An LED lighting assembly (1) comprising a cassette (2) having a lens (4), a printed circuit board (6) having at least one LED bulb (8) mounted thereon; an optic (22), surrounding each bulb (8) and extending between the printed circuit board (6) and the lens (4), and an electrical connector (28) and wherein the lens (4) is arranged to provide a predetermined light pattern (38) defining a personal passenger space which may comprise a non-circular shape. The lens (4) may comprise a first lenticular lens (46) having an array arranged in a first direction and a second lenticular lens (54) having an array orientated at an angle to the first array. An adjustable aperture means (1034) may be used to control a light output from the assembly (1). The assembly may comprise a number of apertures (1012, 1014) in at least an outer part of the cassette (1000) and a relative arrangement of the apertures (1012, 1014) may be such that air is drawn into the cassette (1000) and over the printed circuit board (1002). An electrical connector (1024) may be arranged to comprise a number of openings (1032) arranged such that air can flow through the connector (1024). |
