PROBLEM TO BE SOLVED: To provide a lighting system capable of avoiding a light from keeping lit up when used like an all-night light.SOLUTION: A lighting system 1 includes: an LED 5 as a light source; a control circuit 7 for adjusting the output of the LED 5 for lighting up; and an off-timer 11 for making the LED 5 put out the light after passing 10 hours from the start of lighting up. Only in an "all-night light mode" that makes the LED 5 light up by a prescribed output lower than a rating output, the control circuit 7 makes the off-timer 11 automatically start working to put out the light of the LED 5 automatically, so that the LED 5 cannot be kept lighting up. |
