Abstract
A lighting device for a vehicle headlamp includes a plurality of light sources; a first lens element (FLE) downstream of the light sources; and a second lens element (SLE) downstream of the FLE. A light receiving surface (LRS) of the FLE is formed by a main-area and a sub-area. The light sources and LRS are distanced to each other whereby a first fraction of light is emitted towards the sub-area and a second fraction is emitted towards the main-area. The light sources, FLE, and SLE are configured to create a complete or partial, preferably adaptive, high beam light distribution with two sections. The sub-area and main-area are configured to refract impinging light, wherein refraction of light by the sub-area and main-area is such that a first intensity maximum of a first section is vertically lower in front of the lighting device than a second intensity maximum of the second section.
