Lighting unit and vehicle headlamp

A lighting unit (1) is provided with a reflecting surface (2, 2′, 2″) for providing an output beam of light with at least two beam patterns. A first light source (5) and a second light source (7) are arranged to illuminate substantially identical surface areas of said reflecting surface (2, 2′, 2″)...

Beschreibung
Zusammenfassung:	A lighting unit (1) is provided with a reflecting surface (2, 2′, 2″) for providing an output beam of light with at least two beam patterns. A first light source (5) and a second light source (7) are arranged to illuminate substantially identical surface areas of said reflecting surface (2, 2′, 2″) and are independently controllable from each other. The reflecting surface (2, 2′, 2″) is shaped and said light sources (5, 7) are positioned relative to said reflecting surface (2, 2′, 2″) so that said first light source (5) generates an output beam of light, having a first beam pattern and said at least second light source (7) generates an output beam of light, having a second beam pattern, different from said first beam pattern. A corresponding vehicle headlamp (10) comprises at least one lighting unit (1).
