Definitions

  • the invention relates to a reflector lamp according to the preamble of claim 1.
  • a reflector lamp is in terms of their general photometric properties, for example, in the "Handbuch für Illumination ", 4th ed., Verlag W. Girardet, Essen (see page 107 there) and described in the generic DE-U1-200 19 334. Characteristic of such a luminaire with parabolic reflector is that parallel light exits the reflector when the light source is in focus located.
  • Reflector lights serving as ground lights have in the Usually a very flat parabolic reflector, but this has the consequence that such a reflector lamp significantly fades when viewed from above.
  • glare can be prevented by shielding the light source by means of a Calotte, which gives a direct insight e.g. on the lamp filament prevented.
  • the invention is the Task based, in particular a floor, ceiling or recessed wall reflector light to create which a compact, especially flat design and which in spite of their flat design a substantially glare-free lighting allowed.

  • the invention has an axially shortened design of the Parabolic reflectors allowed. Due to the fact that the parabolic reflector in essential only between his head and one through the focal point placed, the axis of symmetry of the parabolic reflector perpendicular intersecting Lichtaustrittsebene is light-conducting effect, the parabolic reflector can either around the outside of the light exit plane located lighting technically ineffective Reflector area shortened or the ineffective outer reflector area for design purposes, for example, a appealing transition to the luminaire housing to create.
  • the invention Due to the fact that the electric light source or the electric light source in the light exit plane with respect to the focal point translationally displaceable or is arranged translationally shifted, the invention has the Possibility to divert the exiting parallel rays of light so that they are not axially parallel to the axis of symmetry of the parabolic reflector but at a tilt angle to the symmetry axis of the parabolic reflector can escape from this.
  • Reflector luminaire can be used to flat surfaces, e.g. Streets, squares, Entrances etc. to illuminate largely glare-free. So it is e.g. possible, in Entrances reflector lamps according to the invention, in particular recessed wall lights, whose light exit plane extends vertically, about in the headlight height of motor vehicles to illuminate the track so that the driver is not dazzled even if the lamp is directly in the Viewpoint of the driver is located.
