Abstract
The present invention relates to a daylight deflection system including an arrangement of louvers () which are aligned and formed to block daylight impinging from an outer side () at higher angles of incidence with respect to a horizontal direction (), to deflect daylight impinging from the outer side () at lower angles of incidence with respect to the horizontal direction () towards an indoor ceiling, and to allow visual transmission in at least the horizontal direction (). In this deflection system OLED's () or optical light guides () coupled to LED's () are attached to or integrated in the louvers (), said OLED's () or light guides () being microstructured at a surface to deflect the daylight toward the indoor sealing. With this daylight deflection system indoor lighting combining daylight and artificial light is achieved in a compact manner.
