An automotive light including: a rear casing, which is substantially basin-shaped and is structured in such a way as to be fixed on the vehicle body; a front half-shell, which is arranged to close the mouth of the rear casing and is provided with at least a transparent or semitransparent portion; and at least one lighting assembly, in turn including a platelike light-guide body, which extends within the rear casing in such a way as to place a front sidewall thereof so that it faces the transparent or semitransparent portion of the front half-shell and a rear sidewall thereof so that it faces the bottom of the rear casing; and a light-emitting device, which is located within a transverse slot that extends within the platelike light-guide body, from the rear sidewall to the front sidewall, remaining substantially perpendicular to the midplane of the platelike light-guide body and substantially parallel to the optical axis of the automotive light. |

1. An automotive light (1) comprising: a rear casing (2), which is substantially basin-shaped and is structured in such a way as to be fixed on the vehicle body; a front half-shell (3), which is placed in order to close the mouth of the rear casing (2) and is provided with at least a transparent or semitransparent portion (3a); and at least one lighting assembly (4), which emits light upon command and is located within the rear casing (2) in such a way as to be able to backlight said transparent or semitransparent portion (3a) of the front half-shell (3);
said lighting assembly (4) in turn comprising a platelike light-guide body (5), which extends within the rear casing (2) in such a way as to arrange a front sidewall (6) thereof so that it faces the transparent or semitransparent portion (3a) of the front half-shell (3), and a rear sidewall (7) thereof so that it faces the bottom of the rear casing (2); and a light-emitting device (8), which is located inside the rear casing (2) and is structured so as to direct the light produced within the platelike light-guide body (5), in such a way that the light can reach, and exit from, the front sidewall (6); the automotive light (1) being characterized in that the rear sidewall (7) of the platelike light-guide body (5) has a curved profile having a substantially parabolic shape, with the concavity facing the front sidewall (6), and is provided with a transverse slot (9), which extends within the platelike light-guide body (5), from the rear sidewall (7) to the front sidewall (6), remaining substantially perpendicular to the midplane of the platelike light-guide body (5) and substantially parallel to an optical axis (A) of the automotive light in such a way as to divide the rear sidewall (7) into two semiparabolic portions (7a, 7b; 7c, 7d, 7e), each of which follows a specific curved profile with complex parabolic geometry; in that the light-emitting device (8) engages said transverse slot (9) and is provided with two light sources (10), which are positioned within the transverse slot (9), each directly facing a respective inner sidewall (11) of the platelike light-guide body (5) in such a way as to direct the light produced within the platelike light-guide body (5) towards a corresponding semiparabolic portion (7a, 7b; 7c, 7d, 7e) of the rear sidewall (7); and in that at least one of the two semiparabolic portions (7a, 7b; 7c, 7d, 7e) of the rear sidewall (7) is shaped in such a way as to direct the light rays coming from the light source (10) towards the front sidewall (6) in such a way that the light rays exiting from the front sidewall (6) are collimated in a first direction (d1) substantially parallel to said optical axis (A) of the automotive light, and also at least in a second direction (d2, d3) inclined with respect to the optical axis (A) of the automotive light by a first pre-set angle. |
