  • the invention relates to a lighting unit which can be inserted into a wall or ceiling opening and consists of a housing with a front light exit surface and a rear surface.
  • a lighting unit of the type mentioned is known from practice. Such lighting units are used, for example, to generate light in a showcase, in order to illuminate, in particular to backlight, objects arranged in the showcase.
  • a disadvantage of such arrangements is that both heat and ultraviolet radiation arise within the opening due to the properties of the illuminant, which adversely affects both the object to be illuminated and the climate inside the showcase or opening.
  • the assembly of the lighting unit inside the opening is complex.
  • the object of the invention is to improve a lighting unit of the type mentioned at the outset such that unwanted radiation is reduced on the one hand and installation in the opening is facilitated on the other hand.
  • the use of light-emitting diodes as the illuminant results in a significant reduction in ultraviolet radiation or heat within the opening.
  • the modular construction of the housing results in easy assembly and disassembly, since the entire housing unit only has to be connected to the stationary power supply via the rear connection device and further installation work is not required.
  • a particularly preferred embodiment provides that a plurality of separately controllable light-emitting diode triples of the colors red-green-blue are provided, so that by using the separately controllable light-emitting diode triplets, an arbitrarily predefinable additive color mixture can take place, so that both white light and colored light can be obtained Can generate light of any wavelength and time sequence.
  • the housing of the lighting unit is an integral part of a box that can be inserted into the wall or ceiling opening in order to further improve the modular structure and the associated ease of assembly and disassembly. This practically results in a plug-in product for the backlighting of surfaces arranged in the opening Objects.

  • the LEDs are controlled by means of known current sources. Due to the separate controllability of the triple LEDs, an appropriately designed control electronics can be used to achieve additive color mixing. This results in the desired optical effects. For example, white light can be generated from the three light-emitting diode colors by an appropriate color mixture. However, there is also the possibility of achieving light of any wavelength and according to the desired intensity through the design of the control electronics.
  • the invention described above is preferably suitable for producing a showcase module in which the object to be backlit can be arranged in a niche or a showcase in a wall or ceiling opening and backlit with the desired color effects.

Abstract

L'invention concerne une unité d'éclairage insérable dans une ouverture de paroi ou de plafond, comprenant un boîtier (1) avec une face de sortie de lumière (2) située à l'avant et une face arrière. L'invention vise à perfectionner une unité d'éclairage du type précité, de manière à permettre d'une part une diminution de rayons indésirables et d'autre part, de faciliter le montage dans l'ouverture. A cet effet, il est prévu selon l'invention que la face arrière (3) porte un dispositif de raccordement (4) coopérant avec l'alimentation en courant électrique dans l'ouverture et prévu pour l'alimentation électrique d'une unité électronique de commande (5) disposée sur le boîtier ou dedans. Cette unité électronique de commande se présente de manière à piloter des groupes de diodes électroluminescentes (6) qui servent de moyens lumineux et sont disposés dans un plan parallèle à la face de sortie de lumière (2).
