Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] like Figures 1 to 6 As shown, a lamp according to an embodiment of the present invention includes a mounting base 1 and a lamp body 2.

[0031] Mounting bracket 1 can be installed on the ceiling to become a ceiling light, or it can be installed on the wall to become a wall light. It can be fixed to the ceiling or wall with screws. Mounting bracket 1 is equipped with an elastic conductive clip 3, which is connected to the mains power.

[0032] Optionally, the elastic conductive clip 3 includes an L-shaped connecting piece 31 and a clip body 32 connected to each other. The clip body 32 includes a first clip 321 and a second clip 322 disposed opposite to each other. Specifically, the first clip 321 is configured to be bent, consisting of a first raised portion 3211, a first contact portion 3212, a first inclined portion 3213 and a first connecting portion 3214 in sequence. The second clip 322 is configured to be bent, consisting of a second raised portion 3221, a second contact portion 3222, a second inclined portion 3223 and a second connecting portion 3224 in sequence. The first raised portion 3211 and the second raised portion 3221 are bent outwards to form a V-shaped guide opening, and the first contact portion 3212 and the second contact portion 3222 are opposite to each other to form a clamping portion. The first inclined portion 3213 and the second inclined portion 3223 are inclined towards each other to form a V-shaped clamp. The first connecting portion 3214 and the second connecting portion 4224 are respectively connected to the L-shaped connecting piece 31. The first connecting portion 3214 and the second connecting portion 4224 are arranged in parallel.

[0033] Specifically, the mounting base 1 is also equipped with a plug 4 and a spring piece 5. The plug 4 and the L-shaped connecting piece 31 form a limiting space with an opening on one side. The plug 4 has a wire groove 41 that connects to the first side of the L-shaped connecting piece 31. The wire groove 41 is used to insert the mains connection wire. The spring piece 5 is U-shaped and includes a base plate 51 and a first side plate 52 and a second side plate 53 located on both sides of the base plate 51. The second side plate 53 is in contact with the second side of the L-shaped connecting piece 31. The first side plate 52 elastically abuts against the plug 4, and a clamping space for holding the conductive wire is formed between the first side plate 52 and the first side of the L-shaped connecting piece 31. The first side plate 52 is inclined and arranged at an acute angle with the base plate 51, so that the first side plate 52 has good elastic clamping. The mains connection wire is inserted through the wire groove 41. With the help of the elasticity of the first side plate 52, the mains connection wire is clamped between the first side plate 52 and the first side of the L-shaped connecting piece 31, realizing the quick installation of the mains connection wire. After the mains power connection wire is connected to the spring 5, the spring 5 and the elastic conductive clip 3 form an electrical connection.

[0034] Furthermore, a fixing seat 11 is formed on the mounting base 1, and a plug 4, a spring piece 5, and an elastic conductive clip 3 are arranged sequentially from the inside to the outside in the fixing seat 11. There are two opposite mounting bases 1, and each mounting base 1 is provided with a plug 4, a spring piece 5, and an elastic conductive clip 3 arranged sequentially from the inside to the outside, which are respectively connected to the neutral wire and the live wire of the mains power.

[0035] The lamp body 2 is rotatably and detachably connected to the mounting base 1. The lamp body 2 is equipped with a light-emitting element 6 and a conductive contact 7. One end of the conductive contact 7 is connected to the light-emitting element 6, and the other end of the conductive contact 7 can be held by an elastic conductive clip 3 when the lamp body 2 is rotated. The conductive contact 7 connects the mains power to the light-emitting element 6. The light-emitting element 6 can be an LED light source board, which adopts a DOB (Digital Optical Layout) design and consists of three small circuit boards. The LED light source board is fixed to the lamp body 2 by thermal bonding.

[0036] Optionally, the lamp body 2 and the mounting base 1 are rotatably and detachably connected by a limiting rib and a limiting groove. Specifically, the mounting base 1 has a first limiting rib 12 along its circumferential direction, and a limiting groove 13 is formed between the first limiting rib 12 and the mounting base 1. The end of the first limiting rib 12 is adjacent to the elastic conductive clip 3; the starting end of the first limiting rib 12 has an inclined guide surface 121. The lamp body 2 has a second limiting rib 21 along its circumferential direction. The second limiting rib 21 can slide into the limiting groove 13. The sliding end of the second limiting rib 21 is adjacent to the conductive contact 7. When the second limiting rib 21 slides into the limiting groove 13, the conductive contact 7 slides into the elastic conductive clip 3.

[0037] Rotating the lamp body 2 causes the second limiting rib 21 to slide into the limiting groove 13 from the inclined guide surface 121 at the starting end of the first limiting rib 12, allowing the conductive contact 7 to slide into the first clamp 321 and the second clamp 322 of the elastic conductive clamp 3. Specifically, the conductive contact 7 slides between the first contact portion 3212 and the second contact portion 3222 to achieve conductivity. At this time, the second limiting rib 21 abuts against the first limiting rib 12 and is limited. When the lamp body 2 is rotated in the opposite direction, the conductive contact 7 slides out of the elastic conductive clamp 3, and simultaneously, the second limiting rib 21 slides out of the first limiting rib 12, allowing the lamp body 2 to be removed and replaced. To ensure a more stable installation, the first limiting rib 12 and the second limiting rib 21 are respectively set as two opposite ribs, with each rib 12 corresponding to the second limiting rib 21.

[0038] Furthermore, a first mounting ring 14 is formed axially on the mounting base 1, and a first limiting rib 12 is formed radially on the first mounting ring 14; a second mounting ring 22 is formed axially on the lamp body 2, and a second limiting rib 21 is formed radially on the second mounting ring 22. The width of the second limiting rib 21 matches the limiting groove 13 so that the second limiting rib 21 can slide into the limiting groove 13, while the lamp body 2 does not wobble relative to the mounting base 1.

[0039] Optionally, the conductive contact 7 is L-shaped, with one side of the L-shaped conductive contact 7 engaging with the elastic conductive clip 3, and the other side of the L-shaped conductive contact 7 passing through the lamp body 2 and connecting to the light-emitting element 6. Specifically, the lamp body 2 is provided with a pressure cap 8, which covers one side of the L-shaped conductive contact 7 to restrict the movement of the conductive contact 7.

[0040] According to an embodiment of the present invention, a lamp body 2 is rotatably and detachably connected to a mounting base 1 without disconnecting or connecting the power cord, making disassembly and assembly convenient. At the same time, the mounting base 1 is provided with an elastic conductive clip 3, and the lamp body 2 is also provided with a conductive contact 7. When the lamp body 2 is rotated, the conductive contact 7 can be clamped by the elastic conductive clip 3, so that the electrical connection between the conductive contact 7 of the lamp body 2 and the elastic conductive clip 3 of the mounting base 1 is stable and there is no poor contact.
