11692682 · 2023-07-04 · ·

A rear light unit of a vehicle is provided. The rear light unit includes an array of first light sources, arranged angularly offset along a first inner circumferential arrangement region, and an array of second light sources, arranged angularly offset at least along a second outer circumferential arrangement region concentric to the first inner circumferential arrangement region of the first light sources. The first and second light sources are made by one or more light-emitting diodes with which a light diffusing body is associated, the first light sources having a diffuser body in the form of a prismatic pinnacle, and the second light sources having a blade-shaped diffuser body along whose median axis emerges orthogonally a septum which enters the first inner circumferential arrangement region of the first light sources according to radial directions inserted between two successive light sources.

ROAD SURFACE DRAWING SYSTEM, LAMP SYSTEM, AND VEHICLE DISPLAY SYSTEM

A road surface drawing system includes a road surface drawing lamp that is provided in a vehicle and illuminates a road surface with a beam, and a controller that controls the road surface drawing lamp and draws, with a beam BM, a pattern PTN on the road surface ahead of the vehicle. The controller draws a pattern PTN instructing the vehicle to stop if a signal state of an upcoming traffic signal is a red light.

VEHICULAR LAMP
20220412532 · 2022-12-29 ·

A vehicular lamp is provided capable of enabling an observer to visually recognize the first and the second light-emitting areas as if they are integrated (connected) with each other when emitting light regardless of viewpoint positions. The vehicular lamp includes: a first light-emitting area and a second light-emitting area adjacent to each other in a horizontal direction with a gap; a third light-emitting area observed through the gap; a gap light-emitting unit disposed behind the gap; and a light control unit disposed between the gap and the gap light-emitting unit. The gap light-emitting unit includes a front and upper view light-emitting units disposed therebelow. The upper view light-emitting unit and the light control unit each have a lower portion extending downward. The light control unit includes an optical element controlling light from the upper view light-emitting unit by a predetermined angle upward so that the light passes through the gap.
