telescopic terminal, and the electric contact structure 22 is an electric contact hole; specifically, a first clearance hole 131 is provided on the lamp body 1, and a second clearance hole 231 is provided on the driving assembly 2. The first clearance hole 131, the second clearance hole 231 and the electric contact hole correspond axially.

[0058] The telescopic terminal is welded and fixed on the light source module 11, and the telescopic terminal passes through the electric contact hole and contacts the wall of the electric contact hole, thereby realizing a conductive connection. Specifically, according to the needs of the conductive connection, two groups of telescopic terminals are welded on the light source module 11, and the number of each group of telescopic terminals is three. Correspondingly, two groups of electric contact holes are opened on the driving module 21, and the number of each group of electric contact holes is three. The aperture of the electric contact hole is adapted to the outer diameter of the telescopic terminal. Of course, in order to adapt to electric contact holes of different sizes, the insertion end of the telescopic terminal can be designed as a conical structure.

[0059] Conductive connection is achieved by plugging the telescopic terminal into the contact hole, which simplifies the structure of the light source module 11 and the driving module 21 and saves the cost of the downlight.

[0060] In addition, the aperture of the first clearance hole 131 and the aperture of the second clearance hole 231 are adapted to the external dimensions of each group of telescopic terminals. For example, if there are three telescopic terminals in each group, and the three telescopic terminals are arranged side by side, then the first clearance hole 131 can be designed as a bar hole or a waist hole, and the length of the first clearance hole 131 can be adapted to the length of a group of telescopic terminals, and the width of the first clearance hole 131 can be adapted to the outer diameter of a telescopic terminal. The same size format is applicable to the second clearance hole 231.

[0061] Since the sizes of the first clearance hole 131 and the second clearance hole 231 are adapted to the telescopic terminal, the apertures of the first clearance hole 131 and the second clearance hole 231 can be reduced accordingly to meet the fire protection requirements of the entire lamp.

[0062] In addition, in order to limit the extension direction of the telescopic terminal, a limit platform can be set above the first clearance hole 131 and / or the second clearance hole 231, and the limit platform has through holes with the same number as a group of telescopic terminals, and the aperture of the through holes is adapted to the outer diameter of the telescopic terminal.

[0063] In some embodiments, the telescopic terminal can be used as follows Figure 3 The structure shown, see Figure 3The telescopic terminal includes a fixing seat 121, an elastic body 122 and an ejector pin 123. The fixing seat 121 is fixedly arranged on the light source module 11; the fixing seat 121 has a receiving cavity; the elastic body 122 is arranged in the receiving cavity, and one end thereof abuts against the cavity wall of the receiving cavity; one end of the ejector pin 123 is limited in the receiving cavity and abuts against the other end of the elastic body 122, and the other end is inserted into the contact hole.

[0064] The accommodating cavity has a cavity opening facing the electric contact hole, the elastic body 122 is completely placed in the accommodating cavity, one end of the ejector pin 123 is placed in the accommodating cavity from the cavity opening, and the other end extends out of the accommodating cavity. The elastic body 122 has elastic freedom along the axial direction of the electric contact hole.

[0065] The elastic body 122 can provide pre-tightening force to the ejector pin 123 to ensure that the insertion end of the ejector pin 123 is inserted into and passes through the electric contact hole, and enables the light source module 11 to adapt to different driving modules 21, reducing the influence of the tolerance of the plug-in fit between the telescopic terminal and the electric contact hole.

[0066] In some embodiments, the lamp body 1 and the driving assembly 2 may be connected by Figure 1 , Figure 4 and Figure 5 The structure shown, see Figure 1 , Figure 4 and Figure 5 A connecting ear 15 is provided on the backlight surface of the lamp body 1, and the connecting ear 15 is located on the periphery of the driving component 2. A card interface 151 is also opened on the connecting ear 15; a card block 241 is provided on the outer wall of the driving component 2, and the card block 241 is limited to be located in the card interface 151.

[0067] The connection ear 15 is extended upward relative to the lamp body 1 to surround the periphery of the driving assembly 2. In addition to being detachably connected to the driving assembly 2, the connection ear 15 is also used to set a spring arm. The downlight is fixed on the ceiling by the spring arm.

[0068] Specifically, two groups of connecting ears 15 are provided and are symmetrically distributed, and each group of connecting ears 15 is provided with a spring arm and a card interface 151. Two groups of card blocks 241 are correspondingly provided on the outer wall of the driving component 2.

[0069] The block 241 has the freedom to move radially inwards of the downlight, so the interior of the driving assembly 2 has an escape space for avoiding the block 241 to move slightly inwards. Specifically, when the block 241 is inserted into the card interface 151, the driving assembly 2 is fixed to the lamp body 1. When the block 241 is manually pinched radially inwards, the block 241 can be separated from the card interface 151, and then the driving assembly 2 can be manually pulled outwards along the axial direction to separate the driving assembly 2 from the lamp body 1.

