<p>PURPOSE:To facilitate handling of a luminaire by providing a remote controller part for the luminaire with a lamp replacement time display function and a luminaire cleaning time display function, and by enabling economically good usage of a luminaire. CONSTITUTION:The clock of a clock counter part 1 is transmitted to a lighting time integration part 3 according to the information on the lighting condition of a luminaire, which is detected by a lighting condition detection means 2. The total lighting time of the lighting time integration part 3 is compared with the information on the lamp life of a lamp replacement time memory part 4, by a comparison part A 5, and is displayed on a display part A6. The total utilization time of the fitting integrated by a clock counter integration part 8 for integrating the clock of the clock counter part 1, is compared with the degree of dirt accumulation of a luminaire cleaning time memory part 9, and the time elapse variation of the lumen maintenance factor, by a comparison part B10, and is displayed on a display part B11.</p> |
