发明名称 Light source control device and projector
摘要 A light source control device is for controlling a solid-state light source array having a plurality of solid-state light sources connected in series to each other, and includes a detector (a current detection resistor, voltage detection resistors, and operational amplifiers) adapted to detect at least one of a voltage applied to the solid-state light source array and a current supplied to the solid-state light source array, and a control circuit 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 solid-state light source array if it is determined that the discontinuity is present.
