[0002] With the development of LED lighting technology, LED lamps have been used in trade, office, business and other occasions. They are high in brightness, even in light, beautiful, energy-saving and environmentally friendly. While LED lamps are widely praised, their important component - the driving power supply, has also been paid attention to. The quality of the driving power supply of LED lamps directly restricts the reliability of LED lamps. The driving power supply of LED lamps is a power converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Usually: the input of the LED driving power supply includes high-voltage industrial frequency AC (i.e., mains), low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of an electronic transformer), etc., and the output of the LED driving power supply is mostly a constant current source that can change the voltage as the forward voltage drop value of the LED changes. At present, when the LED power supply driver is damaged, the lampshade needs to be removed to repair or replace the LED power supply driver in the lampshade. Improper operation will damage the entire LED lamp and the operation is troublesome. Utility Model Content

When the second fixed shell 206 and the first fixed shell 205 rotate, the multiple conductive components 209 on the insulating plate 208 rotate accordingly, so that the conductive components 209 extend out of the connecting groove 203, and at the same time the guide rod 210 rotates along the guide groove 207, and the conductive components 209 are connected to the guide rail 3 when extended.

[0036] like Figure 4 As shown, in some embodiments of the utility model, in order to achieve the effect of the electrically connected guide rail 3, the second power-carrying part 300 includes a rotating rod 301 movably mounted on another of the mounting grooves 201, and a fixed rod 302 is fixedly inserted in the rotating rod 301, and a first conductive copper sheet 303 is provided on the fixed rod 302, a part of the first conductive copper sheet 303 is arranged in one of the connecting grooves 203, and the upper end of the first conductive copper sheet 303 is connected to the circuit board 6.

[0037] When a four-wire guide rail power supply device using the above structure is in operation, the user drives the adjustment driving mechanism 400 to make the rotating rod 301 rotate in the sleeve groove 201. When the sleeve groove 201 rotates, the fixed rod 302 is driven to rotate, so that the protruding part under the first conductive copper sheet 303 extends out of the connecting groove 203, and the first conductive copper sheet 303 is connected to the line on the guide rail 3.

[0038] like Figures 1 to 6 As shown, in some embodiments of the utility model, in order to drive the first power supply part 200 and the second power supply part 300 to extend and adjust and select the required lines, the adjustment drive mechanism 400 includes a handle 401 fixed to the upper end of the fixed rod 302 and the upper end of the second fixed shell 206, and a clearance groove 402 is provided on the left and right sides of the whole shell 4, and each of the handles 401 is arranged in an adjacent clearance groove 402, and a rotating wheel 403 is movably sleeved in the sleeve groove 201, and a rotating plate is movably sleeved above the first fixed shell 205 and the second fixed shell 206. 404, an empty slot 405 is provided on the rear side of the rotating plate 404, an annular conductive copper sheet 406 is movably inserted on the rotating plate 404, a plurality of protrusions 407 are provided on the annular conductive copper sheet 406 at intervals, a blocking rod 408 is symmetrically fixed on the rear side of the rotating plate 404, the rear side of the annular conductive copper sheet 406 is blocked on the blocking rod 408, the blocking rod 408 is inserted on the rotating wheel 403, a boss 409 is fixed in the middle of the rotating wheel 403, and corresponding marks 410 are provided on the boss 409 and the periphery of the rotating wheel 403.

[0039] The conductive component 209 includes a plurality of second conductive copper sheets 2091 fixed on the left and right sides of the insulating plate 208, a first conductive sheet 2092 and a second conductive sheet 2093 are symmetrically connected on the left side of the circuit board 6, a connecting copper sheet 2094 is fixed in the empty slot 405, the first conductive sheet 2092 is connected to the protrusion 407, and the second conductive sheet 2093 is connected to the second conductive copper sheet 2091.

[0040] When a four-wire guide rail power supply device using the above structure is in operation, when the user needs to extend the conductive component 209, the user swings each handle 401, so that each handle 401 drives the fixing rod 302 and the second fixing shell 206 to rotate, so that the conductive component 209 and the first conductive copper sheet 303 extend out of the connecting groove 203. When the required conductive component 209 needs to be adjusted to be connected to the corresponding line of the guide rail 3, the user rotates the rotating wheel 403 set in the sleeve groove 201. When rotating, the user can rotate to a suitable gear according to the corresponding mark 410 on the boss 409 and the rotating wheel 403. When the rotating wheel 403 rotates, the rotating plate 404 is driven to rotate through the blocking rod 408, so that the annular conductive copper sheet 406 blocked by the blocking rod 408 on the rotating plate 404 rotates accordingly, and at the same time, the rotating plate 404 drives the connecting copper sheet 2094 fixed in the empty slot 405 to rotate, and the connecting copper sheet 2094 and the annular conductive copper sheet 406 are always connected. During the rotation, one of the protrusions 407 provided at intervals on the annular conductive copper sheet 406 will be buckled at the convex point at the upper end of the first conductive sheet 2092, and the second conductive sheet 2092 is connected to one of the second conductive copper sheets 2091 provided on the rear side (the second conductive copper sheet 2091 is at Figure 6 As can be seen in the figure, there are two groups on the left and right sides, each group is facing the front and the rear respectively), and the connecting copper sheet 2094 is connected to one of the second conductive copper sheets 2091 set to the front side. It can be seen that when the user rotates the rotating wheel 403 to different gears, different second conductive copper sheets 2091 can be connected to the circuit board 6, thereby achieving the connection between the second conductive copper sheet 2091 and different lines on the guide rail 3.

[0041] like Figure 1 , 3As shown in Figure 5, in some embodiments of the utility model, a cover shell 21 corresponding to the left side of the first shell 1 is installed and fixed on the left side of the second shell 2, a limit block 22 is provided on the front side of the first shell 1, and a snap-fit ​​block 23 is provided on the first shell 1 and the second shell 2.

After the first shell 1 and the second shell 2 are inserted into the guide rail 3, the snap-fit ​​block 23 is snapped into the guide rail 3 to prevent the first shell 1 and the second shell 2 from falling. At the same time, the limit block 22 is used to balance the positions of the first shell 1 and the second shell 2 inserted into the guide rail 3.

Figure 5 In some of the embodiments shown, there is only a second conductive copper sheet 2091 for connection, so the copper wire on the guide rail 3 can eliminate the middle copper strip 32 (i.e., D+ and D-) as needed, and the user can adjust the color temperature of the lamp body when pulling the color temperature adjustment button 24 to move in the adjustment hole 25.
