<P>PROBLEM TO BE SOLVED: To provide a lighting device that is capable of making remote control of only desired lightings out of a plurality of lightings arranged without fail, with certainty and simplicity, and capable of preventing malfunction of light emission condition switching. <P>SOLUTION: The lighting device 100 is formed with capability of switching the light emission conditions by way of operation light of a visible region which is output from an operation means arranged separately such as a laser pointer. The device includes: a light emission section 2 of a linear shape to irradiate illumination light; a light receiving section 3 of a linear shape arranged along the light emission section 2; a switching section 4 to switch the light emission conditions of the light emission section 2 based on output signals output from the light receiving section 3 when it receives the operation light; and a diffusion cover 14 arranged to cover the light receiving section 3 and to receive the operation light which passes through from outside to be diffused and makes incidence into the light receiving section 3 through linear diffusion in an extension direction of the light receiving section 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
