The invention discloses a direct-current power supply and a direct-current power supply LED streetlamp system. The direct-current power supply comprises a single-phase rectifying circuit, a power supply output distribution circuit and a plurality of direct-current output ports. The first end of the single-phase rectifying circuit is connected in a single-phase sine power supply, and the single-phase rectifying circuit is used for converting the single-phase sine power supply into a first direct-current power supply. The first end of the power supply output distribution circuit is connected with the second end of the single-phase rectifying circuit. The power supply output distribution circuit is used for reducing the voltage of the first direct-current power supply to obtain a second direct-current power supply. The direct-current output ports are connected with the second end of the power supply output distribution circuit and used for outputting the second direct-current power supply. The direct-current out
