Definitions

  • the invention relates to a lighting unit with at least one light source and with a substantially plate-shaped, transparent construction element, in particular a glass pane.
  • Glass showcases are particularly suitable for this purpose, as they allow a viewing of the presented object from several sides and the perfect surface of the glass structural elements used, be it vertically oriented side walls or floors, together with the presented object create an appealing overall picture.
  • the presented object lamps are preferably used, which are arranged on the display case itself, so as to be able to illuminate the presented object from a short distance and thus high light intensity.
  • the bulbs themselves occupy only a small volume of construction, so that they do not partially obstruct the view of the object or by their existence partially distract from the presented objects. Furthermore, avoid that a part of the light in the direction of The viewer is guided and thus distracts from the presented objects.
  • Halogen reflector lamps which produce a bright light, are therefore unsuitable for direct mounting on the showcase in many cases.
  • the high proportion of heat in the radiation of incandescent lamps can permanently damage sensitive objects, such as works of art or perfume bottles.
  • LEDs are due to their small size particularly suitable for direct mounting on showcases or showcases.
  • light-emitting diodes are characterized by a high light yield, high available light output with steadily decreasing prices, and by a light spectrum coming closer and closer to the natural white light. They are therefore increasingly used for lighting purposes in showcases, shop fitting or in the presentation of furniture, for the reasons mentioned above usually a combination with glass is chosen.
  • a first known solution facing the viewer edge surface of a glass with a the edge surface covering sheet metal profile, which in turn protrudes beyond the edge surface provided.
  • a number of light-emitting diodes are arranged in the projecting beyond the edge surface portion of the sheet metal profile, illuminate the items placed in the showcase, but are hidden from the viewer's direction by the sheet metal profile.
  • the problem here is on the one hand, that the light emitting diode is offset from the edge surface of the glass, which widens the edges of the glass pane in an optically unfavorable manner and partially restricts the viewer's view of the illuminated object.
  • the diodes are exposed to pollution unprotected.
  • a glass pane installed in a showcase has a beveled edge surface facing the viewer, which is adjoined by another elongated, beam-like glass element with a likewise beveled side surface.
  • a plurality of light-emitting diodes are arranged, which illuminate the object stored in the showcase obliquely from the front as seen by the observer. Since the light-emitting diodes are arranged on a glass component, they are visible from the direction of the viewer, which is disadvantageous for aesthetic reasons. To avoid visibility, although non-transparent or partially transparent glasses, in which case the additional glass element restricts the view of the illuminated object and the exposed LEDs are exposed to contamination as in the first solution.
  • the present invention seeks to provide a lighting unit with at least one lamp and a substantially plate-shaped, transparent construction element, in particular a glass, which allows effective and effective lighting of objects and goods from the viewer's perspective, the used Bulb should be largely protected from contamination and attaches the bulb to the structural element without affecting the aesthetics of the structural element.

  • ESG Single-pane safety glass
  • transparent construction elements with a slightly different surface from a completely flat surface are understood as construction elements in the context of the invention, as far as the material of the construction element for the light emitted by the light source is transparent. A strict parallelism is not crucial here.
  • the free space is formed by a provided in the edge surface of the structural element bevel surface.
  • a chamfer surface is here considered a surface which is formed at an acute angle to the actual surface of the structural element in this in the edge region of the plate-shaped construction element. This does not necessarily have to be an area subsequently formed in the construction element.
  • the free space may also be formed by a molded-in in the edge surface stage.
  • the particular advantage of a chamfer surface lies in the fact that it can be incorporated into an edge surface comparatively easily and with machines usually present in the glass-working industry.

With the relative positioning of the luminous means to the chamfer surface of the constructional element, the angle of incidence of the intensity maximum of the light emitted by the luminous means into the chamfer surface is set.
  • the light emitted by the light source is radiated perpendicular to the chamfer surface and this has approximately an angle of 28 ° relative to the surfaces of the plate-shaped construction element, so the light occurs on the chamfer surface opposite the plate surface of the structural element at an angle of approximately 45 ° to the surface of the construction element, so that if the construction element is a glass side wall or a glass bottom of a showcase, the one to be illuminated Object can be placed in the middle of such a showcase in the usual way and is optimally illuminated.
