PROBLEM TO BE SOLVED: To provide a lighting fixture, a lighting system, and a lighting power control module thereof.SOLUTION: The lighting power control module has a plurality of light sources and a current control circuit. The current control circuit includes a light source drive unit, a switch, and a light control module. The light source drive unit is used for outputting direct current source and providing a plurality of switch control signals. The switch is electrically connected between the light source drive unit and the light source, and is used for selectively supplying direct current to at least one light source by a switch control signal. The light control module determines the switch control signal with a user control signal to adjust the value of the direct current. The lighting fixture has the lighting power control module, a housing, and a power source line. The lighting system has the lighting fixture and an AC-DC modularization power supply device having a plurality of AC-DC power supply modules. |
