Abstract

In the present invention, an illumination device comprises a light source, a light source drive circuit, a first control unit, a non-volatile second storage unit, and a first communication unit. The light source drive circuit supplies power to the light source. The control unit includes a non-volatile first storage unit that stores a control program stipulating a control operation relating to control of the light source, and a first processing circuit that executes the control program to control the light source drive circuit. The first communication unit communicates with an external device. The first control unit receives an update program for the control program through the first communication unit from the external device, stores the received update program in the second storage unit, and rewrites the control program stored in the first storage unit according to the update program stored in the second storage unit.
