Patent attributes
An illumination device includes a light source unit having a light emitting panel, and a mounting unit attached to a non-light-emission surface of the light source unit and provided with a circuit board for controlling energization of the light emitting panel. The mounting unit includes a connection terminal to which an external conductor for electrically interconnecting the circuit board and an external device is connected. The connection terminal is arranged inward of an outer peripheral end of a surface of the mounting unit to which the light source unit is attached. A clearance for passing the external conductor therethrough is formed between the light source unit and the mounting unit in a state that the external conductor is connected to the connection terminal and the mounting unit is attached to the light source unit.
