Description

Technical Field

[0001] This utility model relates to the field of downlight technology, and in particular to a downlight structure that is easy to assemble. Background Technology

[0002] In the field of lighting equipment, downlights are widely used in various lighting scenarios such as commercial venues and home decoration due to their characteristics of easy installation, concentrated light, and strong decorative appeal. The structure of a downlight mainly consists of a heat sink, a lampshade, a cover, and a light-emitting component installed inside the lampshade. The heat sink is used to dissipate the heat generated by the light-emitting component, ensuring the stable operation of the downlight; the lampshade protects the light-emitting component and controls the angle of light emission; the cover constitutes the appearance of the downlight and affects the overall visual effect.

[0003] Currently, most downlights on the market use bolts to connect the lampshade and the cover. While this method provides a certain degree of secure assembly, it has significant drawbacks. Because the bolts are constantly exposed to the outside of the lamp body, they are highly susceptible to corrosion due to prolonged exposure to moisture, dust, and other harsh environments. Corroded bolts negatively impact the downlight's appearance. Furthermore, excessive exposed bolts disrupt the overall simplicity and streamlined design of the downlight, failing to meet the high aesthetic and design requirements of modern users. Utility Model Content

[0004] The purpose of this utility model is to provide a downlight structure that is easy to assemble, addressing the shortcomings and deficiencies of the existing technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The present invention provides a simple downlight structure, which includes a heat sink housing, a face ring, a lampshade fixed on the heat sink housing, and a light-emitting module disposed inside the heat sink housing.

[0007] Both sides of the lampshade are provided with arc-shaped spring strips; the arc-shaped spring strips extend to the outside of the lampshade; two horizontal grooves are provided on the inner sidewall of the face ring; the horizontal grooves extend along the circumferential direction of the face ring; the two horizontal grooves are distributed in a circle on the face ring.

[0008] A groove is provided at one end of the inner bottom wall of the transverse groove; a straight groove is provided at the other end of the transverse groove; the straight groove extends to the top surface of the face ring.

[0009] After the two arc-shaped spring strips are inserted from the straight groove into the horizontal groove, they slide into the recess along the length of the horizontal groove.

[0010] The width of the horizontal groove is equal to the width of the curved spring bar.

[0011] Furthermore, through holes are provided on both sides of the lampshade; insertion holes are provided on the left and right side walls of the through holes; spring inserts are fixed at both ends of the arc-shaped spring strip; the spring inserts on both sides of the arc-shaped spring strip are respectively inserted into the insertion holes on both sides of the same through hole.

[0012] Furthermore, the arc-shaped spring strip is made of stainless spring steel bent into shape.

[0013] Furthermore, the depth of the transverse groove gradually decreases along the direction of the groove.

[0014] Furthermore, an annular groove is provided around the heat dissipation housing; multiple lampshade clips are provided on the inner side wall of the lampshade; the lampshade clips are engaged into the annular groove.

[0015] Furthermore, an insert is provided on the inner wall of the lampshade; a slot matching the insert is provided at the bottom of the heat dissipation housing; the insert is inserted into the slot.

[0016] Furthermore, the light-emitting module consists of a lens, a substrate, a light source, a light source bracket, and a reflector; the light source is fixed on the light source bracket; the light source is attached to the substrate; the lampshade is provided with a retaining ring; the retaining ring is pressed against the lens; the lens presses the reflector against the light source bracket; the substrate, the light source, and the light source bracket are fixed on the heat dissipation housing.

[0017] After adopting the above structure, the beneficial effects of this utility model are as follows: after the lampshade, heat dissipation housing and internal light-emitting module are assembled, the arc-shaped spring strips on both sides are aligned with the straight grooves on both sides, and then the arc-shaped spring strips are inserted into the horizontal grooves from top to bottom. Then the lampshade and heat dissipation housing are rotated relative to each other, and finally the outer surface of the arc-shaped spring strips is embedded into the grooves for fixation; the elastic deformation of the arc-shaped spring strips is pressed against the surface of the grooves.

[0018] In this structure, the lampshade and face ring are positioned using an arc-shaped spring strip, so the connecting parts are not exposed. Moreover, the assembly efficiency of the downlight is improved by using an insertion assembly method and elastic positioning. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1 to 6 As shown, the simple-to-assemble downlight structure of this utility model includes a heat dissipation housing 1, a face ring 3, a lampshade 2 fixed on the heat dissipation housing 1, and a light-emitting module disposed inside the heat dissipation housing 1.

[0032] Both sides of the lampshade 2 are provided with arc-shaped spring strips 10; the arc-shaped spring strips 10 extend to the outside of the lampshade 2; two horizontal grooves 302 are provided on the inner side wall of the face ring 3; the horizontal grooves 302 extend along the circumferential direction of the face ring 3; the two horizontal grooves 302 are circumferentially distributed on the face ring 3.

