Definitions

  • the invention relates to a specially designed lighting device for generating aesthetic-artistic lighting effects, preferably in closed rooms.
  • a light diaphragm designed as a cylindrical section can be arranged between the lens and the lens in a radius to the longitudinal axis of the rod-shaped light source, and the rod-shaped light source can also be horizontal with its longitudinal axis and horizontal with respect to the central axis.
  • the light source, the reflector and the lens can be arranged in a protective housing, in the end face of which the lens is embedded.
  • the reflector designed as a cylinder section consists of a number of individual, flat mirrors in the form of rectangular elongated strips which are aligned with the longitudinal axis of the rod-shaped light source.
  • the individual mirrors form an obtuse angle to each other, which can be 172.5 degrees.
  • the obtuse angles between the individual mirror strips can have angles which differ from one another.
  • a further modification can be seen in the fact that the widths of the successive mirror strips are different.
  • An additional embodiment of the invention also consists in that auxiliary mirrors are arranged on one or both sides of the reflector at a right or oblique angle to the longitudinal axis of the plane of the rod-shaped light source.
  • the arrangement can be such that the auxiliary mirror or mirrors either abut the reflector on one or both sides or are attached at a distance from the reflector.
  • the auxiliary mirror or mirrors are arranged on a mounting plate detachably fastened to the inner wall of the protective housing.
  • auxiliary mirrors by partially reflecting the light rays that are diffusely incident on the curved reflector onto the lateral auxiliary mirrors and reflecting them further in a large scattering angle range - overlapping with the reflected direct rays.
  • the arrangement according to the invention is accommodated in the protective housing 7, in the end face of which the lens 3 is seated. They are closed in the horizontal central axis x this light source 1 extending transversely in the y axis and the light diaphragm 4 arranged in front of it. This has a radius r to the longitudinal axis y of the light source 1.
  • the reflector 2 is also provided centrally to the central axis x, which consists of a cylinder jacket section 6 on which the individual mirror strips 5 of elongated rectangular shape are fastened.
  • the reflector 2 has a radius distance R from the light source 1, which is preferably 135 mm.
  • the width B of the reflector corresponds approximately to the length b of the light source 1.
  • the angle ⁇ between the adjacent mirrors 5 is preferably 175.5 °.
  • FIG. 3 and 4 show the arrangement acc. 1 and 2, but with side mirrors 8 arranged on both sides of the reflector 2.
  • the side mirrors are attached to the inner wall of the housing 7 at a distance a on both sides of the reflector 2.
  • the arrangement selected in the exemplary embodiment consists in each case of a mounting plate 9 which is detachably fastened to the wall 7 and on which the mirror 8 is attached. In this way it is possible to carry out the execution acc. Fig. 1 or 2 later retrofit according to Figs. 3 and 4.
