Description

Technical Field

[0001] This utility model relates to a lamp holder connection structure and a lighting device including the lamp holder connection structure. Background Technology

[0002] Modern life is replete with various types of lighting fixtures, including table lamps and floor lamps, which have a straight support and illuminate the work surface downwards. In related technologies, these fixtures typically include a lamp holder, a lamp post, and a lamp head. The lamp head contains a light-emitting element that emits light downwards onto the work surface. Due to different placement of the fixtures and varying user habits, the illumination position of the lamp head sometimes needs to be adjusted. Therefore, it is desirable for the lamp head to be rotatable to adapt to different lighting needs. Of course, when providing a rotatable lamp head connection structure, we also want to ensure reliable connection and stable positioning of the lamp head without affecting the overall appearance of the fixture.

[0026] The lamp holder connection structure and lighting device proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The structure of the lighting device in a preferred embodiment of this application is as follows: Figure 11 As shown, the lighting device is a floor lamp, including a lamp head 2, a base 5, a vertical pole 4, and a horizontal bar 3. One end of the vertical pole 4 is connected to the base 5, and the other end is connected to the horizontal bar 3. The horizontal bar 3 serves as a support and is connected to the lamp head 2. The lamp head 2 contains a light source (not shown) that emits light towards the base 5. The light-emitting surface of the lamp head 2 is rectangular, and its light spot is also rectangular, which can evenly illuminate the work area below it. Due to the limitations of the floor lamp's placement, in some cases its light spot cannot perfectly match the tabletop below. Therefore, the lamp head 2 needs to be rotated a certain angle along the axis perpendicular to the ground so that the light spot can cover the entire tabletop, achieving uniform illumination of the entire tabletop. Thus, the lamp head 2 and the horizontal bar 3, which serves as a support, need to be connected through the rotatable lamp head connection structure 1 provided in this application.

[0028] Example 1: Lamp holder connection structure Figure 1 , Figure 2 , Figure 3 As shown, the assembly includes a base 11, a connector 15, and a rotating connection 12. The base 11 is connected to the lamp holder 2, and the rotating connection 12 is used to connect a support member to achieve the installation of the lamp holder 2. The base 11 and the rotating connection 12 are connected by the connector 15. After assembly, the rotating connection 12 can be pivotally connected to the base 11 with the connector 15 as the pivot.

[0029] In this embodiment, the base 11 is as follows Figure 5 The image shows a disc that can be fixed to the lamp head 1 with screws. The connector 15 is perpendicular to the base 11 and also perpendicular to the light-emitting surface of the lamp head 1, allowing the lamp head 1 to be rotated to adjust the lower illumination area. In other preferred embodiments, the base 11 may also be the outer shell of the lamp head 1, which is not limited in this application.

[0030] To secure the connector 15, a second through hole 1101 is provided on the base 11, through which the connector 15 passes. The connector 15, acting as the pivot of the rotating connection part 12, needs to be fixedly connected to the base 11, with no relative rotation between them. Therefore, a circumferential limiting structure is provided between the connector 15 and the base 11. A first limiting structure is provided on the connector 15, and a second limiting structure, cooperating with the first limiting structure, is provided in the second through hole 1101 to restrict the connector 15 from rotating within the second through hole 1101. Specifically, the connector 15 is as follows... Figure 6 As shown, a bolt 1501 passes through the base 11 and the rotating connection 12 in sequence, and then engages with a nut 16, which serves as a fastener, to connect the base 11 and the rotating connection 12. The axial cross-section of the bolt 1501 is oblong, with two threadless limiting surfaces 1502 serving as the first limiting structure. The second through hole 1101 on the base 11 is a matching oblong hole, which serves as the second limiting structure. In other preferred embodiments, the limiting structure can also be a combination of a protrusion and a slot. Furthermore, the connector 15 can be directly fixed to the base 11, or it can be an integral structure with the base 11, in which case the limiting structure is not required. The bolt 1501 is a hollow structure with a wire-passing hole 1503 in the middle. The wire can enter the lamp holder 1 through the wire-passing hole 1503 to achieve electrical connection.

