Abstract
A lighting unit which comprises a lens arrangement over a LED module is provided. The lens arrangement comprises a plate having at least one lens integrally formed by the plate for positioning over a substrate of the LED module, and at least one magnifying component integrally formed by the plate. The LED module substrate has an inspection region which is inspected through the magnifying component, so as to enable determination of a spacing between the lens arrangement and the substrate by viewing an image of the marker arrangement created by the at least one magnifying component at a given viewing location. A luminaire is also provided, which luminaire comprises a housing and the lighting unit mounted within the housing, wherein the lens arrangement (10) forms the light output window of the luminaire.
