Definitions

  • the present invention relates to an arrangement for emitting light with an LED module and associated optical devices.
  • a positioning line 5 is provided for this purpose, on each of which a certain number of LEDs 3 are placed.
  • the electrical connection of the LED module 2 is not shown for reasons of clarity.
  • the carrier 7 is essentially preferably flat.
  • a further embodiment of an LED module 8 is shown, consisting of a carrier 9 in an elongated, rectangular and planar embodiment and an array of LEDs 10, consisting of two rows of twenty LEDs 10.
  • the design of the carrier 9 is of course not only this form is limited.
  • the LED module 8 has an axis of symmetry in the longitudinal direction.
  • electrical contacts 11 for the power supply of the LED module 8 are shown.
  • the density of the LEDs 10 in an outer region of the carrier 9 is higher than in a middle region in order to more evenly distribute the thermal load of the carrier 9 during operation, taking into account the more efficient heat conduction in the edge region of the board.
  • the light-emitting devices 1 and 13 can be combined with one another in any desired manner. This is of course to be understood in the context of technical feasibility and advantage or usefulness. The focus is finally on the thermally optimized design of optical systems.

Claims (5)

  1. Dispositif d'émission de lumière (1) constitué
    - d'un module LED (2), constitué d'une disposition de LED (3) branchées de manière électronique et d'un support (7) pour les LED,
    la disposition des LED (3) étant choisie de façon à ce que la sollicitation thermique du support (7), provoquée par le fonctionnement des LED (3), est répartie globalement uniformément sur le support (7) et
    - d'un dispositif optique,
    le dispositif optique étant un système à trame cellulaire (4) constitué de cellules individuelles (6) en forme de cuvettes, dans lesquelles les LED (3) sont disposées,
    la disposition des cellules individuelles (6) étant homogène ou présentant une trame uniforme et le nombre de LED (3) étant différent d'une cellule individuelle (6) à l'autre,
    la densité des LED (3) étant plus importante dans une zone externe ou une zone de bord du support (7) que dans une zone interne ou centrale.
  2. Dispositif selon la revendication 1,
    caractérisé en ce que
    dans chaque cellule individuelle (6), est disposée au moins une LED (3).
  3. Dispositif selon la revendication 1 ou 2,
    caractérisé en ce que
    chaque cellule individuelle (6) définit plusieurs possibilités de positionnement fixes qui permettent un positionnement flexible des LED (3), par exemple à l'aide d'une ligne de positionnement (5).
  4. Dispositif selon l'une des revendications précédentes,
    caractérisé en ce que
    toutes les LED (3) sur le support (7) sont globalement identiques.
  5. Dispositif selon l'une des revendications précédentes,
    caractérisé en ce que
    toutes les LED (3) sont disposées dans un plan.
