The above parts are the same as the existing controller, the power module 101 supplies power to the processor 102 and the control module 103, and the control module 103 may generate or process a first control signal, which is connected to an external control bus through the first communication interface 106, so as to control the controlled device. The luminaire control will generally follow a certain protocol, and the lighting system controller 1 of the embodiment of the utility model is applied to a track lighting system, and thus employs a wired protocol. In this embodiment, the first control signal is a DALI control signal, the control module 103 is a DALI host, the outside of the first communication interface 106 is connected to a DALI bus, and the lighting system controller 1 controls a DALI lamp connected to the bus.

When a user purchases a DALI lamp, the existing lighting control system is PWM controlled or 0-10V controlled, the DALI lamp cannot be integrated into the existing system and controlled uniformly.

If the second communication interface 105 receives the third control signal, the processor 102 receives the signal obtained by converting the third control signal by the parsing circuit 108, and converts the signal into the first control signal by the processor 102, and then transmits the first control signal to the control module 103. When the second communication interface 105 has the second control signal or the third control signal input, the control module 103 transmits the first control signal transmitted from the processor 102 to the first communication interface 106.

A lighting system as recited in claim 12, further comprising an upper level rail, said upper level rail comprising a fourth conductive strip for transmitting a second control signal or a third control signal, said fourth conductive strip being electrically connected to said second conductive strip.

14. A lighting system as recited in claim 13, wherein said second control signal is a PWM control signal, said third control signal is a 0-10V control signal, said first control signal is a DALI control signal, and when said second control signal or said third control signal is present on said fourth conductive strip, said lighting system controller converts said second control signal or said third control signal into said first control signal to control said lighting unit, otherwise said lighting system controller directly generates a first control signal to control said lighting unit.
