Definitions

  • the invention relates to a reflector or a lamp according to the preamble of claim 1 or 2.
  • a reflector of this kind it is the purpose of a reflector of this kind to reflect as much as possible of the portion of the light that emits a lamp into the space to be illuminated. Since conventional lamps radiate the light essentially on all sides, this applies to the area of the lamp, which does not face the room directly. To remove the light from the lamp in its remaining area, i. In their area facing away from the space to be able to reflect radiated light, known reflectors have a dome-shaped cross-sectional shape, wherein an associated socket is arranged in such a position that a lamp seated therein in the cavity, in particular in the upper region of this cavity, is arranged.
  • the design of the reflector in its ridge region is problematic for several reasons. This is partly due to the lamp itself or its version, because it requires an opening in the ridge region of the reflector in order to mount or dismount the reflector at a built-in lamp of the radiating aperture of the lamp or the lamp after installation of the Reflector to connect with the socket. To ensure this, it is customary to ensure a recess of such a size in the ridge region of the reflector that either the reflector with the recess can be moved over the lamp or the lamp can be connected to the socket through the recess. Although this recess allows the assembly, but they are the reflection surface of the reflector and thereby reduces the utilization of the radiated light of the lamp. Another disadvantage of this known embodiment is that the opening in the ridge area of the room to be illuminated is visible as a dark spot, which should be avoided.

  • the reflector can be adjusted transversely to the central axis of the passage opening at least in its upper edge region of its reflector wall and adapted to different requirements.
  • a request may e.g. be temporarily to create a free space in the ridge region of the reflector wall in order to mount or dismount the reflector from the transmission opening and thereby move the reflector with the outwardly adjusted edge region of the lamp and then in a lamp engaging behind the position, to reduce the free space and increase the reflection area.
