  • the profiled element 2 ' is embodied such that the free height bounded by the first flange section 2b' and the present angled flange section 2c 'is less than the thickness of the glass pane 3.
  • a non-positive connection ie a clamping connection, results between the profiled element 2 ', and the glass sheet 3, as this bends the profile element 2' when inserted into the profile element 2 '.
  • the profile element can be easily removed temporarily for maintenance and / or repair of the lighting device or 1.
  • the adhesive bond may be added to the adhesive bond (not shown).
  • the 8 and 9 relate to a lighting unit after the Fig. 3 in which the profiled element 2 is secured to the glass pane by means of end caps 2e, which are each pushed onto the glass element 3 oriented profile element 2, possibly additionally. Furthermore, the end caps serve to seal the volume between profile 2 and glass 3 frontally.
  • FIG. 10 A particularly advantageous modification of the lighting unit Fig. 3 is in Fig. 10 shown in a schematic cross-sectional view.
  • a strip of a light-scattering coating 3c extending parallel to the glass edge is provided on the lower plate surface 3b of the glass pane 3 extending parallel to the glass edge to produce a locally light-scattering surface.
  • the coating strip 3c has the function which is incident on the light exit surface 3b from the inside at an angle of incidence ⁇ , which in this case is greater than the critical angle ⁇ of the total reflection of the light irradiated by the LEDs 1 into the glass pane 3 at the light exit surface 3b from the glass pane 3 as scattered light, so that the portion of the light intensity reflected back into the glass pane 3 is minimized.
  • FIGS. 13 and 14 glass showcases or shop components are now shown in a schematic view, which with lighting units according to Fig. 3 are provided.
  • Fig. 13 is a shelf shown with three glass shelves, in which in each of the two upper shelves facing the viewer B outer edge 9 as a lighting unit according to Fig. 3 is trained.
  • the lighting unit thus irradiates the arranged on the underlying shelf in each case under a beam angle of about 45 ° and is not visible to the viewer B, while also does not hinder his field of view.
  • Fig. 14 are the glass side walls of a showcase at their respective the viewer B facing edge with a lighting unit according to Fig. 3 Mistake. These in turn irradiate the object placed in the display cabinet at an illumination angle of 45 °, without restricting the field of vision of the observer.
  • a glass canopy of a residential building with a lighting unit according to the invention is shown in side view.
  • the glass canopy is made of laminated safety glass Fig. 4 formed type and has a lighting unit according to Fig. 4 on.
  • a good illumination of the entrance area of the house is achieved at the same time appealing design of the canopy due to the discreet placement of the lighting unit in the outer edge of the canopy.
