Abstract
A lighting apparatus is provided which includes a drive section which applies electric current to a light source which is a semiconductor element emitting light with application of electric current, at least one heat sink which is mounted with the light source and transfers heat generated by the emission of the light source, and a temperature measurement section which is mounted to the heat sink and measures temperature of the heat sink which is used for estimating temperature of the light source. The light source and the drive section are mounted to the same heat sink or to the heat sinks which are thermally coupled to each other.
