[0051] In order to make the technical problem, technical solution, and beneficial effects to be solved by the present application clearer and more understandable, the following will provide further detailed explanations of the present application 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 application and are not intended to limit the present application.
[0052] Please refer to Figures 1, 2, 6, 7, and 10 together to explain a downlight provided in the embodiments of the present application. The downlight includes a light body 1 and a driving assembly 2. The light body 1 includes a light source module 11 inside; the light source module 11 is provided with an electrical connection structure 12; the driving assembly 2 is arranged on a backlight surface of the light body 1; the driving assembly 2 includes a driving module 21 inside, and the driving module 21 is provided with an electrical contact structure 22; where the electrical connection structure 12 sequentially passes through the light body 1 and the driving assembly 2, and is matched with the electrical contact structure 22 by a plugging connection and electrically connected with the electrical contact structure 22.
[0053] The driving assembly 2 may be detachably connected with the light body 1 for easy replacement of the driving assembly 2 or the light source module 11 inside the light body 1. Specifically, the driving assembly 2 may be connected with the light body 1 through at least one of a snap-fit connection structure, a plugging-in structure, or a screw connection structure, or the driving assembly 2 may be placed on the backlight surface of the light body 1 and supported by the light body 1, and the two may be connected only by plugging the electrical connection structure 12 and the electrical contact structure 22. Of course, there may also be a fixed connection between the driving assembly 2 and the light body 1.
[0054] The electrical connection structure 12 and the electrical contact structure 22 are both charged bodies, which are plugged in and conduct when powered on, thereby achieving conductivity between the driving module 21 and the light source module 11. The electrical connection structure 12 is directly fixed to the light source module 11 without the need for connecting wires, and the electrical contact structure 22 is directly fixed to the driving module 21 without the need for connecting wires.
[0055] Before installing the downlight provided in this embodiment on the ceiling, the driving assembly 2 may be connected with the light body 1 first, and then assembled as a whole on the ceiling. Alternatively, the light body 1 may be assembled onto the ceiling first, and then the driving assembly 2 may be installed onto the backlight surface of the light body 1.
[0056] The beneficial effect of the downlight provided by embodiments of the present application is that, compared with the prior art, the driving assembly 2 is directly arranged on the backlight surface of the light body 1, and the driving assembly 2 is fixed by the light body 1, reducing the occupied space of the downlight; the light source module 11 of the light body 1 is configured with an electrical connection structure 12, and the driving module 21 of the driving assembly 2 is configured with an electrical contact structure 22; the electrical connection structure 12 is matched with the electrical contact structure 22 by a plugging connection and is electrically connected with the electrical contact structure 22. The driving module 21 can be connected with the light source module 11 without the need for wires, and the plugging operation is simple and fast, simplifying the installation operation of the downlight and eliminating safety hazards.
[0057] In some embodiments, the above-mentioned electrical connection structure 12 and electrical contact structure 22 may adopt the structures shown in Figures 2, 7, and 10, as shown in Figures 2, 7, and 10, the electrical connection structure 12 is a retractable terminal, and the electrical contact structure 22 is an electrical contact hole; and specifically, the light body 1 is provided with a first giving way hole 131, and the driving assembly 2 is provided with a second giving way hole 231; and the first giving way hole 131, the second giving way hole 231 and the electrical contact hole correspond axially.
[0058] The retractable terminal is welded and fixed on the light source module 11. The retractable terminal passes through the electrical contact hole and contacts the hole wall of the electrical contact hole, thereby achieving conductive connection. Specifically, according to the requirements of conductive connection, there are two sets of retractable terminals welded on the light source module 11, with a total of three retractable terminals in each set. Correspondingly, there are two sets of electrical contact holes on the driving module 21, with a total of three electrical contact holes in each set. The aperture of the electrical contact hole is compatible with the outer diameter of the retractable terminal. Of course, in order to accommodate different sizes of electrical contact holes, the plugging end of the retractable terminal may be designed as a conical structure.
[0059] The conductive connection is achieved by plugging the retractable terminal and the electrical contact hole, simplifying the structure of the light source module 11 and the driving module 21, and saving the cost of the downlight.
[0060] In addition, the aperture of the first giving way hole 131 and the aperture of the second giving way hole 231 are adapted to the external dimensions of each set of retractable terminals. For example, if the number of each set of retractable terminals is three and the three retractable terminals are arranged side by side, the first giving way hole 131 may be designed as a bar-shaped hole or a waist-shaped hole, and the length dimension of the first giving way hole 131 may be adapted to the length of a set of retractable terminals. The width dimension of the first giving way hole 131 may be adapted to the outer diameter of one retractable terminal, and the same size form may be applied to the second giving way hole 231.
