[0024] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0025] like Figures 1-6The mounting structure of the shown down lamp reflector cup includes a lamp shell 1 and a reflector cup 2 arranged in the lamp shell 1. A support ring 3 for supporting and mounting a lamp plate 10 is arranged on the inner wall of the lamp shell 1. An annular groove 4 is arranged on the lower end wall of the support ring 3. The upper end edge of the reflector cup 2 vertically extends an insertion ring 5 which can be inserted into the annular groove 4. Mounting bosses 6 for mounting spring clip assemblies 11 are arranged on the left and right sides of the lamp shell 1. Positioning holes 7 which are communicated with the lamp shell 1 are arranged on the upper end of the mounting bosses 6. Positioning columns 8 which can be inserted into the positioning holes 7 are arranged on the reflector cup 2.

[0026] The support ring 3 arranged on the inner wall of the lamp shell 1 firstly provides a fixed support reference for the lamp plate 10. After the lamp plate is mounted on the support ring, the fixed layout of the down lamp light emitting core is formed. Meanwhile, the mounting bosses 6 on the left and right sides of the lamp shell 1 are used for assembling the spring clip assemblies 11 to complete the external fixed structure building required by the overall installation of the down lamp. The positioning holes 7 on the upper end of the mounting bosses are communicated with the inner part of the lamp shell to provide a precise interface for the positioning of the reflector cup.

[0027] The reflector cup 2 is inserted and matched with the annular groove 4 on the lower end wall of the support ring 3 through the insertion ring 5 which vertically extends on the upper end edge. During installation, the reflector cup is aligned with the inner direction of the lamp shell, and the insertion ring 5 is accurately inserted into the annular groove 4. The annular groove wraps around the insertion ring to limit the circumferential rotation of the insertion ring. At the same time, the positioning column 8 arranged on the reflector cup 2 is synchronously inserted into the positioning hole 7 of the mounting boss 6. The cooperation between the positioning column and the positioning hole forms secondary limiting to further limit the circumferential rotation and axial movement of the reflector cup. The ring-shaped cooperation between the insertion ring and the annular groove is complementary, and finally the stable installation of the reflector cup in the lamp shell is realized.

[0028] When the reflector cup 2 is disassembled, only a slight external force along the axial direction is needed to make the positioning column 8 separate from the positioning hole 7, so as to release the circumferential and axial limiting constraints. Then the reflector cup 2 can be pulled outwards, so that the insertion ring 5 is separated from the annular groove 4, and the disassembly of the reflector cup is completed. The whole process does not need to damage any component structure.

[0029] As shown in Figure 1 , Figure 4 , Figure 5 The position corresponding to the mounting boss 6 in the lamp shell 1 forms a guide limiting groove 21. A guide limiting block 22 which can be inserted into the guide limiting groove 21 is arranged on the reflector cup 2. The positioning column 8 is arranged on the guide limiting block 22.

[0030] In the process of installing the reflector cup, first, the guide limiting block 22 on the reflector cup 2 is aligned with the guide limiting groove 21 corresponding to the mounting boss 6 position in the lamp shell 1, the guide limiting groove forms a preliminary guide constraint to the guide limiting block, guides the reflector cup to advance along the correct installation direction, avoids deviation and misplacement during installation, and quickly positions the relative installation position of the reflector cup and the lamp shell.

[0031] Further, the upper end edges of the guide limiting block 22 and the positioning column 8 are provided with inclined angles, and the inclined angle structure plays a guiding and importing role in the early stage of assembly. When the guide limiting block 22 is aligned with the guide limiting groove 21 and the positioning column 8 is aligned with the positioning hole 7 and advances, the inclined angle can quickly guide the block and the column to enter the corresponding groove and hole position, avoid jamming caused by assembly deviation, reduce the alignment difficulty, and improve the assembly smoothness.

[0032] In the utility model, the guide limiting block 22, the positioning column 8 and the reflector cup 2 adopt an integrally formed plastic material.