[0070] The two sets of connecting ears 15 not only play the role of fixing the spring arm to fix the downlight, but also play the role of limiting the driving assembly 2 to ensure that the driving assembly 2 and the lamp body 1 are stably fixed after the downlight is assembled. In addition, the connecting ears 15 and the driving assembly 2 are easy to assemble and disassemble, so that the driving assembly 2 is easy to replace.

[0071] In some embodiments, the drive assembly 2 may be configured as follows: Fig.10 The structure shown, see Fig.10 The driving assembly 2 includes a base 23 , the driving module 21 and a cover 24 . The driving module 21 is disposed on the base 23 ; the cover 24 is buckled on the base 23 and covers the periphery of the driving module 21 .

[0072] The base 23 is used to fix and support the driving module 21, and to achieve insulation isolation from the outer surface of the lamp body 1. The cover 24 is used to shield the driving module 21. The cover 24 and the base 23 form a closed space, and the driving module 21 is confined in the above-mentioned closed space.

[0073] Specifically, two groups of blocks 241 are arranged on the outer peripheral wall of the cover body 24. The second clearance hole 231 is arranged on the base 23.

[0074] In order to achieve a stable connection between the base 23 and the driving module 21, on the basis of the above embodiment, a positioning column 232 is provided on the base 23, and a positioning hole 211 is provided on the driving module 21, and the positioning column 232 is plugged into the positioning hole 211; the base 23 is also provided with a second hook 233, and the second hook 233 is abutted against the driving module 21 up and down to limit the position.

[0075] The positioning column 232 is plugged into the positioning hole 211 to limit the circumferential position of the base 23 and the driving module 21. The hook surface of the second hook 233 abuts against the plate surface of the driving module 21 up and down to limit the driving module 21 up and down, thereby ensuring that the driving module 21 and the base 23 are stably assembled.

[0076] In some embodiments, the lamp body 1 may be Figure 7 The structure shown, see Figure 7 The lamp body 1 includes a shading surface ring 13, the above-mentioned light source module 11 and a decorative surface ring 14. The light emitting surface of the shading surface ring 13 is an open surface; the driving assembly 2 is arranged on the backlight surface of the shading surface ring 13; the light source module 11 is arranged inside the shading surface ring 13; the decorative surface ring 14 is arranged on the bottom surface of the shading surface ring 13 and is detachably connected to the shading surface ring 13.

[0077] Specifically, the shading surface ring 13 includes a cylindrical portion with an inner cavity and an open bottom surface, and a circular plate integrally formed on the outer periphery of the bottom surface of the cylindrical portion. The cylindrical portion is mainly used to install the light source module 11, and the circular plate is mainly used to be detachably connected to the decorative surface ring 14. Two sets of connecting ears 15 are provided on the backlight surface of the shading surface ring 13.

[0078] Due to the limitation of the structure of the shading surface ring 13 itself and the requirement of assembly with the light source module 11, the bottom surface of the circular plate is not a complete plane, but has a groove structure. In order to shield the circular plate, a decorative surface ring 14 is also installed on the bottom surface of the circular plate, so that the downlight has a good appearance.

[0079] The decorative surface ring 14 is detachably connected to the light shielding surface ring 13. After the decorative surface ring 14 is removed, the light source module 11 can be replaced. Replacing the light source module 11 alone can reduce maintenance costs. Specifically, the decorative surface ring 14 and the light shielding surface ring 13 can be detachably connected by at least one of a snap-on structure, a screw-on structure, and a plug-in structure.

[0080] In order to facilitate manual disassembly of the decorative surface ring 14 and the light source module 11, please refer to Figure 2 , Figure 7 and Figure 8 On the basis of the above-mentioned embodiment, a plurality of groups of strip ridges 132 are evenly spaced on the outer peripheral wall of the shading surface ring 13; a recessed groove 114 is provided on the outer peripheral wall of the light source module 11, and a limit block 115 is provided in the recessed groove 114, and a clearance is provided between the limit block 115 and one side wall of the recessed groove 114; a convex block 141 corresponding to the plurality of groups of strip ridges 132 is provided on the inner peripheral wall of the decorative surface ring 14, and the circumferential length of the convex block 141 is less than the circumferential length of the strip ridge 132; a first hook 142 is also provided on the top surface of the decorative surface ring 14.

[0081] Among them, the decorative surface ring 14 has a fixed position, a first disassembly position and a second disassembly position; when in the fixed position, the protrusion 141 is in vertical contact with the corresponding strip rib 132; when in the first disassembly position, the protrusion 141 is circumferentially misaligned with the corresponding strip rib 132, and the first hook 142 is in vertical contact with the limit block 115; when in the second disassembly position, the protrusion 141 is circumferentially misaligned with the corresponding strip rib 132, and the first hook 142 is located within the clearance spacing.

[0082] Specifically, the strip convex ridges 132 are arranged on the outer circumferential surface of the circular plate of the light shielding surface ring 13 and are evenly spaced along the circumferential direction. The convex blocks 141 are arranged on the inner circumferential surface of the decorative surface ring 14, the first hooks 142 are arranged on the top surface of the decorative surface ring 14, and at least two groups of the first hooks 142 are evenly spaced along the circumferential direction of the decorative surface ring 14, and the sinks 114 and the limit blocks 115 correspond to the first hooks 142 one by one.

