Title:
VEHICLE LAMP OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/078114
Kind Code:
A1
Abstract:
A vehicle lamp optical element (1). One end of the vehicle lamp optical element (1) is provided with a plurality of light-condensing structures (11), and the other end is provided with a light exit surface (12), and the light exit surface (12) is an arc-shaped surface that protrudes outwards. The vehicle lamp optical element has the following advantages: 1. the primary optical element and the secondary optical element of the prior art are integrated into one piece, and the relative position accuracy of the two no longer needs to be ensured during installation, which may better ensure the stability of the light shape of a vehicle lamp while also reducing the size of a vehicle lamp module; 2. a partition slot (2) is provided to achieve secondary light distribution; 3. a pointed slot (3) is provided to replace existing light-shielding plates, so that the structure of the vehicle lamp module is simplified and the overall size is reduced; and 4. a low beam part (16) and a high beam part (17) are provided, and a partition slot (4) is provided on the bottom surface of the high beam part (17), or a wedge-shaped gap (5) is provided between the two, so that high beam and low beam functions are simultaneously achieved in the integrated vehicle lamp optical element (1), which diversifies the functions of the vehicle lamp optical element (1).
