摘要:
The invention relates to a lighting device for generating output illumination having at least one directional characteristic. The lighting device includes at least one light-emitting device and at least one optical element disposed in an optical path of the light-emitting device. The lighting device also includes a screen-like member for changing at least one physical property of light passing therethrough and an optical device for generating an intermediate image on the screen-like member. The screen-like member and the optical device are located in the optical path between the light-emitting device and the optical element projecting the intermediate image.
