Abstract
A light device for motor vehicles comprises a carrying housing covered by a translucent cover and an inner chamber where an optical system is mounted containing a light guide with a light guide body for guiding the light generated by the light source and its emission as a light beam through one or more output light surfaces out of the light guide, one or more flat electroluminescence diodes and a reflective element for reflection of light emitted from one or more light emitting surfaces of the flat electroluminescence diode. The electroluminescence diode is attached to the light guide. The light guide is configured to emit the light beam essentially in an optical axis direction, and the reflective element is adapted to reflect light of the electroluminescence diode to a direction that is essentially parallel to the direction of the optical axis.
