Abstract:
The present invention relates to a daylight deflection system including an arrangement of louvers (5) which are aligned and formed to block daylight impinging from an outer side (3) at higher angles of incidence with respect to a horizontal direction (19), to deflect daylight impinging from the outer side (3) at lower angles of incidence with respect to the horizontal direction (19) towards an indoor ceiling, and to allow visual transmission in at least the horizontal direction (19). In this deflection system OLED´s (8) or optical light guides (16) coupled to LED´s (17) are attached to or integrated in the louvers (5), said OLED´s (8) or light guides (16) 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.

Abstract:
The invention relates to an electroluminescent device for emitting light having an adjustable color point. An electroluminescent region (1) emits light in response to a lighting current and a heating element (7) applies heat to the electroluminescent region (1). A heating control unit (9) controls the heating element (7) in applying the heat in order to adjust the color point of the emitted light. The color point of the light emitted by the electroluminescent device is dependent on the temperature of the electroluminescent region (1). Since the electroluminescent device comprises a heating element (7) for applying heat to the electroluminescent region (1) and a heating control unit (9) for controlling the heating element (7) in applying the heat, the color point can be adjusted in a simple way by using the heating control unit (9).
