<p><P>PROBLEM TO BE SOLVED: To provide an infrared remote controller for a fluorescent lamp, and a lighting system which have no problems of malfunction and non-operation by the argon emission of the fluorescent lamp. <P>SOLUTION: The infrared remote control system for a fluorescent lamp includes: the fluorescent lamp FL; a fluorescent lamp lighting device LOC to light the fluorescent lamp at a high frequency; an infrared receiving means IS; an electric filter F which is inserted in a circuit to which an electric output of the infrared receiving means is transmitted, in a pass area of which a carrier wave frequency of an infrared remote control signal is included and in an attenuation area, having a higher frequency than the pass area, of which the lighting frequency of the fluorescent lamp is included; an infrared remote control signal receiver IRR which determines the infrared remote control signal on the basis of an electric signal having passed through the filter, and controls a discharging lamp lighting device; and an infrared remote controller IRT which modulates the carrier wave by an operational signal of the fluorescent lamp lighting device, and generates and projects the infrared remote control signal. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
