Description

Technical Field

[0001] The utility model relates to a novel downlight. Background Art

[0002] Chinese utility model patent specification CN2261553Y discloses a cold reflective glass downlight, including a lamp tube, a reflector and a decorative metal ring, wherein the reflector is fixed by a spring on the lamp tube and the decorative metal ring. However, this method of separating the spring from the decorative metal ring requires the decorative metal ring to be installed separately after the reflector is installed, which increases the assembly steps. Moreover, punching out the spring on the lamp tube will also increase the complexity of the structure and the difficulty of processing. Summary of the invention

[0003] The purpose of the utility model is to provide a new type of downlight, including a face ring, a lamp cup and a plurality of spring pieces, the front end of the lamp cup having a light outlet, the inner side of the face ring being provided with a supporting ring for supporting the front end of the lamp cup; all the spring pieces are mounted on the face ring, and all the spring pieces are circumferentially spaced around the axis of the face ring, and the spring pieces are configured to press the lamp cup.

[0004] The utility model arranges the supporting ring and the spring piece on the face ring at the same time, and the installation can be completed by directly pushing the lamp cup into the face ring from the top of the face ring. The utility model has a simple structure and is easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present application scheme is further described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 8 A novel downlight shown in the figure comprises a face ring 10, a lamp cup 20 and a plurality of spring pieces 30, wherein the front end 201 of the lamp cup has a light outlet;

[0023] The inner side of the face ring 10 is provided with a supporting ring 101 for supporting the front end 201 of the lamp cup;

[0024] All the spring pieces 30 are mounted on the face ring 10 , and all the spring pieces 30 are circumferentially spaced (especially equally spaced) around the axis of the face ring 10 . The spring pieces 30 are configured to press the lamp cup 20 .

[0025] The technical solution arranges the supporting ring and the spring piece on the face ring at the same time, and during installation, the lamp cup can be directly pushed into the face ring from above to complete the installation. The structure is simple and easy to disassemble and assemble.

[0026] The inner diameter d of the supporting ring is smaller than the outer diameter D of the front end of the lamp cup. The technical solution can limit the lamp cup in the axial direction of the face ring.

[0027] The spring pieces 30 are configured to push the front end 201 of the lamp cup against the supporting ring 101 when the lamp cup 20 is pressed. This technical solution enables the lamp cup to be stably and firmly clamped and fixed between the supporting ring and the spring pieces.

[0028] The face ring 10 is provided with a cylindrical face ring body 102 which is sleeved outside the front end 201 of the lamp cup. The face ring body plays a role in limiting the swing of the lamp cup. At the same time, the face ring body can surround the front end of the lamp cup to reduce side light leakage.

[0029] The support ring 101 is disposed on the inner side of the face ring cylinder 102;

[0030] All the spring pieces 30 are mounted on the face ring cylinder 102. The technical solution is reasonably designed and easy to produce.

[0031] The front end 201 of the lamp cup is cylindrical;

[0032] The face ring cylinder is sleeved outside the front end 201 of the lamp cup;

[0033] The inner diameter L of the face ring cylinder is equal to or greater than the outer diameter D of the front end of the lamp cup. The technical solution is reasonably designed and reduces the risk of the face ring and the lamp cup being separated from each other.

[0034] The novel downlight also includes a lamp holder 40 for mounting a light bulb (not shown in the figure);

[0035] The lamp cup 20 includes a cup body 202 and an electrical appliance mounting portion 203;

[0036] The front end of the cup body 202 is the front end 201 of the lamp cup, and the electrical installation part 203 is arranged at the rear end of the cup body 202;

[0037] The cup body 202 and the electrical appliance mounting portion 203 are integrated;

[0038] The lamp holder 40 is installed in the electrical installation portion 203;

[0039] The side wall of the electrical installation portion 203 is provided with a wire hole 204 for the wires (not shown) of the lamp holder 40 to pass through.

[0040] Chinese utility model patent specification CN202209642U discloses an anti-fog downlight with a face ring that can be easily disassembled, which includes a face ring, a bracket, a lamp holder and a lamp cup, the lamp holder is mounted on the bracket, and the lamp cup is mounted in the bracket. Each downlight of this structure cannot be stacked together during transportation, so a large transportation space is required.

[0041] The present technical solution eliminates the lamp stand and adds an electrical installation portion on the lamp cup for directly installing the lamp holder. On the one hand, eliminating the lamp stand can simplify the structure and save costs. On the other hand, the lamp cups can be stacked together (such as Fig. 9 As shown in the figure), this can greatly reduce the transportation space. When in use, you only need to take out the lamp cup and assemble it with the face ring, which is convenient and quick to assemble.

[0042] The lamp cup 20 is made of plastic, and the cup body 202 and the electrical appliance mounting portion 203 are integrally injection molded.

[0043] The side wall of the electrical installation part 203 is also provided with a heat dissipation through hole 205. The technical solution is to facilitate heat dissipation in the electrical installation part by providing the heat dissipation through hole.

[0044] The top of the lamp holder 40 is provided with a screw portion 401;

[0045] The end plate of the electrical installation part 203 is provided with an end plate through hole 206 for the screw part 401 to pass through;

[0046] The screw rod portion 401 is provided with a nut 50, and the nut 50 is screwed on the screw rod portion 401 passing through the end plate through hole to lock the lamp holder 40 in the electrical installation portion 203. This technical solution can facilitate the disassembly and assembly of the lamp holder and the lamp cup.
