Title (EN) LIGHT SHIELD USING INTEGRATED LIGHTING TO CREATE OPACITY AND PRIVACY IN WINDOWS
(FR) ÉCRAN LUMINEUX METTANT EN ŒUVRE UN ÉCLAIRAGE INTÉGRÉ POUR ASSURER L'OPACITÉ DES FENÊTRES ET LA PROTECTION DE L'INTIMITÉ
Abstract:
(EN) The invention provides a privacy window system (1) comprising a window panel (100), a lighting unit (200), and a control unit (300), wherein (i) the window panel (100) comprises a first surface (110), a second surface (120) and an edge (130), wherein the window panel (100) is transmissive for visible light wherein at least one of the surfaces (110,120) of the window panel (100) comprises surface structures (105), configured to generate visible privacy light (101) under irradiation with lighting unit radiation (201); (ii) instead of using edge-lighting for the irradiation of the window panel (100), the lighting unit (200) is configured to irradiate one of the surfaces (110,120) of the window panel (100) with said lighting unit radiation (201) thereby inducing said privacy light (101) and reducing visibility through the window panel (100) in at least one direction; and (iii) the control unit (300) is configured to control the lighting unit radiation (201) as function of an input signal.
(FR) L'invention concerne un système de fenêtre protégeant l'intimité (1) comprenant un vitrage (100), une unité d'éclairage (200), et une unité de commande (300). Ledit système de fenêtre est caractérisé en ce que : (i) le vitrage (100) comprend une première surface (110), une seconde surface (120) et un bord (130), ledit vitrage (100) transmettant la lumière visible, au moins une des surfaces (110, 120) du vitrage (100) comprenant des structures de surface (105) configurées pour générer une lumière visible de protection de l'intimité (101) sous l'effet de l'irradiation par rayonnement (201) de l'unité d'éclairage; (ii) au lieu d'utiliser un éclairage de bord pour l'irradiation du vitrage (100), l'unité d'éclairage (200) est configurée pour irradier une des surfaces (110, 120) du vitrage (100) au moyen dudit rayonnement (201) de l'unité d'éclairage, ce qui permet de générer ladite lumière de protection de l'intimité (101) et de réduire la visibilité à travers le vitrage (100) dans au moins une direction; et (iii) l'unité de commande (300) est configurée pour commander le rayonnement (201) de l'unité d'éclairage (201) en fonction d'un signal d'entrée.
