摘要： PROBLEM TO BE SOLVED: To provide a lighting system which can control light by the use of a dimmer, and adjusting illuminance even in a range of low illuminance. SOLUTION: The lighting system 1, receiving power supply through a dimmer 47 from an alternating-current power supply 45, includes a rectifying circuit 31, a step-up/down converter 37 connected to an output side of the rectifying circuit 31, an LED module 3 connected to an output side of the step-up/down converter 37, a dimming level detecting circuit 39 for detecting a dimming level of the dimmer 47, and a control circuit 41 controlling the step-up/down converter 37 so that current corresponding to the dimming level detected by the dimming level detecting circuit 39 is supplied to the LED module 3. Power activating the control circuit 41 is supplied from an output side of the step-up/down converter 37. COPYRIGHT: (C)2011,JPO&INPIT
