A flat light guide () for a vehicle lighting device, which includes a rear end () and a front end with a light output surface (), the light guide () being defined between the two ends by a pair of side surfaces (). The light guide () has a base plane (X-Y) and at its rear end () is provided with at least one collimating element () arranged transversely or obliquely with respect to the plane (X-Y). Opposite the collimating element () is arranged an obliquely inclined reflective surface () to reflect light from the collimating element () into the flat light guide (). The collimating element () is adapted for the light input from the light source into the light guide () which further guides the light between the side surfaces () to the output surface ().

Flat light guide for a vehicle lighting device and a vehicle lighting device

The invention relates to a light guiding optical system comprising at least two light guides (), to which is assigned a light unit () with at least one source () of light. The inner light guide () is provided with an input surface () with which it is situated opposite the light unit () and is further is provided with a broken stepped transition surface (), which comprises at least one decoupling surface () and at least one reflective surface (), whereby the broken stepped transition surface () of the inner light guide () is associated with an input surface () of a coupling light guide () which comprises at least one coupling surface ().
