Abstract
The invention relates to a lighting device for a motor vehicle headlamp, comprising a primary optical element () which is arranged in the main beam direction of a first light fixture () and which has a light coupling-in surface () for coupling in light into the primary optical element (), a light coupling-out surface () as well as a lateral surface which extends between the light coupling-in surface () and the light coupling-out surface () and on which the light coupled in can be relayed by total reflection in the direction of the light coupling-out surface () of the primary optical element (), a secondary optical element () which is arranged after the light coupling-out surface () of the primary optical element () and which has a light coupling-in surface () and a light coupling-out surface (), and an arranged reflector (), the secondary optical element () being designed as part of a quadric, the secondary optical element () being configured to guide the light beams on the reflector () by means of refraction or let the light beams pass without a change of direction during coupling, which light beams are emitted by the first light fixture () and reach the light coupling-out surface () of the secondary optical element ().
