A vehicle light (1) having a multi-reflex optical system comprising a light source (2), at least one pair of ellipse group reflecting surfaces (31(L, R), 32(L, R)) located so as to surround the light source (2), each ellipse group reflecting surface (31L, 31R, 32L, 32R) being symmetrical relative to the light source (2) and having a first focus (f1) in the vicinity of the light source (2), a second focus (f231, f232), and its longitudinal axis (Y) approximately perpendicular to an optical axis (X) of the vehicle light (1), the same number of parabolic group reflecting surfaces (41L, 41R, 42L, 42R) as the ellipse group reflecting surfaces (31L, 31R, 32L, 32R) located substantially linearly, each parabolic group reflecting surface (41L, 41R, 42L, 42R) having a focus at the second focus (f231, f232) of the corresponding ellipse group reflecting surface (31L, 31R, 32L, 32R) and a longitudinal axis substantially parallel to the optical axis (X) of the vehicle light (1), and at least one shade (5) located in the vicinity of one of the second foci (f231, f232) of the ellipse group reflecting surfaces (31L, 31R, 32L, 32R) to provide a predetermined shape to the luminous flux from the corresponding ellipse group reflecting surface (31L, 31R, 32L, 32R). <IMAGE> |
