Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] like Figures 1 to 6 As shown, a downlight structure in this embodiment includes a lamp body 1, a mounting bracket 2, a light source module 3, a driver module 4, and a glass shell 5; like Figure 2 and Figure 4 The lamp body 1 includes a circular mounting plate 11. The outer edge of the mounting plate 11 extends downward and expands outward to form an inclined skirt 12. The bottom edge of the skirt 12 is bent upward to form a side flange 13 surrounding the outer periphery of the mounting plate 11. Thus, the lamp body 1 of this embodiment has a thin cylindrical structure in appearance. The mounting plate 11 of this embodiment is circular, but it can also be rectangular or other shapes, and is not limited thereto.

[0020] A reflective surface 14 is formed on the inner inclined surface of the skirt 12; two snap-fit ​​interfaces 131 are provided on the inner wall of the side flange 13, which are symmetrically distributed along the center of the mounting plate 11; the mounting bracket 2 is detachably installed inside the side flange 13 above the middle part of the mounting plate 11, and the two ends of the mounting bracket 2 are respectively snapped into the two snap-fit ​​interfaces 131, and the top surface of the mounting bracket 2 does not extend beyond the upper edge of the side flange 13; the mounting bracket 2 can be hidden inside the side flange 13, which can meet the installation requirements of surface-mounted downlights.

[0021] The mounting plate 11 has a hollow boss 15 protruding on one side of the line connecting the two card interfaces 131. The top surface of the boss 15 does not extend beyond the upper edge of the side flange 13. The boss 15 has an open mounting groove 16 at the bottom. The light source module 3 is installed below the mounting plate 11. The drive module 4 is installed above the light source module 3 and located in the mounting groove 16 of the boss 15. The drive module 4 is electrically connected to the light source module 3. The glass shell 5 is spaced below the light source module 3 and fixed to the bottom of the skirt 12.

[0022] Therefore, the overall height of the downlight in this embodiment can be controlled within the range of 33mm ± 1mm, resulting in a thinner profile. The mounting bracket 2 can be concealed within the side flange 13, allowing for surface mounting of the downlight in low-ceilinged locations. The mounting plate 11 of the lamp body 1 is used to mount and fix the light source module 3. A boss 15 with a mounting groove 16 protrudes from the inner side of the lamp body 1. The mounting groove 16 accommodates a small drive module 4. Simultaneously, the boss 15 is located on one side of the mounting bracket 2, and neither protrudes beyond the side flange 13, thus reducing the height of the upper part of the lamp body 1. An inclined skirt 12 extends downwards from the outer side of the lamp body 1, further reducing the height of the lower part of the lamp body 1. The distance between the light source module 3 and the glass shell 5 is also smaller, thereby reducing the overall thickness of the downlight. This meets the installation requirements for low-ceilinged locations, prevents damage from impacts, and ensures the product's aesthetic appeal.

[0023] At the same time, a reflective surface 14 can be formed directly on the inner slope of the skirt 12, which can eliminate the need for a reflector cup structure, further reduce the product height, and ensure the luminous effect.

[0024] like Figure 4 The light source module 3 includes a lamp plate 32 with a plurality of LED beads 31 evenly distributed on the bottom. The lamp plate 32 is attached and locked to the bottom of the mounting plate 11. The driving module 4 includes a driving plate 41, which is vertically mounted above the lamp plate 32 of the light source module 3 and located in the mounting groove 16 of the boss 15.

[0025] The angle between the reflective surface 14 of the inner slope of the skirt 12 and the mounting plate 11 can be greater than 110 degrees and less than 150 degrees. In this embodiment, the reflective surface 14 can be designed with a large angle of 120 degrees. 50% of the light in the LED beads 31 is within the 120-degree angle range. The light emitted by the beads 31 within the 120-degree range passes directly through the glass shell to the outside of the lamp. When the light outside the 120-degree range shines on the reflective surface, it can be reflected by the reflective surface and then penetrate the glass shell to reach the outside of the lamp. The uniform distribution of the beads 31 and the effect of the skirt reflective surface achieve uniform light emission on the surface of the lamp.

