<p>An illumination device has a plurality of LED modules and a driving unit. The LED modules have: a metal base substrate formed in a planar shape; an organic substrate; a plurality of LEDs arranged on the organic substrate; a metal member provided so as to correspond to each of the LEDs, conduct heat from the LED, be electrically connected via a switch element from one of the electrodes of the LEDs, go through the organic substrate along the width direction thereof from the LED mounting surface of the organic substrate, and be exposed from the opposite surface of the organic substrate; LED control signal terminals provided to the edge side of the organic substrate; and voltage feed terminals provided to the edge side of the organic substrate. The LED modules are arranged along the row direction and the column direction so as to be capable of attaching to and detaching from the metal base substrate, the LED control signal terminals and the power feed terminals that are adjacent to each other along the row direction and the column direction being connected to each other. The driving unit drives each of the LEDs arranged on the metal base substrate.</p> |
