[0027] See also Figures 1 to 3 The embodiment of the present application provides a lamp, including a housing 10, a guide rail 20, a conductive strip 30, a driving assembly 40 and a movable lamp body 50. The guide rail 20 is installed on the housing 10, and is combined with Figure 5 The guide rail 20 has two facing slide grooves 22 and a receiving area 23 between the two slide grooves 22. Figure 4 The conductive strips 30 are arranged in pairs, and the same pair of conductive strips 30 are disposed in two chute 22, and at least a portion of the conductive strips 30 is extended along the extension direction of the guide rail 20. Figure 3 As shown, in the same pair of conductive strips 30, one conductive strip 30 is connected to the positive output terminal 40a of the driving component 40, and the other conductive strip 30 is connected to the negative output terminal 40b of the driving component 40. Figure 1 , Figure 3 The movable lamp body 50 includes a rotating shaft 51 and a light source assembly 52. ​​The light source assembly 52 can be movably mounted on the rotating shaft 51. Both ends of the rotating shaft 51 are conductive ends 51a. Figure 5 , the two conductive ends 51a are one-to-one correspondingly abutted against the same pair of conductive strips 30, and the two conductive ends 51a are electrically connected to the light source assembly 52. ​​The two conductive ends 51a are slidably connected to the two slide slots 22, respectively, and the rotating shaft 51 can rotate around the axis of the rotating shaft 51. The light source assembly 52 can be accommodated in the accommodating area 23, and the light emitting side 52a of the light source assembly 52 is arranged away from the housing 10.

[0028] Compared with the related art, the lamp provided by the present application has a housing 10 provided with a guide rail 20, a pair of conductive strips 30 are disposed in two slide grooves 22 of the guide rail 20, and the conductive strips 30 are electrically connected to the driving assembly 40. The movable lamp body 50 includes a rotating shaft 51 and a light source assembly 52, two conductive ends 51a of the rotating shaft 51 abut against the pair of conductive strips 30, and the two conductive ends 51a are connected to the light source assembly 52, so that the power of the driving assembly 40 can be transmitted to the light source assembly 52 by the conductive strips 30 and the conductive ends 51a of the rotating shaft 51. Separating the light source assembly 52 from the driving assembly 40 can reduce the possibility of the heat generated by the light source assembly 52 being transmitted to the driving assembly 40, thereby improving the reliability of the lamp. The light source assembly 52 can be movably mounted on the rotating shaft 51 to achieve position adjustment of the light-emitting side 52a of the light source assembly 52. The two conductive ends 51a of the rotating shaft 51 are slidably connected to the two slide grooves 22 so that the light source assembly 52 can move along the guide rail 20. The rotating shaft 51 can rotate around its axis to adjust the swing angle of the light source assembly 52, thereby realizing the function of the guide rail light (such as Figure 2 By adjusting the rotating shaft 51 and the light source assembly 52, the light source assembly 52 can be accommodated in the accommodation area 23 of the guide rail 20, so as to realize the panel light function (such as Figure 1 The lamp has the functions of a track lamp and a panel lamp. When the position of the movable lamp body 50 is adjusted, the electrical conductivity can be ensured so that the light source assembly 52 can emit light normally, thereby improving the user experience and having a low use cost.

[0029] Exemplarily, the guide rail 20 extends in a straight line, and the light source assembly 52 is in a rectangular parallelepiped shape. The light source assembly 52 can slide in the extension direction of the guide rail 20 through the rotating shaft 51, and the rectangular parallelepiped light source assembly 52 can be accommodated in the accommodation area 23 of the guide rail 20. When the guide rail 20 extends in a straight line, the slide 22 extends in a straight line, and the conductive strip 30 also extends in a straight line. It can be understood that the guide rail 20 can also be in other shapes, and accordingly, the light source assembly 52 should be set to a matching shape so that the light source assembly 52 can be accommodated in the accommodation area 23 of the guide rail 20. The slide 22 and the conductive strip 30 are also set to corresponding shapes.

[0030] The driving assembly 40 is used to convert the external power into the power required by the light source assembly 52 to drive the light source assembly 52 to work.

This structure is easy to form and assemble, so that the structure weight is small. Specifically, the slide rail 21 can be fixed to the housing 10 by fasteners or other mechanical connection methods. It can be understood that the guide rail 20 can also be an integrally formed structure. The inner wall of the slide groove 22 of the guide rail 20 is provided with a positioning groove 24, and the conductive strip 30 is arranged in the positioning groove 24, so that the conductive strip 30 is easy to assemble into the guide rail 20.

