Beschreibung
Zusammenfassung:The general field of the invention is that of lighting devices compatible with the use of night vision binoculars, said lighting device (1) comprising: a row of first light-emitting diodes (11) carried and powered by an electronic circuit (12), a mechanical part (13) on which the electronic circuit is attached; a second light-emitting diode (14) surmounted by an optical filter (15), said optical filter having spectral transmission such that the light from the second diode filtered by said filter is compatible with the use of said night vision binoculars. In the lighting device according to the invention, the mechanical part comprises at least one hollow housing (16) in which the second filtered light-emitting diode is attached, the depth of the housing being sufficient for the top part of the optical filter not to protrude beyond the top part of the first light-emitting diodes. Le domaine général de l'invention est celui des dispositifs d'éclairage compatibles de l'utilisation des jumelles de vision de nuit, ledit dispositif d'éclairage (1) comportant : une rangée de premières diodes électroluminescentes (11) portées et alimentées par un circuit électronique (12), une pièce mécanique (13) sur laquelle est fixé le circuit électronique; une seconde diode électroluminescente (14) surmontée d'un filtre optique (15), ledit filtre optique ayant une transmission spectrale telle que la lumière issue de la seconde diode filtrée par ledit filtre soit compatible de l'utilisation desdites jumelles de vision de nuit. Dans le dispositif d'éclairage selon l'invention, la pièce mécanique comporte au moins un logement creux (16) dans lequel est fixée la seconde diode électroluminescente filtrée, la profondeur du logement étant suffisante pour que la partie supérieure du filtre optique ne dépasse la partie supérieure des premières diodes électroluminescentes.
