1. A lighting unit comprising:
a light-emitting element (LEE);
a light guide extending from a first edge to a second edge and configured to propagate light entering the light guide at the first edge to the second edge of the light guide;
a coupler arranged between the LEE and the light guide and configured to couple light emitted by the LEE into the light guide at the first edge of the light guide; and
an extractor having an input aperture and an exit aperture and opposing side surfaces extending between the input aperture and the exit aperture, the exit aperture being defined by a convex surface spaced apart from the input aperture, the exit aperture being larger than the input aperture, and first and second side surfaces flaring from the input aperture of the extractor to the exit aperture of the extractor, wherein:
the input aperture of the extractor is coupled to the second edge of the light guide
the first and second side surfaces are shaped to direct light from the input aperture of the extractor directly to the exit aperture of the extractor, the first side surface being a concave surface,
the lighting unit emits light from the exit aperture of the extractor during operation, and,
the lighting unit is a vehicle light lighting unit.
