Patent ID: 7316486

Claim:
A lighting arrangement ( 1 ), for the interior lighting of a vehicle or aircraft, comprising a plurality of light emitting diodes ( 2 a - 2 e , 3 a - 3 d , 4 a - 4 c ) of at least two groups ( 9 , 10 , 11 ), said light emitting diodes being arranged on a surface element ( 5 , 5 ′, 5 ″), wherein each group ( 9 , 10 , 11 ) selectively includes at least one light emitting diode or a plurality of light emitting diodes ( 2 a - 2 e ; 3 a - 3 d ; 4 a - 4 c ) of the same kind, light emitting diodes ( 2 a - 2 e , 3 a - 3 d , 4 a - 4 c ) of different groups ( 9 , 10 , 11 ) being of different kinds, and wherein the light emitting diodes ( 2 a - 2 e , 3 a - 3 d , 4 a - 4 c ) are distributed in an overall two-dimensional geometrical pattern ( 13 ) on the surface element ( 5 , 5 ′, 5 ″); and the centroid (R) of the overall pattern ( 13 ) being located on a center line ( 8 ) of the surface element ( 5 , 5 ′, 5 ″), the light emitting diodes ( 2 a - 2 e , 3 a - 3 d , 4 a - 4 c ) of at least one said group ( 9 , 10 , 11 ) with at least three light emitting diodes being arranged distributed in a two-dimensional geometrical group pattern ( 18 , 19 , 20 ) on the surface element ( 5 , 5 ′, 5 ″) such that the centroids (R 1 ; R 2 ; R 3 ) of the respective group patterns ( 18 , 19 , 20 ) are each similarly located on the center line ( 8 ) of the surface element ( 5 , 5 ′, 5 ″); at least two of said group pattern centroids (R 1 ; R 2 ; R 3 ) are located along said center line ( 8 ) at separate points so as to avoid coinciding with one another, and wherein at least two of said groups ( 9 , 10 , 11 ) differ in the respectively therewith associated number (N m ) of light emitting diodes ( 2 a - 2 e , 3 a - 3 d , 4 a - 4 c ).
