Abstract: This invention relates to a lamp-reflector unit (3) provided with a first (15) and a second filament (17) axially disposed on a lamp axis (1), and a circularly symmetrical reflector (7) with a reflecting part (13). The use of a modified low-voltage H4 automotive halogen lamp leads to a relatively cheap lamp-reflector unit for application in shop and home lighting enabling direct switching from spot-lighting to flood-lighting.

Abstract: The invention relates to a lamp-reflector unit (3) provided with a first (15) and a second light source (17) axially disposed on a lamp axis (1), and a reflector (7) with a reflecting part (13). 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.

Abstract: The invention relates to a lighting unit (1) having a concave reflector (2) with an axis of symmetry (3) and a light emission window (21) bounded by a circumferential edge (20) transverse to the axis, an elongate light source (30) extending substantially along the axis of symmetry (3), which light source (30) is accommodated in a holder (4) opposite the light emission window (21), and a cup-shaped axially positioned cap (5), which cap partly surrounds the light source and forms an optical screening means to intercept unreflected light rays. According to the invention, the cap (5) is surrounded at a distance d by a screening ring (50), which extends over a height h in the direction of the light emission window (21).
