PROBLEM TO BE SOLVED: To provide a lighting system with its output line shortened and high frequency noise reduced. SOLUTION: DC power supply part 1 for outputting DC voltage by being supplied with electric power from AC power supply AC and an inverter part 2 for outputting a high frequency constant current by being received output from DC power supply part 1 are provided. The DC power supply part 1 and the inverter part 2 are connected to each other via a power supply line 17 for DC. Between the output terminals of the inverter part 2, an output lien 3 for forming a loop circuit is placed in connection. The inverter 2 is provided in an apparatus main body together with an illumination load 5 and in the apparatus main body, a current transformer 4 for supplying the secondary output to the illumination load 5 is provided with the output line 3 as the primary side. |
