The invention provides a lighting control device. The lighting control device comprises a power conversion module, a controllable switch module, a control module and a signal module. The signal moduleis used for sending a first control signal and a second control signal, so that the controllable switch module generates a first power supply signal under the control of the first control signal, andthe control module cuts off the circuit connection between a power supply module and lighting equipment under the joint control of the second control signal and the first power supply signal; or, thesignal module is used for sending a third control signal and a fourth control signal, so that the controllable switch module generates a second power supply signal under the control of the third control signal and the control module establishes circuit connection between the power supply module and the lighting equipment under the joint control of the fourth control signal and the second power supply signal. In the invention, when the device is in a non-working state, the controllable switch module does not consume electric energy, so that the control module is in a non-working state, and theelectric energy consumption when the device is in a non-working state is reduced.
