VEHICLE LAMP OPTICAL ASSEMBLY, ILLUMINATION OPTICAL DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/198721
Kind Code:
A1
Abstract:
A vehicle lamp optical assembly, an illumination optical device, and a vehicle. The vehicle lamp optical assembly comprises a first optical element (1) and a second optical element (2) integrally formed with the first optical element (1), wherein the first optical element (1) comprises a first light incident portion (11) and a first light guiding channel (12) connected to a light-emitting end of the first light incident portion (11), the second optical element (2) comprises a second light incident portion (21) and a second light guiding channel (22) connected to a light-emitting end of the second light incident portion (21), the end of the first light guiding channel (12) that is away from the first light incident portion (11) is connected to the end of the second light guiding channel (22) that is away from the second light incident portion (21) so as to form an interface (a), the refractive index of the first light guiding channel (12) is less than the refractive index of the second light guiding channel (22), and a light transmission direction of the first light guiding channel (12) and a light transmission direction of the second light guiding channel (22) are opposite to each other and form an included angle. The vehicle lamp optical assembly can be used for improving the visibility of a distant position under a low beam, is highly integrated, and is low-cost.
