The integrating unit 18C updates each lighting integrated time by adding the lighting time measured by the measuring unit 18B to each lighting integrated time stored in the storage unit 17. For example, when the light source unit 12 is lit at the red dimming level “2”, the integrating unit 18C performs measurement at the lighting integrated time of the red dimming level “2” stored in the storage unit 17. The accumulated lighting time of the red light control level “2” is updated, and the accumulated lighting time of other primary color light sources and other light control levels of red are not updated.

The energization integration time of the substrates 11 and 13 is reset according to the reset signal. Specifically, the accumulating unit 18C sets the energization accumulated time of the replaced substrates 11 and 13 to zero. For example, when the panel substrate 11 is replaced and a reset signal for resetting the integrated energization time of the panel substrate 11 is received, the integrating unit 18C sets the integrated energization time of the panel substrate 11 to zero.

Remembered. At that time, the integration unit 18C sets the energization integration time of the dimming control board 14 to zero when a reset signal for resetting the energization integration time of the dimming control board 14 is received. Further, the integrated energization time of the light control board 14 may be reset when the integrated energization time of the panel board 11 is stored in the storage unit 17 based on the control information from the console 50.

  In addition, here, an example of resetting the integrated energization time of the lighting device 10 has been described. However, the present invention is not limited to this, and a reset signal is transmitted to various appliances compatible with the RDM standard and connected to the lighting system 1. And the energization integration time measured in various instruments can also be reset for each instrument.

  At time t0, power is supplied from the distribution board 100, and the substrates 11, 13, and 14 are energized. Therefore, the first energization integration time and the second energization integration time increase according to the energization time. In addition, since the light source unit 12 is turned on, the lighting integrated time increases according to the lighting time.

The second energization integration time is a predetermined time close to the lifetime of the panel substrate 11.

  When the substrates 11, 13, and 14 are in a non-energized state at time t12, the first energized integrated time and the second energized integrated time are maintained at values immediately before the non-energized state.

  Here, when the panel substrate 11 is replaced by an operator or the like, and a reset signal indicating that the panel substrate 11 has been replaced is received at time t13, the second energization integration time is reset to zero.

  If the board | substrates 11, 13, and 14 will be in an energization state in time t14, 1st energization integration time will increase from the memorize | stored value. On the other hand, the second energization integration time increases from zero because it has been reset.

  As described above, when the substrates 11, 13, and 14 are replaced and the reset signal is received, the lighting device 10 resets the accumulated energization time of the replaced substrates 11, 13, and 14 according to the reset signal, and the substrates 11 and 13 are replaced. , And calculates and stores a different energization integration time for each of 14.
