Title:
OPTICAL ELEMENT AND COR RESPOND I NG VEHICLE LAMP AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/187307
Kind Code:
A1
Abstract:
An optical element(100) comprises: a light entry surface (150); a first reflective surface (130) and a second reflective surface (140); a light exit surface (120); and at least one connecting surface (110), located between the first reflective surface (130) and/or the second reflective surface (140) on the one hand and the light exit surface (120) on the other, wherein the connecting surface (110)at least partly comprises an enhanced reflection part (1101) for expanding a maximum exit angle of emergent light exiting via the light exit surface (120). There is no need to process a surface at the light exit surface (120), so the range of applicability of the optical element (100) is increased; moreover, the optical element (100) has a greater distance between the light exit surface (120) and light entry surface (150). The optical element (100) can adapt to a greater variety of shapes.
