Abstract

MODULE LUMINEUX AVEC IMAGEUR A FIXATION AMORTISSANTE ET CHAUFFANTE L’invention a pour objet un module lumineux (6) notamment pour véhicule automobile, comprenant un imageur (8) avec une face avant (8.1), une face arrière (8.2) et un bord périphérique (8.3) ; un dispositif de rétroéclairage (10) de l’imageur (8), disposé en vis-à-vis de la face arrière (8.2) dudit imageur ; un support (12) avec une zone de réception (12.3, 12.4) de l’imageur (8) et une zone de fixation (12.2) du dispositif de rétroéclairage (10) ;caractérisé en ce que le module lumineux comprend, en outre, au moins une bande en matériau souple et chauffant électriquement (16) en contact avec le bord périphérique (8.3) de l’imageur (8) et la zone de réception (12.3, 12.4) dudit imageur sur le support (12). L’invention a également pour objet un procédé de contrôle de température de l’imageur (8) du module lumineux. (Figure à publier avec l'abrégé : Figure 1)LIGHT MODULE WITH IMAGER WITH DAMPING AND HEATING FIXING The invention relates to a light module (6) in particular for a motor vehicle, comprising an imager (8) with a front face (8.1), a rear face (8.2) and a peripheral edge (8.3); a backlighting device (10) of the imager (8), arranged opposite the rear face (8.2) of said imager; a support (12) with a receiving area (12.3, 12.4) of the imager (8) and a fixing area (12.2) of the backlighting device (10); characterized in that the light module further comprises, at least one strip of flexible and electrically heating material (16) in contact with the peripheral edge (8.3) of the imager (8) and the reception zone (12.3, 12.4) of said imager on the support (12). The invention also relates to a method for controlling the temperature of the imager (8) of the light module. (Figure to be published with the abstract: Figure 1)