[0033] A groove 303 is provided at one end of the inner bottom wall of the transverse groove 302; a straight groove 301 is provided at the other end of the transverse groove 302; the straight groove 301 extends to the top surface of the face ring 3.

[0034] After the two arc-shaped spring strips 10 are inserted from the straight groove 301 into the horizontal groove 302, they slide along the length of the horizontal groove 302 into the recess 303.

[0035] The width of the transverse groove 302 is equal to the width of the arc-shaped spring strip 10; spring clips 4 are provided on both sides of the face ring 3; after the lampshade 2, heat dissipation housing 1 and the internal light-emitting module are assembled, the arc-shaped spring strips 10 on both sides are aligned with the straight grooves 301 on both sides, and then the arc-shaped spring strips 10 are inserted into the transverse groove 302 from top to bottom. Then the lampshade 2 and heat dissipation housing 1 are rotated relative to each other. Finally, the outer surface of the arc-shaped spring strip 10 is embedded into the groove 303 for fixation; the elastic deformation of the arc-shaped spring strip 10 is pressed against the surface of the groove 303.

[0036] In this structure, the lampshade 2 and the face ring 3 are positioned by the arc spring strip 10, so that the connecting parts are not exposed. Moreover, the assembly efficiency of the downlight is improved by using the insertion assembly method and elastic positioning.

[0037] In a preferred embodiment of this utility model, the lampshade 2 is provided with through holes 204 on both sides; the left and right side walls of the through holes 204 are provided with insertion holes 20401; the two ends of the arc-shaped spring strip 10 are fixed with spring inserts 1001; the spring inserts 1001 on both sides of the arc-shaped spring strip 10 are respectively inserted into the insertion holes 20401 on both sides of the same through hole 204.

[0038] The curved spring strip 10 is fixed in the through hole 204 by inserting both ends; this facilitates the installation of the curved spring strip 10 and the lampshade 2.

[0039] In a preferred embodiment of this utility model, the arc-shaped spring strip 10 is made of stainless spring steel bent into shape.

[0040] In a preferred embodiment of this utility model, the depth of the transverse groove 302 gradually decreases along the direction of the groove 303. When the arc-shaped spring strip 10 enters the straight groove 301, it is not compressed. However, due to the gradual decrease in the depth of the transverse groove 302, which is equivalent to a wedge-shaped surface, the arc-shaped spring strip 10 is gradually compressed as it slides in the transverse groove 302. Then, when the groove 303 is directly opposite the arc-shaped spring strip 10, the arc-shaped spring strip 10 is released and inserted into the groove 303. Since the depth of the groove 303 is deeper than the end of the transverse groove 302 near the groove 303, the arc-shaped spring strip 10 is not easy to come out of the groove 303. Moreover, with the structure of the gradually decreasing depth of the transverse groove 302, the assembly of the lampshade 2 and the face ring 3 can be completed without manually pressing the arc-shaped spring strip 10, and the assembly is more secure.

[0041] In a preferred embodiment of this utility model, an annular groove 102 is provided around the heat dissipation housing 1; multiple lamp cover buckles 201 are provided on the inner side wall of the lamp cover 2; the lamp cover buckles 201 are snapped into the annular groove 102; the connection between the heat dissipation housing 1 and the lamp cover 2 is fixed together by buckles, thereby improving the efficiency of disassembly and assembly.

[0042] In a preferred embodiment of this utility model, an insert 202 is provided on the inner side wall of the lampshade 2; a slot 101 matching the insert 202 is provided at the bottom end of the heat dissipation housing 1; the insert 202 is inserted into the slot 101.

[0043] Insert the insert 202 into the slot 101 to prevent the heat sink 1 from rotating on the lamp cover 2, thus completely fixing the heat sink 1 and the lamp cover 2.

[0044] In a preferred embodiment of this utility model, the light-emitting module comprises a lens 5, a substrate 6, a light source 7, a light source bracket 8, and a reflector 9; the light source 7 is fixed on the light source bracket 8; the light source 7 is attached to the substrate 6; the lampshade 2 is provided with a retaining ring 203; the retaining ring 203 presses against the lens 5; the lens 5 presses the reflector 9 against the light source bracket 8; the substrate 6, the light source 7, and the light source bracket 8 are fixed on the heat dissipation housing 1;

[0045] The substrate 6 and the light source 7 are not fundamentally different from the prior art, so they will not be described in detail. The substrate 6 is used to dissipate heat for the light source 7. When the heat dissipation housing 1 and the lampshade 2 are assembled, the lens 5 and the reflector 9 are pressed and positioned by the retaining ring 203, and the assembly structure is simple.

[0046] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
