摘要： An electric lamp arrangement includes a reflector (10) having first and second mirror walls (12 and 22), which in axial sections are curved according to circular arcs (13, 23), the centers of which lie in an area between lines (15, 16) enclosing angles .beta. and .gamma. with a plane P defining the largest diameter (d), and in an ellipse-shaped area Q, respectively. The reflector has a relatively small, light-emitting window (30) of at most 0.7 d, disposed opposite a lamp base (1). An electric light source (3) is disposed within the reflector (10) near plane P and an axis (11). The reflector (10) may be integral with a lamp vessel (5) to give a reflector lamp or a pressed-glass lamp. Alternatively, the light source may have an envelope and may be secured within the reflector to constitute a lamp-reflector unit. The reflector effectively shapes radiation emitted by the light source into a wide beam of high intensity. Embodiments provide an equal illumination of a large area by means of several light sources arranged beside each other. Other embodiments provide a homogeneous illumination of a relatively large area.

摘要： The electric incandescent lamp according to the invention has a lamp vessel (1) comprising a second wall portion (6) opposite to a neck-shaped first wall portion (4). Between the largest diameter (3) and the second wall portion (6) is disposed a third mirror-coated wall portion (7,7'), which is mainly curved in axial section along the arc of a circle, whose center (8,8') is located on the other side of the axis of symmetry (2) and of a plane passing through the largest diameter (3). The filament (10) has a plane of symmetry passing through the axis of symmetry (2) and extends on either side of a second plane through said axis at right angles to the first plane. The lamp produces together with an external reflector a narrow beam with a high luminous flux at the center thereof.
