Optical element for lighting device of vehicle, has body, which is formed of transparent material in one-piece and has multiple bounding surfaces

摘要

The optical element (1) has a body (10), which is formed of transparent material in one-piece and has multiple bounding surfaces. The bounding surfaces of the body are formed by a light-coupling bounding surface (11), a reflective hyperbolic bounding surface (12), an additional reflective bounding surface (13) and a light-uncoupling bounding surface (14).
