Abstract:
1. A light source control device adapted to control a light source device having a plurality of solid-state light sources connected in series to each other, the light source control device comprising: a detector adapted to detect at least one of a voltage applied to the solid-state light sources and a current supplied to the solid-state light sources; and a control section adapted to determine whether or not discontinuity of at least one of the voltage and the current is present using a detection result of the detector, and change control of one of the current and electrical power performed on the light source device if it is determined that the discontinuity is present, wherein the control section includes a storage section adapted to store the detection result of the detector, and compares the detection result of the detector and the detection result stored in the storage section with each other to thereby determine whether or not the discontinuity is present.
