<p><P>PROBLEM TO BE SOLVED: To provide a lighting apparatus wherein a lighting device part can be automatically inspected even if abnormality occurs in a master unit transmitting an inspection instructing signal. <P>SOLUTION: This lighting apparatus is provided with a master unit 1 and a slave unit 2 having a communication part 20 for communicating with the master unit 1 and a guide light lighting device part 21. The communication part 20 transmits an inspection signal Y1 to inspect the lighting device part 21 by receiving an inspection instructing signal X1 from the master unit 1 and receives the inspection result as an inspection result signal Y2 from the lighting device part 21 to transmit it to the master unit 1 as the inspection result signal Y2, and the lighting device part 21 inspects the lighting device part 21 by receiving the inspection signal from the communication part 21 to transmit the inspection result to the communication part 20. In this lighting apparatus, an abnormality detecting part 22 to detect abnormality of the master unit 1, a control part 23 to inspect the lighting device part 21 by the slave unit 2 alone when the abnormality detecting part 22 detects abnormality, and a memory part 24 to memorize the result of the inspection are provided in the slave unit 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
