Title:
VEHICLE LAMP OPTICAL ELEMENT ASSEMBLY, VEHICLE LIGHTING MODULE, VEHICLE LAMP, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/233297
Kind Code:
A1
Abstract:
A vehicle lamp optical element assembly, a vehicle lighting module, a vehicle lamp, and a vehicle. The vehicle lamp optical element assembly comprises a primary optical element (11) and a secondary optical element (21). The primary optical element (11) comprises at least one light entrance part (112), a light transmission part (113), and a light exit part (114) sequentially provided along a light exit direction. Optical axes of the light entrance parts (112) on either side of the primary optical element (11) incline towards an optical axis (211) of the secondary optical element and the light exit part (114) is a concave arc surface; or the direction of the optical axis of the light entrance part (112) is the same as that of the optical axis (211) of the secondary optical element and the horizontal cross-sectional line and/or vertical cross-sectional line of the light exit part (114) is configured as a curved line protruding forward. The present invention uses a particular design concerning the cooperation between the primary optical element (11) and the secondary optical element (21), such that a vehicle lighting module has a small volume while ensuring light effects, and can be adapted to narrow and compact vehicle lamp modeling.
