The illuminance data processor 202 is used to receive the illuminance data detected by each detector 201, and collect and encode each illuminance data and send it to the analysis processor 203, so that the analysis processor 203 can analyze the illuminance data and correspond to each Light source 100.

The manufacturer of the light source 100 can provide two kinds of graphs of the light source 100 , the graph of the relationship between the lumen value of the light source and the usage time ( FIG. 4 ), and the graph of the relationship between the usage time of the light source and the number of remaining luminous lamps ( FIG. 5 ).

As shown in FIG. 4 , in the diagram of the relationship between the lumen value of the light source and the use time (Lurninous flux behavior, the light source is a metal halide lamp HQI 400W/N), each time corresponds to a preset threshold. The middle area of the two curves in the figure is the normal lumen value range of the light source 100 , and the present invention takes the lowest value of the normal range in the corresponding time as the preset threshold value. The analysis processor 203 is used to receive the illuminance data of each detector 201, calculate the lumen value of each light source 100 according to the illuminance data and compare the lumen value with the preset threshold value, if the lumen value at the time point is lower than the lumen value at the time point The threshold value indicates that the light source is working abnormally, and its lifespan will be exhausted, so it needs to be replaced in time; it does not need to be replaced when the light source is damaged and extinguished, so as to ensure the normal production of the workshop.
