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 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. LEDS may be used as the light source, and the beam may be reflected by a parabolic mirror 12.
