[0033] Reference Figure 1 , Figure 2 and Figure 4 An assembled downlight includes a lamp holder 100, a face ring 200, and a power cord 300. The lamp holder 100 has a light source cavity 101 with an opening on the lower side, and a light source (not shown in the figure) is provided in the light source cavity 101. The face ring 200 is detachably connected to the lower side of the lamp holder 100 and is located at the opening of the light source cavity 101. One of the face ring 200 and the lamp holder 100 has a wire passage notch 102 for the power cord 300 to pass through. The power cord 300 can enter the light source cavity 101 through the wire passage notch 102 and be electrically connected to the light source. When the face ring 200 and the lamp holder 100 are connected and fixed, the upper side of the face ring 200 and the lower side of the lamp holder 100 can cooperate to clamp and fix the power cord 300.
[0034] Understandably, such as Figure 1 , Figure 2 and Figure 4As shown, the lamp holder 100 has symmetrical spring clips 120 for installation on both sides. The light source cavity 101 is located on the lamp holder 100 with its opening facing downwards. The face ring 200 is detachably connected to the lower side of the lamp holder 100 and located at the opening of the light source cavity 101. During production and assembly, before connecting and fixing the face ring 200 and the lamp holder 100, the power cord 300 enters the light source cavity 101 through the wire passage notch 102 and is electrically connected to the light source. Then, the face ring 200 and the lamp holder 100 are connected and fixed, using the upper and lower cooperation of the two to clamp and fix the power cord 300, so as to prevent the power cord 300 from loosening, thus completing the wire clamping operation. The above structure is simple and reasonable, which can eliminate the trouble of setting up a wire clamping block and its connecting components, which is conducive to saving production costs, and is convenient for assembly operations and production applications.
[0035] In practical applications, the specific structures of the lamp holder 100, face ring 200, and power cord 300 can be set according to actual usage needs, and will not be described in detail here. They will be explained in detail below.
[0036] In some embodiments, the wire notch 102 is provided on the side wall of the lamp holder 100, and the upper side of the face ring 200 is provided with a flange 210. The flange 210 is annular and located at the opening of the light source cavity 101, and can cooperate with the lamp holder 100 to clamp the power line 300 located at the wire notch 102.
[0037] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wire-passing notch 102 is located on the side wall of the lamp holder 100 and has an inverted "U" shape. The flange 210 is annular and located on the upper side of the face ring 200, extending inward relative to the face ring 200. During production and assembly, the power cord 300 enters the light source cavity 101 through the wire-passing notch 102 and is electrically connected to the light source. Then, the pressure ring is connected to the lamp holder 100, so that the flange 210 and the lamp holder 100 cooperate to clamp the power cord 300 located at the wire-passing notch 102, thereby achieving wire clamping and fixing. The flange 210 increases the wire clamping area, which helps to ensure the wire clamping effect. Its structure is simple and easy to use. In practical applications, the wire-passing notch 102 can also be located on the upper side of the face ring 200, which can be set according to the actual needs of use.
[0038] In some embodiments, a threaded member (not shown) is provided between the lamp holder 100 and the face ring 200. The threaded member passes through the flange 210 and is threadedly connected to the lamp holder 100 to press the flange 210 against the lower side of the lamp holder 100.
[0039] Understandably, such as Figure 2 , Figure 3 and Figure 4As shown, the flange 210 has holes for threaded parts to pass through, and the lamp holder 100 has corresponding threaded holes (not shown in the figure). During production and assembly, the threaded part passes through the flange 210 from bottom to top and engages with the threaded hole of the lamp holder 100, pressing the flange 210 against the lower side of the lamp holder 100. This achieves a detachable connection between the face ring 200 and the lamp holder 100, which is stable and reliable. This facilitates the pressing and fixing of the power cord 300 by the flange 210, and the design also helps to hide the threaded part, improving the aesthetics. In practical applications, the threaded part can be a bolt or screw. In addition to the above structure, the face ring 200 and the lamp holder 100 can also be detachably connected through a snap-fit structure, which can be set according to the actual needs of use.
[0040] In some embodiments, the flange 210 is provided with a connecting hole 201, which connects the light source cavity 101 and the external atmospheric environment of the lamp holder 100.
[0041] Understandably, such as Figure 3 and Figure 5 As shown, the flanged portion 210 is provided with a connecting hole 201, which is located on the side wall of the lamp holder 100. In use, the connecting hole 201 can be used to connect the light source cavity 101 and the external atmospheric environment of the lamp holder 100, which is beneficial to the heat dissipation of the light source cavity 101 and facilitates use. In actual applications, the specific structure and size of the connecting hole 201 can be set according to the actual needs of use.
[0042] In some embodiments, a limiting slot 103 is provided at the wire passage notch 102, and a limiting boss 310 is provided on the power cord 300. The limiting boss 310 is engaged in the limiting slot 103 to restrict the power cord 300 from being pulled out of the wire passage notch 102.
