Please refer to the second, third and fifth figures. To use the combined magnetic track light, first insert the inserts 42 of the connecting piece 4 into the inserts on the adjacent base 21 respectively. Slot 24, so that the first metal elastic piece 43 is electrically connected to the second conductor 252, and the rails 22 of the adjacent lamp holders 2 are connected to each other, so that the base 21 of the adjacent lamp holder 2 Set up vertically.

Then the closed side 212 of the base 21 is combined with a ceiling (not shown), for example, it can be locked to the ceiling by a screw (not shown), or the closed side 212 is combined with The present invention is not limited to an existing guide rail on the ceiling, and the scene is not drawn in the drawings.

After the base 21 is combined with the ceiling, the power supply portion 11 of the power supply unit 1 is inserted into the recess 24 of one of the bases 21, so that the second metal spring 111 on the power supply portion 11 is electrically connected to the rail 22 of the second conductor 252.

Then, the base end 32 of the lighting unit 3 is set on the rail 22 from the open side 211 of the base 21. When the base end 32 of the lighting unit 3 approaches the rail 22, the second magnetic attraction portion 321 on the lighting unit 3 and the first magnetic attraction portion 23 of the lamp holder 2 attract each other, and The lighting unit 3 is drawn close to the base 21 to contact the rail 22.

When the base end 32 of the lighting unit 3 contacts the rail 22, the electrical contact 322 of the base end 32 will also contact the first conductor 251 on the rail 22, so that the light source end 31 passes through The electrical contact 322 of the base end 32 is electrically connected to the first conductor 251.

Finally, the power supply unit 1 is turned on, and when the lighting unit 3 is positioned on the base 21 combined with the power supply unit 11, the electric energy sent by the power supply unit 1 sequentially passes through the second metal shrapnel 111 and the The second conductor 252 and the first conductor 251 on the track 22, and pass through the lighting unit 3 The electrical contact 322 makes the light source end 31 light up. Or, when the lighting unit 3 is located on the base 21 that is not combined with the power supply unit 11, the electrical energy sent by the power supply unit 1 passes through the second metal spring 111 and the second metal spring 111 and the rail 22 in this order. The second conductor 252, the first conductor 251, reach the second conductor 252 on the base 21 where the lighting unit 3 is located via the first metal spring 43 and the third conductor 44 of the connector 4, and finally Similarly, the first conductor 251 is electrically connected through the electrical contact 322 of the lighting unit 3 to make the light source end 31 light up.

Since both the first conductor 251 and the first magnetic attraction portion 23 extend along the length direction, when proper force is applied without separating the lighting unit 3 from the first conductor 251, the lighting unit 3 It can move on the rail 22 along the length direction. At the same time, by the first magnetic attraction portion 23 and the second magnetic attraction portion 321 of the lighting unit 3 attracting each other, even if the lighting unit 3 moves on the track 22, the lighting unit 3 can still be attracted On the track 22 without falling.
