Abstract:
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.
