Definitions

  • the invention relates to a profile element for a lamp, a lamp and a pendant lamp.
  • the object of the invention is to specify a profile element for a lamp, a lamp and a pendant lamp which is easy to produce and can produce a large number of lighting moods.
  • a profile element for a lamp is provided with a first concave area in cross section, which in use is open at the top or bottom, and a first concave area in cross section second concave area, wherein the first concave area has a first arrangement area for at least one first illuminant and the arrangement and shape are such that first light from the first illuminant is reflected upwards or downwards through surface areas of the first concave area.
  • the second concave area is designed to accommodate power supply and/or signal lines for the first illuminant.
  • the profile element can also be provided with a third concave area in cross-section, which is oriented differently than and preferably opposite to the first concave area, wherein the third concave area has a second arrangement area for at least one second light source and the arrangement and shape are such that second light from the second illuminant is reflected by surface portions of the third concave portion in a direction different and preferably opposite to that of the first light, and wherein the second concave portion is adapted to receive power and/or signal lines for the second illuminant.
  • the first and third concave areas may be superimposed when in use.
  • the second concave area can be between them.
  • At least parts of the surface of the first and possibly the third concave area can be designed as a reflecting or scattering light reflection surface for light from a lighting means and can have a locally planar or locally convex or concave surface area.
  • the profile element has a longitudinal direction and can have a constant cross-sectional shape in the longitudinal direction. In the longitudinal direction, it can be straight or curved. Lamps are located in the first and possibly in the third concave area.
  • the shape of the concave areas and relative thereto the arrangement of the lighting means and possibly the coating and surface treatment of the surface areas in the concave area are such that light from the lighting means is reflected out of the respective concave area.
  • the reflection can be specularly reflective or diffusely reflective. It can also be distributed over the cross section and/or over the length of the profile element Surface areas with different reflection properties can be provided, for example diffusely reflecting surface areas alternating with specularly reflecting surface areas.
  • the directions can be "up” and “down”, which can also include obliquely upwards and obliquely downwards, respectively.
  • Light emitted upwards runs towards the ceiling, from which it is again diffusely reflected and thus creates indirect, rather even room illumination.
  • Light emitted downwards can fall more or less directly onto a point to be illuminated, for example a table, and thus produce direct and then not necessarily uniform illumination.
  • the shaping of the first and/or the third concave region can be such that desired beam collection characteristics result.
  • a reflective surface of the profile element can be rectilinear in cross-section perpendicular to the longitudinal direction of the profile element, or concave as the entire area, or locally convex to produce desired beam collection or distribution properties.
  • the shapes in the first concave area can be different from those in the third concave area.
  • the second concave area can lie between the first and third concave area and can carry electrical lines for electrical energy and/or for signals that serve to supply energy and/or to control the lighting means.
  • the first concave area can be open at the bottom
  • the third concave area can be open at the top
  • the second concave area can lie between the two.
  • the lighting means in the different concave areas can be controlled independently of one another and then have supply lines that can be controlled independently of one another.
  • the profile element can have holding structures for a light-guiding element in the first and possibly third concave area.
  • light guide elements can be seated, which absorb light from the illuminant or from the reflecting surface, forward it in the interior and emit it via an exit surface.
  • These can be, for example, glass blocks or Plexiglas blocks, which in turn can be in the form of an elongate profile and can be shaped in such a way that they are designed to match or complement the shape of the profile element. In this way, the light can be directed and emitted in the desired manner.
  • the light entry surfaces and/or light exit surfaces of the light guide element can have straight and/or concave and/or convex areas in cross section perpendicular to the longitudinal direction. The shape of these surfaces can change over the length of the light-guiding element, or they can remain the same.
  • Parts of a light-guiding element that are visible from the outside can carry patterns in such a way that the surface finish is manipulated, for example in a way that they are diffusely processed according to the pattern. In this way, ornaments or inscriptions can be made.
  • the profile element can be constructed in one piece or have several individual profiles connected to one another. It can have one or more cast elements, in particular continuously cast elements, and/or one or more rolled elements, in particular an element with or made of a metal strip.

  • the profile element of the light guides the necessary cables on the one hand, and on the other hand holds the various light sources and also shapes the beam of the emitted light. Due to the different cables routed, the lamps can be controlled differently so that variable lighting moods can be created.
  • the profile element can have a metal strip on which two parallel strips running in the longitudinal direction form the first arrangement area and the second arrangement area, on each of which a plurality of first and second lamps, in particular light-emitting diodes, are arranged.
