  Next, life end prediction processing performed in the CPU 16d will be described below. In the following, for the sake of simplicity, the case where the end of life of the lighting fixture 12a provided in the room RA is predicted will be described as an example.

  The CPU 16d includes information indicating the lighting time of the light source 121a, information indicating the current value RAI at the lighting time, information indicating the set illuminance LRA at the lighting time, among the pieces of information stored in the storage device 16b. , And the power consumption PA, which is the power consumed in the light source 121a, is calculated based on the acquired current value RAI. That is, according to such processing of the CPU 16d, the power consumption PA required to turn on the light source 121a is calculated.

  The predetermined power consumption PTH is set, for example, as the power when the amount of illumination light required to change the illuminance of the room RA to the set illuminance LRA is the maximum amount of light that can be generated from the light source 121a.

  On the other hand, the CPU 16d is not limited to the process described above, and may perform the process described below as the end of life prediction process, for example.

  The CPU 16d includes, from among the pieces of information stored in the storage device 16b, information indicating a lighting time and a lighting time of the light source 121a, information indicating a current value RAI during a lighting time from the lighting time to the lighting time, Are calculated, and based on the acquired current value RAI, a power consumption amount QA, which is the amount of power consumed in the light source 121a during the lighting time, is calculated.

  Then, based on the calculation result of the power consumption amount QA in each lighting time of the light source 121a, the CPU 16d, for example, the cumulative power consumption amount QK that is a value obtained by accumulating the power consumption amount QA included in the calculation result every predetermined period. And the cumulative lighting time τ have a correlation as shown in FIG. 5, and based on the detected correlation, the cumulative power consumption QK is increased and the predetermined cumulative power consumption is increased. The cumulative lighting time τL estimated to reach the quantity QTH is predicted as the end of life of the lighting fixture 12a. FIG. 5 is a diagram illustrating an example of a correlation between the cumulative lighting time τ and the cumulative power consumption QK.

  Note that the predetermined cumulative power consumption amount QTH is set as, for example, the power amount when the maximum light amount of the illumination light emitted from the light source 121a is equal to or less than the predetermined light amount.

  On the other hand, the CPU 16d is not limited to the process described above, and may perform the process described below as the end of life prediction process, for example.

  The CPU 16d obtains information indicating the lighting time of the light source 121a, information indicating the set illuminance LRA at the lighting time, and the actually measured illuminance LA1 (or LA2) at the lighting time from each piece of information stored in the storage device 16b. Information to be obtained is acquired.

  The CPU 16d detects, for example, that the lighting time T of the light source 121a and the actually measured illuminance LA1 (or LA2) have a correlation as shown in FIG. Based on this, the first lighting time TM estimated that the measured illuminance LA1 (or LA2) decreases and reaches the predetermined illuminance LTH is predicted as the end of life of the lighting fixture 12a. FIG. 6 is a diagram illustrating an example of a correlation between the lighting time T and the actually measured illuminance LA1 (or LA2).

  Here, in the present embodiment, for example, information indicating the lighting time and extinguishing time of the light source 121b, information indicating the current value RBI, information indicating the set illuminance LRB, and information indicating the measured illuminance LB1 (or LB2). Based on the above, it is also possible to predict the end of life of the lighting fixture 12b by performing the same processing as the processing for predicting the end of life of the lighting fixture 12a. That is, according to the present embodiment, the end of life of the lighting fixture can be predicted according to the actual use situation.

  In the present embodiment, the association between the electric devices 13a and 13b and the lighting fixtures 12a and 12b is set by the communication control device 15 or the information processing device 16, so that the lifetime based on the actually measured illuminance LB1 (or LB2). Predictions can be made. For example, by associating the electrical devices 13a and 13b installed in the same room with the lighting devices 12a and 12b, it is possible to detect the illuminance of the area irradiated by the lighting fixtures 12a and 12b. In addition, when the electric devices 13a and 13b are devices having a light emitting unit such as a television device, the actually measured illuminance may be obtained in consideration of control information of the electric devices 12a and 12b. For example, assuming that the communication control device 15 is configured to receive the control states and detection results of the electric devices 13a and 13b, the light emitting units of the electric devices 13a and 13b do not emit light (for example, a standby mode). And the illuminance when the lighting fixtures 12a and 12b are in the lighting state may be detected as the actually measured illuminance LB1 (or LB2). In this way, by measuring the measured illuminance in consideration of information on other electrical devices, it is possible to perform more accurate life prediction.

These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
