<p>PROBLEM TO BE SOLVED: To substantially reduce standby power of a luminaire. SOLUTION: In this lighting system, a lamp 4 is connected to an AC power supply 1 through switching means 2a, 2b and a lighting device, the lighting device 3 is controlled by a microcomputer 5 connected from an output side, and an output signal of a first receiving part 6 capable of receiving a remote control signal R is inputted in the microcomputer 5, and a second receiving part 9 which is connected to the AC power supply 1 without going through the switching means 2a, 2b and is capable of receiving the remote control signal R and an amplifier 10 to amplify its output signal are provided. When a signal is generated in the output of the second receiving part 9 by receiving the remote control signal R, the switching means 2b is switched on, and the first receiving part 6 and the microcomputer 5 are actuated. When the output signal of the first receiving part 6 is inputted in the microcomputer 5 by receiving the remote control signal R, the microcomputer 5 outputs a control signal to keep the switch means 2 a in ON condition, if the remote control signal R is a command signal for lighting the lamp 4.</p> |