[0061] Due to the size of the first giving way hole 131 and the second giving way hole 231 being compatible with the retractable terminal, the aperture of the first giving way hole 131 and the second giving way hole 231 can be correspondingly reduced to meet the fire protection requirements of the entire downlight.
[0062] In addition, in order to limit the extension direction of the retractable terminal, a limit platform can be set above the first giving way hole 131 and / or the second giving way hole 231. The limit platform has the same number of through holes as a set of retractable terminals, and the diameter of the through hole is adapted to the outer diameter of the retractable terminal.
[0063] In some embodiments, the above-mentioned retractable terminal may adopt the structure shown in Figure 3, as shown in Figure 3, the retractable terminal includes a fixed base 121, an elastic body 122 and a pogo pin 123. The fixed base 121 is fixedly arranged on the light source module 11; the fixed base 121 is provided with a receiving cavity; the elastic body 122 is arranged in the receiving cavity; one end of the elastic body 122 is in contact with a cavity wall of the receiving cavity; and one end of the pogo pin 123 is limited in the receiving cavity and in contact with the other end of the elastic body 122, and the other end of the pogo pin 123 is plugged into the electrical contact hole.
[0064] The receiving cavity has a cavity opening facing the electrical contact hole, and the elastic body 122 is completely placed inside the receiving cavity. One end of the pogo pin 123 is disposed in the receiving cavity from the cavity opening, and the other end extends out of the receiving cavity. The elastic body 122 has elastic degree of freedom along the axial direction of the electrical contact hole.
[0065] The elastic body 122 can provide a pre tension to the pogo pin 123, ensuring that the plugging end of the pogo pin 123 is plugged and passes through the electrical contact hole, and enabling the light source module 11 to adapt to different driving modules 21, reducing the influence of the tolerance of plugging fit of the retractable terminal and the electrical contact hole.
[0066] In some embodiments, the above-mentioned light body 1 and driving assembly 2 may adopt the structure shown in Figures 1, 4 and 5, as shown in Figures 1, 4 and 5, the backlight surface of the light body 1 is provided with a connection lug 15, the connection lug 15 is located on a periphery of the driving assembly 2, and the connection lug 15 is provided with a snap-fit opening 151; and an outer wall of the driving assembly 2 is provided with a snap-fit block 241, and the snap-fit block 241 is snapped inside the snap-fit opening 151.
[0067] The connection lug 15 extends upward relative to the light body 1 to surround the periphery of the driving assembly 2. The connection lug 15 is not only detachable from the driving assembly 2, but also used to set up a spring arm. The downlight is fixed to the ceiling using spring arms.
[0068] Specifically, there are two sets of symmetrically distributed connection lugs 15, each set of which is configured with a spring arm and a snap-fit opening 151. There are two sets of snap-fit blocks 241 corresponding to the outer wall of driving assembly 2.
[0069] The snap-fit block 241 has a degree of freedom to move radially inward along the downlight, so the interior of the driving assembly 2 has an avoidance space for avoiding slight inward movement of the snap-fit block 241. Specifically, when the snap-fit block 241 is loaded into the snap-fit opening 151, the driving assembly 2 is fixed to the light body 1. When manually pinching the snap-fit block 241 radially inward, the snap-fit block 241 can detach from the snap-fit opening 151, and then manually pulling the driving assembly 2 axially outward can separate the driving assembly 2 from the light body 1.
[0070] The two sets of connection lugs 15 not only serve to fix the spring arm to fix the downlight, but also to limit the driving assembly 2 to ensure the stable fixing state of the driving assembly 2 and the light body 1 after the assembly of the downlight. Moreover, the disassembly and assembly of the connection lug 15 and the driving assembly 2 is convenient, making it easy to replace the driving assembly 2.
[0071] In some embodiments, the above-mentioned driving assembly 2 may adopt the structure shown in Figure 10, as shown in Figure 10, the driving assembly 2 includes a base 23, the driving module 21 and a cover body 24. The driving module 21 is arranged on the base 23; and the cover body 24 is fastened on the base 23, and the cover body 24 covers a periphery of the driving module 21.