[0032] Exemplarily, the slide rail 21 includes a first support wall 211, a second support wall 212 and a connecting wall 213, the first support wall 211 and the second support wall 212 are spaced apart, the connecting wall 213 is connected between the first support wall 211 and the second support wall 212, and the first support wall 211, the second support wall 212 and the connecting wall 213 form a slide groove 22. When the slide rail 21 is installed on the housing 10, the first support wall 211 is arranged close to the bottom surface of the housing 10, and the second support wall 212 is used to block the rotating shaft 51 to prevent the rotating shaft 51 from falling out of the slide groove 22. The distance between the inner side of the first support wall 211 and the inner side of the second support wall 212 is slightly smaller than the outer diameter of the conductive end 51a of the shaft 51, so that when the conductive end 51a of the shaft 51 is inserted into the slide groove 22, the shaft 51 can be clamped by the first support wall 211 and the second support wall 212, and there is a certain friction between the shaft 51 and the first support wall 211 and the second support wall 212, so that the shaft 51 can be maintained at the adjusted swing angle position. The conductive bar 30 can be connected to the first support wall 211, so that when the shaft 51 slides on the slide groove 22, the conductive end 51a of the shaft 51 can reliably abut against the conductive bar 30.

When the rotating shaft 51 is assembled to the guide rail 20, the first end and the second end of the three-way pipe are respectively inserted into the two slide grooves 22 of the guide rail 20, so that the rotating shaft 51 can be swung around its axis at any position of the slide groove 22 of the guide rail 20, thereby adjusting the swing angle position of the light source assembly 52. Figure 5The third end 51c of the three-way tube is connected to the light source assembly 52, the conductive ring 511 and the light source assembly 52 are connected through a wire 54, both ends of the wire 54 are respectively connected to the conductive ring 511 and the input end of the light source assembly 52, the wire 54 can be accommodated inside the three-way tube, so that the appearance of the movable lamp body 50 is better, and the power of the driving assembly 40 is transmitted to the light source assembly 52 through the two conductive strips 30, the conductive rings 511 at both ends of the three-way tube and the wire 54 to realize power transmission.

[0034] See also Figures 3 to 5 In another embodiment of the present application, the light source assembly 52 can be rotatably mounted on the third end 51c of the three-way pipe, and the rotation axis of the light source assembly 52 relative to the three-way pipe is perpendicular to the axis formed between the first end and the second end of the three-way pipe. In this way, the rotation angle of the light source assembly 52 relative to the three-way pipe can be adjusted, and the three-way pipe can swing around its axis to achieve the swing angle adjustment of the light source assembly 52, thereby achieving the multi-directional rotation adjustment of the light source assembly 52.

[0035] See also Figure 4 In another embodiment of the present application, the light source assembly 52 is provided with a connecting piece 53, and the connecting piece 53 is threadedly connected to the third end 51c of the tee pipe, so that it is convenient to adjust the rotation angle of the light source assembly 52 relative to the tee pipe, and after adjusting the rotation angle of the light source assembly 52 relative to the tee pipe, the light source assembly 52 can be maintained at the adjusted rotation angle position.

The heat sink 521 can be made of a material with good thermal conductivity, and the heat generated by the light source board 522 is diffused to the external environment through the heat sink 521. The diffusion plate 523 is used to make the light source board 522 emit light evenly to avoid glare. The light source board 522 includes a substrate and LED lamp beads provided on the substrate. Specifically, the heat sink 521 can be a box body with an opening, the light source board 522 is installed in the box body, and the diffusion plate 523 is installed at the opening of the box body.

During assembly, damping rings are first sleeved on both ends of the rotating shaft 51, and then the rotating shaft 51 is assembled to the slide groove 22 of the guide rail 20. The damping ring is squeezed by the inner wall of the slide groove 22, so that a certain friction force is generated between the damping ring and the inner wall of the slide groove 22, so that the angular position of the rotating shaft 51 can be maintained at this position after adjusting the angular position, reducing the possibility of the rotating shaft 51 rotating due to the gravity of the light source assembly 52. ​​The damping ring can be a rubber ring to provide a certain friction force.
