The present disclosure provides a DC concentrated illumination system, including a DC distribution box configured for converting a command specification that controls the state of lamps into a voltage signal with a varying amplitude, and outputting the voltage signal via a power line; and a plurality of lamp units, each includes a lamp, a power conversion unit and a simulated load unit, wherein the power conversion unit is coupled to the lamp and the simulated load unit, and is coupled to the DC distribution box via the power line. The power conversion unit receives the voltage signal and collects the state information of the lamps when the voltage signal matches a preset convention rule successfully; and the power conversion unit controls the action of the simulated load unit to get a current signal, the DC distribution box parses the current signal to obtain the state information of the lamps.
