Damage due to heat in a case where a projection lens having lower heat resistance performance is used is avoided.A control section controls a light source drive section in such a way that the output from a light source is allowed to be increased up to a first value in a case where a projection lens is a first projection lens and controls the light source drive section in such a way that the output from the light source is allowed to be increased up to a second value different from the first value in a case where the projection lens is a second projection lens having heat resistance performance different from that of the first projection lens.
