Description

TECHNICAL AREA

[0001] The present utility model relates to the technical field of lighting devices, in particular a lamp. STATE OF THE ART

[0002] In related technologies, luminaires such as ceiling or wall lights are designed as single units, which makes replacing them relatively cumbersome. Replacing existing luminaires like ceiling or wall lights requires a complete disassembly and reassembly process. Specifically, the power cables of the old luminaire must first be disconnected for safety reasons, followed by, among other things, removing the screws of the old luminaire, connecting the power cables of the new luminaire, and screwing the new luminaire into place. This constitutes a complete disassembly and reassembly process, making the installation cumbersome and complex.

[0003] To solve the aforementioned problem of cumbersome disassembly and assembly, a novel rotatable ceiling light, comprising a base and a luminaire cover, was published in patent specification CN205824793U. A connector is provided at the lower end of the base. A fluorescent tube is removably installed in the luminaire cover, and an electrical connection unit is provided at the upper end of the luminaire cover. This unit contacts and connects to the connector to link the fluorescent tube to a driver. An L-shaped connecting element extends downward from the lower end of the base, and an arcuate mounting groove is provided at the upper end of the luminaire cover, which engages with the L-shaped connecting element. By rotating the luminaire cover, the L-shaped connecting element engages in the arcuate mounting groove and is thus locked in place.

[0004] However, the contact and connection between the socket's connector and the electrical connection unit of the light cover in the aforementioned swivel ceiling light result in an insufficiently stable electrical connection, which can easily lead to poor contact. Furthermore, the locking mechanism, caused by the L-shaped connector snapping into the arc-shaped mounting groove, tends to loosen, resulting in an unstable connection.

[0020] To better understand the technical solutions described above, exemplary embodiments of the present utility model are discussed in more detail below with reference to the accompanying drawings. Although the accompanying drawings represent exemplary embodiments of the present utility model, it is understood that the present utility model can be implemented in various forms and should in no way be limited by the embodiments explained here. Rather, such embodiments serve to provide a more thorough understanding of the present utility model, thus fully conveying its scope to those skilled in the art.

[0021] As in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig.As shown in Figure 6, a luminaire according to an embodiment of the present utility model comprises a mounting base 1 and a luminaire body 2.

[0022] The mounting base 1 can be installed on the ceiling to function as a ceiling light. It can also be installed on the wall to function as a wall light. It can be attached to the ceiling or wall using screws. The mounting base 1 features a flexible, conductive contact terminal 3, which is connected to the mains power supply.

[0023] Optionally, the elastic conductive contact terminal 3 comprises an L-shaped connecting plate 31 and a terminal body 32, which are connected to each other. The terminal body 32 comprises a first clamping plate 321 and a second clamping plate 322, which are arranged opposite each other. In detail, the first clamping plate 321 is curved and comprises, in sequence, a first angled projecting section 3211, a first contact section 3212, a first inclined section 3213, and a first connecting section 3214. The second clamping plate 322 is curved and comprises, in sequence, a second angled projecting section 3221, a second contact section 3222, a second inclined section 3223, and a second connecting section 3224.The first angled projecting section 3211 and the second angled projecting section 3221 project outwards at an angle, facing away from each other, thus forming a V-shaped guide opening. The first contact section 3212 and the second contact section 3222 are opposite each other to form a clamping section. The first inclined section 3213 and the second inclined section 3223 are inclined away from each other, thus forming a V-shaped clamping opening. The first connecting section 3214 and the second connecting section 3224 are opposite each other and are each connected to the L-shaped connecting plate 31. The first connecting section 3214 is arranged parallel to the second connecting section 3224.

[0024] Specifically, a plug 4 and a spring plate 5 are provided on the mounting base 1. A confined space, open on one side, is formed between the plug 4 and the L-shaped connecting plate 31. The plug 4 has a wire groove 41, which is connected to a first edge of the L-shaped connecting plate 31. The wire groove 41 serves to insert a mains connection wire. The spring plate 5 is U-shaped and comprises a base plate 51, a first side plate 52, and a second side plate 53, which are located on two sides of the base plate 51. The second side plate 53 is in contact with and connected to a second edge of the L-shaped connecting plate 31. The first side plate 52 rests elastically against the plug 4. A clamping space for clamping a conductor wire is formed between the first side plate 52 and the first edge of the L-shaped connecting plate 31.The first side plate 52 is inclined and forms an acute angle with the base plate 51, giving the first side plate 52 a good elastic clamping effect. The mains connection wire is inserted via the wire groove 41 and clamped by the elasticity of the first side plate 52 between the first side plate 52 and the first edge of the L-shaped connecting plate 31, thus enabling quick assembly of the mains connection wire. After connecting the mains connection wire to the spring plate 5, an electrical connection is made between the spring plate 5 and the elastic conductive contact terminal 3.

