Abstract (en)
The electric reflector lamp has a reflector body (1) with a reflecting surface (2) which is a body of revolution of a branch (7) of a parabola which has been tilted towards the optical axis (3) of the reflecting surface. The reflecting surface has superimposed plane axial lanes (6) of which the number in a first zone (9) remote from the light emission window (4) is half that in a second zone (10) adjacent said window. The axial lanes give the reflecting surface cross-sections which are regular polygons. A light source (13) is positioned on the optical axis, while the focus (8) is inside this light source. The lamp has a universal burning position, a good mixing of the generated light, and a comparatively high luminous flux in the beam. <MATH>
