A lighting module including a housing with a cavity enclosed with a light-emitting surface and in which an LED is mounted connectable to a power source and possibly also to a control circuit. Between the LED and the light-emitting surface is arranged a transparent optical filter having an upper surface and a lower surface. The upper surface is adapted for the passage of a minor portion of light from the cavity of the housing to the light-emitting surface and, at the same time, the upper surface is adapted to reflect most of the light from the cavity of the housing back to the lower surface. On the lower surface of the transparent optical filter facing the LED is arranged a spatial optical structure adapted to scatter light from the cavity of the housing onto the upper surface and at the same time is adapted to scatter light reflected from the upper surface back to the spatial optical structure opposite the bottom of the cavity of the housing and possibly also opposite the side surfaces of the cavity of the lighting module.

Lighting module, in particular for a vehicle lighting device and a vehicle lighting device

The light-guiding optical unit () for a light device of motor vehicles comprises a light guide () that comprises at least one routing surface (), and at least one light source () to generate light rays (). The light-guide () further comprises a top surface () at least a part of which is constituted by the output surface (), and a bottom surface () opposite the top surface () and fitted with a prismatic structure () comprising reflective surfaces (). The routing surface () and the reflective surfaces () are mutually arranged in such a way that the routing surface (), by means of routing by refraction on this surface () or reflection from this surface (), directs light rays () to the prismatic structure () in such a way that it directly lights up only the reflective surfaces () with the light rays (), the reflective surfaces () being configured to direct light rays () that have fallen onto them this way directly from the routing surface () to the output surface () in such a way that the light rays () can exit from the light guide () through the output surface ().