[0025] Furthermore, it is provided that a mounting base 11 is formed on the mounting base 1, in which the plug 4, the spring plate 5, and the elastic conductive contact terminal 3 are arranged sequentially from the inside out. Two opposing mounting bases 1 are provided. In each of the mounting bases 1, the plug 4, the spring plate 5, and the elastic conductive contact terminal 3 are arranged sequentially from the inside out, with the elastic conductive contact terminal 3 in the mounting base 1 being connected to the neutral conductor and the phase conductor of the power supply, respectively.

[0026] The luminaire body 2 is rotatably and detachably connected to the mounting base 1. A light-emitting element 6 is provided on the luminaire body 2. A conductive contact plate 7 is also provided on the luminaire body 2. One end of the conductive contact plate 7 is connected to the light-emitting element 6, and the other end of the conductive contact plate 7 can be clamped by the elastic conductive contact terminal 3 when the luminaire body 2 is rotated. The conductive contact plate 7 connects the power supply to the light-emitting element 6. The light-emitting element 6 can be an LED light source panel with a DOB design, divided into three smaller circuit boards. The LED light source panel is fixed to the luminaire body 2 by hot melting.

[0027] Optionally, the luminaire body 2 and the mounting base 1 are rotatably and detachably connected to each other by the position-limiting interaction of a limiting rib and a limiting groove. Specifically, a first limiting rib 12 is provided on the mounting base 1 in the circumferential direction. A limiting sliding groove 13 is formed between the first limiting rib 12 and the mounting base 1. A tail end of the first limiting rib 12 is positioned adjacent to the elastic conductive contact terminal 3. A head end of the first limiting rib 12 is provided with an inclined guide surface 121. A second limiting rib 21 is provided on the luminaire body 2 in the circumferential direction, which can slide into the limiting sliding groove 13. A sliding end of the second limiting rib 21 is positioned adjacent to the conductive contact plate 7.When the second limiting rib 21 slides into the limiting sliding groove 13, the conductive contact plate 7 slides into the elastic conductive contact clamp 3.

[0028] By rotating the luminaire body 2, the second limiting rib 21 slides along the inclined guide surface 121 at the head end of the first limiting rib 12 into the limiting sliding groove 13. This guides the conductive contact plate 7 slidably between the first clamping plate 321 and the second clamping plate 322 of the elastic conductive contact terminal 3. Specifically, the conductive contact plate 7 slides between the first contact section 3212 and the second contact section 3222, thus closing the circuit. In this position, the second limiting rib 21 and the first limiting rib 12 are aligned and lock into place. When the luminaire body 2 is rotated in the opposite direction, the conductive contact plate 7 slides out of the elastic conductive contact terminal 3.Simultaneously, the second limiting rib 21 slides out of the first limiting rib 12, allowing the luminaire body 2 to be removed for replacement. To ensure more stable mounting, the first limiting rib 12 and the second limiting rib 21 are each designed as two opposing ribs, with the first limiting rib 12 and the second limiting rib 21 being uniquely assigned to each other.

[0029] Furthermore, it is provided that a first mounting ring 14 is formed on the mounting base 1 in the axial direction, on which the first limiting rib 12 is formed in the radial direction. A second mounting ring 22 is formed on the luminaire body 2 in the axial direction, on which the second limiting rib 21 is formed in the radial direction. The width dimension of the second limiting rib 21 is matched to the limiting sliding groove 13 in order to allow the second limiting rib 21 to slide into the limiting sliding groove 13 and at the same time prevent wobbling of the luminaire body 2 relative to the mounting base 1.

[0030] Optionally, the conductive contact plate 7 is L-shaped. One edge of the L-shaped conductive contact plate 7 interacts with the elastic conductive contact clamp 3, and the other edge of the L-shaped conductive contact plate 7 extends through the luminaire body 2 and is connected to the light-emitting element 6. Specifically, a pressure cover 8 is provided on the luminaire body 2, which covers one edge of the L-shaped conductive contact plate 7 to restrict its movement.

[0031] In the luminaire according to the embodiment of the present utility model, the luminaire body 2 is rotatably and detachably connected to the mounting base 1, which eliminates the need to disconnect or connect power cables and thus simplifies disassembly and assembly. Simultaneously, an elastic conductive contact terminal 3 is provided on the mounting base 1, and a conductive contact plate 7 is also provided on the luminaire body 2. When the luminaire body 2 is rotated, the conductive contact plate 7 can be clamped by the elastic conductive contact terminal 3, ensuring a stable electrical connection between the conductive contact plate 7 of the luminaire body 2 and the elastic conductive contact terminal 3 of the mounting base 1 and preventing poor contact.
