Abstract
An automotive light is provided that includes a light-guide plate extending inside the rear body of the light remaining substantially parallel to the light reference optical axis close up to the front lenticular hemi-shell of the light with its front side edge facing the strip-shaped transparent or semi-transparent portion of the front lenticular hemi-shell, and a linear-extending light source directing emitted light towards the inside of the light-guide plate through the rear side edge of the same light-guide plate. The rear side edge of the light-guide plate includes a serrated profile with teeth substantially triangular in shape oriented so that a first inclined edge of the tooth is arranged locally substantially perpendicular to the optical reference axis. The light source includes a row of spaced LEDs facing the rear side edge, each LED facing a respective tooth of the rear side edge so as to direct/project emitted light through the first inclined edge of the tooth. The lighting assembly also includes a series of optical collimators interposed between a diode and a corresponding tooth of the rear side edge of the light-guide plate to deflect light rays towards the corresponding inclined edge of the tooth and collimating the rays in a direction substantially parallel to a collimation axis substantially coplanar to the light-guide plate and inclined with respect to the optical reference axis of the light by greater than 0°.
