摘要:
The invention relates to a lighting device for a motor vehicle headlamp, comprising a primary optical element (100) which is arranged in the main beam direction of a first light fixture (50) and which has a light coupling-in surface (110) for coupling in light into the primary optical element (100), a light coupling-out surface (120) as well as a lateral surface which extends between the light coupling-in surface (110) and the light coupling-out surface (120) and on which the light coupled in can be relayed by total reflection in the direction of the light coupling-out surface (120) of the primary optical element (100), a secondary optical element (200) which is arranged after the light coupling-out surface (120) of the primary optical element (100) and which has a light coupling-in surface (210) and a light coupling-out surface (220), and an arranged reflector (400, 410, 420), the secondary optical element (200, 250, 500) being designed as part of a quadric, the secondary optical element (200, 250, 500) being configured to guide the light beams on the reflector (400, 410, 420) 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 (50) and reach the light coupling-out surface (220, 270, 520) of the secondary optical element (200, 250, 500).
