Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and in particular to an ultra-thin downlight structure. Background Technology

[0002] Downlights are ceiling-mounted lighting fixtures that project light downwards. They are typically installed around the perimeter of bedrooms and living rooms. Downlights can be divided into recessed downlights and surface-mounted downlights. Surface-mounted downlights usually protrude from below the ceiling, making them somewhat obtrusive and prone to being bumped or knocked over, and less convenient to use. Recessed downlights, on the other hand, require the internal installation of various components, resulting in a larger size. For locations with low ceilings, taller downlights may not meet the customer's need for recessed installation. Utility Model Content

[0003] The purpose of this utility model is to provide an ultra-thin downlight structure, which is thin and convenient for embedded installation in spaces with limited ceiling height.

[0004] To achieve the above objectives, the solution of this utility model is: An ultra-thin downlight structure includes a lamp body, two torsion springs, a light source module, a glass shell, and an external driving module; The lamp body includes a mounting plate, the outer edge of which extends downward and outward to form an inclined skirt, and a fixing plate extends horizontally outward from the bottom of the skirt; The inner side of the skirt forms an installation space; the outer wall of the skirt is provided with two torsion spring seats symmetrically distributed along the center of the skirt and a connecting hole communicating with the installation space; a reflective surface is formed on the inner inclined surface of the skirt; Two torsion springs are respectively installed on two torsion spring seats, with the lower ends of the torsion springs extending downwards beyond the outside of the fixing plate; The light source module includes a light panel with a number of LED beads evenly distributed on the bottom, and the light panel is attached to and installed in the installation space below the mounting plate. The glass shell is spaced below the light source module and its edge is snapped and fixed to the bottom periphery of the skirt; The drive module is externally mounted on the lamp body and is electrically connected to the light source module through a connecting wire passing through the connecting hole.

[0005] Furthermore, the top of the inner wall of the skirt, near the mounting plate, has several circumferentially spaced ribs that protrude inwards, with the top surfaces of the ribs spaced apart from the mounting plate to form fixing grooves; the edge of the lamp plate is snapped into each fixing groove.

[0006] Furthermore, the bottom surface of the mounting plate has several positioning protrusions; the lamp plate is provided with several pairs of positioning holes located on the positioning protrusions.

[0007] Furthermore, the bottom of the skirt is provided with an outer retaining ring, and the inner wall of the outer retaining ring is recessed with several circumferentially spaced retaining holes; the outer edge of the glass shell extends upward to form an inner retaining ring, and the outer wall of the inner retaining ring is provided with several retaining blocks corresponding to the retaining holes; the inner retaining ring of the glass shell is engaged with the inner side of the outer retaining ring of the skirt, and each retaining block is correspondingly embedded in each retaining hole.

[0008] Furthermore, the card block is a wedge-shaped protrusion with an inclined surface on the upper side and a flat surface on the lower side.

[0009] Furthermore, the reflective surface is composed of a reflective material coated on the inner slope of the skirt hem.

[0010] Furthermore, the thickness of the lamp body is 21mm ± 1mm.

[0011] Furthermore, the angle between the skirt reflective surface and the mounting plate is greater than 110 degrees and less than 150 degrees.

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 6 As shown, an ultra-thin downlight structure in this embodiment includes a lamp body 1, two torsion springs 2, a light source module 3, a glass shell 4, and an external driving module 5.

[0018] The lamp body 1 includes a circular mounting plate 11. The outer edge of the mounting plate 11 extends downward and outward to form an inclined skirt 12. A fixing plate 13 extends horizontally outward from the bottom of the skirt 12. The inclined skirt 12 facilitates the embedding and installation of the lamp body 1 in the ceiling, and the fixing plate 13 can be positioned below the pre-drilled hole in the ceiling.

[0019] The inner side of the skirt 12 forms an installation space 14, which can be used to install the light source module 3; the outer wall of the skirt 12 is provided with two torsion spring seats 15 symmetrically distributed along the center of the skirt 12 and a connecting hole 16 connected to the installation space 14; the connecting hole 16 is used to pass through the connecting wire 6.

[0020] A reflective surface 17 is formed on the inner inclined surface of the skirt 12, which can reflect light.

