Definitions

  • the present invention relates to a lighting device with a preferably flat-shaped support structure to which a plurality of crystals are fixed, which emit light rays in the space to be illuminated when irradiated by a light source.
  • Crystals attached to a support structure are already known in the form of so-called crystal curtains, which are used as room dividers and are illuminated with an illumination source, so that the crystals reflect the light and emerge shining.
  • the crystals are strung here in the manner of a glass pearl necklace on thin, almost invisible threads, so that a crystal curtain is created by a multitude of juxtaposed threads.
  • crystal means and in the context of the present invention not necessarily in the physical sense crystalline-trained body, but may also mean amorphous trained body, which are shaped only in the manner of rock crystals.
  • crystals in the context of the present invention may also comprise crystal glass bodies or consist of transparent, optionally colored glass, which may contain metal oxides or ions as additives.
  • such glass may consist of lead oxide, barium oxide, potassium oxide or zinc oxide or contain it to a substantial extent.
  • the crystals serve more for the optical decoration than the illumination of the space in front of the crystal curtain, which is not appreciably illuminated by the crystals.
  • the crystals do not produce ordered illumination with sufficiently high illuminance levels in vertical planes and do not fulfill a significant room illumination function, but are merely decorations.
  • the crystals have blind-hole-shaped recesses, in each of which a light-emitting diode is arranged in order to make the crystal shine from the inside.
  • this training is disadvantageous in several respects.
  • the crystals are made very large in order to record at all sources of illumination inside, so that the crystals only decorating purposes and no dynamic light situation can be generated, which makes the crystals sparkle for passing people actually in the sense of a crystal wall.
  • the decorative crystals of this document are very wide compared to their height, so that no high packing density of the body is achieved and, accordingly, a fairly static appearance.
  • the energy supply of the light sources inside the crystals is very complex, and this also limits the variability of the arrangement of the crystals, since the power must always be from behind, which in turn impairs the formation of the crystal backs.
  • the font DE 30 27 400 describes a ceiling panel in which pyramidal reflector contours are embossed in order to illuminate horizontal work surfaces such as a table largely shading from above can. This prior art lighting device thus does not provide high vertical illuminance levels.
  • the present invention seeks to provide an improved lighting device of the type mentioned above, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner.
  • the irradiated crystals in the room to be illuminated should produce a sufficiently high level of vertical illuminance without dazzling persons in the room, and achieve clear room illumination with brilliant light with a sparkling ambience for moving viewers.
  • the crystals In order to radiate brilliant light of sufficiently high luminances from the crystals into the space to be illuminated, it is proposed to arrange at least one light source for irradiating the crystals at a distance from the crystals and to separate the crystals from one crystal outside at an acute angle to the surface. in which the crystals are arranged to irradiate and form the crystals deposited on the support structure back reflective, so that the light is thrown targeted in the room to be illuminated.
  • At least one light source for irradiating the crystals is arranged at a distance from the crystals such that the crystals are irradiated from one crystal outside at an acute angle to the surface in which the crystals are arranged, the crystals each facing away from the space to be illuminated Rear side are provided with a reflective surface coating.
  • the one-sided surface coating of the crystals in combination with the acute-angled light supply from the outside prevents the light from the crystals in ineffective directions for the room lighting, so that the light with which the crystals are irradiated, is thrown most efficiently in the room to be illuminated and the Crystals act as punctiform light sources.
  • the irradiation of the crystals from the outside makes it possible for a light source to operate or illuminate a plurality of crystals.
  • the light source may be spatially separated from the crystals, in particular spaced, resulting in greater freedom for the design of the crystals, but also for the arrangement of the light source.
  • the refraction can occur in the medial transition, where the light can hit the back of the crystal, be directed and exit on the front.
  • the arrangement may be such that the light exits again on the side of the crystal on which it has previously entered.
  • This approach is based on the idea that high vertical illuminance with horizontal beams, without dazzling the people looking in that direction, can be achieved inter alia by using very high luminance (L> 10 million cd / m 2 ) in a very small solid angle range (solid angle ⁇ ⁇ 0.05 steradian, preferably even less than 0.01 steradian) in such a way that the observer perceives a changing, dynamic glittering point field with slight spatial movements (eg changing the head position). If the eye moves relative to the curtain, then the individual crystal dots flash alternately briefly. In order to prevent dazzling, disturbance or impairment of the visual performance of this frontal horizontal radiation, it is provided that these glittering spots or crystals do not exceed a certain size and have a certain minimum distance. In addition, this dynamic ('flash') is achieved by this narrow radiation of the individual light points or crystals for the moving observer.
  • the same effect would not be achieved, but rather a strong increase in the scattered light would create a diffuse atmosphere and the glare effect would be increased.
  • the reflective surface coating on the back of the crystals allows the crystals to shine in one direction, so that not only the lighting effect itself and the brightness achieved in the room is significantly increased, but in the illuminated room people the impression of the sparkling of the crystals around Multiple is increased. In this case, the lighting situation is given a high degree of dynamics, since a person moving in the illuminated space repeatedly encounters light flashes from other crystals with even slight movement relative to the crystal structure, so that the sparkling of the crystals moves dynamically across the surface of the crystal wall.
  • the crystals are aligned with their major axes at least approximately uniform or parallel to each other, in particular such that the crystals all radiate predominantly in the space to be illuminated.
  • the said crystals each have a major axis which extends substantially perpendicular to the plane in which the respective crystal has its maximum circumference and / or maximum diameter.

  • the crystals may be aligned with said major axes lying parallel to each other and perpendicular to the plane to be illuminated, in which the desired high vertical light intensities are to be achieved.
  • the crystals are advantageously twisted relative to one another or arranged with different angles of rotation.
  • the crystals have facet faces which are oriented towards different directions by twisting the crystals, in particular around the aforementioned major axis, i. If various crystals are converted into one another by displacement, the facet surfaces do not coincide with each other due to the twisted arrangement of the crystals. For example, if a first crystal with its facet face oriented upwards is exactly aligned in the direction of 12 o'clock, a second crystal with its facet face directed upward is aligned at 1 o'clock, while a third crystal with its face facet face is directed after 11 o'clock ,

  • both the front side and the back side of the crystals are provided with a facet contour, wherein the facet surfaces on the rear side are preferably inclined at a shallower angle to the base surface of the facet contour than the facet surfaces on the front side of the crystals.

  • the facet surfaces of the front side may be inclined at an angle of 20 ° -60 °, preferably 25 ° -50 ° and in particular about 30 ° -45 ° to the base surface of the faceted contour.
