  • the customer first selects the size of the desired luminaire, for example a luminaire size that has a 3 x 3 grid as in Fig. 1 enables.
  • Other sizes of the lamp can also be made available for selection, for example several function fields in a row, or a grid of function fields in the manner of a 2 x 2 or 3 x 2 grid.
  • the customer then configures the functional fields 13, in other words, he selects which light effect or which light distribution the functional field 13 is to produce. If a sensor is to be built in, the customer also chooses this.

  • the control of the LED devices 17 of the functional fields 13 of the luminaire 1 can be implemented in a simplified manner. While the embodiment described above is highly flexible and very versatile in the possible lighting effects, the luminaire 1 can be constructed without the central control arrangement 25 in a simplified embodiment, for example if simpler lighting effects and lower costs are desired. While the mechanical, optical and thermal concept explained for the exemplary embodiment described above remains unchanged, in the simplified variant the supply of the LED devices 7 takes place via an external converter 30 which can be arranged in the connecting line 90, for example. See the schematic in Fig. 19 .
  • the converter 30 can be a DALI converter with one or two output channels, whereby a more cost-effective control with reduced complexity is provided for simpler applications.
  • all of the functional fields 13 could be designed, for example, as downlights or wallwashers, but a combined arrangement of downlights and wallwashers is also possible in the simplified variant described above with control via the external converter 30.
  • connection and control unit 17 of the embodiment described above in the simplified variant now forms a connection unit 17 which z. B. only has a strain relief for the connection line 90 and plug connections for connecting the LED carrier boards 6 via flexible cables.
  • a reduced number of channels could be provided, for example for simpler applications in which several individually controllable light effects are to be combined in the luminaire 1.
  • the number of control channels could be less than nine, for example four or eight.
  • the luminaire 1 thus makes it possible to display different lighting effects and different light scenes as well as to illuminate a large area of space while at the same time making the luminaire 1 very compact. This is achieved without a mechanical adjustment of individual light sources being provided.
  • a flexible and modular coupling of different numbers of LED carrier boards 6 is possible.
  • the housing component 2 is also optimized with regard to the dissipation of heat and enables efficient cooling of the LED devices 7.
  • the luminaire 1 has a low height and thus also a comparatively small space requirement.
  • the voltage supply and the control of the LED devices 7 succeed in a space-saving manner.
