The lamp provided by the embodiment of the application is suitable for being mounted on a track 10, the track 10 is fixedly mounted on a fixed mounting surface, and the fixed mounting surface can be a house concrete ceiling, a suspended ceiling, a wall surface, and the like. The lamp is also commonly called a track lamp and is generally used as a spot lamp in places needing important illumination.

As shown in fig. 1 and 2, the lamp comprises a driving device 20 and a lamp cap assembly 30, wherein the driving device 20 is suitable for being slidably mounted on a track 10, the driving device 20 is electrically connected with a conductive rail 11 of the track 10, the lamp cap assembly 30 is mounted on the driving device 20, and the lamp cap assembly 30 is electrically connected with a circuit board of the driving device 20. As shown in fig. 2 to 4, the driving device 20 includes a housing 21, a rotating shaft 22, a supporting member 24 and two elastic conductive plates 23, the rotating shaft 22 is rotatably mounted in the housing 21, the rotating shaft 22 is provided with a through hole 221, each conductive plate 23 includes a first section 231 and a second section 232 which are integrally formed and connected with each other, the first section 231 is inserted into the through hole 221, an end of the first section 231 is electrically connected with the circuit board, the second section 232 is bent and arranged relative to the first section 231, an end of the second section 232 penetrates out of the housing 21, the second section 232 is electrically connected with the conductive rail 11, the supporting member 24 is axially and limitedly inserted into the through hole 221, the two conductive plates 23 are symmetrically arranged relative to the supporting member 24, and the supporting member 24 and a wall of the through hole 221 clamp and fix the first section 231 so that the second section 232 rotates synchronously with the rotating shaft 22.

The rotating shaft 22 of the driving device 20 of the lamp of the present application is provided with a through hole 221, two conductive sheets 23 are mounted by inserting, and the first section 231 of the two conductive sheets 23 is pressed and fixed on the wall of the through hole 221 by inserting the support 24 into the through hole 221. The second section 232 of the conductive piece 23 penetrates the housing 21 and can rotate synchronously with the rotating shaft 22, so that when the driving device 20 is placed on the track 10 and the rotating shaft 22 is rotated, the second section 232 of the conductive piece 23 rotates along with the second section 232 to be electrically connected with the conductive rail 11 of the track 10. The rotating shaft 22, the conductive sheet 23 and the supporting piece 24 of the lamp are assembled in a sequential inserting mode, and compared with the existing rotating shaft structure of the lamp, the assembling mode of locking two semicircular shells through a plurality of screws is higher in assembling efficiency, and the assembling production efficiency of the lamp is improved.

As shown in fig. 2, the cap assembly 30 is composed of an LED cap 31 and a connection rod 32. The first end of the connecting rod 32 is movably coupled to the housing 21, and the led lamp cap 31 is movably coupled to the second end of the connecting rod 32. In this way, the irradiation angle of the LED lamp cap 31 can be arbitrarily adjusted, and thus the irradiation angle of the LED lamp cap 31 can be adjusted for a position where important illumination is required.

As shown in fig. 3 and 4, one end of the support member 24 is provided with a first elastic arm 241 and a second elastic arm 242 opposite to each other, the first elastic arm 241 and the second elastic arm 242 extend in the same direction, and the first elastic arm 241 and the second elastic arm 242 are disposed at intervals. After the first sections 231 of the two conductive sheets 23 are inserted into the through holes 221, the support 24 is inserted between the first sections 231 of the two conductive sheets 23, and the first elastic arms 241 and the second elastic arms 242 are compressed toward each other, the first elastic arms 241 and the second elastic arms 242 respectively press against the two first sections 231, that is: the first elastic arm 241 clamps and fixes the first section 231 of one conductive sheet 23 with the wall of the through hole 221, and the second elastic arm 242 clamps and fixes the first section 231 of the other conductive sheet 23 with the wall of the through hole 221. Further, the support 24 can be stabilized in the through hole 221 due to the elastic force generated by the first elastic arm 241 and the second elastic arm 242.

As shown in fig. 3, the other end of the supporting member 24 is provided with a third elastic arm 243 and a fourth elastic arm 244 opposite to each other, and after the supporting member 24 is inserted into the through hole 221, the third elastic arm 243 and the fourth elastic arm 244 are pressed against the wall of the through hole 221 in opposite directions, so that the elastic force generated by the third elastic arm 243 and the fourth elastic arm 244 matches the elastic force generated by the first elastic arm 241 and the second elastic arm 242, thereby more firmly stabilizing the supporting member 24 in the through hole 221. Further, as shown in fig. 3, the ends of the third elastic arm 243 and the fourth elastic arm 244 are respectively provided with a hook 245, and the first end of the rotating shaft 22 is provided with a first hooking structure 222. When the supporting member 24 is inserted into the through hole 221, the hooks 245 of the third elastic arm 243 and the fourth elastic arm 244 are hooked on the first hooking structure 222, thereby preventing the supporting member 24 from being axially separated from the through hole 221. When the hooks 245 of the third elastic arm 243 and the fourth elastic arm 244 are engaged with the two first engaging structures 222, the supporting member 24 is restricted, so that the supporting member 24 cannot rotate in the through hole 221, and the first elastic arm 241 and the second elastic arm 242 cannot deviate from the first section 231 of the conductive sheet 23 pressed by the first elastic arm and the second elastic arm 242, so that the two conductive sheets 23 are always kept stable on the wall of the through hole 221.

