Abstract: A system for combining exterior light with artificial lighting, comprising a light shielding arrangement (2) for shielding exterior light from a space (5) and at least one light source (6) arranged to emit artificial light that is directed toward the exterior side of the light shielding arrangement (2), which light source (6) is controllable in response to current exterior lighting conditions. The system further comprises a controller (8) connected to said light source (6), which is arranged to control light emission of the light source (6) in response to a current position of the light shielding arrangement, so as to emulate an effect of exterior light escaping through the light shielding arrangement. The artificial light can thus be controlled (manually or automatically) to compensate for lack of sufficient exterior light, and the controller ensures that the artificial light is emitted in such a way as to be perceived as exterior light.

Notwithstanding this, the diffractive features also extract light such that the lighting device illuminates a reference surface, disposed at an intermediate distance from the light guide, with illumination light that is substantially uniform in color and substantially white. Optical films having diffractive features that can be used to construct such devices and light guides are also disclosed.
