<P>PROBLEM TO BE SOLVED: To provide a lighting system capable of preventing a power supply part from being thermally affected by an LED, preventing a continued arc, and coping with an increase of an optical output from the LED. <P>SOLUTION: The power supply part 13 is separated from a light source 14, an input power source is converted into a predetermined voltage and converted into an AC power at the power supply part 13, and the AC power is supplied to the light source 14 via a cable 15. The power supply part 13 is prevented from being thermally effected by the LED 29 in the light source 14, and the continued arc generated in a circuit of the light source 14 is prevented by the voltage of the AC power supplied to the light source 14 becoming 0V at every cycle. <P>COPYRIGHT: (C)2011,JPO&INPIT |
