Abstract

La présente invention concerne un dispositif lumineux (100) pour un véhicule automobile comprenant un boîtier (10), au moins une source lumineuse (12) configurée pour émettre un faisceau lumineux et une glace de fermeture (14) disposée sur le boîtier (10) configurée pour permettre à une quantité substantielle du faisceau lumineux émis par la source lumineuse de passer à travers la glace de fermeture (14). En outre, le dispositif lumineux (100) comprend au moins un film anti-condensation (20) prévu sur au moins une partie prédéterminée (16) d'une surface intérieure (14i) de la glace de fermeture (14). Au moins une partie prédéterminée (16) est une zone de la surface intérieure ayant une température de surface plus froide que le reste de la surface intérieure (14i). Le film anti-condensation (20) est configuré pour empêcher la formation de condensation sur la glace de fermeture (14) du dispositif lumineux (100). Figure pour l'abrégé : Figure 2]The present invention relates to a light device (100) for a motor vehicle comprising a housing (10), at least one light source (12) configured to emit a light beam and a closing glass (14) placed on the housing (10) configured to allow a substantial amount of the light beam emitted by the light source to pass through the cover glass (14). Furthermore, the luminous device (100) comprises at least one anti-condensation film (20) provided on at least a predetermined part (16) of an inner surface (14i) of the closing glass (14). At least a predetermined portion (16) is an area of the interior surface having a cooler surface temperature than the rest of the interior surface (14i). The anti-condensation film (20) is configured to prevent the formation of condensation on the closing glass (14) of the light device (100). Figure for abstract: Figure 2]
