Patent ID: 8702295

Claim:
A flat light source module, comprising: a light guide plate having a light incident surface, a light exit surface, and a bottom surface, the light exit surface being opposite to the bottom surface, wherein the light incident surface further has a light incident curved surface, a first plane and a second plane opposite to the first plane, and the light incident curved surface is connected with the light exit surface and the bottom surface, wherein the light incident curved surface of the light incident surface further comprises a first curved surface and a second curved surface, the first curved surface is opposite to the second curved surface, the first plane connects the first curved surface and the second curved surface, and the second plane connects the first curved surface and the second curved surface; a plurality of flexible circuit boards disposed along the light incident curved surface of the light guide plate, wherein the flexible circuit boards comprise a plurality of metal copper-clad laminates, the metal copper-clad laminates are disposed along the first curved surface and the second curved surface, wherein a plurality of metal core printed circuit boards are disposed along the first plane and the second plane; and light emitting devices disposed on the flexible circuit board and the metal core printed circuit boards, and the light emitting device disposed on the flexible circuit board having a light emitting surface facing the light incident curved surface, wherein the light emitting surface of the light emitting device is parallel to a tangent line of the corresponding light incident curved surface of the light guide plate.
