Abstract
The invention relates to a lamp-reflector unit () provided with a first () and a second light source () axially disposed on a lamp axis (), and a reflector () with a reflecting part (). A modification of the reflecting part of the reflector to a shape somewhere in between a parabolic shape and a shape of a straight cone achieves that light of a narrow beam, i.e. a beam with a beam angle less than 15°, is obtained from the first light source, while the light beam as obtained from the second light source does not show any 'optical hole' in its center.
