Interior aircraft light unit and method of producing an interior aircraft light unit

Method of producing an interior aircraft light unit, comprising the steps of:

• providing at least one light source, emitting light with a source side light intensity distribution,
• measuring the source side light intensity distribution of the at least one light source and determining regions of different light intensity in the source side light intensity distribution, the regions of different light intensity comprising at least a first intensity region and a second intensity region, with the first intensity region having a higher light intensity than the second intensity region,
• providing a semi-transparent layer having a transparency distribution with regions of different degrees of transparency, the regions of different degrees of transparency comprising at least a first shading region and a second shading region, with the second shading region having a higher degree of transparency than the second shading region, and
• assembling the semi-transparent layer between the at least one light source and an outside of the interior aircraft light unit, with the semi-transparent layer being placed in such a way with respect to the at least one light source that the first shading region corresponds to the first intensity region and that the second shading region corresponds to the second intensity region, wherein the semi-transparent layer transforms the source side light intensity distribution into an adjusted light intensity distribution that is closer to an even light intensity distribution than the source side light intensity distribution.