[0072] The base 23 is used to fix and support the driving module 21, as well as to achieve insulation isolation from the outer surface of the light body 1. The cover body 24 is used to shield the driving module 21. The cover body 24 and the base 23 enclose a closed space, and the driving module 21 is confined within the aforementioned closed space.
[0073] Specifically, two sets of snap-fit blocks 241 are set on the outer peripheral wall of the cover body 24. The second giving way hole 231 is set on the base 23.
[0074] In order to achieve a stable connection between the base 23 and the driving module 21, the base 23 is provided with a positioning column 232, the driving module 21 is provided with a positioning hole 211, and the positioning column 232 is matched with the positioning hole 211 by a plugging connection; and the base 23 is provided with a second hook 233, and the second hook 233 is in contact with the driving module 21 vertically.
[0075] The positioning column 232 is matched with the positioning hole 211 by the plugging connection to limit the circumferential position of the base 23 and the driving module 21. The hook surface of the second hook 233 is in contact with the board surface of the driving module 21 vertically, used to limit the upper position and the lower position of the driving module 21, thereby ensuring stable assembly of the driving module 21 and the base 23.
[0076] In some embodiments, the above-mentioned light body 1 may adopt the structure shown in Figure 7, as shown in Figure 7, the light body 1 includes a light shielding surface ring 13, the light source module 11 and a decorative surface ring 14. The light emitting surface of the light shielding surface ring 13 is an opening surface; the driving assembly 2 is arranged on a backlight surface of the light shielding surface ring 13; the light source module 11 is arranged inside the light shielding surface ring 13; and the decorative surface ring 14 is arranged on a bottom surface of the light shielding surface ring 13, and the decorative surface ring 14 is detachably connected with the light shielding surface ring 13.
[0077] Specifically, the light shielding surface ring 13 includes a cylindrical portion with an inner cavity and an open bottom surface, and a circular ring plate integrally formed on the outer periphery of the bottom surface of the cylindrical portion. The cylindrical portion is mainly used for installing the light source module 11, and the circular ring plate is mainly used for detachable connection with the decorative surface ring 14. Two sets of connection lugs 15 are set on the backlight surface of the light shielding surface ring 13.
[0078] Due to the limitations of the structure of the light shielding surface ring 13 and the assembly requirements with the light source module 11, the bottom surface of the circular ring plate is not a complete plane and has a groove structure. In order to shield the circular ring plate, the decorative surface ring 14 is also installed on the bottom surface of the circular ring plate, thus giving the downlight a good appearance effect.
[0079] The decorative surface ring 14 is detachably connected with the light shielding surface ring 13. After removing the decorative surface ring 14, the light source module 11 can be replaced. Replacing the light source module 11 separately can reduce maintenance costs. Specifically, the decorative surface ring 14 and the light shielding surface ring 13 can be detachably connected through at least one of a snap-fit connection structure, a screw structure, or a plugging-in structure.
[0080] For the convenience of manual disassembly of the decorative surface ring 14 and the light source module 11, please refer to Figures 2, 7, and 8. Based on the above embodiments, an outer peripheral wall of the light shielding surface ring 13 is uniformly provided with multiple sets of strip-shaped convex edges 132, and the multiple sets of strip-shaped convex edges 132 are equidistantly distributed along a circumferential direction of the light shielding surface ring 13; an outer peripheral wall of the light source module 11 is provided with a sinking groove 114, the sinking groove 114 is provided with a limiting block 115 inside, and a giving way distance exists between the limiting block 115 and one sidewall of the sinking groove 114; an inner peripheral wall of the decorative surface ring 14 is provided with convex blocks 141 that correspond one-to-one with the multiple sets of strip-shaped convex edges 132, the circumferential length of the convex block 141 is smaller than the circumferential length of strip-shaped convex edge 132, and a top surface of the decorative surface ring 14 is provided with a first hook 142.
[0081] Where the decorative surface ring 14 has a fixed position, a first disassembly position and a second disassembly position; when in the fixed position, the convex blocks 141 are in contact with corresponding strip-shaped convex edges 132 vertically; when in the first disassembly position, the convex blocks 141 are circumferentially misaligned with the corresponding strip-shaped convex edges 132, and the first hook 142 is in contact with the limiting block 115 vertically; and when in the second disassembly position, the convex blocks 141 are circumferentially misaligned with the corresponding strip-shaped convex edges 132, and the first hook 142 is located in the giving way distance.
