Abstract

An illumination device for a motor vehicle light has a plate-like transparent light guiding body (LGB). Light sources are arranged on a narrow side of the LGB and emit light that enters the LGB and propagates therein in a first main light propagation direction (X) to the opposite narrow side. At least some of the light rays (S), incident on the front main surface (FMS) of the light propagating in the Xdirection are totally reflected at the FMS such that the light strikes a rear main surface (RMS), which has an exit structure. At least some of the light rays (S') which are totally reflected at the FMS and which strike the RMS exit the LGB via the exit structure. A reflector surface, which is arranged opposite the RMS, is designed such that light rays (S″) emerging from the RMS and striking the reflector surface are deflected by the reflector surface in the direction of the LGB in a second light propagation direction (X) and the deflected light rays (S′″) pass through the RMS and the FMS and are emitted into an area in front of the illumination device to form a light distribution.
