PROBLEM TO BE SOLVED: To thermally separate an LED and a control unit controlling the LED to have each hardly thermally affected by the other, and efficiently cool the LED and the control unit. SOLUTION: The device includes a first case housing an LED substrate, a second case housing an LED control unit, a coupling member coupling the first case and the second case in a substantially thermally separated state, a first heat dissipation structure fitted to one of the opposing faces of the first case and the second case, and a second heat dissipation structure fitted to the other of the opposing faces of the first case and the second case in a way separated from the first heat dissipation structure.