[0082] Specifically, the strip-shaped convex edges 132 are set on the outer peripheral surface of the circular ring plate of the light shielding surface ring 13, and distributed at equal intervals along the circumferential direction. The convex blocks 141 are set on the inner peripheral surface of the decorative surface ring 14, and the first hook 142 is set on the top surface of the decorative surface ring 14. At least two sets of the first hooks 142 are set at equal intervals along the circumferential direction of the decorative surface ring 14. The sinking groovesl 14 and the limiting blocks 115 correspond one-to-one with the first hooks 142.
[0083] The decorative surface ring 14 can switch between a fixed position, a first disassembly position, and a second disassembly position by rotating. When rotating to the point where the convex blocks 141 and the strip-shaped convex edges 132 are in contact vertically (i.e., when the lower surface of each convex block 141 is in contact with the upper surface of each strip-shaped convex edge 132), the upper and lower limits of the convex blocks 141 and the stripshaped convex edges 132 are in place, and the decorative surface ring 14 is in the fixed position and cannot be separated from the light shielding surface ring 13.
[0084] When the convex blocks 141 are rotated away from the corresponding strip-shaped convex edges 132, and the first hook 142 is in contact with the upper surface of the limiting block 115 vertically (the hook surface of the first hook 142 is in contact with the upper surface of the limiting block 115), the decorative surface ring 14 is in the first disassembly position. There is no limit between the decorative surface ring 14 and the light shielding surface ring 13, 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 light shielding surface ring 13, achieving the disassembly of the light source module 11.
[0085] It should be noted that due to the plugging connection of the electrical connection structure 12 and the electrical contact structure 22, manually pulling the decorative surface ring 14 can overcome the plugging force between the electrical connection structure 12 and the electrical contact structure 22, causing them to detach.
[0086] When the convex blocks 141 disengages from the corresponding strip-shaped convex edges 132, and the first hook 142 is located within the giving way distance, the decorative surface ring 14 is in the second disassembly position. There is no limit between the decorative surface ring 14 and the light shielding surface ring 13, nor between the decorative surface ring 14 and the light source module 11. By pulling the decorative surface ring 14, it can be disassembled separately.
[0087] By making the decorative surface ring 14 and the light shielding surface ring 13 detachable, and adding a connection between the decorative surface ring 14 and the light source module 11, the decorative surface ring 14 has a dual effect of being disassembled separately and together with the light source module 11, which facilitates maintenance or replacement of the light source module 11 and meets the different disassembly and assembly needs of users.
[0088] In one embodiment, in the rotation axis, 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 convex points can be set in the sinking groove 114. The first convex point is located above the limiting block 115 (corresponding to the first disassembly position), the second convex point is located within the giving way distance and close to the side wall of the limiting block 115 (corresponding to the second disassembly position), and the third convex point is located near the side wall of the sinking groove 114 (corresponding to the fixed position). Of course, only the first convex point and the second convex point can be set, and the third convex point can be omitted.
[0089] In another embodiment, the fixed position is located between the first disassembly position and the second disassembly position in the rotational direction. When switching from the fixed position to the first disassembly position, the decorative surface ring 14 can be rotated counterclockwise. When switching from the fixed position to the second disassembly position, the decorative surface ring 14 can be rotated clockwise. By limiting the different rotation directions, the first disassembly position and the second disassembly position can be clearly indicated to the user.
[0090] In some embodiments, the above-mentioned light source module 11 may adopt the structure shown in Figures 2, 5, 6, and 8, as shown in Figures 2, 5, 6, and 8, the light source module 11 includes a housing 111, a light source plate 112 and a lens 113. The housing 111 is provided with a third giving way hole 119; the light source plate 112 is arranged inside the housing 111; the electrical connection structure 12 is arranged on a backlight surface of the light source plate 112, and the electrical connection structure 12 passes through the third giving way hole 119; and the lens 113 is located below the light source plate 112, and the lens 113 is detachably connected with the housing 111.
[0091] There are multiple light sources on the light source plate 112 for emitting light. The lens 113 is used to refract light to increase the light output area.
[0092] The light source plate 112 is limited within the housing 111. Due to the electrical connection structure 12 passing through the third giving way hole 119 and being plugged into the electrical contact structure 22, and the lens 113 being connected with the housing 111, the light source plate 112 can be stably limited within the housing 111.
[0093] Specifically, the lens 113 includes a lens housing and a lens body. The lens housing is cylindrical in shape, and a sliding block 117 is provided on the outer peripheral surface of the lens housing; and the lens body is set inside the lens housing. The lens body is mainly used to refract light, and the lens housing is used to set the lens body and connect with the housing 111.
