[0039] Therefore, the lamp controller can independently control each channel, and the user can accurately control the on-off state of each lamp according to the actual demand; whether it is the partition lighting control in large commercial space or the local lighting adjustment on the industrial production line, it can realize fine management.

[0040] As a further optimization of the embodiment, as shown in Figure 3 The control circuit of each control unit comprises a triode Q1, a triode Q2, a resistor R1, a resistor R2, a resistor R3, a resistor R4 and a diode D1. Figure 3Only show a way control circuit, a lamp control has 16 ways control circuit, each way control circuit circuit structure with Figure 3 The structure shown is the same; wherein, the triode Q1 adopts the PNPTriode of model SS8550, the triode Q2 adopts the NPTriode of model S8050;

[0041] The emitter of the triode Q1 is connected to the power supply, the base of the triode Q1 is electrically connected with the first end of resistor R1 and the first end of resistor R2 respectively, the second end of resistor R1 is used as the controlled end of the control circuit, and the second end of the resistor R1 is electrically connected with the IO port of the host controller;

[0042] The collector of the triode Q1 is electrically connected with the first end of resistor R3 and the first end of resistor R4 respectively, and the second end of the resistor R4 is electrically connected with the base of the triode Q2.

[0043] The emitter of the triode Q2 is electrically connected with the positive electrode of the diode and the first end of the coil of the relay K1 respectively, and the second end of the coil of the relay K1 and the negative electrode of the diode D1 are both connected to the power supply.

[0044] The second end of the resistor R2, the second end of the resistor R3 and the collector of the triode Q2 are all grounded.

[0045] In this embodiment, the IO port of the host controller outputs high level, so that the base of the triode Q1 is high level, then the triode Q1 is turned on, the base of the triode Q2 is high level, and then the triode Q2 is turned on, after the triode Q2 is turned on, the coil of the relay K1 is connected to the power supply, the switch contact of the relay K1 is attracted, the power supply circuit of the lighting lamp is connected to the power supply, and the lighting lamp is turned on; when the IO port of the host controller outputs low level, the triode Q1 and the triode Q2 are both in the cut-off state, the coil of the relay K1 is disconnected from the power supply, the switch contact of the relay K1 is separated, the power supply circuit of the lighting lamp is in the cut-off state, and the lighting lamp is turned off.