[0033] Referring to Figure 6 As shown in the figure, the lower end edge of the reflector cup 2 horizontally extends outwardly with a flange 51, and the lower end edge of the lamp shell 1 abuts on the flange 51.

[0034] During the process that the reflector cup 2 advances to be installed in place, the flange 51 horizontally extending outwardly at the lower end edge of the reflector cup 2 moves synchronously until the lower end edge of the lamp shell 1 is completely abutted and fitted with the upper end surface of the flange 51. At this time, the flange forms axial support to the lamp shell, limits the reflector cup from advancing further into the lamp shell, accurately positions the axial installation depth of the reflector cup, and avoids interference between the reflector cup and the lamp plate caused by excessive assembly.

[0035] In the utility model, a face ring shell 71 is further arranged at the lower end of the lamp shell 1, the face ring shell 71 comprises a circular baffle 72, a limiting convex ring 73 is arranged at the inner side of the lower end of the circular baffle 72, the lamp shell 1 is arranged in the circular baffle 72 and is fixed through a plurality of second screws 74, and the flange 51 abuts on the limiting convex ring 73.

[0036] Further, a plurality of screw posts 81 are arranged on the circular baffle 72 in a circumferential direction, and a plurality of extension plates 82 corresponding to the screw posts 81 are arranged on the outer side of the lamp shell 1, and the second screw 74 is screwed with the screw post 81 after passing through the extension plate 82.

[0037] During installation, the circular baffle 72 of the face ring shell is aligned with the lower end of the lamp shell 1 and is sleeved, and the lamp shell 1 is placed inside the circular baffle 72; at this time, it is necessary to ensure that the screw posts 81 on the circular baffle 72 correspond one by one with the extension plates 82 on the outer side of the lamp shell, so as to provide a precise interface for subsequent fixation. After the face ring shell 71 is sleeved in place, the limiting convex ring 73 on the inner side of the lower end of the circular baffle 72 is completely abutted with the lower end surface of the flange 51 of the reflector cup 2, forming secondary axial limiting of the flange 51, further limiting the axial displacement of the reflector cup 2; then the second screw 74 is screwed with the screw post 81 of the face ring shell 71 after passing through the extension plate 82 of the lamp shell, and the face ring shell 71 and the lamp shell 1 are firmly fixed, and the fixing and restraint of the reflector cup 2 are indirectly strengthened through the limiting convex ring 73 of the face ring shell 71.

[0038] Referring to Figures 2-5 As shown in the figure, the upper end of the mounting boss 6 is also provided with a slot 61, and the spring clip assembly 11 includes a metal sheet 62 capable of being inserted into the slot 61 and a spring clip 63 provided on the metal sheet 62, and the outer side of the mounting boss 6 is screwed with a first screw 64 capable of locking the metal sheet 62.

[0039] The spring clip assembly 11 is composed of a metal sheet 62 and a spring clip 63 provided on the metal sheet 62, and the fixed connection of the metal sheet 62 and the spring clip 63 is completed first, and the assembled spring clip assembly is aligned with the mounting bosses 6 on the left and right sides of the lamp shell 1, so that the metal sheet 62 is accurately inserted into the slot 61 provided at the upper end of the mounting boss 6. The slot 61 limits and restrains the metal sheet 62 in the circumferential and radial directions, quickly completes the preliminary positioning of the spring clip assembly, ensures the accurate installation position of the spring clip assembly, and avoids deviation. After the metal sheet 62 is inserted into the slot 61, the pre-set through hole on the metal sheet 62 is accurately aligned with the installation position of the first screw 64, and then the first screw 64 is screwed from the outer side of the mounting boss 6, sequentially passing through the threaded hole of the mounting boss 6 and the through hole of the metal sheet 62, and is fastened through thread engagement, so that the metal sheet 62 is firmly locked in the slot 61, the spring clip assembly and the mounting boss 6 are firmly fixed, and the stable assembly of the spring clip assembly on the lamp shell is realized.
