A lighting system for an aircraft cabin includes an electrical light source and a photoluminescent light source. The electrical light source is provided at or near a ceiling of the aircraft cabin and the photoluminescent light source is arranged at or near floor level. The photoluminescent light source defines a path along which passengers can move to an exit and is located in an area that receives a light output from the electrical light source to charge the photoluminescent light source. The electrical light source is adjustable to alter the orientation of the light source to concentrate the light output in the area of the photoluminescent light source to enhance charging of the photoluminescent light source by the electrical light source.

A carpet display system includes a plurality of carpet modules. Each of the plurality of carpet modules includes a translucent support panel, a carpet layer secured to the support panel, and a light-emitting element coupled to the support panel. The light-emitting element is configured to emit light through the support panel to provide lighting effects through the carpet layer.

A light unit executes up to three different functions (cabin area illumination, individual/dedicated/decorative illumination and emergency illumination) and an emergency illuminated sign unit, each one with an internal controller and a rechargeable capacitor. An example non-limiting embodiment also provides a cabin light system and an emergency lighting system, where each illumination unit (light source or illuminated sign) is as described above.

An escape path marking for an aircraft includes a lighting element, which luminesces in a dark environment, and which emits an emitted light which exits at an outer side of the escape path marking. A transparent protective element is arranged between the lighting element and the outer side of the escape path marking. A planar grid element, which comprises regularly alternating pure-color transparent and opaque regions, is arranged between the lighting element and the outer side of the escape path marking. A transparent pigmented element is formed and arranged between lighting element and the outer side of the escape path marking such that in an event of external illumination according to at least one predefined illumination scenario, a predefined first color tone results on the outer side of the escape path marking at the transparent regions of the grid element.

A lighting arrangement comprises a carpet structure and a control unit. The carpet structure includes a carpet back lighting system comprising a carpet back lighting unit having a lighting unit front face and a plurality of light sources. The carpet structure further includes a light transmissive carpet unit comprising a carpet unit front face and a carpet unit back side. The lighting unit front face and the carpet unit back side are adjacent. The carpet unit is arranged to transmit at least part of the light travelling in a direction from the carpet unit back side to the carpet unit front face. The control unit is configured to receive one or more input signals and is configured to generate, in response to one or more input signals, one or more output signals to control the light generated by the light sources.

An emergency lighting element includes a planar, electrically operable radiation source for planar emission of electromagnetic radiation at a front side of the radiation source; and a long-afterglow layer over a whole area on the front side of the radiation source. A penetration depth into the long-afterglow layer for radiation emitted by the radiation source corresponds at least to a thickness of the long-afterglow layer. The long-afterglow layer comprises phosphorescent material, an absorption spectrum of the long-afterglow layer at least partly overlaps an emission spectrum of the radiation source and an emission spectrum of the long-afterglow layer lies substantially in a visible range.
