Abstract:
1. A linear light source apparatus comprising: a thermally conductive frame; an LED; an LED drive circuit substrate that drives the LED and comprises a substrate face; a flexible electric supply pattern substrate that comprises an LED mounting face, a connecting face and an electric supply pattern, the electric supply pattern corresponds to an anode or a cathode of the LED wherein an electric power is supplied to the LED from the LED drive circuit substrate via the electric supply pattern, the electronic supply pattern comprises a first connecting portion and a second connection portion, the first connecting portion is located at the LED mounting face and is configured to be connected with the anode or the cathode, the second connecting portion is located at the connecting face and is configured to be connected with a third connecting portion of the LED drive circuit substrate; a light guide member that propagates a light inputted from the LED; a holding portion that holds the light guide member and the heat sink that is adjacent to the thermally conductive frame so that heat is conducted into the thermally conductive frame; wherein an opposite side face of the electric supply pattern substrate that is opposite from the LED mounting face is attached to the heat sink, so that heat generated by the LED is conducted into the heat sink through the electric supply pattern substrate; wherein the LED drive circuit substrate is arranged along the thermally conductive frame; wherein a covering face of the heat sink, to which the opposite side face is attached, is perpendicular to a length direction of the light guide member, the LED mounting face is perpendicular to a length direction of the light guide member, and is perpendicular to the substrate face of the LED drive circuit substrate; and wherein a bent portion is formed in the flexible substrate between the LED mounting face and the connecting face so that the connecting face is parallel to the length direction of the light guide member and is parallel to the substrate face of the LED drive circuit substrate.
