Title:
AUTOMOBILE LIGHTING SYSTEM, AUTOMOBILE LIGHTING ASSEMBLY AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2019/100639
Kind Code:
A1
Abstract:
An automobile lighting system, an automobile lighting assembly comprising the automobile lighting system and an automobile comprising the automobile lighting assembly. The automobile lighting system includes a light source (1), reflectors (2, 2a, 2b), a shielding plate (3) and a lens (4); the lens (4) includes a reflecting surface (4a) and a refracting surface (4b) opposed to the reflecting surface (4a); when external parallel lights are incident on the lens (4), the lights transmit outward of the lens (4) and are converged to form a focal point (4c) after primary refraction by the refracting surface (4b), reflection by the reflecting surface (4a) and secondary refraction by the refracting surface (4b) in sequence; and the reflectors (2, 2a, 2b) comprise a perifocus and an apofocus; the light source (1) is disposed at the position of the perifocus of the reflectors (2, 2a, 2b), and the apofocus of the reflectors (2, 2a, 2b) is disposed nearby the focal point (4c) of the lens (4); the shielding plate (3) has a shielding plate cut-off line of the same shape as a light-shade cut-off line (a) of a lower beam shape of the automobile light, and the shielding plate cut-off line is located at the position of the focal point (4c) of the lens (4). The lens (4) changes a light path after twice refraction of the light by the refracting surface (4b) and one reflection of the light by the reflecting surface (4a), thereby significantly enhancing the light path changing ability, reducing a focal length and improving the chromatic dispersion.