[0031] The rotating connection part 12 includes a rotating plate 13 and a connecting joint 14 disposed on the rotating plate. For example... Figure 4 As shown, a first through hole 1301 is provided in the middle of the rotating plate 13. When connected to the base 11, the connector 15 passes through the second through hole 1101 on the base 11 and the first through hole 1301 on the rotating plate 13. The nut 16 is threadedly connected to the connector 15 on the outer side of the rotating plate 13 away from the base 11. The first through hole 1301 is a round hole with a diameter slightly larger than the thread outer diameter of the bolt 1501, so that the rotating plate 13 can rotate relative to the base 11 with the connector 15 as the axis of rotation. To prevent the nut 16, which is a fastener, from loosening, an elastic washer 18 is provided between the rotating plate 13 and the nut 16. The rotating plate 13 and the nut 16 abut against the opposite sides of the elastic washer 18, respectively.

[0032] The connecting joint 14 includes a first pipe section 1401 and a second pipe section 1402 that are nested together. One end of the first pipe section 1401 is connected to the rotating plate 13, and the other end is connected to the second pipe section 1402. The first pipe section 1401 is as follows... Figure 8 As shown, a hollow sleeve has locking sheet metal holes 14012 on the inner sides of its four corners. A rotating plate 13 has screw holes 1303, and the rotating plate 13 and the first pipe section 1401 are connected by screws 1901. A first connecting hole 14011 is also provided on the side wall of the first pipe section 1401. Correspondingly, a second connecting hole 14022 is also provided on the side of the second pipe section 1402, as shown... Figure 9 As shown. During connection, at least one end of the second pipe segment 1402 is inserted into the first pipe segment 1401, the first connecting hole 14011 and the second connecting hole 14022 are aligned, and the screw 1902 is inserted to achieve connection. The other end of the second pipe segment 1402 is connected to the crossbar 3, which serves as a support member.

[0033] The connector 14 is divided into two parts, which makes the lamp holder connection structure 1 easy to assemble. The assembly process is as follows: Figure 10 As shown. First, bolt 1503 is placed into base 11, and the first pipe section 1401 and rotating plate 13 are connected and fixed. The assembled first pipe section 1401 and rotating plate 13 are placed onto bolt 1503, and then elastic washer 18 is placed onto bolt 1503, and nut 16 is tightened. Then, second pipe section 1402 is inserted into first pipe section 1401 and connected with screw 1902. In this embodiment, second pipe section 1402 is as follows: Figure 9 As shown, a connecting screw hole 14021 is also provided on it for connection with the support component. In other preferred embodiments, the second pipe section 14021 can be part of the lamp post, which is not limited in this application. The bolt 1501 has a hollow structure and a wire through hole 1503 is provided in the middle. The wire can pass through the wire through hole 1503 from the lamp post into the lamp holder 1 to achieve electrical connection.

[0034] The lamp head connection structure 1 allows the lamp head 2 to rotate relative to its mounting support, but for the matching of the light spot between the lamp head 2 and the working surface, a 360-degree rotation of the lamp head 2 is not required. Therefore, the lamp head connection structure 1 provided in this application also includes a limiting structure to restrict the rotation angle of the lamp head 2. Specifically, the limiting structure consists of a limiting protrusion 1302 on the rotating plate 13 facing the base 11, and an abutment structure with the limiting protrusion 1302. The abutment structure can be a limiting block, a groove, or other structure provided on the base 11. In this embodiment, no abutment structure is provided on the base; instead, the limiting function is achieved through a non-circular limiting pad 17. As shown in the figure, the limiting pad 17 includes a third through hole 1701, which has the same shape as the second through hole 1101 on the base 11, also being an oblong hole. This ensures that the limiting pad 17 will not rotate relative to the connector 15. The outer periphery of the limiting shim 17 includes two interconnected arc segments, namely a limiting segment 1704 and a clearance segment 1702. The diameter of the limiting segment 1704 is larger than the diameter of the clearance segment 1702, and the connection between the limiting segment 1704 and the clearance segment 1702 forms a limiting surface 1703. When the rotating plate 13 rotates, it is limited by the cooperation of the limiting protrusion 1302 and the limiting surface 1703. By using the limiting shim 17 for limiting, different shapes of limiting shims 17 can be selected according to different needs, making the setting of the rotation angle of the lamp head 2 more flexible.
