Abstract
A light appliance, particularly a signal lamp for engine vehicles, is provided that comprises a primary optical unit (4) with at least one light source (8), a secondary optical unit (5) comprising at least one areal electro-luminescent diode (12) for emitting light with its light emitting surface (121), and at least one reflective surface (61) of a reflective device (6) for reflecting light from the primary optical unit (4) falling onto the reflective surface (61). At least one of the electro-luminescent diodes (12) of the secondary optical unit (5) is arranged, with respect to some of the reflective surfaces (61), in such a way that at least a part of the light beams from the primary optical unit (4), directed to the reflective surface (61), passes before falling onto the reflective surface (61) and/or after reflection from reflective surface (61) through light emitting surface (121) of diode (12).
