As shown in fig. 13A, when the pair of sliding members 223 are relatively stationary in the width direction of the mounting body 210 by the second elastic member 226 and the pressing member 221, and the relative distance between the pair of sliding members 223 is the farthest, the coupling device 200 is mounted to the guide rail 100, and at this time, the first connection member 1211 is magnetically attracted to the second connection member 212.
As shown in fig. 13B, when the switch portion 2222 of the locking element 222 is moved in the width direction of the mounting body 210 toward the side away from the pressing element 221 by an external force, one end of the locking portion 2221 of the locking element 222 moves out of the card slot 2214 of the pressing element 221, and at the same time, the pressing element 221 moves in the height direction of the mounting body 210 toward the side away from the fixing element 230, that is, one end of the locking portion 2221 of the locking element 222 slides relatively into the groove 2213 of the pressing element 221, and relative sliding movement occurs between the transmission portion 2211 of the pressing element 221 and the pair of sliding elements 223, so that the relative distance between the pair of sliding elements 223 gradually decreases.
As shown in fig. 13C, further, the elements in the coupling device 200 return to the initial position, that is, the pressing element 221 is relatively stationary in the height direction of the mounting body 210 under the action of the first elastic element 225 and a bottom surface of the mounting body 210 corresponding to the pressing element 221; the pair of sliding members 223 are relatively stationary in the width direction of the mounting body 210 by the second elastic member 226 and the pressing member 221, and the relative distance between the pair of sliding members 223 is the closest; the locking member 222 is relatively stationary in the height direction of the mounting body 210 by a bottom surface of the sliding member 223 and the mounting body 210 corresponding to the locking member 222, the locking member 222 is relatively stationary in the width direction of the mounting body 210 by an inner wall of the pressing member 221 and the mounting body 210 corresponding to the locking member 222, and one end of the locking portion 2221 of the locking member 222 is located in the groove 2213 of the pressing member 221.

It will be understood by those skilled in the art that the detachment of the coupling device 200 from the guide rail 100 can be easily derived from the above steps, and the present invention will not be described in detail.
As will be understood by those skilled in the art, when the lighting device 10 is mounted on the guide rail 100, the first clamping portion 2233 is clamped with the second clamping portion 123, and the second clamping portion 123 is located between the first clamping portion 2233 and the sliding body 2231. By engaging the first engaging portion 2233 with the second engaging portion 123, the problem that the lighting device 10 falls off from the rail 100 due to the decrease of the magnetic force between the second connecting element 212 and the first connecting element 1211 with the increase of time and the number of times of detachment can be further prevented, and the stability of the lighting system 1 can be improved.
In the present invention, the second conductive element 1221 is connected in contact with the first conductive element 224. Preferably, the first conductive element 224 is a metal sheet, such as: a copper sheet; the second conductive element 1221 is an elastic metal strip, for example: and (4) a copper strip.

The middle portion of the first conductive element 224 protrudes out of the inner wall of the connecting body 2232 to be better connected with the second conductive element 1221, so that the conducting current can realize the electrical connection between the lighting device 10 and the track 100. It will be appreciated by those skilled in the art that the first conductive element can be replaced to further prevent the problem of poor wire contact between the first conductive element 224 and the second conductive element 1221.
In the present invention, at least one of the first connection element 1211 and the second connection element 212 is a magnetic element. When only one of the first connection element 1211 and the second connection element 212 is a magnetic element, the other can be attracted by the magnetic element, for example: when the first connection element 1211 is a magnetic element, the second connection element 212 can be attracted by the first connection element 1211, in which case the material of the second connection element 212 includes at least one of iron, cobalt, and nickel that can be attracted magnetically; similarly, when the second connection element 212 is a magnetic element, the first connection element 1211 can be attracted by the second connection element 212, in which case the material of the first connection element 1211 includes at least one of iron, cobalt, and nickel, which can be attracted magnetically. When the first connection element 1211 and the second connection element 212 are both magnetic elements, the magnetic poles of the connection positions of the first connection element 1211 and the second connection element 212 are opposite. It will be appreciated by those skilled in the art that the two magnets may only attract when the poles are opposite. Preferably, the first connection element 1211 is an iron plate, and the second connection element 212 is a magnet piece.
In the present invention, the first connection element 1211 and the second connection element 212 are detachably connected, so that the magnetic force between the second connection element 212 and the first connection element 1211 can be adjusted by replacement, the problem that the magnetic force between the second connection element 212 and the first connection element 1211 is gradually weakened with the increase of time and the number of times of detachment, so as to cause the illumination device 10 to fall off from the guide rail 100 is prevented, and the stability of the illumination system 1 is improved. It should be noted that the magnetic connection between the first connection element 1211 and the second connection element 212 is required to satisfy that the magnitude of the magnetic force generated between the first connection element 1211 and the second connection element 212 is larger than the magnitude of the gravity of the illumination device 10 itself.