[0021] Two torsion springs 2 are respectively installed on two torsion spring seats 15. The lower end of the torsion spring 2 extends downward outward from the outside of the fixing plate 13 and is fitted with a torsion spring sleeve 21. Thus, when the lamp body 1 is installed into the ceiling hole, the two torsion springs 2 can be fixed above the ceiling.

[0022] Typically, the torsion spring 2 is made of metal, while the torsion spring sleeve 21 is made of plastic or silicone.

[0023] The light source module 3 includes a light plate 32 with a plurality of LED beads 31 evenly distributed on the bottom. The light plate 32 is attached to and installed in the mounting space 14 below the mounting plate 11. The close contact between the light plate 32 and the mounting plate 11 ensures heat dissipation.

[0024] The glass shell 4 is spaced below the light source module 3 and its edge is snapped and fixed to the bottom periphery of the skirt 12; the drive module 5 is externally disposed on the lamp body 1 and is electrically connected to the light source module 3 through the connecting line 6 passing through the connecting hole 16.

[0025] Therefore, in this embodiment, the driving module 5 is an external structure, and only the light source module 3 is installed in the installation space 14 of the lamp body 1, so that the overall height of the downlight can be controlled within the range of 21mm±1mm, and it has a thin thickness, which can be installed on a low ceiling, while the driving module 5 can be flexibly placed inside the ceiling.

[0026] Meanwhile, reflective material can be directly coated onto the inner slope of the skirt 12 to form a reflective surface 17, which eliminates the need for a reflective cup structure, further reduces the product height, and also ensures the luminous effect.

[0027] The angle between the reflective surface 17 of the skirt 12 and the mounting plate 11 is greater than 110 degrees and less than 150 degrees. 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 to reach the outside of the lamp. Through the uniform distribution of the beads 31 and the effect of the skirt reflective surface, the light emission of the lamp surface is uniform.

[0028] In this embodiment, the mounting plate 11 is circular, but it can also be rectangular or other shapes.

[0029] In this embodiment, the top of the inner wall of the skirt 12 near the mounting plate 11 may have several circumferentially spaced ribs 18 protruding inward, the top surface of the ribs 18 being spaced apart from the mounting plate 11 and forming a fixing groove 181; the edge of the lamp plate 32 may be snapped into each fixing groove 181.

[0030] Therefore, the lamp plate 32 can be easily snapped and fixed under the mounting plate 11 without the need for screws, that is, there is no need to set screw posts on the mounting plate 11, which can reduce the overall height of the product, save parts, and make installation more convenient.

[0031] Specifically, in this embodiment, the number of protruding ribs 18 is 4, but of course, it can also be 2 or 3, etc.

[0032] In this embodiment, the bottom surface of the mounting plate 11 also has a plurality of positioning protrusions 111. This embodiment takes two positioning protrusions 111 as an example. The lamp plate 32 is provided with a plurality of positioning holes 321 located on the positioning protrusions 111. Specifically, the lamp plate 32 may be provided with two positioning holes 321. Thus, the lamp plate 32 can be positioned and installed at the same time as it is snapped in.

[0033] 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 4 extends upward to form an inner retaining ring 41, and the outer wall of the inner retaining ring 41 is provided with several retaining blocks 411 corresponding to the retaining holes 122; the inner retaining ring 41 of the glass shell 4 is engaged with the inner side of the outer retaining ring 121 of the skirt 12, and each retaining block 411 is correspondingly embedded in each retaining hole 122. Thus, the glass shell 4 can be completely fitted into the open position at the bottom of the skirt 12 without protruding outward, ensuring the thinness of the downlight.

[0034] In this example, the locking block 411 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 4.

[0035] In this embodiment, the mounting plate 11 has a downward protruding mounting base 112 located in the mounting space 14. The mounting base 112 is located inside the connecting hole 16, and a mounting groove 113 connecting the connecting hole 16 is formed in the mounting base 112. The inner end of the connecting wire 6 is welded and fixed to the lamp board 32 of the light source module 3, and the inner end of the connecting wire 6 is also provided with a wire clip 61, which is snapped into the mounting groove 113. The outer end of the connecting wire 6 extends outward from the connecting hole 16 and is connected to the drive module 5.

[0036] This allows the inner end of the connecting wire 6 to be fixed to the connector 112 using the wire clip 61, preventing the connecting wire 6 from being pulled and detached from the electrical connection with the light source module 3, thus improving product reliability.
