Illumination device and liquid crystal display device

摘要

An illumination device includes a metal base substrate in a flat planar shape, a plurality of LED modules, and a driving unit which drives each of the LEDs arranged on the metal base substrate. The LED modules have an organic substrate, a plurality of LEDs which are arranged on the organic substrate, a metal member, LED control signal terminals which are set on the edge of the organic substrate, and voltage feed terminals which are set on the edge of the organic substrate. The metal member corresponds to each LED and to which the heat from the LEDs is conducted, and which is electrically connected via a switch element from an electrode of the LED, and which penetrates the organic substrate toward its width direction from the LED mounting surface of the organic substrate and is exposed from the opposite surface.

主权项

1. An illumination device comprising:
(a) a metal base substrate in a flat planar shape; (b) a plurality of LED modules which each include:
an organic substrate;a plurality of LEDs which are arranged on the organic substrate;a plurality of metal members each of which is associated with a respective one of the LEDs and to which heat from the respective LEDs is conducted, the metal members each being electrically connected via a respective switch element to an electrode of the respective LED, and the metal members each penetrating the organic substrate in a width direction from an LED mounting surface of the organic substrate and being exposed from an opposite surface thereof;LED control signal terminals which are set on an edge of the organic substrate; andvoltage feed terminals which are set on the edge of the organic substrate;wherein 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, andwherein the LED control signal terminals and the voltage feed terminals which are adjacent to each other in the row direction and in the column direction are connected to each other and to a respective one of the LEDs via a respective switching circuit; and (c) a driving unit which drives each of the LEDs arranged on the metal base substrate.