[0043] Understandably, such as Figure 2 , Figure 4 and Figure 6 As shown, a limiting slot 103 is provided at the wire passage notch 102, and a limiting boss 310 is integrally formed on the outside of the power cord 300. During production and assembly, the power cord 300 is moved from bottom to top and inserted into the wire passage notch 102, so that the limiting boss 310 is locked in the limiting slot 103, thereby restricting the power cord 300 from moving horizontally out of the wire passage notch 102 and achieving an anti-pull effect. Combined with the clamping of the power cord 300 by the flange 210 and the lamp holder 100, the power cord 300 can be well fixed and convenient to use. In actual applications, the specific structure of the limiting slot 103 and the limiting boss 310 can be set according to the actual use requirements.
[0044] In some embodiments, the modular downlight also includes a reflector 410, which is detachably connected to the face ring 200 via a snap-fit structure and located below the opening of the light source cavity 101.
[0045] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the reflector 410 is detachably connected to the face ring 200 via a snap-fit structure and is located below the opening of the light source cavity 101. Its connection method is simple, assembly is convenient, and it is easy to manufacture and apply. In practical applications, in addition to the above structure, the reflector 410 can also be connected to the face ring 200 or the lamp holder 100 via a threaded structure, depending on the specific application requirements.
[0046] In some embodiments, the modular downlight also includes a diffuser plate 420, which is detachably connected to the reflector cup 410 via a snap-fit structure and located below the opening of the light source cavity 101.
[0047] Understandably, such as Figure 2 , Figure 3 and Figure 5 As shown, the diffuser plate 420 is detachably connected to the upper side of the reflector cup 410 via a snap-fit structure and is located below the opening of the light source cavity 101. Its connection method is simple, and assembly is relatively convenient. When replacing the reflector cup 410 and the diffuser plate 420, the reflector cup 410 can be disassembled for overall replacement or replacement individually, facilitating use. In practical applications, in addition to the above structure, the diffuser plate 420 can also be connected to the reflector cup 410, the face ring 200, or the lamp holder 100 via a threaded structure, depending on the actual usage requirements.
[0048] In some embodiments, the reflector cup 410 is provided with a first hook portion 411, and the face ring 200 is provided with an annular groove 202 that engages with the first hook portion 411. The reflector cup 410 is provided with a supporting step 413 and a second hook portion 412 corresponding to the diffuser plate 420. The diffuser plate 420 is placed on the supporting step 413 and engages with the second hook portion 412.
[0049] Understandably, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the reflector cup 410 has three first hook portions 411, which are spaced apart circumferentially around the reflector cup 410. The upper side of the reflector cup 410 has a supporting step 413 and three second hook portions 412, which are also spaced apart circumferentially around the reflector cup 410. The inner side of the face ring 200 has an annular groove 202 opposite to the first hook portions 411. During production and assembly, the diffuser plate 420 is placed on the supporting step 413 and engaged with the second hook portions 412, thus connecting the diffuser plate 420 and the reflector cup 410. Then, both are placed together inside the face ring 200, allowing the first hook portions 411 to engage with the annular groove 202, achieving the installation connection of the reflector cup 410 and the diffuser plate 420 relative to the face ring 200. The assembly operation is convenient and easy to use. In practical applications, the snap-fit structure between the reflector cup 410 and the face ring 200, as well as the snap-fit structure between the diffuser plate 420 and the reflector cup 410, can be changed according to actual needs. For example, the first snap-fit part 411 can be placed on the face ring 200, and the second snap-fit part 412 can be placed on the diffuser plate 420, etc., which will not be elaborated here.
[0050] In some embodiments, the reflector cup 410 has an annular edge 414 on its lower side, and the face ring 200 has an annular step 220 on its lower side, with the annular edge 414 abutting against the annular step 220.
[0051] Understandably, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during production and assembly, the reflector cup 410 and the face ring 200 are snapped together and fixed. At this time, the annular edge 414 abuts against the annular step 220. This not only improves the stability of the connection and reduces the possibility of loosening, but also prevents light leakage from the outside of the reflector cup 410, ensuring the lighting effect. In practical applications, the annular edge 414 and the annular step 220 can be set according to the actual needs of use.
[0052] In some embodiments, the peripheral sidewalls of the light source cavity 101 are provided with reinforcing ribs 110. It is understood that, as... Figure 2 and Figure 6 As shown, the peripheral sidewall of the light source cavity 101 is provided with multiple reinforcing ribs 110. On the one hand, this strengthens the structural strength of the lamp holder 100 sidewall, ensuring its fit with the flange 210 and reducing the possibility of deformation. On the other hand, this structural design increases the heat dissipation area of the light source cavity 101, improving heat dissipation and facilitating use. In practical applications, the specific structure and number of reinforcing ribs 110 can be set according to actual usage needs.
[0053] Since the other components of the assembled downlight of this utility model embodiment are known to those skilled in the art, they will not be described in detail here.
[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
