Referring to the four-wire guide rail lamp provided in the embodiment shown in fig. 9, four conductive strips 12 are arranged on the side wall of the chute 11, three of which are live wires, one of which is zero wire, and three paths of electricity are provided, four connecting terminals 30 are correspondingly arranged in each group of lamp body, and are respectively a first connecting terminal 31, a second connecting terminal 32, a third connecting terminal 33 and a fourth connecting terminal 34. When the lamp is installed, one end of the first wiring terminal 31 of each lamp body is contacted with a zero line, and one end of the other wiring terminals are respectively contacted with three live lines.

The second conductive member 52 may be movably disposed in a manner of rotating, for example, a single set of lamp bodies, where the first conductive member 51 contacts the first connection terminal 31, and the second conductive member 52 contacts the second connection terminal 32, the third connection terminal 33 or the fourth connection terminal 34, so that the driving power is conducted with the corresponding fire wire, and when the set of lamp bodies needs to be turned on, only the mains supply needs to be input to the corresponding fire wire. Referring to the embodiment shown in fig. 6-11, the track light also includes a drive member 60 that drives the second conductive member 52, such as to rotate the second conductive member 52.

During assembly, the driving handle 85 drives the rotating piece to rotate, so that the wiring terminal extends out of the sliding block to enter the sliding groove 11 and is contacted with the conducting strip, and then the connection between the lamp body and the sliding rail is completed.