[0083] The decorative surface ring 14 can be switched between a fixed position, a first disassembly position, and a second disassembly position by rotating. When the protrusion 141 is rotated to abut against the strip convex rib 132 (i.e., the lower surface of the protrusion 141 abuts against the upper surface of the strip convex rib 132), the protrusion 141 and the strip convex rib 132 are limited in position, and the decorative surface ring 14 is in a fixed position and cannot be separated from the light-shielding surface ring 13.

[0084] When the protrusion 141 is rotated to disengage from the corresponding strip ridge 132, and the first hook 142 is abutted against the limit block 115 up and down (the hook surface of the first hook 142 is abutted against the upper surface of the limit block 115), the decorative surface ring 14 is in the first disassembly position, and the decorative surface ring 14 and the shading surface ring 13 are no longer limited, but the upper and lower limits between the decorative surface ring 14 and the light source module 11 are integrated. By pulling the decorative surface ring 14, the light source module 11 can be separated from the shading surface ring 13, thereby realizing the disassembly of the light source module 11.

[0085] It should be noted that, since the electrical connection structure 12 and the electric contact structure 22 are plugged together, manually pulling the decorative surface ring 14 can overcome the plugging force of the electrical connection structure 12 and the electric contact structure 22 to separate the two.

[0086] When the protrusion 141 is rotated to disengage from the corresponding strip ridge 132 and the first hook 142 is located within the clearance interval, the decorative surface ring 14 is in the second disassembly position, and there is no limit between the decorative surface ring 14 and the shading surface ring 13, and there is no limit between the decorative surface ring 14 and the light source module 11. The decorative surface ring 14 can be removed separately by pulling the decorative surface ring 14.

[0087] By making the decorative surface ring 14 and the shading surface ring 13 detachably connected, and adding a connection between the decorative surface ring 14 and the light source module 11, the decorative surface ring 14 has the dual effects of being disassembled separately and together with the light source module 11, so as to facilitate the maintenance or replacement of the light source module 11 and meet the different disassembly and assembly needs of users.

[0088] In one embodiment, in the rotation axis direction, the first disassembly position, the second disassembly position, and the fixed position are distributed in sequence. In order to facilitate the calibration of different positions of the decorative surface ring 14, three protrusions can be set in the groove 114, wherein the first protrusion is located above the limit block 115 (the protrusion corresponds to the first disassembly position), the second protrusion is located within the clearance interval and close to the side wall of the limit block 115 (the protrusion corresponds to the second disassembly position), and the third protrusion is located within the clearance interval and close to the side wall of the groove 114 (the protrusion corresponds to the fixed position). Of course, only the first protrusion and the second protrusion can be set, and the third protrusion can be omitted.

[0089] In another embodiment, the fixed position is located between the first disassembly position and the second disassembly position in the rotation circumferential direction. When switching from the fixed position to the first disassembly position, the decorative surface ring 14 can be rotated counterclockwise, and when switching from the fixed position to the second disassembly position, the decorative surface ring 14 can be rotated clockwise. By limiting the difference in rotation direction, the first disassembly position and the second disassembly position are clearly indicated to the user.

[0090] In some embodiments, the light source assembly 11 may be configured as follows: Figure 2 , Figure 5 , Figure 6 and Figure 8 The structure shown, see Figure 2 , Figure 5 , Figure 6 and Figure 8 The light source module 11 includes a housing 111, a light source board 112 and a lens 113. The housing 111 is provided with a third clearance hole 119; the light source board 112 is arranged in the housing 111; the electrical connection structure 12 is arranged on the backlight surface of the light source board 112, and the electrical connection structure 12 passes through the third clearance hole 119; the lens 113 is located below the light source board 112 and is detachably connected to the housing 111.

[0091] The light source plate 112 is provided with a plurality of light sources for emitting light. The lens 113 is used to refract the light to increase the light emitting area.

[0092] The light source board 112 is limited in the housing 111 . Since the electrical connection structure 12 passes through the third clearance hole 119 and is plugged into the electric contact structure 22 , and the lens 113 is connected to the housing 111 , the light source board 112 can be stably limited in the housing 111 .

[0093] Specifically, the lens 113 includes a lens shell and a lens body. The lens shell is cylindrical, and a slider 117 is arranged on the outer peripheral surface. The lens body is arranged in the lens shell. The lens body is mainly used to refract light. The lens shell is used to arrange the lens body and is used to connect with the housing 111.

[0094] A slide groove 116 is provided on the outer circumferential surface of the housing 111, and the slide groove 116 has an inlet connected to the bottom surface of the housing 111. By rotating the lens 113, the slider 117 can slide into the slide groove 116 to fix the lens 113 to the housing 111. By rotating the lens 113 in the opposite direction, the slider 117 can slide to the inlet to separate the lens 113 from the housing 111, so as to facilitate the maintenance and replacement of the light source board 112. Preferably, a plurality of sliders 117 and slide grooves 116 are arranged at equal intervals along the circumference of the light source module 11.
