INTERIOR AIRCRAFT LED LIGHT UNIT AND METHOD OF CALIBRATING AN INTERIOR AIRCRAFT LED LIGHT UNIT

An interior aircraft LED light unit (2) includes at least one LED (6) and a lens cover (12) arranged over the at least one LED (6), the lens cover (12) having a proximal side (12a) facing towards the at least one LED (6) and a distal side (12b) forming an outside portion of the interior aircraft LED light unit (2), with the lens cover (12) being made from a lens cover material exhibiting material-specific light transfer properties. The lens cover (12) comprises a pattern of dots (16) on the distal side (12b), with each of the pattern of dots (16) locally altering the material-specific light transfer properties of the lens cover (12).
