Abstract: A flat light source with U-shaped configuration is proposed which can provide substantially uniform surface illumination. The flat light source includes a first transparent portion for use for illumination which may be composed of a first substantially flat light transmission means, a second transparent portion for use as bypass light guide which may be composed of a second substantially flat light transmission means, and a light coupling portion for use as light coupling between said first and second transparent portions, which may have at least one optical prism. The first and second transparent portions which may be positioned substantially parallel each other form a first and second substantially linear cross sections of a substantially U-shaped configuration. The light coupling portion which is positioned near a bottom between said first and second transparent portions forms a substantially bent (or non-linear) cross section of the U-shaped configuration. Thereby the flat light source composed of the first transparent portion, the second transparent portion and the light coupling portion forms the U-shaped configuration as a whole.

The flat light source comprises a first light transmission means for illumination with relatively high refractive index, a second light transmission means for bypass light guide including at least one light guide having relatively high refractive index and a light coupling means making light coupling between the both first and light transmission means for changing direction of light rays, wherein the light rays output from the second light transmission means are changed in direction in order to input into the first light transmission means. A plurality of optical fibers may be used as the light-guides for light bypassing, in which they are aligned at least in one line in the second light transmission means, by which almost all incident light rays can be transmitted along entire length of the second light transmission means with minimized loss. The light coupling means may be composed of at least one optical element with high reflactive index, having a cross-sectional shape selected from a group of a trapezoidal, a triangular, a half-circular and a "U" shape. The first light transmission means may have a first terminal surface and the second light transmission means may have a second terminal surface.
