PROBLEM TO BE SOLVED: To provide a power supply, a lighting apparatus and a light control system for the lighting apparatus, producing a stable lighting state of a semiconductor light-emitting element.SOLUTION: The power supply includes: DC output generation means including a primary coil and first and second secondary coils, for outputting DC power in response to a light control signal from light control means; and control means for, after the output of the light control signal from the light control means, controlling the DC power output from the DC output generation means according to the light control signal and starting lighting control of the semiconductor light-emitting element according to the light control signal. The first secondary coil of the DC output generation means outputs the DC power to the semiconductor light-emitting element. Also, the second secondary coil of the DC output generation means outputs the DC power to the control means. |
