In this control circuit, based on a reference potential generated in a high-voltage generating circuit, a comparator outputs an over-light incidence discrimination signal to the outside of a module. It is revealed that, when an over-light incidence discrimination signal switched to high level from low level is outputted to the outside, data to be outputted from an anode terminal has no reliability while data has reliability before switching. Therefore, detection can be performed while determining reliability.
