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.
摘要:
A segmented electroluminescent device (100) with resistive interconnect layers (102), each segment (104,104′, 104″) comprising an electroluminescent layer (110) arranged in between a first (106) and a second electrode (108) layer. The segments (104, 104′, 104″) are connected via resistive interconnect layers (102), the resistive interconnect layers having a larger square resistance than the second electrode layer. The resistive interconnect layers (102) add a ballast resistance to the electroluminescent device such that no additional electric ballast is needed. As the electric ballast is divided over multiple layers the problem of a heat management for the electric ballast becomes less important. By adding an isolation layer (122) the surface of the resistive interconnect layers (102) can be increased to almost the whole surface of the electroluminescent device (100). The system of the electrode layer (108), the isolating layer (122) and the resistive layer (102) functions as a capacitor.