In the embodiment of the present application, the connecting line direction between the first elastic arm 241 and the second elastic arm 242 is perpendicular to the connecting line direction between the third elastic arm 243 and the fourth elastic arm 244. That is, the direction of the elastic force generated when the first elastic arm 241 and the second elastic arm 242 are compressed is perpendicular to the direction of the elastic force generated when the third elastic arm 243 and the fourth elastic arm 244 are compressed. In this way, after the support 24 is inserted into the through hole 221, the support 24 has four elastic force application points uniformly circumferentially to the wall of the through hole 221, so that the support 24 can be kept stable at all times without offset in the through hole 221, that is, the central axis of the support 24 is almost coincident with the hole axis of the through hole 221, so that the support 24 can be kept stably in the through hole 221.

As shown in fig. 3 and 4, the second end of the rotating shaft 22 is provided with a first notch 225 and a second notch 226 opposite to each other, and the second sections 232 of the two conductive plates 23 are respectively clamped in the first notch 225 and the second notch 226. After the two conductive plates 23 are inserted into the through holes 221, the second sections 232 of the two conductive plates 23 are respectively limited by the first notch 225 and the second notch 226, so that the two conductive plates 23 can be prevented from rotating relative to the rotating shaft 22 in the process of synchronously rotating along with the rotating shaft 22, and a fixed relative position between the two conductive plates 23 and the rotating shaft 22 can be always maintained.

As shown in fig. 1 to 4, the outer wall of the rotating shaft 22 is provided with a first fin 223 and a second fin 224, the extending direction of the first fin 223 is opposite to that of the second fin 224, and the first fin 223 and the second fin 224 penetrate out of the housing 21. When the driving device 20 is mounted on the rail 10, the rail 10 is provided with the second hooking structure 12, so that the first fin 223 and the second fin 224 are hooked on the second hooking structure 12, and the lamp cannot be separated from the rail 10 due to the gravity of the lamp. When the lamp is mounted on the track 10, the driving device 20 slides in from one end of the track 10, and the second hooking structure 12 is positioned below the first fin 223 and the second fin 224, so that the first fin 223 and the second fin 224 are blocked from falling out under the gravity action of the lamp, and then the end of the track 10 is covered by the matched end cover of the track 10 (in practice, both ends of the track 10 are covered by the matched end cover).

As shown in fig. 2 and 3, the first end of the shaft 22 is further provided with a handle 227, and an end of the handle 227 passes out of the housing 21. The handle 227 is controlled to drive the rotating shaft 22 to rotate, so that the first fin 223 and the second fin 224 are hung on the second hanging structure 12 or separated from the second hanging structure 12.

In an embodiment of the present application, the shaft 22 is an integrally formed part. Specifically, the rotating shaft 22 is an integrally injection molded plastic part, so that the manufacturing production efficiency of manufacturing the rotating shaft 22 can be improved.

As shown in fig. 3, the driving device 20 further includes a conductive wire 26, a first end of the conductive wire 26 is electrically connected to an end of the first section 231, and a second end of the conductive wire 26 is electrically connected to the circuit board. Compared with the prior art that the copper sheet is used for connecting the circuit board of the conduction driving device 20 and the conductive sheet 23, the conductive wire 26 can be flexibly deformed better, namely, the conductive wire 26 can be adaptively flexibly deformed along with the rotation of the rotating shaft 22, so that the connection conduction between the circuit board of the driving device 20 and the conductive sheet 23 is always ensured.

As shown in fig. 3 and 4, the driving device 20 further includes a power receiving screw 27 and a power receiving nut 28. The end of the first section 231 is bent and provided with a connection end 233, and the connection end 233 is provided with a through hole. The power connection screw 27 passes through the through hole and is then screwed with the power connection nut 28, the first end of the conductive wire 26 is wound around the power connection screw 27, and the power connection nut 28 and the connection end 233 clamp and fix the first end of the conductive wire 26. Thus, the conductive wire 26 is electrically connected with the conductive sheet 23 quickly and stably, and the assembly efficiency is high.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