[0026] The downlight also includes a toggle switch 6; the toggle switch 6 is mounted on a vertically arranged drive plate 41, and the lever 61 of the toggle switch 6 extends laterally and can move longitudinally; by toggling the lever 61, the power or color temperature of the light source module 3 can be adjusted.

[0027] See Figure 5The top of the boss 15 is provided with a sliding hole 151 that passes through the mounting groove 16. The sliding hole 151 extends longitudinally and is located above the toggle switch 6. The sliding hole 151 can slide and mount the switch slider 7 longitudinally. The bottom of the switch slider 7 has a transversely through inverted "U"-shaped opening groove 71. The opening groove 71 is used for the lever 61 of the toggle switch 6 to engage. Thus, the lever 61 can be driven to move longitudinally by sliding the slider of the toggle switch 6 longitudinally.

[0028] In this embodiment, the top of the boss 15 is recessed with a countersunk hole 152, and the middle of the countersunk hole 152 is provided with a sliding hole 151. The switch slider 7 is longitudinally reciprocatingly fitted into the countersunk hole 152; the switch slider 7 does not protrude outward, so as to reduce the overall height of the product.

[0029] A sealing groove 153 is recessed around the outer periphery of the sliding hole 151 in the countersunk hole 152. A sealing ring 154 is installed in the sealing groove 153. The top of the switch slider 7 has a sealing part 72. The sealing part 72 moves longitudinally along the countersunk hole 152 and covers the sealing ring 154 to improve the sealing, dustproof and moistureproof effect.

[0030] See Figure 6 In this embodiment, the top of the mounting groove 16 has two spaced card seats 161 protruding downwards, and the opposing surfaces of the two card seats 161 are respectively recessed with card slots 162. The two ends of the drive plate 41 are respectively engaged and fixed in the two card slots 162 to facilitate the mounting and fixing of the drive plate 41.

[0031] In this embodiment, the downlight also includes a power cord 8, which is electrically connected to the drive module 4; a snap-fit ​​seat 163 protrudes from the top of the mounting groove 16, and a snap-fit ​​groove 164 is formed on the bottom surface of the snap-fit ​​seat 163; a power cord opening 155 through the mounting groove 16 is provided on the side wall of the boss 15 near the center of the mounting plate 11, and the power cord opening 155 is located opposite the snap-fit ​​seat 163; the inner end of the power cord 8 is welded and fixed to the drive plate 41 of the drive module 4, and a wire clip 81 is also provided at the inner end of the power cord 8, which is snapped into the snap-fit ​​groove 164, and the outer end of the power cord 8 extends outward from the power cord opening 155.

[0032] In this embodiment, the bottom of the skirt 12 is provided with an outer retaining ring 121, and the inner wall of the outer retaining ring 121 is recessed with several circumferentially spaced retaining holes 122; the outer edge of the glass shell 5 extends upward to form an inner retaining ring 51, and the outer wall of the inner retaining ring 51 is provided with several retaining blocks 511 corresponding to the retaining holes 122; the inner retaining ring 51 of the glass shell 5 is engaged with the inner side of the outer retaining ring 121 of the skirt 12, and each retaining block 511 is correspondingly embedded in each retaining hole 122. The glass shell 5 can be completely fitted into the open position at the bottom of the skirt 12 without protruding outward, ensuring the thinness of the downlight. The retaining block 511 is a wedge-shaped protrusion with an inclined surface on the upper side and a flat surface on the lower side, to facilitate the upward clamping and fixing of the glass shell 5.

[0033] In this embodiment, the bottom of the skirt 12 extends horizontally outward to form a fixing plate 17, and the outer edge of the fixing plate 17 bends upward to form the side flange 13; the top width of the side flange 13 is greater than the bottom width, thus exhibiting an outward expansion at the top. The outward expansion of the top of the side flange 13 facilitates its snap-fit ​​engagement with the mounting bracket 2.

[0034] In this embodiment, the mounting bracket 2 can be made of resin material and includes a long strip connecting plate 21 and two spring clips 22. The long strip connecting plate 21 is provided with a plurality of strip-shaped mounting holes 211 distributed along the length direction. When the downlight is installed, the long strip connecting plate 21 can be pre-locked to the ceiling by using the strip-shaped mounting holes 211 and screws.
