LIGHT SHIELD USING INTEGRATED LIGHTING TO CREATE OPACITY AND PRIVACY IN WINDOWS

摘要

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.

主权项

1. A privacy window system comprising a window panel, a lighting unit, and a control unit, wherein:
the window panel comprises a first surface, a second surface and an edge, wherein the window panel is transmissive for visible light, wherein at least one of the surfaces of the window panel comprises surface structures, wherein the at least one of the surfaces comprising said surface structures is configured to generate visible privacy light under irradiation with lighting unit radiation; the lighting unit is configured to irradiate at least one of the surfaces of the window panel with said lighting unit radiation from a first and/or from a second second side thereby inducing said privacy light and reducing visibility through the window panel in at least one direction; and the control unit is configured to control the lighting unit radiation as function of an input signal.
