Abstract (en)

[origin: EP1881263A1] The device (10) has a light guiding plate (12) with a coupling area shaped such that light rays emitted by a light source (28) e.g. side emitter LED, are propagated at the area. The plate is shaped such that the rays are propagated in meridian incident propagation planes normal to the plate between the source and a rear reflecting edge and in reflected propagation planes normal to the plate between the edge and an output edge (18). The rear edge is shaped such that the reflected planes have an orientation with respect to an optical axis to allow the device to emit a linear light beam.
