Title
(EN) LIGHTING DEVICE WITH TRANSPARENT STABILIZER ELEMENT
(FR) DISPOSITIF D'ÉCLAIRAGE À ÉLÉMENT STABILISATEUR TRANSPARENT
Abstract
(EN)
The present disclosure relates to a lighting device (2) comprising light- emitting elements (4) such as light-emitting diodes arranged on a substrate (6). The object to provide a lighting device (2) comprising multiple light-emitting elements (4) and light guides (14), wherein the thermal sensitivity of the lighting device (2) is reduced in a particularly simple manner, is solved in that the lighting device (2) comprises: a lens (8) with a light entry side (10) and a light exit side (12); light guides (14), each light guide (14) being arranged in optical contact to at least one of the light-emitting elements (4) and being configured to guide light emitted by the at least one of the light-emitting elements (4) towards the light entry side (10) of the lens (8); and a transparent stabilizer element (16) being arranged in mechanical contact to the light exit side (12) of the lens (8), wherein the transparent stabilizer element (16) is configured to define the shape of the light exit side (12) of the lens (8) at least in regions. The invention further refers to a method for producing a lighting device (2).

La présente invention concerne un dispositif d'éclairage (2) comprenant des éléments électroluminescents (4) tels que des diodes électroluminescentes agencées sur un substrat (6). L'objectif de la présente invention est de fournir un dispositif d'éclairage (2) comprenant de multiples éléments électroluminescents (4) et des guides de lumière (14), la sensibilité thermique du dispositif d'éclairage (2) étant réduite de manière particulièrement simple, l'objectif étant atteint en ce que le dispositif d'éclairage (2) comprend : une lentille (8) présentant un côté d'entrée de lumière (10) et un côté de sortie de lumière (12) ; des guides de lumière (14), chaque guide de lumière (14) étant agencé en contact optique avec au moins l'un des éléments électroluminescents (4) et étant configuré pour guider la lumière émise par ledit élément électroluminescent (4) en direction du côté d'entrée de lumière (10) de la lentille (8) ; et un élément stabilisateur transparent (16) étant agencé en contact mécanique avec le côté de sortie de lumière (12) de la lentille (8), l'élément stabilisateur transparent (16) étant configuré pour définir la forme du côté de sortie de lumière (12) de la lentille (8) au moins dans des régions. L'invention concerne en outre un procédé de production d'un dispositif d'éclairage (2).
