Detailed Implementation

[0016] 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.

[0017] like Figures 1 to 4 As shown, an ultra-thin downlight according to this embodiment includes a lamp body 1, two torsion springs 2, a light source module 3, a drive module 4, and a glass shell 5.

[0018] The lamp body 1 includes a circular mounting plate 11. The center of the mounting plate 11 protrudes upward to form a hollow boss 12. The boss 12 has an open mounting groove 13 at the bottom. The peripheral wall of the boss 12 is provided with two symmetrically arranged torsion spring seats 14. The outer edge of the mounting plate 11 extends downward and outward to form an inclined skirt 15. The bottom of the skirt 15 extends horizontally outward to form a fixing plate 16. The inner inclined surface of the skirt 15 can be coated with a reflective material to form a reflective surface 17.

[0019] The angle between the reflective surface 17 of the inner slope of the skirt 15 and the mounting plate 11 can be greater than 110 degrees and less than 150 degrees. In this embodiment, 120 degrees is used as an example.

[0020] Two torsion springs 2 are respectively mounted on two torsion spring seats 14. The lower end of the torsion spring 2 can extend downwards outwards from the outside of the fixing plate 16 and is fitted with a torsion spring sleeve 21. Usually, the torsion spring 2 is made of metal, and the torsion spring sleeve 21 is made of plastic or silicone, etc.

[0021] The light source module 3 includes a light board 32 with a number of LED beads 31 evenly distributed on the bottom. The light board 32 is attached and locked to the bottom of the mounting plate 11.

[0022] The driving module 4 includes a small driving board 41, which is vertically mounted above the lamp plate 32 of the light source module 3 and located in the mounting groove 13 of the boss 12. The driving module 4 is electrically connected to the light source module 3. The height of the mounting groove 13 is no more than 15mm, that is, the height of the driving board 41 is no more than 12mm.

[0023] The glass shell 5 is spaced below the light source module 3, and its edge is snapped and fixed to the bottom periphery of the skirt 15. The distance between the top surface of the glass shell 5 and the light-emitting surface of the lamp bead 31 is 15-20mm, and 17mm is used as an example in this embodiment.

[0024] Therefore, the downlight of this embodiment has a thinner thickness and can be installed on low ceilings; the mounting plate 11 of the lamp body 1 is used to install and fix the lamp plate 32, and the inner side of the lamp body 1 has a protrusion 12 with a mounting groove 13 for accommodating a small drive module 4, which can reduce the height of the upper part of the lamp plate 32; the outer side of the lamp body 1 extends downward to form an inclined skirt 15, which can reduce the height of the lower part of the lamp plate 32. Moreover, the drive plate 41 is installed vertically and has a low height, and the distance between the lamp plate 32 and the glass shell 5 is small, which can reduce the overall thickness of the downlight and meet the installation requirements of low ceilings.

[0025] Meanwhile, the reflective surface 17 is directly formed on the inner slope of the skirt 15, which eliminates the need for a reflector cup structure, further reducing the product height, and ensuring the luminous effect. The reflective surface 17 has a large angle design of 120 degrees. 50% of the light from 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 17, it can be reflected by the reflective surface 17 and then penetrate the glass shell 5 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] During installation, two torsion springs 2 can be used in conjunction with a fixing plate 16 whose outer diameter is larger than the mounting hole for snap-fit ​​fixation. Of course, other installation structures can also be used for installation.

[0027] In this embodiment, the bottom of the skirt 15 is provided with an outer retaining ring 151, and the inner wall of the outer retaining ring 151 is recessed with several circumferentially spaced retaining holes 1511; 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 1511; the inner retaining ring 51 of the glass shell 5 is engaged with the inner side of the outer retaining ring 151 of the skirt 15, and each retaining block 511 is correspondingly embedded in each retaining hole 1511. The glass shell 5 can be completely fitted into the open position at the bottom of the skirt 15 without protruding outward, ensuring the thinness of the downlight.

[0028] In this example, the locking block 511 is a wedge-shaped protrusion with an inclined surface on the upper side and a flat surface on the lower side, so as to facilitate the upward locking and fixing of the glass shell 5.

[0029] In this embodiment, the downlight also includes a toggle switch 6, which is mounted on a vertically arranged drive plate 41. 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.

[0030] The top of the boss 12 is provided with a sliding hole 121 that passes through the mounting groove 13. The sliding hole 121 extends longitudinally and is located above the toggle switch 6. The sliding switch slider 7 can be slidably mounted in the sliding hole 121. 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 moved longitudinally by sliding the switch slider 7 longitudinally.

[0031] In this embodiment, the top of the boss 12 is recessed with a countersunk hole 122, and the middle of the countersunk hole 122 is provided with a sliding hole 121. The switch slider 7 can be longitudinally reciprocated and embedded in the countersunk hole 122. The switch slider 7 does not protrude outward, so as to reduce the overall height of the product.

[0032] A sealing groove 123 can be recessed around the outer periphery of the sliding hole 121 in the countersunk hole 122. The sealing groove 123 can be used to install the sealing ring 124. The top of the switch slider 7 has a sealing part 72. The sealing part 72 moves longitudinally along the countersunk hole 122 and covers the sealing ring 124 to improve the sealing, dustproof and moistureproof effect.

[0033] In this embodiment, the top of the mounting groove 13 may be provided with two spaced card seats 131, and the opposing surfaces of the two card seats 131 are respectively provided with card slots 132. The two ends of the drive plate 41 can be respectively engaged and fixed in the two card slots 132 to facilitate the mounting and fixing of the upper part of the drive plate 41.

[0034] In this embodiment, the drive board 41 includes a main board 411 and a sub-board 412, and two corresponding toggle switches 6 may be provided.

[0035] The main board 411 and the sub-board 412 are installed longitudinally spaced and perpendicular to the lamp board 32. The top of the corresponding mounting slot 13 can be provided with four card slots 131 to limit and lock the upper part of the main board 411 and the sub-board 412 respectively. A toggle switch 6 is installed and connected on the main board 411 and the sub-board 412 respectively. The two toggle switches 6 are spaced apart. The movement of the two levers 61 can be realized by the two switch sliders 7, which can control the color temperature, power and other functions respectively.

[0036] In this embodiment, the downlight also includes a power cord 8, which is electrically connected to the drive module 4. Specifically, the top of the mounting groove 13 may also be provided with a snap-fit ​​seat 133, and the bottom surface of the snap-fit ​​seat 133 forms a snap-fit ​​groove 134. The side wall of the boss 12 is provided with a power cord opening 125 that passes through the mounting groove 13, and the power cord opening 125 is located opposite the snap-fit ​​seat 133. The inner end of the power cord 8 is welded and fixed to the drive plate 41 of the drive module 4, and the inner end of the power cord 8 is also provided with a wire clip 81, which can be snapped into the snap-fit ​​groove 134. The outer end of the power cord 8 extends outward from the power cord opening 125. The power cord 8 is laterally arranged around the boss 12, which can also reduce the overall thickness of the downlight.

[0037] In this embodiment, the top of the mounting groove 13 may have several screw posts 135 protruding downwards. The screw posts 135 can be used in conjunction with connecting screws 136 to lock and fix the lamp panel 32, thereby improving the installation and locking effect.
