Beschreibung
Zusammenfassung:	A lighting unit comprises an optical component ( 1 ) having an interior surface ( 3 ) and an exterior surface ( 5 ), the interior surface ( 3 ) of the optical component ( 1 ) for receiving a beam ( 10 ) of collimated light incident thereon, and the exterior surface ( 5 ) forming an exterior surface of the lighting unit. The optical component ( 1 ) comprises a plurality of Fresnel or diffractive lens elements ( 9 ) arranged to focus the beam of light ( 10 ) to a corresponding plurality of points in a predefined pattern on the exterior surface ( 10 ) thereof. The exterior surface ( 5 ) of the optical component ( 1 ) is provided with a substantially opaque mask ( 7 ) which is patterned with apertures at a plurality of points corresponding to the predefined pattern so that the light may emanate therethrough.
