Definitions

  • the invention relates to a lighting system according to the preamble of independent claim 1.
  • Such lighting systems are used for example in pendant lights and can be used to illuminate goods in a sales, exhibition and / or trade fair room.
  • LED retrofits In connection with lighting systems or lighting equipment in general, retrofit means retrofitting modern lighting technology in an existing lamp or luminaire. When switching to economical LEDs, the old incandescent or halogen lamps can be replaced with appropriate LED retrofits.
  • the retrofit LED light sources have to fit into the respective socket of the existing lamp for easy conversion. For this reason, retrofit LEDs are manufactured and offered for practically all common lamp bases. For a successful replacement, the housing of the retrofit lamp should not be too large and there must be enough space in the lamp / luminaire used.
  • Retrofit lamps are now available for most common socket types.
  • the E27 retrofits are likely to be the most frequently used variant in Europe belong. These are usually provided with the conventional (Edison) light bulb shape.
  • the conventional retrofit LEDs for decorative pendant lights are easy to replace, but they are not very suitable for professional uses, since they regularly do not have sufficient light output and shadow lighting. This is then disadvantageously noticeable in applications in sales outlets or in fresh food and checkout areas, dressing rooms or cabins, information counters and vehicle deliveries, restaurant tables and food counters, lounges and bars as well as in reception areas and flexible office space.
  • the present invention is therefore based on the object of providing a lighting system which can be used in professional applications using conventional lampshades, for example in sales outlets or trade fairs. In addition, it should be ensured that wear and tear parts can be exchanged efficiently.

  • the term "designed for hanging” means in the present case in particular that the mounting device or the pendant lamp can be connected to a corresponding mounting device (usually a guide rail) in the ceiling area via an electric cable and by means of a suitable connecting part (e.g. a plug).
  • a suitable connecting part e.g. a plug.

In particular, such an exchange can take place independently of one of the optics unit, the mounting device and possibly a lampshade or a similar design element.
